Once again, the SUSE band is coming together to make music and we're planning a party this time round!!! We have a band name :-)

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.

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

Gang(ghe@suse.com) and Eric(zren@suse.com) will do a functional comparison analysis between OCFS2 and GFS2 during this hack week. we will try to setup a GFS2 cluster environment, compare the features and performance with OCFS2,

As every hackweek, lets package/update/cleanup some stuff fore factory: Update/package:

We are right now testing a patch to Janus that will hopefully give us the stability we were missing in http://jangouts.suse.de. As a consequence, it's reasonable to expect a wider usage of Jangouts inside the company. Thus, I want to share maintainership of Jangouts as much as possible. The more developers know how to fix errors and implement features, the better. We already have a roadmap for the next two versions (0.4.0 and 0.5.0) but I don't want to spend my whole hackweek implementing those features in isolation. I would rather follow a workshop approach to welcome new contributors within the company (or outside, of course), so we get the stuff done and fix the single point of failure for the same price.

"Let’s Encrypt is a new Certificate Authority: It’s free, automated, and open."[1]

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

Working remotely has many advantages, but you sometimes lack some infrastructure. Specially if you use several computers or you share space with other SUSE co-workers. We are 3 Susers in Gran Canaria and we plan to share an office. So we have bought a Cubietruck, a tiny device with minimum power consumption, an ARM processor, a SATA interface and a Gigabit ethernet. The plan is to come-up with a set of recipes to configure such device to:

Description

It can boot up from udisk/floppy.

Minimal objective

This is what we consider is the minimum result we can achieve at the end of the hackweek.

Given that Leap is now available, as installation media, we are going to dedicate some time to release ready to use 'Just enough Operating

In https://github.com/SUSE-Cloud/automation/ we already have mkcloud, which can setup a whole SUSE Cloud on a single host for testing. However, it would be cool, if (instead of a single machine) we could use cloud.suse.de with its capability to add extra networks as requested. This can be pretty easy, as much of the mkcloud code is about making libvirt do the right thing

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.

We are using various tools, many of them are not yet in Tumbleweed (such as rst2html5, git-pimp and so on), aim of this project is to get them there.

I'm interesting in SLEnkins project and I want to learn it a bit. I will try it and know how it works and how to use it.

It's just my learning project about Docker, I will research and learn how to deploy and configure Docker and Docker cluster, and also I will try to learn everything related about Docker.

Packman reduction

In openSUSE Asia summit 2015, there was a talk about the software defined networking, from the virtual switch, the controller, to the simulator. Just want to take a look at open vswitch and Ryu to learn more about SDN.

gdb-kdump (and libkdumpfile) needs a plenty of improvements and tasks to be done. For HackWeek 13, Vlastimil chose to work on SLAB memory support, Petr, amongst other things, reorganized the libkdumpfile code and alnovak begun with libkdumpfile's ppc64 support. Our status in 4/5 of HackWeek 13:

SLAB

DAPS is the tool used by the SUSE documentation team to generate HTML, ePUB, PDF, ... output of the SUSE manuals from DocBook XML sources. It uses the suse-xsl-stylesheets for this purpose. Currently three different suse-xsl-stylesheet brands exist: SUSE, DAPS, openSUSE. Branding is done by adjusting the xsl-stylesheets directly. It would be desirable to be able to easily change the branding, e.g. via a simple config file in the style of /etc/sysconfig files, since most people cannot hack XSLT. This is also the number one enhancement request we get from DAPS users outside of SUSE.

Read in a crash or oops-style backtrace and access DWARF information to output the current content of the stack and registers in term of symbols, and the the crash commands to dump/pretty print them. In other words, when looking at a crash dump, answer the questions "Which variable is currently stored in $rax? What is the structure of the stack? Which variable is stored at $rsp+16?"

Status at the end of hackweek 10

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: - RESTful backend App::Dochazka::REST (with lots of help from Web::MREST)

While in the past MIPS boards were either low-end PIC32 or found in routers running OpenWRT at most, Imagination themselves have recently released the Creator CI20 board (Ingenic, MIPS32) running Debian. And the Shield Pro (previously iGuardian) kickstarter project (Octeon-III, MIPS64) promises to become a playground for testing KVM hardware virtualization. Porting openSUSE to MIPS will involve setting up an OBS instance linked to Factory (update: done) and cross-compiling a set of packages for an initial bootstrap (update: in progress). Maybe this can be scripted to some degree, as there will be some overlap with the ARM ILP32 port project.

At SUSE LabsConf 2015 we decided to run some sort of automated tests on the SLE and openSUSE kernels after each push to kerncvs.suse.de In order to make this work the kernel has to be build, a initrd and a rootfs image has to be generated for use with qemu, it has to be booted and tests have to be run.

My car has it, nowadays every smartphone has it. But what's actually the math behind GPS (GLONASS) technique?

This is about porting the old KDE 3 based KDirstat to the latest Qt 5. KDirStat didn't use that much KDE infrastructure to begin with, and KDE seems to be more and more a moving target. Project repo and web site with more details:

To say it's a review, it's better to say it's a good way to learn from others. I'll review test scripts in openQA project as much as I can, digest them and learn how to write Perl script more pretty. I'll make some notes for sharing.

Use python "textgrocery" class to classify the webpage informaton . It's very interest to analyze the "focus" of a webpage .

Smalltalk is an object-oriented, dynamically typed, reflective programming language and Pharo is a modern, open-source,

libvirt+Xen should support the qdisk (qemu) rbd backend, providing native access to block devices hosted on Ceph clusters. Adding this support to the libvirt+Xen toolstack will also improve interoperability with SUSE Enterprise Storage.

and find out how it compares to salt

This hackweek, we will be hacking on Weblate and adding features that we need to use it as a translation tool for openSUSE! Chief among those is a better permission management that would allow us to assign different rights to different projects, languages, distributions etc.

SCC doesn't require an email address, so could you automatically generate random keys until one matches and effectively 'steal' SCC licenses from customers?

Writing code is wonderful, but it gets its real value, when it's released and shipped to the world. You know the mantra: "Release early, release often". Releasing code is not hard, but it involves a lot of details, and you want to get them right, because a release is this public statement "Hey, it's done, it works, you can use it." and you can't take a release back, once it's out there. To help with releases there are tons of release scripts which try to automate things. But they usually are quite fragile in case something goes wrong and a pain to test and maintain.

Our QEMU/KVM testing needs to be improved. I plan on working on an ontology to help form the basis of a thorough test matrix for

While programming is occasionally a very rewarding activity, it's mostly a chore and the rest is filled with frustration. Let's teach an unsuspecting youngster program! To fulfill this nefarious goal I've set out to help my colleague without prior programming experience get hooked on programming, starting with python. The student finished an online tutorial and we pair programmed a tiny-fix-turned-massive-change in a tool used by our team.

The Nvidia Jetson TK1 is an SBC with Nvidia Tegra K1 SoC (quad-core Cortex-A15, 32-bit ARMv7). I have openSUSE running on the Jetson TK1, but KVM is currently not usable as the CPUs are not booted in HYP mode. Thierry Reding of Nvidia has some work-in-progress for U-Boot and upstream kernel that I would like to test.

The software is a rails app with an Angular.js frontend using the gphoto2 library to trigger a Nikon D60 camera. Features: take pictures, browse pictures, automatic upload to a gallery (tumblr, flickr, owncloud), qr code for download,

I'm trying to write a static analyzer for Lua programming language. And I've ready done some parts, say, lexer/parser/AST/types...etc. The challenge part at present, is to write comment-based type annotation, for later type-inference. I plan to implement it in a week. I've spent years on this area. Hope I'm lucky in hackweek.

During the last CSM workshop we identified the need to have a good way to share the images we use for testing. We have documented the requirements and the current status in this wiki page (we even have a diagram). So analysis is done... it's time for action. The solution should be relatively easy to implement using our portfolio of solutions. Coordinating all the potential users should be easier during Hackweek, specially since I'll be in Nuremberg (and I can physically chase most people ;-) ).

The idea would be to create a qt5/kde5 based utility that can use local raw images as well as download a list of sources from a remote site. The idea is to provide a user interface that can be used by any user as well as a user interface that can be used in kiosk mode for booths so that a visitor can put a usb pendrive in any usb slot, select the image he/she wants to write to it and get it written in parallel to other usb memories. https://github.com/openSUSE/imagewriter seems to be abandoned, so probably part of the backend will be reused and the user interface will be rewritten from scratch, but anyway this will be reconsidered at the first task in the project.

The goal of openQA is "test as a QA engineer". But openQA has no ears - all we can test for are DTMF sounds. And even those are very bad. So my hackweek project is to do research on how to do proper sound verification. The keys are proper normalization of the volume and the sample rate.

As we know, we have ABC notation or GNU Lilypond for music staff. It takes ASCII as input and generates music scores and even MIDI format, which is very convenient for people to type music in computer.

Hallo Welt!, the company behind Blue Spice Media Wiki (an open source, subscription based enterprise wiki) is interested in howto package their PHP software, get it into OBS and into the whole workflow with openQA and learn how to write automated tests. This is such a generic task that I though documenting it might be worth an afternoon at hackweek together with Richard (openQA) and Darix (OBS and packaging). I'll reserve a meeting room, doc team will provide the documentation of this workflow in a "SUSE best practice guide"

Create a USB device that, when configured and connected, exposes one or more Ceph RBD images for use as USB storage, allowing for: * Ceph storage consumption by almost any system with a USB port

This is about writing a tool to find differences in assembly files generated by gcc. The goal is to find the symbols in a program that have changed by a source code patch. This information can then be used to create and/or verify kGraft patches.

The Atom Editor

There is a pretty nice open source text editor and IDE called Atom,

It is fabulous to get machines from cloud for automation testing, and there are lots of things to learn in cloud. So I will start the cloud journey in this hackweek, to learn suse cloud architecture, various technologies inside cloud, and try to deploy one.

Since I'm a maintainer of Gnome-Logs, I'd like to hack on Gnome-Logs. During the hack week I'll focus on the <a href="https://bugzilla.gnome.org/show_bug.cgi?id=753471">bug 753471</a> of Logs. Generally it's a new feature, allowing Logs to show logs entries dynamically(when new logs appended).

COLO or Coarse Grain Lock Stepping is an High Availability solution that builds on top of Remus, 1. investigate Xen COLO implemention and try to play with it.

Since my Orange Pi board just arrived, I will play with it. This includes:

Tronsmart has a Rockchip rk3368 based set-top-box [1]. I want to use it as a arm64 based workstation running openSUSE.

I intend to learn little bit around apache httpd, get acquainted with some native modules as well as look at apache2-debugging-modules package.

My hobby project is about using Lego mindstorms to turn a lathe / turning machine into a CNC. One missing piece is the "CAM" part that takes a 3D model and produces gcode that determines the tool-path.

I want to use this week to familiar with the SUSE products that i don't have time/chance to participate. For instance, SUSE Cloud, SUSE storage, Docker etc... Just like the presentations in SUSEcon 2015 closing keynote.

During hack week I will carry on the research I started to write my thesis. The work is called "Turbulence Driven Clustering in Nematic Active Particles" and will (hopefully) make it into a Physical Review Letters paper.

Based on the little-used HTML5 outline spec, investigate&implement an in-browser tool (currently a chrome extension or browser user script) to easily, interactively scrap a documentation web page into an 'index-content' map for (offline) searching. Motivated by the fact that most scrappers today are command line tools, too tech-savvy.

For our daily work, usually we need to check running result from openQA as a good reference for the quality of a specific build. I'd like to take this chance to make openQA deployed and try to review the test scripts.

The goal is to jump forward with this fate: https://fate.suse.com/319319

The Idea

Since some time I am interested in getting better at C++ and learn more about Qt framework. Since I learn best with having a project/goal I came up with this:

I want to learn JavaScript or CoffeeScript and how to write Gnome 3 extensions. I think that the right task for learning JS/CS could be work on extension for our wicked network manager because I miss some NetworkManager style plugin. Very basic extension for wicked should contains following:<br>

This hackweek, i will try to clear some bugs reported against DLP libraries as libvisio, libcdr or libfreehand. I did not have time to work on them since the last hackweek and I hope to add some new features and silence the most annoying bug reports.

96 boards are the series open source boards with same size and interface launched by linaro. There are two arm 64bit boards and one sensor kit in my hand.

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. It makes use of erlang OTP, web framework phoenix that is inspired by rails. Author of elixir and main contributor to phoenix is Jose Valim, he's also the author of devise rubygem and former contributor to rails.

I want to learn Erlang and see if it makes sense to use it in the context of High Availability (it would certainly seem like it). As a learning project, I want to try to reimplement my koi project (https://github.com/krig/koi) in Erlang. Koi is a minimal cluster manager I wrote in C++.

I have a few ideas of improvements for the delogo filter included in ffmpeg's libavfilter. As a first step I would like to clean up the code by removing one unneeded option and then removing all the subsequently dead code.

using perl's Inline::Python module, it should be possible to define openQA test modules in python instead of perl.

A normal Xen server today has many single points of failure. Those can be reduced by disaggregating Dom0 into multiple domains (xenstore, driver domains, admin domain). Following this path to it's logical end will lead to a setup where the running domUs won't be depending on Dom0 any more, so Dom0 itself can be made restartable. This project aims at beginning with a prototype by setting up a configuration with a xenstore domain and a driver domain for networking. This will allow running a pv-domU with network resources only (nfs or iscsi root file system) no longer needing Dom0 to run.

As a counter-program to the daily usage of dynamic languages, I want to use this Hackweek to explore the web stack provided by very good static typed languages: - Haskell (e.g. Servant)

Openstack Congress provides Policy as a service solution for Openstack based clouds. Policy based fulfillment makes it convenient to write policies for VM migrations and evacuations based on data monitored from various data sources. The aim of the project is to integrate the service to SUSE openstack cloud and evaluate the use of policies as a means to develop HA solutions. The steps for this project:

By analysing a VNC session, we can create a draft of an openQA testcase (detecting keystroke, mouse click and generating fullscreen needles). The project is to :
