Virtualenvs with different interpreters

Update 2011-09-27: Turns out virtualenv and virtualenvwrapper support this out of the box. Most of what’s written below is horrifically complex compared to just using the -p switch when you make your virtualenv. You simply need to do this:

$ mkvirtualenv -p /path/to/some/python coolname

That’ll create a new virtualenv called “coolname” that uses /path/to/some/python for it’s Python interpreter. I’ve tested this with PyPy and it worked great.

SSH Agent Forwarding

This is part of the mini-series OpenSSH for Devs.

SSH agent forwarding let’s you lock down remote hosts while making them easier to access and use in automated ways. One co-worker succinctly describes agent forwarding as “the shit”.

SSH Config

This is part of the mini-series OpenSSH for Devs.

An SSH config let’s you set options you use often (e.g., the user to login as or the port to connect to) globally or per-host. It can save a lot of typing and helps make SSH Just Work.
