Show HN: Rotunda - A browser built for agents with simulated typing https://ift.tt/18zlnNY

Show HN: Rotunda - A browser built for agents with simulated typing Hi HN! Pierce here. Rotunda is a firefox fork primarily intended for agent use, which I’ve been hacking on nights/weekends. There was a [lengthy]( https://ift.tt/5VtZkBr ) discussion last week on how expensive computer use models are. The cost is going to drop eventually, but I think on some level it's still usually the wrong primitive. The web gives us access to beautiful structured formats, plaintext, etc... why throw that away if we don't have to? I realized at some point that for 99% of automations I just want agents to be able to control my Chrome instance. But that’s easier said that done: CDP (the Chrome automation protocol) leaks a ton of state about being programmatically controlled, either by toggling window attributes or by running `page.evaluate()` commands right in the page context. Plus if you look at an automation running it's pretty obvious what happens: the mouse jumps around, fields are fi...

Reserve Parking in a City-Owned Garage: SFMTA Makes Parking Easier for Everyone

Reserve Parking in a City-Owned Garage: SFMTA Makes Parking Easier for Everyone By Pamela Johnson Parking in San Francisco can be challenging, but we’re here to help make it less stressful. We recently announced two new mobile apps that let you pay for parking by phone and even get alerts when your meter is winding down. Now, our teams are making it easier to find parking, too! Our online parking reservation system is expanding to cover the majority of SFMTA-owned garages across the city. That means you can reserve parking at garages located conveniently near the ballet, opera, symphony, theaters and shopping districts. The best part: rates at SFMTA garages are typically 30–40% less than... Published 2026-05-13T00:00:00Z https://ift.tt/7Rswgc3

Show HN: Neural window manager, neural network moving windows from mouse actions https://ift.tt/rcYLKzq

Show HN: Neural window manager, neural network moving windows from mouse actions I'd been mulling over this crazy idea for a while. Can programs be generated? Inspired by recent advances in world models, I wondered if we could do away with source code and generate pixels directly and interactively. As an experiment to answer this, I set out to create a neural window manager, training a neural network to predict what the screen would look like next. Basically, the idea was to generate the next frame based on the last two frames and the mouse position. That's it: moving windows without programming an event system, just a simple convolutional neural network guessing pixels. To implement the experiment, I used Pygame to simulate a turquoise desktop background, a gray window with a navy blue title bar, a white cursor, and four colors in total. Then, a bot randomly dragged the window, and I recorded everything, processing the frames as color index matrices (not RGB, to avoid complica...

Show HN: Statewright – Visual state machines that make AI agents reliable https://ift.tt/nczyieZ

Show HN: Statewright – Visual state machines that make AI agents reliable Agentic problem solving in its current state is very brittle. I fell in love with it, but it creates as many problems as it solves. I'm Ben Cochran, I spent 20+ years in the trenches with full-stack Engineering, DevOps, high performance computing & ML with stints at NVIDIA, AMD and various other organizations most recently as a Distinguished Engineer. For agents to work reliably you either need massive parameter counts or massive context windows to keep the solution spaces workable. Most people are brute forcing reliability with bigger models and longer prompts. What if I made the problem smaller instead of making the model bigger? I took a different approach by using smaller models: models in the 13-20B parameter range and set them to task solving real SWE-bench problems. I constrained the tool and solution spaces using formal state machines. Each state in the machine defines which tools the model can a...

Fix It! Week Is Back May 18, 2026: Taking Care of Muni from the Ground Up

Fix It! Week Is Back May 18, 2026: Taking Care of Muni from the Ground Up By Sevilla Mann Fix It! Week subway closures allow us to do maintenance work that makes our system safer and more reliable. The second Fix It! Week of the year is coming up on May 18, 2026, and we’re here to help you prepare. These Fix It! Week closures ensure our crews can move safely as they carry out critical repairs and inspections. Their work helps to keep our system safe and reliable for everyone. The details: When: Market Street subway service will end early at 9:30 p.m. each night from Monday, March 18 through Thursday, May 21.

Show HN: Gigacatalyst – Extend your SaaS with an embedded AI builder Hi HN, I’m Namanyay from Gigacatalyst (link: https://ift.tt/edyx5Ho ). Gigacatalyst allows sales, CS, and users to build one-off features, so your SaaS can support long-tail customer workflows and engineers aren’t pulled away from the roadmap. When you sell software to large businesses, you realize that each customer needs their own workflow and features. Traditionally, this either means long engineering roadmaps or the customers end up using workarounds. But what if everyone could build their critical missing features just by talking to an AI? That’s what we do at Gigacatalyst. We provide an AI customization layer for your customers, CS team, and sales team to build these missing critical workflows without needing any engineers at all. Think Lovable, but built on top of YOUR platform. We connect to your product's APIs, learn your data model and design system, and let non-technical users build governed apps via...
