Introducing WEBCAT: Web-based Code Assurance and Transparency

In this post, we introduce Web-based Code Assurance and Transparency, a project that supports verifiable in-browser code for single-page browser applications. Along with this post, we are publishing the WEBCAT project repository; follow-up posts will provide more detailed information.

Atmospheric Automated Development

Marking a piece of feedback 'planned' kicks off an autonomous coding agent that implements it and opens a draft PR. Built with userinput.app, airglow, and GitHub Actions, without touching the app.

On Rendering Diffs

A technical deep dive into how we built the @pierre/diffs package and CodeView component for zero-blanking diff rendering at any scale.

contextual animation stuff in Sleight of Hand – joe wintergreen internet zone

I’ve been working for the last week or two on a system to streamline contextual or scripted animation stuff in Sleight of Hand, a stealth game with a lot of systemic interaction aspirations. I built an interest source system a while back for coordinated investigations and dynamic behaviours, and while some of those interactions have been doing cool stuff on the animation side (a guy might rip open a wardrobe you’re hiding in, for example), it has tended to involve a lot of more-or-less-boilerplate Blueprint every time; it’s not been as easy as it should be to drop in what Half-Life called a “scripted sequence”. This fortnight’s work has improved this a great deal, and I’ll tell you for why, and perhaps you will benefit from doing something like this yourself.

Imagine every pixel on your screen, streamed live directly from a model. No HTML, no layout engine, no code. Just exactly what you want to see. @eddiejiao_obj, @drewocarr and I built a prototype to see how this could actually work, and set out to make it real. We're calling it Flipbook. (1/5)
