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

Docker Layering For PyTorch ROCm In Action

When building multiple AI/ML Docker images that all need PyTorch with ROCm (AMD GPU) support, naive approaches can waste tens of gigabytes of disk space. This guide shows how Docker's layer sharing works and how to verify your images are efficiently layered.

The Problem: Misleading Image Sizes

Running docker images shows seemingly massive duplication:

Preventing ComfyUI Custom Nodes from Overwriting PyTorch ROCm

The Problem

When using ComfyUI with an AMD GPU and PyTorch ROCm, installing custom nodes via ComfyUI-Manager (or manually via pip) can silently replace your ROCm-enabled PyTorch with the default CUDA version.

This happens because:

Custom nodes specify torch as a dependency in their requirements.txt
pip resolves this to the default PyPI torch package (CUDA version)
Your ROCm torch gets overwritten without warning

	# 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:
