• Obsidian - great markdown-based note app
• NewsFlash - fast and elegant RSS news reader
• Bottles - program to run Windows apps and managing them easily
• BreakTimer - a life-saver for me; it allows you to set a break after given amount of time
• LibreWolf - privacy-focused fork of Firefox

There are a lot of awesome programs on Linux, I recommend browsing Flathub to find them

• https://tilvids.com/c/johnny_marks_channel/videos?s=1 - Some video essays about movies and games
• https://fedi.video/c/lontv@peertube.lon.tv/videos?s=1 - It’s now abandoned but you can find some tech-related videos here

And like many people mentioned here, TLE, Veronica Explains and Tilvids are also worth recommending.
