command log
Thursday, July 31 2025
I made great progress with that database backup utility I'd started on yesterday. By the end of the day, I even had a fairly clean interface. Best of all, now I knew how to create utility apps in dotnet, that is, for Windows machines. That's a skill I've wanted to have for at least thirty years but never really did.
In other software development news, today I added a logging system for my "instant command" system, a sort of hacked-on ability to interactively communicate with my remote ESP8266s using a system similar to a Unix shell. It uses a complex system of temporary files to pass messages to and retrieve them from the ESP8266s, though it just logs the resulting messages into a textarea on a web page. Once I started logging the actual commands in a database table, I realized I could also capture their results in that same table. And once I did that, I could completely dispell with the crude text-area logging. Now I could just display a dump of the command_log table, showing a "waiting icon" (simulated with CSS) for commands that had yet to produce a response. It was suddenly a much more polished system.
Meanwhile, heavy rains came through the area. These resulted in serious leaks from the skylight in the topmost apartment at our Downs Street apartment, giving Gretchen a new headache. We'd recently replaced the roof on that building, but hadn't actually addressed the small section of flat roof in the center where the skylight is. While waiting for someone to price out fixes, she gave the tenant a $150 discount for the month.
In other landlording news, our tenant at the Rochester house unexpectedly announced that she will be moving out soon, meaning that now Gretchen had to find a replacement. This is a breaking of the lease, so we'll be getting $2000 for the trauma, but it's another headache for Gretchen. Ironically, we'd just been telling our friends Greg and Z that our real estate empire has been painless to operate of late.
All the rain kept me from taking the dogs for a walk. My pavlovian response (dating to when I was kid and our family depended on rain for potable water) was to want a bath, which I ended up taking. The weather had cooled down significantly and hot water did not feel unpleasant.
