What can we do with node.js, socket io or any server side JavaScript?
I know every programming language or framework has its own features or functionality that makes it different from other. For example, we use jQuery specially for nice UI design. On that view, what is necessity of learning node.js?

I have a very light grasp of the Rx framework and while I understand some of its capabilities, I'm not sure of where it makes sense to use it, especially in a "real-life" scenario e.g. a distributed Web app.
Do you use Rx? Which version? What for?

I'm writing a web server using libebb (http://tinyclouds.org/libebb/) and libev. I'm looking for an async httpclient that uses the libev event loop.
I'd like it to support Http 1.1 (pipelining, keep-alives, etc).
I hope this isn't a dumb question.
Here is an HTTP client I made using libev and C++:

In PHP the best choice is nginx now,what's the case in perl world?
Nginx is still a fine choice, but if you write your Perl app to be PSGI-compliant, then you really shouldn't care; changing web servers is a snap.

I'm making a GTalk client for iOS and would need a XMPP library to do the heavy lifting.
Anyone know of such?
There's a single Objective-C library (xmppframework) listed on the XMPP Standards Foundation site, although if this doesn't prove to be suitable you should be able to get the C/C++ libraries up and running with some wrangling.
