Is it regex or sed/awk syntax (or both) that gives you trouble?

I had similar reaction and didn’t even try to learn them for years - then I caught the stackoverflow craze of answering CLI questions (and learning from others).

Not my blog, just sharing it here. Saw it on HN (news.ycombinator.com/item?id=40419325)

What’s the difference between two_percent and skim?

learnbyexample OP , 2 months ago

I’m self-published and haven’t worked for other publications. Sometimes, my submissions reach HN front page, so you might have seen there or because others picked it up from there and shared around elsewhere.

You’re welcome, happy learning :)

Yeah, it is uncommon spelling, but if you google, you’ll find it’s not that rare ;)

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 github.com/tombh/novim-mode!

Thanks! 😊

Thanks a lot for the kind words! Means a lot to me :)

I had to learn Linux CLI tools, Vim and Perl at my very first job. Have a soft spot for Perl, despite not using it much these days other than occasional one-liners (mainly for advanced regex features).

I’m doing a beta-read. Well written, great ideas, etc. Unfortunately, the book is turning out to be much darker than I’m comfortable with. I’ll probably try to get to the halfway point before deciding to give up.

Like alpha, beta, gamma readers. Used by authors to get feedback at various stages of their book before it is published. Alpha stage is very rough, like first draft. Not sure where the line lies between beta and gamma stage, but they are close to finished works - only typos and minor changes would be made based on reader feedback.

For indie authors, beta readers often help to get a few reviews out close to book publication.

I’m a bit active on book-related forums. I post reviews of books I’ve read, give book recommendations, etc. In this case, the author contacted me based on my reviews.

+1 for Murderbot!

Stormlight Archives can be daunting to those not familiar with Sanderson’s works, especially since the books are long (1000+ pages) and the first book is setting up a long 10-book series (plus other stuff from a wider universe).

If you’d like something smaller and standalone to try first, check out “Emperor’s Soul” (novella) or Warbreaker (novel).

Hopefully less than this year. I’m reading too many (100+) and that’s reflecting in my reduced time on actual work (self-employed).

I mostly read fantasy and sci-fi, which tend to have multiple books in a series. If they are easy-to-read and short (300-400 pages per book), it becomes easy to consume. Also, I read for escapism, so I don’t read too closely.

When I was younger, I’d read slowly, trying to visualize the setting, keep track of character preferences, look up words I don’t know, etc. I’d remember a book well enough to talk about it even a year or so after.

These days, I just skim over descriptions and read as fast as I could while still getting the main plot. I get attached to characters only if the book is really good and savor them during rereads.

True, perhaps a case of doing too much of anything over a long period ;)

+1 for Cradle already mentioned. I’d add

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