i built an entire x86 CPU emulator in CSS (no javascript) you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS

x86 segmentation maps memory references through segment registers. It is still used in modern x86-64 for FS/GS, especially thread-local storage and kernel per-CPU data. In sandboxing, segmentation can restrict untrusted code to a fixed memory region. MIT 6.858.

💡 CSS Tip! In Anchor Positioning, you can use position-area to place an element relatively to its anchor, but there are 36 different positions !? 👀 No one can memorize them all, so I've created an interactive demo from where you can get the code.

See the CPU execution, Pipeline stages and Caches in action. This emulator animates the high level CPU and Cache state-machine. You can track the state (fetch, decode, execute, memory access, write back and ) of a given instruction... Try it here:

Code Execution If you ask Grok to generate code, you can quickly see how it runs in a “preview” tab. You can preview HTML snippets, run Python, C++, Javascript, Typescript and bash scripts.

The worst thing about dealing with C (and C++ to an extent) code is understanding and debugging macros that you didn't write. Here are a couple ways of how to deal with them!

deploy to preview in under 3 seconds cold with vmux! i told a friend i didnt have any modal credits left on saturday, by monday night i rolled my own cpu modal - seems prevalent if llms can code you should give them easy access(besides ssh) to provision, run code, and deploy containers fast

TypeScript was inspired by a strange ask from the outlook team. Anders Hejlsberg(Anders Hejlsberg) - creator of C#, TypeScript, Turbo Pascal & Delphi - tells us how TypeScript was born: “The world started building larger and larger applications in JavaScript. We saw that externally, but also internally. One of the trigger events was when the outlook team came to see the C# team and asked us whether we would pretty please productize this thing called Script#. And we go, well, what is Script#? It's this cross compiler that allows you to cross compile C# into JavaScript such that you can basically treat JavaScript as an instruction language and run your C# apps in a browser. Why would anyone want to do that? Well, because then you can get a grownup programming language with grownup tooling. You can use Visual Studio, you can have projects. You can do all of these wonderful things that you can't do with JavaScript because JavaScript is just the scripting language with shitty tooling. And we thought, well, perhaps a better approach would be to fix JavaScript. I mean, surely you're not going to be best of breed in the JavaScript ecosystem by telling people to write in a different programming language”

here's a small project i put together recently - a custom "bare-metal" protected-mode x86 NES emulator. it fits into 1MB RAM and loads ROMs from a floppy disk, no OS required. if you want to turn your old PC into an awkward NES clone with bad sound emulation then look no further.

I used Codex 5.6 Sol to get RollerCoaster Tycoon 2 running natively on iPad. This is built on OpenRCT2, the open-source engine their team has poured years into. I compiled it to a native ARM64 iPad app and built the touch controls on top. No emulator, no x86, no streaming from a Mac. Coaster building, scenarios, and park management all work by touch. First time I've seen RCT2 run natively on iPad. Open sourcing it all below.

Can GPT-4 code an entire game for you? Yes, yes it can. Here's how I recreated a Snake game that runs in your browser using Chat GPT-4 and Replit ⠕, with ZERO knowledge of Javascript all in less than 20 mins 🧵

Inspired by Ammaar Reshi getting C&C Generals running natively on iPad, I did the same for Warcraft II using Codex 5.6 Sol. It's the open-source Stratagus/Wargus engine compiled for ARM64, rendering through Metal via SDL2. No emulator, no x86, no streaming from a Mac. Campaigns, skirmish, and save/load all work, with touch controls. First time I've seen Warcraft II run natively on iPad. Open sourcing it all below.

Agents live in terminals and tabs, people juggle between them. We built . Figma for agents: manage and run agent teams with no code. One workspace where humans and agents actually work together. Comment what you’re working on and we’ll build an agent team to help you.

Available now in Visual Studio Code Insiders, you can select and add elements directly to Chat! After opening any locally-hosted site via the built-in Simple Browser, click "Start" on the toolbar and select the element you want. This will attach a screenshot of the selected element, as well as the HTML and CSS of that element.
