I've been messing around with SVN, trying to set up a WebDAV service to stash some drupal themes in. I keep screwing up the initial import at which point a quick round of rm -r /var/svn/rocksoc && svnadmin create /var/svn/rocksoc and I'm back to where I started. Intill I take a break for lunch and have a brain fade and type rm -r /var/www/rocksoc

Opps

It's a really good job I keep backups

Ever shutdown/rebooted the wrong machine through ssh+carelessness? molly-guard comes to the rescue, asking you to type the hostname of the machine you intend to shut down if it detects you are connected by ssh. It's packaged for and available in the main repositories Debian and Ubuntu, I don't know about any other distros.

An example:

[sudo] password for charles:
W: molly-guard: SSH session detected!
Please type in hostname of the machine to reboot: lucifer

Overly hot hard disks are bad. I think we all know that. It doesn't stop us worrying about our data, but a problem can't be fixed unless we know it's a problem. Opening cases and touching hard drive to see if they are hot is the most low tech of approaches, but it's cheap and completely cross platform.
