Comment The Exchange knows who they are..... (Score 3, Informative) 617

Of course the exchange knows who they are - you can't just stuff orders into the market anonymously from your PC at home. I'm mean the exchange needs to know who you are so they know who to charge for the trades. The exchanges aren't happy about people placing and cancelling tonnes of orders - after all they only make money when something trades. You can guarantee that they got on the phone to whom ever was doing this and asked them to stop.

It probably means: We sell each TV for more than the marginal cost of making each TV, but we don't recoup enough money from this to cover the R&D/once-off costs. In this circumstance, Sony is doing what anyone else would do and it makes perfect sense, you've lost the up-front costs, but you might as well keep selling TVs if they are selling more than the marginal cost.

I agree - they also didn't smash the record either, as there wasn't one there to break.

The streamliner, named “Electric Blue,” competes in the “E1” class, which includes cars weighing less than 1,100 pounds. Because electric cars rely on heavy batteries, engineering a speedy vehicle at such a light weight is very difficult. That’s why there were no prior certified speed runs for this class

Hats off to them though, still a pretty impressive feat!

I leave Chrome going for as long I can leave Windows going without grounding to a halt (typically about a month).

You get a nice little update icon on the 'spanner' symbol telling you that updates are available and will be applied the next time that you restart Chrome - otherwise it leaves you alone.

Comment Cable theft (Score 1) 96

This is only going to make the problem of cable theft even worse! My train is frequently delayed because some selfish numbnut has stolen the signalling/power cables to sell the copper. Imagine what is going to happen when they find out that these cables are made out of sapphires!

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.

Comment Re:However, something important to keep in mind (Score 1) 129

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) ...
