The fact that the software being written in Rust is supposed to be valuable information to be put in the title is interesting. Nobody would say “Performant intracontinental public transport routing in C++”, or any other combination. It’s just something around the Rust language.

Turns out people do, actually: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

Obviously it's rarer with C++ than with Rust, but it happens in the same proportion with pretty much every language when its on a popularity boom (we've seen that with JavaScript a decade ago, then Go and python, now Rust).

Well, aside from the fact that people do say "in C++"... the fact that it is written in Rust is novel. Rust is still quite a lot less common than C++.

If you were reading an article about a concrete bridge you wouldn't expect "New bridge built out of concrete!" would you? But "New bridge built from 3D printed stainless steel!" is a perfectly reasonable title.

Why would you post this before checking?

Even without checking it makes sense to post "written in C++" (same as written in Rust).

I wonder if some people are lazy to think or just driven by emotions.

I think my info might be old then! I went and found where I learned that: https://discuss.graphhopper.com/t/does-graphhopper-gtfs-not-...

I may also be conflating inter-agency routing with ingestion of multiple feeds.
