Power 2010’s Power Pledge

Power 2010 have decided on the five key issues for their Power Pledge.

– Introduce a proportional voting system.
– Scrap ID cards and roll back the database state.
– Replace the house of Lords with an elected chamber.
– Allow only English MPs to vote on English laws.
– Draw up a written constitution.

I am a strong supporter of the reforms to introduce proportional representation and to scrap ID cards and roll back the database state.

I believe that the current first past the post system causes many people to feel disenfranchised because they live in a constituency which has strong leanings one way or another and their vote has no effect. This system all leads to negative voting where people vote for candidates for parties they don’t particularly support but which represents the best hope of defeating the party they’d least like to win.

The ID card and National Identity Register should be opposed because of the principle that citizens in a free democracy should be allowed to go about their lives without government intrusion. The project is also so technically flawed that it will inevitably either have to be scrapped because it is unworkable in practice or because it causes one of the very problems than it is designed to combat namely an increase in identity theft.

The House of Lords should be replaced with an elected second chamber but the form of the second chamber needs to debated intelligently before it is implemented. Replacing the Lords is a major undertaking and there will not be an easy transition from the present house to a new wholly elected chamber.

Review: Exit Through the Gift Shop

Exit Through the Gift Shop

Exit Through the Gift Shop is a fascinating documentary about filmmaker Thierry Guetta who in his failed attempt to make a documentary of Banksy became himself a street/pop artist and subject of this documentary film made by Banksy.

Thierry Guetta is a fascinating character who through his cousin became an unofficial documentarist of the street art world. It was all based on a lie though as he was never really making a documentary as all the footage just got stored away never to see the light of day until Banksy got his hands on it.

Having failed to make a coherent film out of his footage Guetta hands the task over to Banksy who casually suggests to him that he should try his hand at being an artist. Banksy later comes to regret having done so when he realises to what extreme Guetta has taken the comment as Guetta launches his career as Mr. Brainwash.

However I think that all is not as it seems and that the film has been produced by Banksy in order to quell the criticism that he has sold out. Once we get into the part of the film that chronicles Guetta’s insane art exhibition as Mr. Brainwash it becomes an attack on the art scene and the bogus nature of the people that buy into it.

There is literally no originality to any of Mr Brainwash’s work it is a mess of extremely derivative work that lacks a connecting theme other than it is derived from the work of artists that Guetta admires such as Warhol, Banksy and Shepard Fairey. He is however extremely successful as the show attracts huge crowds and he sells hundreds of thousands of dollars ‘worth’ of work.

Critics praise his work as being commentary on the work of other artists, but I believe that it isn’t and that the fact that it is entirely lacking in substance is deliberate. I think that both his name and his work are a joke/scam being pulled on the art world and are a fabrication created by Banksy. That they will buy any old shit if there is the smallest connection to the name of Banksy

However now the illusion has become reality in a world where anything can be called a work of art if it is produced by and called such by a person that a number of people believe to be an artist.

Review: The Girl who Played with Fire

The Girl who Played with Fire

The second book in the Millennium trilogy by the late Stieg Larsson is as good as There Girl with the dragon Tattoo. Dark secrets from Lisbeth Salander’s past cause her to be implicated in the murder of a young couple. Journalist Mikael Blomkvist is also connected to the case and in trying to prove Salander’s innocence uncovers things that powerful people do not wish brought to light.

Larsson has created in Lisbeth Salander a truly remarkable character and in this book has crafted yet another intelligent and gripping thriller around her.

What is your mother’s maiden name and other insecure security questions

Security Researchers at the University of Cambridge’s Computer Laboratory have produced a whitepaper titled Evaluating statistical attacks on personal knowledge questions.

Aside from the fact that the answers to these questions are readily findable for celebrities and increasingly easy to uncover through social networking sites for the average individual the researchers found that even guessing is good enough to render the system insecure if carried out on a wide scale.

There is a strong result that anything named by humans is dangerous to use as a secret. Sociologists have known this for years. Most human names follow a power-law distribution fairly close to Zipfian, which we confirmed in our study. This means every name distribution has a few disproportionately common names—”Gonzalez” amongst Chilean surnames, “Guðrún” amongst Icelandic forenames, “Buddy” amongst pets—for attackers to latch on to. Combined with previous results on other attack methods, there should be no doubt that personal knowledge questions are no longer viable for email, which has come to play too critical a role in web security.

I think that until such time as the companies that use password reminder questions as a security method change the system they use I recommend that people give a nonsense answer to the question. If you are sure that you’d never need to use the password reminder facility then you could just use a completely unguessable random alphanumeric string as the answer. Otherwise it would be a good idea to choose something memorable as your nonsense answer that you consistently use e.g. Throatwobbler Mangrove unless inexplicably that does happen to be your mother’s maiden name.

There has been other research in the last few years into this subject.

Time travel on Lost – the science bit

A post on Metafilter reveals that Caltech physicist Sean Carroll recently tweeted that he was meeting up with Lost producers Damon Lindelof and Carlton Cuse. This was posted to the forums at Lostpedia, prompting immediate spoiler complaints … so Carroll signs up and drops in to the thread to clear up the confusion, also offering some of his thoughts on the use of time travel in the show and referencing a longer blog post he wrote shortly before the start of the final season.

Qvantamon in a reply to the thread on Metafilter gives a rather homicidal theory of time-travel which addresses the notion of paradoxes.

Painquale, depends on how much you want to split hairs. You cannot alter your past (in the broadest sense – all the history of the universe as it played to cause your current state). Or, alternately, you cannot alter your past (same broad sense).

For example, let’s say 50-years-in-the future Painquale is just about to enter a machine that will, in fact, just disintegrate him at the sub-atomic level into pure entropy (his existence is not really a necessary condition). There’s a non-null chance (never mind the amount of decimal places) of, right now, 2010, zillions of sub-atomic particles just tunneling all at the same time into the exact same configuration as 50-years-in-the-future Painquale (supposing memory/thought process/sentience is a physical phenomenon). With a strong many-worlds interpretation, since that’s possible (no matter how infinitesimally improbable), that’s necessarily one component of the universe’s wave function (that is, one “parallel universe”), so, there’s definitely one branch where it just happened. If you ask that particular “time-traveling” Painquale, he’ll tell you that he sure is a time traveller, he disappeared from the future and appeared here. Never mind that there’s no causal relation between new-Painquale showing up and old Painquale disappearing, in his mind it’s solid. He can of course, go ahead and kill present day Painquale, and it won’t do shit, as there is no actual causal relation (as I said, that future where he thinks he came from may even have absolute zero chance of existing). Of course, he can decide to disintegrate himself again, and THIS pretericide-Painquale configuration can again also just show up randomly 50 years later, in another infinitesimally improbable branch of this same branch of the universe (again, no causality violation here). Again, no time travel, just particles tunneling around. But 2060 pretericide-Painquale of course has the whole causal relation in his mind. And no one around him will have any idea who he is (aside from being the guy who said he came from the future and killed Painquale), which is exactly his expected outcome of a time travel. Success, for all he cares, and no actual causality laws broken.

This is pretty much how I believe time travel would work if it were more than merely theoretically possible.

I was never happy with the solution for the grandfather paradox that some physicist put forth (I want to say Stephen Hawking because I’m surely I’m vaguely recalling a passage from A Brief History of Time) that somehow the Universe would conspire to prevent you from killing your own grandfather so as to maintain causality.

The discovery of the theory of parallel worlds suggested to me a better solution that you could indeed kill your grandfather (if that was your bag) because the man you’d be taking the life of would be from an alternate reality to the one you’d left.

I think that the notion of ‘whatever happened, happened’ can be preserved at the same time as that of being able to change one’s past like Back to the Future’s Marty McFly.

