Most macros fall under one of three categories. Improving performance by removing function calls or doing work at compile time eg https://github.com/ztellman/vertigo emulates c-style structs and uses macros to calculat

Yes, www.gov.uk is the product of the new Digital Government Service which I linked above. They haven't been around for very long yet and they are currently only responsible for the government web-services but I hope that their success

So, basically you want this - http://digital.cabinetoffice.gov.uk/about/ It's worked so far. It remains to be seen how it will age - maybe in ten years time it will be just as buried in bureaucracy as the rest of

It's interesting that the UK seems to be getting around this by doing stuff in-house. So now we have the open government license ( http://www.nationalarchives.gov.uk/doc/open-government-licen... ) and government web

From what I can see, all of the sibling links just eval javascript. I believe LT goes one step further and uses the jit to replace code, so that even closures (eg event handlers attached to the dom) are updated to use the new code.

What about when the pure code is too slow to run? Or when the pure code is wrong but the jet is right - so that the nook spec is now not sufficient to determine semantics. Let me bury that criticism though by saying that this is the most be

I'm doing this at the moment. We have a gnarly ball of legacy code that is burning out devs. It actively resists any attempt to disentangle its parts and after years of attempts at refactoring it's gnarliness is barely reduced. I&

That doesn't take into account how good a language is for prototyping and experimenting. Even if I have to write in $blublang, I'll probably still prototype it in $petlang for the increased productivity and then port it once I hav

This idea - having locally unrestricted components connected by a restricted, declarative system - seems to keep popping up and never quite taking off. Hopefully sooner or later someone will spin it just right. Some related projects: Opis -

It does make a difference but I messed up the code :S If you try the updated gist you will find that the second distribution appears to converge for a while but always jumps away again. I've run it now for 20540000 rounds and its furth

Sorry, I should have been more specific :S You have assumed a fixed amount in each envelope. The article leaves the amount unspecified but implicitly assumes that there is no maximum amount that could be in the envelope. The problem only be

Goddamn, what does it take to get a cookie around here? :D

by jamii 13y ago
Well, with the distribution I gave it could be $2 (with probability 1/2), or $4 (with probability 1/4), or $8 (with probability 1/8) etc. That distribution doesn't have a maximum. For a simpler example, imagine tossing a

The expected value in the St Petersburg game is actually well-defined - it converges to positive infinity. That is a subtly different result than not converging at all. Both problems are useful.

I think the point he is getting at is that expected value (or even expected utility) is not actually a good measure of human preferences. Additionally, in this problem there are certain distributions over the amounts in the envelope for whi

by jamii 13y ago
Not so much that it leads to nonsense as that naively applying expectations doesn't always work. This is a contrived example, but it's not uncommon in eg random walk theory to hit upon cases like this where the expectation does no

by jamii 13y ago
I'm not assuming that that is the distribution. I'm saying that the problem as presented is underspecified, but even if you give this specific distribution in the problem you can still cause confusion. Assuming stuff is bad but

The problem here is that you are adding together two values for a specific case of x and then adding together the result for all values of x (is that clear? probably not). It's analogous to another age old problem: what is the value of

by jamii 13y ago
Go ahead and run a few million simulations of the problem and graph the running mean over time. You might be surprised :) Be sure to use exact arithmetic (eg http://docs.python.org/2/library/fractions.html )
