This reads like Claude wrote it (more than ChatGPT.) Interesting data but I am unsure how actionable it is. Are they suggesting, for example, that specific commit messages get scanner more closely? Why is CAN more severe than Intel? (It does worry me. I feel like bugs, of any sort, in car systems are terrifying.)
I'm not sure why this isn't included in the blog, but I was curious about the ratio between bugs and commits. Presented here are my calculations in order of total number of bugs:<p>Intel : 11.86%<p>[1] Independent : 2.27%<p>Red Hat : 9.74%<p>Linaro : 12.73%<p>Google : 12.78%<p>AMD : 9.70%<p>The above is based on the bug count table in the article.<p>[1] I combined the total bug count for independent and kernel.org because they are combined for the total contributions here, <a href="https://github.com/quguanni/kernel-archaeology/blob/main/scripts/corporate_contributions.py#L69" rel="nofollow">https://github.com/quguanni/kernel-archaeology/blob/main/scr...</a><p>This suggests that corporations are introducing significantly more bugs than independent developers. However, I have not done statistical testing on this nor have I recreated the numbers. If I had to speculate, I would assume that the analysis from the author was partly vibe-coded or they purposely left this analysis out due to fear of retaliation. Extending my speculation would also include that corporations are purposely introducing bugs out of malice such that there are backdoors available for them. The author mentions that there is no "corporate takeover" but perhaps there are more interesting conclusions to be found.
Not happy with the lack of statistical testing, some of the smaller differences in % could probably be coincidence
These smell like the kind of metrics that cause someone to feel informed and then to miss the forest for the trees. The kind of data for a "data driven" decision maker who will just invent a narrative to explain the numbers, and then do what they wanted to do all along.<p>The map is not the territory.

The LLM-tone doesn’t help:<p><i>117 people meet this criteria. And the impact is dramatic:</i><p>It’s strange to me to think of “bugfixes” in terms of a commodity. Different problem spaces between subsystems and thus different types of (and surfaces for) bugs; different contributor mixes; different number of eyes on them; different potential impacts…<p>> <i>CAN bus drivers top the list [of bug lifetime by subsystem]. These are used in automotive and industrial systems. Critical infrastructure with few maintainers watching.</i><p>…or maybe higher-quality initial submissions, with most of the easy bugs already wrung out of them, so only subtle bugs remain (thus fewer to fix).<p>Or adequately vigilant maintainers but low diversity of systems running that code, thus fewer users/situations where the bugs manifest, so they go unreported. Or poorer telemetry so an ordinary rate of latent bugs but they go undetected.<p>Could be any, probably a little of all, can’t really tell from the analysis; and each cause would suggest a different response to improve quality.
Bugs Georg, who is an outlier and should be excluded from the analysis.
