A self-hosted version somewhat akin to something like nomie or jrnl. Supports markdown and can be interacted with through API - so could easily also be integrated with for example jrnl to auto-upload or download new entries.

Another fast terminal, written in rust. A lot reminds me of alacritty (though this comes with more extensive features like tabs and multiplexing on its own).

I guess, it reminds me of a terminal looking like alacritty with a feature-set more akin to kitty (which sounds like a good thing!)

Lastly, the terminal implements both sixel and kitty image protocol support so that's nice. Should try it one of these days!

A really interesting open-source (and open data friendly as far as I can see) tool for writing, publishing, sharing, exporting, and interacting on (think peer review) articles and scientific writings. Can probably also be used for other writings but that's the primary intent.

Seems really interesting, as in should delve deeper with this one. Built on W3C standards uses OpenID and other interesting tidbits.

Penpot - The Open-Source design & prototyping platform - GitHub - penpot/penpot: Penpot - The Open-Source design & prototyping platform

An out-of-the-box solution to self-hosting a wide variety of services without much setup.
Can be used to implement IRC, Matrix, XMPP and E-Mail hosting for a circle of friends (also takes care of simple account management afaik); some web office software (collaborative editing, wiki, website hosting) file sharing (I2p, torrent, bepasty, plain file sharing) and privacy uses (metasearch engines, proxying, i2p).

Everything seems to be documented pretty nicely on the debian wiki. Probably less flexible than docker container setup but not bad.

Steampipe is an open source tool to instantly query your cloud services (e.g. AWS, Azure, GCP and more) with SQL. No DB required.

Has a commandline interface and everything, seems very nice indeed.

Open-source collaborative spreadsheet editing application - seems fairly mature

Play Gothic 2 on modern systems with ease! Open source reimplementation of the game engine.

Open-source smartwatch that is fully arduino programmable (run by an ESP32), usually lasts 5-7 days and costs around $50.

Quite a few watchface examples exist online. From what I understand, the watchface is the firmware for this clock,
so no too easy changes there.

There are assembly kits with a case that can be bought for some $ more that will keep the watch a bit more safe (though not e.g. swimmingpool ready). The watch/display so far only exists in square shape.

Brilliant short explanation of the difference between the three popular FOSS (/OSS) licenses.
Boiling it down to 'what are you afraid of' really helps quick decision-making.

Simple, efficient and pretty.
A minimal GUI Journaling application - it gets out of your way and allows you to write in markdown.

One neat feature is its calendar view which lists the quick titles of your journal entries for days passed and thus gives you an overview of what you did when and when you were journaling.

If you need a terminal equivalent use jrnl instead.

A free and cloudless replacement for your gadget vendors' closed source Android applications. See the list for supported devices. https://gadgetbridge.org

Many many Linux softwares. Mostly useful as an overview for someone looking for a software in a specific area of computing (audio engineering, writing, database editing, programming, ..) since they are nicely sorted and allow an overview of FOSS alternatives to various software needs.

Mimcs photoshop a little more - especially in layout and shortcuts - by changing GIMP settings around.
Also installs a ton of fonts by default.
