@kernellogger Out of curiosity, I tried counting buggy commits between v5.0 and v6.0 and checking the review rates of buggy commits vs. non-buggy commits. Curiously, the rates are VERY similar; i.e. whether a commit has been reviewed or not doesn't seem to impact whether it is later fixed by another commit.

P(reviewed) = 35.37%
P(reviewed | buggy) = 35.00%
P(reviewed | not buggy) = 35.40%
P(buggy) = 7.91%
P(buggy | reviewed) = 7.83%
P(buggy | not reviewed) = 7.96%

Caveats apply...

Also makes me wonder if the Meta layoffs carried more shame with them for those affected, given the talk of *some* of them being performance related?

I've seen almost no talk about Google layoffs having performance angles, and thus easier to talk about it for those affected?

Clarification: bias since those I know from my time there, given that it was 6+ years ago, would have high tenure. I just don't have as many connections with newer hires.

Slightly odd observation: I think I have seen more posts and communication from those affected by Google layoffs, than I did from Meta.

I'm also surprised to see the high tenure of so many laid off Googlers, but I expect some bias since it's been 6+ years since I worked there.

I wrote a little thing about how I'm worried that the improved general level of discourse in the Fediverse and the degree of "Leave that sort of thing on Twitter" feeling present leaves me worried that what I found most valuable about Twitter just won't exist here: https://mjg59.dreamwidth.org/64660.html

I haven't had to by a USB Wifi adapter in a long while, and I'm disappointed that it's still a complete jungle when it comes to Linux support.

My local hardware store (Central Computer) has mostly RealTek-based devices, and not a single one of them is supported in-kernel. It's sad that this is still the case, given how much other hardware support has found its way in by now. :(
