You got me all excited about having some fun in the rain over the weekend and then I learned that the Home Office has classed Potassium Permanganate as a drug precursor, so you have to fill out half a ream of paper before you can buy it.

I'm now weighing up whether it is better to appear to the authorities as an anarchist, a terrorist or a drug maker.

At least ping pong balls are still readily available...

Back when the Amiga 500 roamed the earth, I pondered long and hard whether it was possible to send a voice signal over a serial link by breaking the signal down into it's component frequencies, sending the resulting spectrum over the serial line, then reconstituting it at the other end. Which, of course, isn't a million miles away from VoIP as practiced today.

I also did some work in school with pendulums, the teacher said we could use our own measurements, by which he meant cm or inches. I measured everything based on the length of the pendulum long before I'd heard of algebra or things like pi. This flash of inspiration was dulled somewhat when I decided to call me new unit of measurement a "cooler meter"

(oh and I wouldn't be breathing it in, it's pretty nasty)

I can't lay claim to getting anywhere with diffs on my own though. It also took me far too long to work out that the egg-milk bottle trick only works if you take the shell off first.
