The tenacity of Doom players to make the game run on everything is amazing
It's not just about being DOOM players. It's a long running joke in the programming and engineering world. Wether it's a fridge, a toaster, a decommissioned 1970s super computer... can it run DOOM?
It's the computing world's version of a shitpost.
The main reasons why it's Doom specifically are also because:
-
The game is open-source: https://github.com/id-Software/DOOM/pulls?q=is%3Aopen+is%3Apr This makes it much more doable to port it to other platforms (and to strip out anything not absolutely required to get the first level to run when you run into technological limitations) than when you have to rely on unofficial modding tools.
-
It's nearly 30 years old and designed for computers with only a few megabytes of memory and for processors of well under 100MHz, which are specs which the majority of modern systems have, even embedded systems. It also renders fully on the CPU and doesn't require specific hardware like a GPU or a specific graphics chip.
-
Being a first person shooter with 3D-ish visuals it looks a lot more impressive than if you show off a simple game like Pong orTetris or something like that. It has the right balance between performance requirements and impressiveness, and it's also a game that was very popular in its time and it's instantly recognisable to a lot of people.

This is so stupid. I love it!
lol this reminds me of psDoom

Can we run Doom on printers?
Ofcourse
I'm ignorant, but what does this means? I mean, what's the difference running it "in the kernel" and running it normally on windows?
Windows (and most other operating systems) have a "user land" and a "kernel space".
"user land" is where all your applications run. A "user land" application can only see other applications and files owned by the same user. Eventually, a user land app will want to do "something". This can be something like read a file from disk, make a network connection, draw a picture on the screen. To accomplish this, the user space app need to "talk" to the kernel.
If user space apps were instruments being played in an orchestra, the kernel would be the conductor. The kernel is responsible for making sure the user land apps can only see their respective users files/apps/etc.
The kernel "can see and do everything", it reports to no one. It has complete access to all the applications and every file. Your device drivers for your printer, video card, ect all run in "kernel space".
Basically, the OPs link: they've ported Doom to run effectively like a device driver. This means that if doom crashes, your PC will blue screen.
This has no practical purpose, other than saying "yeah, we did it" :)
Print drivers in Windows have actually been in userspace for a while now. That’s why the cheap drivers that come with your $40 Inkjet from Walmart don’t cause bluescreens anymore.
Thank you both for your reply! Now I got it!
And that is the sheer absurdity: doom as a device driver. Sheer and unabashedly luncacy, because why the fuck not. I approve
It means that all the code is running in privileged kernel mode instead of user mode. Kernel mode is usually reserved for the operating system and device drivers only. If code running in kernel mode has an unhandled exception or error, the entire system will crash. This creates the BSOD or “blue screen of death” on Windows.
User mode is less privileged and where all your typical applications run. If something crashes in user mode, it only crashes that process, not the whole system.
It’s a crazy thing that they did. Very impressive technically, but not really useful.
I really want to see someone get Doom running in Emacs. I've tried to figure out if anyone has but of course what actually comes up is "Doom Emacs" which is a specifically customized version of it.
Its not emacs, but i think mezzano has doom running on it.
I am pretty sure that your goal qualifies as evil chaotic. Not because the game is evil, but because the platform is Emacs. I mean, everyone knows it's Vim.
Emacs literally calls it's Vim emulation Evil mode :)
In all seriousness though, I say Emacs mostly because being a Lisp machine, it's turing-complete. There's web browsers in Emacs, PDF readers, email clients, EXWM is literally Emacs as your window manager.
Also what I've realized recently is... Vim keybindings aren't even that great beyond being modal, anyways. Some dude made an Emacs plugin called Xah-Fly-Keys that makes it modal, but works off of what commands are used often rather than how Vim does stuff like making the "go to the end of the line" key $ for some reason. With Emacs being something you can sort of just live in, I can bring my workflow into it rather than praying that what I'm using has vim key support.(Fuck I'm participating in the editor wars, fuck my life)
