Show HN: CLI text processing with GNU sed (eBook)
Hello!
I am pleased to announce a new version of my "CLI text processing with GNU sed" ebook. This book heavily leans on examples to present features one by one. In addition to sed commands and options, regular expressions are also discussed in detail.
Links:
* PDF/EPUB versions: https://learnbyexample.gumroad.com/l/gnu_sed (free for a few days)
* Web version: https://learnbyexample.github.io/learn_gnused/ (always free)
* Markdown source, example files, etc: https://github.com/learnbyexample/learn_gnused
* Interactive TUI app for exercises: https://github.com/learnbyexample/TUI-apps/blob/main/SedExercises
I would highly appreciate it if you'd let me know how you felt about this book. It could be anything from a simple thank you, pointing out a typo, mistakes in code snippets, which aspects of the book worked for you (or didn't!) and so on. Reader feedback is essential and especially so for self-published authors.
Happy learning :)

Useful sed scripts and patterns for day to day usage
Many commands using `-r` do not need the option for the command used (for ex: `sed -r '/start/q'`). Also, using `-E` is preferred instead of `-r` since some of the other implementations support this option but not `-r`.

I wrote a book on GNU sed with plenty of examples and exercises: https://github.com/learnbyexample/learn_gnused It is free to read online and there's a detailed chapter for learning BRE/ERE regex flavor as well.

Linux/BSD command line wizardry: Learn to think in sed, Awk, and grep
Good introduction. But they should've at least mentioned that these tools can read a file input directly.
>For example, the sed man page weighs in at around 1,800 words alone without ever really explaining how regular expressions work or the most common uses of sed itself.
For Linux versions, `info` pages for grep/sed/awk are much more detailed and includes examples too. I use `man` pages only for quick reference. Also, I think I've read that BSD man pages are more detailed and include examples compared to Linux versions.
If you'd like to learn more, I have books on these commands with hundreds of examples and exercises (free to read online):
* https://learnbyexample.github.io/learn_gnugrep_ripgrep/
* https://learnbyexample.github.io/learn_gnused/
* https://learnbyexample.github.io/learn_gnuawk/

Bountysource Stole at Least $17,000 from Open Source Developers
There's fraud and embezzlement in non-profits all the time. Just entering that in a search engine shows tons of examples: https://duckduckgo.com/?t=ffab&q=fraud+and+embezzlement+in+n...
When I was involved in scouts this was a thing as well; not even always due to malice, sometimes also due to incompetence and/or inattention.

Microsoft killed my favorite keyboard
that one is good, but I detest keyboards with their own magic little dongle since it's a damn fine thing to misplace
I'm surprised OP didn't enjoy https://www.microsoft.com/en-us/d/surface-ergonomic-keyboard... which is currently listed as out of stock but I dunno if that means "permanently" or what, but they seem to be available via 3rd party channels
Its "klacking" aside, pour one out for https://duckduckgo.com/?q=microsoft+natural+elite+keyboard&t... which I loved, although I'll be straight that I love the Surface Ergonomic better because I think its keytravel is much, much nicer and no weirdo + shaped cursor keys, the inverted T like $diety intended

Ask HN: Where are all the touch-based art forms?
Sculpture can be tactile. I know it's not purely tactile, but thinking of it in that way is becoming a lot more common (eg at the Louvre). And then I went to find a URL for the tactile dome at the Exploratorium in San Francisco (https://www.exploratorium.edu/visit/tactile-dome) and it turns out there are lots of tactile galleries now:
