Follow London Trains in 3D
deck.gl based visualiser of the TFL Api + National Rails to be able to track (with minimal drift) a train along the way in London and to the nearest airports. If you pick one from any platform in https://nexttrain.london basically you can share your train journey along the rails. Build to test Cloudflare workers and their infra along with deck.gl performance that is incredible in my opinion.

In plain words
Follow London Trains in 3D is a visualization tool that tracks trains in real-time across London's Transport for London and National Rail networks using live API data. Users can select a train from any platform and follow their journey along the rails to nearby airports, with the ability to share their route. The tool uses deck.gl for 3D visualization and Cloudflare Workers for infrastructure, demonstrating high-performance mapping capabilities for London's rail system.

From the sources
Just a small utility to visualise and share train rides along London with the option to share it, should work even with no Internet because it uses the TFL and Trains data.
Board a live London Tube train and ride it through a 3D London. Real-time positions reconstructed from TfL open data.

Railway2021 · railway.com · ▲405Hacked together a service in Go https://github.com/xlab/cdn-s3-go that routes content request to any arbitrary S3-compatible bucket. Some infra providers are offering free egress, but buckets are only private (hello Railway), and not geo-distributed. An L4 balancer will cost a fortune (hello Cloudflare). cdn-s3-go solves this by looking up objects, generating a pre-signed URLs and redirecting the clients directly. Free egress, cheap public geo-distributed CDN!
Tokyo TrainsAug 2026 · greggman.github.io · ▲13Semi inspired by the 3d Shinjuku station that was posted again recently, I noticed it was missing a large portion of the "complex" where "complex" is defined loosly has how far you can walk without stepping outside. So I asked Claude to make a 3d map of all Tokyo Trains, no libraries, and let you zoom into stations, and the first version with both map and the Shinjuku complex was ready in about 3 hours. It spent another 7 or so in various nit picky things I asked for to get to the current version. I know these will only get better but I think the thing I find most interesting is no libraries…

Talanoa▲337Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

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…
