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 …

There is a virus written in awk that infects other awk scripts[0]. And according to wikipedia, the language is Turing complete. [0]: https://github.com/SPTHvx/ezines/tree/main/dc5/…

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…

Could you give some links or pointers (which city/building/year)? I know of the band but not that story.

Sounds like a botnet with extra steps

The linked paper is not my thesis but one of the foundational works, I based my thesis on. Mine can be found here: https://git.vbrandl.net/vbrandl/masterthesis/raw/branch/mast...

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 monito…

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. Thi…

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 "…

Maybe cargo2nix? https://github.com/cargo2nix/cargo2nix

In the end you could use nix to build docker/VM images and use the same, reproducible environment in prod/test/CI/dev/...

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 projec…

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 al…

Private feedback via email is always possible and you can chose to publish specific feedback you deem important. It's the same for printed literature. There is no comment section i…

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 (…

Fear and Loathing in Las Vegas, by Hunter Thompson if anyone is wondering

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…

If the vessel was started at day, the earth was also pushed away from the sun

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

Option , 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.…

I think that's intentional and meant as an example of the issue at hand.

FYI: > a meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular …

Best would actually be #!/usr/bin/env sh Since this binary is required by the POSIX standard to exist at that location.
