Comment Problem with face recognition (Score 3, Informative) 375

I was looking at facial recognition algorithms some while back, the problem is you get too many false positives.

The problem with all of these algorithms is that it doesn't matter how accurate they are, they are only ever going to be a way to reduce the search space - you should never base a decision solely on the algorithm telling you "this is person X".

For example, some sales person says "Hey I've got this great facial recognition software it is 99.99% accurate!" (that's better than most facial algorithms out there) sounds pretty good right! - Wrong!. Suppose you set it up to look for one terrorist at Heathrow airport. The system is likely to flag up 650 000 people a year (based on 65 million passengers a year); of course it gets even worse if you start looking for more people.

This is one of my pet hates too - it should really be GPM (Gallons per Mile); probably some conspiracy with the motor manufacturers. On another slightly related note: My car gives me an average MPG for each trip. If I do a regular trip (say to work), and I want to figure out the 'cheapest' route, I want to know the 'total fuel used' per trip. If I go for the route with the lowest average MPG figure, it might be a longer route with less stopping and starting, which actually uses more fuel overall. Of course, it gives me the distance too so I can work it out, but why not give me the 'total fuel used' information too?

The point I was making is that people are driving are driving slowly because it is confusing. People could be driving slowly for a number of other reasons: i) They have to stop to give way. ii) There are speed restrictions. iii) ...

Sharks Seen Swimming Down Australian Streets Screenshot-sm 210

As if the flood waters weren't bad enough for the people of Queensland, it now appears that there are sharks swimming in the streets. Two bull sharks were spotted swimming past a McDonald’s in the city of Goodna, Butcher Steve Bateman saw another making its way past his shop on Williams street. Ipswich councillor for the Goodna region Paul Tully said: "It would have swam several kilometres in from the river, across Evan Marginson Park and the motorway. It’s definitely a first for Goodna, to have a shark in the main street."

Examining Indie Game Pricing 188

As the second Humble Indie Bundle flourishes, having taken in over $1.5 million in pay-what-you-want sales, the Opposable Thumbs blog has taken a look at indie game pricing in general, trying to determine how low price points and frequent sales affect their popularity in an ocean of $60 blockbusters. Quoting: "... in the short term these sales are a good thing. They bring in more sales, more revenue, and expand the reach of games that frequently have very little marketing support behind them, if any. For those games, getting on the front page of Steam is a huge boost, putting it in front of a huge audience of gamers. But what are the long-term effects? If most players are buying these games at a severely reduced price, how does that influence the perception of indie games at large? It's not an easy question to answer, especially considering how relatively new these sales are, making it difficult to judge their long-term effects. But it's clear they're somewhat of a double-edged sword. Exposure is good, but price erosion isn't. 'When it comes to perception, a deep discount gets people playing the game that [they] wouldn't play otherwise, and I think that has both positive and negative effects,' [2D Boy co-founder Ron Carmel] told Ars. 'The negative is that if I'm willing to pay $5 but not $20, I probably don't want to play that game very much, so maybe I'm not as excited about it after I play it and maybe I drive down the average appreciation of the game.'"

The only problems is lack of choice of hardware and paying a premium for another OS:

From Dell (in the UK) if you want Linux, you are limited to exactly 1 laptop; and if you spec it the same as the equivalent Windows offering it works out exactly the same price (£249).

Which kind of begs the question:
Are Dell making more money on the Linux version? Or do they have to pay Microsoft for this laptop anyway?

According to truecrypt (and my limited understanding). What you do is this:

1) Setup an encrypted volume (password=dummy)
2) Put some plausible files in the volume (secrets.txt - full of information you don't mind others seeing)
3) Create a hidden volume (within the first encrypted volume) (password=secret)
4) Put your real secret stuff in here.

When you use the partition you use the (password=secret) and get access to the hidden volume, should the police turn up tell them that the password is dummy, and all they see is "secrets.txt"

The clever part is that it is impossible to tell whether there is a hidden volume or not as the space that it occupies is normally full of random data anyway.

I unfortunately read the article...

He then created a cloned card, and with help from another technology expert, changed all the data on the new card. This included the physical details of the bearer, name, fingerprints and other information.

Lets hope this puts the final nail in the coffin for this stupid idea.
