Video Recording of openSUSE Conference session which introduced the project

New Development

Join us in singing a capella — barbershop-style and others. Find us on RocketChat: #chameleon-harmonists

This is the tool I've been working on since HW11 and it needs more work. Actually, there's always something which could be done on it. It is basically an x86 instruction decoder with special emphasis on the kernel and decoding interesting pieces of it in order to help in the development of low-level patching techniques, among others.

Description

It can boot up from udisk/floppy.

RPMlint upstream milestone 2.0 is shaping up but there are still ticket that needs to be tackled to finalize the release and enjoy the freshness of awesome QA on Tumbleweed/SLE16.

1.Test to burn the opensuse kernel on Raspberry Pi and make it working. 2. Try to use Raspberry Pi to control some sensors.

PXEAT (stand for PXE Administration Tool) is a tool to easily deploy and manage PXE service.

The YES Certification Tool Kit has long needed Video Tutorials for clean step-by-step tool usage and configuration. These will be done with video screen scrapes and audio overlay.

RISC-V is an open ISA (Instruction Set Architecture) based on RISC architecture. It's originated from UC Berkeley and it's attracting more attention in recent years because of its full open architecture so every developer has opportunities to get involved in application processor design or apply it into different applications, such as IoT, Robotics, ... etc.

We kinda need more flexible PXE in Prague office, UEFI would also not hurt - so lets check what we can do to make it better.

We already tried to improve the Jangouts data model in the past and, although we made quite some progress, we did not finish it. I've been playing a bit with React and Redux lately, and I would like now to try a different approach replacing Angular with that combo. Using Vue.js might be another option too.

The goal of this project is two fold.

Circuits is a coding marathon to challenge developers with several programming questions of varying difficulty level over 9 days.

Make a final attempt to implement a graphical user interface for grub2 (gfxboot2).

The idea is about an easy way to allow users to make upgrades (e.g.: changing from one major version like 15.0 to version 15.1) using a GUI and as easy as they can in Ubuntu.

I've attempted this several times already and each attempt had different shortcomings. I'm kind of curious about how exactly will I fail this time.

Inspired by Corebird, I'd like to write a native GTK+ Weibo application for Linux, so that I can learn how to write a GTK+ application from scratch, and every Weibo users can benefit from it.

Out of nowhere the idea came up to organize a rum tasting session on one of the HackWeek evenings.

It's clear that in Kubernetes world, SUSE and openSUSE chose Cilium as the main network provider, which also means choosing BPF and XDP as underlying technologies for implementing datapath and packet filtering.

This is to provide partners with video tutorials to help with the certification of their SES and SOC cluster solutions. The goal is to simplify the setup process in order to provide a better experience for the partner. If we can alleviate some of the stress of setting up a cluster more partners will certify their solutions.

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

Ceph offers a highly scalable and fault-tolerant storage system. Samba is already capable of sharing data located on the Ceph Filesystem, however scale-out sharing (the same data exposed by multiple Samba nodes) currently requires the use of CTDB for consistent and coherent state across Samba cluster nodes. In such a setup CTDB provides a clustered database with persistent key-value data storage and locking. Database usage is abstracted out via a generic dbwrap interface.

My previous knowledge about Python is small. I need learn more about python.

The goal is to create a set of YAML files describing L3 supported products with all metadata we need to store there - and a JS presentation layer automatically showing this data in several forms, one of them will be a part of our L3 documentation.

Flickr provides not only a large space for photos but also nice features around, including tags and other metadata allowing sorting of photos by different criteria - but one is very limited in the design of something like "frontpage" of such galleries. The solution is to use 3rd party JS solutions using Flickr API, like nanogallery.

There seems to be an overall consensus that the ioctl interface used by ethtool is a poor design as it's inflexible, error prone and notoriously hard to extend. It should clearly be replaced by netlink and obsoleted. Unfortunately not much actual work has been done in that direction until this project started.

I would like to dedicate my time to the improvement of the Czech localization of KF5.

Ai and Machine learning play important role in our life, I'd like to learn it.

Hackweek 18 Update

Mottainai - Task/Job/Build Server for everyone!

I have been known to talk anybody I held presentations with into using odpdown.

What is meCoffee?

The idea is to explore the technologies and the various components to realize some AI to predict pitfalls in source code which can potentially generate run-time misbehaviours.

To ease debugging cgroup relates issues this suggests to:

The experience while navigating throughout the UI of Suse Manager it's not that nice. Whenever we navigate to a new page, the whole page gets refreshed and recreated, even when half of it didn't change a thing, for instance, the menu, topbar, and the notifications WebSocket connection, which in my opinion doesn't provide a smooth experience.

QLogo is a UCBLogo-compatible implementation of the Logo language using Qt and OpenGL. QLogo was designed with the language interpreter integrated into the GUI.

The state of the art of sysv/posix ipc benchmarking is a combination of ad-hoc programs scattered over the internet. While some mechanisms, such as sysv semaphores, have a lot of coverage, others really lack (message queues), and some are simply non-existent; albeit some of the legacy flavors we aren't too concerned with, other than them being functionally correct.

