It is truly disheartening to see you'd been downvoted when I came into this thread. The truth is, the OP's domain was probably considered to be in a bad "neighborhood" because his mail server had been compromised for spamming purposes at

It's close to the same thing, but having more named registers does provide more optimization opportunities. It shouldn't be completely ignored as a good thing. I mentioned function calls because that's a boundary when an optimizer - either

Yeah - the vast majority of x86 assembly written today is written to take advantage of specialized instructions that aren't available in this VM.

The instruction set is vastly simpler than x86, but it does inherit some limitations for no reason. x86 had 8 named registers for so long because the mod_rm byte in x86 only has 3 bits for each operand. Adding the REX prefix byte in x86=64

I'm sorry? Python is the same way: >>> i = 10 >>> def x(): ... print i ... >>> x() 10 >>> i = 11 >>> x() 11 The value is not closed over

But what I pulled out from the Wired article amounted to "it's silly that if the file sizes are slightly different you need to upload your whole song." If file sizes are different, the MD5 will be wrong in nearly all cases. They're talking

You've repeated the burrito example in nearly every subthread here, which is poor form to begin with, and it is a horrible example. You are comparing ("chicken burrito" -> "beef burrito") to ("something with words I've never seen in the

Russ is pretty much describing Go as it existed in its developer's minds in 2007. He even explains nearly all of Go's (future) interesting features - with nearly identical syntax - before he even gets to an example.

Not having int64/uint64 is kind of a deal-breaker for any such library. Which means, in JavaScript, a big integer library. I don't see one.

This seemed like a developer-targeted article, though. I mean, who is having trouble with even 1 million directory entries, let alone 8 million, who is afraid of a compiler?

You've done an excellent job of summarizing why Google does what it does: extremely few languages, and all code must pass readability review (or be written by an author with readability for the language(s) used) before it can be committed.

If string processing is a bottleneck in your system, either your system isn't doing anything else interesting to take up CPU time, or you've done something very, very wrong. Serialization is a damn-near solved problem.

Monads, in the context of programming, are used as abstractions for computation. That's all - some people mention state, because some useful computational strategies maintain state - but not all do. In Haskell: The List monad represents non

My undergraduate thesis tackled static analysis in Ruby. One of the problems I attacked was "does a given method yield to its block?" I broke methods into a few classes, two of which are "Block-Required" and "Block-Optional." I had to write

It's a matter of purity inference. They already trivially know the value isn't used based on the AST, so they need to show that the function being called is pure to elide it. Naturally, in the general case this is undecidable, but there are
