       Show HN: Munimet.ro - ML-based status page for the local subways in
       SF
        
       During a recent subway outage in San Francisco I decided to build a
       webapp in the spirit of "Do I Need an Umbrella," basically to
       answer the question "Should I take the subway or a bus?"  In the
       interest of learning new tools I decided to vibe code it as much as
       possible.  First, I had Claude Code write a background script to
       download images of the real-time circuit diagram of the subway,
       which are publicly available here: http://sfmunicentral.com/  Next
       I had it build an image labeler tool in tkinter, which turned out
       to need a lot of manual tweaking before I could even get to the
       labeling. Seemed like the right tool for the job, but it would have
       saved time if I'd built it from scratch myself.  The most
       interesting part was turning the labeled image data into
       predictions with pytorch. Claude wrote the initial script fairly
       quickly, but as these things go it required manual tweaking and
       second guessing myself on the images flagged as outliers. I'll
       admit I got embarrassingly far along before realizing that Claude
       hadn't enabled pytorch's GPU support; a real facepalm moment on my
       part.  For those curious, brave, or crazy enough to dive in the
       source code is available here under an MIT license:
