After about 4 weeks into my first programming job (~15 years ago), I lost all the source files in my cwd by mistakingly typing "rm *>o" instead of "rm *.o". Of course at that time there were no tape no backups and my last commit was about a week or two earlier. I went to see the sysadmin and explained my situation.
In about 2 minutes he wrote a C program that opened and read from/dev/hda in blocks, looking for some variable/function names that I had provided him. This yielded a big text file, and it took me about a day to untangle and reconstruct the various source files. I remember that had impressed the hell out of me.
One book that blew my mind was "The Data Warehouse Toolkit: The Complete Guide to Dimensional Modeling" by Ralph Kimball. It's pretty easy to read and offer some very interesting techniques for designing data warehouse schemas.
- Run your services in a few vservers on the same physical server:
* DNS + DHCP
* mail
* ftp
* www - Have a backup server where your stuff is rsynced daily. This allows for quick restores in case of disaster.
Vservers are great because they isolate you from the hardware. Server becomes too small? Buy another one, move your vservers to it and you're done. Need to upgrade a service? Copy the vserver, upgrade, test, swap it with the old one when you are set. It's a great advantage to be able to move stuff easily from one box to another.
I had one of those FM transmiters and it was a horrible experience. Since my van still has a cassette player, I bought one of those fake cassettes that has an input jack attached to it. Sound is not bad at all and it plugs right into the iPod headphone jack.
I can't count the number of times I was driving and wished there was a button on my steering wheel that I could use to shoot at the moron in front of me...
For those of you interested in running many Linux hosts on one physical machine, check out the
VServer Project.
With it you can run many Linux environments using the same kernel. It provides process, filesystem, network and resources isolation levels.

hmm,
That gives only the strings, I needed the entire text blocks to reconstruct the source files.

Here's how we do it:

Anyterm is what you want: http://anyterm.org/
It's basically a terminal with a Javascript front-end. Pretty cool...
