Problem description Jira is used inside SUSE to track various process/workflows.

It's not always straightforward to open a core dump originating from customer's environment, since there's a wide variety of versions of all the binaries involved - usual workflow is to install a VM with the SP that the customer is using, enable debuginfo repositories and then follow the buildid hints that gdb is providing. However this sounds like a bit of an overkill. Lately, there has been a debuginfod project announced:

Thinking about extending the typical Twitter app that let's a user bulk-delete their tweets (with a limit of 3200 each time). The main extension is to allow subscribers to this service to add a hashtag to their tweets that will put a time-to-delete

Salt is moving towards a plugable architecture using POP and Idem. This project is about experimenting with those new concepts by applying them to a real life case: the virt execution and state modules. The goals of this project are:

For years we have been discussing the idea to modularize SUSE Manager. This would enable developers to create their own extensions to SUSE Manager without needing to touch the core repository. There are several frameworks that could be helping in that direction. The goal here is to create a Proof of Concept with the virtualization features moved into an add-on.

The idea is to hack os-autoinst-distri-opensuse infrastucture and explore design patterns that can fit. The end point of this is to restructure the framework in such a way that the main-common.pm is more efficient, functional and readable.

Avahi is (among others) a domain names auto-configuration system for Linux compatible with Bonjour. The project is to dig into avahi source code to modernize it if possible and fix bugs.

Currently AWS uses a SMT solver to decide on public/non-public policies https://aws.amazon.com/blogs/security/protect-sensitive-data-in-the-cloud-with-automated-reasoning-zelkova/ Learn about SMT solvers & see how feasible using a smt solver is for supporting the more minimal policy set in ceph object storage RGW

Motivation

Running async actions in SUSE Manager lacks a user-friendly feedback. For instance, running a salt highstate on a system:

Testing GUIs is hard: unit tests require a tremendous amount of mocking and often don't capture the exact user input anyway, integration tests on the other hand are difficult to setup as they often require a dedicated infrastructure with virtual machines. libuitest should become something like the image recognition part of openQA: it receives a video or image stream from some source and searches for matches (e.g. button found, sound played). It should also be able to send clicks, key presses, strings, etc. back via an abstract API to a backend.

Once more mailprocessing has developed some bitrot, namely this recent crash: ```

transactional-update, the application to update read-only systems such as openSUSE MicroOS and openSUSE Kubic and the Transactional Server installations of openSUSE Leap, openSUSE Tumbleweed and SUSE Linux Enterprise Server, evolved from a POC to a fully fledged solution - and is currently completely written in Bash. This has been working really well in the past, but is gradually reaching its limits, especially when thinking about supporting additional file systems or ports to other Linux distributions - yes, we have a huge interest in other distributions adopting our technology. A C++ version would simplify those abstractions, but would it also make maintenance of the complete application easier? Check that as part of a POC and refresh C++ knowledge on the way there.

This issue has been blocked for a while due to time constraints so I want to take Hackweek 19 to work on it.

Put together a collection of ideas and resources to mentor people managers on how to make better decisions: - Useful mental models and how they work together

Learn and use tools to build/deploy SUSE/openSUSE to the KVM environment for developing kernel CVE patches and testing automation Steps :

Create DevOps automation for testing PTFs prior to delivering to customers, that will be available to each of the team members using standard L3 tools.

The Gameshell is a small game console based on AllWinner R16 (Cortex-A7, IIRC the same CPU that the RPi2). Currently is supporting Debian, and some community member ported ArchLinux on it. The goal of the project is to port the openSUSE MicroOS distribution into the device, providing a transactional upgrade process for a canonical IoT architecture. In the process I expect to learn about ARM7, uBoot and some kernel hacking.

Diagnosing issues with stalling desktop application (or a whole desktop environment) is difficult these days as the application often requires multiple processes interconnected with sockets, pipes, futexes, etc. to work and often it is not clear which process is the one responsible for blocking the whole ecosystem. The idea of this project is to write a tool that gathers information about processes in the system and for each process that is sleeping display the resource (file, socket, futex) it is waiting on as well as the process that is likely responsible for unblocking (feeding pipe, sending data to socket, unlock futex, ...). Once the information is gathered, we can also plot it for graphical displaying with tools like graphviz.

