    Project mention: Ask HN: What are some unpopular technologies you wish people knew more about? | | 2023-12-02

    (1) Zulip Chat - - seems to be reasonably popular, but more people should know about it

    I’ve been using it for over 5 years now [1], and it’s as good as ever. It’s way faster than any other chat app I’ve used. It has a good UI and conversation model. It has a simple and functional API that lets me curl threads and write blog posts based on them.

    (only problem is that I Ctrl-+ in my browser to make the font bigger – I think it’s too dense for most people)

    (2) re2c regex to state machine compiler -

    A gem from the 90’s, which people have done a great job maintaining and improving (getting Go and Rust target support in the last few years). I started using it in 2016, and used for a new program a few months ago. I came to the conclusion that it should have been built into C, because C has shitty string processing – and Ken Thompson both invented C AND brought regular languages to computing !!

    In comparison, treesitter lexers are very low level, fiddly, and error prone. I recently saw dozens of ad hoc fixes to the tree-sitter-bash lexer, which is unsurprising if you look at the structure of the code (manually crawling through backslashes and braces in C).

    These fixes are definitely appreciated, but I think it indicates a problem with the model itself.

    Project mention: Roundcube Open-Source Webmail Software Merges with Nextcloud | | 2023-11-29

    I have good news for you:

    Nextcloud is nothing more than a collection of small apps. You can disable even core things like sharing.
