Ah yes – finally – blog post time again :) Since I am currently writing a lot of latex with vim I thought I backup share my ~/.gvimrc on my blog: 1 2 3 4 5 6 7 8 9 :setlocal spell spelllang=en_us " enable spell checking (Ctrl x + s for suggestions) :set wrap …
I started to roll out puppet to manage our servers at work and have to say I am impressed. It really changed the way I think about managing systems and is so much cleaner and easier to understand than the ‘traditional’ way.
