LVM support for Guix System Distribution

With GNU Guix 0.8.1 and it's distribution there is still lack of LVM support. As I'm probably the only user of LVM, I need to hack support into initrd myself.

ESP8266 Tinkering

The ESP8266 is an interesting little device that has been around for a while. It has the potential to support some interesting IoT applications. There is Ardunio core support for this device <https://github.com/esp8266/Arduino> and a rich set of libraries to help developers get started.

0 Background This will be a verification test for Intel i915, code has been merged into kernel 4.16 and qemu 2.12, will provide a setup manual as output.

I'll spend half of hackweek preparing for the CISSP certification, in the other half I want to learn Ghidra (https://ghidra-sre.org/) and solve some reverse engineering quests with it

Project Description

Further refine (based on last year's sca-L0 project) the automation and the functionality of an L0 approach to collect, analyze and provide notifications and next-step guidance across the data pipeline from an individual system all the way to an initial support request review. In general this is like an AIOps/ITOps edge-core workflow.

Project Description

The libkdumpfile library includes Python bindings. They are implemented as manually created C code for CPython. This is hard to maintain and/or port to alternative Python implementations.

Gerrit is used for code reviews by openstack and its related projects (e.g. chef cookbooks). The web interface is too slow when you get 100 changes to review each day. It would be nice to have a faster CLI. There are already some python client libraries available. I am thinking about either doing this as a standalone application with python and something like ncurses or an emacs/lighttable plugin. https://github.com/mapleoin/gerrit-el

Description

I noticed during home office times as well as with multiple people in one office how quickly air quality drops, which affects concentration and finally performance, as it causes tiredness and headache. I want a device that continuously measures the quality and reminds me in time to make adjustments to the airco (if available) or when to air the room, or take a break outside. Parameters to measure are at least temperature, humidity and CO2 level. The device should be stand-alone and potentially battery powered, with the option to connect to other devices such as PCs or smart phones through Wifi, Bluetooth, Serial, ...

Main goal is to take a step back from work related areas and do something creative and relaxing. In my free time I occasionally do digital paintings/drawings where I usually try to use free and opensource software: Painting: Krita

Project Description

Lay out a mock version of an existing SUSE R&D process in JIRA. The process should have a reasonable amount of complexity, like

L10N for the book entitled Designing with LibreOffice by Bruce Byfield

Project Description

The goals:

Learning boot loader related knowledge

Learn about boot manager, including trusted computing, disk encryption, EFI, storage and more

The primary arcade machine emulator is MAME, and it has a very specific format for romset compression. I have previously started a project call pyros that allows the creation and update of MAME romsets. The project consists of the following tools: * pyrex: Tool to create an executable Bash script that will take unorganized files and put them into an organized MAME romset.

In SUSE Manager we want to offer support for bootstrapping systems that don't have the salt-minion installed and configured yet. This can be done using salt-ssh given just a hostname, username and password. See the docs about salt rosters for even more options. What we are missing: - Support for using salt-ssh in our library

Project Description

Maintenance Coordination team has a set of tools called MTK (Maintenance ToolKit) that is extremely useful to the Maintenance team and can be used by a other teams to increase the productivity and automate common tasks related to the maintenance process.

Intel Active Management Technology (AMT) is hardware and firmware technology for remote out-of-band management of personal computers, this hackweek I'd like to spend some time to learn how to setup Intel AMT on my workstation and X201 with VNC enabled.

During the hackweek i want also to learn more about this topic. https://github.com/dastergon/awesome-chaos-engineering

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

The idea would be to create a qt5/kde5 based utility that can use local raw images as well as download a list of sources from a remote site. The idea is to provide a user interface that can be used by any user as well as a user interface that can be used in kiosk mode for booths so that a visitor can put a usb pendrive in any usb slot, select the image he/she wants to write to it and get it written in parallel to other usb memories. https://github.com/openSUSE/imagewriter seems to be abandoned, so probably part of the backend will be reused and the user interface will be rewritten from scratch, but anyway this will be reconsidered at the first task in the project.

i want to spend some day of my hackweek to improve salt-toaster https://github.com/openSUSE/salt-toaster

The idea is simple. Dice is a light weight build service for KIWI images with full control over the build power by the user. At SUSE we have the buildservice which is the full professional version of a build service for packages, images and also products. As a normal user I can provide input and I get some output but I have no control what happens with my data, when it's being processed and where it's being processed. That's by design and works great, thus not meant negatively. I'm a 100% fan of the buildservice

The openstack-helm project run Openstack in a Kubernetes cluster using helm charts. The goal of the project is to able to run it in OpenSUSE, and if successful as a bonus add a job that runs with OpenSUSE to the gates runs with OpenSUSE to the gates

RISC-V boot deep dive (Boot FLOW from 0 to Linux Kernel)

Make RISC-V boot like rest of industry U-boot for embedded, UEFI for consumer and servers

Background

A dashboard for testing and analysis xfstests results just initial this year. It has a lot of performance issues to fix, and it also needed to add more features to get usable. Also bootstrap looks very easy to use, plan to learn some frontend knowledge for fun.

While auto-mounting a VFAT volume in a desktop environment, there is no way to select required mount options for the particular volume. But there is no combination of options that will fit to all purposes. Without being able to choose mount options, some tasks work in an inferior way.

Description

One of the PuppetLabs guys is trying to enforce best practices on administering Puppet modules, by using base modules and build services and roles on top of them. That way we can re-use external / third-party modules from forge.puppetlabs.com, ideally without touching them at all. He names that "the Lego approach". Full article.

Project Description

Make sure that as many as possible packages in openSUSE:Factory are up to date

Project Description

CI/CD, which stands for continuous integration (CI) and continuous delivery (CD), creates a faster and more precise way of combining the work of different people into one cohesive product. In application development and operations (DevOps), CI/CD streamlines application coding, testing and deployment by giving teams a single repository for storing work and automation tools to consistently combine and test the code to ensure it works.

i want to make a prototype of a watch for waking up me in the night in order to take care of my daughter. this watch includes arm based MCU with time display on panel(OLED or LED), vibrate, beeper. using 3D printer for the box of this watch.

Create a console application for a crossword puzzle generator that can be fed with a custom list of word+explanation pairs. It may be used by people to quickly familiarize with a specific topic (e.g. a knowledge area, new hires to the company ...) to at least understand the terminology and the abbreviations that are used. Or to just have some distraction and fun :-) I think it consists of three components:

In the past, some customers ever complained that OCFS2 file system performance went down when listing a big directory (e.g. include 400k files). According to my preliminary investigation, this performance problem is related to file system block allocation algorithm. Then, I want to look at the current mainstream file systems (e.g. EXT4, XFS, etc) block allocation algorithms in this hack week, compare and analysis these algorithms advantages/disadvantages.

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.

Upgrade OBS crash to current upstream latest release Base version is the one before current upstream with many of the upstream current

Customers may face problems with their systems we weren't aware of, if we focus on testing single components. We simply can't copy each and every customer setup, but we want to have test results that are more relevant.

Description: Libiscsi:

In ubuntu, you can install grub-ipxe, which adds an ipxe entry to the grub menu. This allows you to easily pxe boot on machines that may not natively support it. You can also use it along with grub2-reboot to remotely re-image a machine. The project has been started here: https://build.opensuse.org/project/show/home:blarson:grub-ipxe It needs to be tested, and polished before trying to include it into opensuse.

Since a few months it is now possible to build an upstream QEMU which includes only our supported VCPU accelerator.

Project Description

The Robot Operating System (ROS) is a set of software libraries and tools for building robot applications. From drivers and state-of-the-art algorithms to powerful developer tools, ROS has the open source tools you need for your next robotics project.

Examining vmcore with crash (very) often means to look at multiple outputs at once, which in console enviroment simply is not easily achievable. Since last hackweek, there is a

While packaging node.js modules, which often depend on specific versions of other node.js modules, sometimes many of them, you easily end up in dependency hell, and maintaining an OBS project with a few hundred of those modules can be a tedious task. So the idea for this project is to familiarise myself with how exactly dependencies are managed on package and repository level, check out what tools exist to drill into dependency data, and hack something that helps keeping OBS repositories in a dependency consistent state.

