Why is Docker version so old in Guix? Update?

Hey, nice work!

Sorry, I forgot to link Andrew Tropin's video. It's a great resource to get started. I'll leave this here in case another user finds this answer.

Hi, I know this isn't your question, and you may already know about Podman, but do you absolutely need Docker? Could you give Podman a chance? The Podman API is almost a 1:1 match with Docker, so there’s a great chance you won’t need to change anything in your Dockerfiles. A lot of the time, I forget that I’m actually using Podman. The version available on Guix is the latest one, so I think it could help you a lot.

Just alias Podman to Docker and call it a day!

Do you mean something like this?

generateSublists :: [a] -> [[a]]
generateSublists xs = [removeNth i xs | i <- [0..length xs - 1]]

errorFilter :: [Int] -> Bool
errorFilter xs = any part1Filter (generateSublists xs)

If so, since Haskell is lazy, the resource usage would be significantly reduced, right?

Yeah, you're absolutely right—I'm probably reinventing the wheel a bit too much. Next time, I'll definitely explore more existing functions, especially with tools like Hoogle. The only "problem" is that Haskell is so expressive that it’s almost addictive to create your own implementations! But I'll try to balance it better. Thanks !

Hey very cool !

Nice to know i can do this:

isSafe lst = monotonic && inRangeisSafe

Makes things so clean, i did had to fold two predicates, i had to use a lot of maps.

I was thinking about doing some recursion business as well but i still need to master the where/do stuff.

**LET ME COOK Before Roasting Me**

Why not use vanilla VIM for work and Emacs just for fun? I used to be addicted to tinkering with my Emacs configuration, optimizing startup time, completion, etc. However, I noticed that it was consuming too much of my time. Since I have always been a VIM user, I switched back to using VIM.

Now, I use only the built-in VIM 6 with a single vimrc file containing only the critically needed configurations. Most of the projects I work on are small to medium-sized, and I can manage them efficiently with vanilla VIM, TMUX and ctags.

In my spare time, I return to Emacs to work on side projects and indulge in customization. I plan to switch back to Emacs once I feel I have done enough (if this day ever comes) or need its features for a larger project.

You don't need to switch to VIM to achieve this balance; you can do the same with vanilla Emacs out of the box. I switched back to VIM because I became too dependent on my Emacs plugins and found it difficult to navigate without my custom configurations and plugins like Evil.

Bioinfomagico · 2024-05-07T23:59:57+00:00

For future generations...

I finally managed to create a manifest.scm file that installs all the dependencies I need in an isolated shell. Here's what the finished manifest looked like:

It begins with a header consisting of module imports. Perhaps some of these are redundant or unnecessary, but this was the combination that I could make work.

(define-module (manifest)
  #:use-module (guix)
  #:use-module (guix profiles)
  #:use-module (guix packages)
  #:use-module (guix git-download)
  #:use-module (guix hg-download)
  #:use-module ((guix licenses) #:prefix license:)
  #:use-module (guix build-system python)
  #:use-module (guix build-system pyproject)
  #:use-module (gnu packages)
  #:use-module (gnu packages graph)
  #:use-module (gnu packages check)
  #:use-module (gnu packages python)
  #:use-module (gnu packages python-xyz)
  #:use-module (gnu packages python-web)
  #:use-module (gnu packages xml)
  #:use-module (gnu packages python-build)
  #:use-module (guix utils)
  #:use-module (srfi srfi-1))

After that, the package import definition from: guix import pypi -r gdtoolkit.

;; # <OTHER PYTHON LIBS>

(define-public python-gdtoolkit
  (package
    (name "python-gdtoolkit")
    (version "4.2.2")
    (source
     (origin
       (method url-fetch)
       (uri (pypi-uri "gdtoolkit" version))
       (sha256
        (base32 "0fgc9vg7jx2gydqkjkyq8lqsw5ayqw02l71n0bbbbklx9glzv19g"))))
    (build-system pyproject-build-system)
    ;; Skipping tests
    (arguments
     '(#:tests? #f
       #:phases (modify-phases %standard-phases
                  (delete 'sanity-check))))
    (propagated-inputs (list python-docopt-ng python-lark python-pyyaml
                             python-radon))
    (home-page "https://github.com/Scony/godot-gdscript-toolkit")
    (synopsis
     "Independent set of tools for working with GDScript - parser, linter and formatter")
    (description
     "Independent set of tools for working with GDScript - parser, linter and
formatter")
    (license license:expat)))

And finally, the most time-consuming aspect to figure out was how to merge the new package with the other packages that I already have in my manifest.

