Getting Started with Edge.js

Quote from site :

Edge.js is a node.js module that let’s you run C# code from Javascript or vice-versa. It even works on
OSX and Linux through Mono. This essentially lets you write native addons in C# instead of C.

Running multiplie Python apps with uwsgi and nginx

Quote from site :

This is a recipe on how to easily run multiple Python web applications using uwsgi server (in emperor mode) and behind nginx. Most existing docs and blogs would show how to manually start uwsgi to run a single app. In this post, I'll show how to configure uwsgi as a system service (with upstart) capable of serving multiple python WSGI compliant web applications by simply placing them in a standard location and adding an standard xml file.
