  • If I’m honest it’s breathtakingly beautiful. I’ve been around most of Europe and some of Asia, and the only comparable places are Swiss Alps and the Himalayas; however, Georgia is much cheaper than the former and more developed/safe than the latter. It’s also quite tiny but heterogeneous: within a day’s drive you can go from (slightly underwhelming) Black Sea through amazing forests into wild mountains, back down to vineyards and sunflower fields, through a volcanic plateau with otherworldly landscapes and then bathe in hot springs under the starry sky. There’s an insane density of buildings and ruins from dozens of different cultures and epochs, all the way from bronze age to medieval Georgian to Russian colonial style to Soviet-era constructivism. I don’t drink wine but I’ve heard that it’s quite amazing too. My only gripes is that the country might be backsliding into authoritarian rule, and the locals are welcoming but “conservative” (bigoted) to the extent that it’s straight up dangerous for LGBT people to visit.


  • Back when I was in Russia I’d say it’d be Suzdal, famous for the density of churches and other traditional architecture; or Tarusa, known for that one song that everyone seems to know a couple of lines from, Gorodok (here is a random rendition I found just now), both with just under 10k pop according to the wiki. And, as a bit of a stretch since it’s not a town and most people would call it Solovki, Solovetsky settlement, famous for being a prison, with about 800 people. Also Oymyakon with under 600 people, the coldest settlement on earth if you’re into that sort of thing.

    Now in Georgia, I’d say Borjomi with just over 10k pop famous for its water, and Bakuriani (just over 1800 people) for its water and the ski resort. Again a bit of a stretch, but I guess everyone in Georgia at least also knows the ski resort of Gudauri at just under 100 people, as well as mountain resorts of Gomismta and Bakhmaro, both with no permanent residents due to the rough winters. Geography nerds will also be familiar with Ushguli, (arguably) the highest inhabited settlement in Europe, population 220.


  • Typically this is true, but it’s certainly possible to get comparable performance with functional style

    It’s possible, but you have to specifically write code that’s fast, rather than idiomatic or ergonomic, and you have to know what you’re doing. At that point, you may have been better off writing it in something else. I feel like OCaml is good at this because it allows you to write abstractions and main control flow in a functional way and hot paths in an imperative way without switching language, but so is Rust.

    Carp, which I linked above, basically uses the same approach to memory management as Rust. It doesn’t rely on GC.

    I’ll take a look, thanks!

    I also find that for most cases it really doesn’t matter all that much unless you’re in a specific domain like writing drivers, making a game engine, etc. Computers are plenty fast nowadays, and ergonomics tend to be more important than raw performance.

    I mostly agree with you, e.g. Haskell and Clojure, despite being “slow”, are plenty fast for what they’re used for. On the other hand, I’m very much annoyed when “user-facing” software takes way too long to load or do simple tasks. Java in particular is pretty bad at this: JOSM (Java OpenStreetMap editor) takes longer to load than my entire desktop startup, including a window manager and browser. Unfortunately it’s also the best editor around, so I pretty much have to use it to edit OSM, but it still annoys me to no end. Unnecessary computations, IO inefficiencies and layers of wrapping also affect the power consumption quite noticeably.

    Modern C compilers are a fascinating blend of functional and imperative, that’s true; and I didn’t say that C is “close to how the modern architectures work”. However, mainstream modern architectures are almost always engineered with C in mind primarily, and this is also acknowledged in the article you’ve linked. Rust, having a lot of similarities to C in terms of its underlying memory model, calling conventions, and control flow primitives, can often benefit from those hardware patterns and optimizations in a way that’s more difficult to replicate with a functional language (especially so given most of them are GC-d due to their memory model). The closest I’ve seen in terms of easy-to-write-quick-code is OCaml, but even there the fast paths are often written in a very much imperative style. Idris2 also seems promising if they manage to get a GC-less mode working. Maybe also Roc, but I’ve not taken a look at it yet.

    Note that I write all of this as someone spending a lot of their work time programming in a functional language (Haskell), with Rust being mostly for hobby stuff. It just always surprises me how much easier it is to write fast code in Rust, and yet also how much of my Haskell intuition was applicable when I was learning it.


  • I agree that they fit different niches! My point was that with modern CPU architectures, imperative languages make it much easier to write fast&efficient code just because the hardware was pretty much engineered with C in mind. IMHO Rust offers the best of both worlds when it comes to systems/low-level dev.


  • 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)






  • “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.

    Soviets were de-facto abolished after 1936 (not due to the constitution itself, rather “by tradition”). While there technically were elections, in almost all cases there was only one candidate. The three of my grandparents that I grew up with (all proudly working-class - teacher, engineer and doctor, born in 1930s), never participated in elections with more than one candidate until Perestroyka (at which point the communist project was on its deathbed).

    Note that I’m not even anti-USSR, it’s still markedly better than the bullshit capitalist systems. There actually was plenty of workspace democracy, and some local democracy, but I don’t think we should glorify it as some bastion of democracy. There still unfortunately was a kind of ruling class - the Party and MGB/KGB (but I should note that it was much easier for a working-class person to join their ranks than it is in capitalist “democracies”). Rather, learn from what it got right, and fix what it got wrong.


  • Problem is not how weak or strong the encryption is

    Here it’s definitely part of discussion. The context was

    It’s encrypted anonymous communication capabilities.

    It’s barely anonymous, and poorly encrypted. The latter is the reason Durov is in custody while Signal devs are scott free. He could easily turn illegal stuff over to French authorities, but doesn’t.

    The bigger problem is that people somehow assume this a huge threat, while all previous cases didn’t involve anything like that.

    There have absolutely been cases where a backdoor/weakness/lack of encryption used to catch criminals before: https://en.wikipedia.org/wiki/Operation_Trojan_Shield https://en.wikipedia.org/wiki/Ennetcom https://en.wikipedia.org/wiki/EncroChat . I distinctly remember that there were also arrests of opposition activists in Russia based on personal messages in VKontakte, but can’t find the news right now.

    real criminals do their stuff everywhere (especially on telegram) for years, staying safe.

    Some are staying safe, others are being caught precisely because of this.

    Problem is not how weak or strong the encryption is, but that once you are under oppression and do opposition activities, you’re going to learn by yourself how to deal with it.

    Using better encryption schemes is definitely part of that.


  • Toy may call it TLS but it’s a custom protocol.

    Sure, it’s mtproto. The security it provides for non-encrypted chats (which are the absolute majority of chats) is not any different from just having TLS for transport. It’s potentially even worse as it’s not as well-audited.

    Data is not kept unencrypted on their servers, according to their docs.

    That just means that they store both your data in some encrypted way and the key. They can still read it trivially. You don’t even have to know the protocol to understand why: you can add new devices without having any other device online, and read all non-secret chats. It might also just mean disk encryption, in which case it’s plain-text in RAM while the server is running.
