What it does
Trails can get busy, and others stay empty, but how do you know? We built Trailsense to answer that. Our solar-powered nodes count hikers using anonymized wifi probe requests, the pings a phone sends while scanning for known networks. A dashboard turns those counts into a clear view of how busy each trail is over time. No cameras, no app for hikers to install, and no personal data ever leaving the device.
Trailsense provides privacy-friendly visitor counting for trails and remote outdoor areas.
Measure visitor flows with a simple, privacy-friendly system designed for outdoor environments. Many municipalities and tourism regions don’t have accurate data on how their trails are used. Existing solutions are often expensive, difficult to maintain, or not designed for remote environments. As a result, important decisions are often based on assumptions instead of real data. Trailsense provides an easy way to measure visitor flows using small, off-grid sensor nodes. The system works without cameras and does not collect personal data. Trailsense does not use cameras or any kind of visual recording. This means no images, no videos, and no possibility to identify individuals. The system…from trailsense.at

I made an offline-ready hiking trail companion app2022 · github.com · ▲475Hi HN! This is a trail companion web app (think AllTrails) I hacked together in a couple weeks time. I was inspired to create this project while training for an extended backpacking trip. My motivation was to create a UI tailored exactly to my liking, and to be able to track my progress along the trail without draining my battery. I also wanted to experiment with PWA technologies. I successfully used it on my five day adventure along the Knobstone Trail in southern Indiana, and even though it's web-based it hardly consumed any battery life on my old first-gen Pixel XL. It's set up currently…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
