TacOS: an x86_64 UNIX-like OS from scratch
TacOS is a UNIX-like kernel which is able to run DOOM, among various other smaller userspace programs. It has things like a VFS, scheduler, TempFS, devices, context switching, virtual memory management, physical page frame allocation, and a port of Doom. It runs both on real hardware (tested on my laptop) and in the Qemu emulator. ↫ TacOS GitHub page TacOS – great name – is written in C, and explicitly a hobby and toy project.

i wrote (citation needed) a PHP script thing that does a check for on demand TLS purposes and it works but like only partly? like there's records in the DB that it 404s on even though. they are very much there. so idk what's up with that but i've worked at this all day i'll leave it at this for now

@movq@www.uninformativ.de @aelaraji@aelaraji.com Yes @david@collantes.us It would be good for me, or new developers, if the documentation were agnostic. And if possible with many example cases. I’m fine-tuning the code as you inform me of bugs, trial and error. It’s a lesson to be learned for the future.
Am I the only one that’s confused by the discussions, and then the voting we had on the whole threading model? 🤔 I’m not even sure what I voted for, but I know it wasn’t the one that won haha 🤣 (which I’m still very much against for based on an intuition, experience and lots of code writing lately).

“That PHP snippet could be merged into https://twtxt.dev/exts/twt-hash.html”
Why, though? AFAIK @andros@twtxt.andros.dev’s client is on Emacs, @lyse@lyse.isobeef.org’s is on Python (and Golang, for tt2), @movq@www.uninformativ.de’s is on Python, and @prologic@twtxt.net’s is on Golang. All the client creator needs to know is in the documentation already, coding language agnostic.

Why is there a “small house” in IBM’s Code Page 437?
There’s a small house ( ⌂ ) in the middle of IBM’s infamous character set Code Page 437. “Small house”—that’s the official IBM name given to the glyph at code position 0x7F, where a control character for “Delete” (DEL) should logically exist. It’s cute, but a little strange. I wonder, how did it get there? Why did IBM represent DEL as a house, of all things? ↫ Heikki Lotvonen Don’t waste any time here, and go read the article.

Elliptical Python programming
One thing I love about Python is how it comes with its very own built-in zen.

AI problems, top to bottom:
1: Open AI nerds, believe fine tuning a language model algorithm, will eventually produce an AGI god.
2: Subpar artists and techbros who can’t code, convinced AI image bashing and vibe coding, will help convince the dumber parts of Internet, they are a real deal.
3: Parasites, using AI to scam people, because they just want passive income, selling crap, made by an automated process.
Side: Adobe&co, killing Flash/old web, pricing new artists and developers out, to face learning curves of free tools, or use AI, peddled as solution.

@prologic@twtxt.net Not sure if the confirmation helps at all. You just condition yourself to immediately press y on a daily basis.
Apart from that, aborting the removal should probably terminate the function with a non-zero exit code, something like return 1.

How big is VMS?
This question was asked during my Boot Camp presentation last fall in Boston, and over the past 35 years dozens of times people have asked, how big is VMS? That translates into “how many lines of code are in VMS”? I thought it was time to at least make a stab at pursuing some insight into the answer. I wrote some command procedures to count the number of source lines in .B32, .B64, .C, .MAR, .M64, and .S files. Not counted are blank lines and lines beginning with the standard comment characters and m … ⌘ Read more

@lyse@lyse.isobeef.org I do agree “the rules of the web”, are far too loose - at least the syntax ones. I do think backwards compatibility is necessary.
As for my website, it might be visually very similar, to how it looked since its creation, many years ago, but it is frequently improved. Features that originally used JavaScript, changed to HTML and CSS components, code simplified, optimised to withstand browser updates and new screen resolutions,… Even a good chunk of the errors on your list, were already addressed and I plan to address the rest soon.
Just find it a bit depressing, that my attempt to bring back some of the old Internet spirit, by making a hidden easteregg page page for this years April 1st, was met with people complaining about April fools day jokes and you insinuating my website sucks.
