Playdate Season 2 review: Taria & Como and Black Hole Havoc

We've officially made it to the end of Playdate Season Two, and what a season it's been. Despite having half the number of titles as Season One, this latest round of weekly game releases has made a much stronger impression (on me, at least). If nothing else, it's just been cool to experience the new games in real time with other Playdate owners all at once, which the staggered rollout of the console didn't really allow for with the first season. In an email ahead of the final release, the tea

Show HN: Simple wrapper for Chrome's built-in local LLM (Gemini Nano)

Chrome now includes a native on-device LLM (Gemini Nano) starting in version 138. I've been building with it since it was in origin trials, it's powerful but the official Prompt API is still a bit awkward:

- Enforces sessions even for basic usage

- Requires user-triggered downloads

- Lacks type safety or structured error handling

So I open-sourced a small TypeScript wrapper I originally built for other projects to smooth over the rough edges:

I extracted the safety filters from Apple Intelligence models

I managed to reverse engineer the encryption (refered to as “Obfuscation” in the framework) responsible for managing the safety filters of Apple Intelligence models. I have extracted them into a repository. I encourage you to take a look around.

Show HN: Pixel Art Generator Using Genetic Algorithm

This project is a simple but fun demonstration of a genetic algorithm applied to image generation. It starts with a population of random images and evolves them over generations to resemble a target image. The output is an animated GIF that shows the entire evolution process.

Show HN: I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics

https://lisagui.com/info.html

This is a web OS I wrote in vanilla JS that looks like the Apple Lisa Office System (1983-85), with other contemporaneous influences and additional improvements and features. It's currently in alpha and isn't remotely bug free. I had been holding off on posting this here until it was somewhat presentable and useful. Please note; the Lisa conforms more literally to the desktop metaphor than most modern

Appliance energy labels for washing machines are pointless

OPINION: There’s nothing wrong with getting manufacturers to make appliances more efficient, but the energy labelling system for washing machines has become hopelessly out-of-date, to the point where they’re not useful in making a buying decision.
