Father of Unix Ken Thompson checkmated: Old eight-char password is finally cracked

Re: I have to thank ken for my passwords

Many years ago, late one night, I was working on a make file. Tired, I used a path something like '~/temp' in the make file. Ran make, then did an ls. I noticed that there was a directory called '~' in the directory that I was building in. So, figuring out that '~' isn't automatically expanded in make files, I rectified the mistake and then, to get rid of the mistakenly created directory I typed: 'rm -rf ~', and hit enter.

It seemed strange that it was taking so long to delete a few temporary build artifacts. A few minutes later (remember that I was very tired), the command was still running. A couple of minutes after that, I realised what I'd done. Just about to Ctrl-C, and the command finished.
