Cross-compilation-safe FFI for a pre-compiled C library that must ship dormant and activate at runtime

Status: Problem statement for Go-team review, not a proposal. It stops deliberately at "here is the problem and who it hurts"; candidate solutions will be filed separately.

Summary

The model switch that cost $2,300

I switched models once, in the middle of a long coding session. Same repo, same task, same tools. I did not change my prompt or my workflow. Then I switched back.

The session kept a record of all three phases, which turns an anecdote into something closer to a controlled experiment:

phase	model	requests	cost	cache hit	uncached input per request	compactions
1	`gpt-5.6-sol`	184	$88.02	97.3%	3	0
2	`gpt-5.6-sol-pro`	608	$2,150.73	56.0%	229,499	23

iOS Live Photo `.MOV` that's actually a JPEG: where it comes from (#24763)

Follow-up to my earlier writeup (https://gist.github.com/eliottness/0a2cb17ddf578ab619d7b3f693ed2787), which proved the stored "video" is really an HDR MPF JPEG. This one is about why it happens, with the actual code paths, and where a fix could go. I read through the current main mobile and server code for this. I haven't been able to test on a device yet, so I've tried to separate what I'm sure of from what I'm inferring.

Quick recap of the symptom

iOS Live Photo `.MOV` is actually an HDR JPEG (MPF + gain map) — investigation

Related to immich-app/immich#24763.

Symptom

Some iPhone Live Photos uploaded through the iOS app show their ~3s "motion" clip flashing black and white in the viewer. The still looks fine; the video portion cycles colour → grayscale → black.

WSABuild on Windows 11 25H2 — Full Debugging Report

Date: 2026-06-26 System: Windows 11 25H2, build 26200.8655 (retail), driven entirely from WSL2 via powershell.exe Subject: WSABuild 2407.40000.4.0 (community Windows Subsystem for Android, Magisk + MindTheGapps) — Google Play Store never appears after install Outcome: Root cause identified — a build-level incompatibility at the WsaService→HCS activation layer. Not fixable with current community tooling. WSA fully removed at user request.

TL;DR

Bitwarden SSH agent in WSL2 (via systemd)

Use the SSH keys stored in your Windows Bitwarden Desktop vault from inside WSL2 — ssh, git, ssh-add, etc. — managed by a systemd user service instead of a fragile .zshrc snippet.

This bridges the Windows OpenSSH-agent named pipe that Bitwarden exposes (\\.\pipe\openssh-ssh-agent) to a Unix socket inside WSL using npiperelay + socat.

AMD Ryzen Zen 3/4 — Random Reboots: Data Fabric Sync Flood (0x08000800)

Symptoms

System reboots randomly every 1–4 days with no warning
No kernel panic, no OOM, no visible error before crash
last -x reboot shows all entries as crash (never a clean shutdown)
On next boot, kernel prints:

	unset LD_PRELOAD
	export LANG=fr_FR.UTF-8
