Tonight the sheevaplug died, sending napalmpiri.openssl.it down. Dead cold. I suspected at once a PSU issue, and that turned out to be too true.
Warning: twiddling with the PSU means dealing with electricity at dangerous voltages. It involves a dangerous hot soldering iron. If you are not skilled these things may conjure up and ruin your day. Or you may burn down the house. This is not a joke. If you don’t feel confident, just buy another plug.
Unfortunately Globalscale technologies gives only a 30 days warranty, so I was basically stuck.
I think that the sheevaplug, from the hardware point, is really flaky. It may be good as a developer tool, but it’s just too flaky even as a home server.
