I would guess OSM uses optimizations for eucledian graphs, where the path a->c is always shorter than a->b->c. This restriction makes e.g. TSP solvable. But this property does not hold for any generic graph. I don't know if th

That's the point of EurKey. Special characters are the same as on the US layout with additional, language specific letters available. At least for writing English and German it has been great for me.

PageRank and similar ranking algorithms on graphs can be used to detect monitoring attempts in P2P botnets [0] (a botmaster can detect when researchers/law enforcement start monitoring a botnet). For my master's thesis, I evaluate

Maybe I did not use it as intended, but I have an app running on fly.io that exposed the metrics endpoint on another port as the webapp itself, so it is not publicly reachable. This app suddenly broke and I had to disable the metrics endpoi

Since I have no use for it, I like to globally (not just in vim) map caps to ESC.

I also applaud their user-respecting design choices. E.g. if your browser sets the DNT (do not track) header, they won't show a cookie consent banner and just assume you selected "reject all"

One thing that differentiates nix from things like virtualenv is that each (package + version) tuple exists at most once in your local nix store and is then linked into your project environments, while virtualenv will install new copies of

If you are looking for a language agnostic version manager, the nix package manager [0] might be worth a try. In combination with lorri [1] you will be dropped into a shell with all required development dependencies available, when you ente

I learned typing on German QWERTZ, too. I started using eurkey [0] a few years ago. For me it hits the sweet spot between good position of special characters used for programming (it's effectively QWERTY in that regard) but with common

Maybe by releasing often (every 6 weeks or out of band for bug fixes like this), they make it easier to use a current version of the compiler, in comparison to the old Java release cycle of multiple years. Also testing the compiler against

~I'm not sure about the semantics, but the type would allow that, yes.~ Edit: fn scatter(&self, ray: &Ray, hit_record: &HitRecord) -> Option<(Option<Ray>, Srgb)> The function takes a `Ray` as input,

Option<(Option<Ray>, Srgb)> can be one of - None - Some((None, Srgb)) - Some((Some(Ray), Srgb)) Only the last one is equivalent to the struct you described

Here is a small back of the envelope calculation. Websters dictionary includes 470.000 words [0]. 52 lower and uppercase letters + 10 digits + ~20 special chars = 82 possibilities. There are are 82^20 = 1.89 * 10^38 possible combinations fo
