A couple of months ago, I transfered the website engine from wordpress into Octopress. A lot of errors were found in previous posts due to format incompatibility, especially some perl scripts.
Please read carefully before using any code or script, and leave a comment if you find some “terrible” error.
[update-2013-08-08] now only perl howto related posts
[update-2015-01-01] All format issues are (putatively) resolved.
