Few weeks ago whilst analyzing the possibility of using Terraform[1] via terraform-libvirt [2] plugin, I came across Terratest [3], which is an automated testing framework. My initial thoughts have been written here [4] but I'd still like to check out Terratest in more detail.

Learn Rust by following The Rust Programming Language book.

So far the style (color, shape, ...) of the devicegraph output of libstorage-ng is hard-coded. The user of the library should somehow be able to customize the style.

Following the work started in the last hackweek, Improve OBS service scripts, I will try to migrate current service script for workers to systemd unit, and at the same time, try to get rid of the sysv code.

Create a sound board that has the following requirements: * Works in Browser

The idea is to have a friendly way to access live cluster's nodes, compare outputs of simple commands and find out differences in tables data / structure. Current state: implemented and tested scripts which split table into ranges and then for each range check rows count and rows checksums.

When all of the SUSE Manager squads switched from SCRUM to a Kanban we lost estimations and therefore also the ability to do predictions. But there are other ways to get insights that are even more reliable, since they are based on anecdotal data. The lead and cycle times of issues are the two most important here. I'd like to extract those two for all of the issue from the spacewalk project and explore how they can be visualized in meaning- and helpful ways.

Create a new generic CUPS wrapper backend /usr/lib/cups/backend/monitor that runs in parallel with the actual backend to monitor it.

Following trademark and licensing issues with Grafana, explore the possibility of debranding Grafana and use that in SUSE Manager (and maybe others) Products are available from GitLab: https://gitlab.suse.de/susana

At SUSE Manager and Uyuni we use right now a set of bash scripts called sumaform-test-runner to run terraform and cucumber, send notifications and store cucumber results. However such scripts are currently hard to maintain and extend, and bash is clearly showing it's limitations when it comes to parsing cucumber results, working with JSON stuff, or using APIs. Besides it forces us to have credentials hardcoded at the main.tf files, which is a huge problem for making a public CI for Uyuni.

We've (mostly @cbruckmayer) put a significant amount of time into our performance measurement dashboards based on influx/grafana. I want to share this with the world because it's most awesome and easy to use. It's also nice if people don't go to some PaaS provider just for this...

Currently, the SUMA test-suite takes about 6 hours to complete, often fails in the first tests, which set up the environment for the rest of the tests, those tests are what we named "core features". To solve this problem we had planned to move from Jenkins Job to a Jenkins Pipeline, having stages to split the test suite into core features, initialize clients, secondary features. So,if one stage fails, the rest of the stages will not be executed.

There are attempts to solve some kernel deadlock with using lockless printk ringbuffer. The proposed implementation is pretty complex (6 stages, 6 write and 6 read barriers, two buffers, entries linked via list, ...) I have a idea how to make it easier with tracking the state and sequence number in one atomic variable. It might allow to remove the lists and many barriers. It is possible that it will just not work. Let's see.

Try to prototype an interactive dashboard for parts of the data available on SMELT.

Background

motivation

As an openQA contributor I could learn from openSUSE release managers how the overall process can be improved.

The goal is to run the Elastic Inference Demo managed by kubernetes on a Raspberry Pi4 Cluster with openSUSE Kubic. * The openSUSE Kubic image should configure itself correct at the first boot with ignition.

This hackweek I'll be working on Kanidm, an IDM system written in Rust for modern systems authentication. The github repo has a detailed "getting started" on the readme. Kanidm Github

Project here: https://confluence.suse.com/display/AAI/HackWeek19 Will keep working out of HackWeek as "best effort" personal project to make it evolve and keep learning.

There are multiple reasons for this project. First, I want to re-cap my ruby programming knowledge. Secondly, this course is available on pluralsight. This is project for 1-day, where I plan to continue and create some project and dive a little bit deeper into it. Here is the url for anyone interested: https://app.pluralsight.com/library/courses/code-school-rails-for-zombies/table-of-contents

Goal: I'd like to have the release process defined in markdown/git and use it as a source for process creation in redmine.

You can encrypt your servers root filesystem, but need to provide a password during the boot process in order to "unlock" and start the system. This is easy if you have physical access to the server by entering it via keyboard. But if you do not have physical access it's not that easy. This project is about to set up a server that might be able to have an encryted root filesystem which can be "unlocked" by entering the password via ssh.

The ESP8266 is a low-cost WI-Fi microchip with full TCP/IP stack and microcontroller capability. I want to explore the features and (in case of success) attach a BME280 to get temperature, humidity and barometric pressure information streamed over WI-Fi. As the price of both components is just around 10 EUR, this would be a nice add-on for my weather station at home...

Create a gnome-shell extension inspired from an Android app floating toolbox. floating toolbox

I want to create an exporter for a X instagram profiile using the Instagram API. The exporter should export some metrics on my user and then I can build perhaps some useful dashboard

I'm building a web-site for my drawing/painting things. This hackweek project I want to do more frontend related stuff like javascript/clojurescript and html for improving the layout and so on of the page.

qemu-devel.opensuse.org is a port forwarder to * 2 ARM Server

Research on BI tools to crawl eg. SCC data. This is an internal project, tracked at SUSE Confluence.

Acronyms are fun. Everyone at SUSE loves them. Just sometimes… you might not know what one stands for.

For a very long time, I have been planning to play with Crystal as possible substitute/complement for Ruby. With that goal, I have isolated a very small subset of the Ruby project I know the best (yast-storage-ng) and I want to migrate that subset to Crystal to get a general feeling about the language. See the repository with the experiment already in progress. There is no evil plan to migrate YaST to Crystal. This is just done in the Hack Week spirit of "what if". But if more people join maybe we could get this to an state in which some benchmarks can be executed to check what's the real gain in speed and memory consumption using Crystal instead of Ruby (note: speed and memory are not the only goals of the migration).

We have ActiveJob instrumentation in the OBS code base and a couple of panels in our grafana. Move this upstream to influxdb-rails. - OBS code

Start awesome/people-management and properly announce the awesome setup.

Move our agile team check, with some more elaborate assessment, online to office365

This hack week project is an Unity3D app, available in Android, IOS and HTML5 platforms. The idea is to welcome new joiners inviting them to play this game. The game will have questions about SUSE, the new joiners will need to ask other SUSE employees for the correct answer, socializing and learning SUSE culture at the same time. When they win the game an e-mail will be sent to a concrete e-mail address (it might be someone from facilities) and they will receive a small gift as Welcome Pack. For instance, they could receive the small chameleon or a t-shirt.

Hamster is important for may daily workflow, as I'm using it for time accounting. While hamster-time-tracker-2.2.2 itself, as shipped on Tumbleweed, depends on python3 only, the build process requires python2. It's therefore in danger to be kicked out of the TW repos. Updating to 3.x will likely require some homework. Edit after hackweek 19: Almost done. Hamster 3.0-beta is available from the "Office" project on OBS. This took more efforts than foreseen though, because I got involved in beta testing and ended up testing, fixing issues, and going through tedious discussions with the current lead developer.

The admin-tools appimage provides several samba team YaST packages in a portable way, such as yast2-aduc, yast2-gpmc, yast2-adsi, and yast2-dns-manager. Currently I build the appimage on obs, but this pulls in lots of unnecessary dependencies. Making it build independently would allow building on other distros. The difficult part here is going to be building minimal YaST dependencies.

Last year I developed Terracumber and, for the moment published it at one internal GitLab repository. We intended to replace the set of scripts we have to launch sumaform for the Uyuni and SUSE Manager CI, but lacked adding the monitoring part.

This project could get us rid of the last fbdev drivers we're stil shipping: efifb and vesafb. Platform drivers handle hardware that is not auto-detected, but somehow there. For graphics this would be VGA, VESA, or UEFI framebuffers. In SUSE Linux, we currently support VESA and UEFI with fbdev drivers. Those load early in the boot process and maintain graphics hardware until the actual driver takes over.

In financial markets traders try to win money buying cheap and selling expensive. To do that they need to understand what is going on on the market and also what will do the market in the future. So the idea is, if they have methods to do that, why can't we use it to understand what is going on in my business?

French ISP Free is providing a xDSL / Fiber modem, which includes a lot of features, including integrated NAS support and, more recently, allowing to run your own VMs (https://dev.freebox.fr/blog/?p=5450 sorry, in french) Those VMs needs to run as aarch64 guests and might requires some adaptions for easy install with the modem webUI (cloud-init support, etc).

The KEF LS50 Wireless are audiophile grade powered speakers that are fairly Linux friendly. But so far they can only be configured via an Android/iOS mobile app. I want to reverse engineer the custom binary protocol used by the apps, and build a simple Linux application to reconfigure things like DSP settings on the fly from the terminal.

The idea of this project is to learn more about SAP Gardener and its capabilities. Evaluate potentials and eventually include some capability around CaaSP that does not yet exist there.

Pinebook Pro SPECIFICATIONS

Last hackweek I created the pnp soundboard -> https://github.com/Devp00l/pnp-soundboard This time I want to encourage other people then myself to use it :)

I'm missing really badly the tool f.lux in my openSUSE machines. I really appreciate its usage specially when I'm using the computer late night. https://justgetflux.com/

This is a follow up to https://hackweek.suse.com/projects/architecting-a-machine-learning-project-with-suse-caasp. In the last hackweek I learned that in order to run machine learning workflows on top of SUSE CaaSP, the missing piece is to have libnvidia-containers and nvidia-containers-runtime-hook packaged.

"Egunean behin" (means "Once a day" in Basque) is a really popular Phone app/game in the Basque country. https://www.codesyntax.com/es/proyectos/egunean-behin (sorry, the description in english doesn't exist yet...)

There used to be a tool called tel that would show information about a user including his phone number, room number, etc: $ tel tux

Extend Stratos (https://github.com/SUSE/stratos) by adding the ability to integrate open-source Analysis tools such as Popeye, Kube Score, Anchore, Clair etc, so that users can run these tools on their clusters from Stratos and view the results from Stratos. Allow results to be viewed contextually - so errors/warnings from an analysis will be shown on the appropriate view - e.g. the namespace view, pods view etc.

The goal is to package terraform-provider-libvirt on Homebrew to deploy the SUSE SAP and HA automation on a remote KVM host from macOS. Result:

https://github.com/Johni0702/mumble-web To improve user experience for less technical users, a browser-based client would be cool.

A Community member at FOSDEM requested MicroOS for SystemZ - spend some time at Hackweek looking at it

For my 40th birthday I got from my friends a very special present, an USB Accelerator that brings machine learning inferencing to existing systems: https://coral.ai/products/accelerator

I am trying to build a cheap Kubernetes cluster on top of Kubic. * The purpose is to have production personal cluster.

In order to inspect rpm dependencies inside the distro I wrote some python command line tools that leverage libsolv. Since navigating the ball of wool that is the result of solving a package is on the command line, I'd like to create a web app. Implementation by means of Flask, bootstrap and jquery to keep it simple. UI should be entirely created on client side with Flask only server json endpoints.

The current geekos install at http://geekos.prv.suse.net/search is not reachable for employees outside of engineering. We want to move it to the SUSE IT maintained EKS cluster to make it available for all.

I run openSUSE TW and FF with i7-5600U Intel CPU. Calls with ~4 (video) participants work but my CPU load is approaching number of cores. In slightly bigger calls (>=6 participants) the CPU load was insufficient and audio packets were being dropped. I'd like learn more about webrtc video streams in order to reduce the client's CPU work or make it more adaptive when running with limited resources.

Project Description

This project aims to speed-up and simplify setup for analysis of application core files provided by our customers.

motivation

Test automation can be fun and openQA is good at it but it has limitations. This project is meant to find out where the limits are for applications with lots of things moving on the screen, e.g. a game. Completely unrelated, web based tools become the norm for many users, e.g. when working from a chromebook or similar environments. The idea here is to try to use only web based tools and not force users to use a terminal which can be frightening :) As a third requirement: Some people are not feeling comfortable using openQA "because tests are written in Perl". This is not necessarily true because tests are rather written using a simplistic test API and only a small subset of Perl knowledge is necessary, however, we still want to support other entry points so there is Python support added in https://github.com/os-autoinst/os-autoinst/pull/1558 . To find out what this new way is capable of this project should use only that Python support and find out any restrictions.

Project Description

I've been using open-source video editing software like Shotcut before and I used to be pretty happy with it. Nowadays, however, I need more sophisticated workflows that allow me to process n-log video, do color grading, synchronize video and audio from multiple sources, have better looking effects, and so on. I've reached the point where Shotcut just can't do what I would like it to.

Project Description

GTK+ software for two-factor authentication that supports both TOTP and HOTP.

Project Description

I've had a fairly modern AMD GPU for some time, but I haven't had time to check the current status of neural network based video editing. I know many are proprietary CUDA specific, sadly, even if projects themselves would be open source, but I'd like to check which ones would support OpenCL as well or any other means to use an AMD GPU with fully open source stack (including drivers).

There are couple of projects I work on, which need my attention and putting them to shape: * M2Crypto

Relax-and-Recover (ReaR) is used to recreate a destroyed system on compatible replacement hardware, see https://en.opensuse.org/SDB:Disaster_Recovery Currently ReaR requires basically 100% compatible replacement hardware.

Project Description

There are multiple network benchmark tools already, most popular probably being netperf and iperf. Each of them has its pros and cons but the biggest drawback probably is that netperf runs only one connection (flow) and while iperf can use multiple connections, it still runs in a single thread. For benchmarking of contemporary fast networks like 40Gb/s or 100Gb/s ethernet, this can be a severe limitation as the performance is often CPU bound. Even on 10Gb/s ethernet, we are often unable to saturate the medium if tunneling or complex packet processing is involved.

WozMania is an Apple ][ emulator on ARM processors that I wrote during my spare time. It works fine, but for the moment it's text-mode only.

Motivation

There is a (Windows-only) software for controlling / setting the color modes on the Genesis Thor 300 RGB keyboard. I believe the communication protocol can be reverse engineered and an open-source variant for the accompanied software can be created and full potential of the keyboard unlocked.

Project Description

The Commanded Elixir CQRS framework provides an EventStoreDB adapter that uses TCP protocol which is being phased out.

Motivation

When automating tasks often the requirement comes up to retry commands, for example when network connections are involved and commands do not return successfully immediately or if resources are temporarily not available. Sometimes a simple for-loop in bash is sufficient. Sometimes it is necessary to use additional waiting between retries, sometimes timeouts are desired. Getting all those combinations right can be tedious and error-prone so a generic "retry" command should be available in usual environments so we should provide a retry command to openSUSE distributions.
