Hoodmaps Meets 4chan

I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…

  • I built a real-time OSINT dashboard pulling 15 live global feedsMar 2026 · github.com · ▲312

    Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop…

  • My first programming project – userscripts to change forum UIs2024 · github.com · ▲89

    Hi, I'm Will. I'm 24, autistic, and have OCD tendencies. I'm learning to code and this is my first public project. I’d really appreciate your feedback and encouragement! This project lets me solve some of my OCD problems online. There are a couple of parts of the forums that I visit – Space Battles, Sufficient Velocity, and Questionable Questing – that I want to remove. Specifically, I hate seeing indicators of how much is left in a forum thread, because I keep thinking about how much content is left. It stops me from immersing myself in the story. It stressed me out. Before I learned to…

    Everything that would be here is in the README. I hope this gets big, it has tons of potential.

    my weekend project, understanding the Silk Road anonymous marketplace2011 · burntbrunch.github.com · ▲40

    This was more of a sandbox to play with Raphael and Flot than anything else but I think there are some interesting statistics in there. It'd be awesome to do this over time but I really don't have the spare time required.

    USearch Images demo in 200 lines of Python2023 · usearch-images.com · ▲9

    Hey everyone! I am excited to share updates on four of my & my teams' open-source projects that take large-scale search systems to the next level: USearch, UForm, UCall, and StringZilla. These projects are designed to work seamlessly together, end-to-end—covering everything from indexing and AI to storage and networking. And yeah, they're optimized for x86 AVX2/512 and Arm NEON/SVE hardware. USearch [1]: Think of it as Meta FAISS on steroids. It's now quicker, supports clustering of any granularity, and offers multi-index lookups. Plus, it's got more native bindings than probably…

    hipchan, an anonymous sharing site built with 1 page js2010 · hipchan.com · ▲9

    URL: http://hipchan.com/ The story: after seeing this on HN http://news.ycombinator.net/item?id=1940089 and seeing a comment about 4chan, I decided that I could build something that embraces the 4chan idea. Even though the story today is 'social' I really think that anonymity will continue to have a place in future communities. It was supposed to be a weekend hack, and it was! 95% of the features were worked out in the weekend following, but somehow testing lasted till today... Primary feature: The ability to have * boards. For example: http://hipchan.com/#hn The Tech:…
