...this would need some kind of smarter scope guard...

I also can't get O_NONBLOCK to survive process exit on macOS. This is possibly because macOS is now zsh, and this RedHat bug suggests that zsh clears O_NONBLOCK:

arc may leave stdout/stderr nonblocking.

secure002 and secure004 are likely easy to take out of service, since they're pure replicas.

See PHI2090 for another report of this. Chrome hasn't changed behavior since the last update, so I'm more inclined to look at workarounds.

A point against AllowEncodedSlashes Off which I hadn't connected the dots on is that "security researchers" from HackerOne will report URLs like this as "content injection vulnerabilities" for all time:

It may be doing it that way to avoid the possibility for missed timer overflows?

I'm starting with an absolute bottom-of-the-line 3018, I've "upgraded" it with a plotter collet I made out of a pool noodle and a piece of cable gland so I'm less likely to hurt myself for now:

The digestWithNamedKey() issue above generally impacts anything using immutable caches, so it can affect CSRF too.

• This is far afield from any application I have today, but it seems plausible to operate a small-scale DIY plastic foundry (Ref) that converts plastic waste into blanks for machining or injecting into machined molds.
  • The cost to just buy premade plastic blanks doesn't seem particularly high (roughly comparable to plywood?) although I know nothing about plastic qualities.
  • Unsurprisingly, it seems like the market for recycled plastic material doesn't have a lot of DIY buyers (unit sizes are often: 1,500 pounds; per metric ton; per 40,000 pound truckload; "*Only Quantities of 10k lbs Plus").
• There are a handful of people doing extremely high-precision DIY EDM machining (Ref).

Yes. I closed down registration on this install (secure.phabricator.com) several years ago because the overwhelming majority of users who registered accounts here didn't read or follow the rules. Access to secure.phabricator.com is now invite-only.

Ah, I think it's:

(This might need to be sprite-sheeted too, but I think the sprite stuff hasn't been used in years -- since we switched pretty much everything to icon fonts -- and don't remember exactly how it works. I can look into it and do the actual bin/uh-generate-a-sprite-sheet or whatever in a followup.)

Thanks!
