Disaster recovery

So the last 24hrs has been spent mostly recovering from disasters. The electricity was switched off recently at my flat which managed to take down my little arm server. For some reason it didn’t come back up when the power was restored so had to be manually rebooted last night. This turned out to be an exercise in futility as for some reason icedove (debian version of thunderbird) wasn’t showing any mail folders on my mail server. I ended up having to delete the server resync everything and recreate my mail filters which wasn’t fun.
After this I’m kind of toying with the idea of building a backup power system for it. It should be relatively simple as I can just float charge a SLA battery and use switch mode regulators to provide 12V and 5V outputs for my NAS and home server. I can also use the unregulated 24V from the battery to supply power for my next version of my tube time displaying clock next to my bed.
Of course this wasn’t the only fun to be had as I also had a flat tyre on the Brompton coming into Kings X. I ended up sitting on the floor by the doors on the train with a dismantled back wheel of a bike. The back wheel on my bike is especially bad as to remove it you have to take off the chain tensioner and disconnect the hub gear cable (which then needs to be readjusted or you can’t change gears properly). I did better though then last time I had to change the tire and my tirelever combined with spanner thingy saved the day again as I only needed one tool and it’s a metal tire lever so doesn’t snap (though it is coated in plastic).
