Defibrilators are interesting. Electrical devices to shock people. Like a taser with medical credentials.
I'm told that you should not use a defibrilator by a swimming pool - and throwing the thing into the swimming pool is a bad idea. Yes: I asked. Had to. The answer was quite emphatic. (And …
Thanks to a bit of carelessness with a cup of coffee, I managed to drown my personal laptop. And waste good coffee in the process.

In the last blog post I ruminated a bit on calculating the best place to fill up and got a plausible result. But the chosen metric suffered from a couple of flaws:

Petrol has gotten more expensive, so we all drive less than before. Which raises the question: "When is the best time/place to fill petrol?"
