@charliermarsh glibc upgrades unlock use of new symbols, which may provide perf wins. Since glibc is provided by the system, any optimizations in existing functions will be realized automatically, even if targeting an old version.

@benchodroff Gotta love how the page margins and font size are increased to make this look larger. Not defending the overall size, just observing the political theater.

I’m over at https://t.co/NOGUT5SoPw now. Unsure how much more I’ll be posting here since people I follow keep leaving for bluer skies.

[indygreg @indygreg]

@MikeHommey Yeah. The feature has been there for years. But you have to bring your own code to support it. I don’t even think GitHub supports it. I imagine one could shoehorn the push certs into the repo store and have a self-verifiable repo. Like hg’s pushlog but with crypto.

[indygreg @indygreg]

GitHub finally has a solution for the “PGP key rotated/expired causing commit signatures to stop verifying” problem.

GitHub now has a “PGP key revoked and commits still verify” problem.

Feels like a net win.

@_moonstorms This is one of the original reasons for the Electoral College. See Federalist Papers No. 68.

The first RCV run out of SF seems to confirm what I was seeing tons of screenshots of: Lurie sandwiched between Breed and Farrell in ranking.

Lower of Breed or Farrell is eliminated, transferring votes to Lurie, who wins. Breed and Farrell effectively cancel each other out.

I’m on a high speed train in China and the train app allows me to order takeout food from a restaurant in an upcoming station. Food will be delivered to the train and even to my seat I think. Does any other rail service in the world do this?

I wrote a new blog post about my work on mutexes, and it's a great conversation starter for any engineer. https://t.co/Ke2AWszbqA

Good grief that looks like a lot of potentially remotely exploitable DoS bugs in today’s coordinated CPython release.

[indygreg @indygreg]

@mitsuhiko Yeah. I’m tempted to do that or just rip out the AFCI breaker for a regular one. What gets me is this worked fine for years. And the first thing I did was replace the AFCI in case it was going bad. My mobo frying itself made me think there was a reason for the AFCI trips.

[indygreg @indygreg]

After multiple years of no issues, my desktop PC starts tripping the AFCI randomly. I’ve replaced the AFCI breaker just in case. What changed? Something on the PSU? Advice online seems to be to just not use an AFCI for PCs?

[indygreg @indygreg]

Still tripped with the GPU removed.

[indygreg @indygreg]

Nope. Just tripped the AFCI again. I’m running out of components to isolate. It surely can’t be the CPU, case fans, or NVMe drives. So it must be the GPU or the enclosure somehow?

@agarwal @beyondchron I live ~1 block away. It’s gotten way worse since the sweeps began. DPW (I think) and SFPD jointly cleared people out Sunday (never saw this before). But the side streets were occupied again last night. City appears to be playing whacamole.
