97% C, No Apologies
Your language breakdown is 97% C. In 2025. Not retro-chic — just retro. The 0% Rust is doing a lot of heavy lifting for a kernel maintainer who keeps telling everyone else to write Rust.
83% Graveyard
staleRepoRatio: 0.83. You have 84 public repos and roughly 70 of them haven't been touched in over 2 years. Your GitHub profile is less a portfolio and more an archaeological dig site.
following: 0
You follow zero people on GitHub. Zero. The man who decides what goes into the Linux stable kernel follows nobody. Absolute monarch energy. Or just forgot the password to the settings page.
19 PRs/Year for the Stable Maintainer
Only 19 PRs submitted this year — which makes sense when your actual workflow is a 30-year-old email patch queue. GitHub is basically a mirror you maintain out of obligation.
No CI on the Linux Kernel Repo
HAS_CI=no on the linux repo. The most important software repository in existence, maintained by you, and the CI flag is red. Yes, the kernel has its own infra — but the irony is exquisite.

gregkh /
linux
Linux kernel stable tree mirror: 4.7GB of production-critical systems code with decades of governance, comprehensive documentation spanning multiple subsystems (memory, scheduler, networking, filesystems, security), and continuous development across all commits.
gregkh /
usbutils
Production USB utilities library (lsusb et al.) with 17-year history, 440 stars, typed C code, comprehensive test suite, CI/CD, and structured multi-file architecture serving Linux ecosystem.
gregkh /
kernel-history
Long-running Linux kernel statistics analysis project by Greg Kroah-Hartman with ~15yr lifespan, multiple analysis scripts, and structured data workflows. Well-established portfolio project with active maintenance through 2026.
gregkh /
gregkh-linux
Personal Linux kernel development framework with shell/Perl scripts for managing stable releases, patch queues, and build workflows. No README; untyped scripting languages; 104 stars suggest niche adoption among kernel maintainers.

▸ How the pipeline works
- 01Scrape.Pull every non-fork repo pushed in the last 90 days, plus your contribution calendar, followers, and language byte counts — straight from GitHub's REST & GraphQL APIs.
- 02Triage.A small model reads every repo's file tree + README and picks the 20 files per repo that actually reveal how you code.
- 03Grade each repo. All repos run in parallel through a fast scoring model that reads the picked files and rates each one independently on Impact, Quality, and Depth — with evidence citations.
- 04Aggregate. A larger reasoning model combines the per-repo scores with server-computed stats (heatmap, commit cadence, language entropy, follower count) to produce the 6-dimension profile score + roasts.
- 05Correct.Deterministic server-side checks enforce anchor-scale floors (e.g. a profile with 2,000+ public commits can't score 30 Consistency) and recompute the final verdict.
~90 seconds per profile, ~$0.25 in compute. Total of ~240 files read across your top-12 repos. One rating per GitHub account per day.
▸ Data sources & caveats
- Heatmap & commit totals: GitHub GraphQL
contributionsCollection— covers the last 365 days, includes private repos when the user has opted in (default). - Language %: byte totals across the top 30 owned non-fork repos.
- Curve: a small upward nudge centered on raw score ≈ 70, capping at 100. Prevents specialists from being unfairly penalised for narrow breadth.
- Anchor corrections: when server-measured signals (e.g. privateWorkLikely, multiRepoVolume, follower count) mandate a minimum category score, the aggregation step enforces it. These are signal-conditional, not identity-based floors.
