Re: [ANN] Luvit - Lua + UV + Jit = NodeJS re-implemented in Lua

[Tim Caswell <tim@...>]

Right, I keep forgetting to mention luanode.  I don't mean to slight Ignacio.

First, the reason I made my own instead of contributing to his project
is my goal was to learn libuv and lua bindings.  What better way than
to re-implement node in lua using libuv.  Now that I've done most the
prototyping, I've gotten busy with work and moving and other stuff so
I'm presenting my work to the community to see how it stands on it's
own.

Luanode is probably more mature and certainly been around longer.  It
uses C++ and Boost ASIO.  I use C and libuv which is the exact same
library used by node itself.  I haven't benchmarked luanode at all so
I can't speak for it's performance.
