  • I didn’t see this mentioned yet, but IP ranges are normally assigned by generic location, so each of thes routers routing to the next one (hops) basically have a memory table from prior routes/configured by ISPs to say “this is the best current upstream router to route to for this destination”. They also store the distance between routers and aim for the smallest distance. this is how they are fast and is called routing tables.

    Routing tables can be misconfigured causing major outages and old routers used to be able to only store a smaller table so 512k day happened. We already passed the next one 768k though ISPs mostly had their crap together for that one.










  • Flakes is a way to manage nix, nix is essentially a package manager, NixOS would be probably easiest way to play with these tools.

    You define a flake / nix configuration and they are designed to be installable on any system. Think of it as if you install and configure all of your programs, services, environment in it and you upgrade to a new PC, you run a command to install your flake from your previous PC and everything is configured how you had it on your previous PC.

    Flakes is a new tool and is under rapid development, so it may have breaking changes in the future, but it is so popular that the devs are trying not to break it as much as possible.

    Also take my comment as a grain of salt since while I know about flakes and use it, I am nowhere close to an expert on it and terms that I used may be incorrect especially for defining them, but in layman’s terms I think its a decent introduction to what it is.

    And America has had a huge problem getting new truckers gee I wonder why? Their solution is to reduce education and throw more new truckers on the road. “Pay by the mile” sounds like a huge safety issue too, stressing about being as fast as possible and not stopping or slowing down for anything as a cautious driver would sounds like a recipe for disaster.
