New KDE Plasma notification app/applet by apappas
Description
My memory is terrible so I depend a lot on notifications to carry me through the workday. As a plasma user I am ok with the current applet, but I don't love it. It is too small for the centrality it has in my day. Also I dislike how you can not go back to notifications you have dismissed
Goals
Develop a plasma app that * must gather notifications without disrupting the existing notification app * must offer the ablity to refer to dismissed/archived/seen notification up to some defined point in the past * must allow deletion of notifications
RISC-V emulator in GLSL capable of running Linux by favogt
Description
There are already numerous ways to run Linux and some programs through emulation in a web browser (e.g. x86 and riscv64 on https://bellard.org/jslinux/), but none use WebGL/WebGPU to run the emulation on the GPU.
I already made a PoC of an AArch64 (64-bit Arm) emulator in OpenCL which is unfortunately hindered by a multitude of OpenCL compiler bugs on all platforms (Intel with beignet or the new compute runtime and AMD with Mesa Clover and rusticl). With more widespread and thus less broken GLSL vs. OpenCL and the less complex implementation requirements for RV32 (especially 32bit integers instead of 64bit), that should not be a major problem anymore.
Goals
Write an RISC-V system emulator in GLSL that is capable of booting Linux and run some userspace programs interactively. Ideally it is small enough to work on online test platforms like Shaderoo with a custom texture that contains bootstrap code, kernel and initrd.
Minimum:
riscv32 without FPU (RV32 IMA) and MMU (µClinux), running Linux in M-mode and userspace in U-mode.
Stretch goals:
FPU support, S-Mode support with MMU, SMP. Custom web frontend with more possibilities for I/O (disk image, network?).

OpenGL 4.5 Quick Reference Card
Result as of Hackweek 2024
WebGL turned out to be insufficient, it only supports OpenGL ES 3.0 but imageLoad/imageStore needs ES 3.1. So we switched directions and had to write a native C++ host for the shaders.
As of Hackweek Friday, the kernel attempts to boot and outputs messages, but panics due to missing memory regions.
Since then, some bugs were fixed and enough hardware emulation implemented, so that now Linux boots with framebuffer support and it's possible to log in and run programs!

YQPkg - Bringing the Single Package Selection Back to Life by shundhammer
tl;dr
Rip out the high-level YQPackageSelector widget from YaST and make it a standalone Qt program without any YaST dependencies.
See section "Result" at the bottom for the current status after the hack week.
Current Status
See the development status issue at the GitHub repo.
tl;dr: It's usable now with all the key features.
It does real package installation / removal / update with reasonable user feedback.
The Past and the Present
We used to have and still have a powerful software selection with the YaST sw_single module (and the YaST patterns counterpart): You can select software down to the package level, you can easily select one of many available package versions, you can select entire patterns - or just view them and pick individual packages from patterns.
You can search packages based on name, description, "requires" or "provides" level, and many more things.
The Future
YaST is on its way out, to be replaced by the new Agama installer and Cockpit for system administration. Those tools can do many things, but fine-grained package selection is not among them. And there are also no other Open Source tools available for that purpose that even come close to the YaST package selection.
Many aspects of YaST have become obsolete over the years; many subsystems now come with a good default configuration, or they can configure themselves automatically. Just think about sound or X11 configuration; when did you last need to touch them?
For others, the desktops bring their own tools (e.g. printers), or there are FOSS configuration tools (NetworkManager, BlueMan). Most YaST modules are no longer needed, and for many others there is a replacement in tools like Cockpit.
But no longer having a powerful fine-grained package selection like in YaST sw_single will hurt. Big time. At least until there is an adequate replacement, many users will want to keep it.
The Idea
YaST sw_single always revolved around a powerful high-level widget on the abstract UI level. Libyui has low-level widgets like YPushButton, YCheckBox, YInputField, more advanced ones like YTable, YTree; and some few very high-level ones like YPackageSelector and YPatternSelector that do the whole package selection thing alone, working just on the libzypp level and changing the status of packages or patterns there.
For the YaST Qt UI, the YQPackageSelector / YQPatternSelector widgets work purely on the Qt and libzypp level; no other YaST infrastructure involved, in particular no Ruby (or formerly YCP) interpreter, no libyui-level widgets, no bindings between Qt / C++ and Ruby / YaST-core, nothing. So it's not too hard to rip all that part out of YaST and create a standalone program from it.
For the NCurses UI, the NCPackageSelector / NCPatternSelector create a lot of libyui widgets (inheriting YWidget / NCWidget) and use a lot of libyui calls to glue them together; and all that of course still needs a lot of YaST / libyui / libyui-ncurses infrastructure. So NCurses is out of scope here.
Preparatory Work: Initializing the Package Subsystem
To see if this is feasible at all, the existing UI examples needed some fixing to check what is needed on that level. That was the make-or-break decision: Would it be realistically possible to set the needed environment in libzypp up (without being stranded in the middle of that task alone at the end of the hack week)?
Yes, it is: That part is already working:

Port some classic game to Linux by MDoucha
Let's pick some old classic game, reverse engineer the data formats and game rules and write an open source engine for it from scratch. Some games from 1990s are simple enough that we could have a playable prototype by the end of the week.
Write which games you'd like to hack on in the comments. Don't forget to check e.g. on Open Source Game Clones, Github and SourceForge whether the game is ported already.
Hack Week 24 - Master of Orion II: Battle at Antares & Chaos Overlords
Work on Master of Orion II continues but we can hack more than one game. Chaos Overlords is a dystopian, lighthearted, cyberpunk turn-based strategy game originally released in 1996 for Windows 95 and Mac OS. The player takes on the role of a Chaos Overlord, attempting to control a city. Gameplay involves hiring mercenary gangs and deploying them on an 8-by-8 grid of city sectors to generate income, occupy sectors and take over the city.
How to ~~install & play~~ observe the decompilation progress:
- Clone the Git repository
- A playable reimplementation does not exist yet, but when it does, it will be linked in the repository mentioned above.
Further work needed:
- Analyze the remaining unknown data structures, most of which are related to the AI.
- Decompile the AI completely. The strong AI is part of the appeal of the game. It cannot be left out.
- Reimplement the game.
Hack Week 20, 21, 22 & 23 - Master of Orion II: Battle at Antares
Master of Orion II is one of the greatest turn-based 4X games of the 1990s. Explore the galaxy, colonize planets, research new technologies, fight space monsters and alien empires and in the end, become the ruler of the galaxy one way or another.
How to install & play:
- Clone the Git repository
- Run
./bootstrap; ./configure; make && make install - Copy all *.LBX files from the original Master of Orion II to the installation data directory (
/usr/local/share/openorion2by default) - Run
openorion2
Further work needed:
- Analyze the rest of the original savegame format and a few remaining data files.
- Implement most of the game. The open source engine currently supports only loading saved games from the original version and viewing the galaxy map, fleet management and list of known planets.
Hack Week 19 - Signus: The Artifact Wars
Signus is a Czech turn-based strategy game similar to Panzer General or Battle Isle series. Originally published in 1998 and open-sourced by the original developers in 2003.
How to install & play:
- Clone the Git repository
- Run
./bootstrap; ./configure; make && make installin bothsignusandsignus-datadirectories. - Run
signus
Further work needed:
- Create openSUSE package
- Implement full support for original game data (the open source version uses slightly different data file contents but original game data can be converted using a script).
Try to render Agama in a TUI browser by ancorgs
Description
Agama is a new Linux installer that will be very likely used for SLES 16. It offers a modern and convenient web interface that can be executed both locally and remotely.
But of course some users will miss the old TUI (ncurses) interface of the YaST installer.
So I want to experiment whether would it be possible to render a simplified version of the web interface for TUI browsers. That's only doable and maintainable if we keep the current technology stack we use for rendering the full-blown page, simply replacing complicated UI elements with others that are easy to render. That means the browser would need to support Javascript.
Chawan seems to be almost there regarding support for Javascript, XHR and related technologies. But according to this conversation, the next missing piece would be to support recursive import of module script tags.
Unfortunately, Chawan is written in Nim and I'm pretty sure a week is not enough time for me to learn Nim, implement the feature at Chawan and then fix whatever is the next obstacle on the Agama side.
But if someone could take care of the Nim part, I would do the same with the Agama one. So this is basically a call for help to get this project even started.
Design the new UI for storage configuration at Agama by ancorgs
Description
We are in the process of re-designing the web user interface to configure storage at Agama. We expected to have a clear idea of what we wanted before starting Hack Week. But the idea is still not that clear. So I will use use my Hack Week time to try several prototypes since I really want this to be done.
Goals
Have a prototype using Patternfly components and addressing all the use-cases we want to cover. Easy for the easy cases. Capable for the complex ones.
Editor mode at Agama web interface by ancorgs
Description
Agama is a new Linux installer that will be very likely used for SLES 16.
It takes a configuration (in JSON format) as input. And offers several interfaces to build that configuration in an easy and interactive way.
I was considering the possibility to add to the web interface a "text editor" mode similar to the XML editor available at virt-manager. That could be used to see how the changes in the UI translate into changes on the configuration.
Goals
- Refresh my knowledge about UI development for Agama, since there was a major overhaul recently (adopting TanStack Query) and I need to learn the new way to do things.
- Please hackers who always want to know how things work internally. :-)
obs-service-vendor_node_modules by cdimonaco
Description
When building a javascript package for obs, one option is to use https://github.com/openSUSE/obs-service-node_modules as source service to get the project npm dependencies available for package bulding.
obs-service-vendornodemodules aims to be a source service that vendors npm dependencies, installing them with npm install (optionally only production ones) and then creating a tar package of the installed dependencies.
The tar will be used as source in the package building definitions.
Goals
- Create an obs service package that vendors the npm dependencies as tar archive.
- Maybe add some macros to unpack the vendor package in the specfiles

Agama Expert Partitioner by joseivanlopez
Description
Agama is a new Linux installer that will be very likely used for SLES 16.
It offers an UI for configuring the target system (language, patterns, network, etc). One of the more complex sections is the storage configuration, which is going to be revamped. This project consists on exploring the possibility of having something similar to the YaST Expert Partitioner for Agama.
Goals
- Explore different approaches for the storage UI in Agama.
