How and where can I look for various open source projects (preferably in Russian)?

Question

open source

I would like to program "for myself" in my free time. It seemed logical for this to participate in an open source project.
I would like to choose an interesting (for me personally) and Russian-language project.
Where can you look for them?
And the question after that, how to start participating in an open source project, if your understanding of development is at the level of a green junior?
PS: language is not particularly important. preference in descending order: C#, Java, C++ (Qt)

Answer 1

Search GitHub for PLs/technologies in which you want to develop.
Start with translating/writing documentation, checking bugs, etc. You can also search for projects that lack contributors.
I would not advise getting hung up on Russian-language projects, the open source language is English, even Russian developers usually lead projects in English.

Answer 2

If you still don't know exactly what you want, then look at SourceForge - one of the largest platforms for open source projects. There is a convenient cataloger for programming languages, target operating systems, project development stages, etc.

Answer 3

Take an early beta version of your favorite framework and write a small application on it.
All the glitches that you find - fix it yourself and put it in the issues of the project.
Read other issues and fix bugs in them.
Congratulations! You are a true open source dev.
