What's the difference between two_percent and skim?

What apps would you love to have open-source alternatives for?

It seems like the FOSS community is continuing to grow, and FOSS apps keep getting better (Immich reallh blew my mind recently), which is a big win 😎 but there are still many apps I use that I would kill for an open source alternative. I am curious what you guys think? Are there any apps you'd love alternatives for?

Check out https://novelwriter.io/

I'm not familiar with such softwares (I use pandoc for technical writing), but might help you..

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.

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 https://github.com/tombh/novim-mode!

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).

What open source programs do you recommend for Windows? (Windows exclusive or not)

I am and all my life have been a Linux user, I have nothing against Windows or MacOS, I just like Linux, and lately I have been experimenting with Windows in a virtual machine and I don’t really know much open source software there apart from the one that is cross-platform like Firefox or Joplin....

I have a book for Perl One-Liners as well, which I’m currently revising :)
