From time to time we face collisions when two teams would like to play at the same time. As our kicker table moved back to our building, it should be possible to reach the space with WiFi. There is also power plug available so installing IP web camera should be easy enough.

Two trainees embarking on their coding adventure! A lack of beginner-level projects brought us to the idea of starting our own little game forge.

Dive into VLC and fix mixing video and audio sources together with multiple transcoding and multiple outputs.

Over lunch the machinery team was talking about telepresence and mobile solutions and I came up with the idea of abusing a cheap wifi controlled toy tank as base for such a project. So here I am, having a cheap remote toy spy tank sitting on my desktop - waiting to be hacked :)

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

Learn QT and make something to try it.

Recent packages for Chef on the SUSE platforms are in a poor shape. In the meantime, Chef 12 is in the beta phase. Let's use the hack week to polish and update our Chef packages.

bundler-audit is an open source that scans you Gemfile.lock (if you program with ruby) for known vulnerabilities. Let's take the list of issues and enhancements and fix as much as possible

Introduction

<p>WLAN, bluetooth, DVB, DAB, ... I'm not getting any data!</p> <ul>

Born as a hackweek #8 project OtoBUR (https://github.com/ismail/otobur) is an Android app to show Bursa (a Turkish city) Municipal Bus Timeline. Since I own a Windows Phone now I'd like to port it to Mono and later on Windows Phone (XAML).

Using NFC(Near field communication) tag / phone Lock and Unlock ( replace password login ) on openSUSE with Gnome.

> [arbs] is a tool for keeping an OBS project in sync with an ArchLinux package repository. More specifically, I use it to sync [home:roman-neuhauser:arch-community][h:rn:ac] with [community.git][c.git], a mirror of the actual svn repository underlying community. arbs already exists but has many rough edges. the goal of this hackweek project is to make it resilient in the various failure scenarios so it can be used in a truly unattended fashion.

CalDAV [1] and CardDAV [2] are client/server protocols designed to allow users to access and share calendar and contact data on a server. There are many CalDAV and CardDAV clients around, e.a. Thunderbird/Lightning and also free CalDAV and CardDAV servers like Baïkal. With that project I want to create a client in PHP to be able to create and modify data in calendars and addressbooks from websites.

SELinux Common Intermediate Language is a language that allows the creation of SELinux policies. Some of the traditional constrains (tight coupling, nested optionals, ...) are lifted or not as problematic. http://github.com/SELinuxProject/cil/wiki/

This is about starting to use functional programming paradigms that get used more and more? It is mainly about rewriting a small test program (repclean) in a functional style, using immutablity, parallelism and async techniques.

Linux From Scratch (LFS) is a project that provides you with step-by-step instructions for building your own customized Linux system entirely from source. Build the customized linux step-by-step is good way to understand linux system deeply. (Include cross compile TEC which I have interest )

Spacewalk is the upstream project of SUSE Manager. Currently Spacewalk runs on RHEL, CentOS and Fedora, while SUSE Manager runs on SLES.

VOVO is a server-client architecture to determine current abuild load on devel-network machines. The goal is to trigger machines on and off depending on build power. It is an attempt to reduce power consumption. Current status:

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:

CoreOS is a new Linux distribution that has been rearchitected to provide features needed to run modern infrastructure stacks. CoreOS is popular on most cloud providers (EC2, Rackspace, GCE), virtualization platforms (Vagrant, VMware, OpenStack, QEMU/KVM) and bare metal servers (PXE, iPXE, ISO, Installer). Play with CoreOS during hackweek and see how and why it works well for HA.

Storing the devices in libstorage as a graph looks like a natural approach. The boost graph library (BGL) could be used here instead of the selfmade iterator over iterator (not a graph) concept currently used. Together with a redesign of the current objects several features would be simple, e.g. using disks for filesystems, renaming LVM volume groups and logical volumes, switching to and from partitioned MD RAID.

