people say being clicker trained is weird and yet they freak out over the discord ping sound

i was also trying to play around with the base offset and couldn't figure out what tf the point of that was
why is it loaded at 0x100

Rebane
uh because uh
youre gonna love this

Sylvie
also it gets so so much slower if i increase the number of memory cells beyond like 0x700

Rebane
see i downloaded this strange program

[Image of an ancient-looking program called i8068]

and i couldnt figure out how to use it
but every time i loaded my binary it loaded at 0x100
so i was like
hmm
maybe i should load it at 0x100 in css too

Sylvie

Wikipedia article: Qrpff

This article relies excessively on references to primary sources. (September 2011)

qrpff is a Perl script created by Keith Winstein and Marc Horowitz of the MIT SIPB. It performs DeCSS in six or seven lines. The name itself is an encoding of "decss" in rot-13. The algorithm was rewritten 77 times to condense it down to six lines.

i personally think a programming language doesn't need to be able to run complex logic to be one, but it's really difficult to convince people of that so it's just easier to make it run x86 assembly instead

i think faq-s should be written in a way where you can read through them like a story if you're bored

Why does it only work in Chrome?
This project uses a few CSS features, such as if() statements, style queries, and custom @functions, that are not available in all browsers. At this time, it's only compatible with Chromium-based browsers, but hopefully that'll change at some point since the features used are in the CSS spec. I usually make sure to target Firefox in the projects I make, but it's just not realistic for me with this one.

What ai/model/llm do you use?
I do not use ai. I don't think you can build a project like this with an llm.

Can it run doom?
No, not in its current state.

Have you figured out how to center a div?
If you feel the need to ask, please read this.

You were so preoccupied with whether or not you could that you didn't stop to think if you should
idk why everybody keeps saying that, obviously i thought about whether i should first and came to the conclusion that it would be fun and cool asf to do it

added some more things to the x86css faq that people kept bringing up

fyi for most feature checks you should use the @supports at-rule - i just couldn't figure out how to use it for if statements and functions, so i'm just straight up running code and seeing if it acts as i'd expect

not much, endianess is pretty easy to deal with on a 16bit (2byte) system

ur already light-years ahead of most developers if u figure out some way of positioning stuff instead of just complaining about how impossible centering a div is

it can't work, the message shows up based on actual feature checks, not browser detection

yeah moxie seemed really cool!! i had parts of it implemented in css but then i figured it'd be a bit annoying to do 32 or 64 bit arches so i wanted to target something 16bit

u never have to worry about ur code quality when posting on hackernews cuz they never read it anyways and just post their thoughts based on the title

writing C code for my ~5Hz CSS CPU has truly made me realize just how fast computers are

the original 8086 (from 1978) was 5MHz, which is already 1000000x faster than my CSS CPU, and that's *nothing* compared to modern hardware
