but for the past month I’ve kept a journal where I put an “X” next to every date where a GitHub outage has negatively impacted my ability to work. Almost every day has an X.

That’s pretty insane, especially for a big infrastructure platform like GitHub.

I haven’t had many issues, but while I regularly visit and use GitHub, it’s certainly not every day and in-depth.

It’s an encompassing shell with great data handling and native parsing and encoding/decoding.

I much prefer it over other shells or scripts and have used it for various things, in general, and related to data analysis, data transformation, and data generation.

Nushell

They’re bash/shell- and bin-dependent commands rather than Git commands. I use Nushell.
Transformed to Nushell commands:

• The 20 most-changed files in the last year:
  git log --format=format: --name-only --since="1 year ago" | lines | str trim | where (is-not-empty) | uniq --count | sort-by count --reverse | take 20
• Who Built This:
  git shortlog -sn --no-merges
git shortlog -sn --no-merges --since="6 months ago"
• Where Do Bugs Cluster:
  git log -i -E --grep="fix|bug|broken" --name-only --format='' | lines | str trim | where (is-not-empty) | uniq --count | sort-by count --reverse | take 20
• Is This Project Accelerating or Dying:
  git log --format='%ad' --date=format:'%Y-%m' | lines | str trim | where (is-not-empty) | uniq --count
• How Often Is the Team Firefighting:
  git log --oneline --since="1 year ago" | find --ignore-case --regex 'revert|hotfix|emergency|rollback'

/edit: Looks like the lines have whitespace or sth. Replaced lines --skip-empty with lines | str trim | where (is-not-empty).
