Git Commit Message AI
# -----------------------------------------------------------------------------
# AI-powered Git Commit Function
# Copy paste this gist into your ~/.bashrc or ~/.zshrc to gain the `gcm` command. It:
# 1) gets the current staged changed diff
# 2) sends them to an LLM to write the git commit message
# 3) allows you to easily accept, edit, regenerate, cancel
# But - just read and edit the code however you like
# the `llm` CLI util is awesome, can get it here: https://llm.datasette.io/en/stable/

How to use FFMPEG to convert HDR video to SDR (standard dynamic range) while (mostly) retaining the same depth and intensity of colors, without washed-out colors, as the original HDR10+ video.
ffmpeg -i video-input.mp4 -vf zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p -c:v libx265 -crf 22 -preset medium -tune fastdecode video-output.mp4

Orgs and Teams Best Practices

Organization archetypes

The intention of this document is to provide some guidance and suggestions to customers who are wondering how they should structure organizations and teams in their GitHub Enterprise environment. The idea isn't to give hard and fast rules on which approach is better than the other, but to give examples of when one approach might be preferable to another depending on the use case.

1. A single organization with direct organization membership for repository access (not teams)

Initialising Empty Structs in Rust

In C/C++, you can initialise a struct without giving values for any of the fields:

struct Point {
  float x;
  float y;
  float z;
};
