Yeah turns out writing a shell is a whole lot more work than I thought

Fuck man, why can't I just find a cool project that is actually doable in a normal lifetime

I've just learned that some unicode codepoints (like 𘀀) are wider than 1 cell in a normal monospace terminal

Yay, i hecking love unicode
(i want to die)

Working on some linux shell/terminal stuff and chatgpt really is both a saint and a curse

It's super helpful but like half the stuff it tells me is just flat out wrong

Never forget to double check guys!

I don't care, skeuomorphism like iOS 6 or window 7 aero was the peak of design and you can't convince me otherwise

Reactive state tracking in JS frontend frameworks is just ridiculous

This is a language that encourages you to create huge trees of objects but from what I can tell most frameworks have real trouble detecting any change more complex than a direct assignment

Am I missing something? I have a reactive list of objects of which fields get updated. I have no idea how to make that trigger UI updates.... This is just torture

The early 2010's were the best period in time ever and it has just been downhill from there

Don't you love it when the docs say that RTCDataChannel is a transferable object and then you try to send it to a service worker and your browser tells you it isn't transferable

I hecking looove web development 😇🔫

Doing some JavaScript right now and holy moly is this one spaghetti ass language

Promises referencing closures referencing local variables referencing message handlers referencing resolve callbacks referencing ... 😵‍💫

TIL json can't encode NaN or +/-inf. wtf!?...

Just had a thought: Instead of LLVM modeling and optimizing an IR and then backends having to optimize again for actual machine code lowering, wouldn't it be possible to unite both under one unified system?

If you model everything as one huge and complex state machine with a bunch of predefined "micro ops", couldn't you write an optimizer which lowers to the mathmatical presentation of the target platform's instructions?

I.e. the actual identities of the instructions don't matter. What matters is that the input ir is `(x + 3) & 0xff` and the optimizer tries to fit a sequence of instructions to that so that it "solves the system". It doesn't know x86 `andb`; it knows that `andb` takes an input, maybe truncates it, does a bitwise or, and stores the output into a reg

That way you wouldn't have to write complex target dependent backends. Just declare the sequence of actiosn each instruction does and llvm would automatically be able to produce very high quality machine code

I think there's a phd worth of research here but helllll no I'm not touching compilers again lol

Advice: Don't use react

Isn't it weird how you have never tasted some food but you know exactly how it tastes?

Somebody brought up shrimp cocktail. I've never had it and I've barely ever had shrimp. But in my mind I know the *exact* taste it has

How is FBX the main format of blender when it is so damn bad

For the last 10 minutes I have tried exporting a model as fbx so that it has the same scale and coordinate system as in blender. That's literally the only job a model file format has to do

I still haven't managed to do it. How can a model format be this frustrantingly bad???

I just realized that charities being scammy and pocketing most of the money for themselves isn't actually a shocking thing

If you're a scammer, convincing people to give you their money by parading people in need around is like the easiest thing ever

Of course all charities are scams, that's literally the easiest and most legal way to scam people!

I hate zoomers so much

Cars 1 was NOT released 19 years ago. No, it just wasn't. Fuck you, it wasnt. I dont care about your facts. It's all fake. You're litearlly just lying. No it cannot have come out 19 years ago. It just couldn't have, thats way to long ago. You're just weird. Calenders are just wrong

Kernel coming along slowly but surely. I can now fetch the memory map and use normal Rust printlns to the vga text mode!

Next up is physical memory allocation and page maps

Yay, my bootloader/kernel now properly set's up long mode and successfully jumps to compiled 64-bit Rust code!

I have a revolutionary plan for avoiding hitching in my game engine due to frequent mallocs:

I'm just gonna preallocate a few gigs and disable purging, never giving the memory back to the system xD

Fuck you system! I will forever stay inside my process, you're syscalls can't screw my frame times now!

Working on an OS again has made my *really* appreciate ChatGPT

I've always thought that it's a useful tool if you can use it, but most of the time I couldn't. Low level engine work or whatever where the hardest thing is knowing what you want to do doesn't benefit from an LLM at all

But for os dev? It's honestly insane. Not that chatgpt is always right (it's mostly wrong) but the *ideas* it gives you to try other stuff and check other stuff. Those are invaluable. A dozen times it has saved my ass over the last 2 days when I was stuck

I think a big part is that when you can converse with someone who comes up with new ideas it keeps your motivation up. I remember doing osdev 5 years ago and I just quit after 2 weeks because I was stuck and I didn't know what to do

I've just wasted 3 hours on this shit

Apparently when you use -device loader in qemu to load raw code into your vm and start executing it, qemu thinks that - actually - you didn't really want to execute from 0x00007c00. What you *really* wanted is to execute random fucking gibberish at 0xffff07c00

Yes qemu, that's *exactly* what I wanted!

I hate cpp to rust bindings

All my homies hate cpp to rust bindings

(I totally didn't spend 2 weeks on this shit and it still doesn't work I want to die)

My god why are all parser combinator libraries in Rust so bad??

Is it too much to ask for to parse a normal ass programming language with error recovery???? That's like 99.99% of what people need a parsing library for and somehow error recovery is always some weird after thought bandaged on after the fact

For fucks sake, I'm finally getting over the urge to reinvent the wheel all the time, but now all the libraries suck ass so I have to. Arrghh!

@kiki

Nothing like spending 2 days solving a problem that could have been solved by 15 minutes of manual work

Hey, at least it's automated now...

I just had the most confusing error ever where clang ast randomly replaced classes with just int in type signatures

...wat? I guess the class only has one int field so maybe there's a cpp rule that requires replacing classes with their only field or something?

But when I add other fields it doesn't change. Even if the class has no int fields, it's still replaced by int in the ast

....

Yeah turns out I had the definitions in the wrong order and clang just uses int for unknown types instead of... you know maybe raising a fucking error

Thanks clang...

I love waiting 30 minutes for phsyx to finally fucking be done compiling my god can you just speed uuuuuup
