I will focus on the real-time client-server communication using websockets. I can also help on the frontend side with the javascript dealing with the server communication.

Create a DRM driver for VGA video cards by tdz
Yes, those VGA video cards. The goal of this project is to implement a DRM graphics driver for such devices. While actual hardware is hard to obtain or even run today, qemu emulates VGA output.
VGA has a number of limitations, which make this project interesting.
- There are only 640x480 pixels (or less) on the screen. That resolution is also a soft lower limit imposed by DRM. It's mostly a problem for desktop environments though.
- Desktop environments assume 16 million colors, but there are only 16 colors with VGA. VGA's 256 color palette is not available at 640x480. We can choose those 16 colors freely. The interesting part is how to choose them. We have to build a palette for the displayed frame and map each color to one of the palette's 16 entries. This is called dithering, and VGA's limitations are a good opportunity to learn about dithering algorithms.
- VGA has an interesting memory layout. Most graphics devices use linear framebuffers, which store the pixels byte by byte. VGA uses 4 bitplanes instead. Plane 0 holds all bits 0 of all pixels. Plane 1 holds all bits 1 of all pixels, and so on.
The driver will probably not be useful to many people. But, if finished, it can serve as test environment for low-level hardware. There's some interest in supporting old Amiga and Atari framebuffers in DRM. Those systems have similar limitations as VGA, but are harder to obtain and test with. With qemu, the VGA driver could fill this gap.
Apart from the Wikipedia entry, good resources on VGA are at osdev.net and FreeVGA
Create DRM drivers for VESA and EFI framebuffers by tdz
Description
We already have simpledrm for firmware framebuffers. But the driver is originally for ARM boards, not PCs. It is already overloaded with code to support both use cases. At the same time it is missing possible features for VESA and EFI, such as palette modes or EDID support. We should have DRM drivers for VESA and EFI interfaces. The infrastructure exists already and initial drivers can be forked from simpledrm.
Goals
- Initially, a bare driver for VESA or EFI should be created. It can take functionality from simpledrm.
- Then we can begin to add additional features. The boot loader can provide EDID data. With VGA hardware, VESA can support paletted modes or color management. Example code exists in vesafb.
Finish gfxprim application multiplexor (window manager) by metan
Project Description
I've implemented drivers for a few e-ink displays during the last hackweek and made sure that gfxprim widgets run nicely on e-ink as well. The missing piece to have a portable e-ink computer/reader/music player/... is a application that can switch between currently running applications and that can start new applications as well. Half of the solution is ready, there is a proxy gfxprim backend where applications render into a piece of a shared memory and input events (e.g. keyboard, mouse) can be multiplexed. What is missing is an interface (possibly touchscreen friendly as well) to make it user friendly.
Goal for this Hackweek
Make nekowm usable "window manager".

New openSUSE-welcome by lkocman
Project Description
Let's revisit our existing openSUSE welcome app.
My goal was to show Leap 16 in a new coat. Welcome app adds to the first time use experience. We've recently added donation button to our existing welcome.
Some things that I recently wanted to address were EOL and possibly upgrade notification.
I've already done some experiments with mint welcome app, but not sure if it's better than the existing one.
There is also a PR to rework existing app https://github.com/openSUSE/openSUSE-welcome/pull/36 (this should be considered as an option too)
Goal for this Hackweek
New welcome app, possibly with EOL notification for Leap.
1) Welcome application(s) with (rebrand changes) maintained under github.com/openSUSE
2) Application is submitted to openSUSE:Factory && openSUSE:Leap:16.0
3) Updated needles in openQA (probably post hackweek)
Resources
Reddit discussion about the best welcome app out there.

Jenny Static Site Generator by adam.pickering
Description
For my personal site I have been using hugo. It works, but I am not satisfied: every time I want to make a change (which is infrequently) I have to read through the documentation again to understand how hugo works. I don't find the documentation easy to use, and the structure of the repository that hugo requires is unintuitive/more complex than what I need. So, I have decided to write my own simple static site generator in Go. It is named Jenny, after my wife.
Goals
- Pages can be written in markdown (which is automatically converted to HTML), but other file types are also allowed
- Easy to understand and use
- Intuitive, simple design
- Clear documentation
- Hot reloading
- Binaries provided for download
- Future maintenance is easy
- Automated releases

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.
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. :-)
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.
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.
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
