Advanced Programming in the #UNIX Environment
Week 01, Segment 01: Introduction
In this video lecture, we provide an introduction, discuss the purpose of the class, the syllabus, student expectations, as well as available resources.
Note: The videos in this series were mostly created in 2020. A few things have changed since then. Specifically, consult the course website for updates regarding the assignments.

#TIL that
casestatements in #unix #shell stop evaluating once they find the first match. Some shells (bash & mksh) have syntax to keep evaluating each additional statement, but they aren't all the same syntax (although mksh does seem to accept bash's;;&.25 years of shell #scripting, guys. 🤣 🤦♂️

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:

@juandesant this is built into bash as $RANDOM and $SRANDOM as well. Its been there since 1989 when it was created, but the Korn shell seems to have invented the idea in 1986.

NetBSD 9.x reaches end of support
To bid farewell to NetBSD 9.x, there are some security and stability fixes one last time. A switch to NetBSD 10 or 11 is explicitly recommended.

You won't get #dd to not have long options. It's had long options for the entirety of its existence, from about 15 years before #getopt long options were even invented.
What this does is give them the standard Unix syntax with dashes, in addition to the existing original JCL syntax.
The only supposed worse interface that this encourages is that which the dd command itself has had all along. (-:
