vfork or do the VMS trick

eager yew
inner rover
#

You keep a flag and if after fork something else than exec is called you error

stuck nexus
#

That's not exactly the VMS trick

inner rover
#

What is it then?

stuck nexus
#

Fork just sets an internal flag in libc that says "fork was called" and then returns 0 to pretend the caller is now in the child

#

Then anything you do that changes properties of the child like setting signal masks and stuff is recorded

#

When you do exec it will spawn the child process for real with the image you exec'd and the recorded parameters

#

And in the parent will longjmp back to the original fork call, from which it will return the child PID

#

This worked for almost all occurrences of fork

If u add th potato famine command u are a legend

#

Lol

eager yew
# clear minnow If u add th potato famine command u are a legend

that could be an interesting experiment for the memory management system... the potato famine command could take in a certain amount of memory and the kernel would try to reduce the total system physical memory usage to that amount through aggressive page out to disk

clear minnow
#

Nice idea

eager yew
#

and I could even involve the scheduler and use the potato famine command to migrate everything to, say, the efficiency CPUs on heterogenous processors and maybe downclock everything

#

could be funny

#

I am only referring to the y combinator startup accelerator

inner rover
#

Y Combinator tho

#

Yeah I know

#

But did you really get funded by them

eager yew
#

500 big ones

#

and then more as time passes

#

pretty fun stuff

inner rover
#

what's the startup?

eager yew
#

but also job time

inner rover
#

Also aren't you like 16?

eager yew
# inner rover what's the startup?

that's the funny part, we went in with an idea of b2c education software but they said that was a Bad Idea but they "see potential in us" so we're discussing better ideas (i.e. we have no idea)

eager yew
#

a littlun

#

the other people arent but they're not too old

inner rover
#

wtf

eager yew
#

whwat about it

inner rover
#

VC backed startup at 16

eager yew
#

number just a age is

inner rover
eager yew
#

i feel like this server is prime location for such shenanigans

inner rover
#

I've never seen anyone with a YC startup here lol

#

But then again not many people are in SF?

#

Are you in SF?

eager yew
eager yew
#

and yea that's what they said too

#

the Buzzword2Buzzword model is seen as a better option in their eyes

#

claude code is so good at being an overcomplicated regex machine

#

gosh i've probably saved hours just by giving it instructions on a find and replace that was too complicated to do through python/perl

inner rover
#

Why are all YC startup founders indian

eager yew
#

i'm not

#

no one on my team is

#

we out here breaking stereotypes

inner rover
#

If you go on the launch YC page

eager yew
#

inner rover
#

It's all indians

eager yew
#

so progress

eager yew
#

i thought he was born in the us

#

inner rover
#

#

gosh it's all AI slop

palantir invasion

#

i can't believe you can just openly list that as your product

#

how does a tech startup even do this

#

world war 3 is going to be backed by ycombinator

inner rover
#

tbh a lot of the startups there seem dogshit

#

Thought YC was supposed to be the elite

eager yew
#

i'm up against the final boss of larping

inner rover
#

wdym

eager yew
#

nothing here really seems notable

#

it's all just buzzword buzzword buzzword

inner rover
#

Yea

eager yew
#

besides the strike drones

inner rover
#

Which surprises me, since I thought YC was like super hard to get into and was only high quality

#

Holy buzzwords

eager yew
eager yew
inner rover
#

yeah I heard YC was more about investing in the people rather than the idea

eager yew
#

i've tried vibecoding in the truest sense of the word and i just get disasters

#

i even tried doing the whole Prompt Engineering bit too

#

but claude will produce a working program at ridiculous expense in terms of code quality/architecture and maintenance

#

like for web apps it sometimes just uses an error code returned to say "This is Normal, let's just adjust what we sent and send it again"

#

it's just duct tape and sticks again and again

inner rover
#

Well, idk if you saw what Garry tan was posting

#

He's like the world's biggest vibecoder

eager yew
#

oh boy

#

i dont keep up with that scene

#

what has he been posting?

inner rover
#

he was boasting that be was writing like 1M line/week or something

#

And his website was entirely vibecoded and was like 30kloc lol

eager yew
#

i remember i saw some critique of some website, maybe his

#

i remember one criticism of an AI generated site was that it would load two copies of the site, mobile and desktop, even though it would only need one

#

on every load

#

claude spouts baloney less often than chat gippity but it's still a big problem that it has

inner rover
#

I've tried Claude a bit and it wasn't that bad

#

But I didn't try vibecoding an entire app or something

eager yew
#

the commenting and documentation is annoyingly written and overly verbose

#

for example when it makes changes it will yap all about the change and then forget why that code is important to begin with

#

and it talks a lot about how things work and not nearly as much about why they're relevant

clear minnow
eager yew
#

#

do u have an ATA driver?

eager yew
#

yea

inner rover
#

Why are people calling their startups AI-native OSes, when they're not OSes

eager yew
#

it's kind of old and will probably change around

clear minnow
#

i need to steal... ehm take for a bit... an ATA driver

eager yew
#

i advise you steal theirs

i don't quite know if i'm interested in implementing it though

#

hello chat, I have went to go build a dsl-based retargetable assembler

image.png
#

no more charmos work for a bit while i build a compiler or two

#

a tragedy

#

another one bites the dust

eager yew
#

should i add exceptions to my high level assembler

#

-famous last words

#

maybe i could explore.......

#

i wonder at what point this will eventually just become reinvented C

#

when u add local keyword to ur asm dialect (like masm) and now you have to graph color to solve register allocation problems in an assembler

#

actually... hmm i wonder if that would even be possible

#

perhaps a procedure could declare a set of registers available for use by the assembler so it could do this

#

breaking news local man reinvents register keyword

eager yew
#

when the assembler needs IR

placid vessel
#

when the impostor is sus

eager yew
#

my assembler is using the wimmer mössenböck linear scan register allocation optimization, i hope will does not eat me for this because his jackal compiler, from what I understand, uses the poletto-sarkar linear scan algorithm

#

can't believe compiler engineers copied will

#

smh my head

#

how dare they copy the mintia ceo

eager yew
lime wharf
#

honestly this's really cool

tribal maple
eager yew
#

bro has never seen llvm ir

#

#

#

I wonder why more people don't write syntax highlighting that is more featureful for their custom programming languages

#

with the advent of llms getting a lot better at regex I think it's pretty easy to just generate it too

runic pine
#

by more featureful

eager yew
# runic pine by more featureful

as in I see syntax highlighting that just highlights keywords and stuff but not as much to the extent of detecting constants, function invocations, variables, etc

#

perhaps this is just small dataset

#

I've only seen a dozen or so highlighted custom languages

runic pine
#

generally highlighting doesnt actually understand anything beyond syntax

eager yew
runic pine
#

LSPs have a way to tell the editor to highligh specific tokens

eager yew
#

like if you use constants in all uppercase a lot

#

you can guess that

eager yew
#

lsps don't add much

runic pine
runic pine
#

that is the base

eager yew

#

then LSPs can add highlighting

eager yew
runic pine
# eager yew

you just made an argument over something I didnt disagree with lol

#

my point was that LSPs are too slow to provide syntax highlighting

#

which is why things like treesitter do that part

eager yew
runic pine
#

or textmate in vscode 🤮

runic pine
#

xd

eager yew
#

it's a bit like saying programs "have a way" to be written at ring 0 but everyone uses operating systems anywyas

#

it just doesn't follow in that order

runic pine
#

it wasnt meant to follow

#

the point was the capability exists

#

but LSPs are too slow

#

so generally its not used

eager yew
#

I also don't get your point about lsp slow

#

even in large rust codebases my pc does just fine

runic pine
#

highlighting is applied in the rendering pass

eager yew
#

idk how yours is so slow

runic pine
#

if you sit and wait for an LSP to respond in the rendering pass

#

you are fucked

eager yew
#

I don't need to sit and wait though

#

treesitter is slow on my intel core 2 duo laptop

#

anything can be fast or slow for anyone

#

💥

runic pine
#

sigh

#

LSP response times

#

are too slow

eager yew
#

not really

runic pine
#

yes really

eager yew
#

what are your computer specs

runic pine
#

the computer specs doesnt matter

#

just the way LSPs generally work

eager yew
#

I agree that computer specs have no impact on application performance

#

this is why I enjoy playing GTA 5 on my N64

runic pine
#

why do u think people use treesitter instead of providing highlighting via LSP

#

just for fun?

#

LSPs can often take up to 10s to 100s of milliseconds to respond

#

treesitter parsers do the same in under a millisecond

#

that plus the way LSPs are architected it doesnt make sense to use them for highlighting

vagrant cedar
#

Doesn't appear to be LLVM IR?

#

Oh it's a custom thing?
