  • TBH Rust is pretty nice, it borrows (pun intended) a lot of ideas from the functional world (algebraic data types, traits, closures, affine types to an extent, composition over inheritance, and the general vibe of type-driven development), but it’s much easier to write fast, efficient code, integrate with decades of libraries in imperative languages, and the ecosystem somehow feels mature already.


  • So, here’s my attempt

    The first portion (^.?$) matches all lines of 0 or 1 characters.

    The second portion (^(..+?)\1+$) is more complicated:

    1. (..+?) is a capture group that matches the first character in any line, followed by a smallest possible non-zero number of characters such that (2) still matches (note that the minimum length of this match is 2)
    2. \1+ matches as many as possible (and more than 0) repeats of the (1) group

    I think what this does is match any line consisting of a single character with the length

    • divisible by some number (due to the more than 0 condition in (2), so that there have to be repeats in the string), that’s not
      • 1 (due to the note in (1), so that the repeating portion has to be at least 2 characters long), or
      • the length itself (due to the more than 0 condition in the (2), so that there is at least one repetition)

    Therefore, combined with the first portion, it matches all lines of the same character whose lengths are composite (non-prime) numbers? (it will also match any line of length 1, and all lines consisting of the same string repeated more than one time)


  • 90s-late 00s cars are actually on repairability in my experience, because they already have computers which help you diagnose failures easily with a $20 OBD2 scanner (this saved my ass a couple of times, when I could almost immediately see the error whenever my car died, fiddle or re-plug the wiring of the failed component and keep going), and they don’t yet have all the over-complicated, designed-to-fail, hard-to-reach crap that a lot of new cars have.

    Hey, you can add the satellite imagery you need by doing Configure Map > Underlay > Underlay map > Add more. Then you can select the imagery you just added from that same menu.

    After you’ve selected the underlay map, you can pre-download the images for offline use by viewing the part of the map you want to download, touching&holding anywhere on it, then doing Actions > Download Map.

    Hope that helps.




  • “NixOS project” did not call anyone nazis, there was no “purge”, this article is clickbait and ragebait. What one contributor, however prolific, says, doesn’t represent the entire project (even though I somewhat agree with him here - there are sadly some bigots in the community).

    Nobody forced Eelco (the founder of Nix) to “abdicate”, but there was indeed pressure to step down as the de-facto BDFL put on him by various people. He’s respected as an engineer, architect, maintainer and mentor, but his community management skills were perceived to be lacking, and there were other perceived issues in the community - which boiled down to the fact that a lot of contributors didn’t feel like they could influence the direction of the project. Note that he’s not expelled from the project in any way, he’s still a maintainer of Nix itself, which AFAIU from my interactions with him is what interests him the most, and he’s more or less happy to leave administrative/community stuff to other people.

    Then began a process to establish a new governance structure. Currently, we’re up to a stage where there’s now formal community values and a new constitution for the project. There’s an election happening right now, with all active contributors able to become candidates or vote (although the deadline for candidate nominations has passed, so now we can only vote).





  • UNIX was kinda designed to be an IDE (of its time) by itself. Desktop/Server Linux (whether GNU or non-GNU) mostly continues this tradition; you are provided with some powerful tools for text manipulation, development, debugging and deployment out of the box in most distros. As such, any modern Linux distro is pretty good for development even out of the box. However, you must learn to use this power, and I’m not claiming it’s easy (I still regularly look up various manpages despite doing development on Linux for 10+ years in various forms).

    With that said, I myself prefer NixOS. It really feels more developer-oriented that other distros, as you get the power of Nix out of the box, and integrated into the system. With Nix you get easy access to the biggest software repository in the world. You get per-project development shells, so that you never have to worry about different toolchain versions for different projects, or your system being contaminated with bloat you no longer need. You get the power of reproducible packaging, to eliminate a lot of (but unfortunately not all of) “Works on my machine”-type of problems. It’s also got a hell of a learning curve, but I think it’s worth it.

    My understanding is that the Congress of Soviets was replaced with the Supreme Soviet, the democratic structure was changed but the Soviets remained, just shifted in form, and could still be used democratically, just not in all cases.

    I believe this is true, but I would argue that the fundamental change was that non-Party candidates were almost never allowed to run. As I noted, this is not due to a constitutional change but rather a change in electoral tradition. Anecdotally, as a result of this, all three my grandparents didn’t feel represented by their deputies/delegates, and welcomed that part of the Perestroyka changes, when the rules were relaxed and more alternative candidates appeared.

    A good analogy is that most local governments in the US run uncontested.

    I believe this to also be a non-ideal situation (especially given the two-party system where neither represents the working class). However, aren’t there at least party primaries, so that one can choose which candidate from the dominant party “runs” for the uncontested election? Whereas in USSR the candidates were chosen by the Party and not the electorate directly. (my understanding of the US electoral system is lacking, so I may be wrong here).

    That’s why I stressed reading Blackshirts and Reds, which dispels the mythology and takes a critical, nuances look at the USSR.

    Thanks for the recommendation! I’ve started to read it a while ago, and mostly agreed with the contents. I’ll have to pick it up again.
