Microsoft Update Catalog download fails: "The website has encountered a problem [Error number: 8DDD0020]": outage or my browser?

Scope that carefully before it becomes estate-wide policy. "Allow insecure content" is exactly the permission your security reviewer will ask you to justify. Set it for catalog.update.microsoft.com only, on the admin workstation only, and take it off when the patch cycle is done. Do not push it as a browser policy to the fleet because one popup annoyed you.

Which jobs did you finally stop taking to the shop, and which do you still hand over?

Things that moved home permanently for me: gear cables and indexing, brake pads on both types, tubeless setup and sealant top-ups, bottom bracket removal on threaded frames, and headset servicing. Things that still go to the shop: wheel building and any serious truing, facing or chasing a frame, pressing headsets, and suspension internals. The dividing line is basically whether the job needs a tool that costs more than the job, or a tool that damages the frame permanently if you use it wrong.

Whole house is already HomeKit, is there a real reason to move to Home Assistant rather than just running Homebridge

Practical numbers from running both on the same little box: Homebridge idles at almost nothing, Home Assistant with a database and a handful of integrations wants real memory and writes to disk constantly, which killed one SD card for me. Restore time matters more than idle load though. A Home Assistant backup restores in minutes, and rebuilding a Homebridge config by hand took me most of a Sunday.

how do you separate init time from handler time when the logs only give me total duration

when i did this on a service doing a few hundred thousand requests a day, roughly six percent of invocations were cold and they did not move the median at all. p50 was flat, p99 was almost double the warm p99, and the entire alert that started the investigation was one tail metric. knowing the cold rate told me whether it was worth engineering away, which for six percent it was not.

Interview audio has a low hum only on the lav, boom track is clean

Almost certainly induced hum rather than a ground loop, and the head-turning detail is what tells you. A lav cable running near mains, a dimmer, a fluorescent ballast or a laptop charger acts as an antenna, and body position changes the coupling. Fixes in order: find and kill the offending device, because dimmers are by far the worst offender, reroute the cable away from mains and cross it at right angles if you must cross, and if your recorder is plugged into the wall, run it on batteries instead. Notching 50 or 60Hz also mangles the harmonics, so five minutes at the source is worth it.
