The end of the article seems to say that Megaupload is US-based. As I understood it, many of the provisions in SOPA were designed for use against non-US sites. I suppose that if Megaupload had operated purely on foreign soil the US may not

I haven't read the tutorial at all, but in dependently typed languages the type (Fin N) is exactly the type of "natural numbers under N", and I expect that is what Edwin is using in the tutorial. As for compiling to that pointer access: fro

Several investment banks are using these languages in production (BarCap (F#) and Standard Chartered (Haskell) are the names that come immediately to mind). And of course Minsky's employer, Jane Street Capital, writes everything in OCaml. T

It is unfortunate that those of us who are not US citizens are going to be negatively affected by the blackout but are unable to take any effective action against SOPA/PIPA.

Simon has been doing a ton of work behind the scenes getting a decent curriculum in place for computing in the UK, playing a major role in a group of educators tackling the issue. I would not be surprised if Michael's words were lifted di

The Glasgow Haskell Compiler uses tagged pointers to implement lazy evaluation. Suspended computations are created as heap-allocated "thunks", and the runtime will tag any pointers to a thunk that is known to have already been evaluated, wh

I can beat Very Hard opponents with ease but am stuck in silver :-). Furthermore, he states that his AI is weak to early agression. This is not a problem for him because the builtin AI never cheeses, but it happens all the time on ladder an

Do they actually claim that? Their page claims that 50% of household energy usage is governed by the thermostat, but they are very careful to avoid any specific claims about how much Nest would reduce this usage.

A 5 page paper by a previously unpublished author with no associated institution? How does this have any credibility?

This is pretty arcane even for Haskell aficionados. I have no idea what it is doing on Hacker News.

CoinStar in the UK/USA does coin counting+cash out for free as long as you turn coins into a gift certificate. Perhaps there is something similar where you live, it may be an alternative to the bank?

I think you mean Resolver Systems. The web based spreadsheet is not their "core" product, though: they started with a desktop spreadsheet app.

Due to how round-off is specified, cumulative errors in floating point calculations should average to 0 for typical workloads.

This guy appears to be a well-known troll, which is supported by the incoherent nature of this article and the rest of his blog: http://let.sysops.be/wiki/Richard_Kulisz

Basically what is going on here is that the system is recompiled to pass floating point numbers in the ARM VFP registers, rather than the integer registers. This both reduces register pressure and means you don't have to marshal stuff to an

They aren't alternatives: spam is network IO bound, mining is CPU bound. The smart bot herder would do both. The main danger is that the target notices that their machine is using 100% CPU and removes the bot. It is easier to notice CPU loa

There are 21 million bitcoins and they divide down to 8dp, so you need 16 decimal digits to represent them exactly. Coincidentally (?) double precision floating point is capable of precisely representing exactly 16 decimal digits. http://e

My father-in-law is a Chinese millionaire (in GBP terms) and wouldn't dream of emigrating. The things that tie him to his homeland are all the usual elements: shared culture, shared language (very important, as he can't speak English), a hu

Why is it that people support secret ballot, but not secret donation? Both are forms of political support, and making them public can in theory prevent people from expressing their true views. So why is the secrecy of one protected, but not

For another perspective: USD are "hoarded" by investing them in US treasuries. This preserves their value against inflation, because (to a first approximation) when the Fed prints money it does so by buying those treasuries, thus raising th

You can implement "finally" as a higher order function in Haskell: finally :: Either err a -> IO () -> (a -> IO (Either err b)) -> IO (Either err b) finally (Left err) cleanup _k = cleanup >> return (Left err)

It's hardly unusual for entities that receive government money to also charge for products/services produced using that money. Three examples I can think of just off the top of my head include 1) the health service in places like France whe

If you aren't interested in supporting call/cc or other control-transfer constructs like exceptions it might be easier to just use ANF. See Kennedy's "Compiling with Continuations, Continued" for another perspective on the ANF/CPS choice:

Yes, the title is confusing. GHC 7.02 is significant because it will be included in the next Haskell Platform release -- GHC 7.01 was only available separately, and was not much installed. GHC 7.01 was also a time of upheaval in the code ba
