@corbet @lwn I ended up disabling the selinuxproject.org wiki & redirecting it to the github repo. That was after a bunch of anti-crawler stuff was enabled. It's too much to meaningfully keep up with as a hobbyist.

@etchedpixels the technical arguments re. behind the meter efficiency are surprising to me. They mention an attached report but I didn't see it. In any case, they say the power demand drops 1% for 1% voltage, which seems to point at efficiency of appliances which convert voltages down. Fix those instead? I also wonder if they've looked at the impact of increasing the max current draw for the same power, increases in copper losses and increased risk of fire via house wiring & switches.

Spent an eternity today retuning a 10-pole cavity filter. Started to feel like I was in an episode of Severance, manipulating patterns by intuition on 80s tech.

Doh. Just discovered the 'up' alias for upgrade in dnf. I have wasted so many keystrokes.

@bagder I thought you said “exhausting nothingness” for a moment and I think that also fits generally.

picolibc has been reformatted with clang-format. All PRs will now be checked to make sure they are formatted correctly, so any pending requests will need to be fixed and resubmitted. I'm looking forward to having only one coding style to deal with.

Thanks to all of the picolibc contributors over 2025 and best wishes for 2026.
