"Extreme porn" laws tested (This post will make you a criminal)

2011-01-05T10:57:00.000-08:00

WARNING!

Viewing this post may make you a criminal!

WARNING!

This will probably not pop up much but it is worth noting that a person is now on trial for possession of so called "Extreme porn". No mention of what the porn is other than that they showed "injury to a person's breast" and "an act which threatens a person's life". Given that this could cover image of a nipple piercing:

and strangulation:

both of which I'm sure appear in films, TV and now this webpage it's kind of a stupid thing to prosecute over, especially as the making of these images is not illegal: just their viewing (sorry you are now a criminal).

Anyway stupid law is stupid and hopefully this won't go through

I am spartacus

2010-11-17T04:08:00.000-08:00

Very quick post; two things of note happening online at the moment. The first thing is the ruling that the following text:

"Crap! Robin Hood airport is closed. You’ve got a week and a bit to get your shit together, otherwise I’m blowing the airport sky high!"

sent via twitter constitutes a menacing and dangerous message to send (Paul Chambers lost his appeal), here's Index on Censorship's post on it and my thoughts at the start of all this. This lead to a lot of people retweeting Paul's original message with the tag "#IamSpartacus' in a show of solidarity and to point out the stupidity of the ruling (BBC coverage here). In essence this ruling could be interpreted as the outlawing of humour in public forums, well certainly the sort of humour that some could misinterpret. In fact there was a second case of this on the same day when Councillor Gareth Compton was arrested under section 128 of the 2003 communications act (I think) for making an ill conceived attempt at humour when asking:

"Can someone please stone Yasmin Alibhai-Brown to death? I shan't tell Amnesty if you don't. It would be a blessing, really"

to put this in context Yasmin Alibhai-Brown had just just complained that politicians (other than the likes of Nelson Mandela) weren't morally allowed to comment on human rights issues. While neither of these jokes are very good it's pretty obvious that they're not serious incitements or threats so quite why they're treated (and apparently tried) as such is beyond me (and worrying me).

Second item is shorter (for my part at least) the Met Police apparently have the "authority" to take down websites, without a court order, or any judgement, if they are found in "contempt of court" (well if they Met think they're in contempt of court at least). Here's there second Spartacus moment: Fitwatch is removed at the request of the Met, so they get reposted everywhere what were they posting? how not to pulled up by the police if you've been in a demo. There's a very good analysis of why this whole story is wrong at Heresy Corner and here's the offending blog post from FitWatch (I don't condone violence etc but posting this is not illegal):

"If you fear you may be arrested as a result of identification by CCTV, FIT or press photography;

DON'T panic. Press photos are not necessarily conclusive evidence, and just because the police have a photo of you doesn't mean they know who you are.

DON'T hand yourself in. The police often use the psychological pressure of knowing they have your picture to persuade you to 'come forward'. Unless you have a very pressing reason to do otherwise, let them come and find you, if they know who you are.

DO get rid of your clothes. There is no chance of suggesting the bloke in the video is not you if the clothes he is wearing have been found in your wardrobe. Get rid of ALL clothes you were wearing at the demo, including YOUR SHOES, your bag, and any distinctive jewellery you were wearing at the time. Yes, this is difficult, especially if it is your only warm coat or decent pair of boots. But it will be harder still if finding these clothes in your flat gets you convicted of violent disorder.

DON'T assume that because you can identify yourself in a video, a judge will be able to as well. "That isn't me" has got many a person off before now.

DO keep away from other demos for a while. The police will be on the look-out at other demos, especially student ones, for people they have put on their 'wanted' list. Keep a low profile.

DO think about changing your appearance. Perhaps now is a good time for a make-over. Get a haircut and colour, grow a beard, wear glasses. It isn't a guarantee, but may help throw them off the scent.

DO keep your house clean. Get rid of spray cans, demo related stuff, and dodgy texts / photos on your phone. Don't make life easy for them by having drugs, weapons or anything illegal in the house.

DO get the name and number of a good lawyer you can call if things go badly. The support group has the names of recommended lawyers on their site. Take a bit of time to read up on your rights in custody, especially the benefits of not commenting in interview.

DO be careful who you speak about this to. Admit your involvement in criminal damage / disorder ONLY to people you really trust.

DO try and control the nerves and panic. Waiting for a knock on the door is stressful in the extreme, but you need to find a way to get on with business as normal. Otherwise you'll be serving the sentence before you are even arrested."

Creator but not a God

2010-10-18T10:05:00.000-07:00

I've been asked from time to time how I can study physics and yet not believe in god (or gods). My reason is simple: I don't see any evidence for a god so why should I believe in one? What I will allow, as a possibility, is a creator. This is where most people get confused so I'm going to attempt to explain exactly what I mean.
As it stands science (precisely cosmology and quantum physics) cannot state what happened before the big bang; it's a singularity which means that the mathematics of describing the universe stops working. The upshot is that there is nothing that we observe that can tell us what happened 'before the big bang' even such a question is meaningless as we don't even know if time existed. The obvious assumption made by my theist friends is that this is where god (the creator) sits and makes the universe; therefore there is god; therefore that god is god X (normally the Christian God but change as appropriate). It's the last two assumptions that I have a problem with; there is no reason that the creator is still here and certainly no reason to believe (s)he is god X.

So I believe a creator is possible: although I don't believe there is one, I just acknowledge that there is no way to make a definitive statement either way. If there was a creator (s)he doesn't seem interested in making her/himself known to us even if (s)he is still there.

The final point I think I've made before but I hope to put it more elegantly: in all odds any creator is a computer programmer. Our society has made virtual worlds and there is no reason to assume that you would be able to tell that you were in a simulation over the real thing (no, if you squint hard enough you don't get to see the world as green lines of text you just get a headache) so there are pretty good odds that a more advanced civilisation has just simulated our world.

In summary: there is no god, there might be a creator but if there is he's most likely using this world for porn (don't believe me? how much of the 'net is porn... there you go).

I was going to write a post about how chaotic and unstable systems work in maths and how you see this in stock markets, also commenting on why the idea of "no more boom and bust" is rubbish.

But I should instead be writing my first year report so I'll leave the link to the post that inspired this all and maybe come back to it later

So: the weird patterns left through stock markets: bots stuck in loops, random noise from algorithmic cross chatter, market sabotage or strong AI's lurking online messing with us? you decide!

Ground zero mosque

2010-08-27T06:02:00.000-07:00

This will be a short post a) because I should be doing something else and b) because it's mainly a vehicle to post this link to newsbiscuit's take on the whole incident.

That being said I will say this about the debate: "why are we having it?" it's utterly stupid. Yes it may not be the most sensitive thing to build there but it's not actually a full mosque (more a community centre with a prayer room) but that being said they still have every right to build it there and that should be it.

It seems that people seem to forget that freedoms apply to everyone: I may not like organised religion but if you really want to do it I'm not going to stop you unless you start trying to impinge upon my freedoms...

ah well, hopefully the news biscuit article will help some people perform self rescue from the predicament of having a rectal-breach-head.... we can but hope

Changing seasons: why do the radioactive isotopes slow down in summer?

2010-08-24T07:21:00.000-07:00

There is a very interesting (and possibly very significant) story [1] doing the rounds of various [2] science [3] sites [4] at the moment (New Scientist, [4], got to it last year before the paper was published). The story relates to a simple finding from Purdue University: that radioactive decay rates may not be truly constant; they seem to vary (almost imperceptibly) according to the season, solar flare activity and with the rotation of the Sun's core (apparently one rotation every 33 days). The article can be found on arXiv[5] (or in your trusty copy of the proceedings of "the Fifth Meeting on CPT and Lorentz Symmetry") but I will try to analyse it myself, here.

The basic premise is this: radioactive atoms decay randomly, a single atom of Uranium could decay the second you look at it or in 5,000 years time and there is no way of knowing which it will be. Given a large enough group of Uranium atoms and they will undergo a predictable average number of decays within a given amount of time (for example 500±5 decays every second) so while you can't say that there will be 50 decays you know that there will almost certainly be between 45 and 55. To predict the expected number of decays per second (as well as the range into which it falls) a constant called the 'decay rate' [6] is used. Previously it was thought that is was a pretty solid constant (a fact that atomic clocks are built around) and that while the exact number may change it did so according to some well understood statistics.

It was research into the randomness of radioactive decays (for random number generators or dice as they are known) that brought the anomaly to light: when measuring the decay rate of Manganese-54 [7] dips in the count rate (actual number of decays) were noticed that strongly correlated with peaks of solar flare activity seen in December 2006 (Fig 1 [8]). According to the statistical analysis [8] the probability of such a coincidence between decay rates and a solar flare of that strength (S2 which occur ~25 times in each 11 year solar cycle) seen on 12th Dec is roughly ~$10^{-13}$ so the probability of two such events seems very small indeed.

Fig 1. "Normalized December 2006 54Mn decay data along with GOES-11 x- ray data on a logarithmic scale. For 54Mn, each point represents the number of counts in the subsequent four hour period normalized to the average decay rate
(see text), and has a fractional $\sqrt{N}$ statistical uncertainty of ~2x10$^4$. For the GOES-11 x-ray data, each point is the solar flux in W/m2 summed over the same real-time intervals. The 12 December peak in the x-ray flux occurred at ~21:37 EST." [8]

As well as manganese similar evidence has been seen over month long periods as the sun's core rotates. The analysis [5] shows uses a Joint Power Statistic [9] (JPS) to measure the correlation between the decay rate and the inner core activity of the Sun. Again this analysis claims a remarkable accuracy (the likelihood of such a result is claimed to be 1 in $10^{12}$) but the technique used (JPS) is not one I am familiar with so I can't (yet) comment on it; once I have read the article [9] I will try to.

The final piece of evidence[10] for solar effects on decay rates comes annually: by looking at the count rates of various other radioactive isotopes (Silicon-32 [11] and Radium-226 [12]) over the course of a year these show strong but small affect (1 part in 500).

One hypothesis is that this is caused by changes in the neutrino flux. This seems strange as none of the isotopes undergo neutrino induced decay (as far as I can tell). It may be that the Weak nuclear force field that the neutrinos interact via is needed to trigger decay (although as I have not seen the relevant data on whether there is an excess or dearth of neutrinos it's hard to guess). Either way it will be giving a lot of theorists something to puzzle over and may give us a useful way of inspecting the internal working of the Sun, if it is correct it suggests that the core of the sun rotates more slowwly than the rest of it and may offer other methods of probing regions that are not easily inspected.

Assuming that there is a real effect on display here there are two things that we can do: firstly study in depth any data that emerges from the recent[13] solar activity which may show some disturbances depending on the make-up of the flare, the 4th August was a Coronal Mass Ejection (CME) rather than a radiation storm. Secondly see what emerges from other solar radiation storms which will, no doubt, be well documented.

Quick note

2010-07-18T06:11:00.000-07:00

Hey guys,

Just a quick note: some of you may have noticed a huge increase in the number of posts here, that's because I've imported all my old posts from 'folklore of pitong' because I realised that this blog was pretty much the same as the old one so there was no point in trying to keep them separate.

So if you never looked at the old blog (shame on you!) you can skim back through all my previous writing which I suspect is even worse than the drivel that I've already posted here.

In other news I've been working late a lot this week so hopefully work will be done soon as I have a couple of blog posts that I want to put up here, until then enjoy!

Links for those of an enquiring mind (or with 30 minutes at work)

2010-07-14T04:54:00.000-07:00

I admit this isn't a proper post but my excuse is that in the past 36 hours I've worked for 23 and only slept for 7.

Anyway here are few interesting links that I've found today:

First up with 'the wire' being my primary source of entertainment for the last few weeks this piece from the BMJ on "An alternative to the war on drugs" rings very true and seems to talk a lot of sense: in essence no matter what a government does people will still take illegal drugs, in turn this will stress the system as a) there is no tax on drugs money and b) police investigations in to drug dealing cost a lot more than treating the drug users. No matter whether you agree with the piece or not it's well worth a read as a very pragmatic view on the continuing "war on drugs".

Second up is a wonderful list of science policy blogs in the UK. If you're not a scientist this will probably be of limited interest but as I'm fairly sure this is mainly read by my friends and you're all of a sciencey-bent I figure that you'll find something of interest in there.

Finally is my latest favourite comic: scenes from a multiverse a series of daily 4 panel comics from various facets of our multiverse.

Anyway I'm off to finish watching 'the wire' which is my penultimate recommendation (yes a piece of old media) if you haven't watched it get a copy and watch it: it is one of the most thought provoking bits of TV I've seen in a while. Excellent depth and "ohhh that's what that was about" moments. Maybe not the happiest series in the world and certainly doesn't pull any punches on the realism but well worth a watch.

Before I scoot this is my final recommendation: "Accelerando" by Charles Stross (another bit of old media I know but available as an e-book) if any of my mentions of 'transhumanism' or 'the singularity' confuse you: read this it will at least help explain what they mean. An excellent book about the near future and the possible affect of AI.

DOOR OPENS

MUM:
just what are you doing young man?

SON
Nothing, mum, just a bit of writing.

MUM
writing eh? what's this, a sampler? what do you need one of these for?

S
It's for a project at school, mum, honest: we're writing our own morphers

M
I don't care what you're doing you know what I think about these ... things... it's un-natural, look what happened to your father

S
I know mum but I need to know this to..

M
To what? to get a good programming job? like your father! I forbid it. You've seen him, kept in that quarantine; everything they try gets chewed up and spat back out. You are not following him down that path.

S
But mum it's much safer, those genomes are restricted. Hell, most samplers/writers can barely write a virus that has an effect longer than 3 hours, they're struggling: the body is smart. It's difficult to write something that works anywhere near as well as dad's...

M
Don't lie to me I know the truth it's difficult to write it well and make it safe.

M snatches a device from the table.

M
no more, if I catch you with one of these again you'll be grounded, I'll just go and explain to your teacher what the situation is.

S
Mum... I need it, how else will I be able....

M [interupts]
Not another word from you - finish your maths and then go to bed, I'm sorry I ever let you even look at that subject....

M leaves

S loitering looks up as a person, A, approaches then relaxes as he's recognised

S
how'd it go?

A
perfect, they're all tripping balls and none the wiser....

S
excellent, keep it that way or otherwise we're both dead: you when they find out and me if my mum finds out.

A
I still don't know how you did it, especially after your mum nabbed your sampler..

S
Well by that point it was pretty stable and the models are good now... that and my dad's notes are awesome

A [worried now]
They're not going to end up like him are they?

S
As if you care

A
I do if it means the cops or bios are brought in

S
it's fine Dad left some detailed notes and I spotted the error he made.. just wish I knew how to fix it

[pause]

A
Just to check I can't pick up that virus can I, I mean I was careful but I'd rather not spend the next day seeing pixies all over the place if it's the same to you..

S
Don't worry I made sure that both your's and mine genomes were well exempt and if you're truly worried use this

S hands A a vial

S
it's an antidote will clean you nice and clear, that being said you might enjoy the expierence: either way enjoy and don't get dyed blue again!

B
I don't know, they make my job easier. I have two goos to monitoring the inbounds and sorting them and a symb that deals with trouble makers.

B: hell no, I hate that stuff at the best of times, even just letting the machine do the scan makes my skin crawl
A: so you've tried it?
B: only a few times, and never with something as shady as this set up.

C convulses letting out a louder moan, as he does he rolls over revealing goo covering part of his face

A: What do you think he was doing then?
B: well it looks like a cheap narco-unit, read in the 'NA [SAID 'neigh'] spit out the perfect meal
A: sounds fun.. what do you think went wrong
B: Well looks like he was using illegal codes for it

C groans again, a stronger convulsion

A: Anything we can do for him or should we just let it run it's course
B: It looks like it's getting worse lets do a quick clean up run

B pulls out a device similar to the one beside C but better looking, detaches a pipe that runs to a large store of goo and plugs in his own device. he then runs the device over C letting some of the goo touch C's hand [device could be phone or something similar in largish box or possibly out of shot only the pipe showing - vacuum cleaner?]

B: there that should stabilise him until the ambo gets here.
A: think he'll make it?
B: of course, the guy was only making dinner, looks like some git pranked him more than anything.
A: so you never use those?
B: I do but only the one at home, it already has my genome so it doesn't need to scan me, why don't you?
A: I don't see the point, I tend to eat out anyway so I just grab something from a corner stop

Unraveling the Bayesian knot: the magic of probability

2010-06-30T19:19:00.000-07:00

There is a wonderful maths problem called "the two children problem" invented by Martin Gardner and it runs like this:

you meet a friend in the street, you know he has two children but not their sexes. As you are talking a boy runs up who is introduced as your friend's son: what is the probability that the other child is also boy?

Intuition would say 50%, in this case intuition is wrong; I will now try to explain why before giving the answer.

First I want to explain some fundamentals of statistics. First and foremost is the concept of probability, this is intuitively easy to describe: "the likelihood of an event occurring" the actual calculation is also deceptively simple:
\[ \frac{\text{desired outcome}}{\text{all outcomes}} \]
where desired outcome is all the ways of achieving the outcome you're interested in (for example a boy in the above problem) and all outcomes are all the possible outcomes (eg boy or girl) so for the sex of a child the result, as you would expect, is:
\[\frac{\text{boy}}{\text{boy}+\text{girl}} = \frac{1}{2} = 50\%\]

The above of calculation is very simple but problems arise when you start looking at adding probabilities. For example the probability of having 2 sons is $\frac{1}{4}$ there are 4 possible combinations of 2 children (2 sons, 2 girls, 1 (eldest) son 1 daughter, 1 (eldest) daughter 1 son) while the probability of having a son or a daughter remains $\frac{1}{2}$ the probability of a particular number of sons or daughters changes. While this may not make immediate sense it is easier to understand by going to an extreme: instead of 2 sons what are the odds of 200 sons? (answer below, it's very unlikely; even without considering the physical problems). A series of trials like this is where the 'Gambler's fallacy' comes from, each trial is independent, it has no effect on the outcome of any of the other trials, but any particular combination has a different chance: having 199 sons then a daughter is as likely as 199 sons then another son. The chance of having just 199 sons and daughter is more likely as the order of birth doesn't matter. There is only one way to have 199 sons then a daughter but there are 200 ways to have 199 sons and a daughter.

This is the one of the big pit-falls of probability (hence the fallacy) at each trial (in this case birth) the probability is the same, any one of those 200 children has a 50-50 chance of being a son or a daughter but any particular combination of children will have its own probability. At this point the essence of the 2 children problem should start to become apparent.

So what the answer to the 'two children problem'? It's not actually $\frac{1}{2}$ or $\frac{1}{4}$ , it's $\frac{1}{3}$. To understand this think back to the definition of probability, we know that for 2 trials with each trial having one of two outcomes we have 4 possible outcomes:

2 sons, 2 daughters, 1 son 1 daughter and 1 daughter 1 son

Now we know that one of those options, 2 daughters, is impossible because we already have already met one son so that leaves us 3 options: 2 sons, a daughter or a different daughter (say, an older or younger daughter). The two options for a daughter may seem needless but it is vital: we know that there were 4 states and only one of those states is removed (2 daughters). We know at least one child is a boy but nothing more, if we knew the eldest child was a son the probability of the other child being a son would be $\frac{1}{2}$ but unless we know that this is a similar case to having 199 sons and a daughter: more likely because there are more possible 'desired' outcomes.

This sort of calculations relies on a branch of probability known as Bayesian statistics which concerns itself with the combination of different probabilities. This example is among the simplest and already it clashes against classical intuition, the most impressive part is that the probabilities are exactly what we see when we go and test these systems (you can do it yourself with two coins instead of children).

Of course one other reason the two children problem causes such confusion is the utterly artificial way in which it is presented but real world examples do exist, for example: given the probability of a disease test giving the correct result and the probability of having that disease how likely are you to have the disease if you test positive? Just so you know the answer is not $\frac{1}{4}, it is different as each outcome is not equally likely (for example you might have a 0.2% chance of having the disease and a 1% chance of a the wrong result from the test). For those that want an even more mind-bending problem I direct you to the Monte-hall problem, or the inspiration for this post: the Tuesday two children problem (if you know the son you meet was born on a Tuesday how likely is it your friend has another son).

200 heads from 200 flips? its:
\[ \left( \frac{1}{2}\right)^{200} = \frac{1}{1606938044258990275541962092341162602522202993782792835301376}\]

Science: the other bit

2010-06-28T21:54:00.000-07:00

I've been working in Japan for 2 weeks now and I've spent most of that time working on an experiment. Of that time about 1 day was spent taking data, the rest was spent working on analysis. Analysis is the bit of science that most people forget. People look at the LHC and expect it to run for a while and then spit out an answer. Does the Higgs exist? yes or no. Are there extra-spatial dimensions, how many? Can lepton flavour be violated? maximally or only in rare cases?

These are all questions that the LHC may answer, but not immediately, not even quickly in anything other than a scientific time frame and the reason for this is analysis. Analysis probably accounts for most of the time spent on an experiment. Before the LHC was even finished being built people had been running analysis for years and will run it for many more years once it shuts down. The reason for this is that every last bit of data has to be accounted for.

The experiment I have been working on for the last 2 weeks has been the calibration of a scintillation detector, to do this a radioactive source is placed near the detector and the detectors response is measured. This measurement then produces a plot that looks a little like this:

The big peak on the right is caused by Cesium 137. This peak lies at 662keV, and is used to calibrate devices because the position of this spectral line can be calculated from what we know about the nuclear make up of cesium.

In this case it would seem to be a fairly simple analysis but it isn't a complete analysis, what about the two smaller peaks to the left of the big 662KeV peak, what is the huge peak near zero? The smaller two are called the backscatter peak and the Compton edge respectively, both are caused by scattering processes that the gamma ray (the source of the big peak) can undergo and ultimately mean not all the energy is accounted for hence the lower energy peaks. This leaves only the big left hand peak, caused by hard x-rays emitted when electrons move in their orbits (de-excite), gamma rays are caused by entire nuclei de-exciting hence their higher energy.

The above paragraph is a reasonable, qualitative analysis of the above graph but by no means is a full, rigorous analysis. For that the position of each peak would have to be calculated (for several other sources as well as cesium), carefully modelled using the expected curve which is then fitted to the data, the parameters produced can then be inspected and checked against the initial assumptions to see that there were no obvious differences from the expected.

The process above is what I did over the last two weeks. Two weeks of analysis for less than 2 days of data taking.

The LHC has orders of magnitude more complexity and a nearly unimaginably large amount of data taken every second (at the raw data rate it produces several thousand times more data than can be written to hard drive using current technology). The analysis of its data has been planned meticulously for the last decade, in fact the entire LHC has been modelled and simulated many times for various different possible physics scenarios (even black holes) over the last decade just so we'll have an idea of how it would look. These simulations have produced analysis procedures that can be applied to the data as soon as it exists.

Once the initial data analysis is done it may be revisited several times: there are people in my lab working on data taken at the Zeus experiment (an smaller version of the LHC based in Hamburg, Germany). Zeus stopped taking data in 2007, 3 years later it is still being looked at and depending on what gets discovered at the LHC another round of analysis may begin: signals that were too weak to be noticed may be looked for with different techniques or better initial parameters.

Analysis is where the real science happens: experiments just make something to analyse. Already people are analysing the LHC: checking its calibration, looking for early signs of the Higgs. But the data taken now may be revisited a hundred times before it's fully understood, the meaning of ever last wrinkle, dimple and bump fully understood by which time the next set of experiments will be firing, fusing and flickering towards the next data set.

The weekend that was (very wet and misty)

2010-06-28T07:48:00.000-07:00

As the title says: the weekend was ~~blurry~~ misty. Saturday it rained, a lot, Sunday was sunny, a lot. That's my obligation as British national disposed of I can now actually talk about what I did. Which to be fair wasn't much either.

Friday night I managed to sort myself out so that I could go out with some of the guys from the lab. Unlike typical trip to the local pub (certainly for my department anyway) here it meant we went to a bar which served good food as well, frankly this was a double wammy of win that was improved by the fact it was pretty cheap. About 5 rounds of drinks as well as about 15 different dishes worked out as about ¥3,000 each (about £25) given that in London 5 drinks alone will set you back most of that I consider it a good evening.

The food was really good, mainly small bits but it mounted up and by the end I was full(ish). Some interesting things I tried included: chicken cartilage (chewy but nice when deep fried in batter) octopus and squid in various forms (all of them dead) as well as something that was a called 'mountain potatoe' and when cooked had something close to the consistency of mucus, that being said it still tasted awesome as it absorbed pretty much any flavour put in it.

Saturday was a lot wetter than I was hoping for but I'd planned to be inside so no real loss: I went to the Osaka Aquarium (Kaiyuken) which like the biggest aquarium in any country instantly makes it something not to miss (according to the guidebooks and most likely the money given to the guidebook's authors). In this case it was reasonably justified as I doubt it'll be many years before I see sunfish, finless porpose or whalesharks in the same place (or at all given their survival chances).

From Osaka Aquarium

I felt a little bad as a lot of the tanks there seemed small (especially for things like dolphins, sea lions and the whale sharks) but nothing seemed actively insane so hopefully they're ok. Obviously I saw more than those listed but a lot of what I saw were fishes: interesting to me but I'm not going to list them here (although I have to say the Jellyfish were awesome... but maybe that's just me).

After my pseudo-aquatic adventure (and negotiating all those children and people without GBH was something of a trial) I tried to take in the sights of Osaka through the medium of Ferris wheel (apparently the Tempozan was the largest wheel until 1997 when it lost to a rival within Japan, which lost to the London eye before several others successively claimed the title). Unsurprisingly this ended as mainly an exercise in watching the mist, and the clouds, and the rain but was nice and on a good day must be stunning (or terrifying depending on your love for heights).

After my trip I returned to the bar I'd eaten at the week before in Shinsaibashi and had more octopus (I really like it, ok?) and it's at this point the mist really rolls in. Japan is pretty easy to drink in for less than I'm used to in London and the people are very friendly: I made an friend at the bar and several hours were spent trying to understand each-other (phrase book = most useful thing ever). The excitement left me a little stranded at the end of the night when I managed to get the last subway home but missed the connection to the last monorail (pretty much all public transport bar taxis shut down at about 12:30, which is when I arrived in Senri-chou for the connection).

According to some of the people in the hostel it's traditional, upon getting stranded, to find an internet café where you can get all you can drink drinks and 'net time for a fixed fee that will cover several hours kip, unfortunately I was stranded away from a café so had the pleasure of walking home in the rain. It was actually quiet nice: my umbrella kept me dry enough (lesson the second as well as a phrase book carry an umbrella) and it was interesting (in a torrential kind of way) although any longer and I may have enjoyed it less (2 hours was more than enough time to sober up).

Home safe I slept it off on Sunday and have a coffee and reading day back in Senri-chou in the sun shine.

and now it's back to another week of poking circuits and science!

I think the heat has gotten to me .... this is a disturbingly ~~chipper~~ upbeat post... ah well maybe its tiredness.

Stuff wot I found....

2010-06-25T18:26:00.000-07:00

It's raining and I've not got up properly so before I go and enjoy the aquarium I thought I'd leave some links to some of the odder things I've found online in the last while:

Country hip-hop dancing (stampa med leyroy has competition)

And zombie pirates in love

Enjoy!

first visit to MUSIC

2010-06-18T06:06:00.000-07:00

Well I finally got to see what I'm working on today: MUSIC. Housed in the RCNP (Research Centre for Nuclear Physics) at Osaka University it is a FFAG (Fixed Field Alternating Gradient) that will be used to accelerate muons (a heavier version of the electron) these will then be studied and used to probe matter as well as generally make people go 'oooooh' (and then hopefully give us money to make us go away).

Like any good student while I was there I maintained complete decorum, for about 2 minutes. The whole facility was intensely cool, very much like something out of Half-life. As a building it is not made for humans, it's made for machines, humans just occasionally have to move around it: you're constantly ducking under piping stepping over cables, there are rooms full of boxes each controlling enough power to keep the average home going for month, the corridors are half shared with massive (utterly massive) bundles of high voltage cabling and most of the doors have fail safes on (and are generally about 50cm thick iron).

One of the strangest things about the whole site is that it's old, the first cyclotron was finished in 1973, so the whole place is well established and worryingly organic in feel at times this feeling strongest when comparing the equipment: on one hand is MUSIC, built less than a year ago consisting of finely polished metal shaped to incredible precision; on the other hand are the sections of proton beam pipe, lengths of well used metal held aloft by metal segments, controlled with magnets that are chipped and bruised.

Anyway, rather than ramble further I will leave you this link to my picasa album, it has several pictures of the experiment hall and control room - hopefully the captions will give some idea of what's going on feel free to leave questions in the comments though.

PS feel free to look at the other albums with photos from my trip so far

Email death?

2010-06-17T02:49:00.000-07:00

This is an interesting blog post on the BBC's dot.maggie discussing the recent proclamation from Chief Operating Officer at Facebook, Sheryl Sandberg, that the humble '@' is doomed. Her logic seems reasonable: that if you look at teenagers few of them use email compared to facebook and similar.

She may be right on that count but I think she's over looked one fatal flaw. Ubiquity, everyone has email (well everyone online) fewer have facebook, you need an email account to set up facebook, and buy things, and sign on to many websites. While the good 'ole boys at facebook would love to replace email it's not imminent and frankly I think their track record isn't good enough to convince enough people to use them such that they become all encompassing enough to remove email, I certainly hope they don't.

I think we'll have email for a while yet if for no other reason than it's a standard not controlled by any one group, it's by no means perfect but equally if you dislike your provider you can switch and lose very little, you don't need to convince all your friends to jump ship with you, or set up ghost accounts (like I'm thinking of doing with FB), or fake things you can simply change you email: gmail boring you? try hotmail, or yahoo, or just use a gorilla mail account that goes after 1 hour.

I think there is a secondary element she has forgetten as well which is that the Internet is no longer just about the up-and-coming teens its about everyone; email may be old but it's known, it's used a by professionals, O.A.Ps, primary school kids and teenagers. Yes, lots of people chat on facebook but I doubt many people use it or twitter to distribute minutes for a meeting or arrange how a problem is going to be tackled, and even if they did what happens if they need to leaise with someone on bebo?

I'm sure she's right, that in the long run email will die, but I expect that will only happen when something completely replaces it. Google tried with wave but failed at the same fatal flaw she missed - everyone has to use it and not realise they are using it, it has to be ubiquitous. What ever replaces email needs to be the next phone number, the next email - most likely a universal id you can pick up and put down but will always find you be it email, phone call, video call or what ever; this is not an advocacy for ID card style thing, I'm talking of a phone number (or email address or what ever) that everything is routed through. We're nearly there as this already happens on most smart phones but using a variety of different addresses (your email, your twitter, your facebook your phone all have separate accounts) the next big thing will be a combination account for at least phone, email, and probably video calls. The problem with this is that it will probably require a big chance: tele companies giving up and becoming purely supply of data while people move themselves around separately to their distributor within the Internet (I won't call it the cloud because I don't think that's what it'll be, maybe cloud 2).

The day the work began

2010-06-14T04:22:00.000-07:00

Today was my first day working in at the Osaka University physics dept. it was a bit messy. After running late (combination of late start and missing the bus) we managed to meet our supervisor out here at about 10, we then got a tour and proceeded to wow him with our lack of knowledge (seriously he looked shocked). The up shot is that I now have about 100 pages of a book to read and a 2nd year undergrad experiment, calibrate a scintillator, to do by tomorrow afternoon (can't use the lab tomorrow afternoon so some analysis can be done but we also have to give a presentation at the weekly group meeting at 6). In short it's a bit stressful, especially as the experiment doesn't seem to be working as expected.

That was pretty much my day, the weather has been clearer today (at least no rain) and hot again.

Hopefully tomorrow will be better and I can get on with some proper work, until then I leave you with an explanation for the platypus...

UPDATE: In addition to platypus I think people should read this essay on the Burqa. It explains concisely and clearly why banning the burqa is pants-on-head stupid.

Travelling in Japan (or why staying up till 6 isn't clever)

2010-06-13T05:57:00.000-07:00

Well I'm now in my base of operations for the next two months: Osaka. I started off in Tsukuba where the KEK centre in and travelled down this afternoon, and what have I learnt? That despite the assurances of my Australian flat mate travelling hungover is not a good thing.

Last night was our collaboration dinner in which our hosts took us all out for a traditional Japanese meal. It was excellent, we had our own small room and as much beer and food as we could eat in 2 hours for ¥5,000 (about £35). The food was delicious and much more than sushi: there was lots of tempura, meat and veg cooked on table top hot plates (each person had their own little burner upon which they could cook their food) lots of sashimi and all sorts of other odds and ends (giant Japanese radish for example). After this we had 3 hours of Kareoke which once you're drunk enough is a lot of fun (and after all that free beer we certainly were), a very sore throat and several bleeding ears (I can't sing) we moved to the other end of town to watch the England - USA game. By the time we finished it was 6am and the sun was up.

Four hours of 'sleep' later is was time to get up again to get down here. I have no idea how I managed this. I was supposed to be travelling with a fellow PhD student but he'd got up, checked out and then gone to sleep in his supervisor's room for the afternoon as of writing he's still not here and in an hour and a half they close reception so he's cutting it fine (I've heard he left at 6 - its a 5 hour journey). The journey itself was several parts: first a train from Tsukuba to Ahkibara (I nearly forgot my rucksack with my laptop in it luckily someone got it to me this was the same person who woke me up at the station as well people are lovely!) After this first train was a second to get me to the main Tokyo station (Akhibara is a suburb) then 2 hours on the bullet train to Osaka then another train and a monorail to where I'm staying (which is right on the outskirts).

I passed some amazing scenery on the journey and I have one photo to prove it, unfortunately for most of the time I was passed out with only intermittent bouts of paranoia induced wakefulness when my brain remembered that I may actually need to get off the train at some point.

One thing this journey taught me is how amazingly useful it is that most people know at least a little English without it I would have been stuffed, the second super useful thing is that most signs here have an English translation, that being said I'm certainly going to have to try and learn Japanese.

Anyway this will probably be revised soon once I'm actually feeling better (still a little hungover and very tired) also I'm getting kicked off the public PC I'm using (the wifi here is bricked).

First Missive from Japan

2010-06-10T14:22:00.000-07:00

Right this is an attempt at a travel log.

I've now been in Japan a day and a half having arrived late afternoon on Wednesday and it is now early morning (ie 6am) Friday.

I've not done too much so far: after arriving the four of us travelling (all of us from my group @ uni) had the joy of a further 1.75 hour bus ride to top off our 10 hour flight before we arrived at Tsukuba. A huge meal and a lot of beer later I think (I think we ordered pretty much everything off the menu) it was time for a restless night. Thursday (the first full day here) consisted of the workshop I'm attending so another bus ride followed by 10 hours of conference in a sweltering lecture theatre. We finished the day with a traditional (or so I'm told) Japanese meal which had a minimal amount of sushi but was lovely none-the-less: several small courses and a bowl of fish and vegetables on a burner.

Anyway I'm now running late if I want to get some photos taken before breakfast and another 10 hours of conference so I'm off

Travels

2010-05-26T04:21:00.000-07:00

Well once more it has been a while since I posted and as usual there were lots of things around the net that that I could have commented on but didn't (mainly due to laziness). There are a few things of interest about at the moment but I'm not going to talk about them as this has to be a quick post and you can find them for yourselves.

The main thing I'm going to talk about today is the fact that I'm off to Japan in a little over a weeks time and I'll be there for 2 months. All being well I will use this time well and hopefully keep this blog up to date with interesting ramblings (or at least ramblings) and maybe some photos.

Either way if I'm more silent than usual that's the most probable reason

Twitter bomb hoax

2010-05-10T08:42:00.000-07:00

You may have noticed I use twitter. Here is something interesting about twitter: posting something to it that could be considered menacing (say a poor joke about blowing up an airport) can now get you a £1,000 fine and a criminal conviction.

While this may seem reasonable in some light think about it for a second, a private post to a website jokingly wanting to blow up a building because of frustration has just cost a man his career. Paul Chambers tweeted:

"Crap! Robin Hood Airport is closed. You’ve got a week… otherwise I’m blowing the airport sky high!"

and (because he wanted to be an accountant for which you require a clean slate) has lost his job, £1,000 and a lot of time. All because of one stupid message. Now if he'd said:

"I'm going to blow up Robin Hood airport"

and then phoned the police with this message he would have made a hoax bomb threat and be liable for conviction because shutting down an airport for a bomb threat is no laughing matter. Whining about being stuck in the UK for a little longer and wanting to take out your frustration is another, especially when the airport clearly could see that it was a joke, in fact so could the police and the CPS. Which is why he wasn't convicted for making a bomb threat, but for mis-use of telephonic communication which is based upon a law designed to stop cold callers and stalkers.

Anyway Jack of kent has a much better summary and more detailed (and correct) legal information, I highly recommend you read what he has to say because you never know when an innocent message like:

"I want to put thermite (rust, aluminium ground and mixed then set alight with magnesium) through the engine block of the car parked near where I live who's alarm goes off every 2 hours"

spoken in frustration and anger before being sent out into the world may get you convicted for making menacing noises.

Who seizes what?

2010-05-06T05:38:00.000-07:00

There have been a couple of interesting internet developments recently: firstly facebook has continued it's slide from useful social website to yourDetailsForSale.com (which is why I have deleted my account on it) and secondly there is a further excitement about cloud computing (new about 5 years ago so new for business today). Google Enterprise is getting ever bigger; next week Microsoft launch their latest iteration of Office (with shiny online connectivity) and Ubuntu have released their latest offering complete with Ubuntu one: a 2Gb online file server (basically Dropbox).

This made me realise something: what happens when the police want to seize your computer to check it for evidence and you don't have a hard drive? I've been using Dropbox and Google Docs for about the last 2~3 years to keep a lot of my most important work backed up, but what if I was using them to keep less savoury things stored outside of my home? While at some point obviously these files would be present on my local system there are ways of making sure they never really leave any trace and so the police storming my house at 3am in the morning to take away my hard drive and decrypt it won't really do anything: the data just isn't there any more, they have to chase it to some far flung server farm.

Now while the obvious case in an individuals situation would be that the police would write to the server company and ask them to release the data and no doubt they would get emailed a nice data stream of the contents of that area. What happens, though, when it's a company they're investigating? If an entire company's data was hosted on the cloud then that's a lot of information to work through. You may only want one persons but it's no longer a case of separating out a few physical hard drives: you will have to stream however many hundreds of Gbytes of data that they could have accessed. This, of course, all assumes that you can trust the hosts and the other people in the company: if you need to get the info before anything can happen to it you may need to be a bit faster. Otherwise the hard drives you want will might not exist. The information won't be on one or two single drives either, it is likely part of a huge array somewhere in a warehouse that may not even be in the same country as the company, you or anyone else who may help. That data may also mixed in with all sorts of other information from companies you're not interested in.

My point is that if the government thought it had problems with the music industry and copyright fighting technology it hasn't seen anything. When people start leaving their important incriminating files on computers that don't even exist in any physical way run on servers in other countries that may be closely guarded by people not friendly to your cause.

Anyway as I hope I have demonstrated there should be lots of fun technology debates coming soon to a governing body near you!

Homeopathic poisoning and other rubbish

2010-04-27T04:33:00.000-07:00

This (should) be a short blog about a few things that have amused me today: firstly there is a wonderful story online at the moment about a homeopathic bomb. Although I think they missed a trick: surely making a homeopathic bomb is as easy as holding a few drops of what ever it is you want to explode above the sea and threatening to drop it (near instant dilution to an insane quantity plus sufficient shaking from waves should work wonders).

The other wonderful homeopathic rubbish I came up with is DIY homeopathic treatments: why bother spending money on diluted belladonna? By swallowing a smallish doss yourself you can let it dilute in your stomach: all you have to do is jump up and down a bit then fall over as you die and the world will be a smarter place. It's all a conspiracy by big Homie to stop people realising they can make their own placebos at home.

In other 'news' if you haven't I suggest you go and check out blag hag where as a wonderfully skeptical responce to certain stupid Iranians Jen has instigated (and analysed) boobquake. Go read it. Now.

Anyway as I said this would be a short post so it shall be. There may be something longer cropping up soon as I try my hand at some fiction - you have been warned.

In the interim I must return to poking a Clock and Control board with a probe and code. I may write about it later (you lucky devils) until then: adios!

You may not be able to fly but at least it's for a pretty reason

2010-04-19T04:00:00.000-07:00

This is an amazing picture of the Eyjafjallajökull volcano in Iceland, with its ash plume lit by lightening

It's just damn cool so I thought I would share.

Does the end justify the means: are 'Libel Tourists' a real problem?

2010-04-15T09:25:00.000-07:00

This post was prompted by something that has been annoying me for a while (since I read this excellent blog it goes into a lot of detail but is well worth the time) and in light of Simon Singh driving off the BCA (see my update earlier today) it seemed a good time to raise it. I fully support the libel reform campaign but I object to their 4th argument:

"4. London has become an international libel tribunal
We recommend: No case should be heard in this jurisdiction unless at least 10 per cent of copies of the relevant publication have been circulated here"

There is nothing inherently wrong with people coming here to settle libel cases; it is a sympton that are libel laws are in someway very attractive to other people but per say there is nothing wrong with them coming here to use them. It is the attractiveness of our libel laws that encourage people to come here to sue others nothing more. As campaign we do ourselves a disservice by falling into the trap of using people's inate xenophobia to promote our cause.

I doubt this is intentional on the part of those who lead the campaign but it does worry me the number of people who will happily repeat it without thinking about how it looks or even if its actually the problem they say it is. Who cares if people want to come here to sue each other

The only logical argument that I can see to reduce the number of people who come from overseas to sue here is if they were preventing residents from having access to the courts by clogging them up but as the number of libel cases in 2008 was 8 the made it to court from 259 that were brought this is obviously not the problem (although the apparent chilling is, even if some of these cases the defendant was obviously wrong I doubt they all were).

If anything all these people coming here with money can only be a good thing, so can we please drop the "libel tourism" and focus on what's important: that our libel laws cost 140 times that of equivalent cases in Europe, that even a successful libel defence will cost you money (to the tune of several thousand) and that more and more publishers are scared to publish here for fear of being sued or just don't publish at all.

Our libel laws are stiffling good journalism, stopping vital scientific debate and ultimately stopping the UK progressing as an educated nation; libel tourism is only a symptom of this and like homeopathy only treating the symptom does stop the problem.

Singh update

2010-04-15T04:02:00.000-07:00

It's been a while and this will only be a short post until I figure out what else I want to write about but today the BCA (British Chiropractic Association) withdrew their libel case against Simon Singh, after 2 years of hard work and the fairly heavy duty thrashing of their reputation they have realised that they were onto a non-starter.

Anyway the BBC have a piece about it here and I highly recommend you read it.

Westminster Skeptics

2010-03-16T04:41:00.000-07:00

Went along to my second Westminster Skeptics meeting last night to listen to Prof. Brian Cox, Evan Harris (MP and Lib-Dem science minister) and Nick Dusic (CaSE - Campaign for Science and Engineering) all talk about science policy as an election issues (Lord Drayson and Adam Afriyie, the Labour and Conservative science minsters respectivly were invited but didn't come).

Most of the evenings talk was preaching to the choir: it seemed to be pretty well aknowledged that science produces a overall rise in GDP (ie it you get a positive return on investment); that our economy is heavily supported by "knowledge intensive services and hight-tech manufacturing" (40% gross value added,GVA, according to the Royal Society publication on the issue that was the main basis for most of what was said - found here); that science should be publicly funded and allowed to pursue 'blue sky' as well as applied research.

There was a lot of discussion as to how difficult it is to fund science with the aim of making direct profit (ie no one in the 1980's would argue to fund CERN and expect it to produce the web) and on strategies to increase or maximise enteurpenurship within science. This centered mainly around whether the maxim that the UK "is good on science but bad on moneterisation" is true. My main thoughts are that in all areas this is tricky: firstly where obvious advancements can be made there is a lot of tough competition (for example medicine, how many people are looking to cure cancer) making it entirely possible (if not likely) that your prize research will be scooped by someone else while the bigger 'jackpots' (eg CERN and the net) are nearly impossible to predict so making investing directly for them infeasible. This means that the whole system relies on scientists spotting the implications for moneterisation themselves then being interested enough, able enough and lucky enough to get funding and support for it. I have no solutions other than better support and as much dialogue and funding as possible (and yes it's always more funding).

There was also an interesting (to me at least as they fund me) discussion on the future of the STFC.

I'm not going to weigh in on the politics of the STFC situation here, mainly because I don't know all the details and know enough people that do that I stand a good chance of being shot down very rapidly. The biggest problem as I see it is not so much the loss of specific projects (which admittedly for those involved is devestating: imagine being told that your passion for the last 3 years isn't funded so go do something else) but the long lasting damage to our credibility as a scientific nation.

I'm not a big fan of patriotism and its ilk, I consider it a useless if not damaging passion, but I will say that when it comes to large scale projects (some of these projects are huge for example X-fel has 71 universities and institutes listed for authors of its Technical Design Report*) you need to maintain national credibility. It is this national credibility that the UK risks losing by letting down the partners of the 26 projects that we are withdrawing from. Countries won't collaborate with us if they think that we'll cut funding 3 years down the line and that means fewer projects that UK physicists will be able to work on. Ultimately if there is less world-class work for UK physicists they will move to where there is work, either the US (which openly has said they want to import 'the best minds'), within Europe (the support for science in Germany and France is pretty huge) or even further abroad (Japan spends nearly 3% of its GDP on science). Currently the UK has an amazing position scientifically within the global community but we can lose it and then to regain it is a huge cost that I doubt we'll be able to afford, especially when 40% of our GVA follows.

*Incidently x-fel is the project that my PhD work is for and is one of the projects whose central, STFC, funding was cut, luckily this didn't involve the removal of my PhD funding as my university is directly involved with x-fel rather than via the STFC

Romanticism 2.0

2010-03-09T05:06:00.000-08:00

This post was inspired by an advert, I tend to try and ignore adverts as they have a habit of making me angry this one was exceptional only in the amount of anger produced. The new diesel advertising campaign (seen here on diesel.com or here for the ads themselves on million looks) is simple "Smart does X stupid does Y. Be stupid" (eg "Smart critiques, stupid creates") this annoys me no end. Partly it is because I consider myself smart and like to think of myself as creative but mainly because of the message: "being smart doesn't achieve anything so don't bother, just act on impulse and you'll be wonderful". This is the romantic philosophy writ large and in neon: reject rationalism, thought and technology in order to embrace spontaneity, passion and living as a "noble savage".

There are many things wrong with this not least in that by being smart you don't have to stop being spontaneous or passionate (just think about the typical mad-scientist: there are people like this). While the romantic movement has been gone for a long time it's children are apparently making a huge effort to come back. If it's not Prince Charles saying something stupid (“I was accused once of being the enemy of the Enlightenment, I felt proud of that” via The Times), Diesel adverts (diesel.com), its the Government sacking people for doing their job (ie being a scientist, via the BBC) or even more simply the rise and rise of woo (homeopathy, or chiropractic for your headache, they're ancient traditions and natural you know!).

There seems to be a growing feeling in the public that intellectuals live in ivory towers and don't connect with 'real' people or their concerns, leaving aside the fact that we are 'real' people with 'real' concerns, we need to combat this. This is not even about bringing science to the masses (itself a concept that is likely to reinforce the ivory tower idea). It's about removing the idea of the geek, the expert and the specialist. In this age of information anyone can be an expert or a specialist (google 'health care' and look at all the so-called "experts"). Just as with all other industries why should academia expect to not have to change its business model with the new age we live in?

We need to move from being repositories of knowledge to gatherers, disseminators and educators on evidence. This is a very important distinction: we need to help lobby, educate and aid people in understanding the evidence that we supply, that they can now access, not just tell them that we have it and that it tells us X. This isn't just limited to science, it needs to encompass everything. People need to be reminded that the geeks, experts, specialists and techies are real people too; that we share their concerns and that we are not people to be feared (or looked down on for having no 'expierence', 'connection to reality' or 'common sense') we are people. People with jobs and hobbies and lives. We just also happen to be the people who gather and interpret evidence for a job: just like everyone does all the time.

This is the only way we can stop the rising strength of 'Romanticism 2.0': by bringing ourselves back into the fold; by being human again. The alternative is that "intuition", or as it should be known "belief and superstition", will win and we'll all be worse off for it.

Today's game: don't annoy CPS; why the twitter-bomb-hoax means I can't say much

2010-03-02T05:03:00.000-08:00

Well some of you may be pleased to know I can't really talk about much any more. The reason? well, as explained in this excellent article from JackOfKent in his new bad law column the trial (BBC summary) of Paul Chambers is set to close soon. He's being convicted for posting the following on twitter:

"Crap! Robin Hood Airport is closed. You've got a week... otherwise I'm blowing the airport sky high!"

Now the important part of this is that CPS is not prosecuting him for making a false bomb threat (they admit that there isn't enough evidence that he intended to cause a panic by this) so instead they pressing charges of

"Improper use of public electronic communications network"

Which is an offence for anyone who:

sends by means of a public electronic communications network a message or other matter that is grossly offensive or of an indecent, obscene or menacing character;

As the Bad Law column points out this law was intended to stop nuisance callers and their ilk; not to mop up people that have mentioned the word bomb but aren't making a threat.

Now why this concerns me is that while the tweet concerned is threatening, it is still obviously a joke (which is why Paul is not being prosecuted for making bomb threats), so at what point does something stop being a joke and start being threatening (or 'menacing' as the law states)? The following statements are all the latter but are here as examples:

"It would be so easy to inject heavy metals into the air conditioning units at Heathrow poisoning everyone"

or:

"Anthrax is a terrorist's dream substance, it looks just like talcum powder"

Now using the CPS's logic if I now go to an airport (or other public place such as the university I'm currently sitting in) this constitutes a threat. These two statements could just as easily be from a security discussion as threats and while they would have to be taken out of their current context to constitute threats I think it is fairly obvious that this is what has already happened Paul's case.

In fact this could have happened to me recently: I had a trip to Hamburg for a meeting, running late in I put on the first t-shirt to hand before leaving, this t-shirt in fact:

for most of the day I had a coat and hoody but during the inevitable security check I had take them both off which of course revealed my horribly inflammatory t-shirt to a security guard who promptly told me off and that I could get in trouble if I wasn't careful. I didn't realise how close to real trouble I had come, given how the CPS have treated this case I doubt they'd struggle to find some law that made my t-shirt wearing chargeable.

This is a sad case, its set to make a criminal of someone who was understandably frustrated and said something stupid. It shouldn't have escalated at all, let alone to the point where they may set new precedent that anything said electronically while near a possible bomb target (ie anywhere public) no matter what the intention behind it can be treated and charged as a threat.

Update!

2010-01-24T10:33:00.001-08:00

For anyone who's been wondering where my blog has gone its currently on hiatus due to me having exams soon, for this I have been trying to type up 60+ hours of standard model notes into LaTeX. I've currently produced about 120 pages and I still have many more to go.

Normal service will resume in about 2 weeks time when I will spam out the (currently) 6 blog posts that I have noted that I want to write.

If people are interested and I get the OK from the lecturer I will also post up the notes for anyone that might be interested but as they're his notes that I'm writing up I will get the OK first

Busy

2010-01-15T11:06:00.001-08:00

Hey reader (who ever you are)

Sorry there haven't been any updates for a while, I've been keeping stuff going on twitter but at the moment I'm in exam season so not really able to post anything worth reading so I'm sitting on it until it goes stale or I can commit some time to writing

Sorry

There should be something up with in a few weeks (hopefully before)

Thought/rant for the day: "Isn't that odd" or when your just not thinking

2010-01-11T12:09:00.000-08:00

I have acquired a new pet peeve: the rhetorical question "isn't that odd?". My peeve is not with the question: things that are odd should be remarked upon and investigated. It is the latter part of this that causes me the annoyance: that thing's aren't investigated.

Things that people remark "isn't that odd" to will be of one of two catagories: either something of at least passing interest (eg sun dogs or ice formations) or that is out of place ("I'm sure I put my keys here"), the cause of my irritation is that situations of the former do not provoke investigation. Often they won't even illicit 5 seconds of thought as to the possible origin of the subtle strangeness that triggered the observation. Why is this?

Why are we so blasé and jaded that upon being presented with something we don't understand or is strange we are more likely to dismiss it that give it even a moments thought? While this point has any number of reasonable answers I think it highlights something that is deeply wrong about how we approach the world we live in: we apparently don't think.

In one of my favourite books (Hitch-Hiker's Guide to the Galaxy) there is a point where Ford Prefect hypothesises that humans talk to exercise their jaws, he then adjusts this to the theory that by talking we stop our brains working. This should not be something we find funny.

I am not advocating full scientific investigation just a little more thought when using the the expression, if only as a form of mental exercise. I find that I feel much better when I walk home from university than when I get the bus. The reason for this is that on the bus I will read whilst when I walk I will think (in fact this post was born on the walk home today). Letting my mind wander as I walk presents me with many little puzzles that I love to work out eg. why is that when I bus I people watch while on my walk I am not offered this luxury? Because on the bus I pass people but when I walk I don't. I could list many other realisations that I have experienced but most of them, like this one are utterly boring. Why then do I encourage it?

It may seem a daft point but firstly because its relaxing, the act of walking is relaxing but so is the act of finding small problems and solving them: teasing apart the situation based on what you know and what you've observed gives an amazing feeling of accomplishment (this is especially nice when the day has yielded few results). The second reason why I would encourage you all to pause after uttering or hearing uttered the phrase "isn't that odd?" that occasionally you will discover something profound.

NB. While writing this I had to work hard not to get distracted by sun dogs or ice formations, these are subjects that I have read about before and even then the lure of re-reading and investigating them was strong (yes there is also an ironic confirmation bias in my selection of topics that interest me as examples here).

Anyway I'm done with my thought for the day, to those of you who made it this far: well done!

Ten23: campaigning to get homoeopathy out of boots

2010-01-07T05:03:00.000-08:00

Ten23 is a new campaign in the UK working to raise awareness of homoeopathic products, firstly that they don't work and secondly how they waste time, money and can prevent people seeking genuine medical advice when they should.

I won't go through the reasons that homoeopathy doesn't work, there's a wonderful explanation here so go read it. Simply put it's water. You spend a lot of money for a bottle of water.

Ten23 work to raise public awareness that it doesn't work and is a waste of money, they have an open letter to boots asking them to remove homoeopathic "treatments" from their shelves as they are a trusted pharmacist that many will go to as a first line of treatment, using homoeopathic remedies can put these people at risk and they will likely assume that boots, being a trusted party, will have their best interests at heart: stocking only treatments that work.

Talking of worthwhile campaigns this is another: Libel reform which is working to revise the libel laws in the UK. To reduce their cost and make them less plaintiff friendly (which is so bad that the UK experiences "libel tourism": people visiting the UK to sue others). The state of UK libel laws is so bad that they are putting journalists at risk of being sued for investigative journalism (see trifigua or Simon Singh).

Please sign both these petitions, they are important and without acting on them we put health and freedoms at risk.

Religion: why is it privileged?

2010-01-06T10:21:00.000-08:00

There is a recent news piece on the BHA about the Department for Communities and Local Government's (CLG) recent creation of "faith advisors" this really annoys me.

Why does this annoy me? because there is a persistent rumour that we should give a damn what various religious leaders think. Having a religion does not give you special insight into anything. Being a priest to a religion does not give you extra useful knowledge. In fact what little insight it gives you will most likely be through a haze of out-dated rules and laws set down in a completely different time.

There are many community leaders, priests are just one example. If we're giving priests a special position within government (as advisers) why not scout masters? The argument that many people base a large portion of their life around their religion is normally trotted out at this point and I would like to take that trotting target and shoot it down now.

Apparently 66% of the population of the UK have no connection at all with a Church and I would be surprised if the number who genuinely shape their life by it is anywhere near that. People base their morals and tastes on those around them. This is part of what's called "social contract" essentially it is "I won't kill you because you might kill me first".

The religious already have a voice, it's called a vote. In a democratic society that is the only voice they or anyone else deserves. Other experts advise within a narrow realm that is defined specifically by their expertise. These "faith advisers" are going to advice on "economy, parenting, achieving social justice and tackling climate change" or the "big issues". Of all the groups in existence those that follow a religion are rarely the same that I would want to tell me how we can solve the complex problem of reducing green houses gasses against everyone's desire to produce them. They may have a "unique insight" but I don't consider praying for salvation a useful input.

If these people have genuine contributions to make from a standpoint of actual knowledge fair enough but some empty headed assumption that they connect with the people (that minority of 34% or less) and that this connection is somehow special beyond that of just grabbing someone from the street is bollocks.

This is not a post advocating the insertion of a humanist or atheist onto this panel it is advocating the removal of this panel, if you want the advice of community leaders ask them with reference to a specific situation. 13 advisers is too few to cover even a fraction of the many, many, many facets of life in the UK that they will need to in order to garner useful opinions on the topics they want. Will there be a Scientologist? how about a 18 year old street preacher from Brixton? or an anarchist Humanist? Faith may be a major point in a lot of people's life but given the department concerned I think they would be better served looking for representatives of specific socio-economic groups. not faiths.

NB the 66% figure is from this page here: http://www.vexen.co.uk/UK/religion.html

Fun stuff

2010-01-06T04:52:00.000-08:00

This sort of post will turn up from time to time - mainly when I should be doing something else and as I have a problem paper due it seemed like a good time to start it.

Some of you may have noticed the new little toy to the right - its the Transport Chaos-o-meter, using TFL, National Rail and traffic reports it guesses how much chaos is being caused to public transport at the moment. Today with snow its in pandemonium mode. The full info on it can be found here.

Next up are two faux news papers newsBiscuit and The Daily Mash.

So there's a bit of fun I should get back to work....

Firefox woes...

2010-01-05T08:36:00.000-08:00

This is will be a pretty brief post. I have recently been having trouble with certain websites not fully loading, mainly webpages with dynamic content (eg facebook or twitter) it turns out this was because I was running an older version of JAVA, having now updated to 6.17 it seems to have fixed the problem

SO if you find that certain webpages in firefox will not load or never finish loading try going to
www.java.com and check that you have the latest version installed.

I hope that helps someone

What to expect: Blogs I read and stuff that has made me laugh

2010-01-04T06:30:00.000-08:00

As this is a new blog I thought it would be useful to post up a list of some blogs and news feeds I read and like, as there are quite a lot this will be a brief list but it should give you some idea of what it is I will be mainly be writing about.

Here goes, first up the non-standard news (ie not the bbc):
Slashdot.org - Geek news basically
Lifehacker.com - useful stuff of all types (Gadget reviews to how to find north with a watch)
BHA - The British Humanist Association - I am a humanist, skeptic, and atheist I will try not to rant too much about religion (especially those of a dogmatic bent) but I promise nothing
Singularity hub - A website about cutting edge technology that is likely to aid the singularity or to do with transhumanism etc.

Actual Blogs:
Pharyngula - 'Militant' Atheist blogger PZ Myer's home, apparently one of the most read blogs on the net
Blag Hag - a US girl who posts on Athiesm, University life and general life.
Charlie's Diary - Charles Stross's blog - if you haven't read any of his Sci-Fi then go out, buy some and read it now (favourites of mine are 'Accelerando' and 'Halting State')
Jack of Kent - A UK Blogger who covers legal matters very well and is a key figure in the Simon Singh Libel movement
Spoonblog - Blog of artist Paul Duffield who draws Freak Angels as well as drawing an awesome (free) comic he posts up many interesting titbits
Bad Science - Blog of Ben Goldacre, awesome skeptical blog that dissembles various bits of bad science from around the net
Respectful Insolence - Blog of a US cancer researcher and surgeon who goes by the name of Orac - another anti quackary blog

Interestingly enough I don't read many physics blogs, mainly because I've yet to find one: I tend to find blogs via other blogs - if I searched for them I would have far too many too quickly. Also working in physics its something I am not as likely to blog about - tech and science in general but less physics.

Anyway that is a sample of things that I am likely to link to or post from or comment about so enjoy.

it also doubles as a reminder of who I'm following should I lose my feeds...

Beginning of the end; or how the election campaign was started

2010-01-04T04:59:00.000-08:00

Right first actual post. I've had a fun morning, suffering from jet lag means I'm actually inhabiting a normal sleep pattern for the moment so I was up early enough to see the un-official start of this years UK government election campaigns.

It would appear that Labour spent their Christmas trying to figure out how much the Torys want to spend, while the Torys spent it coming up with ways of changing the NHS. I'm not sure which route will score them the most points in the end but I think Labour will edge ahead on this one.

I think this for several reasons: reporting that there is a £34bn hole in the Tory's plan will be a hard idea to budge, a lot of what the Torys are saying about the NHS will be old hat to most voters and Labour have cunningly left the Torys little to attack in return.

Hole's in their accounts seem to be a running theme for the Torys: all parties use it as a standard cheap stab "how are you going to pay for X" but it seems to often cause the Torys the most problems. In addition ringfencing the NHS will be hard to achieve, even without spending more on it above inflation it accounts for a huge proportion of the yearly budget.

The points the Torys have made about the NHS will sound good but I think a lot of the will suffer from being a secondary worry to the economy and cuts in general. When Labour took power they did so by highlighting what were major problems in the NHS of the time, trying the same trick when Labour have managed to deal with a lot of the problems facing the NHS will be a hard to pull (there are problems but saying that league tables are a poor measure isn't like saying that people wait up to 10 hours in A&E which was the case when the Torys lost).

As for leaving the Torys little to attack I hope Labour will hold off publishing a manifesto for a while. If nothing else it will damage politics in the UK to have a 5 month election campaign as it will be boring and kill debate.

Of course if the Torys are cunning they may be able to turn this about and use the early attack by Labour to unfoot them and then set the pace with their manifesto, drafts of which they are cunningly publishing over the next few months.

Anyway that was pretty boring but engaged me for the morning so enjoy!

First Post AKA what this blog is about

2010-01-04T03:37:00.000-08:00

G'day

This is the Blog of Sam Cook. I am a particle physics PhD student based in London, I started in September last year (2009) and I'm loving it. I play too many games (board games, computer games, drinking games what ever really). I spend pretty much all of my time either on a computer, eating or sleeping; yes I am a geek (probably a even a nerd).

The purpose of the blog is that it's somewhere for me to write; mainly on things that annoy me but sometimes on things I like as well. As a physicist I spend a lot of my time writing code so this will hopefully mean that in 2 years time when I have to write a book (my Thesis) I may actually still know how to form a sentence, it also aids me in not getting killed by my friends/flat mates/people in the street for ranting at them too much.

Anyway I hope that has bored you because it's bored the hell out of me and I actually want to post up something a bit more interesting.

So on to the actual blog!

The equation of Creation

2009-12-12T09:51:00.000-08:00

This is a link on the so called "Equation of Creation" purportedly linking the Hydrogen Fine Transmission line (Hlf), Pi and the speed of light (measured in 'Thoms') to some strange "Omega Constant" (0.0123456789). This is the equation:

Hlf.π/Ω = C

For the rest of this post I'm going to attempt to disassemble the paper defending this equation.

The main thing that sticks out in reading this paper is that the author seems determined to prove he can do multiplication, it is littered with "if you multiply a by b you get c" I'm not sure if this is an attempt to sound scientific or what but its very irritating show's nothing.

Anyway onto the 'science': I'm going to work through this section by section skipping over a lot of stuff but trying to pick out the main points.

The paper starts out with some odd justification of "I'm a scientist and even I believe it" kind and then goes on to justification of the use of Hlf, as you can see from the wiki link yes this is an important frequency. Light at the Hlf frequency will penetrate interstellar dust etc yes SETI search on it (along with many other frequencies) so what there are lots of frequencies that are searched for all sorts of reasons. Hlf has some half hearted justification that if you wanted to send a message to humanity you would use a frequency that we are looking on but that's about it. The justification for the inclusion of pi is that it has been suggested that Intelligent life might transmit at a frequency of pi*Hlf as there are no natural sources at this frequency and pi is a number that almost any advanced civilisation should recognise.

My first major issue with this is omega, this is an arbitrary number, 1/81 is roughly the ratio of masses of the Earth to the Moon

5.9736*10^24 Kg - Earth
7.3477*10^22 Kg - Moon
R = 81.298
1/R = 0.012300425594

but not anywhere near acurately enough to justify 10 significant figures and the claim that 0.0123456789 is attached to the Earth and the Moon, it just isn't. Additionally what is the obsession with 10 significant figures with all measurements, apparently other than this one. Having 10 significant figures on your estimate if you can only measure to 5.

The next section "Where is the science?" contains one of the more comic statements, apparently π/Ω gives a value in milliThoms, reading ahead a thom is also known as a megalithic yard. now fogive me but pi is a ratio, omega is an arbitrary number possibly a ratio of masses either way a ratio of ratios is just another number, not a distance.

Now while a frequency multiplied with a wavelength gives a speed I've yet to see any evidence that we have a wavelength with which to multiply. Anyway the rest of this section is mainly "wow our numbers give us the speed of light in an arbitrary unit how cool is that?!" as well as pointing out that this value of the Thom scales the hydrogen line to the speed of light, well whoop you can solve an equation!

Next section the mysterious 'Thom' is explained: originally it started out as a unit used in stone circles, the fact that a length that is roughly one standard human's pace was used throughout many many stone circles isn't that amazing is it? If I had the time (maybe later) I would see how accurate this number is, given that 0.8297 gives us fractions of millimetres I will be VERY surprised to see if there is evidence for this.

Anyway there is an "exact" method to calculate the Thom so don't worry - it's 1/366th of the transit of Venus across the horizon. This section finishes with how it turns Atheists into Creationists and other such voodoo as well as how there is still more! yes, the Thom relates the circumferences of the Sun, Earth and Moon!

To relate the circumferences you multiply the full value of the Thom (0.829417864 metres) by some number (to get a second arc), then 360 (to get an degree arc) then finally by 366 to get the full circle. Now this is the first actual error I've found, but I'm pretty certain there are 360 degrees to a full circle as well as 360 arc seconds to a degree. For example using 366 Thoms to get a second then 360 and 366 to get the full circle you get 39,997.98kms, not bad given the Earth circumference is between 40,000kms and 40,008kms, using the standard number of degrees in a circle you get 39,342Kms not so good given that any number has been used. Further examples and their accuracy are given for the Moon and the Sun.

Using arbitrary numbers to get reasonably close to an actual number is not much of a skill or much of a challenge, especially when you are moving from values of an order 1 to order hundreds of thousands. The claim that:

As a side note, the values 100 and 40,000 used above in calculations of circumference, are not arbitrary numbers, but are very significant values in the large volume of research about the message embedded in the characteristics of the Solar system

is rubbish as well - until I see that evidence they are arbitrary numbers that help you get close to your goal value.

So what have we seen? Basically it is very easy to pick arbitrary numbers and make them look roughly like other numbers. For this to be evidence of a Creator I would expect much better than 99.9% accuracy especially given the very odd selection of units and mangled maths. As well as this complaint this whole paper has two massive errors: firstly the claim that π/Ω gives a length, unless you show me what Ω measures I will think of it as a number and nothing more, secondly in the proofs that the Thomis an exact proportion of the circumference of the Moon, Sun and Earth there are only 360 degrees in a circle.

As a final point below is the "proof" that my finger made the moon as I can use the length of my finger as a starting point for maths that calculates the Moon's surface area. This proof took about 5 minutes.

eg 8*8*16*365*100 = 37,000,000Km² the surface area of the Moon, 8 is the length of my finger (in cm), 16 is the average male age for puberty and 365 is the length of a year 100 is a special number we have evidence for.

Libel reform

2009-12-11T02:51:00.000-08:00

This (should) be a quick post, for those of you who haven't seen there is a new website that I think you should all go an look at:
http://libelreform.org
it is a lobbying group that aims to improve the way libel cases are dealt with in the UK, have a read about on it have a look here for Ben Goldacre's info on it (he's one of the founders).

If you live in the UK and in any way care about science this is important, if you live elsewhere and care about science its important. If you don't care about science you should and then this is important.

Essentially our current libel laws are crap. The cost of libel in the UK is about 170 times that of mainland Europe, and the burden of proof is upon the defendant: ie when someone sues you for libel you are guilty until proven innocent.

For better (and probably correct) arguments about why you should give a fig about libel laws look around on the libel reform page as well as Ben Goldacre's blog or Jack of Kent's blog or just read up on what's happening to Simon Singh.

Please look at it and come to your own decision; this is important.

Link dump

2009-11-25T14:02:00.000-08:00

hey guys (well ok guy)

here are a couple of links that I think people should read firstly:

911.wikileaks.org - transcript of 500million (I think) pager messages sent in the 24 hours surrounding 9/11 from the DC and NY areas

As a follow up to one of my earliest posts there is this report in the Guardian with the full report here.

Finally another follow up (of sorts) to this: there is a list here of "8 awesome cases of vigilantism".

The first I think was one of the most poignant things I have read in years and I'll say no more about it. I want to put up a blog posting as to my thoughts on it but at the moment im too tired and they're too conflicted so it'll happen another day - maybe.

The second was mainly for historic purposes and that it interests me.

The last is the one (surprise surprise ) that is most worrying. Aside from the standard "anonymous did it" fallacy (seriously guys the hint is in the name they're not organised they're anarchists even if they don't know it) it is a little worrying the pure psychological terror that the internet can aim at someone. Yes the people in this piece at least deserved something; but not the ire of 4chan.

Having watched the swell of a 4chan mob against someone its a sight to wonder at as well as flee from.

I wonder how many more people will find this out the bad way?

This is just cool

2009-11-23T12:09:00.000-08:00

Howdy net!

This is going to be a very short post as I'm currently struggling to keep my eyes open (hooray for 12 hour day with 4 hours on public transport)

so I'll just leave you all with some awesome pictures

pretty pictures!

THE LHC HAS DATA!

Seriously cool stuff - they should be slowly stepping up the power over the next few months.

the FUD is coming! the FUD....

2009-11-19T08:23:00.000-08:00

This is a quick post. I don't want it to be but currently I can't quite form up a good post about it (needs some work me thinks)

So until I get round to writing a post on it here's an interesting link.

Personally I think its FUD (fear, uncertainty and doubt) but it holds the promise of some interesting impending debates about the internet as well as some big problems if it does go through as written.

Step-hen free speaks!

2009-11-15T05:49:00.000-08:00

This is more so that I can find it later but I recommend watching this:

What has the Particle Physics ever done for us?

2009-11-15T04:50:00.000-08:00

Other than this? i.e. the internet.

While the LHC may not be about to give you a new version of the microwave a lot of the 'spin-off' tech is VERY useful (HTML, radiation imaging for medicine, modeling systems used in finance etc click here for more). More direct uses are common as well this is a report from CERN on a new experiment that's just starting up to look at how cosmic rays may affect cloud formation and climate change. There are also experiments being designed that will create x-ray lasers (XFEL, LCLS and one in japan who's name I forget)use linear electron accelerators, to create x-ray lasers that will allow us to probe matter at even deeper levels: being able to image the absorption of chemicals into a cell, for example.

Anyway that's it - just a micro-rant on "what have the particle physicists ever done for us?"

It may be a religious view but that doesn't mean you can use it to investigate

2009-11-14T12:05:00.000-08:00

This is a somewhat depressing story, I don't have the full details but going on what's in this report the guy was sacked for believing that pyschics should be used to investigate crime. Fine by me, believe what you want; but if you try and follow through on that then expect to get sacked, psychic evidence is not permissible in court and should not be used as a resource.

If the guy was sacked for merely stating his opinion that psychics should be used then he's being persecuted, he's an idiot for suggesting it but he's allowed to voice such an opinion. If he tried to use or pushed for psychics to be used then its another matter.

Ah well

What's more irritating is this, again it's a case of not know enough: either the police force were (hopefully) following up the tip to reassure the family and on the off chance that a real tip was being obscured as pschic, or they actually wasted time and money on a psychic tip off. That being said it should have been obvious after finding no petrol in the guy that the tip off was rubbish

ah well

The burning stupid

2009-11-06T04:09:00.000-08:00

This really hurts my brain. To suggest that being secular is what has caused the reduction in the number of births and overall family size is stupid. To quote a parliamentary report I found:

"The number of births in the UK has declined throughout the
century [1901 to 2001], interrupted only by the two post-war ‘baby booms’ and
a secondary peak in the 1960s. " [1]

Unfortunately I can't find any information about relative percentages of secularism to any form of religion other than in 2001 when only 15.5% [2] identified themselves as having "no religion (inc Jedis)". Now this strikes me as not really a reasonable way of accounting for the massive drop in birth rates over the last century:

"Between 1901 and 1905 the general fertility rate in the UK was
about 110 live births per 1000 women aged 15-44. By 1971 this
had fallen to 91 and in 1997 to 597." [1]

Call me scientific but might it just be that the number of people surviving birth has increased: 140 infant deaths per 1,000 births in 1900 to 5.4 per 1,000 in 1997. With more people surviving birth you don't need as many children, life expectancy has also increased (75 for boys, 80 for girls in 1999 compared to 45 and 49 respectively in 1901). A longer life expectancy reduces the pressure to have children at a young age, or at all.

Anyway, moving on from the stupid argument my main interest is this: over the last year what happened? maybe I'm being more focused in my reading but the number of public figures (Tony Blair for example) basically slagging off those who take a humanist or secular world view has seemingly massively increased.

As a standard test: re-read what Lord Sacks said but substitute the word 'muslim', 'black' or 'gay' where he says "neo-Darwinists". Not sure a bastion of great "interfaith relations" is he now?

Gripe the second: WHAT THE HELL is a neo-darwinist with respect to religion? They have nothing to do with eachother unless you happen to be some knuckle-dragging idiot. If anyone out there seriously thinks that secularists or humanists work from any sort of Darwinian principle they are utterly mistaken. We just don't believe in God. Evolution is an utterly seperate argument and the continued muddling of the two is stupid.

Repeat after me: "Evolution, The Big-Bang, Cosmology, Chemistry, Geology have NOTHING to do with the fact that I don't believe in any deity". They may both come from the fact that I think about things and draw what I think to be rational conclusions but one does not cause the other.

mmmmm retinal projection...

2009-11-05T04:58:00.000-08:00

This is insanely cool. Near real time translations subtitled and beamed onto your retina. Who doesn't want one? while I get the impression this will (initially) be like the voice recognition software of the late 90's (ie requires a fair bit of work for 50/50 results) it has several features that are very significant.

The actual translation system is the not too surprising amalgamation of voice recognition and translation software. While both these technologies have been around in vague forms for the last 10 or so years it has only been in the last 5 years that they have become truly viable. Voice recognition interfaces are pretty common now on dial in services (eg for national rail) and while they do get it wrong from time to time they are pretty good. The same goes for translation, most things can be translated by, for example, google translate; it may have some interesting turns of phrase but the fundamental message gets through and this is a free, web-based tool.

The most exciting feature of this though is the retinal projection, this is something that has been slowly emerging of the last year or so (either as micro screens or direct projection) and is one of the last technologies needed to achieve complete augmented reality. We nearly have complete internet data coverage (it may not be fast but there are fewer and fewer places where I can't get some sort of net) and with technologies like 4G, BT openWorld (all BT customers can jump onto free open net connections from BT) or the cloud all poised to become very common it shouldn't be too long before people are wondering how they coped without being able to access wikipedia while walking down a street.

Augmented reality is a while off yet (and still limited by battery life) but as more technologies start to use it (see the phone app layers) it is fast becoming reality. I would say that within the next 10 years at the latest people will have augmented reality headsets (most likely glasses) and that they will be common within 15 years. As a technology I suspect that it will be similar to voice recognition in that for the next year or so everyone will be claiming to use it with no actual utility. After that, and especially with things like the translator specs, it will start to re-emerge as general utility, to steal an idea from Charles Stross: wouldn't it be cool to have a map of the city your in over-laid on your vision and then be able to watch the progress of your bus towards you?

This is, I think, the most significant part of these glasses: not so much what they can do (which is very cool) but that they represent a protrusion of what so far as been a fun toy in labs into useful utility.

Smoking up a storm

2009-10-31T05:52:00.000-07:00

yes ok I'll stop with the bad titles, this is the last one, maybe.

On to the actual purpose of this post: it appears that the government of our dear island has sacked Prof. Nutt from the Advisory Council on the Misuse of Drugs (ACMD). The reason? saying that by changing the classification of drugs to "scare" people from them you were "devaluing" the evidence. The BBC report on the sacking can be read here and the report on his comments here.

My main gripe with this is the lack of respect that politicians (of all parties) seem to have for the people who advise them. If you are employed to offer advice on a policy your agreement with that policy shouldn't be a contingent of your employment.

In this case I think that the Prof. Nutt has a very good point: we allow the use of alcohol and tobacco (which can cause, among other, things cancer and cirrhosis) but ban the use of cannabis (a chance of developing psychosis or other neurological problems).

Moving on from this to a more general outlook this seems to highlight one of the main problems currently experienced by the scientific community: our expert advice (a few dozen years studying a small field) is routinely being over thrown based on 'gut-instinct' and anecdotes. There is a distinct distrust at all levels of society of those with expertise. This would be less worrying if it wasn't for the fact that often this expertise is replaced by much more dubious sources of information: how many people now will take the advice of someone who uses 20 minutes at the university of google to discover that vaccines are bad over someone who has spent a greater portion of their life researching and studying exactly how vaccines work.

I think this is more than just a new anti-intellectualism (which it is), I think it's the beginning of global future-shock. As technology and knowledge moves on people are becoming increasing terrified by the change and looking for simpler explanations of how the world works. The continued inability of science to do what people expect of it (why do we still have AIDS why isn't my car flying yet) has given people the impression that as a group scientists are detached from the concerns of pretty much everyone else.

This leads me back to the reports on the BBC: people no longer want experts. They don't want people who are willing to tell them that we don't have all the answers yet, to tell them that actually drug abuse is endemic in pretty much all societies and has been for years. People are actually losing a lot of the rationality that drove us to where we are now. I'm not saying that we are going to back-slide, just that we might move sideways a bit. As this century progresses the number of new technologies in people's lives will drive many to consider it magic. People won't want to be told that the nanotech injection they just received is very carefully molded to them specifically they will want to just know that the magic juice will cure their cancer.

Science has raised us so much higher than we have ever been before and now most people cannot see the difference between it and magic. It's a shame but for many people I think that the 21st century will be one of magic and will miss out on the wonder that we can create.

how habitable is the earth?

The rise of journal sharing?

2009-10-29T08:34:00.000-07:00

There is a very interesting (and short paper) on the impact of and ease of illegal sharing of journal articles here.

For those of the tl;dr (too long didn't read) variety basically a large number of journals that practice closed access (you have to pay to read articles) are having their articles shared via websites etc. The estimated cost of one of these websites to the 2,000 odd journals whose articles were republished as $1.4Million (based on $30.00 per article).

I'm not a big fan of intellectual property (IP) laws (maybe because I have nothing to protect) but I feel that several things have come into play in recent years. The IP laws are now as likely to protect large companies from individuals as the opposite (in fact more likely as an individual will rarely have the resources to cover legal costs) and the rise of the internet which has blurred the line of what can actually be protected. Is code something that you can patent? that particular bit of code or the concept behind it. These issues have already been met by firstly music, then movies and now slowly the publishing world (look at the trouble google is having with news that they license and various books).

In the case of scientific publishing the real question is whether we should pay for information. Prior to the internet a lot of the work of publishers was exactly that: editing and publishing articles that would then be bound together and sent to those who were interested often costing a lot of money in the process. Now in the publishing world most of the work is done electronically, editing and organisation of the information is still important but the cost of actually printing the article is often no longer an issues as people will read the papers online. Should we then be paying up to $30 for an article?

I don't think we should. Information is at its best when everyone can access it, creating a situation in which multiple people can all review and learn from someone's contribution is far preferable to creating an arbitrary barrier for people to cross. This is especially true in the case of the sciences where people are interested but only a very minor percentage will want to pay up to $100 for a paper that they're only interested in browsing. The upshot of charging people to learn is that you create a capitalist market for information. On the internet this means that people will go where it's freely available (eg wikipedia) or where it's free but wrong (eg Answers in Genesis). As part of the purpose of science is the propagation of knowledge forcing people to pay to get good information seems counter-intuitive. This is more of a problem now when information is so freely available in general and people are treating science more and more like magic: either something to be feared or avoided as un-knowable. Giving good and easy access to genuine science will mean that those who are interested can get hold of the actual information that is needed and make their own mind up about it. I'm not saying this will stop websites like Age of autism from spreading misinformation but with access to genuine papers on vaccines or the LHC people who might otherwise take these websites at face value (especially when presented with the scientific world hiding its information behind a pay wall) they may read up and find out the real facts.

While this is a very similar situation to the one found in the entertainment industry I think the subtle differences make the case stronger for open access journals. While the entertainment industry should be free in some form (I pay for the cinema and yet still insists on adverts why!?) funded through pay-to-dodge ads or a pay-to-own system etc. The journals system should be completely free, a lot of journals already have adverts if these moved onto their websites in a "pay for the ad free premium version" system I would be more than happy.

"It's only a theory"

2009-10-14T17:32:00.000-07:00

Interesting program on BBC iPlayer called "It's only a theory" hosted by Andy Hamilton and Reginald D Hunter, first episode has a very interesting man on talking about the possibility that the first 1,000 year old person has probably already been born. Seems to be a reasonable argument based on bell curve concepts.

The idea is that people being born now will likely have access to technology that will extend their life significantly and once they get old (again) the process will repeat to the point that essentially life will be sustained ad finatum.

The guy presenting the argument is awesome (HUGE beard) bit of a strange program not too well created, interesting idea with a reasonable approach to science but somewhat trying to hard for jokes that aren't really there.

Further VHDL adventures

2009-10-07T14:20:00.000-07:00

Well I've finally made my shiny toy do something vaguely useful. With the amazing power of science (and several weeks hard work/hackery of other's code) I've made my board into an 8-bit binary to hexdecimal converter. It does this by changing the output of the seven-segment LED display to the relevant character based on the position of the 8 sliders.

That's about it. Next stop something genuinely useful.

First week

2009-09-30T12:52:00.000-07:00

Well half way through my first week as a PhD (well technically MPhil) student and what have I learnt? Mainly that PhDs HURT I've spent the last 2 days trying to cram the better part of a terms worth of electronics (well logic mainly) into my brain. Doing fairly well so far.

I have also learnt that there are far too many annoying webmail systems that don't sync with stuff properly also that the new Microsoft Outlook live sucks utter balls.

anyway that's all I have to report at the moment (yes this was a worthless post but no one reads this so sod it).

will maybe post something more substantial soon when I think of it.

The obligatory late post

2009-09-23T11:43:00.000-07:00

Hello again! I'm back (well while I remember this anyway). Various things to report: firstly I'm heading into a PhD so back to uni very soon (which is just awesome!) Also in a new flat (that's my excuse for lack of posts anyway) and finally loving the iPhone - if you use the net a lot while on the go get one.

Anyway on to something slightly less egotistical: interesting developments. The main thing of interest to me at the moment has been the prospect of building a CNC Milling machine (basically a computer controlled router - the type for carving). This is a project between me and a friend and we're hoping to start on it very soon. This will mean I should have access to an amazing carving machine: essentially plug in the information for what you want to build and it will (so long as it can be carved from a block of whatever).

Other cool gubbins that has been circling is that I've recently finished Iain Bank's "Crow Road" this is an amazing book if quite sad. Well worth a read.

Anyway looks like I can't think of much else to post and I'm ready to install Dawn of War II so I'm off to enjoy that

New Comic

2009-08-11T07:55:00.000-07:00

Hey Guys,

I'm back again (briefly) to post a link to this a comic a friend of mine is drawing. Should be a good read once a week so take a look - only one up at the moment though so not too much to worry about.

In other news I'm still fighting with VHDL and my lazyness in trying to get my JAVA-fu going again. Will be posting up some more games reviews soon as well (mainly once I've got some second games down), I'm hoping to put up reviews for 'Race for the Galaxy' and 'Crunch' I've had a single game of RftG and a few of crunch and both are very good. As I'm off to a games club tomorrow I should hopefully have a few more games down to pass judgement on.

Lit-bots and Comp-scripts: how the world is getting faster...

2009-07-30T03:32:00.000-07:00

I saw this while on holiday published in the International Herald Tribune I was going to blog about it then decided not to becuase it was an isolated case, well I thought it was then I read this about half way down Ben describes this:

"Professional complaints followed in May, mostly about individual chiropractors’ claims. Then, in June, blogger Simon Perry found the BCA database of 1,029 members online, containing 400 website URLs. He wrote a quick computer program to automatically identify all the chiropractors in the UK claiming to treat colic, locate their local Trading Standards office, and report them (more than 500 in total) automatically, followed up with printed letters."

This made me look up. If you haven't read the links here is my main interest in these reasonable disparate stories: they both use simple bots within a legal framework to spam requests. Respectivly one spams buy orders (buy for 1cent more and get a lot of money) the other spams legal letters requests for investigation. This has been online for a while in the form of trawling take down letters, these are simple bots that look for things that may be copyrighted material posted illegally and then spam the ISP of the concerned website with cease and disist letters. My main interest in this is that this sort of thing will produce an arms race, already this is the case on the stock exchange where groups are trying to out do each other with faster systems and smarter algorithms, legally similar systems are likely to evolve: clouds of company bots that exist to absorb the flak of other's take down bots and simlar...

for more ideas read accelerando by charles stross

anyway just thought I'd flag that up as it interests me

DNA databases, Charlie and Ben

2009-07-18T15:20:00.000-07:00

This is going to be a pretty short post as there isn't much to add to this discussion other than what is said in these two reports: first Ben Goldacre on the bad evidence used to justify long term retention (ie 24 years retetion) of DNA data taken from those who are arrested but not convicted or cautioned. Second is this article by Charles Stross on the odds of being a false positive in a government database check (in this case CRB check and why he doesn't give school readings of his books).

The only thing really that I want to add to the debate on a database of our DNA etc run by the government is that the risk in terms of security of a database that will ultimately link ALL your information in one place if breached is pretty horrible. I'll briefly expand this: the DNA database would be likely allowed to expand (through ID cards etc) to cover everyone and be multi-use, ie your medical history would be there you NI number what ever. Even if this doesn't happen a single source of information would make identity theft a utterly crippling crime, especially as it would be most likely a random person who would be used to act as a patsy for someone else. Although this is less likely given the current technological state it is likely only a matter of time before the current DNA system starts leaking.

Adventures with VHDL part 1.

2009-07-15T07:44:00.000-07:00

Well I've finally got my arse in gear and started playing around with VHDL. I am subjecting myself to this for two reasons: 1) being able to program firmware is cool and useful as well being a reasonably rare skill 2) it's going to be useful for my PhD.

So what am I doing I hear you cry? Firstly I have been lent a very fun piece of kit: a Digilent NEXYS 2 board this is a programmable board with all sorts of ports and switches LEDs and similar to play with. Attaching it to my pc is a basic USB cable and then I have the Xilinx WebPack (a free download containing IDE and other useful programming gubbins). The final thing needed was the digilent program 'Adept' which allows you to upload your program via USB.

Armed with these I have ventured forwards into the world of chip programming.

So what have I learnt? thus far not much, I've got a basic program running that depending on the configuration of 4 switches the 7-segment display will give the number converted from binary into hexadecimal this was done by follow thing this fairly basic tutorial.

I learnt two major things: firstly check the EXACT setting of your card. I had a lot of issues in that I was getting a "device IDCODE conflict" error every time I tried to load the program on to the hardware this was because I had it set for the XC3S500E not the XC3S1200E in the 'Design properties' (right click the any of the files in the 'design' pane). The second thing I learnt was that to set the start up clock you need to right click 'Generate Programming File' in the process pane.

This sort of programming is interesting it that everything has two entries into your code: the first is called the entity which describes the number of inputs and outputs to a given structure; the second is the architecture that actually describes what is to be done with those inputs and outputs.

In my case the inputs are the switches and the outputs are the 7Seg display as well as anodes which switch of the bits of the display that I don't want (there are 4 separate 7seg displays I need only one).

The architecture is where the interesting programming happens (as far as I can tell) with '<=' directing inputs to outputs. In this case 'select' was used select a binary string for controlling the 7seg when a certain value was input via the switches (x0 through to xE). The anodes were all set manually via the line 'anodes <= "1110"; ' (remember that for this '1' is off '0' is on) this was done so that only the right most display was on.

On the entity side ports (inputs/outputs) were declared as a block of '3 downto 0' giving ports 3,2,1,0. each being declared "STD_LOGIC_VECTOR" which I assume defines the arithmetic to which it subscribes.

Finally once your .hdl file is finished you need to declare what physical ports everything attaches to. This is via a .ucf file that simply translates the port from the VHDL file to an actual port (in this case by looking up the number on the board itself).

Cool stuff

2009-07-15T07:04:00.000-07:00

Frstly: the Chap Olympiad, a very daft but fun event recently held in London here's a link to an ITN report on it.

Secondly: big news in engineering and opto-electronics (if it gets off the ground) scientists have set up 'circuits' such that light can be used to open and close gates. This is important as it means that fully controlable gates can be made either way here is the report.

Sorry about the lazy reporting feeling tired and working on a programming project. Will probably update some information on it soon

Update and first games review: 'War on Terror'

2009-07-12T02:57:00.000-07:00

I haven't posted for a while, mainly because I've been skimming the news (busy week because of new job) and not seen anything too interesting.

Anyway I'm going to try and instigate some interesting blog material which will be to do with the various games I've been playing. I have plans to play some D&D at some point soon so that will be going up here but today I'm going to write about 'War on terror' (WoT).

I can't review it fully as I've only played a 1v1 game and it requires a few more people for the full affect but what I have seen so far is very good, very very good in fact.

At its most basic level WoT is a souped up version of risk with elements of settlers of catan; from the risk side comes the global domination/war aspect and from the catan side comes the resource production/settlement building side. The basics are fairly simple: each go you can build or upgrade a certain number of settlements as determined by the action dice, these can only be built in countries adjoining your existing settlements. Once you've built all you want to you roll two dice and gather oil money from the countries with the corresponding number (these are hidden until you build upon that country). As well the building there are two decks of cards (empire and terrorist) and the terrorist counters. The decks allow you to attack other countries or terrorist groups as well as other actions (free builds etc). The terrorist groups can be bought by anyone and placed anywhere on the board but once they're on there they are usable by anyone, this means that your opponent can move them into your countries or anywhere else. There is one final rule which is that a random player will be made the 'evil empire' this allows you to draw cards from both empire and terrorist stacks giving you a greater range of options but also giving others a bonus for attacking you.

These three mechanics work very well together, the building is simple and quick, attacks can be resolved by rolling two dice (unlike risk's hundreds) and once someone goes out they can control the terrorists.

In terms of actual gameplay WoT is highly intuitive, fast paced and funny; a game can take quiet a while but no one gets left out because they lost early which is very nice. The balance of it makes the terrorists very powerful and a dangerous group to deploy. It will take at least a few goes to get the balance of cash right as you need to spend money to make money as well as defend or weaken oponents with terrorists keeping money in reserver is also vital as some of the terrorist cards demand that you pay a hefty ransom.

The other advantage that I have found with this game is because of how you start (only 4 teritories each for a 2 player game) you don't have to start in direct competition with someone (like risk) and that global position is not quiet as crippling as in risk (ie starting in Australia doesn't mean instant win for you).

Outside of gameplay the game is very nicely designed, colourful with lots of nice touches it is wonderful just to look through the cards and around the board for the tons of little comic touches.

Generally this is a game for a pretty much anyone it is a long game and it does require a bit of thought to play BUT that being said it is excellent fun and doesn't penalise people who go out early.

Nextgen screens.

2009-07-03T02:37:00.000-07:00

I've been recently reading 'Halting state' which is an amazing book by Charles Stross on the what will happen as the Internet becomes more and more ubiquitous. Among the technologies he uses in the plot is continuous Internet as a HUD (heads up display) this sort of HUD would be projected onto what you see from a pair of glasses giving you anything from the best route to your destination (think an iPhone whose screen you see all the time).

Most of this technology already exists (see the sixth sense prototype), iPhones supply constant GPS capabilities, 3G phone systems allow for some degree of Internet access almost anywhere (the newer 4G will improve this massively). Things like the cloud and the grid give constant wifi connections. MMORPGs (Massively-Multiplayer-Online-RolePlaying-Games like World of Warcraft) are becoming mainstream and as they become less esoteric and video games become a common media more MMORPGs will crop up. Urban gaming is already appearing with examples such as geocaching or the more paranoia inducing StreetWars.

In terms of non-existent technology only the ability to create overlays onto the real world are missing and this has moved a lot closer to reality with the creation of a .97" screen by the American company Kopin the big thing about this is that at less than an inch they have created a fully functioning 1280x1024 screen (that's the same resolution as a standard 19" monitor). While an inch screen sounds like the ultimate in eye-strain-o-vision at the distance of a glasses lens it is reasonable to view.

At most much of this technology will happen within the next 10 years or so, the full overlay technology may take a little longer but if nothing else we are now (pretty much) fully capable of hooking a good webcam to a pair of glasses and running the lens as screens. Of course what happens if someone hacks this would be pretty horrible.

UPDATE 1340 03/07/09: this news just broke. The theft was via standard abuse of privileges (something that is not punishable in eve although the subsequent sale of the kredits is) while the value of the theft was ~£3,000 and technically hard to punish legally it will be more and more common and is only a matter of time before someone starts testing this legally.

Chick Tracts

2009-06-29T02:14:00.000-07:00

The chick tracts are immensely annoying short web comics that promote Christianity, they're not so much annoying for their promotion of religion (what ever floats your boat) more for their utter lack of logic and horribly contrived feel that should fail to persuade any rational reader of their truth (a perfect example is this on homosexuality see if you can reach the bottom with out rage!).

Anyway for those of a lovecraftian bent this is a wonderful parody

Sex, drugs and rock n' roll.

2009-06-18T17:36:00.000-07:00

Well one out of three isn't bad. Here is a summary of some interesting reports on drug use. These interest me for a couple of reasons: I have tried various chemicals and enjoyed them; I have read (well skimmed) various government reports most of which go against the accepted wisdom that 'drugs are bad'; finally I have always wondered why people are so blind to the affects of alcohol/tobacco and so vocal on the affects of everything else.

While this is the age old argument there is VERY little reason why alcohol should be acceptable while cannabis or MDMA isn't. There are two reasons for my confusion; firstly while none of these drugs are safe (don't believe me look up liver failure from alcohol and permanent psychosis for cannabis) secondly I fail to see how most people don't realise this. I would expect it's from the propaganda that says drugs are bad you are hooked the instant one touches your lips (or vein or what ever) and that they will kill you in seconds.

It is this second point that depresses me the most; the double standards I can understand to a degree: people are comfortable with booze but the rest is strange and scary, fine. The second point though raises a much more dangerous truth: that we should lie utterly to children and ourselves. This isn't the science "this is mostly true but not everything" lying this is out right driving fear in to people's hearts to the point where those people who genuinely need help (ie addicts) cannot admit it most of the time because of the stigma and hence are denied what should be an avenue out for them. It also raises the worrying question of what else we let ourselves be feared into (ID cards anyone, net monitoring?)

This is a wonderful highlight of an endemic problem in our society: that expertise is no longer trusted, in any way. I'm not saying we shouldn't question what we are told be experts or anyone, but they are experts for a reason. The number of government policies that are created despite experts turning round and saying "what you planning is rubbish" is a sad indicator of something found at all levels of society.

I hope it ends soon...

New news on old news I missed

2009-06-18T04:38:00.000-07:00

This (yes one day I'll come up with a better start to these but until the bite me) is a worrying story. The reasoning behind a trial without jury is sound, the case had been seen three times previously and fallen through each time due to jury tampering. It still makes trial by judge alone a worrying situation especially in criminal cases.

While our current government (incompetent and rubbish as it is) probably wont start black bagging and trying without jury its the sort of law that means if someone is an arse at a future point there is worrying precedent, especially when combined with some of the other more interesting laws that have been passed in recent years.

More worrying news from the gov, this sort of stuff will most likely bite them in the arse as public backlash. Ironic though that a nominally left leaning centrist party has introduced so many laws and policies that look like they should be in 1984...

More joy from YouTube and the Discovery Institute

2009-06-12T04:13:00.000-07:00

Two related videos today, both by the same person highlighting what will become an interesting problem online: the use of cease and desist notices to take down and censor content. This is nicely tied to another irritant of mine which is creationism (now going by the name of intelligent design). This is the sort of insidious anti-science that could set us back years if it gets accepted. Firstly ID explicitly relies on a none testable hypothesis: that at some point all of life was designed at a deep level. This can only be tested if they can prove that a biological is irreducible, that is that there is no way in which it could have been produced naturally, this in itself is the definition of supernatural.

Moving away from my loathing of ID the second part that is interesting is the use of law to smash websites; especially hosting sites like youtube. These sites have to comply quickly (I expect they use automated services) as failure to do so makes them liable BUT it does mean there is an easy was to remove content that you don't like.

Luckily the internet does not forgive and it does not forget.

Here are the vids, the first is the vid that was taken down the second is a vid about that act.

This is a short video of a carbon nanotube muscle, it is very cool. This sort of technology can be used for all sorts of interesting micro motors, engine parts and other machinery such as very manipulatable arms for robots (search and rescue anyone with a cam mounted on one of those to look inside the rubble).

Next is this interesting article on grown organs, so far a bladder, bone marrow and a rat's heart have been made with the bladder having been successfully transplanted into a patient. This is the future of medicine: constant refreshment of organs as and when they are needed. Neat huh?

Chiropractic and other fun

2009-06-10T17:02:00.000-07:00

Two interesting posts that I'm linking to today. First is a very funny letter being sent out to various chiropractic peoples informing them that they should be very careful about what they claim to be able to help with. Second is an interesting (American) post on the break-down of their government's spending.

Starting with the latter (the government spending) click here the blog itself is a favourite of mine with lots of interesting physics and astrophysics posts but what is genuinely interesting is how the break down of spending appears: only 0.8% is on science and technology combined. all it beats is general government. That's NOTHING, I find it highly annoying when people complain about the costs of for example the LHC; especially as they rarely realise that the $5 billion (I think ~£4bn) is spread over about 25 years of total R&D compared to the Olympic games which will no doubt run to more than its predicted £4bn budget for not even 1 year of heavy use. Anyway an interesting post and one well worth sending to the 'science is a waste of money' brigade.

The former post I won't comment on other than to say that considering that Simon Singh currently has to prove that the claims of the BCA were deliberately misleading this seems to be a wonderful piece of evidence that they may have been...

Job hunting

2009-06-02T11:50:00.000-07:00

Well it's summer again which can mean only one thing: time for another soul sucking summer job. In years previous I've been very lucky in being able to get jobs through friends this year with the economic situation being what it is it doesn't seem as likely, certainly no luck so far. The upshot of this is that today has been spent a) in the sun and b) sitting in my room trawling through pages of job agencies which mainly consist of various recruitment firms pertending to be employers looking for jobs rather than agencies looking for more people to put on their books, oh the joy!

Instead of doing further searching and CV massaging I'm here; procrastination how I love ye!

Disgust

2009-06-02T07:41:00.000-07:00

It takes a lot to sicken me online and this manages it. What I find sad about it is the utter contempt, it takes true work to write something so utterly hate-filled, then to publish it and pretend to be the good-guy is amazing.

I don't have a huge interest in the whole abortion debate - personally I think that abortion should be an option and in late cases where the woman's life is in danger it may be the only sensible option.

The other thing that shocked me a bit about this article is the whole-hearted love for capital punishment this isn't someone who thinks that it is whats needed as a deterrent but that it should be loved and used as such.

and I thought reading fundies say the darnedest things helped expose me to the extremes of human belief - looks like I have to work harder.

LOTR Fail

2009-06-02T07:36:00.000-07:00

This video is annoying me. I like LOTR but the thought of a kids game of it grates at a fundemental level. A large part of the attraction to LOTR for me is that it has so much depth (the huge mythology woven through, the languages and the sub-plots) and I don't think the games will pick up on this even remotely, the films did well in balancing it and created something beautiful. By the look of it though a cell shaded game aimed at children and their parents probably wont.

Ah well

This would be funny if it weren't so true

2009-06-01T08:41:00.000-07:00

This article sums up the onion pretty well. It's funny. It's accurate. And painfully true.

I don't know if it's just my tinfoil hat blocking my ears but when you see stuff like the Simon Singh case the various insanities that are always about (ie creationism and vaccine quackary) it just seems that anti-science is on the rise (ironicly often helped by the 'net).

This is a problem on a number of fronts. Firstly anti-science generally goes hand-in-hand with loss of critical thinking which is not what you want in a democracy - even more so given the current economic and political climate (hello BNP, anyone?) The second reason is that in the increasing technical age that we live in loss of scientific thinking doesn't help anyone. Our current knowledge is close to pushing science far beyond anything we've previously seen: both nanotech and biotech have the potential to fundamentally change how we live beyond even what the internet has done. This will not be helped if half the population are unable to think critically and more importantly unable to get hold of the information that will help with this.

Now more than ever we need GOOD science writers and a GOOD flow of information. Here's hoping it happens

viva la revolution!

