I built a simple, fast transit app for the Bay Area
Hey HN, I built Commuter because I was tired of switching between different apps to check arrival times for BART, Caltrain, Muni, ferries, and more. This app pulls directly from the official 511 API and aims to provide a fast, clean experience focused on real-time departures. There’s no account creation, it’s free to use, and it supports every major transit provider in the Bay Area—from Napa down to San Jose. You can search, favorite lines/stops, and see live countdowns with minimal friction. It’s built entirely in SwiftUI using native Apple frameworks. Happy to answer questions about…
In plain words
Commuter is a transit app for the San Francisco Bay Area that consolidates real-time arrival information from BART, Caltrain, Muni, ferries, and other regional providers into one interface. It pulls data directly from the official 511 API and displays live countdowns with minimal setup—no account required. Users can search for routes, favorite stops and lines, and access information for any major transit provider from Napa to San Jose. The app is built in SwiftUI and available free on Apple devices.

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
