Alex Cheema at Exo Labs presents llama98.c — a modified llama2.c by Andrej Karpathy that runs on Windows 98.

• 260K model: 35.9 tok/sec
• 15M model: 1.03 tok/sec
• 1B model: 0.0093 tok/sec

A few days ago, Alex shared a behind-the-scenes look on how it was made. The thread covers using FTP to transfer model weights and inference code to discovering how to build modern software for Windows 98:

On the topic of compiling for old hardware, Sam D’Amico shared DJGPP — a relatively modern port of GCC and interesting on its own!

React Scan by Aiden Bai automatically detects performance issues in React apps. From the website:

Previously, existing tools required lots of code change, lacked simple visual cues, and didn’t have a simple, portable API

Instead, React Scan:

• Requires no code changes – just drop it in
• Highlights exactly the components you need to optimize
• Available via script tag, npm, CLI, you name it!

React Scan will soon show what props caused a component to render as well:

And allow for recording and replying renders!

You can visually inspect React trees with a couple lines of code with the excellent Bippy toolkit by Aiden Bai.

import { Inspector } from 'bippy';

<Inspector enabled={true} />

Works with React v17-19!

Lots of respect for people who keep old URIs working. It becomes a lot easier when URIs are designed like the rest of your software.

Tim Berners-Lee invented the World Wide Web in 1990. He wrote the first browser on a NeXT Computer.

Using a mix of lowercase and uppercase causes pain on case-insensitive file systems like APFS by default on macOS.

Changing file case in Git commits is a bit weird already. My preference is to keep with existing conventions instead of injecting my own but if you’re starting a new project skip the (lower) camel case.

In the last week, I imported a TypeScript file with a different case than what was on disk by mistake. Some tools accepted it. The import-x/extensions ESLint rule failed because of the case mismatch. The error message there did not suggest anything about letter case.
