Show HN: Gemma 4 Multimodal Fine-Tuner for Apple Silicon
About six months ago, I started working on a project to fine-tune Whisper locally on my M2 Ultra Mac Studio with a limited compute budget. I got into it. The problem I had at the time was I had 15,000 hours of audio data in Google Cloud Storage, and there was no way I could fit all the audio onto my local machine, so I built a system to stream data from my GCS to my machine during training.<p>Gemma 3n came out, so I added that. Kinda went nuts, tbh.<p>Then I put it on the shelf.<p>When Gemma 4 came out a few days ago, I dusted it off, cleaned it up, broke out the Gemma part from the Whisper fine-tuning and added support for Gemma 4.<p>I'm presenting it for you here today to play with, fork and improve upon.<p>One thing I have learned so far: It's very easy to OOM when you fine-tune on longer sequences! My local Mac Studio has 64GB RAM, so I run out of memory constantly.<p>Anywho, given how much interest there is in Gemma 4, and frankly, the fact that you can't really do audio fine-tuning with MLX, that's really the reason this exists (in addition to my personal interest). I would have preferred to use MLX and not have had to make this, but here we are. Welcome to my little side quest.<p>And so I made this. I hope you have as much fun using it as I had fun making it.<p>-Matt
Show HN: Is Hormuz open yet?
I built this because I was interested in the data. Didn't fully get it to what I wanted, but thought I'd share it nonetheless. Maybe someone has better data sources they could share!<p>Turns out live ship tracking APIs are expensive so I manually just copied the json from <a href="https://www.marinetraffic.com/en/ais/home/centerx:57.4/centery:26.4/zoom:8" rel="nofollow">https://www.marinetraffic.com/en/ais/home/centerx:57.4/cente...</a> I'll probably have an ai agent do the same thing on some cron interval, if this gets any fanfare.<p>To actually know if the port is open without live ship tracking I found <a href="https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a1730" rel="nofollow">https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a...</a> which was perfect, except it has 4 day lag!<p>I also thought of adding news feed parsing or prediction market data to get a more definitive answer on if it's open right when you load it, but I spent a few hours and am gonna move on for now.

Show HN: An interactive map of Tolkien's Middle-earth
An interactive map of Tolkien’s Middle-earth, with events from across the legendarium plotted as markers.<p>I have been commuting a fair bit between the East and West coast, and thanks to American Airlines' free onboard WiFi, I was able to vibe-code a full interactive map of Middle-earth right from my economy seat at the back of the bus.<p>It's rather amazing how much an LLM knows about Tolkien's work, and it was fun to delve into many of the nooks and crannies of Tolkien's lore.<p>Some features:
- Plot on the map the journey of the main characters in both The Hobbit and The Lord of the Rings.
- Follow a list of events in the chronological Timeline
- Zoom in on the high-def map and explore many of the off-the-main-plotline places
- Use the 'measure distances' feature to see how far apart things are.<p>I also had a lot of fun learning about tiling to allow for efficient zooming.<p>If you are anything like me, this should provide a fun companion to reading the books or watching the movies (note that on this site, I followed the book narrative, and did not include Peter Jackson's many departures)<p>If you get the chance to check it out, I would love more feedback, and if there is demand, I might do the same for Game of Thrones.

Show HN: Gemma Gem – AI model embedded in a browser – no API keys, no cloud
Gemma Gem is a Chrome extension that loads Google's Gemma 4 (2B) through WebGPU in an offscreen document and gives it tools to interact with any webpage: read content, take screenshots, click elements, type text, scroll, and run JavaScript.<p>You get a small chat overlay on every page. Ask it about the page and it (usually) figures out which tools to call. It has a thinking mode that shows chain-of-thought reasoning as it works.<p>It's a 2B model in a browser. It works for simple page questions and running JavaScript, but multi-step tool chains are unreliable and it sometimes ignores its tools entirely. The agent loop has zero external dependencies and can be extracted as a standalone library if anyone wants to experiment with it.

Show HN: GovAuctions lets you browse government auctions at once
I've long been into finding deals on government auction sites (seizures, surplus sales etc.) - right now for example San Diego DHS is selling 26 tons of lead shot, with bidding starting at $1,000 ¯\_(ツ)_/¯<p>It has historically been extremely tedious though: scanning dozens of janky sites which have interminable page loading times; back buttons take you all the way back to the homepage etc.<p>The site I built - GovAuctions - lets you search every government surplus auction at once. You can filter by location, category, and price, save items to a watchlist, and get alerts when new auctions match what you're looking for.<p>Let me know what you think, if you have any suggestions, and if you find any deals in your area!
