   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
7. ajd555 Sep 4, 2025 parent

   Good to know - thank you!
8. ajd555 Sep 4, 2025 parent

   Awesome, good job! Did you implement likes and polygons too?
9. ajd555 Sep 4, 2025 parent

   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
14. ajd555 Sep 4, 2025 parent

    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.

    The First Tycoon by T.J Stiles - a great biography (easy to read) about Cornelius Vanderbilt, and you get a lot of amazing history on NYC and the rise of modern transportation and freight (steamboats to railroads). I recommend to anyone interested in NYC history and supply chains in general

    This is great, congrats on getting it out!
20. ajd555 Aug 31, 2025 parent

    I luckily haven't felt that, but I'll look into eleventy, thanks!

    I've been using Astro for close to a year, and so far it's been quite enjoyable. I hope it doesn't follow in Hugo's footsteps
22. ajd555 Aug 30, 2025 parent

    Good find - it is pretty crazy how this impactful change (I can see the logistics/supply chain subreddits abuzz with this news) isn't at all clearly defined. Per your link:

    > They cite ambiguity about what kind of goods are covered by the new rules, and the lack of time to process their implications.

    Ah didn't even see that - I think my brain wanted it there because of the original title (Trump's)

    Definitely odd to see that the default is to let this keep happening, counterintuitive is a word that comes to mind

    Great read - as a young startup with Chase, this is an interesting story. As Mitch says, this isn't inherently an issue with Chase, but interesting bank behavior. I'll be sure to keep this story in mind, if we ever get to these amounts of cash!

    I use a few bitnami charts, and I'm now going to have to migrate them. For everyone here surprised that anyone would use them, here's some context from my perspective: as a small startup, having a pre-configured Kafka chart was a lifesaver, where I only needed to tweak the parameters I was interested in, which took me a lot less time than setting up a whole Kafka environment from scratch. It was relatively quick to setup, and felt like the right move to put something like Kafka in production (and not have to pay for Confluent when everything else is self hosted)

    Ah - thank you for pointing that. It's a bug that happens when I restart the process, and I don't catch the error. I'm fixing it for the next release at the end of the week
