Do you have any advice or suggestions about it?

• Hardware (what should be enough for a local PC, or VPS...)
• Software (OS [Debian, Yunohost, other...], "containerization" (Docker, virtual machines?), dashboard, management, backups, VPN tunneling...)
• "Utilities" to host (Lemmy, Peertube, Matrix, Mastodon, Actual Budget, Jellyfin, Forgejo, Invidious/Piped, local Pi-Hole, email, dedicated videogame servers like for Minecraft, SearXNG, personal file storage like Drive, AI [in the future, when I can afford a rig that can run a local model decently]...)

I'm aware it's a lot of stuff to take on, so, do you have any advice on where to start? (how to find a cheap PC to experiment with, if not get a VPS, what to test on it, what "utilities" to try self-hosting first...)

I have seen several people saying the order operation is

• Brackets/Parenthesis
• Orders (roots and powers)
• Divisions
• Multiplications
• Subtractions
• Additions

But I was taught it as

• Brackets/Parenthesis
• Roots and powers, left to right (independently of the exact operation)
• Divisions and multiplications, left to right (independently of the exact operation)
• Subtractions and additions, left to right (independently of the exact operation)

So, what order were you taught and/or use today?

Hello,

I have been thinking about making the jump towards Open Source, not just using OSS but also contributing to it.

First, some OSS projects/apps I know of are Peertube, Lemmy (right now using Voyager app), Mastodon, Matrix (used to use the Element app, gave up because I realized it was too hard for those around me who got used to Whatsapp), OpenStreetMap (through OrganicMaps), Jellyfin, and Actual Budget, Godot Engine, Luanti, GrapheneOS... I might know more, but those are the ones I remember right now.

Second, I have some basic experience with programming (mainly Java [haven't learnt GUI yet tho], SQL, and C# for Unity videogames), but no experience entering an already created codebase yet, let alone making changes and sending them (and I admit I might need to get some practice with Git), so it is pretty intimidating. Do you have any advice about it?

Third, I'd like to hear about projects you find interesting or useful. Not neccesarily to contribute or even use them myself, but I'm interested in which other projects there are out there.

Edit: Thank you for the responses, what I got was basically find OSS to replace not-OSS I currently use, and contribute either fixing issues myself, helping with other stuff (making issues, writting or translating documentation, helping newer users), or giving feedback on the project.