There are various email synchronization programs like offlineimap or mbsync, which have some inherent limitations:

Let's make reposync faster

During the last year Askbot, a question and answer oriented internet tool, similar to stack overflow has been tested for internal usage.

Currently the CPU subsystem of Collectl can get the CPU loading but no CPU power state. My idea is that tracing turbostat then developing a collectl module to get the CPU power state. It can be used to monitor C-state or frequency.

As there is no progress around MIrrorPinky since 5 years now, let's say the project is dead and look for something different, which allows Mirror administrators to edit the settings of their own mirrors.

I have noticed that explaining HA cluster concepts to non technical people is not easy (my parents for example hehe). In order to improve that I would like to create a more visual project using raspberry pi-s.

Hackweek 21?

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

It's been a little while since I last needed to do some binary reverse engineering, so I want to up my game.

I just recently started a new project which is meant to be a wrapper for OBS's API. The library is written in Ruby.

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.

Pi Security

A common challenge for OpenStack and K8S deployments is debugging the network when things go awry. The aim of DPHAT is to provide operators of cloud infrastructure with tooling that can analyze the environment and supply the following:

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:

The salt-toaster (https://github.com/openSUSE/salt-toaster) is a tool created and developed by SUSE employees that we've been using for testing Salt since few years ago.

At SUSE we've implemented a module on Salt called ansiblegate which allows to run and manage your Ansible clusters using Salt.

Currently, way we distribute ssh keys within QAM on our testing infrustructure is a bit cumbersome - maybe we should try to (ab)use existing salt used by our internal infra team.

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.

Metal³ is the idea to support a declarative bare metal cluster management for Kubernates by employing a simplified stand alone version of Ironic.

A filter to scramble writing actions to a stream randomly into multiple sequential actions, aiming to provide some protection against deep packet inspection, implemented in the form of an OpenSSL filter BIO.

INSTRUCTION: A remote reminder connected this server with WIFI module(Maybe not just a reminder ).

Since my mailbox has migrated to office365 mailbox a couple of weeks ago, I tried to optimize my tool chain to sync my mail and calendar and integrate to the gnome-shell (calendar, notification). So far I am comfortable with such a set and gonna use 2-3 hours in hackweek to summarize the practice of combining the following tools in written format:

It ain't rocket science, it ain't thrilling, it's just useful.

The idea is simple - I want to learn Python :) My previous knowledge about Python is small. Only few tutorials and some initial readings of below mentioned books to get an overview.

https://mycroft.ai/

As a daily user of the Plasma desktop this Hackweek is a perfect opportunity to make my first contribution(s) to it! Feel free to join me as a fellow beginner or mentor!

I recently bought a 3D printer (ender 5) and would like to expand on my foundational knowledge on the topic:

Description

I want to get an openSUSE based image working on Samsung DEX:

1.Fetch useful/popular item from SMZDM 2.Build web server

Trimatik MC is an older heating control from Viessmann. It has no supported digital interface for remote access, but I found at least two ways to get access to sensor data like various temperatures and state of relay contacts. One way is to use the so called remote control the other use the clock timer. This project will use the latter way, because the hardware adaption is much easier and and all four timer channels could be controlled as well. Remote access will be done via an ESP32, which emulates the clock timer and gets/pushes data via WIFI.

The current kplex_monitor repo needs to be reorganized so that it can be installed from scratch on another PI using ansible

[motivation]

What is Openspace? Starting on Kickstarter and Indiegogo as Openbook Open Source Social Networking Service got recently renamed to Openspace (still reachable via openbook.social though). This network wants to protect its users privacy and make the world of SNS a better place.

Rationale:

The current GUI of FriCAS is ancient and difficult to use. I plan to improve that by using modern GUI frameworks, at least to make a working proof-of-concept demo to show this idea works.

In-depth understanding of how ptrace works; get the implementation mechanism of ptrace;

Minnowboard is the platform for UEFI development and supports UEFI capsule update since 0.99, and we are supposed to be able to test the feature with fwupd. However, there is no capsule file in fwupd.org or the official firmware download site. Besides, the Minnowboard firmware source in the current edk2/edk2-platforms git couldn't build due to the recent change of directories. My goal is to rebase the Minnowboard build system to the current git master and create a working up-to-date firmware. Signing the firmware properly would be a plus so that we can apply a private repo in fwupd.org for the development or QA testing.

Try to use apache-rex framework while testing httpd modules.

What I do: learn the virtualization knowledge, get familiar with various ways to migrate guest, know the user's normal scenarios and requirement. Goals: give an introduction or a summary to share, including text and graphics about virtualization and guest migration.

Rationale:

A lot of openSUSE bugs are filed with plenty details but without a specific assignee so often many days are lost between filing and a developer seeing the report.

I have build a table for our RPG sessions (DSA/Deadlands/Paranoia) which incorporates a large 24" LCD Display for showing maps during the sessions.

