Owncast Stream whatever you want on your own platform and announce natively to the Fediverse!

IDK why but tons of folks think it's not feasible as they need million dollar computers. I've streamed to 70+ open streams, albeit as a test, on a like $5/month VPS. The key is that the resources needed are how many qualities you're transcoding, not how many folks are viewing. Yes bandwidth is needed for each viewer, but that's significantly less than people imagine.

Full transparency I run the [email protected] community, but I'm in no way affiliated with the project. I just love open platforms and open source.

Keepass/KeepssXC/KeepassDX (password manager for desktop)

Syncthing to synchronize database between devices.

For 3D Modelling / Printing, if you have even a little bit of programming / scripting ability, OpenSCAD is amazing.

It's basically just a small scripting language for generating 3D objects and performing 3D modelling operations and its so handy to be able to store important info as precise variables, and create new objects and cuts and stuff just with for loops and if statements.

I use the web version a lot of the time, and while it could use a little work, it's pretty amazing.

Darktable Great digital photography RAW editor. Alternative to Adobe Lightroom.

More people should code Csound. Doesn't matter if you're musically inclined or not. Just do it. Make weird noises. Have fun!

Kanipaan https://yu7.in/kani, a CLI calculator.

Floorp. It's open source fork of Firefox made by mostly Japanese developers. It's noticably faster, privacy focused than the original and have more customisation options.

I'm surprised it's not well known to be honest.

Ruffle: You may not know it but most old Flash games (and basically every anmiation) can be played again with this, modern and in a Browser sandbox. Website owners can include it in the backend with a few lines of code and all flash games work again automatically, and it's also available as desktop app :D
