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.

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.

Introduction

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.

Build Stages

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.

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.

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.

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?

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.

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!

Glowing Nixie Clock

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.

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.

Some ideas from the list:

What is it about?

git-deps and hatop deserve some more native packaging love.

SSO for kanku

I want to connect to matrix.org via weechat in Leap 15.0.

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.

Background

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.

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.

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).

Leap 15 and TW supports Transactional Server system role but some additional work is needed to have a transactional desktop system role.

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.

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.

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.

Add some features to libstorage-ng.

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.

** UPDATE **

I currently have a lot of personal infrastructure that is in need of some tender loving care and transactionalisation

• 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.

SUSE Quiet is an acoustic version of SUSE Loud, the former SUSE Band from Maxtorhof.

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.

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.

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").

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.

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!

I want to learn more about robotics. The goal is to have a small robot at the end of the week.

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.

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! :-)

The idea is to look at some technologies:

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.

Given that free time is always a scarce resource, I'd like to use the hack week to work on v2.0 for OTPClient

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

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

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.

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 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:
