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.

New Development

The idea is to create a bootable medium (eg. pendrive) that allows:

There is a running gag built into openQA called interactive mode. It goes like this: "if you need the interactive mode, it's broken". The reason: the so called interactive mode is a collection of hacks - in theory making it possible to update needles in a running test.

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.

The openSUSE build service could build hundreds of packages in parallel but in practice serial package dependencies prevent that.

To make OpenQA work with real ARM devices, we need to control

Dochazka is a long-term project to replace the obsolete Attendance & Time Tracking system used by the Prague office since 2007. Dochazka is a complex system consisting of three major components:

An introduction from minetest website: " Minetest is a near-infinite-world block sandbox game and a game engine, inspired by InfiniMiner, Minecraft, and the like. Minetest is available natively for Windows, OS X, GNU/Linux, Android, and FreeBSD. It is Free/Libre and Open Source Software, released under the LGPL 2.1 or later. "

Last time I checked QEMU lacked support for >= z10 processors. Thus one cannot run SLE12 and newer in a virtual machine on non-s390x host. I'd like to improve the situation during Hackweeks.

L3 bug reproduction often requires becoming the admin for a moment. I'd like to write down some nifty tricks I used to get certain “interesting” system configurations to work.

The Kubic Project currently produces a "CaaSP-like" Tumbleweed OS, focused on Kubernetes clusters

Matrix.org is a project to create a protocol and server implementation to replace IRC.

There are a couple of interesting initiatives that make the openSUSE project interesting for SMB, such as

1% of SUSE Manager's functionality in 0.1% of the lines of code

The idea is to create a fantastic robotic SUSE pet using cheap materials. It will be moved with you remote control of your TV. After building the prototype the schemes and Arduino code will be delivered for everyone to try building it at home.

Let's use the Hackweek to improve Ruby, the programming language I use every day. It is while using a language when you can realised that things that need/can to be improved, so there are many things that only Ruby developers can raise up. Also, getting involved in the development of Ruby will help to get a better understanding of how it works. So I will take my ideas/concerns to the Ruby community and implement some of the them in the code of the Ruby core.

Description

It can boot up from udisk/floppy.

Why

We started the SUSE Musician's Space several Hackweeks ago, out of which we spawned the SUSE band, now known as SUSE LOUD.

Python is well known all over the world and has wide range of usage. Lets dive into to a bit.

I want to create devel project for cryptocurrencies/mining tools/blockchain related stuff, fill it with packages and submit at least some of them to Tumbleweed.

2019

openSUSE Leap 42.3 goes for a rolling release model with automated openQA tests. That covers only so much though. We need manual testing too. In previous releases a google document spread sheet was used to coordinate and track the efforts.That's probably not the best method anymore.

TecnoAlarm is a house alarm system. The input devices are communicating with the main node of the system via an RS 485 bus. In order to be able to plug in such systems in a house automation system, its communication protocol needs to be reverse engineered.

We all pant for customer data. Which hardware do customers run ? Which packages are installed ? Which services are running ? etc. pp.

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.

Implement a basic file search for a given OBS project. An example of basic functionality can already be found for Ubuntu or Debian. The goal is to implement,

With all those analyzers for C code we get so much information about our C code.

In this hack week we want to focus on improving the existing components used for http://docsearch.nue.suse.com. Creating separated repositories for each service and pushing them to github.com is also desired.

I'm using Conversations (XMPP+OMEMO) as an encrypted IM solution. Since a lot of groups organizing them self using WhatsApp, it's hard to stay away from it.

retro-gtk is a toolkit for GTK+-based Libretro frontends. It is mainly used by GNOME Games to play retro games via Libretro gaming console emulators.

After an internal call for help to take over software.opensuse.org deployment, I spend some time studying the code in order to find out what would it mean to take it over.

There is a lot to do in the openSUSE infrastructure land...

Learn how openQA was implemented in details.

My current mail setup is mu4e and emacs based mail client included with the amazing mu mail indexer. mu works similar to notmuch but allows easy bidirectional operation with the original Maildir. Add mbsync (isync) to sync imap locally and msmtp and you have a full mail setup.

Customers are using complex storage stacks such as LVM over dm-crypt over MD RAID over multipath over iSCSI and FC with LOTs of LUNs, and we're facing problems in that area which are usually very hard to reproduce. It's also hard to guard against regressions.

Motivation / Problem

Lately the necessary patches to get rudimentary support for the Mediatek chromebook with a mainline kernel got posted. There are some hacks and I'll work on some good solution to get graphics go, at least.