2009-05-28T04:54:00.000-07:00

Well ok maybe not revolution but this is a excellent article on the affect that the internet is having upon the world.

More precisly it explores the emerging digital socialism that the internet has helped breed. More and more systems are being developed collaborativly (linux, wikipedia etc) and for free.

I won't go on because right now my brain is hungover and I can't form thoughts properly but to quote my friend

"You're foolin' yourself mate, we're living in an ad-hocracy. Come and see the meritocracy inherent in the system!"

I hope this is a hoax...

This is a wonderful money spinner and a horrible idea.

I'm all for highlighting the general daftness of most religous views but the thought of people paying money into a bank for the express reason of coming back from the dead and claiming the money is just painful.

Age of obession

2009-05-22T07:35:00.000-07:00

This is an idea that I've been bouncing around for a while and still keep coming back to so I'm going to inflict it upon you (who ever you are).

The premise is simple, over the last few hundred years society has changed drastically (in case you've been in hibernation or something). A few hundred years ago we were mainly rural family/village centred, with the industrial revolution we became urban but remained locally focused (either about jobs or just road/church what ever). As last century progressed the focus has changed again from job to friends who may be much more spread out than previous networks. With the advent of the internet this has become global and based much more upon common interests, for example I could go to most major cities of the world and have crash space through friends I've made juggling.

This is the age of obsession, a lot of people now meet via the internet, its no longer taboo to meet someone from online or even date/marry someone met via IRC or WoW. Now more than ever we can group with people not because we have to but because we want to through common interests.

These groups form a double edged sword on the one hand its utterly possible to realise your not freak for liking Bavarian folk music as played by chinchillas on the other hand the same is true for being a fascist or snuff-film enthusiast. Hopefully the internet will still help people account for this and experience the lovely corrective glow of peer pressure.

While often labeled a bad thing peer pressure is vital, it acts as a normaliser, I'm all for weird but when it is considered normal your get into trouble. This is where peer pressure comes in, those dirty little habits you have don't get worse because of peer pressure - unfortunately it is also through peer pressure that shame for normal things can occur - for example enjoying that most dirty of acts - sex. It still amazes me that people are more worried about sex than seemingly any other act that humans perform on one another.

Anyway I would be very interested to ear whether people think that this new 'Age of the obsessive' will be good bad or indifferent. Personally I think it will be for the better as it will allow people passion that has until recently been frowned upon, I'm sick of hearing "you have too much time on your hands - how else do you do all this fun stuff?" most of the time the answer is simple - I'd rather be messing about learning to program than watching 99% of whats on TV.

Roll on the age of the geek where passion for the strange is respected!

4chan iz in ur mainstream, corruptin ur yoof!

2009-05-22T03:21:00.000-07:00

This made me smile this morning. 4chan (for those of you sane enough to avoid it) is the internet cess-pit. All those mind searing images? those terrifying memes? They come from 4chan (and a few similar sites).

I've been wondering how long before it was mentioned by name in the main stream news for a while. Whats interesting is that obliquely 4chan and its ilk are mentioned often - normally confused with the 'terrorist group' anonymous. This is explicitly wrong. Anonymous is not a group - it is the outward affect of the anarchy of 4chan and co. These are the places that have no rules and upon which anything goes.

The reason anonymous isn't a terrorist group is that it is not organised, Project Chanology was a meme. Lots of people thought it would be fun or interesting or agreed - so it happened.

This is the new face of protest: flash memes that spread across the internet in a matter of days and then die or explode. Two other good examples are the circle line pub crawl last year (spread via facebook) and the G20 protests this year (spread via facebook and twitter). These are the early sightings of the net truly showing its power - not just breaking news faster and better but impacting upon the world.

The original version of these phenomena were flash mobs - these were light hearted displays of surreality. They have changed and become a method of demonstration as well as a method of anarchy. Which is the only way to describe a lot of the internet.

Stories like the one on the bbc today are just a way of showing how powerful peoples urges and mob mentality can be and online a mob can be huge (4chan's /b section has several million hits a day and managed to get its founder posted as the Time magazine's number one person in the top 100 as a prank as well as a proper interview).

It's things like this that make it easy to see why so many people want to control the internet. It also makes it pretty clear why they will fail. The music industry tried to stop napster and got winMX and so on - these got shut down and we got bittorrents if these die more dark nets will occur (invite only networks for p2p file sharing). The same is happening more generally with content. A lot of the reactions to this story on the bbc page were "why doesn't every youtube video get checked" and "how can this be allowed to happen". This kind of thinking doesn't work online. The responsibility is for the person to stop things to moderate themselves.

Big brother may be watching you online but can't really stop anything - only the people online can change the internet. This doesn't mean that 4chan will be stopped - but it does mean that people need to take things into their own hands and moderate, mark down and report.

oh and supervise their kids online if they don't want them to see porn.

Charles Stross is a dude - near future sci-fi is a) VERY interesting and b) not often done well. He pulls it off - if your interested I highly recommend accelerando.

Either way this is his keynote speech from a recent MMO conference - which doesn't have too much to do with MMO's but a lot to do with the future of the internet and computing in general.

The concept that I think is most interesting and already semi-visible within current high-end gadgets (ie the iphone) is the dissolution of the net-space/meat-space boundary (ie internet becoming part of the real world rather than something on the other-side of a screen). This is something that will be most likely the next paradigm shift (the advent of the 'net was the last one). Moving to a society that treats information and the access of it as a basic human right. Currently its only the hard-core netizens (ie me) that get annoyed when they are cut off from internet access but this is rapidly changing.

The business and academic worlds have accepted email as the standard method of communication, Twitter and its blogging brethren are becoming the accepted methods of breaking news (see swine flu and the Mumbai bombings). While much of the populous consider the internet a hobby or something to use to send the odd email it is rapidly (for people under 30) becoming the only method of communication and research.

In my case more and more of my 'luxury' purchases (ie DVDs) come from online and using google maps on my phone has saved me several times (can't wait to get my iPhone once i can afford it). With things like the sixth-sense in development and pushing more of the internet into the real world.

Going back to the speech I think one of the most interesting aspects of this is that it is predicted within the next 20 years - with e-readers and similar already hitting the market as well as the iPhone considered the bench mark for next-gen mobiles I wonder if a lot of this won't be here sooner. It's also interesting to see how the rate at which we lose the ability to predict the future is lessening. In the 1900's people thought they could see clearly to about now. Now people are un-willing to bet beyond the next 5-years let alone several decades.

Weighing in (feather weight stylee) on Simon Singh..

2009-05-21T05:47:00.000-07:00

For those of you haven't heard of this story click here otherwise keep reading (a copy of Simon's piece can be found here).

This is going to be pretty quick as I expect what I'm about to say has been said before by people much better at it that myself but here is my take.

Firstly Simon did say something a bit dumb.

You might think that modern chiropractors restrict themselves to treating back problems, but in fact they still possess some quite wacky ideas. The fundamentalists argue that they can cure anything. And even the more moderate chiropractors have ideas above their station. The British Chiropractic Association claims that their members can help treat children with colic, sleeping and feeding problems, frequent ear infections, asthma and prolonged crying, even though there is not a jot of evidence. This organisation is the respectable face of the chiropractic profession and yet it happily promotes bogus treatments.

That is not a statement to win friends. Equally though it doesn't deserve to be labeled libel. The piece is clearly comment/opinion to begin with and within the realms of comment/opinion the claim that there "is not a jot of evidence" should be reasonably permissible - the argument should be clearly that within the author's opinion there is no reputable evidence that supports the BCA's claims.

This isn't how the court has seen it.

In fact the court didn't even hear the case as the judge read a pre-written judgment as soon as the parties had said their piece.

This judgment was impressive in taking the case far beyond what was expected (even I expect by the BCA) in that by using the word "bogus" Simon supposedly meant that BCA made its claims with fore-knowledge that they were harmful (some of them are but I don't think many chiropractors believe this). That the BCA practices maliciously is clearly far more than Simon meant through the use of the word "bogus" (in fact I've never known it to have the connotation that something was maliciously false just false).

This case is terrible on two fronts - firstly it highlights some of the problems with libel rules, secondly it shows just how important good scientific reporting is and how hard it is to produce.

In terms of libel like a lot of the grayer areas of law its a very difficult thing to balance - too much on the side of the plaintiff and it becomes to write anything without either filling it with 'apparently's and 'maybe's or being sued. Too far the other way and you can say what you want with impunity.

Whats interesting about this in terms of the law though is it highlights the problem of online blogging. If Simon had initially published his piece as a blog would the reaction have been the same? whats going to happen when blogs start getting picked up and published by papers? Will it be libel in the country posted from? from the country its hosted? In the US blogs are protected speech and cannot be sued for libel. As more of our journalism is done from the net these sorts of problems will arise.

Moving on from the legal aspects (which I can only question as my law knowledge is pretty poor) the journalism aspect is even more interesting. This sort of case is a huge problem for scientific reporting. The bottom line is that this case represents a large group suing someone for being critical of their methods.

Scientifically Simon is reasonably well supported - there isn't much good evidence that chiropractic treats much other than bad backs. Saying that shouldn't get you sued. Even in a national paper - if there is a genuine scientific basis for a statement saying so shouldn't land you in trouble.

If we're being fair so long as you set it as opinion you should be allowed to say pretty much what you want. It doesn't work but it might encourage people to be a little more critical in their assessment of claims made by people. Libel laws are their to protect people from unfounded claims - unfortunately a lot of organisations know how to avoid them and a lot of individuals don't.

Just a warning - be careful of acrobat reader

2009-04-29T12:43:00.000-07:00

Interesting story here about Adobe reader (the thing that opens those wonderful pdf files you get all across the net). Basically there is a critical bug in the software.

Critical bugs in terms of net stuff tends to mean that someone can hack into your computer and do lots of fun stuff. Proof-of-concept code already exists for this vulnerability so its likely that malicious code is already out there. This seems similar to another vulnerability found a while ago.

There are two simple things that you can do to make sure your protected from this. First option is to disable javascripts in adobe (under options i believe. The second option is to download a free adobe alternative.

either way be careful with which ever pdf reader and which pdfs you use.

"its natural" do you say this? punch yourself.

2009-04-29T04:05:00.000-07:00

This is a wonderful blog post by one of my favourite bloggers, blag hag.

A simple discussion of what is actually natural when it comes to animal mating habits, and yes there isn't really anything that is natural or 'normal'. This is one of those arguments that really does annoy me on two fronts: first as the post shows there isn't any single mating habit that is natural. Second the naturalness of an action is a rubbish rationale to use with relation to humans, again as the post reports many animals eat their young, or their partners or carrion.

The naturalness of something is a stupid arguement and the sooner we move on from it the better. Either everything is natural (we are after all products of a natural environment) or we are better than that and it doesn't matter anyway. We certainly can't claim that some subset of our actions should be natural (sex etc) and another it doesn't matter (wearing skins of other animals).

WBRTBN films...

2009-04-28T08:50:00.000-07:00

....or "White Background, Red Title and Blue Name" films.

In terms of poster design these films suck. They are universally the same sort of film: 'quirky' (ie mass produced) rom-coms, these are the films where a board of people have sat around and brain stormed what ever hasn't been done recently and make what ever falls out:

"rom-com"
"ohh lets have a ghost"
"done! where's the coke?".

I hate this kind of film (I've yet to see one I've enjoyed) and it really annoys me that they seem to be breeding - I guess in a recession they're cheap and easy to produce.

Either way utterly sick of seeing the adverts for them on the sides of buses - they could at least try to vary them and try to stand out/lighten my day a bit.....

This annoys me

Gah... stupid paranoid ....

More government optimism

2009-04-27T04:31:00.000-07:00

Well looks like the government is shelving the database of all our communications idea (at last!) in preference of asking Communication Service Providers (CSPs) to log who connects to what and how - ie if you access Facebook from your iphone or similar. This seems to be an extension of the existing laws regarding telephone logs that allow the police and security services to see who called who when.

What strikes me about this is that it is a £2b scheme that will most likely be futile. Just as cheap pay-as-you-go mobiles have made telephone logging pretty obsolete because it becomes very difficult to log who calls who when the phone isn't registered it is very difficult to glean useful information from the internet when you can send stuff via a proxy and have the information of who your talking to disappear especially when systems like The Onion Router (TOR) exist that helpfully cover who your talking to and where without any real effort.

Basically this seems a lot of money on a system that will achieve next to nothing. If people want to organise via the net there are a hundred ways of doing it that make it near impossible to trace who spoke to who, asking the CSPs to log this information doesn't really help at all especially when you don't even have to route most of your stuff via your ISP - open DNS servers in other countries will allow alot of the useful (to the services) information to by-pass the UK utterly.

The anarchistic social experiment that is the internet

2009-04-27T01:45:00.000-07:00

There's an interesting story here of a family in America who were very upset to find that photos of their daughter's death were available online. The girl had died in a car crash and some cops had taken photos as a cautionary tale which then escaped online.

I think there are a lot of interesting aspects to this story: firstly the wonderful way that pretty much all censorship attempts online eventually fail (google search for the images they're trying to ban they're still readily available), secondly how pretty much all legal systems fail online and finally how depressing how anarchistic (and deprived) the internet can be.

The first point I think is most simply shown here, a very daft woman on LBC radio said some very poorly thought out things about how taking MMR jab was optional because no one ever got those diseases any more. Ben Goldacre responded by posting the radio debate online as an example of truly poor science and got asked to removed it. Soon after the radio clip was available and talked about on more than 150 other blogs either in bits or as a whole. The internet doesn't like censorship - stop trying it on.

The legal aspect is interesting. Privacy is a right, but online you only have as much privacy as you protect yourself and that's not easy. This is especially true when something like /b/ decides to come after you (I won't link there its easy enough to find). Well I say 'decides'....

This comes down to something that pretty much all governments, people and organisations don't seem to have realised: the internet is anarchy. There is no law in any way, not yet and so sites like /b/ proliferate, not because people are suddenly worse online - just that they can relax and these sites become the ultimate games of dare - you can do what ever you can think of and type. Just every now and then someone is stupid and actually does it. The internet has brought out some truly nasty sides of people; but I hope this will fade.

The internet is still socially very young - people are still adapting to it in a social way and the anarchy is to be expected - sooner or later some form of law will emerge as will more of a social ethos, and no just because Facebook is a social site doesn't mean the internet has a social code or ethic - this will take a while to evolve.

Anyway moral of the story: nothing is private online so think before you upload other people's personal information (I think that the cops involved should face charges).

It's truly terrible what some people have done to the family. Emailing them with pictures from the crash scene is vile but I think their time would be better spent ignoring it.

Hopefully stories like this will be few and far between and hopefully people will learn from them.
