Discover Hidden Gems: Open-Source Software You Should Know About
-
LocalSend should be called God Send because it'll save your life. It's AirDrop, but for everything and open source. Works really well, no setup, no server.
Unfortunately, its not reliable. For large media files it gets stuck. Also, sometimes the local server is not discoverable on the other end. Even though I tried the troubleshooting step.
I had tested with windows and android so it could be different on Linux.

wrote last edited by [email protected]I think android HealthConnect doesn't get enough notice as it is a kind of silent background service.
It is local, opt-in, and privacy respecting connection API for sharing data between fitness apps with fine control over what gets shared where. You can have the shittiest privacy-violating fitness app and it can't just steal all of the data from your smartwatch or whatever because you connect the two apps via a stupid cloud integration.

Ooh, that looks polished, I’ll have to look into i- why is hiccup from how to train your dragon there

This might read as a stupid question but ; Do you have to use KDE Plasma as a DE for it to work ?
No, it works on other setups too! I have used the regular kde connect app with enlightenment DE for example.

Open source though?

Sounds nice, for which services do you use it?
I've had mixed experiences with Invidious but haven't tried that for some time.
wrote last edited by [email protected]Not original comment but I use it to not directly go to Twitter, Reddit, and sometimes YouTube (ReVanced or FreeTube for me). They have a shit ton of services that can be redirected, although you have to worry about the proxies that are dead (Instagram, Tiktok). Even then, you can use it to avoid directly visiting the real site if you miss-clicked.

Copyparty turns almost any device into a file server with resumable uploads/downloads using any web browser
Reading that readme was nuts. Others can start downloading your upload before you finish uploading as well, which probably makes for some novel real-time use cases.

Looks awesome. Gonna try it out.

FindMyDevice, a find my server with channels through sms, a self hostable server, notifications. This is one of my favorite android utilities.
A search came back with many different results. Link?

KDE Connect: An app for iOS, android, pretty much every flavor of linux, windows, etc. that lets you connect any devices together to share files, show notifications of other devices, use your phone as an input device(keyboard, mouse), control multimedia applications(start, play, stop, etc.), trigger commands, and everything else if you make a plugin for it.
The craziest thing I discovered when I started using it was when I noticed that because my desktop was now connected to my phone and my phone was connected to my watch, I could completely control the media on both from my watch and the integration felt natural - but also something I haven't seen work that well in the proprietary world.

Lichess: A popular free, open-source online chess platform offering play, puzzles, and tournaments.
Yea, when chess.com started limiting engine analyses to 1 per day I jumped ship to lichess and never looked back.

The gods of learning and studying with flashcards. You will never want another flashcard program, especially if you were still using Quizlet (so enshittified now...) because Anki uses SRS (spaced repetition system) which makes you review things right before your brain forgets it to reinforce the subject material.
Add-ons: Bread and butter of Anki, I use several to make beautiful automatic flashcards of reading material/videos/games when I study Japanese. There's an add-on for literally anything.
Cross platform: Free on desktop, cost $25 on iOS, and free on Android, although Ankidroid is an unofficial app. Still great though!
Cloud: Syncs your anki database across devices. If you don't use anki for a while, will delete from the cloud, but as long as you have your own local database intact, you can reupload again later.
Sharing Decks: If you don't feel like making your own decks, download ones that others shared for free.
Anki is used by language learners, college students, med students, etc. If you need to memorize it, use Anki.

My only complaint with KeePass is that if any corruption occurs, your passwords are borked. I use KeePass for non-critical accounts, like Lemmy, etc. I don't trust myself or the sync enough for storing my bank or other identity passwords.
KeePassXC can automatically keep a backup when it makes changes.

Lichess got me back into chess after many years.