Within SUSE we are using various systems for different tasks. E.g. GitHub and GitLab as DVCS, Jenkins for building or testing, OBS for building… and the list continues. Some of those systems can be interconnected in some way. But not every system can do that, especially if you are behind a corporate firewall and some (I'm looking at you GitHub) have a quota. So wouldn't it be nice to have something like a Big SUSE event bus, where every event we'd be interested in could be queried or subscribed to?

djmount is a neat idea - see UPnP/AV resources in your directly in the file system. Unfortunately the code hasn't been maintained for ~10y, and - at least for me - seems to by plagued by various bugs causing crashes and what not. There's currently no official openSUSE package. This project aims to pick up the code, fix bugs, and make the tool actually useful again. The code itself seems to be in quite a good shape, so this should be doable.

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.

meson[0], a replacement to autotools, is very popular nowadays. It's a lot faster than autotools as far as what I hear and see. Besides lots of GNOME projects has been ported to meson. As one of the maintainers of GNOME Logs[1], I need learn meson and try to port Logs to meson for faster building.

Most large workloads such as SAP HANA require special, highly optimized configuration to run in a virtual machine. Virtual resources such as memory and CPU must be carefully configured to ensure optimum performance of the virtual machine workload. Default VM configuration created by tools such as virt-install are not optimized and often result in poor performance of large workloads due to memory access latencies and incorrect/incomplete information available to the VM's task scheduler.

I want to experiment with three things:

Are you interested in pairing? Are you wondering whether it is something that would help you and your team members in your current project? Would you like to try it out before you fully commit to such an extreme idea? Then this is your lucky day Sir/Madam!

Doc as Code with Asciidoctor, Jekyll, and TravisCI

There is a couple of libraries available for asynchronous and non-blocking processing of HTTP requests (in Java) that can be used to avoid having threads waiting for responses in request intensive applications, for example:

Use this hackweek to practice and learn more about Go.

Mottainai - Task/Job/Build Server for everyone!

Yes this project is yet another project for creating a Suse Manager clone.

The idea is getting a general knowledge of how QT Linguist works, and help FET with some translations.

Time for technical housekeeping in the shared Gran Canaria office.

First part is to support automated builds on git pushes also with gitlab, similar to what we do already with github.com. This means OBS would get notificated in a save way to refetch sources and start build on each commit.

There are plenty of old games that were compiled for Linux - particularly in Loki times around 2000.

Let's dust off our Amigas, hook up our mice and joysticks, and see what elegant software and hardware could do back in the 80s and 90s!

An initial prototype from the last hackweek can be found on YouTube

SUSE Manager can do some virtual machines management, but needs a lot to be complete. This project is about investigating more on that topic.

Elixir is a Ruby-ish dialect of Erlang with meta-programming capabilities, this is my first project using it: pedro . The idea is to create a task manager that would organize tasks (jobs) and manage them in projects. It will be running locally, remotely or both in multi-node setup, will provide CLI, have web UI relying on http and websockets.

Live audio tools could use some work in openSUSE and are fun to play with.

Automate the process described here:

Oficina, a mechanical workshop application developed in Qt/C++

The aim of this project is to finish up the work already done in previous editions of Hackweek in regards to zypper-docker. That being:

Everything is (in) a module now. They depend on each other and you need a whiteboard and a few different colors to understand and remember how.

terraform-provider-libvirt supports CoreOS ignition file/content, which end rendered as kernel command line options (the provider does some nice stuff like allowing you to pass the json content and it will take care of putting it into a temporary file).

I am currently using odpdown for presentations (tl;dr: it lets you write your slides in Markdown and generates Libreoffice slides from that and a Libreoffice slide master (such as a corporate identity template)). It is currently not available in OpenSUSE so it needs to be packaged and submitted to Factory.

A lot of custom-built or ethusiast-level keyboards such as the Planck, Zeal60, Let's Split and many more use an open-source firmware called QMK. This firmware allows you to freely define your keyboard layout and add a lot of functionality (i.e. emitting a different keycode on long and short keypress, dual-function keys, leader keys (think of vi's :)). We could use the Hack Week to add functionality, check the source code for security issues and add support for more keyboards.

Right now portusctl is a tool which is embedded into the Portus source code. This was done out of simplicity and with the hope that we would share as much code as possible with Portus itself. However:

Kernel dumps, provided by our customers, are uploaded by Customer Support to ziu.suse.de and shared via NFS to L3 servers at which they're analyzed. This procedure works, but likely has room for improvement.

OpenFaaS - Functions as a Service

Hackweek 18 Update

Laitos is an open source project written in go, it emphasizes simplicity of maintenance and delivers a complete suite of web, DNS, and mail servers to host a personal web server. Beyond the suite of servers, laitos software hooks into numerous API platforms, that altogether enable user access to Internet features (such as Facebook, Twitter, emails) via alternative communication infrastructures such as telephone (PSTN), SMS, and satellite terminals.

