IIRC Servo is using html5ever for HTML parsing, which (at least in one branch) uses SSE4.2 for parsing.

So, do you consider the Go1 compatibility guarantee to be a mistake? Most suggested stdlib or lang improvements are DOA for the time being as a result, which is annoying, but of co…

I read that they have static analysis tools to track the flow of Contexts, making it much easier to verify that Contexts are threaded through correctly, which can make things a bit…

From that, it's not too hard how people could think it was influenced by Go (though it apparently wasn't): http://play.golang.org/p/oWNRd0D2Zp looks superficially very similar

There is a GSOC to add escape analysis ( https://www.google-melange.com/gsoc/project/details/google/g... ). It'll be interesting to see how that affects things.

Yes, in the same sense that any language with first class functions can. So, like: var SomeFunc = RequireAuth(func(...) { ... }); However, there's no language-level support, so you…

If I'm not mistaken, Plan9 comes with a code formatter, and this idiom is common in Plan9, so it seems likely that it is supported. http://plan9.bell-labs.com/sources/plan9/sys/src…

I somewhat disagree. Even if you don't use channels as iterators/generators (which many folks do), it's not hard to end up with a goroutine blocked on a channel that'll never be cl…

You can leak memory by leaking goroutines. If a goroutine is waiting on a channel that nobody else has access to, it lives forever, as does the memory it references. So, you can pr…

According to Last Call by Daniel Okrent, Gough St was named after famed temperance orator John Bartholomew Gough. I'd assumed that was true until I saw this site. Wikipedia has sup…

Why should C and Go (AOT compiled) be faster than Java for pure integer numerics? For long-running simple tight loops of numerics, I'd assume HotSpot would be faster.

I agree with them on the readability issue mostly, but I don't understand the preference for parens-less function calls, especially where there are arguments. Maybe it's a matter o…

If you don't care about types, schemas, and schema changes, probably not.

Also, segmented stacks ( http://llvm.org/releases/3.0/docs/SegmentedStacks.html ). GCC already supports it.

My "ah ha" moment with Haskell was after a few years of using it quite regularly, I realized that it wasn't actually making me more productive in the kind of code I actually write …

Does the answer here make sense to you?: http://golang.org/doc/go_faq.html#creating_a_new_language

I don't think the spike in VM means it's paging all that. That just means it has that address space reserved, not that it's using it. I'm not aware of any real cost to having a hug…

It doesn't sound like you're using the benchmarking tools that Go provides; I'd recommend using that if you're not. Ah, yeah, I was testing a much much smaller byte array with mult…

For what it's worth, I've looked into the 'Split' case, and the performance difference when specialized to the single-byte case is about 2%, which is mostly because Split already h…

It is quite neat and mighty convenient, but I sorta live in fear that at some arbitrary point the library will change and my code will just stop working. I konw this isn't a proble…

FYI, the original article has been updated with graphs showing reqs/sec, virtual, and real memory for both using 100, 500, and 1000 simultaneous requests. Aside from virtual memory…

For comparison, what do the automatically generated XML versions of those JSON examples look like?

It certainly could be more optimized. For example, all numeric literals are converted to strings before being parsed. That's a mostly unnecessary copy/allocation per number. Simila…

Would the comparison be more fair if the Python/Dart code were mapping the JSON to an existing type?