Solid Ground is an essential software tool for the daily tasks of an L3 agent. A continuous integration/continuous delivery (CI/CD), and even more a continuous deployment, approach is currently missing from its development ecosystem slowing down its release cycles. Current project aspires to sketch the design principles of such approach and if possible to end up with a functional CI/CD mechanism that will be utilized in the next software releases of Solid Ground.

I started 3 years ago creating a CNC, but soon last past 6 monts I realized that I could use it as a 3D printer. The software was good enough, the hardware and firmware had evolved. And now I could print 200x200x300 pieces with 0.1mm precision. But at soon I had this one finished, I decided to create a new compact, silent, light 3D printer.

Investigate possibilities for the distributed builds for Ceph to speed up builds. This task could have 2 scopes.

I got a Raspberry pi 4 not long ago, I'd like to install openSUSE Leap 15.2(Alpha) on it, and set up hass - Home Assistant, a open source home automation assistant on rpi4, then have some fun with it! Update: hassio dropped py3.6 support in Dec 2019, since Leap 15.2 stays with python 3.6 rather that python 3.7, I've to use Tumbleweed instead.

Many cases are Client-Server testing or Multi-Machine testing in FIPS area, I plan to hack and learn more deeply about Multi-Machine test automation in openQA. Refer to:

Take the oportunity to learn Kubernetes, to play with AWS and compare performance and availability of openQA and OBS instances and openSUSE Mirrors running on AWS. - https://aws.amazon.com/

ABF is a buildsystem developed by ROSA (rosalab.com) and OpenMandriva (https://www.openmandriva.org/) currently being used for their distribution. The build system is FOSS and is available to be deployed anywhere. (https://github.com/rosa-abf) (https://github.com/OpenMandrivaSoftware/docker-builder)

I'm hearing impaired. Where others have no issues following talks or dicussions, I often fail even grasp the bottom line what it's about. I've got hearing aids, but they help only so much. I also have an add-on device for my hearing aids that acts like a bluetooth headset. Unfortunately, making this thing work under my Linux desktop has been an ongoing, frustrating struggle. On the contrary, it works flawlessly with Android devices of different generations, and even with my lowly Gigaset phone. Actually, the thing works better with older kernels/Linux versions than with current TW. While I've little hope to solve the bluetooth audio issues on Linux for good, I hope at least to be able to understand better what's going wrong, and be able to slow down or even stop the deterioration I've observed lately.

The goal is to find a way for developing and simple testing an IONIC based multiplatform app with REST API on openSUSE. The focus is to find a way to secure token handling for SSO.

GitLab provides a bridge to connect to Gitter using an IRC client. The source code is at https://gitlab.com/gitlab-org/gitter/irc-bridge/

Create a tool which will make it possible to monitor the lifecycle of pods in a kubernetes cluster (as well as other types of tabular or structured data), and provide a convenient user interface for viewing and interpreting that data. This will be useful in development and testing of our kubernetes-based container platform (Cloud Application Platform), as it will allow us to better understand where things are going wrong when we encounter component failures. * Github

Description

Firecracker is an open-source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services.

I want to study the knowledge of openQA I will read the online documents and do some experiment in virtal-machine.

Have a play with SUSE CAP on AWS during this hackweek.

I plan to summary exist knowledge in filesystem part during hackweek. And learn some more feature about btrfs/xfs/ext4. The motivation is to speed up test result review in the future.

openSUSE Leap 15.2 is currently under development and it will be released soon. We would like to bring Kubernetes support for it and offer kubeadm deployment on it. As Kubernetes cluster container images we can use images from kubic project.

Working with some of the Linux modding communities I am aiming to make the ultimate guide / knowledge base for modifying the look and feel of your Linux install. The scope of this hackweek project is to get the initial framework set up using Jekyll with some basic content added. Further content will be added in the future.

As per the title I am aiming to investigate a much nicer conky default, I have a short list, but it depends on asking people nicely to license there work, if I have to create something from scratch it probably won't happen this hackweek. Now that themes such as Polycore are licensed so they are useable the aim is to build from there.

The Maintenance Coordination, Security and Quality Assurance department documentation is organized and handled on Confluence and there are several pages and how-to available for new team members or other colleagues searching for more information. The processes and workflow documentation is a key asset for on-boarding quickly new employees and for improving existing workflows.

The plan is to start working towards a rewrite of xdg-utils in python, focusing on the really bad bits such as dealing with desktop files and mime handling. In this hackweek, I want to split python-xdg into multiple libraries such as python-mime and python-desktop file and prepare them to be used in helper binaries to handle some of the more complex tasks currently done in shell.

Overview

uMEC (aka MicroMEC, or Micro-MEC) is a project under the Akraino Edge umbrella. SUSE joined in 2019 and together with partners we managed to create the 1st prototype infrastructure.

I recently bought a Lioncast LK200 RGB keyboard which is a nice piece of hardware and has exactly the look and feel I want. All basic functions work well under Linux. Unfortunately the manufacturer only provides user software to upload/download profiles and control the LEDs for Windows. The device can be configured and operates autonomously from any OS but color setup is a PITA and it's very easy to factory-reset, and lose all config. I approached them but Lioncast seems neither interested to support native Linux nor to provide protocol specs so one can implement it. I thought to take this as an example to learn about reading and reverse-engineering USB device software.

****The motivation is create a open source solution, base on this business astronomy products: AZWO Asiair

Libyui REST API

In the previous hack week project I was focused on implementing a REST API for testing the YaST modules.

define data types to collect informations about cameras and lenses to have a shared data store for lensfun and photo editors. Current state:

Finglonger is an internal tool used by the SUSE Manager team intended to make the life of the Round Robin Bug Guy easier. It was originally written by @fkobzik in Clojure. This is an attempt to learn some Go by reimplementing Finglonger.

Well, we often stuck in YaST team with knowledge what users really use and how much. But we have yast logs in many bug reports. And from those logs we can see which modules users use the most. So goal of this project is to write script that analyze given tarballs with logs and print result about usage of yast clients.

There are various home assistant solutions out there but all of them transfer your voice to some server for processing. This is a no-go for sane people although the technology is interesting and could be useful. There are various open source tools out there to achieve the same result but there is no turn key open source self hosted solution. The goal of this project is to implement a way to have a home assistant running locally - ideally with one command. The project that is closer to the desired result is Mycroft (https://mycroft.ai/). It is very easy to run the client side components using one docker command but their backend is running remotely. All the tools they use though are open source so it only needs one to do the work and package them in a nice little docker-compose file (https://mycroft-ai.gitbook.io/docs/about-mycroft-ai/faq#can-mycroft-run-completely-offline-can-i-self-host-everything).

Future of tools supporting editors in dealing with particular languages is in my opinion in the LSP protocol. Therefore I look with a bit of worry on the fact that there is no good LSP server based on the top of rope. python-language-server uses it a bit internally, the Microsoft Language Server for Python is in C#, so it is completely something different. The goal of this project is to write a very simple nucleus of the LSP server based solely on rope for the language analysis and actions, which would be at least able to do “jump to the definition of a symbol”.

Zero-ish downtime deploy on da cheap!

This project aims to get a 0-ish downtime deployments (very easily achievable with Kubernetes) just using:

Very often people find themselves wanting to store secrets in a way that either they can recover even if (for instance) their house burns down, or allow friends and family to recover if they pass away. Existing solutions to this problem are: * Too complicated to use for ordinary people.

• Check and verify SGML tools
• Parse and validate mostly markup-less files with SGML tools

https://gitlab.suse.de/l3ms/RES-weather/ needs some improvements, e.g. manual generation of statistics and reports.

At present it is our practice to "vendor" all dependencies for a Golang package. This has the advantage that everything is in one nice package and self contained but it has the disadvantage that dependencies are hidden and therefore security issues may slip through the cracks. The idea is to investigate and create automation "go2rpm" that generates a spec file with the necessary "BuildRequires:" such that the dependencies can be broken into golang- packages and we get rid of the implicit dependency inclusion via "vendor". The potential problem is scale, with some golang applications having thousands of dependencies.

GNOME Software supports distribution upgrade, that only requires a few clicks for upgrading your system. But it's not integrated into Leap. So this is that I plan to do this Hack Week.

Involved components

I would like to learn and play with RL/ML and Go ( gorgonia for example). The lack of Reinforcement Learning library in Golang makes me very sad, so I wanted to implement a RL algorithm and alongside create a small library for RL and go in general. On the other hand, I would like also to expand and add features on a project that I'm working on: https://github.com/mudler/luet . It's a package manager based on containers, focused on cloud/OTA-alike update delivery. It would be nice to combine the two ideas, for e.g. to achieve one feature.

Idea is to write FF plugin which would process raw autoinst log and display it in more readable form .

