> DDD is still maintained?
Absolutely. I wrote about its features here https://begriffs.com/posts/2022-07-17-debugging-gdb-ddd.html
Since the article was written, the maintainers fixed the issues I pointed out. No need for many of those workarounds now. Versions 3.4.0 and 3.4.1 are substantial.

I see CMSIS definitions for the RP2040 at https://github.com/raspberrypi/CMSIS-RP2xxx-DFP but none for RP2350. Maybe they'll eventually appear in that repo, given its name is RP2xxx? I thought vendors are legally obligated to provide CMSIS definitions when they license an ARM core.

I have a hard-copy of this book, and it seems like the PDF isn't the final version, judging by the hand drawn illustrations at least.
The book does dive into some old and arcane object file formats, but that's interesting in its own way. Nice to get a comparison of how different systems did things.
After reading that book and other sources, I examined how people typically create libraries in the UNIX/Linux world. Some of the common practices seem to be lacking, so I wrote an article about how they might be improved: https://begriffs.com/posts/2021-07-04-shared-libraries.html
Edit: That covers the dynamic linking side of things at least.

Interesting, maybe it depends on the reader. I tried a channel just now in newsboat and it wasn't smart enough to find the feed, even though I see the page contains

Oh yeah, gotta love the secret feed link.

I still follow many RSS feeds (about 250). Sometimes it's hard to find the feed on a site, because the feeds aren't always advertised and their URLs can be tricky. Based on the URLs I've seen, I created a simple script to check if a site has a feed:

I've been meaning to give Motif a try for cross-platform C GUIs. Can anyone share their perspective with that, and compare with IUP?

I put together a list of the best linear algebra books, classified by type. Proskuryakov's practice book is one of them. Here's the full list:

As I got more into C programming, I started looking for data structure libraries. Found a few [0]. Also evaluated sc, but it had too much pre-processor magic for my taste. It also bundles random "stuff" like a URI parser, a thread abstraction, etc.
Eventually I rolled my own [1] more focused library. It's basic and portable.

Good idea to just abort it. :)
However, I tried your suggestion from another terminal, and gdb appears to shield the program somehow. What ended up working is running "signal SIGABRT" from within gdb.
One thing that's still lacking is gcore's ability to take a snapshot of the core without killing the program. "Unlike after a crash, after gcore finishes its job the program remains running without any change." https://www.man7.org/linux/man-pages/man1/gcore.1.html

The combinations came from what I observed in the big list of blogs I follow. The script works pretty well for most sites.
