Who needs Google Maps and a browser when you can have interactive maps over SSH? Made with Rust, ratatui for terminal rendering on the backend, and xterm.js for terminal emulation on the front-end.

We aren't changing the data, just changing how the graph is displayed.

We just haven't crawled your site yet! There's a lot of links so we can't crawl them all :(

The hairball was much worse before. I used a lot of techniques from this paper [1] to make it look decent and a bunch of other heuristics based on other papers to make it look informative. [1] https://jgaa.info/accepted&#x2F

I started off with my favorite blogs and recursively explored from there based on what they linked to.

To get their topics? I used a basic louvain community detection algorithm, then put all the URLs into GPT with some few-shot prompting tricks to get it to output a particular topic. There's some heuristics to break up giant communities

Yeah I used cytoscape before but it didn't have the full customization that I wanted. Besides the performance issues, there were some problems I couldn't have solved without a custom renderer - if many lines overlap, how should t

Nice! I looked through the logs and saw that you linked to it in this article: https://www.adithyabalaji.com/datascience/2021/05/17/Analyzi...

I scraped my favorite blogs and made a graph from the domains that each blog links to. You can see clusters forming of websites that talk about similar topics, like crypto, rationality, Canada, India, and even postgres! The visualization wa

You can adjust the time where it says "Maximum trip duration".

Not sure if something like this exists yet, but certainly do-able within my implementation. For example, when choosing the best route, it penalizes every transfer by 120 seconds [1]. Therefore, a route that takes 2 minutes longer is equival

Hey, thanks for the feedback! Greatly appreciated. 1. Yes I think "locking" makes sense. The entire action of viewing the paths to different destinations still needs to be polished up, especially for the mobile version as well. Wh

Hahaha you discovered it! Originally I had waterloo because I study there, but I removed the city from the picker as I thought HN wouldn't know what Waterloo was :). It even supports GO buses between Waterloo <-> GTA (unfortunate

Experienced this problem too in Toronto, when Google Maps wouldn't give transit + bike directions (which are often much faster than transit + walk). As you know the city more though these things become intuitive and Google Maps becomes

Wow, this website is very pretty. It's similar to what I envisioned when I built this project, but I wanted to make a heatmap (of all possible times) rather than just an isochrone. The little "islands" of fast transit access

Yes that's right. I do plan on adding other cities in the future, but these are the ones I've chosen because I've lived in them or I think they have a cool transit story.

Oops! I was only able to test it on my iphone and the devices in the Chrome browser simulator :(. If you're willing, what phone/browser are you using?

Yep the only cities that are supported are on the list at the top: Toronto, Montreal, Vancouver, New York, and Paris. Adding support for other cities is a pain in the butt to find the corresponding GTFS, upload the vector tiles to postgis,
