My friend E. Prybylski talks about why there must be #legal #due #process for *every single person.* It is #inhumane to #deport and #imprison anyone without due process. We are on our way to becoming an inhumane nation, and we must stop it now. https://open.substack.com/pub/ehprybylski/p/a-day-of-protest

NaPoWriMo 2025 Day 17 https://quiltr.com/?p=25072 sitting outside while • The wind scuffs up my coffee • And I shiver … #blackcat #cats #dogs #dothework #haiku #NaPoWriMo #poetry #process #quote #spring

I finally eliminated the need for a dedicated #thread controlling the pam helper #process in #swad.

The building block that was still missing from #poser was a way to await some async I/O task performed on the main thread from a worker thread. So I added a class to allow exactly that. The naive implementation just signals the main thread to carry out the requested task and then waits on a #semaphore for completion, which of course blocks the worker thread.

Turns out we can actually do better, reaching similar functionality like e.g. #async / #await in C#: Release the worker thread to do other jobs while waiting. The key to this is user context switching support like offered by #POSIX-1.2001 #getcontext and friends. Unfortunately it was deprecated in POSIX-1.2008 without an obvious replacement (the docs basically say "use threads", which doesn't work for my scenario), but still lots of systems provide it, e.g. #FreeBSD, #NetBSD, #Linux (with #glibc) ...

The posercore lib now offers both implementations, prefering to use user context switching if available. It comes at a price: Every thread job now needs its private stack space (I allocated 64kiB there for now), and of course the switching takes some time as well, but that's very likely better than leaving a task idle waiting. And there's a restriction, resuming must still happen on the same thread that called the "await", so if this thread is currently busy, we have to wait a little bit longer. I still think it's a very nice solution.

In any case, the code for the PAM credential checker module looks much cleaner now (the await "magic" happens on line 174):

On a #coding mission to improve my #poser lib .

In the current implementation of #swad, I don't really like that I need an extra thread, just to control a child #process. A first piece to add to poser is generic "child process support", which I'm testing right now. I realized I could reuse my #Connection class, which was built for #sockets, but works just as well with #pipes

TODO now is mostly testing. See screenshots for some mimimal testing code and its output ... would you like this kind of interface?

Weaknesses of AI image generation
The biggest flaw in AI image generation software is that it completely ignores the basics and just starts coloring the picture itself.

"Sometimes we feel like a quiet stream, flowing gently within.
Then suddenly, the current quickens, pulling us into a whirlpool with no end in sight.
But in time, we always return to that stream.
With patience, and trust in the current inside us, carried by the streams around us."
