Good morning Fedi! Do any of yall use a operating system that's not Linux, Windows, BSD or Mac on a regular basis? If so, which one?

I am this old...
Drifting off to sleep, I had a dream about #DOS game 'Links - The Challenge of Golf' (Golf month coming soon to @dosgameclub!).
'Torrey Pines - South' was the only course available in the game (I've only recently found more for dl). Never knew where it was - San Diego apparently, stay classy 
I dreamt I had stumbled across the course and been invited in, due to my #MSDOS interest.
"You love DOS? Hey, we were in Links! Come in! You can't play golf but here's the bar!"
Anyway, I'm awake now.
Uploaded a new version of KILO LISP, a LISP system with a size in the kilobyte range (22KB on DOS, 26KB on CP/M). This version contains many fixes and improvements from MICRO COMMON LISP, which is derived from it.

Threat Actors Exploit Linux SSH Servers with SVF Botnet
Cybersecurity researchers have uncovered a new attack campaign in which threat
actors are targeting Linux SSH servers with weak credentials to deploy the, SVF
botnet a Python based DDoS malware. This botnet uses Discord as its command-
and-control (C2) platform allowing attackers to manage infected servers in real
time. The SVF botnet is capable of launching Layer 7 (HTTP flood) and Layer 4
(UDP flood) DDoS attacks turning compromised servers into powerful tools for
disrupting targeted systems.

This post was inspired by the accessibility, or lack there of, of various operating systems, annoyances that people have with Windows, and the current state of Linux, which many sighted people tout as a great Windows alternative. While there are obviously some blind people who use it, overall, the experience is neither streamlined nor easy. and it can be downright frustrating. There is Mac OS, but then, there is the expense of a Mac, plus the fact that many normal periferals can't be used with it. There are Android and IOS, but these are touch-based, not built for computers, though both can be used with real keyboards. Still, such operating systems come with their own headaches.
My solution is one that cuts through all of the hurdles to a system that is fast, efficient, light on resources, and very accessible. This is DOS. I am not referring to MS-DOS, but to modern varients such as FreeDOS (just updated this year), Enhanced DR-DOS (updated a few years ago), VDOS (a version that runs directly in modern Windows systems), etc. For instance, this is FreeDOS.

This is a wonderful (and long) list of general fallacies that people may hold about the operating system, as well as statements debunking them and proving why it is still a viable choice in 2025.

For us in the blind community, there are really only two issues standing in our way. The first is a good screen reader, and the second is software synthesis. Yet even these can be overcome. While many DOS screen readers were made in the past, only one is now completely open source. That is Provox. The entire code is available for us to update to our hearts' content. (Look down the page and you will find the download link under the screen reader section.)
Of course, we could create an entirely new one, but this gives us a good place to start if we don't want to reinvent the wheel. As for hardware synthesis, it was done in the past, with Flipper. It's not the best, but it shows that it is possible. Now, with all of these updates to DOS itself, as well as faster machines with better memory, soundcards, and drivers, it should be easier to create a software synthesizer.
There are still people programming for DOS, both for everyday use and versions of the operating system itself. Why not collaborate with them? Why can't we have a text-based, keyboard-driven operating system that works for us, that isn't bloated, and that we can even help to create? Imagine a version of DOS designed with accessibility in mind. What if it came with a built-in screen reader that talked during installation, braille support, a magnifier, ocr software, various other accessibility options, and menus that were easy to navigate for those who didn't wish to use the commandline, as well as access to it for those who did? What if it were free, or at the very least, extremely cheap, and could run on almost anything, so that anyone in the world could use it, provided he had some sort of computer? This is all within reach.
How many of you would be interested in at least trying out these modern versions of DOS to see what they offer and how far we could take them into the realm of accessibility and daily use?

Do you know if it would be possible to put many different #DOS versions (#msdos 4.x-8.x, #FreeDOS 1.4, #SvarDOS ) on a single FAT16 partition, each one in its own subdir (MSDOS5, MSDOS6, FDOS14, etc.) and have a boot loader that’s loading each variant of MSDOS.SYS + IO.SYS (or others) for every DOS version?
Just because FPC community doubts validity of DOSBox (i.e https://forum.lazarus.freepascal.org/index.php/topic,71748.msg561036.html#msg561036 but not only) and rambling about everything except what I report on their GitLab ( https://gitlab.com/freepascal.org/fpc/source/-/issues/41337 )
Neu im Blog: Meine erste Begegnung mit einem MS-DOS-PC fand im Jahr 1991 bei meinem Cousin statt: Er war stolzer Besitzer eines 286ers. Ehrensache, dass ich ihn in dieser Zeit sehr oft besuchte.

I think the #ItxLlama is an interesting project.
- Shure it's not what I'm looking into but for those that want to rock an #AGP Graphics Card this is propably the #ITX #Maindoard to go with!

Trying to port Mario & Luigi (1994) by Wiering Software from Turbo #Pascal to #FreePascal trunk (i8086), ofc on #DOS: https://wieringsoftware.nl/mario
Posted on https://forum.lazarus.freepascal.org/index.php/topic,71748.html but got nowhere
I can build it on FPC, but can’t run. Removing call to ReadConfig shows gfx issues and input gets messed. I can’t find a way to debug the realmode properly
May I ask heroes from my feed for some helping hand? @foone @wyatt @root42 @nina_kali_nina
Continued thread
Ok , ima be good and not tear open the hardware to install the bus mouse tonight, so there's time for a poll:
Microsoft BUS mouse. Best DOS driver?
So, a youngster took an old Mac (before Unix based Macs), installed MS DOS plus the Microsoft C Compiler on it, then wrote a fully functional text editor for an x86 PC. And added a handmade Russian character set. Oh, also a printer driver for a dot matrix printer.
Can confirm that the PR blurb for Herb Schildt's book "If you only have one C reference book, make it this one" is justified.
What? No, I am totes neurotypical, not a nerd, obviously.

@lea I think #PowerShell is more #cursed than any other #shell becaise #Microsoft can't be assed to have any consistency and one gets commands that look like
CamelCase.command-network.option -flag --another option +includeThis +-excludeThat :user
And it's worse than #MSDOS / cmd.exe, sh tcsh & ksh combined because it mixes up #DOS / #CPM-Style, #UNIX-style and whatever the fuck the peoole.who designed the #Refistry in #Windows felt like that particular day...
- Makes me so fucking angry!
#Funfact: I needed less code than that to build my first bootable version of @OS1337 just by comparison!
~100 kitties in a café:meowpumpkin: (@lea)mfs will go "powershell is so easy and intuitive" and then i look up what the equivalent to chown in powershell is and the first result is this (📎1)
Made a new release of #OpenCrystalCaves!
https://congusbongus.itch.io/opencrystalcaves/devlog/984248/040
This release includes playable levels 1 & 3, both with unique mechanics, as well as features like sound!
The game has likely hit an inflection point, as work on laying groundwork tapers off while the pace of features and polishing pick up. Hopefully episode 1 will be playable before too long!

Well the sub title "Just because commercial unix was to expensive for him." Is not quite true. At that time the Intel 386 chip was the latest one. #ms #dos 3.2 (plus minus) was the operating system. No multi tasking/no multi user 650kB RAM. Above 650kB the driver space. (himem.sys to bypass that and so on...) The chip can do all that but the OS was so bad. Based in #minix (needed as a boot helper) he started with #linux.
And he unleashed the processor at that time.
As promised: PartUtil a limited partition editor that makes dual booting DOS and Win 9x without a boot manager easier.
Hide, unhide and make partitions active. Save and restore MBRs to files. And a few extra tricks that help with initial setup. Runs on any PC compatible and any version of DOS. Source code included.
(I've been using an earlier version of this for years on a PCjr. This is a complete rewrite that is finally worth sharing.)
A few weeks ago I wondered what it takes to turn a small LISP-1 into a LISP-2. Turns out it takes just a few hours to get most things right, then some days to iron out a few subtleties, and then a couple of weeks to polish it into a piece of art.
MICRO COMMON LISP is a tiny, purely symbolic, microscopic subset of #CommonLISP. It runs in less than 64K bytes of memory, even on #DOS (tiny model) or CP/M. Here it is:
