I'v been doing the testing on device mapper, once there are some regression it's very hard to debug without block-layer knowledge.
I'm very interest on how the kernel handle the bio/request/request queue/elevator system.I think this is good chance to read and learn .

Minion, the job queue of the Mojolicious web framework, currently has to be administrated with command line tools. I want to build an Admin UI that will make the most common maintenance tasks, such as restarting a large number of failed jobs, a lot more comfortable.

Hackweek 17

free hugs for hackweek

While I despise Trello, I quite like the idea of using a Kanban board to organise my individual work and much of my personal projects So if I have time during Hackweek I plan on looking at https://wekan.github.io/ also

Results: * https://ikapelyukhin.github.io/

need to learn more about containers

motivation

I like light weight presentation frameworks based on plain text files. There are quite some frameworks using the browser for presenting but many require a full blown web server. remark seems to be about the lightest I could find. I could make actual use of it when there would be openSUSE(/SUSE) branding.

moin, i am looking for interesting articles that describe how to refactor/maintain golang code. At moment i found this.

Introduction

TensorFlow™ is an open-source software library for Machine Intelligence written on Python. It was originally developed by researchers and engineers working on the Google Brain Team within Google's Machine Intelligence research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well. (https://www.tensorflow.org/)

I will deploy a k8s clusters on three pine64 A+ boards, all boards are installed opensuse tumbleweed, and one as k8s-master two as k8s-minions. The whole cluster will use TLS and BRAC security mechanism.

Setup an iscsi server on minnowboard/espressobin/odroid c2 based on opensuse tumbleweed, use two Nics to support multipath Setup an iscsi initiator on odroid c2 and dm

The the LUKS UUID in /etc/crypttab. In general the file system UUID is already used in /etc/fstab. So using the LUKS UUID in /etc/crypttab is a small step towards consistency and should make the system more robust (e.g. avoid bugs like bsc #1063249).

The ZSTD is a new compression method, potential replacement for existing methods. The support has been added to linux 4.14, but the bootloader support is missing. Goals:

Build Stages

Travis-ci.org currently has nice beta features that I've wanted to try for a [long while(#https://travis-ci.org/foursixnine/openQA/builds/280652163)...

To be able to offer real Tumbleweed and a tested Leap for a Raspberry Pi3 the images for it need to be tested with openQA. Since

During my trip to and from SUSECon 2017 I had been working on a pinctrl driver for Actions Semi S500, based on a previous pinctrl driver of mine for Realtek RTD1295. Goal of this project is to complete the driver with pin definitions and muxes.

In os-autoinst and installation/bootloader_svirt.pm we currently we support only one-disk scenarios like SLES installation to disk and deployment from a disk in JeOS & CaaSP scenarios. To support RAID tests we need support of adding multiple disks to VMs. Targeting Xen and Hyper-V.

Try various container operating systems & kubernetes distributions and compare them to SUSE MicroOS and CaaSP, respectively.

In lieu of official hosting which was requested a year ago, go ahead and refactor approach to work on AWS S3. The previous approaches used either soft or hard links to avoid duplicating files that remain unchanged between snapshots, but S3 is not a file-system and does not support links. The closest comparable concept are object level redirects, but managing and creating those would be combersome, slow, and result in a higher bill. To avoid that an alternative that does not require object level redirects to simulate links, but that does not requiring duplicating files would be preferable. In addition the tool built to provide such snapshots on S3 should be easily deployable and setup to run automatically on AWS.

Planning to do some deep learning course sessions e.g. fastai , google ML crash course etc. Also try to understand common tools (tensorflow, jupyter notebook, numpy, pandas, pytorch) and practices e.g. Convoluation neutral nets, SGD used to solve learning problems. Aim is to get ready for kaggle competition (https://www.kaggle.com/competitions) eventually to test out learning and develop intuition around categories of learning problems.

About 3 years ago I wrote some Python and Kivy code for my Samsung Galaxy S4 in QPython. Unfortunately, QPython updated and broke its kivy compatibility. I've been waiting for them to fix it, but mostly have given up. So instead, just investigate how to turn the kivy code into an .apk for installation on an Android device! There are directions for this on the kivy website.

What is kompose? kompose is a tool to help users who are familiar with docker-compose move to Kubernetes. kompose takes a Docker Compose file and translates it into Kubernetes resources.

Explore the GraphQl (v4) GitHub Api and do a small project in (Elixir would be the choice)

Starting from prometheus ( and grafana if needed), learn how to monitor kubernetes and docker and do some valid alert/graph etc. https://docs.docker.com/config/thirdparty/prometheus/

Description

Experiment with and implement a server (openSUSE Kubic, SUSE CaaSP) with connected thin clients (Raspberry Pi) that executes GUI applications from docker containers running on the server.

Mental poker is a principle and also specific protocol to play card games without a single trusted party. This includes shuffling cards, enforcing card visibility and commitment schemes. Imagine playing rock-paper-scissors via phone only. libTMCG is an implementation of the protocol and SecureSkat is an application of this protocol/library to the popular German card game Skat.

The usual baby-phones and phone based surveillance solutions do not fit my needs: - We live in townhouse with reinforced concrete walls (the signal from the babyphone is not strong enough)

2018

new hack

motivation

Lots of crucial steps in the SUSE/openSUSE product build workflow are not known or not even accessible by many people but hidden as "custom scripts" on "some machine" in the worst cases. Nowadays infrastructure and build pipelines should be written as code, e.g. in git repos, with UI frontends to show the always current state of what is going on, what needs to be done to release products, where are problems. The least we can do is learn a bit more in this direction.

Currently helpers for maintenance of SLE/openSUSE such as osc omg exist just as git repo, lets have them as packages.

The openSUSE.org official infrastructure is getting bigger and complicateder, so #microservices and #serverless FTW! :smiley: :thumbsup: :icecream:

Glowing Nixie Clock * A Nixie tube (English: /ˈnɪk.siː/ NIK-see), or cold cathode display, is an electronic device for displaying numerals or other information using glow discharge.

All our packages have a *.changes file and ideally that file would mention relevant changes from upstream, i.e. during version updates. Currently, we find that information manually when packaging Haskell software. This is unsatisfactory because of the sheer size of the package set and the massive number of updates we receive from Hackage. The packaging itself is completely automatic, but editing the *.changes files is not and this issue prevents us from shipping more packages in Tumbleweed and elsewhere. Now, during this Hackweek I'd like to write code that given two Haskell package versions old and new can determine the upstream changelog entries between those two and create a pleasantly formatted entry for the *.changes file that won't need any manual editing to pass the review team. Then I'd like to integrate this into cabal2obs, or maybe even cabal2spec.

In day to day job I often wait for openQA job to change a state. I plan to create chrome plugin which would allow to watch for some certain job and will send you notification when run is end.

I need to get a basic understanding about MD software RAID setup only via command line tools to be able to understand,

Explore the possibility to have a self sufficient frontend server running locally. This server would compile all the frontend code and act as a proxy/middleware pointing either for a dev ref-server or to a local SUMA instance. This way would be possible to do modifications in frontend even without having a SUMA server running locally. http://imagebin.suse.de/2542/img

Some ideas from the list: Small ones:

What is it about? I write lots of notes, about almost everything. Writing is a very important part of my work and of my organization in general.

git-deps and hatop deserve some more native packaging love. let's improve this and make a good package for multiple distros when possible.

SSO for kanku

As we use kanku for testing/debugging our OBS Appliance images.

I want to connect to matrix.org via weechat in Leap 15.0. 1. I need the matrix script

I want to improve myself in Perl & Mojolicious and I want to have a nice open-source self-hosted message board / forum written in Perl. Let's combined it into one ultimate goal. I would like to have:

Background

Candidates

For testing some of the upstream Linux drivers we maintain it is necessary to emulate the hardware as we're getting bug reports for the upstream drivers but have no chance to test fixes. Once the upstream drivers can be emulated we could focus on emulating hardware where only downstream drivers do exist and then write new drivers to be upstreamed.

Every time we went to UEFI Plugfest, one of the frequently asked questions is how to setup a PXE/HTTPBoot server. Besides, we also have to setup and test the server before the event. Although we already have the document(*), it may be easier to deploy with a container image. My goal is to learn how to package a container image in SLE/openSUSE and create a flexible image for the fast deployment of PXE/HTTPBoot server.

I want to dive deeper into React using its Material-UI components to prototype a web interface for SUSE's new Repository Mirroring Tool (RMT). Updates:

Leap 15 and TW supports Transactional Server system role but some additional work is needed to have a transactional desktop system role. The purpose of this hackweek is to document what need to be fixed and try to fix it.

We provide tftp server and RPMs containing the installer to run from tftp. Disadvantage is, that the user needs to setup a tftp boot system first. Why not putting everything in a container, so that the admin only need to run the container and can then choose on the to be installed machine, what he wants install? And following this, put the container in a kubernetes cluster like SUSE CaaS Platform.

Signing metadata requires a lot of manual interaction and knowledge of the customer. This was the reason why we never implemented it for SUMA as the benefit was very low. Now with the change in the zypp stack to not allow installing unsigned RPMs without user interaction or completly disabling GPG checks the benefit of such a feature increased.

Build a smart thermostat using an Adafruit Feather HUZZAH ESP8266 board, a DHT22 temperature and humidity sensor and a 2.4 TFT touch panel. The requirements are:

(was: Create a DRM driver for Matrox G200) Even after 20 years, the Matrox G200 series is still an excellent 2d graphics card. Unfortunately, there's only an fbdev driver and a user-space driver. Both are obsolete, as modern Linux uses the DRM framework for managing graphics cards. There already is a DRM driver for the G200 server series. This driver is under-maintained and doesn't work with desktop chips.

Update

Working on the documentation...

This nowadays is a supported HANA Scenario that has no much knowledge and documentation around. This project is basically to explore what we currently have, and maybe document some initial good practices around SAP HANA Scale-out to facilitate future developments and also our current supports.

To make it easier to debug openQA and Cavil i want to build a plugin similar to the mod_status Apache module for the Mojolicious web framework. Figuring out how to combine HTTP and WebSockets should be interesting. If time permits i also want to make it look a little bit like the Minion Admin UI from my last HackWeek project.

I bought and started reading this book a little while back and also "played along" by creating unprivileged LXC containers on my own system. I would like to continue this exploration by reading on in the book and creating, configuring, managing, destroying... further containers.

Motivation

GPUs are widely used for parallel computations and CUDA is platform which simplifies development of such applications for NVidia GPUs.

First thing you learn, when you start with salt, is to use test=True before you really call the highstate. This is not yet possible from the SUSE Manager UI.

Add some features to libstorage-ng. - Support for F2FS

I'd like to write a tool that reports user's OBS work done in a given time frame (eg. week). It'll collect all the packages he/she submitted, all the reviews done or all the maintenance updates started or processed.

For every instance of OBS, each time the obs-api package is updated the obsapidelayed service is reloaded. This takes more time than is expected. Task to be done are:

** UPDATE ** After a week of hard but passionate work we have managed to finish the first version of The SUSE Game with a surprising final!

I currently have a lot of personal infrastructure that is in need of some tender loving care and transactionalisation https://rootco.de is running on a Leap 42.3 Hetzner box. I'd like to replace this with something transactional (either Kubic, Leap 15 or Tumbleweed transactional server)

• Check packages that I maintain or are in devel projects that where I am maintainer and update them.
• Check bugzilla for issues filled for said packages

The goal of this project is to get an overview of the state-of-the-art technology on training and deploying machine learning projects with kubernetes and apply that to a SUSE CaaSP cluster. With that in mind, we will train and deploy a model for summarizing github issues:

SUSE Quiet is an acoustic version of SUSE Loud, the former SUSE Band from Maxtorhof. We will be making our debut on Thursday evening at the Hackweek Party.

I'll have a look at Hyper-V 2019 test build and how SLES guest plays with it.

I plan to learn Go, first by going through the official 'Tour of Go', then implementing simple caldav client to help me with work reports.

The vacuum cleaner from Ecovacs use XMPP (or at least something very similar to it) to communicate with their respective mobile apps. Based on the things available in https://github.com/wpietri/sucks and https://github.com/torbjornaxelsson/bumper I'd like to implement a small replacement for the server side to be able to run that on my local server.

Deploy openSUSE Leap 15.0 image to Linux subsystem on Windows Server 2019 and try things around.

Docker for Windows 18.03 CE supports Linux containers on Windows Server. Let's try that.

There are a lot of open source projects out there. They have a wide spectrum of governance models. It's a critical component to the success of a project so it's worth learning from others and consciously deciding on how governance is set up for a project. It's also a critical factor to assess projects and a subject for research. To facilitate all this a map of the models in use is a helpful resource. This project is about collecting data about open source governance models, make it available in a machine-readable form, and provide an overview via a web page.

Monasca is a powerful tool in the OpenStack arsenal. It brings metrics and alarms to the operator. It even pairs grafana with horizon. It currently monitors Swift, but just the processes. But there is so much more we can grab. Swift actually generates heaps of metrics. For one It has supported sending metrics via statsd for years. All the internal daemons send statsd. Further, built into each server is a reconnaissance API (recon), that you can hit over REST or by using the swift-recon tool. Swift operators have been using these for years.

SmartOS is converged container and virtual machine hypervisor based on illumos, an OpenSolaris fork. SmartOS supports KVM & bhyve hypervisors and illumos, LX, & Docker zones ("containers"). There are LX-branded openSUSE & SLES images unofficial. LX-brand is implementation of Linux API on SmartOS (similar to Microsoft's Windows subsystem for Linux).

Matrix (https://matrix.org/blog/home/ ) is a slack / rocket-chat clone, fully decentralized. It supports a lot of clients and bridges to various networks, including IRC.

The most important task for my first hackweek - accessibility of the Gnome Shell. There's the project called gnome-shell-mousewheel-zoom - not maintained for 6 years.

Let's see how correctly the FreeBSD emulation layer works.

When using files that should be in an accessible file system, quite often I have been in a situation where * I couldn't find a document by name but remembered attributes like 'document' (unclear which format) with '> 12 pages' and dates from '2011 - 2015'

SUSE Studio was shut down earlier this year. It has been online for more than ten years and there are tons of links and references out there. To not make them lead into the wasteland of 404 we should have a landing page on https://susestudio.com which leads to what users can use instead of SUSE Studio. I did a mockup of a page which could be hosted there. See it at https://github.com/cornelius/goodbye-dister.

Synopsis

JRuby is an implementation of Ruby on the JVM. It aims to be a complete, correct and fast implementation of Ruby, at the same time as providing powerful new features such as concurrency without a global-interpreter-lock, true parallelism, and tight integration to the Java language to allow you to use Java classes in your Ruby program and to allow JRuby to be embedded into a Java application.

Update: Ruqola ('zypper in ruqola') is now in Tumbleweed and Leap 15.2! For Hack Week 19 (Feb 2020) main goal is to test, polish packaging, potentially do fixes and select a snapshot to submit to openSUSE Tumbleweed. Upstream made one release but it was not optimal, development pace has sped up a lot lately and the client has become more stable and usable.

I want to learn more about robotics. The goal is to have a small robot at the end of the week. Since I have no clue of what I can do with robotics / what is possible I leave it open what the

SUSE Manager uses an ivy repository on the R&D network to get the packaged jar to build against. To remove the manual maintenance of that repository and allow external contributors to hack the Java code of Uyuni / SUSE Manager we need to provide an Ivy plugin that gets the jars directly from OBS.

I have previously implemented a major portion of the C++ standard library for HelenOS [0][1][2] as part of my master thesis. In this project, I will be adding

I plan to work on libgphoto2 Lumix WiFi support. Status after Hackweek:

The Parrot seems to have many fans meanwhile, in particular since we're running Rocket.chat at SUSE. Some may find these emoticons distracting, some find it just cool and I would certainly love to see something like the Partyparrot but as a "SUSE parrot", probably someone manages to make the SUSE Geeko move in a similar fashion, as party_geeko. Finally I'd love to see this uploaded to the cultofthepartyparrot.com under "Party Guests". Because clearly the Geeko insists! :-) Bonus: do the same with TUX for total ssǝuızɐɹɔ

The idea is to look at some technologies: - C++17 parallel execution

Use mouse to select a word on the screen, popup a small icon, click icon, then show a window to display word online translation result.

motivation

Many people ask how to start with openQA, ask "can you run these two lines in bash in an openQA" test and some shun the effort to try out openQA because it is "too big".

We are running the geekos app at geekos.prv.suse.net since some time now in the SCC CaaSP cluster. The goal we have is to bring this to production in the CaaSP cluster maintained by the engineering infrastructure team.

Description

On aarch64, ppc64le and x86_64, there is a common os-autoinst backend called qemu, in which qemu is launched from an installed SLE.

LanguageTool is a style and grammar checker for 25+ languages https://languagetool.org Packaging it will require packaging the following maven packages and their dependencies:

Given that free time is always a scarce resource, I'd like to use the hack week to work on v2.0 for OTPClient Github project: https://github.com/paolostivanin/OTPClient/projects/4

During the previous Hackweek I did a workshop in a Montessori school. This time I would like the same but with focusing on Robotics. Who is this for?

I would like to convert a very cheap foam toy plane into a radio control plane Materials

In order to see the SPD (detailed memory information) data, the user currently has to manually load the needed kernel driver. Which driver to load depends on the memory type. Depending on the driver user, the devices may even have to be instantiated manually and this is a non-trivial multi-step task. Plus you need to be root to do it. I would like to attempt to automatize all this at least in the most common and simple cases like Intel x86 desktop. The idea would be to figure out the memory type and the I2C address of the SPD EEPROMs based on DMI data. If the DMI data is of good quality then it should be possible to automatically figure out which driver to use and to instantiate the devices at boot time.

Produce a ~3 min demoscene using modern javascript libraries combining graphics with original music.

The youngest architecture addition to the mainline Linux kernel was C-Sky (arch/csky/). I have a GX6605S board booting a downstream 4.9 kernel. It uses a proprietary GxLoader bootloader (similarities with U-Boot exist but no sources...) with uImage and gx6605s.dtb files in a FAT partition on USB stick.

I maintain the mailprocessing utility, a Turing complete maildir and IMAP capable filter with rules written in Python, both upstream and in openSUSE. It is currently suffering from some performance problems I'll devote my Hackweek (or part of it) to improving. Most notably the following areas will need some attention: * Ability to deal with large inboxes. This one is already done and I have been using it myself for a while but not released, yet. If you urgently need it feel free to grab it from the master branch. I'll give it another once-over before release, but it should be fine.