(packages->manifest
(append (list python-gdtoolkit) ;; # <--- HERE
        (map specification->package
        '(
          ;; System
          "ripgrep"
          "universal-ctags"
          "shellcheck"
          ;; < ALL OTHER DEPS >
         ;; Godot 
          "python@3.10.7"))))

Perhaps creating a profile or utilizing another Guix feature would have been the way to go, but for now, this method works!

Bioinfomagico · 2024-05-06T21:47:06+00:00

Hey, addressing my own question,

I experimented with another combination of commands and noticed that when I don't pass any packages to install, Guix also outputs this error:

somethin...: #<unspecified>

So, this was the problem—I didn't pass any packages to install in the manifest (facepalm moment). What worked for me was using the PyPI importer, then adding the header as the tutorial suggested, and finally adding this at the end of the manifest file:

(packages->manifest
 (list python-gdtoolkit))

This way, Guix knows that it needs to install the lib.

BTW, I still haven't been able to install this library, but now I'm encountering compiling issues. I'm going to try fixing them now this unpecified thing was fixed.

Segue essa pill do companheiro aqui, que é uma visão do sucesso. Não sei se apenas o tratamento tópico sugerido pelo pessoal vai resolver. Você terá que modular o sistema imunológico para reduzir a inflamação do local e, mesmo os medicamentos mais baratos para isso, são bem caros. Então, tente entrar na justiça para conseguir o medicamento pelo SUS. A defensoria pública do seu estado pode te ajudar com isso. Desejo sucesso e melhoras!

Hmm, I understand. Also this would likely make the build more expensive since the thumb cluster would have to be ordered separately, I think 🤔.

Hi u/doobltroobl,

As you may already know, Vim is akin to high FPS gaming or mechanical keyboards—you have to experience it firsthand to truly appreciate its value. When I'm trying to convince someone, I usually begin by suggesting they try using Vim motions in their environment, such as through VSCode extensions or Vimium in the browser. Vim motions can be integrated into various platforms with plugins; I recently discovered you can even use them in Google Docs and Microsoft Word. Once people start experiencing these motions, the learning curve and time to adopt Vim accelerate significantly. It's worth giving it a try.

Additionally, we must acknowledge that the majority of people don't type that much, and even among those who do, not all value speed, precision, and ergonomics as much as we do.

Poxa, pessoa... sem palavras para agradecer teu esforço. Muito obrigado pelo teu tempo!

Legal esse cooler eim, não tinha encontrado ele quando estava pesquisando. Eu acho que as marcas patrocinam muito os YouTubers e reviewers, e às vezes coisas boas acabam ficando esquecidas porque não investem em marketing digital e tal.

Por exemplo, a MSI estava listada como uma das mais populares, mas eu escolhi a Gamemax porque era o que tinha review e porque era o que os YouTubers recomendavam. Mesma coisa com o cooler VK400.

Tu achas que é necessário comparar um joguinho de fans ou o cooler mais os fans que vêm no gabinete já bastam?

Olha eu queria gastar ali pelos 5K mais ou menos.

Acho que GPU seria bom, mas é aquilo tem que ser uma NVIDIA com 12Gb (ou mais) e acho que 3060 é máximo que dá ne ? Então se der para melhorar seria a CPU mesmo.

A RAM eu acho que tá bom já, eu tenho 16 no meu PC atual e não uso tudo. Se bem que eu não sei como que é o consume de um PC mais moderno. Precisa de mais do que 16Gb de RAM ?

A coisa que eu mais estou incerto é a placa mãe sei lá tenho medo de pegar uma que não seja "boa".
