mmm hyper fast trading...

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

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

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

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.

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

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.

Food for thought

In the current world climate is Islamophibia the new anti-Semitism?

This is an article that everyone should read. It's safe for work and very interesting, if a little uncomfortable.

Back to revision for me I have a wad of posts waiting to be written up once I finish on Friday

Seismic Shock

go read this article on the police being brought in to warn people off blogging

http://blog.z-word.com/2010/01/we-are-all-seismic-shock/

Will talk about this properly later

Enjoy!

Update!

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

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

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...

Link dump

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

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....

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.

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

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

mmmmm retinal projection...

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.

DNA databases, Charlie and Ben

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.

Chiropractic and other fun

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...

This, sign it, NOW

This is a petition on the Simon singh case - sign it.

Disgust

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.

4chan iz in ur mainstream, corruptin ur yoof!

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.

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

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.

This annoys me

This story really annoys me. It is worrying that a paper is willing to publish something that is quite so wrong.

Gah... stupid paranoid ....