Recently, ConnMan got support for iwd and WireGuard. The current support is only a starting point and it needs some more changes in the core code base to support the cool features:

Summary Using K8s for managing VMs is a requirement in many environments, as not all applications are designed to be cloud-ready. Some projects like Kubevirt[1] and Virlet [2] aim to address this requirement. However, they introduce their own complexity, creating a parallel control plane for VMs. RancherVM [3] has a different approach, launching VMs as pods, but requires custom-built images.

I started Standford's machine learning course but after getting stuck in one assignment (ex4, Week5), it fell of the table due to lack of time and focus. I will use this Hack Week to make some progress on it.

Be familiar with the process of writing a test case in openQA by taking a ticket from a QA team.

I would like to set up a small backup server on my spare hardware What I have:

Learn how to develop and create some plugins/apps for rocketchat. One that comes to mind is to enhance gerrit links which all are enriched with the same text, no matter what you link. A plugin could extend those links into printing some proper info like the patch name so its easier to click on those.

With the approach of kernel 5.6 SGI Octanes are supported with builtin IO components. What's missing for a graphics workstation is a driver for the graphics card. There is already a not upstreamed framebuffer driver for Impact graphic cards. Since there will be no new framebuffer driver accepted upstream, the goal of this project is to convert the existing frame buffer driver to a DRM driver and make it ready to be sent upstream.

Continue improving my personal project, bard. Bard is a music manager for your music. It stores all information about your music collection in a Postgresql database . The current release can be used from a terminal and has the following working features:

There is a number of annoyances and pending improvements when working with the Salt Formula for provisioning Prometheus Exporters in Uyuni: - Fix issue with cleanup in case the monitoring entitlement is removed.

Based on an old customer feature request: zypper history command options so that it can show the security patches installed on a server and when they were installed, during a defined period of time.

The recent Banana Pi BPI-F2S board features a new Arm SoC SP7021 by Sunplus, which is not yet supported in mainline Linux. Prior to Hackweek I had prepared UART and interrupt controller drivers and Device Tree for Sunplus SP7021's Arm Cortex-A7 cores: GitHub branch f2s-next

Uyuni is an heterogeneous and giant project (actually it is a beast) made of many pieces, many languages, many internal architecture structures, and also very old and new technologies live in it. Said that, and based on the fact Uyuni delivers tons of features/functionalities not all the end users use, it is not trivial at all to understand

So I have 469.icu :), it's currently doing nothing... (and for sale) but in the meantime, I'd like to write an url shortener from scratch and deploy it on my own server

1) Explore postmarketOS, LineageOS on real device. 2) Explore Qualcomm mainlaining effort.

There are a number of items related to doing Virtualization CI and testing which I have a hard time getting to during my day job. I'll take Hackweek as an opportunity to get at least a little out of my normal space and improve our methods. This mainly focuses on QEMU/KVM and some of the efforts and infrastructure I've already got in various states of development, or at least investigation. Part of this effort is to try to leverage what is available in this space upstream, and to focus on watching the state of CI as it exists upstream, not just in our shipping products.

CephFS is awesome, but without a VPN it's not safe to be routed over the internet, and it lacks client support on many platforms. The Linux Kernel Library allows for the linux kernel to be built as a cross-platform user-space library and integrated into a regular Android, Windows, macOS, etc. application. This project combines CephFS, LKL and wireguard, and sprinkles some io-uring on top. My objectives are:

In a 2-node HA cluster without quorum server, since neither of the cluster nodes (partitions) has more than 50% votes in case of split-brain, we should configure corosync.conf to enable two_ndoe: 1, so that both nodes (partitions) will be granted "quorum". But there'll be potential fencing matches which could introduce double-fencing by chances. The current solution is using random/static fencing delays by configuring pcmk_delay_max/base parameters for stonith resources to prevent double-fencing.

Play with kiwi and liveCd capabilities to create a Small liveCD to get a rescue and multimedia system in less than 700MB. Will be a liveCD in Full french.

I plan to implement XEP-0308 for Profanity. Something that is asked for since 2016.

take my existing buildit.sh script (https://github.com/dmbyte/SES-scripts/blob/master/clusterbuilder/) and enhance it to be more of the installer experience needed. It would ideally be coupled with an autoyast file that does:

Hydrogen is a software drum machine and pattern editor. While it can export and play through MIDI, which is enough to play through my SR-16, it is not clear how one could record patterns and songs from Hydrogen.
