Show HN: wavecat – a fully local personal agent that watches your screen https://ift.tt/G3kPHSQ
Show HN: wavecat – a fully local personal agent that watches your screen wavecat is a fully local personal agent that watches your screen. It develops a rich understanding of your needs and goals by constantly viewing your activity. Don't worry, none of your personal data ever leaves your computer since all the models run locally. I think it's something cool to show a feature that local agent systems can do that cloud systems can't. If you have a beefy Apple Silicon Mac or a nice GPU, you should be able to run it! https://wavecat.a…

Show HN: Hacker News on a Train Station Style Flip Board https://ift.tt/bolsvBp
Show HN: Hacker News on a Train Station Style Flip Board Although the page itself is more just fun to have made and look at (I like the flip sound), the fun part is how I made it to verify the (and I hate to say it) vibe host service I've been working on. The recent flip board back and forth's on Twitter (X) are what inspired me. The idea here is that people (like me or you) can create something neat like this, and others can remix it, change it and publish their own version. This is that all in action and it worked great. I wrote a bl…
Show HN: Overfitted a 900KB Transformer to Compress a 100MB CSV into 7MB https://ift.tt/SwPYbdL
Show HN: Overfitted a 900KB Transformer to Compress a 100MB CSV into 7MB I built an experiment that uses an overfitted transformer and arithmetic coding to compress individual files. Instead of training the model to generalize, I train a 900KB transformer to memorize a single file and predict the next byte. Those predictions are fed into an arithmetic coder to produce the compressed output. On a 100MB NYC taxi CSV, it compresses to about 7MB (~0.5 bits/byte). On a 100MB slice of enwik9, it compresses to about 21MB (~1.68 bits/byte). It's p…
