gcloud keeps "signing out"? It's the hidden 16-hour Google Cloud session default

If your scripts, cron jobs or AI agents start failing with this a few hours after a successful gcloud auth login:

ERROR: (gcloud.projects.list) There was a problem refreshing your current auth tokens:
Reauthentication failed. cannot prompt during non-interactive execution.

ChatGPT Business: custom MCP app can't be published to the workspace (403 `plugins_access_denied`, 502 on sharing)

Observed 2026-10-16. Reported to OpenAI support; unresolved at the time of writing. Identifiers are replaced with placeholders (<workspace>, <app>, <plugin>).

Setup

ChatGPT Business workspace with two seats. I'm the owner and admin.
A custom MCP server connected through a Secure MCP Tunnel and added as a custom app in developer mode. It starts life as a personal draft.

Getting `bambam` (the baby keyboard toy) working on Wayland

bambam is a lovely little "keyboard masher" game for babies and toddlers: they bash the keyboard and mouse, and instead of emailing your boss or closing your windows, the screen fills with colourful shapes, letters and sounds. It grabs the keyboard/mouse so the little one can't wreck anything.

Install is a one-liner on Debian/Ubuntu:

Gerber Prime 6000 / PSC05 — local control cheat sheet (no cloud)

Controlling a Gerber Prime 6000-series smart-home controller (relay / shutter DIN-rail box, "Home Mate 2" app, config Wi-Fi named PSC05-<mac>) locally over HTTP, no vendor cloud. Reverse-engineered from its web UI. Full code + docs: https://github.com/danielrosehill/gerber-prime-6000-local-api

Defaults (vendor, from FCC manual)

Web UI / API: admin / 888888 (HTTP Basic)

Fixing OnePlus / OxygenOS auto-rotate that ignores the UI toggle (via ADB)

Problem: On a OnePlus device (OxygenOS / ColorOS), the screen keeps auto-rotating even though the Auto-rotate toggle in the UI / Quick Settings is switched off.

Root cause: The visible OxygenOS toggle and the underlying Android framework flag system.accelerometer_rotation can drift out of sync. The framework flag stays at 1 (rotation enabled) while the UI shows it off. OxygenOS's rotation-suggestion feature can also silently re-assert rotation behaviour. The fix is to set the framework flags directly with ADB.

Stop Chrome re-prompting for "global shortcuts" on every launch (KDE Plasma Wayland)

Symptom

On KDE Plasma (Wayland), every time you open Google Chrome (or Chromium) you get a permission prompt along the lines of:

"An application wants to use global shortcuts" / "Global Shortcuts Requested"

You click Allow, but the prompt comes back the next time you launch Chrome. It never sticks.

OBS Studio: "Couldn't initialize muxer" on Ubuntu 24.04+ / 25.10

If OBS Studio refuses to record on a recent Ubuntu (24.04, 24.10, 25.04, 25.10) with this dialog:

An encoder error occurred while recording: Couldn't initialize muxer

…and the OBS log (~/.config/obs-studio/logs/) shows:

[ffmpeg muxer: 'simple_file_output'] os_process_pipe_write for info structure failed

Conda Environment Strategy for AMD ROCm GPUs

Managing conda environments for AI/ML workloads on AMD GPUs can quickly consume 100GB+ of disk space. The PyTorch ROCm stack alone is ~18GB, and each new environment duplicates this.

The Problem

Creating environments independently:

# BAD: Each env duplicates the full PyTorch ROCm stack (~18GB each)
conda create -n project1 python=3.12

	# Fix Electron App Sandbox Crashes on Linux

	Electron apps on Linux often fail to launch with errors like:
	- `signal=TRAP`
	- Sandbox-related crashes
	- Apps that work with `--no-sandbox` but fail otherwise

	## The Problem

	Electron's sandbox requires either:
