Interesting. So maybe it is an evolutionarily stable strategy, if you assume it's too hard for the fish to keep track globally of where they are in the shoal (and are therefore limited to strategies where they only…
Why would they do this though? Why wouldn't a gene for 'cheating' (e.g. not slowing down when you reach the front) to avoid danger be favoured by natural selection? Animals with complex social structures (like us) avoid…
You're probably right - although saying the accusations are "nonsense, utterly ridiculous and should be ignored" isn't strictly speaking the same as saying that they're untrue. GCHQ could believe that (although they…

So if hypothetically Gox was the only buyer for bitcoins trapped in Gox, would they be buying them with real USD, or with 'trapped in Gox' USD that may or may not turn out to have any value?
Question from someone who doesn't know much about this: is it possible to know that there is a genuine market in these MtGox bitcoins i.e. that $350 is a genuine market price and not just something made up by the…
Currently (I'm in London UK) Minecraft has a huge folllowing among boys aged (roughly) 8-14. As long as that demographic remains obsessed there'll be a constant new market.
I think "how many golf balls can you get in a double decker bus" is a fair question for assessing whether someone can apply basic maths to a to a real life (i.e. not perfectly defined) problem. If that's a skill the job…
Presumably an Apple-run bank would protect me from scams by only allowing me to spend my money on Apple-approved products and services?
a velocity 20 parts per million above the speed of light
This makes me worried about hash collisions as well. The article implies that a file whose hash matches something they already have will never even reach their servers - so presumably I just have to keep my fingers…
This makes no sense to me. If it's really possible to "resell these domains for considerable profit" then why aren't you doing it yourself? Or, if it's not, then surely you're just preying on the greed and gullibility…
I don't see why you had to be so rude to them, just because customs in their circle are different to your own. A simple "You go ahead, I'm just going to pay for my own" would have sufficed.
I fear some naive young US-based Anonymous participants may soon be getting a very rude awakening (if the FBI and Secret Service respond to this by making an example of them). Edit: downvote me all you like, but you…
I've often wondered how long it will be before TV companies edit the video of sporting events to replace the adverts in the stadium with different ones they've sold themselves. Given the adverts are in fixed places it…
I greatly enjoyed his eccentric and opinionated book 'Calculated Bets' on writing an automated system for betting on jai alai (although the story petered out rather lamely when the grad students he relied on to write…
Do you know what a meme is? How could a cliched rhetorical device not be one?
It's certainly possible to imagine universes in which that would work. But in ours, where stuff is made of atoms, I can't see you positioning the mark on the rod any more precisely than the width of an atom, which I…
But I would imagine a lot of those market makers are betting their own money. This is a fund i.e. they're betting other people's money. I won't be investing!
Perhaps I'm stupid - certainly I'm no economist - but I don't see what's wrong with naked short selling. For a market to work well you want liquidity, in order for the traded prices to reflect all the information known…

I'm afraid my username doesn't reflect any deep knowledge of the field. I studied probability at an undergraduate level many years ago, and still use it in my hobby (writing 'bots' that run automated trading strategies…
I was quite excited when I saw that New Scientist - generally a pretty good magazine - had a piece on the maths of gambling. But unfortunately it turned out to be an extremely poor article. The first three sections - on…
If you own the copyright to the whole project (because all the other contributors assigned copyright in their contributions to you) you can presumably distribute it under any licence you want. But you can't prevent…
The trouble with fewer better wagers is that wagers - even very good value ones - can lose. So if you're only making a few of them there's a significant probability of losing overall. Your expected value may be high,…
