The full book online, and perhaps the best resource to learn Haskell.

If you know some programming but not functional or haskell programming, this should be the right resource.

Learn SQL. Interactive 'book', light-weight and intends to be the 'best place on the internet for learning SQL'.

Looks awesome to learn!

Grab data from websites (for now: has pre-made importers for Shaarli and Github Awesome- lists but can create your own), and do stuff with them.

Uses a variety of processors and exporters to shape, fix and transform the imported stuff. All based on yml 'pipeline' specifications. Essentially, it's a bit like setting up github actions/woodpecker CI for arbitrary pages.

Self-hosted bookmark manager that is designed be to be minimal, fast, and easy to set up using Docker.

Like shaarli, little different interface but mostly same feature set.

Not sure if you can make your whole bookmark list public or just share individual bookmarks.

The most interesting thing for me is probably its internet archive integration - when you bookmark something it automatically sends to and processes on IA, meaning you always have a snapshot of the exact state you saved it in.

Forked from barrier (itself forked from synergy) for multi-pc control by letting you seamlessly move mouse/keyboard between systems.

Using altair to visualize data, a book by jjallaire. Nice explanations, starts from the basics.

LinkAce is a self-hosted archive to collect links of your favorite websites.

Another bookmarking software. Similar in interface and features to linkding, a little more involved than shaarli.

Allows you to create 'lists', specifically themed sub-bookmarking pages that you can share on their own (or just keep to have a thematically bound bookmarking list for yourself), which is neat.

Can also share all links by default (i.e. have public bookmarking) like my good old shaarli.
Can theoretically share to a wide selection of apps (from mail, through facebook, reddit and the socials to trello, whatsapp and skype) but I am not sure I would ever use this.

Otherwise, the interface is a bit too involved for me: when on the main page, I just want to see a list of links while it shows me stats and 'most recent' stuff and the search is its own little page too.
Definitely a good program, just less for me I would guess.

A VNC server for wlroots based Wayland compositors.

Allows running a vnc server under wayland, simple. Only works for wlroots (see for e.g. KDE here ) but also works when running headless which is neat!

Use SQL queries to solve the murder mystery. Suitable for beginners or experienced SQL sleuths.

Lean SQL with a murder-mystery game. How cool!

Self-hosted platform to keep and share your content: web links, posts, passwords and pictures.

Bookmarking app like a bridge between shaarli and wallabag. Wants to save all sorts of different media and have a nice presentation UI with sharing of links, albums and even wants to be your password manager.

Probably a little too much for my needs (just need stable web page bookmarking and a strong search) and looks to be abandoned for the time being? (at least code-wise, author still seems to respond to issues).

A cli wrapper combining git and dvs. Instead of doing first dvc commit then git commit then individual pushes you can just do it with one fds commit.

Similarly with fds status which is probably the most used command - get a quick at-a-glance overview of current project status for both data and code.

By being built as a wrapper it of course still allows delving into the individual programs for more advanced operations. Pretty clever, actually!
