🔥 Full roast
🔥 A 16-year GitHub veteran with 1121 PRs and 1782 commits to Tencent's 23k-star ncnn, three 1k+ star in-house image processing tools and 8k+ followers, this guy is the textbook OSS role model — only dow
nihui — 100.00/100 · GOD (Legendary · Hall of Fame)
TL;DR: A 16-year open-source veteran whose massive, high-impact contributions to Tencent/ncnn and his own suite of production-grade Vulkan tools make him a GitHub Hall of Famer — the only downside is he leaves roasters with nothing to work with.
| Dimension | Score | Notes |
|---|---|---|
| Account maturity | 10/10 | Registered 16.52 years, active across 18 contribution years, last activity 2 days ago. Most GitHub accounts fade out after 3 years; this one is still shipping code like it's 2009. |
| Original project quality | 17.1/18 | 76 original repos, 15,982 total stars, top repo waifu2x-ncnn-vulkan holds 3,424 stars with a 0.95 quality score (actively maintained, real-world Vulkan super-resolution tool). The only deduction is that not all 76 repos hit that same high bar. |
| Contribution quality | 28.9/27 | 1,257 merged PRs out of 1,350 total, only 21 maintainer-closed unmerged PRs (2% rejection rate), 1 recent trivial PR, 17% recent external doc-like PR ratio. This isn't PR spam — it's a steady stream of substantive, maintainer-approved work. |
| Ecosystem / maintenance impact | 20/20 | 1,121 PRs + 1,782 commits across 37 popular repos, including 950 PRs and 1,302 commits to Tencent/ncnn (23k stars), plus core contributions to PyTorch, Hugging Face Transformers, LLVM, and Ultralytics. Verified samples confirm the bulk of this work is core engineering, not docs/site/CSS touch-ups. |
| Community influence | 8/8 | 8,231 followers, only 38 following — a 216:1 follower-to-following ratio that signals real earned influence, not follow-farming or simp-style engagement. |
| Activity authenticity | 16.1/17 | 866 contributions last year, 4 distinct activity types, no templated PR flooding, no star inflation signs. No bot energy, no fake engagement, just consistent real work. |
Red flags None. There are no red flags to speak of: no spam PRs, no follow-farming, no doc-only contribution padding, no empty fork graveyards, no suspicious engagement patterns. You're welcome.
Score calibration No extra adjustment. The base score already fully prices in this account's 16 years of consistent, high-quality open-source work, so no bump or haircut was warranted.
Verdict Fully normal, no suspicious activity detected. This is the gold standard for what a GitHub open-source profile should look like — a Hall of Famer who actually earned the spot.
