A long time ago, I administered a decent-sized Big Brother
installation. I wrote a number of extensions and patches and released them into the wild. They're completely unmaintained and unsupported any more but if you use Big Brother, they may be of use to you. There may be more than what's listed here but these are the ones I remember writing. [Roughly sorted by usefullness.]
At one point, I was my company's primary MySQL DBA. I had the opportunity to work with some challenging databases (I never lost one row of data that the client didn't tell me to get rid of!)
- rw-ratio - I wrote rw-ratio so I could gauge the read and write activity of some MySQL databases I was managing.
I eat, sleep, breathe Linux.
- file2dev - I wrote this so I could easily identify which device a particular file or directory was on.