Our schools are failing our children

In the US and the UK it is becoming the norm that children emerge from school ill taught and ill prepared for the world at large.

In the New York Times article Building a Better Teacher an argument is made that there needs to be a new understanding of teaching and be able to distinguish between techniques that really work and those that don’t.

But I think there also needs to be discussions about what we need as nations from our schools.

Seth Godin believes school is a scam it is about brainwashing.

It may be that it is not the quality of the teaching at all but the diet of the pupils. Jamie Oliver in his campaign to improve school dinners found that with a healthy nutritious meal at lunchtime that there were improvements in the children’s mood, behaviour, and even their ability to concentrate.

The hype of cyberwarfare used to control the internet

Ryan Singel writing for Threat Level believes that the Cyberwar Hype Intended to Destroy the Open Internet

With the rise of the internet nation states have begun to lose control of their citizens and have introduced ever more draconian laws to try and claw some of that control back.

The War on Terror was framed as a Cold War for the 21st Century and a fog of fear was spread over the population but that fog gradually lifted as people realised that they were not at risk from Al Qaeda. Even when a nutcase tried to ignite explosives in his underpants on an aircraft and politicians and the news media spewed rhetoric about this dangerous new tactic of the terrorists and how something had to be done most people soon went back to their lives as if nothing happened.

The powers that be needed a new threat with which to control the people and the Chinese hacking of Google and others provided them the framing to do it.

Western civilisation is now under the peril of being destroyed by China in the form of computer hackers.

Google’s allegation that Chinese hackers infiltrated its Gmail servers and targeted Chinese dissidents proves the United States is “losing” the cyberwar, according to McConnell.

But that’s not warfare. That’s espionage.

We do not need as Mike McConnell to ‘reengineer the Internet to make attribution, geolocation, intelligence analysis and impact assessment — who did it, from where, why and what was the result — more manageable.’

The ‘Google hacking situation’ was first and foremost the infiltration of the servers of private industry not an attack on the United States itself. The IT security of American companies is an issue where the US government can be of assistance by offering advice or notifying of specific threats that they’ve become aware of, but not through monitoring and controlling the internet.

Seth Godin on the nature of genius

Genius is misunderstood as a bolt of lighting

Genius is the act of solving a problem in a way no one has solved it before. It has nothing to do with winning a Nobel prize in physics or certain levels of schooling. It’s about using human insight and initiative to find original solutions that matter.

Genius is actually the eventual public recognition of dozens (or hundreds) of failed attempts at solving a problem. Sometimes we fail in public, often we fail in private, but people who are doing creative work are constantly failing.

When the lizard brain kicks in and the resistance slows you down, the only correct response is to push back again and again and again with one failure after another. Sooner or later, the lizard will get bored and give up.

Genius is the creation of 5126 prototypes before producing a viable bagless vacuum cleaner. Or to quote Thomas Edison “I have not failed, I’ve just found 10,000 ways that won’t work.”

How did Hurley get out of his car?

With all the mysteries that are confounding people in Lost it seems that for many people that THE most important question of Season 6 is:

How did Hurley get out of his car after parking so close to Locke’s van?!

To my mind that’s an easy one, he got out on the passenger side.

In this parallel timeline his best friend Johnny instead of deserting Hurley when he found out about the lottery win and running off with Starla, the girl Hurley was in love with, instead remains his best friend and becomes his driver.

Hurley is such a nice bloke that he gave his arsehole former boss Randy a job – of course he’s going to have given Johnny a job too. And what better job than getting to hang out with your best friend and drive him around all day. Johnny is Turtle to Hurley’s Vincent Chase. And Johnny is a pretty skinny guy so would easily be able to get out of the driver side after having parked so close to Locke’s car.

When Hurley meets Locke in the car park Johnny had probably just gone off to get some fried chicken or something so the scene looks a little incongruous.
