Windows.

Linux.

Unix (YEAH!)

Back in MY day we didn't have all these fancy things. Nossir! We programmed on a manual typewriter and sometimes with a pencil! And we didn't have these fancy-schmancy ones and zeroes, either. No! They hadn't been invented yet. WE used lower-case ells and ohs and when I FIRST started we only had lower-case ells because they were still creating the alphabet! And my programming prof remembered programming by whacking two rocks together, and she said that was an improvement over programming with smoke signals! And we did it in machine code, too!

You guys today are wimps, that's all. Wimps...grumble...grumble....
