I originally used Emacs because I was a lisper and having your whole programming environment in an extremely powerful Lisp VM is pretty fucking comfy but man is it bloated.
After watching a few youtube videos on vim (no bully) I decided to make the switch to vim+tmux and it's fucking great. It's way closer to the Unix way and really pushes you towards learning your terminal and system in general (I recommend zsh if you're lazy btw).
Here's one of those videos btw: https://www.youtube.com/watch?v=wlR5gYd6um0
I recommend watching a few before diving into it, just so you know at least the basic idea behind vim. It's really quite simple and much more suited to humans than Emacs and many other bloated IDE's.

I use a plugin that allows me to run a command on another tmux window with just a press of a sequence or a hotkey.
When I start working on a project, I press a sequence, I input the command I want to run and then press enter. It runs it and saves it. Then, all I have to do is press another sequence/hotkey and it'll automatically run that command.
This allows me to use just one plugin for pretty much any project I want. It could be a simple fizzbuzz in Forth, it could be some C or it could even be writing code for the kernel and compiling it, and all of that with just one plugin.
Not only that, but this plugin also lets me seamlessly transition between Vim and Tmux windows. This is basically the only plugin I really need, the rest I rarely use.
Getting shit initially setup (vim, tmux and zsh) is really the hardest part, so feel free to mish and mash configs you see online, that's what I did. All my configs are based on other people's configs.

Not sure, never used Linux on a vm.
Learning Linux, vim, tmux and zsh/bash all at the same time is probably way too much anyways tbh. I'd recommend you dualboot Linux and just use Emacs to start off with (it's easier for beginners) or, if you're really set on being a gaymerfag forever and are too scared to dualboot, a vm running Linux (the lag might be too much tho).
I'd highly recommend running Linux only, no dualbooting or VM crap, just so you force yourself to do everything in it and don't run away when it gets too hard. That's how I and most people really got started with it.
If all you're using Windows for is gaymes then Linux will probably be a good way to great out of it (although you can certainly do some light gaming in Linux now a days), it was for me and while it wasn't easy, I'm very glad I did it. I'd probably be a /vg/ soyboy by now if I hadn't done it tbqfh.

I never considered this but you could actually just plug your monitor into discrete GPU and mobo at the same time, and use the monitor buttons to switch between inputs.
If you're interested I'd say go for it. Be warned though, you'll need to pass some kernel params in your bootloader to prevent PCI initialization until the windows guest takes hold.

I'd honestly recommend you just code for formats like farbfeld, use the framebuffer on Linux (surprisingly easy to access) or use an API that provides something similar.
I might do some basic VGA fb graphics if I get to making a x86_64 Forth system. I remember the tty framebuffer in x86 that I used for my Lisp OS was extremely fucking comfy.

Yeah, it'd be a pretty nice upgrade, but I doubt I could find a decently priced one close to me.

Oh, looks like you're talking about an iMac G3.
I've never actually seen one of those irl, but I'd love to play with it and maybe extend the bootloader into a reasonable Forth system? Who knows. (No idea if that's even possible given the limitations of the bootloader)
Have a rare Chuck because your post amused me.

Yeah, I'm doing the same kek.
You should get a group together to do a few demos or something. IRC, discord or whatever meme you pick should do fine (I recommend discord tho tbh).
Doing crackmes or reverse engineering abandonware would be nice too.
I certainly have more than enough money for that mid range cheapo setup (no more than 500 shekels for the tower) but I really don't want to be buying that kind of stuff when I'm being a lazy NEET.

I actually already have a pretty big Forth Discord server. I could transform it into a Forth/Demo/RE server and give you admin if you wanted to.

I actually don't use Discord a lot, so I'm not sure.
We could have a Forth and a Demo channel, if that's what you mean by "subchat". Sounds pretty good to me.

I've been considering switching to IRC, but IRC channels die so fucking quickly it's hard to believe. The good thing about Discord is that it encourages more casual posting from people that would generally only visit the channel for a few hours.

I'd personally much prefer to use IRC, but we all know IRC channels never last long. I actually wrote some gforth code for a simple IRC bot expecting to move my Discord server to freenode.
I'm more than willing to have an IRC bridge for those that want to use it, but the incentive to lurk and irregularly post that Discord gives is invaluable for a small group like this.

What fucking language is that supposed to be? A particularly bad version of Basic?
No idea what it's trying to do tbh.
I remember that neat piece of quake code is extremely hard to understand. Even when you have someone break it down into steps, it still requires you to understand IEEE floating point representation and some pretty neat math tricks.
those last lines which he calls 1st and 2nd iterations are actually just a way of improving the approximation using Newton's method, really neat shit
▶ No.887790>>887792

yeah the magic number is supposed to improve precision
i have no fucking idea how though
also yeah, its qbasic, it generates and raycasts a voxel height map in realtime

>also yeah, its qbasic, it generates and raycasts a voxel height map in realtime
There are some pieces of code too ugly for even this world, anon.
Bury that shit and forget about it, wew.
And yeah the magic is used to do the initial approximation and that 1st iteration simply refines it pass a point where it's good enough.
Just to be clear, this is an amazing hack not just because of the extremely clever nature of it, but also because this is what allowed Quake to have a proper 3d engine before GPU's were really a thing.
This inverse square root function was at the heart of the raycasting engine that ran on the CPU. (I think it was mainly used to calculate the angle of the light/ray after reflection/casting)

inverse square root is used for normalizing vectors
basically it transforms m*cos(x), m*sin(x) to cos(x), sin(x)
