Advanced Programming in the #UNIX Environment
The objective of this class is to learn and understand the interfaces, libraries and concepts we cover as well as to actually write code. This requires struggling with code, to work your way through your problems rather than copy together AI generated snippets and pasting errors into a prompt.
Below are my updated slides on the use of AI in this class, and this is our policy:

kids these days don't know the joy of #UUCP bang path routing of every email. Half the awe of every email was to see the journey taken.

⚪️ Running Arch Linux on Low-Memory Computers: A Lightweight Setup Guide
🗨️ In this article, we will modify the Arch Linux 2024.06 distribution so that it can be used on computers with limited RAM. Along the way, we will explore the structure of the ISO 9660 filesystem and learn how to use standard tools to solve semi-hacking tasks.

OTD 1941: The birth of Dennis Ritchie, co-creator of #UNIX.
I had the great honor and privilege of working directly with Dennis during my summer at Bell Labs.

I now believe Jim Blinn when he was telling me about his impression of UNIX V6 while at NYIT: “I was somewhat unimpressed with Unix at the time because it was so flakey”. But, I'm working with a version from about a year earlier.
After I moved /usr/source to another disk and setup a mount, I've been encountering so many "fun" issues due to a buggy RK05 driver and tools that don't fully support mounts. For example, when you're at the top-level of a mount, `chdir ..` doesn't move you up, so you can't escape a mount unless you use a rooted path. I believe this is the cause of a stack exhaustion in `ls`, when it's looking for a file on another mount.
I'm surprised no one crashed the system yesterday, since that was just after I setup the mount.

A newish bugfix release for Cozenage Scheme interpreter. The next release, in a week or so, will have support for importing user-written and third-party Scheme library loading. Probably worth waiting for that, but in the meantime...
Also, Cozenage is now available from the Guru repository, if you use Gentoo Linux. Just:
# emerge -av dev-scheme/cozenage
https://github.com/DarrenKirby/cozenage/releases/tag/v0.19.1

Or 2015, or 2025. You haven't actually looked at the history; despite my giving the years explicitly. So it's not saying that at all.
Laurent, you're arguing based upon not actually knowing the history, and if anyone is thinking that the #Unix landscape is the same as it was in the past, it is surely you for arguing that the proper thing is for things to remain as they were in 1974.
I however know that the #Unix landscape changes, in this very way.

I don't know why I need to be dragged out of the 1970s... [1]
But I think I'm in agreement with @ska in that modifying dd's interface - which is at least 53 years old at this point - is the wrong approach. A new program, even if it takes exactly the same functional arguments and options, but formatted with the modern (?) style, seems more apropos to me.
You could even call it `ndd` for "new dd" or something, if you want to preserve a link to the old name. A new program would also allow you to drop the old interface entirely, likely simplifying the code.
But the most important factor in deciding which way this work should be done would be, of course, "Who's doing the work?", and since that's not me, my opinion counts for little.
[1] Am I particularly crotchety? I was *born* in the '70s...

⚪️ Linux Kernel Fuzzing: Setting Up Syzkaller to Find Security Bugs
🗨️ In this article, we’ll get some hands-on practice fuzzing the kernel. But first, we’ll briefly cover the history and theory of fuzzing and discuss how our target works. We’ll then configure and build the Linux kernel, set up Syzkaller, and start hunting for bugs.

Citizen Astronomy (CAst)
by ÖgetayKayali
https://github.com/OgetayKayali/citizen-astronomyEvery clear night, amateur telescopes around the world capture photons that professional observatories never will -- the right patch of sky, at the right moment, with enough patience to notice something change. Citizen Astronomy turns those images into science.
CAst is a desktop application (Windows installer primary; unsigned macOS .app zip available for alpha testers) that takes folders of FITS and XISF images and gives you the tools to measure variable stars, discover moving asteroids, build Hertzsprung-Russell diagrams, and explore the sky -- all from one guided interface, no command-line scripting required.
Please read more details in ALT-Texts of images. These images are just a few examples of the sophisticated use-cases of this software!
Another nice example:
