openSUSE Lounge by Ishwon

Description

openSUSE Lounge is a membership management platform for the openSUSE Project. It aims to simplify how we maintain member records, track membership status, and support election processes.

The platform provides Membership Officials with an easier way to keep the membership database accurate and up to date. It also helps Election Officials export the latest voter list and report issues such as bounced voter-credential emails, giving the Membership team early visibility into outdated or inactive accounts.

Goals

This project seeks to make openSUSE membership management more efficient, reliable, and transparent.

Long-term plans include enabling contributors to apply for membership directly through the platform and improving coordination between Membership and Election teams.

Sim racing track database by avicenzi

Description

Do you wonder which tracks are available in each sim racing game? Wonder no more.

Goals

Create a simple website that includes details about sim racing games.

The website should be static and built with Alpine.JS and TailwindCSS. Data should be consumed from JSON, easily done with Alpine.JS.

The main goal is to gather track information, because tracks vary by game. Older games might have older layouts, and newer games might have up-to-date layouts. Some games include historical layouts, some are laser scanned. Many tracks are available as DLCs.

Initially include official tracks from:

• ACC
• iRacing
• PC2
• LMU
• Raceroom
• Rennsport

These games have a short list of tracks and DLCs.

Resources

The hardest part is collecting information about tracks in each game. Active games usually have information on their website or even on Steam. Older games might be on Fandom or a Wiki. Real track information can be extracted from Wikipedia or the track website.

Casky – Lightweight C Key-Value Engine with Crash Recovery by pperego

Description

Casky is a lightweight, crash-safe key-value store written in C, designed for fast storage and retrieval of data with a minimal footprint. Built using Test-Driven Development (TDD), Casky ensures reliability while keeping the codebase clean and maintainable. It is inspired by Bitcask and aims to provide a simple, embeddable storage engine that can be integrated into microservices, IoT devices, and other C-based applications.

Objectives:

• Implement a minimal key-value store with append-only file storage.
• Support crash-safe persistence and recovery.
• Expose a simple public API: store(key, value), load(key), delete(key).
• Follow TDD methodology for robust and testable code.
• Provide a foundation for future extensions, such as in-memory caching, compaction, and eventual integration with vector-based databases like PixelDB.

Why This Project is Interesting:

Casky combines low-level C programming with modern database concepts, making it an ideal playground to explore storage engines, crash safety, and performance optimization. It’s small enough to complete during Hackweek, yet it provides a solid base for future experiments and more complex projects.

Goals

• Working prototype with append-only storage and memtable.
• TDD test suite covering core functionality and recovery.
• Demonstration of basic operations: insert, load, delete.
• Optional bonus: LRU caching, file compaction, performance benchmarks.

Future Directions:

After Hackweek, Casky can evolve into a backend engine for projects like PixelDB, supporting vector storage and approximate nearest neighbor search, combining low-level performance with cutting-edge AI retrieval applications.

Work on kqlite (Lightweight remote SQLite with high availability and auto failover). by epenchev

Description

Continue the work on kqlite (Lightweight remote SQLite with high availability and auto failover).
It's a solution for applications that require High Availability but don't need all the features of a complete RDBMS and can fit SQLite in their use case.
Also kqlite can be considered to be used as a lightweight storage backend for K8s (https://docs.k3s.io/datastore) and the Edge, and allowing to have only 2 Nodes for HA.

Goals

Push kqlite to a beta version.
kqlite as library for Go programs.

Uyuni read-only replica by cbosdonnat

Description

For now, there is no possible HA setup for Uyuni. The idea is to explore setting up a read-only shadow instance of an Uyuni and make it as useful as possible.

Possible things to look at:

• live sync of the database, probably using the WAL. Some of the tables may have to be skipped or some features disabled on the RO instance (taskomatic, PXT sessions…)
• Can we use a load balancer that routes read-only queries to either instance and the other to the RW one? For example, packages or PXE data can be served by both, the API GET requests too. The rest would be RW.

Goals

• Prepare a document explaining how to do it.
• PR with the needed code changes to support it

Help Create A Chat Control Resistant Turnkey Chatmail/Deltachat Relay Stack - Rootless Podman Compose, OpenSUSE BCI, Hardened, & SELinux by 3nd5h1771fy

Description

The Mission: Decentralized & Sovereign Messaging

FYI: If you have never heard of "Chatmail", you can visit their site here, but simply put it can be thought of as the underlying protocol/platform decentralized messengers like DeltaChat use for their communications. Do not confuse it with the honeypot looking non-opensource paid for prodect with better seo that directs you to chatmailsecure(dot)com

In an era of increasing centralized surveillance by unaccountable bad actors (aka BigTech), "Chat Control," and the erosion of digital privacy, the need for sovereign communication infrastructure is critical. Chatmail is a pioneering initiative that bridges the gap between classic email and modern instant messaging, offering metadata-minimized, end-to-end encrypted (E2EE) communication that is interoperable and open.

However, unless you are a seasoned sysadmin, the current recommended deployment method of a Chatmail relay is rigid, fragile, difficult to properly secure, and effectively takes over the entire host the "relay" is deployed on.

Why This Matters

A simple, host agnostic, reproducible deployment lowers the entry cost for anyone wanting to run a privacy‑preserving, decentralized messaging relay. In an era of perpetually resurrected chat‑control legislation threats, EU digital‑sovereignty drives, and many dangers of using big‑tech messaging platforms (Apple iMessage, WhatsApp, FB Messenger, Instagram, SMS, Google Messages, etc...) for any type of communication, providing an easy‑to‑use alternative empowers:

• Censorship resistance - No single entity controls the relay; operators can spin up new nodes quickly.
  
• Surveillance mitigation - End‑to‑end OpenPGP encryption ensures relay operators never see plaintext.
  
• Digital sovereignty - Communities can host their own infrastructure under local jurisdiction, aligning with national data‑policy goals.
  

By turning the Chatmail relay into a plug‑and‑play container stack, we enable broader adoption, foster a resilient messaging fabric, and give developers, activists, and hobbyists a concrete tool to defend privacy online.

Goals

As I indicated earlier, this project aims to drastically simplify the deployment of Chatmail relay. By converting this architecture into a portable, containerized stack using Podman and OpenSUSE base container images, we can allow anyone to deploy their own censorship-resistant, privacy-preserving communications node in minutes.

Our goal for Hack Week: package every component into containers built on openSUSE/MicroOS base images, initially orchestrated with a single container-compose.yml (podman-compose compatible). The stack will:

• Run on any host that supports Podman (including optimizations and enhancements for SELinux‑enabled systems).
  
• Allow network decoupling by refactoring configurations to move from file-system constrained Unix sockets to internal TCP networking, allowing containers achieve stricter isolation.
• Utilize Enhanced Security with SELinux by using purpose built utilities such as udica we can quickly generate custom SELinux policies for the container stack, ensuring strict confinement superior to standard/typical Docker deployments.
• Allow the use of bind or remote mounted volumes for shared data (/var/vmail, DKIM keys, TLS certs, etc.).
  
• Replace the local DNS server requirement with a remote DNS‑provider API for DKIM/TXT record publishing.
  

By delivering a turnkey, host agnostic, reproducible deployment, we lower the barrier for individuals and small communities to launch their own chatmail relays, fostering a decentralized, censorship‑resistant messaging ecosystem that can serve DeltaChat users and/or future services adopting this protocol
