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.

What others think

Use the value 0 for the -m switch to get max space for all users.

warning: don't use '-m 0' on the same filesystem as the OS (ie. where /var or /tmp is mounted). The point of reserving space for uid:0 is to make sure that system-maintenance daemons can still get work done when the users are getting "no space left on device" errors.

Otherwise, it's a good idea for filesystems you occasionally mount, like portable harddrives on USB.

Ah, the joys of the ext-based family of filesystems. You don't get this crap with ReiserFS, BtrFS, XFS or JFS. Any ext4 filesystem I create gets "-m 0" by default on all filesystems.
