Not for a couple of months - I need to get my startup in beta first, but the sysadmin tutorial site is next on my to-do list.

I read the "stracing ls" article (I think it was posted here), which was fascinating reading. I am planning to write higher-level tutorials rather than dissecting low-level commands, although now that I think about it a mix of the two would be better.

Thanks for the feedback - if there are any specific areas you would like to see covered do let me know, and I'll do my best to include them.
