I decided to treat myself to a new battery for the bike. I have two good batteries; of which one needs a lot of babying. And three batteries that are pretty much knackered, good for maybe one mile. So I did some research - can I put new cells in a knackered battery? It looks difficult. So I looked at the cost of a new battery, and it turned out that buying from alienocean.co.uk (who, I have to say, look like *the* e-bike supplier in the UK) is about the same cost as importing from China or Spain, if you include carriage cost. So I bought from them, no fuss, no hassle, battery arrived in two days. Sorted.
One of my key servers stopped working. I have an alerting system that tells me about such things, and it started sending me emails. So I hastened down to the Data Center (my garage) and smelled burning. I pulled the server off the rack, and it was clear what had gone wrong - the power supply. The fan that is supposed to keep it cool had locked solid (they do that after several years).
I replaced the fan, and the power supply worked ... until I plugged in the hard drive, and then it died. Well, it isn't worth trying to fix a power supply, they're so cheap, just a fiver or so. So I replaced it, and everything is working fine now.
