UNIX Hedgehog

I got my employer to send me on a UNIX course this week - three days of finding your way around and two days of shell scripting.

I love this kind of thing - it's as good as a holiday. The last part will only be mildly useful at work, but it's great fun, if your mind likes to work that way. I already know that telling the computer what to do is just an amusing interactive mind-puzzle. The hard part is working out what you want it to do in the first place, as this man explained in 1986. That hasn't changed, and it's not going to, ever.

I shall return to work refreshed.