Instruction

As a Caasp developer, I need to learn GO language. While I have an opportunity to learn GO language during HeckWeek,

Brief

I've been doing a terrible job of maintaining GNU Stow the last year, and there's quite a backlog of bugs, feature requests, support requests etc. So it's a good time to catch up on these.

Check if it is possible to create a python application to aid autofocus micro adjustment on a DSLR. There are some commercial applications that are capable of that, such as Reikan FoCal (https://www.reikanfocal.com).

Inspired by a conference talk I've attended a while ago (and my own struggles when trying to create something pretty basic just recently) I want to learn more about SVGs in general and their powers for modern web development in particular.

Sorbet is a gradual type checker for Ruby.

Milkytracker is a free software multi-platform music tracker for composing music in the MOD and XM module file formats.

A few years ago I wrote the "worst 3D Printer". Basically, it takes a 3D model (VRML) and slices it to bitmaps, which can be arranged on paper and printed, then manually cut out and glued together. As you can imagine, just doing a small print could take 500 layers, so it could take a day to assemble (hence "worst"). [1]

Brewtarget is an open source brewing software, similar to the commercial product BeerSmith. For hackweek I'd like to investigate the capabilities of Brewtarget and perhaps add some features/improvements for my use case.

Following a FOSDEM presentation on Angr for binary analysis, I started packaging it in OBS.

The Goal is...

Well the see of openSUSE Infrastructure has been unrest and need our attention. I would like to invite you for this cruise trip.

...because openQA isn't going anywhere anytime soon.

I want to be able to create some 3D printing models for 3D printers. So starting to search for a good introduction and try it out...

The monitoring in our internal infrastructure needs some love and attention. I want to spent some time during this hack week on the monitoring by fixing old checks, implementing new checks and making sure that those are configured and installed via configuration management.

Stream Radio device - It is built with Raspberry Pi Zero WH

Goal is to implement a rados backend in drivers/nvme/target. That will allow the NVMe target implementation to directly access Rados objects (ie export RADOS objects as namespaces), allowing third-party applications and/or OS to use NVMe-over-Fabrics to access a ceph cluster.

or how to replace git push heroku master and cf push with Kubernetes

What is ResourceSpace

This can be seen as a subproject of ethtool netlink interface but from the technical view it's independent.

As the automation became a standard within Maintenance QA work, I would like to became more familiar with the whole magic behind. Plan is to go through internal docu a try to setup openQA and write some simple tests (and adjust the docu once there are any gaps):

This is my attempt to catch up on the field of machine learning. In order to not "waste" time of exercising with dummy data the Security team came up with a couple of interesting questions:

I use my Raspberry Pi 3B as a router. I have seen this crash:

The day has come to finally merge more and more apps into one single place, and this time it shall be externaltools.

Since quite a while I'm interested in learning the programming language golang. I want to use the time to get a basic understanding and maybe realize a small project with the gained knowledge.

QDirStat in General

Learn Go language by through The Go Programming Language book.

This is a side project I started a while ago. The idea is to implement a tagging engine with some "advanced" features for the Django web framework (in what Django calls a "reusable app").

People are interested in Linux on Windows via WSL, especially given the new fully virtualized Linux kernel in WSL 2. It's interesting to know whether registered SUSE installations might be running in WSL as opposed to other Microsoft virtualization platforms, but the current approach taken by SUSEConnect (the client for SUSE Customer Center) does not permit this.

In the other day, there were questions about to migrate high availability solution into OpenStack.

Short-term:

1. Understanding of docker knowledge

The goal of this project is to create video tutorial describing configuration of SUSE Manager for Retail.

The plan is to implement a safe path resolution library for Linux to avoid the plentiful numbers of security vulnerabilities that have been seen in the wild related to path resolution race conditions and various other attacks. I've been working on kernel-space solutions but even if they were merged, it is difficult to use them safely directly. So this library intends to provide simple wrappers that everyone can use.

My music manager, Bard, was improved in the last hackweek with a very simple React-based web interface but I didn't like the result at all (basically, after learning React I noticed I didn't like it and all the dependencies and the complexity it added) so since then, I've reimplemented the web interface using just jQuery. Also, in the last months I've added musicbrainz data structures to the database (which was also ported to use Postgresql) to prepare bard to use MusicBrainz's data. I also stopped using other python libraries to read audio files and use the ffmpeg libraries directly instead with a c++ wrapper implemented inside Bard which is much much faster.

Currently it's pretty difficult to create tests for some specific package. So something like TravisCI for OBS would be good.

My goal is build on Alberto's work on "yomi" and the new Salt-based virtualization management features that Cedric has contributed, then combine them with a Redfish prototype to do the following from one (ideally idempotent) Salt state (orchestration state if required):

https://github.com/dmulder/phylogen

This is a task to update current WSL-Launcher (which can be already buildt in OBS) with latest-greatest upstream code https://github.com/Microsoft/WSL-DistroLauncher

Having done only very little with openQA in the past I would like to learn more about it. I would like to start writing a test suite for profanity.