Since there is no real documentation about openQA's lib/ functions I wanted to kill two birds with one stone and write a parser in perl that extracts all function names (and maybe preceding comments) in said directory and improve my perl knowledge by doing this.

Fresh air and motion helps your brain to come up with new and creative ideas.

The SLE15 development model follows the Factory First policy, where all submissions need to go first to openSUSE:Factory and then to SLE15 repos. This way more bugs are fixed, less patches get lost, less backporting is happening etc.

While normally data is passed to linuxrc (including an AutoYaST profile), modern auto-install tools like Ignition from CoreOS support a very interesting method: the QEMU Firmware Config device.

• learn how to write Dracut modules

DAPS, the "DocBook Authoring and Publishing Suite" provides a tool set for easy creation and publication of DocBook sources on Linux. DAPS lets you create HTML (incl. webhelp), PDF, EPUB, man pages, and other formats with a single command. DAPS is used and developed by the SUSE documentation team and hosted on https://opensuse.github.io/daps/ .

• Setup Tensorflow on OpenSUSE 42.3
• Look for a way to package it

Build a base image and template (both kiwi and Dockerfile) for openSUSE Leap 42.3 using the native OBS container building feature.

media.ccc.de currently hosts about 5TB of presentation recordings. The main mirrors send about 5TB of videos each in a single month. Several OpenSource conferences are hosted on media, like the last two openSUSE conference, or the "All Systems Go!" conference. What started as a web frontend for ftp.ccc.de in 2007 has become a complex project that integrates deeply into the tooling used by the VOC team.

I have several themes in progress, they all need lots of work before they could be used with openSUSE. * The gtk people keep changing things so the gtk theme I use to match my enlightenment theme also needs fixing.

BPF Compiler Collection (BCC)

This was planned for previous hackweek (hw16-1)

We need to package avocado, get it into distro and migrate some of our testsuites from ctcs2. Atm avocado is present in openSUSE:Factory and Backports exist at my home project

What is HRV ?

Take some online classes for penetration testing tools and then practice using them. The goal is to learn enough to provide some value for pen testing of real products. Originally I was hoping to have a real cloud to pen test, but that appears unlikely so I plan to set up an Apache web server instead as the system under test. It won't matter much as the goal is to learn to use the tools.

OMEMO is the next generation of end-to-end encryption method for IM applications, which supersedes OTR. Compare to OTR, OMEMO provides many useful new features.

A pocket operating system,can be burned in a usb stick. Not the live usb,you can save all your changes in this.

As in near future, there will be python2python3 in Factory but no /usr/bin/python and in SLE-15 base no python2 it is necessary to start checking/switching dependencies.

L10N for the book entitled Designing with LibreOffice by Bruce Byfield

Quite a big part of openQA is testing the installation of SUSE products. All of them are installed by YaST. So a big quantity of problems found during openQA testruns are YaST problems.

While DDR4 memory has become quite popular, decode-dimms doesn't know about it and is not able to display any useful information for DDR4 memory modules. I would like decode-dimms to provide the same detailed information about DDR4 memory modules as it does for all older memory types.

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.

Deploy an openQA on my locally virtual machine and create 3 openQA test case for nautilus.

While it is important for package maintainers to track the upstream code base activities and backport significant patches in a timely manner, it could be a tedious work when there's hundreds of packages in a project (ahem, GNOME) to follow manually.

CaaSP is designed to be used with containers based on SUSE micro OS, using Salt as the management tool. CaaSP2 GMC is available at the moment. I want to spend the hackweek 0x10 to play with it, figure out how CasSP integrate and work with Salt.

How to deploy container - Docker based on SUSE CaaS Platform.

Problem statement

When doing the backport, I sometimes spend some time to check if the commit comes from a patch series and list all commits of a patch series. So I'd like to create a tool for doing this quickly.

YaST dumps quite information to its own log file (placed at /var/log/YaST2/y2log). That info is very useful to understand and discover what is happening when an issue appears. All YaST modules write into this log file, and the brand new yast2-storage-ng is not an exception. Some improvements are necessary regarding to the logging of this new module:

We got a couple of GSoC projects around Jangouts this year:

SLE Engineering have a large flatscreen in the shared space just outside of Thorsten Kukuk and Stefan Behlert's office

The DriConf-Project inside of MESA has seen its latest update in 2006 and is implemented with GTK+ 2. https://dri.freedesktop.org/wiki/DriConf/

Problem statement

Once a kernel is built, a developer/janitor may want to boot the kernel for various reasons, such as performing simple boot test or running tests and workloads from user space or simply playing around in a shell. However, an easy to use and a descriptive tool to perform those tasks doesn't exist to our knowledge.

Look at this beauty: https://github.com/crowbar/crowbar-core/blob/master/crowbarframework/app/models/serviceobject.rb#L941

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:

A nice project for enhancing the winter time:

kCFI is a tool that enables the compilation of commodity Operating Systems with Control-Flow Integrity protection. kCFI first prototype was developed/implemented during a PhD program held in the University of Campinas, in Brazil. Although fully functional, the tool remains in a very experimental shape, needing to be refactored prior to being released.

port notmuch/muchsync to android, with some java ui on top

I currently use maildirproc for filtering Maildirs downloaded by offlineimap and like its highly flexible approach to filtering a lot (filters Python code). This works very well, except for one problem: after filtering, the next offlineimap run deletes the messages that where previously in Inbox on the mail server and uploads them to the folders they were sorted into. Depending on how many emails one gets, this is a colossal waste of bandwidth.

Try to get back an automatic email notification about new or changed SAP Notes. Since SAP has closed down some of their internal servers, which hosted an unofficial database/API to the SAP Notes, the nice email notification service of the SAP LinuxLab is terminated.

Various improvements to Rocket.Chat, like - adding a IRC/Rocket.Chat gateway

I switch fairly often from working on my laptop alone to working on my laptop attached to the dock with several monitors, and I have to move my windows around every time I switch. I want a tool to save and load window/desktop location configurations. I've tried a few tools and scripts that either haven't worked or haven't worked to my liking. I propose to create a tool that will work for openSUSE.

I'm going to port coreboot to the Dell Latitude E6230 laptop and make it work.

Current virtualization requirements mainly come from fate, and I haven't got chance to try freely many features of qemu/libvirt. So I will try to play it.

Volumio is a great, Linux based, open source music player for Raspberry PI and x86.

Compared with traditional file systems (e.g. EXT4, XFS), log-structured file systems treat its storage as a circular log and write sequentially to the head of the log. I want to learn about this kind of file system via this hack week, to understand how it manages its data and metadata, to understand how it recover back from crash, to understand its advantages and disadvantages.

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.

As live migration is widely used in many scenarios nowadays, spend one week time to study it and try to improve its efficiency, e.g. seamlessly migrate with less downgrading the guest. Another challenging part is memory migration, as it involves the dirty memory's detection, record and copy.

During testing virtualization , I usually met some issue and can not position the issue location (host or guest), so I would like to deeply learn QEMU code, card the work flow, understand communication mechanism between host and guest.

Learning design model can help to produce high quality codes, which will benefit our products.

Learn Vim by reading book of Practical Vim

I'm planning to do some research about RV32E which has only 16 GPRs, but riscv-pk doesn't have RV32E support so that the RV32E aware GCC (https://github.com/kito-cheng/riscv-gcc/tree/riscv-next) cannot build riscv-pk. I'm going to study how the proxy kernel works so that I can do some modification to let it support RV32E.

since i am learning golang, i will make some contributions for the upstream project we used already @suse

Aim of this project is to create scenarios for manual deployment using limited feature set of mkcloud. Useful for situations when full mkcloud deployment is broken. It would help qam-cloud team a big time. We can reuse the result later in automation.

I planned to write a GUI for mokutil since I started the project. I guess now it's time to do that.

The theory behind the partitioning proposal of yast2-storage-ng is that all possible distributions of partitions in the disk are evaluated and the best one, according to this criteria, is chosen. But I have found several examples in which is hard believe that the result is actually the optimal distribution of partitions.

I will implement the ReaR upstream issue https://github.com/rear/rear/issues/1399

During regular L3 work I often don't find enough time to work on the command line disk partitioner parted which I maintain.

While there are plenty of benchmarks that compare different IO multiplexing techniques such as epoll vs poll/select, there's really nothing out there that particularly measures epoll system call latencies under different scenarios. Design and implement a series of performance benchmarks for this call under the 'perf bench' framework.

PVH domains are a new guest type supported by Xen being as lightweight as possible (e.g. no emulation of legacy devices via qemu) while taking advantage of the hardware virtualization features of the x86 processor.

Back in the day, I enjoyed coding on 8 bit machines, mostly MSX. There is now a Kickstarted project to create a successor machine with some new features: hardware sprites, hardware scrolling, better sound, integrated SD/MMC IO and an ESP8266 for networking.

What if Salt Minions no longer need to specify the IP or DNS address for the Master? Or even better: Master(s) can call minions. Of course, for the beginning, we would assume the network is trusted. But we should be able to add further security checks (keypairs etc).