It is well-known that two git commits within a single repo can be independent from each other, by changing separate files to each other, or changing separate parts of the same file(s). Conversely when a commit changes a line, it is "dependent" on not only the commit which last changed that line, but also any commits which were responsible for providing the surrounding lines of context, because without those previous versions of the line and its context, the commit's diff would not cleanly apply. As with most dependency relationships, these form a directed acyclic graph. Sometimes it is useful to understand the nature of parts of this graph; for example when porting a commit "A" between git branches via git cherry-pick, it can be useful to programmatically determine in advance the minimum number of other dependent commits which would also need to be cherry-picked to provide the context for commit "A" to cleanly apply.

Using traditional hardware development tools, apply a Non-uniform Choppy Transformation to a block of ligneous substance. The end result should be a 3D rendering of the Geeko glyph.

GNU Guile-2.2 will be based on brand new backend, CPS(continuation passing style) as the most significant IR, and a RegisterVM. These are the prerequisite for the final AOT compiler. The old Guile-Lua is old for compatible with the brand new RegisterVM, moreover, it uses LL(1) which is painful for hacking. I've rewritten the parser with LALR and all the intermediate part before transfer it to Tree-IL which is another iR before CPS. Besides, I'm trying to add type-inferencing and partial-evaluation for Lua specific optimizing. Although there's partial-evaluator in Guile backend, it's a generic one for all the front-end languages.

Currently whenever there is a test, we need to find or build environment on our own machine or borrow some one else's machine temparorily. I hope we can collect all testing machines in our local team and build a sharable testing environment. Every one can reserve and use the machine, add machine, check machine info to find proper one (hardware and software) for test, share vm images, share other testing related resources, etc.

Learn ceph architecture and try to deploy a ceph cluster.

The virtualization team's automated testing has a long history. It was born in the old Novell Integration Test framework. The virtualization lab ran an instance of this framework for many years. Over time, those who knew the framework left the company, taking their knowledge and leaving little documentation behind. As our testing needs increased, we found the old framework insufficient, but saw little value in improving it given the available open source CI frameworks. Before burying ourselves in SLE12 development, we took some time to move our automated tests under control of a Jenkins instance running in our lab. Tests were configured to run when new packages landed in our SLE12 devel project, ensuring our queued SLE12 submissions were continuously tested. But more is needed.

I just learned about xenctx, which is used to help debug Xen issues. I am wondering if it would be easily ported to KVM. If not, perhaps at least creating the equivalent for KVM may be useful for handling problems with KVM guests.

Each of the core dump upload servers in Europe and USA could be improved if the shell scripts were combined so that the same tasks can be performed on each site, e.g. downloading of all packages needed for crash usage with a specified core dump by allowing for configurable (or even automated) selection of locations to obtain data packages from.

Working on a way to add exceptions using javascript (jquery), php, json, and mysql to modify the generated calendar used to manage who is on after hours.

XFCE currently has no support for monitor hotplugging, which makes it hard to use on Laptops with docking stations. This project wants to add support to XFCE to automatically adjust its display setup when the monitor configuration changes.

Usecase.

• My phone / media player has less storage space than my music collection is large. I charge my phone / media player via USB attached to my computer. I want it to transfer media to my phone / media player in a non interactive way.

Yast team has a great experience in automating tasks that can be done by machines in order to save time that can be used better. We usually use Jenkins for running these jobs.

Why to use automation?

newburn is a system press testing tool. But it is out of maintained. And it is heavily integrated in ctcs2. So replace it with a new one.

Idea is to prepare some advanced template examples for Heat orchestration in OpenStack, which will show: - how HA for VM guests can be used

qemacs is a nice emacs style editor by Fabrice Bellard (qemu's original author). qemacs is small enough so that it can be compiled as a 100kb executable, but also has a simple codebase

terminal has it, git tool has it, so yast-devtools should also provide it for new rake tasks

Currently GCC relies only on the most generic alias analysis when attempting to track data in aggregates in interprocedural (IPA) optimizations. In the course of this project I plan to revive patches for using simple escape analysis to track all data which do not have their address escaped and use that information to track constants within them, analyze the impact on a number of benchmarks and submit them to GCC trunk.

During the YCP Killer project, Y2R didn't translate most YCP operators and builtins into equivalent Ruby constructs but into library calls. This was necessary to preserve behavior in various edge-case situations, mostly when nil was passed around. The resulting code is often long and hard to work with. Example from SlideShow.rb:

Investigate the state of bioinfo FOSS (mostly interested in DNA sequencing and sequence analysis) on Linux (and possibly other platforms), learn some algorithms, learn to use the available software, find what needs to be improved and if time permits, start improving.

