I really wish us open source geeks would get a clue and do better technical documentation, glyph linked to his girlfriends Amazing tutorial on setting up a development environment for the twisted and divmod.
Well, specifically, a Windows development environment. From "How to install SVN" to "How to get the Emacs customisations up and running." With screenshots of more technical things (Yes, to a windows user, using cmd.exe to install a python lib using distutils is technical, there's no GUI for this).
Colour me impressed. I especially like how no assumptions are made about the existance of tools like "something to decompress bzip2." Far too many tutorials I've suffered through have had glaring omissions of basic tools that you are assumed to have.
