I attended the dry-run of this course* recently and it was pretty mind-blowing - I'd seen before how #pixi can be used for python packaging but this course introduced me to a few new example use cases:

- Reproducible data analysis in #R
- A new application in #C
-Image processing with #Python
- #Jupyter Notebook for exploratory analysis

C 언어 개발자들이 사용하는 정적/동적 라이브러리를 C#으로 만들어 제공하는 시대가 왔습니다. 다만 짚고 넘어가야 할 두 가지 키 포인트가 있어 제가 알게된 내용을 공유드려봅니다.

C/C++을 개발하시는 분들과 사이좋게 강력한 기능을 나눠가지며 더욱 뛰어난 생산성을 보여주는 소프트웨어가 앞으로 더 많아지길 기대해봅니다. 물론 시행 착오는 있을 수 있겠지만 계속 발전할 수 있는 영역이라 믿어 의심치 않습니다. :-D

foreign-dlopen: call dlopen from static programs https://lobste.rs/s/feeb0w #c
https://github.com/pfalcon/foreign-dlopen/

a bit of #rant I guess (?)

So the state of the #ui in today world is that apps care more about the "brand" instead of using darn OS widgets (so all apps would look more or less uniform with the platform). Turns out that #Qt kinda switched from QtWidgets (native OS controlls) to QML and Qt Quick which doesn't use native widgets but rather paints it's own that try to look like the native ones via theming. So if you want native you should use QtWidgets.

Qt is kinda huge though because it's not only UI but a lot of libraries as well…

On the other hand there is a #libui (https://github.com/libui-ng/libui-ng) which seems great (and has neat bindings for #Rust) but it lacks quite a lot of widgets… (and on Linux they only do GTK :/)

Would be nice to have something like scaled-down-QtWidgets that don't require "whole" Qt and would offer nice bindings to Rust…

(though yesterday I dabbed a bit in "modern" #C++ and it wasn't all that terrible 😱 )

Sometimes old projects are back. Made some updates for my utility, which is used to control brightness of a display, connected to the #Thinkpad X220/X230 via the AGAN X230 board (from AliExpress):

- Since I'm using Awesome WM and don't want to write a logic to change brightness on the Lua, I added the --increase-brightness / --decrease-brightness options to change it by one step.

- Add option --percent to display current brightness level not as internal value from board, but as percentage.

- Update man page, add ChangeLog.

For now it is tested under #FreeBSD 14.1-14.3.

@giacomoGiacomo Tesio @natecox @FionaFiona Wonder what old languages you have in mind.

On my ground if someone wrote #C++ in 2011 standard and I need to use #C++ in 2023 standard I really find such libraries outdated where for example arguments aren't `std::string_view`. They scream for update.

4 years using and championing the #fediverse full time and I've never written a #introductions toot. Well, or I have and can't find it.

I'm a #blind guy from 🇬🇧 with a passion for #technology and #programming, particularly #lowLevel #systemsProgramming in #C, #C++, #Rust, etc.

I've been a huge #freeSoftware / #openSource advocate for the majority of my life. I run #Linux and I love open, #decentralised technologies like #ActivityPub, #Matrix, #bitTorrent etc.

In my view, technology is built to make our lives easier, and in many ways, it isn't these days. It is truly my opinion that the only way #tech can be sustainable is if it's built using #FOSS, and does not give ultimate control to any 1 entity, individual or corporate. If technology is to help the people, it must be built *for* the people.