If nothing is changed, no Hackweek T-Shirt awaits us. So, taking the initiative, I am searching for other creative minds to collaborate with.

It's 1.5yrs since we've launched the last Studio version. Customers are asking about a roadmap, a new version... After discussions with AJ, Adrian, Alex, I want to create a draft plan/concept how such a Studio successor could look like.

Some people prefer LaTeX for creating documents and presentations. The templates provided by Marketing don't include one for Beamer

Project Description

The idea is to have an internal web page that mainly presents new SUSE employees or the ones you might not know yet. Other topics can be covered like reports about hack week projects or other interesting stuff apart from the daily work we all do. As a start there would be a questionnaire which results are posted on a web page.

The idea is simple. Dice is a light weight build service for KIWI images with full control over the build power by the user. At SUSE we have the buildservice which is the full professional version of a build service for packages, images and also products. As a normal user I can provide input and I get some output but I have no control what happens with my data, when it's being processed and where it's being processed. That's by design and works great, thus not meant negatively. I'm a 100% fan of the buildservice

Is Redmine good enough for manging projects?

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

Moses is a statistical machine translation system that allows you to automatically train translation models for any language pair. Intention of the project is to tune up existing software, where a glimpse shows that majority of time is consumed by memory allocation, dynamic casting and other calculation non-related stuff. I would like to inspect many techniques (like perf profiling, GCC LTO, GCC profile-guided optimization, code refactoring, OpenTuner, etc.) which may bring really significant performance gain. Moreover, it would be really beneficial to come up with a cookbook that can be used by folk in general. If possible, I would like to create a step-by-step performance improvement graphs.

Having gotten access to some SMR prototypes it should be possible to tweak btrfs to run natively on those devices. Using SSD mode helps a lot, but there is still some work to be done. So this will be a good chance to learn something about the inner details of btrfs and see if I can get it to run on SMR drives.

Gerrit is used for code reviews by openstack and its related projects (e.g. chef cookbooks). The web interface is too slow when you get 100 changes to review each day. It would be nice to have a faster CLI. There are already some python client libraries available. I am thinking about either doing this as a standalone application with python and something like ncurses or an emacs/lighttable plugin. https://github.com/mapleoin/gerrit-el

• improve incident-view

openSUSE 13.2 is taking shape on ARM, but we need to make sure we smoothen its edges to make an actual release out of it. The goal of this project is to make sure all devices we should run on actually work and that the last few packages necessary for productive use of ARM devices work properly on 13.2.

OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. The goal is to get familiar with OpenCV API and with the available algorithms. Specifically, I want to look into these particular tasks:

I have a Canon PowerShot S120, which allows for browsing / copying photos over WiFi. There are apps for Android, iOS, and Windows to do that. The protocol uses upnp to discover the camera and the smartphone/computer and them some HTTP-based protocol. I have some code using libupnp for the discovery and a perl script that is capable of transfering one file, but it's far from complete. Plus, I need to refresh my memory, because the last commit is from January :-(. Now, there seems to be some support for such cameras in gphoto already. So the plan is to dive into gphoto and use what I learned about the protocol to fix the gphoto support. If you own some other WiFi-enabled Canon camera supported by the CameraWindow software, let me know.

Plan

RandR is X11 extension for configuring monitors and since version 1.4 also secondary GPUs. These secondary GPUs can either provide additional monitors to output to or can render individual applications instead of the main GPU. (Or even both at once.) Once a secondary GPU is configured to do render offloading, applications can be started with DRI_PRIME=<id> environment variable to actually render on it instead of the main one. There are also USB GPUs (dummy framebuffers) that can be hot-plugged.

My idea was created out of a need in my current team(Hardware-enablement). Whilst excessive SLE testing on multiple machines i was forced to remember tons of ips to debug remotely. Since i had to reinstall new releases over and over again, ips differ, obviously. My approach to make life easier would be to create a simple cli to manage and administrate multiple connections on my local machine.

I`d like to create new set of tools for mirroring ISOs and repositories from "master" server to slaves/mirrors. ATM we are using very old and buggy set of internal tools. scripts are written in several different languages (bash, perl, python) and on always easy to undigested their purpose.

Implement improved ftrace infrastructure for PPC64LE (goal 1), s390x (goal 2), ARM64 (goal 3) that is able to support kGraft and doesn't have a performance impact. PPC64LE has an experimental (untested) patch by Dinar Valeev already, s390x works, but has a 10% performance impact on the system, ARM64 is entirely untouched.

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 :-)

Those working remotely or managing a distributed team know it: face time is invaluable. The former openSUSE team has been using http://sqwiggle.com to keep in touch and Google hangout to hold a stand up meeting every morning. We like the Sqwiggle approach. Although the last updates have made it worse, the concept of having a peep to your colleagues' desks to know if they are there (even if they are working hard or just talking to someone) and the possibility of starting a video conversation just clicking on the face shot can do a lot in reducing distances (and in killing the temptation of working naked for home-officers).

Non-Android Linux can already be booted on several devices that are based on CPUs from Allwinner, such as the A10 and A13, but support for the newer A23 is still incomplete. I want to use this Hackweek to work with the folks of the sunxi and Lima projects (http://linux-sunxi.org/, http://limadriver.org/) to get Linux up and running on an A23 based tablet.

The new SUSE Floor is nearly done. The core functionality is already implemented and only some basic features are left.<br> <br>

I intend to work on translation of KDE to Czech language. http://i18n.kde.org/stats/gui/stable-kde4/team/cs/

SeaMonkey is the successor of the Mozilla Suite. The mail client allows connections over POPv3 and IMAPv4. In some cases one wants to leave the program running for longer periods of time, but once the mail client has password for a mail server it just stays connected. In case of "keep everything on server" profiles this means that the mail may stay accessible even when the machine is left unattended (which it often is). The purpose of the extension is to enable requesting the client to forget mail server passwords, so that the mail is no longer accessible without entering it again. http://www.seamonkey-project.org/

Pebble smartwatch is a nice gadget I own and I'd like to start playing with it at the code level. One goal would be to create a SUSECon / conference application for it, allowing to choose which talks I will attend and make sure the watch will notify me in advance a session will begin.

Create a set of ready to use Dockerfiles based on OpenSUSE, and find a nice home for them to live in. Useful containers or just for fun, let's dockerize-it all.

Write a simple command line tool for getting the open pull request from github and put it into a trello card. The tool should periodically update a list of pull request. In addition it would be great to have a connection between the trello card and github pull request.

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 teh SUSE documentation team. The official DAPS release is 1.1.7. SUSE internally DAPS 2.0 rc2 has been released. A few issues need to be fixed (mainly closing open bugs and adding missing test cases). The goal of this project is to fix these issues, so DAPS 2.0 can be publicly released.

In order to build a community around crowbar, our cloud installer, we need to get this running on openSUSE as well. So let's find some time to move the packaging of crowbar from the ibs to the obs! In the end, there should be working packages in

The Problem: many bugs filed for openSUSE go to the screening-team by default and often remain there for weeks, so that developers (who would be interested in analyzing or fixing these bugs) do not learn about them. However, the screening process is a hard one

In short, give second breath to http://hall.suse.de/bugs/defects.cgi. Long version: Create a generated page reflecting SUSE organizational structure and containing links to useful generated Bugzilla queries and charts like:

zypper is magic

A number of experiments suggest that it may be feasible to run zypper from an openSUSE 'live' media against a 'foreign' RPM based OS installation (eg. CentOS) and then 'zypper dup' to openSUSE

Intro

The SUSE Manager client stack is rather simple, in regular intervals it asks the SUSE Manager Server for scheduled actions and executes them.

Installing linux on z/VM requires some way to punch kernel/initrd/parmfile into the reader which in turn can be booted. In a previous hackweek, I wrote a small tool, that makes it possible to do so directly from the internal ftp server. this has been proven valuable but not perfect. This tool should be improved to

Talking to people, getting the information about what had happened in the SUSE history, bringing all together to kind of a chronicle. Let's give it a try :-)
