So, if this does help reduce the cost of tokens, why not go even further and shorten the syntax with specific keywords, symbols and patterns, to reduce the noise and only keep information, almost like...a programming language?

I built this very simple tool, inspired by Hacker News' simple yet convenient UI, to create a community around the latest freight developments (I run a last-mile delivery fleet in NYC). I'm mostly posting about NYC freight news, but would love to get other freight enthusiasts/professionals/insiders to join and share their insights and thoughts, not just in NYC or even the US. The tool is simple, with almost no JS and all SSR, to keep things simple. It's still running on my dev server at home, so uptime is not guaranteed. Open to any feedback on this.

I'm currently working on building a local delivery service using electric cargo bikes in NYC: https://hudsonshipping.co. We are planning to launch our first pilot in early 2026 with our first customers in Brooklyn. We've built all of the tech in-house to manage the fleet, deliveries and optimize our routes. If you know of anyone that would like to be a part of the pilot program, feel free to reach out to me!

If a ping to a specific IP times out, I wouldn't say the IP is blocked. It could be that ICMP specifically is blocked, following some network rules on the firewall. This is pretty common in entreprise networks to not allow endpoint discovery. I could be missing something and happy to be corrected here, but I was surprised to read that.

Still working on building a local delivery service in NYC using electric Cargo Bikes, at https://hudsonshipping.co. We're aiming to launch our first pilot in early 2026 in Brooklyn!

Any idea why Spain and Portugal have such small isometric zones? An obvious factor is the mountains in the North, but I'm surprised there isn't easier access between the Iberian peninsula and France

So running a SQL query and returning GeoJSON? Sorry that didn't work - hopefully you can work on another system like this soon, with someone who actually understands the benefits of tiles!

Thank you! I'll take a look, this looks great

Awesome, good job! Did you implement likes and polygons too?

This is amazing, I hadn't come across these tools, these are extremely useful!

I have not looked at PMTiles, so far everything holds nicely generated in memory, so I haven't had the need to store this information. I'll keep it in mind.

Any idea why Mapbox GL JS doesn't support GeoJSON vector tiles?

I've found some waterways traffic data, but it seems to be previous day usage data, and not real-time usage or position. I'll dig to see if there is some info, as that would add some value to the dashboard for sure!

Honestly, simple curiosity + wanted to keep it in Go

Thank you - I will watch that with my coffee. I also realize this means I set the extent to 512 in the mvt file - that means I won't benefit from that subpixel precision you mentioned - I'll update the code and test it out

Ah, I was missing that bit of information, and it explains why I was seeing these two values. Thank you stevage, I'll update the post with this info and cite you.

Hi HN! This is my first blog, inspired by many posts read here. I attempt to explain how Vector Tiles in GIS tools are constructed from scratch, and how easy it is. This also sets up future blog posts about MapLibre tiles as well as some tricks in the backend to pre-generate the MVT files to serve them up quickly, and update tiles for real time updates on a map. I'll be happy to answer any questions or feedback!

This looks great! I've been planning on adding NYISO power data to the NYC Dashboard (https://dash.hudsonshipping.co), so this is very encouraging to see! I unfortunately don't think the US has such granular data - I love seeing the interconnectors to other countries.
