nextTick is the efficient way to yield to another thread of processing
(thread between quotes of course) when performing an expensive computation.
So it is the antidote to starvation and thus a very useful call.
If you change its behavior, you should at least provide a replacement call
Just wrote a quick bench: https://gist.github.com/2830638
Results:
Benching setTimeout
elapsed: 15593
Benching nextTick
elapsed: 2226
So, there is a penalty in switching from nextTick to setTimeout: the call
is 7 times slower!

I don’t understand why you’d want to use process.nextTick() for that, or
indeed, any similar API. The API you want is “do this work in a separate
thread/process/other schedulable unit that the operating system knows about”.
From: nodejs-dev@googlegroups.com [mailto:nodejs-dev@googlegroups.com]
so I guess in a way setImmediate(fn) could be described
fairly accurately as a faster setTimeout(fn, 0). As I understand timer
events get put at the end of the queue as well.

Hi list, yet another question (I know its getting much in the last days :-).
Suppose I want to host a second legacy website with Apache-PhP on my
VPS otherwise running awesome node.js (not my blog, its yet something
else). So I check request.headers.host and if its the VHOST for the
legacy
var httpProxy = require('http-proxy')
;
httpProxy.createServer(options, function(req, res, proxy) {
if(req.headers.host === 'whatever.example.com') {
proxy.proxyRequest(req, res,
{ host: 'localhost'
, port: '8080'
}
)
return
}
res.writeHead(400, {})
Thank you.
The thing that confuses me is, why httpProxy.createServer(...);
Cant I just create http.createServer() handle requests normally for
the main node site, and in my request handler create a proxyRequst
only when it relates the VHOST?

eval isn't evil, but it has potential for evil. using eval in for
configuration files is not bad, because you know what they contain,
after all, you are editing them by hand.
if you are sending JSON5 or eval'd js remotely that is probably a bad idea.

Async.auto() avoids this problem, since you always have access to 'results'
hash object that contains results of calculations, and you can access them
by name.

Hi Thijs,
If I recall correctly, JSON-RPC (any version) doesn't have named parameters,
this is an extension on the spec. There are (were) a few explains of this being
