I'm not the site author, just submitting the link.

Not sure which part you need to be logged in to view - I'm seeing links to different articles and exercises and they are all visible without logging (I checked in an incognito window).

oxipng, pngquant and svgcleaner for optimizing images

auto-editor for removing silent portions from video recordings

As per the manual, "Mappings are set up to work like most click-and-type editors" - which is best suited with GUI Vim.

While Vim doesn't make sense to use without the modes, there are plugins like https://github.com/tombh/novim-mode!

Bobiverse by Dennis E. Taylor is a fun and easy read

+1 for Cradle already mentioned. I'd add

• The Riyria Revelations by Michael J. Sullivan
• Kings of the Wyld by Nicholas Eames

I use GitHub pages and mdbook (https://github.com/rust-lang/mdBook)

EPUB reader

Hope you find the book useful :)

I'd also suggest these shorter guides to get started:

• https://ferd.ca/awk-in-20-minutes.html
• https://backreference.org/2010/02/10/idiomatic-awk/
• https://earthly.dev/blog/awk-examples/

See also:

• tldr — collection of community-maintained help pages for command-line tools
• explainshell — write down a command-line to see the help text that matches each argument
• General purpose command-line tools — examples for most common usecases
• Bash reference cheatsheet — nicely formatted and explained well
• Bash scripting cheatsheet — quick reference to getting started with Bash scripting

If you don't mind sci-fi: Red Rising by Pierce Brown

And there's the classic The Count of Monte Cristo by Alexandre Dumas

I start my search string with stackoverflow as a workaround.

Yeah, PCC is a good choice. Make sure to type examples codes manually (i.e. don't just read them) and try to solve all the exercises. Since you mention you want to learn it as a hobby, "Automate the Boring Stuff with Python" (2nd edition) would be a good choice as well, as you might find some of the projects in the second half helpful.
