I have recently created a tech feed site covering over 1500 RSS/Atom feeds. I have promised to make the complete list available and have created now a Codeberg Repo with all the feeds.

If you want browse the articles, you can visit: https://insidestack.it/

Or if you want to read articles organised by topics, you can visit on of the spaces. Like for Linux: https://insidestack.it/spaces/linux

All spaces have their own RSS feeds which you can follow.
