It's in the works: https://code.google.com/p/v8/issues/detail?id=811 You can tell by the number of CLs that a lot of work has been done already but there are a few more still in pr…

I've been going back and forth on this. On the one hand, I feel that positive discrimination is just as bad as the other kind and that its proponents are not thinking things throug…

Interesting results, thanks for sharing. I can perhaps shed some light on the performance differences. > Buffer 4.259 5.006 In v0.10, buffers are sliced off from big chunks of pre-…

Libuv author here. Libuv doesn't try to be all things to all people - its main users are Node.js and Rust - but if you have suggestions on how to improve the API or the implementat…

On and off kernel hacker here. Compile and test the release candidates Linus puts out every fortnight. When the inevitable breakage happens, use `git bisect` to track down the offe…

That's a regression we'll probably have fixed in 0.6.1. Note that I/O read performance is up 35%, from 19.7 mb/s in 0.4 to 26.6 mb/s in 0.6.

I suspect that it's a jab at ALSA which, for reasons unknown, ships with a full LISP interpreter[1] that it doesn't actually use... Lennart Poetering is the author of PulseAudio. H…

> Isn't Node.js single threaded ? Yes (for now, we might take up V8 isolates). > Would it not under-perform , say compared to Erlang or Netty, in a multi-core CPU. No. You can spin…

It's been fixed in master. 0.5.2 comes out tomorrow (if all goes well) and will also contain the fix. https://github.com/joyent/libuv/issues/112 for details.

linux doesn't have kqueue. But kqueue is only an API, you could emulate it with io_submit() and io_getevents(). A bigger obstacle is that not all file systems support asynchronous …

That was the impression I walked away with too: much CS ivory tower thinking, little real-world relevance. But they're only interviews, everyday life at Google is probably (hopeful…

There isn't a shred of the original mongrel parser left. I'm not 100% sure but http-parser looks more like it's inspired by nginx than that it actually contains nginx code. Disclos…

Maybe I can help. I'm relatively local (Gouda, ZH) and I've managed teams like the one you mention before. Shoot me an email, address is in my profile.

The language was C and my solution (adapted to the article) was something like this: // TODO enforce! see also: soylent green #define MAX_AGE 100 struct student { const char *name;…

> His grandmother knew radix sort. Radix sort? I read it as a trick question where the answer is 'hash table with numberOfYearsOld as the key'. I suggested that as the solution to …

Sounds about right. My base salary, no benefits, would be about 58K a year if I worked full-time. This is in Rotterdam, where salaries are slightly lower than in Amsterdam.

I hear you, threading in SM is indeed fraught with dangers. On the off chance that you're going to revisit it, the way to go is to compile with -DJS_THREADSAFE and register a callb…

V8 is a single-threaded VM and I don't see that changing any time soon, it's very much married to Chrome's per-process model. SpiderMonkey doesn't have that drawback, it supports t…

You'll be hard-pressed to exhaust all ports: modern operating systems track connections by source address + source port + target address + target port. I wouldn't be surprised if t…

Take the staged approach: 1. Begin with a simple JDBC-backed servlet + JSP web app, like a blog (boring, I now), and deploy it to a servlet container like Jetty or Tomcat. 2. Migra…

Sounds promising. Is remote an option?

> Don't things like real time linux or soft real time patches for linux help, though ? I don't see how it could. The CPU essentially drops everything it's doing when a packet comes…

The problem is that a high-bandwidth link overruns the CPU with thousands of interrupts per second. It can paralyse the system, where the CPU is so busy handling I/O that it doesn'…

No. The main problem the event MPM addresses is HTTP keep-alive. With pre-fork and threaded, every connection takes up a process or thread. This sucks for keep-alive because it can…
