You should try installing vim (“Vi IMproved”) and run the vimtutor program it comes with, it walks you through the basics. Vim is addictive.

I agree that was inappropriate, but it won’t work, on newer versions you have to pass --no-preserve-root to rm if you want to delete /

Of those I subscribe to, a few I don’t miss reading:

• https://www.the-syllabus.com/ - A curated selection of articles and videos. Broad, it covers politics, tech, etc through careful journalism, papers and talks.
• https://www.aisnakeoil.com/ - Commentary and chapters from a forthcoming textbook. Tired of all the lazy hype so this is nice to read. By Arvind Narayanan (the PL researcher) and an AI PhD student.
• https://www.carbonbrief.org/ - Weekly summary of climate stuff, something important but Im too lazy to properly follow news.
