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…

This is a service I've built to provide equirectangular cloud maps of the whole Earth, updated every 3 hours, for free. It's based on infrared and visible light data from EUMETSAT, processed to enhance the clouds and try to reduce the impact of surface temperatures on the final image. I built it because it's surprisingly hard to find these kinds of images in a format that's useful to developers and hobbyists. I was building a 3D ISS tracker and wanted to include live clouds but couldn't find anything good, so I got sidetracked, and here we are.

The concept for metiq.space came after playing Global Magnates with friends and realizing how fragmented live global data is. ships, aircraft, satellites, ports, weather, hazards, infrastructure, cyber, and public datasets all exist, but they usually live in separate tools and maps. The goal was to build one interactive 3D globe where live public data could be visualized by latitude, longitude, and altitude. Surface data stays on the globe, while aircraft, satellites, and other above surface things can be represented in actual 3D space instead of being flattened onto a map. The outcome is an…

Over the weekend I was discussing the latest news relating to open weights with some of my non-techie friends. After 30 mins of waffling, I realised it is quite a long and interesting story, with many twists and turns. I've always wanted to create a 'long scroll' story, but have never found a suitable story to tell. This felt like a fun weekend project to undertake. The story itself doesn't have too many scroll effects (which is probably a good thing), it was more about trying to tell a story with a certain style that wouldn't really fit on my personal blog. Would love to get your feedback…

Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…

[I'm the author] Spall is a web-accessible profiler that I made to help my web-dev friends load gigabyte+ JSON traces without lunch-break-long load times. Recently, Spall got experimental support for auto-tracing with binary traces (along with an in-progress native-port, to give it more memory headroom), which was used to help track down and fix some hard-to-spot lock contention issues in the Odin-language compiler. I demoed it at the Handmade Seattle conference in October, https://guide.handmade-seattle.com/c/2022/spall/, with a head-to-head against Perfetto,…

I made a web app to generate 3D models of real places on earth from land cover and elevation data. Click anywhere on the map to get a polygon, and then click "generate". It should work at most scales, but if your watershed or region selection is too large, the result can be less exciting because it's so flat. As a warning, the 3D models can sometimes be too much for my phone. It's nicer on desktop. I'm still working better on mobile support. The land cover data I'm using gives a cool effect, but at some point I'd like to add in global imagery and clouds. The backend is a Python thread…

I created this a year or so ago but recently made updates and I thought people might like to know that it exists. I made this to easily send links or text to someone else verbally, like over the phone or over voice chat (which is what I made it for). The goal is to be able to tell the link to someone else without being ambiguous or needing to spell it out, so I grabbed the words off a Grade 5 level dictionary. I understand that the domain itself doesn’t qualify but I’m trying to get a better domain.

Edgemetry▲99I've been building a lot of landing pages and small sites lately, and i wanted analytics on them. Google analytics was the obvious first option, but i didn't want it for privacy reasons. Also, some privacy blockers block them. Plausible was the next best thing, but having a VPS for sites which that doesn't get too much traffic, felt too much. So i built Edgemetry. Its a worker, a bit of frontend, and a D1 database. Everything runs in Cloudflare's free tier. If you've got a site that doesn't get ton of traffic but you still wnat to see your visitors and their actions, give it a go.
