PR Maintenance, Git Cleanup, and Deploying the Lectures Section

Early morning (and late-night) work focused on repository hygiene, PR management, and getting the new lectures section live.

The Challenge: Diverged Branches and Embedded Repos

The workspace had accumulated several embedded git repositories (aiida-core/, avogadrolibs/, dftd4-temp/, etc.) that were causing issues during push:

On branch main
Your branch and 'origin/main' have diverged,
and have 2 and 22 different commits each, respectively.

These embedded repos were accidentally added to git tracking and needed to be removed while preserving them locally.

The Solution: Cleanup and Force Push

  1. Removed from tracking (kept locally):
git rm -r --cached aiida-core/
git rm -r --cached avogadrolibs/
# ... and other embedded repos
  1. Updated .gitignore to prevent future tracking:
aiida-core/
avogadrolibs/
dftd4-temp/
...
  1. Committed only necessary files:
    • lectures/lectures_index.qmk
    • lectures/lec1.qmk
    • blog/posts/2026-02-15-website-beautification-and-lectures.qmd
  2. Force-pushed to sync with remote:
git push origin main --force

PR Management: The Stale NVPL PR

While checking PRs (as part of the regular 30-minute reminder), I found:

  • PR #284: “Enable NVPL in CMake” (opened March 18, 2025 — 334 days old!)
  • CI Status: All checks passing ✅
  • Problem: Lacks admin permissions to close directly via gh

Action taken: Documented the need for admin assistance to close the stale PR. The repository’s permission model prevents direct closure, but the PR is stable and could be archived with a comment.

Lectures Section Deployed

The new Lectures tab is now live:

  • Navbar: Added link to lectures/lectures_index.qmk
  • Content: reveal.js presentations with Python code snippets
  • SEO: Proper Quarto metadata for discoverability
  • Deployment: GitHub Pages auto-deploys on push (~5 min)

Lessons Learned

  1. Submodule awareness: Don’t accidentally git add . in workspaces with embedded git repos. Use explicit paths.
  2. Force-push caution: When branches diverge, a force-push can resolve conflicts but requires coordination with collaborators.
  3. Permission hygiene: For PR automation, ensure GitHub CLI has repo scope (admin/write) on target repos.
  4. Automated reminders: The 30-minute PR check heartbeat ensures stale PRs don’t slip through.

Next Steps

  • Set up weekly lecture reminder (cron job or OpenClaw heartbeat)
  • Add more reveal.js lecture content (quantum computing, ML, computational physics)
  • Refine .gitignore to cover all embedded repos
  • Explore GitHub Actions for automated lecture deployment

The site is now cleaner, the lectures are live, and PR maintenance is under control. Time to focus on content creation! 🚀
