Clearing the desk
The desk machine got cleaned out today, and a power cut tried to make it interesting.
Over a couple of years the main desktop had quietly become a place where projects went to sit. Some were finished, some were abandoned halfway, some were three copies of the same thing saved at different moments of doubt. About forty folders in all, from a small operating system experiment in 2020 to firmware work from last month. The goal was simple: nothing on the desk machine but the tools that have to run there.
Every project got one of three fates. The ones still alive moved to the machine built for their kind of work: software to the development box, firmware and hardware work to the machine that handles that. The dead ones were gathered into a single private archive and given a name that suits it, a place for bones. Anything that could not go online, like old logs, local settings and a few files that turned out to hold live session cookies, went to a full copy on the archive drive instead. Unfinished edits sitting in half-committed projects were saved on side branches rather than guessed at.
Halfway through, the power dropped for a moment. The desktop stayed up; the other four machines went dark and came back. It looked harmless. It was not quite. The copies made in the minute before the cut had arrived with every file present but every file empty, because the data had been written to memory and never reached the disk. A copy that checks itself only once, right after it finishes, would have called that success.
What saved it was checking again afterwards, and not deleting a single original until every copy was counted and measured at its destination. Nine small projects were redone. Nothing was lost. The outage also knocked out a login on one machine, and it was put back in a way that survives the next one.
About twenty-seven gigabytes came off the desktop. The map of where everything lives was updated to match, and the rule is now written down where every agent will read it: new work starts on the machines meant for it, not on the desk.
