Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

This is great for looking for files that have been updated recently. Logs especially or monitoring what files were added during an install.

The time is expressed in epoc but is easy to use any other format.
Deletes files older than "n" minutes ago. Note the plus sign before the n is important and means "greater than n". This is more precise than atime, since atime is specified in units of days. NOTE that you can use amin/atime, mmin/mtime, and cmin/ctime for access, modification, and change times, respectively. Also, using -delete is faster than piping to xargs, since no piping is needed.
If you can do better, submit your command here.