Running openATTIC and DeepSea on Multiple Distributions

Currently, As QA, we design matrix for the test cases, then use matrix to generate test cases' name, then according the test cases' name to add related settings, then add those cases' name and settings to the openQA test suite. I hope, we can design matrix first, then other steps will be generated by automatically.

Roughly follow a few selective chapters from the book 'Hands-On Machine Learning with Scikit-Learn and TensorFlow'

Project Description

Work on "nvme monitor" proposed command (see Resources).

Currently GCC relies only on the most generic alias analysis when attempting to track data in aggregates in interprocedural (IPA) optimizations. In the course of this project I plan to revive patches for using simple escape analysis to track all data which do not have their address escaped and use that information to track constants within them, analyze the impact on a number of benchmarks and submit them to GCC trunk.

Create a JUnit test suite for Firefox browser and integrate the tests into SLEnkins.

Project Description

HAKube UI plugin for Rancher

The CRUSH algorithm determines how to store and retrieve data by computing data storage locations. CRUSH empowers Ceph clients to communicate with OSDs directly rather than through a centralized server or broker. With an algorithmically determined method of storing and retrieving data, Ceph avoids a single point of failure, a performance bottleneck, and a physical limit to its scalability. CRUSH requires a map of your cluster, and uses the CRUSH map to pseudo-randomly store and retrieve data in OSDs with a uniform distribution of data across the cluster. This project aims at creating graphs of the crush map, for better visualization of the Ceph cluster.

Translations get more and more important in packages live. Currently, translation-update-upstream is the only tool capable to update packages translation. It was designed 10 years ago. It is a hard to use monolithic tool that does not use advantages of openSUSE Build Service.

Project Description

The idea is to create a DIY throttle quadrant for flight simulators like MSFS or X-plane.

Building on top of <a href="http://rdimitrov.twistedsanity.net/blog/show.php?entry=Microcontroller%20Class%20D%20Amplifier,%20Rev2&quot;&gt;Rouslan Dimitrov's Microcontroller Class D Amplifier</a>, I developed the idea to feed the power amplifier with PCM data directly. Rouslan does some dithering and noise shaping, but I'm convinced that proper interpolation would sound better. The ATtiny is too slow to do even cubic interpolation so I'll move that into the host.

I have my favorite card game from childhood . Unfortunately description is available only in Russian https://uk.wikipedia.org/wiki/%D0%94%D0%B5%D0%B1%D0%B5%D1%80%D1%86%D1%8C . Currently my friends spreed across the globe and here in Germany no one except my wife knows the rules . I would like to to have ability to play this game with my friends like I did in school/univercity.

If you are now thinking of Salt-SSH, this is not completely wrong, but also not right. What we are talking about here, is an other Transport for Salt, a replacement for ZeroMQ.

Why?

In our team, we currently manually deploy our Terraform code (namely, the SUSE Registry at registry.suse.com) from our own PCs. This is error prone, as it would be very easy to override something by mistake. I want to create the appropriate .gitlab-ci.yml file that will:

This project aims to run VMs in a CaaSP 4 cluster using kubevirt and a libvirt+qemu container (aka compute container) based on SLES15 SP1/2. Compute containers based on openSUSE Leap15.1 and SLES15 SP1 already available in registry.opensuse.org and registry.suse.com respectively. VMs can be deployed to the cluster but there are several functional problems that need investigating, e.g. accessing the VM's serial and VNC consoles, proper network access, etc.

Starting with CUPS 1.6 things have changed considerably. Clients are no longer discovering broadcasted printers anymore. Distributions (e.g. Debian) has backported the original protocol into cups-daemon package but this doesn't seem to work either on my laptop. I would like to look and try to understand what the hack is going on here. The outcome should be my understanding of the change and how to configure CUPs to behave reasonably again.
