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.

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

[motivation] - When we have clear idea to do something we could do month work in a week.

I want to get an openSUSE based image working on Samsung DEX: https://www.linuxondex.com/

Description

Play with raspberry pi to get high availability through load balancing and containers.

I recently bought a 3D printer (ender 5) and would like to expand on my foundational knowledge on the topic: * Learn 3D modeling with Fusion 360.

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. Current prototype is able is able to monitor traffic between the original clock timer and the heating control.

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!

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. Of course, we are not going to rewrite Jangouts in just one week, but let's see how far we can go. By the way, the redesign branch contains some interesting stuff from one of the GSoC that we should consider.

https://mycroft.ai/ Mycroft is the name of a suite of software and hardware tools that use natural language processing and machine learning to provide an open source voice assistant.

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: mutt, a small part of evolution process (for calendar sync), mailnag, mailnag gnome-shell-extension, tuning of gnome notification (understand the notification in full screen), trayicon plus.

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.

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

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.

It ain't rocket science, it ain't thrilling, it's just useful. Quick Event is an established orienteering management software but it is still distributed in non-standard form for Linux distros. Package the software in standard packages for major distributions.

The most relaxed testing framework of Kubernetes in the world

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

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.

We should explore if

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.

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. EDIT (ggherdovich):

Pi Security

I've ordered two security modules that can be used with the Raspberry Pi. One simple LetsTrust TPM with the Infineon Optiga SLB 9670 chip and a Zymbit Zymkey 4i Security Module.

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.

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. Any topic about RISC-V is welcome, here are some topics you might be interested in:

I just recently started a new project which is meant to be a wrapper for OBS's API. The library is written in Ruby. https://github.com/mschnitzer/open-build-service-api

At SUSE we've implemented a module on Salt called ansiblegate which allows to run and manage your Ansible clusters using Salt. This a very powerful module that bring lot of value to Salt when the users are planning on migrating or starting to use Salt and they already have an existing Ansible infrastructure.

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. This tool uses pytest in combination with Docker containers to allow testing the multiple versions of the Salt codebase and as well as Salt packages across multiple distributions.

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.

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: - Feedback that the environment is in a healthy operational state

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

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.

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

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.

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. The Fedora people developed a WebUI named mirrormanager for their admins - let's see if we can get it somehow connected to our MIrrorBrain database and use this as frontend instead.

Hackweek 21?

Postmaster desperately needs a mail spool. I need to come up with a good way to store meta information about queued messages. An sqlite database seems like a natural fit because I might want to do some nontrivial queries in there to figure out which messages to deliver (and where). On the other hand, interfacing with sqlite is a bit unpleasant, so instead I might want to write one big JSON file that contains all relevant information. That would certainly suffice for the first version ...

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. Reference: Collectl's HelloWorld module, turbostat

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. That's different from what we are doing in OpenStack. SUSE OpenStack Cloud provides mostly Open vSwitch DPDK as a network solution.

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.

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. Consolidate all this by taking the good benchmarks and implement new ones where needed, such as message queues, everything around the 'perf bench' framework. This will both improve the lives of us who hack on kenrel ipc as well as improve coverage overall. Eventually mmtests should be updated as well.

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. For Hackweek 18 I want to separate the interpreter from the GUI so that QLogo can be run from the command line or from a shell script.

To ease debugging cgroup relates issues this suggests to: - list cgroup hierarchy tree(s),

During the last year Askbot, a question and answer oriented internet tool, similar to stack overflow has been tested for internal usage. The testing went well and it was decided to use the tool in a larger scope.

Let's make reposync faster

Every day,

There are various email synchronization programs like offlineimap or mbsync, which have some inherent limitations: - mbsync does not support IMAP IDLE

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. The potential area where this idea could have positive implications are:

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. This project has the goal to test out an automatic way to transform the Suse Manager UI into a Single Page Application.

What is meCoffee? The meCoffee is a small PID that can be used to upgrade an Espresso machine with some new features. It supports mostly the Rancilio Silvia. The initiator of meCoffee is starting to Open Source his work and has already done so by opening up the meBarista application for Android, iOS and Chrome.

Out of nowhere the idea came up to organize a rum tasting session on one of the HackWeek evenings. There will be some information about the actual production of rum provided, as well as the different kind of rum existing.

I have been known to talk anybody I held presentations with into using odpdown. That was always a little awkward, since it started off with pip install odpdown, rather than zypper install odpdown. I want to fix this awkwardness and package odpdown properly so it can be installed as a RPM package. I'll also include the auxiliary infrastructure I've added around it over the years (various Makefiles and scripts for generating transcripts from comments) to the package so others can benefit from that stuff, too.

Ai and Machine learning play important role in our life, I'd like to learn it. research to see is there any way of using DEEP learning on open source stuff.

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. In this hackweek we plan to look on various problems as described at:

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. I've started to code for a while at spare time. You can find the project here.

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

Mottainai - Task/Job/Build Server for everyone!

Written in Golang. You can find the source code on GitHub and docs here.

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. The purpose of this project is to learn to create such galleries, the best would be to add social features of flickr directly there, like comments or faves.

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. Technology: HandleBars.js or similar, plus some YAML technology

Hackweek 18 Update

What Has Been Done During HackWeek 18

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. The project started in Hackweek 16 (fall 2017) and has been worked on since, both in Hackweek 17-19 and outside. First two parts of kernel implementation are in mainline since 5.6-rc1, first part of userspace implementation (ethtool utility) has been submitted to upstream at the end of Hackweek 19 (2020-02-16).

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. And it looks like I haven't failed this time.

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. Something like a notification with a button to perform the upgrade with just one-click, instead of having to deal with the terminal, that frights some new users and gives them the sensation of an outdated system.

Description

It can boot up from udisk/floppy.

PXEAT (stand for PXE Administration Tool) is a tool to easily deploy and manage PXE service. It's NOT a tool for automatic deployment. It can enable user to add their own PXE items by themselves, but of course, very limited for security reasons. The tool will be developed with the light-weight framework - flask, as well as a sqlite database.

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

It's quite some work, unfortunately. Here's what's done so far:

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. git repo: https://gitlab.suse.de/bp/x86d

New Development In previous hack weeks, the first few days ended up being wasted on just getting it working. I'm pleased to share that the code quality has improved dramatically since the last hack week and there are now extensive test cases for both unit testing and testing against real vmcores, and we'll use both mypy and pylint (if installed) to perform static analysis. Packages for those are available in openSUSE or as part of the crash-python OBS repo for SLE15. It has been tested with kernels from 3.0 to 5.1.
