Once again, the SUSE band is coming together to make music and we're planning a party this time round!!!

www.opensuse.org is the single most accessed page in the SUSE/openSUSE universe. With 1.5 million visits per month it generates 2.5 million page views and has around 500 people on the page at any given time. Yet it's one of the oldest, crufty pages we have!

New Development

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.

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.

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.

Make a final attempt to implement a graphical user interface for grub2 (gfxboot2).

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

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

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:

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.

In last hackweek, I implemented a RSA private key parser in kernel: https://github.com/SUSE/hackweek/wiki/RSA-private-key-parser-in-kernel

SUSE currently consumes a lot of electricity for keeping servers up an running as well as workstations at the office rooms, air-conditions and so on.

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!

Use machine learning and natural language processing techniques to analyze the changes made in a project, and classify them 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

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

This is about starting to use functional programming paradigms that get used more and more?

What's about an app that helps you with downloading openSUSE documentation?

Machinery supports inspection of SLES11 and SLES12 systems right now.

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 :-)

In short, give second breath to http://hall.suse.de/bugs/defects.cgi.

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.

OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library.

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

Project Description

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.

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.

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

Package a basic, stripped down version of sysvinit for emergency cases, so you can repair a failed system without interference. My goal is not to replace systemd with sysvinit again, but to provide a sysvinit-base package that does not have any dependencies at all and can just be installed on any system. sysvinit will only be used in exception situations by specifying the kernel parameter "init=/sbin/init" or something like that. The package will come with the binary, a minimal inittab and a basic boot script that does only the really needed stuff.

After https://hackweek.suse.com/projects/105 the next thing to merge is hermes.

This will greatly enhance the usefulness of QEMU virtual serial ports, because the Linux kernel interprets a break on the serial console as a SysRq, but there is currently no way to pass this signal over a pseudo-terminal.

I intend to work on translation of KDE to Czech language.

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.

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.

Two trainees embarking on their coding adventure!

We are not hacking on the keyboard but with our own body, learning techniques to relax and strengthen the body to fight gravity. Welcome to a daily training session (3 - 3.30 pm) during Hackweek for an introduction with lightweight exercises.

Learn more about network performance testing tools. I would like to get more fimilar with netperf and iperf. Try to find out what's different between netperf and iperf. And have a look at what's new in iperf3.

Learn the grub2 network stack and have fun with ipv6 network booting. :D

I`d like to create new set of tools for mirroring ISOs and repositories from "master" server to slaves/mirrors.

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.

Plan

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.

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.

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.

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.

Usecase.

Learn ceph architecture and try to deploy a ceph cluster.

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).

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.

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.

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

Introduction

The goal of the project is making the gdb able to open compressed kernel dump - access its memory contents at the very least.

The goal of Project MySelf is to build a system to collect data about yourself in a safe and private way, so that you control your data and you can decide what happens with it.

GNOME is important to openSUSE and other distributions. I would like to help with the translation of GNOME. Mainly, the focus will be on the chinese (zh_CN) translation of GNOME 3.22 and 3.24 user interface.

I want to gain some knowledge about CI and devops. I wrote a script to generated configuration files for pxe server and slp sever.

Investigate the good way to put sikuli into openqa.

A web frontend for the mirrors in the mirrorbrain database to allow the mirror admins to manage their entries themself.

In case any of the source files changed, openSUSE Build Service rebuilds the dependent packages regardless of whether that particular modification affects the dependency. This makes our resources footprint bigger (and the electrical power bills higher). It also affects users, because every new package build causes the package manager to include that package in the next update thus consuming network bandwidth and resources of users' computers.

Look once again on Xperia Tablet Z and try to have there openSUSE running natively as alternative operating system.

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.

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.

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.

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.

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.

How many times have you created quick and dirty script to generate C tables, parameterized code, etc. ?

I'm in SUSE for about a month and as a fresh graduate I had to learn a lot of stuff during this period. And there is a bunch of other things I will have to learn of course. Therefore I would like to use Hackweek to deepen my knowledge of various tools, processes, techniques or other packagers related stuff. However it would be quite a pity to hold the acquired information just to myself. So I would like to keep the result of my learning for further usage either by enhancing the Innerweb wiki, the public openSUSE wiki or by creating new wiki for packagers' purposes.

DAPS (https://build.opensuse.org/package/show/Documentation:Tools/daps) is a tool we use in the documentation team to create/validate/export/... docbook documents. It's currently available for SUSE and openSUSE systems, and I believe that packaging it for Debian GNU Linux would help both the DAPS and the Linux community (and me myself as I'm using Debian at home as well :-)

cscope is a great tool index C/C++ sources and allow to navigate through the code. I have learned that the project is mostly dead and what is worse it uses its own database format to store the index. I would like to see some extended functionality in the tool - e.g. search whether a function A is reachable from B, filtering search results per-file, fix functions with function parameter detection (such functions are not recognized properly currently) and some others.

Predicting the non-functional properties of a Ceph cluster can be quite difficult. There are many inputs in the hardware setup and software configuration that affect the resulting availability, reliability and performance (latency and throughput at nominal levels and during degraded and rebuild times).

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.

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.

The idea is simple. Dice is a light weight build service for KIWI images with full control over the build power by the user.

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.

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.

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.

WLAN, bluetooth, DVB, DAB, ... I'm not getting any data!

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.

To add more flexibility, variability and increase testing capacity we would like to move QAM cloud nodes from physical machines(in NUE) into virtual environment.

Make an interactive wizard that helps to go through configurations of mutt / mbsync / msmtp / notmuch / mailcap / links etc.

I'd like to add a 433MHz receiver transmitter module to my raspberry pi - I know there are some kits, but this will require some hardware poking and soldering and I'm looking forward to it. The goal will be to receive the signal of some remote temperature and humidity sensors, decode the signal - understand their data structure and display and log them accordingly.

While packaging node.js modules, which often depend on specific versions of other node.js modules, sometimes many of them, you easily end up in dependency hell, and maintaining an OBS project with a few hundred of those modules can be a tedious task.

The CRUSH algorithm determines how to store and retrieve data by computing data storage locations. CRUSH empowers Ceph clients to communicate with OSDs directly rather than through a centralized server or broker. With an algorithmically determined method of storing and retrieving data, Ceph avoids a single point of failure, a performance bottleneck, and a physical limit to its scalability. CRUSH requires a map of your cluster, and uses the CRUSH map to pseudo-randomly store and retrieve data in OSDs with a uniform distribution of data across the cluster.

Starting with CUPS 1.6 things have changed considerably. Clients are no longer discovering broadcasted printers anymore. Distributions (e.g. Debian) has backported the original protocol into cups-daemon package but this doesn't seem to work either on my laptop. I would like to look and try to understand what the hack is going on here.

The idea is to produce a standalone, independent tool to save and restore windows positions and sizes, analogous to a similar feature in KDE desktop. This would be handy in various lightweight desktop enviroments.

The kdump package can now use SMP and multiple targets with constant memory requirements. The goal of this project is to find the optimum parameters for dumping a very large machine (SAP can give me access to 6TB, SGI is able to test with 64 TB).

Current kGraft implementation allows to apply new patch only when the previous one is applied to the whole system. Every task is handled separately and it needs to wait for a safe place to switch. It might take a while, especially when the task is sleeping.

I had presented the "Wicked Network Manager" talk at openSUSE Asia summit @Beijing. I would like to keep studying the topic continuously. Getting involve the source code and study the operating style and components. I also met some problem after discussing and testing issues while my research , I want to keep it as a record and writing the technical document on wiki too.

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.

kGraft is SUSE Labs answer to the rising need for being able to patch the running kernel without rebooting the system. I think this kind of tool is very cool, so by this hackweek chance, I want to investigate it how it works and how it was implemented. And also by this chance, I hope I can improve my ability of kernel hacking. If you are also interested in kernel live patching, please join this project together.

Q: How many new bugs opened over time for a package?

OpenCV is an open source computer vision and image processing library (http://www.opencv.org).

More and more customers use our products in mission critical environment. They have a huge need that things run smooth. With Hack Week we have the challenge

The primary motivation for crash-setup (created by l3team) is to make kernel crashdumps deployment and crash using as easy as possible. This has been the case for quite some time except the tool was quite l3slave centric. With a great help from tcech the tool is close to be fully usable from other machines and !.de network as well.

We had a quick course of Coccinelle during the last Labs conference. The tool is really great and I would like to explore possibility of checking lock invariants for particular functions. Julia was really prompt and implemented something that should help but I didn't get to it since the conference.

If you want to use the full potential of SSDs as primary (and possibly only) storage on SLE or openSUSE systems, you are supposed to perform several configuration settings to make it fly, including:

There is quite a popular Android software for connection OBD standard adapters but not for older, brand specific ones. One for pre 2001 VAG cars is this one:

Although I've been maintaining CRIU package, I had little time to play with it recently. It's still interesting especially in combination with various containers. So let's spend (or waste) some time.

provide a summary report of data from a sar data file.

Play with Docker orchestration tools like the ones provided by CoreOS, OpenShift and kubernetes. Provide packages for openSUSE and SLE.

Retty is a tool for changing stdin,stdout,stderr of a running process (http://pasky.or.cz/dev/retty/) which may be handy if you want to attach to a process running e.g. from a died ssh session, changing running process to run from under screen(1) etc.. Currently it doesn't work for 64-bit systems and it doesn't handle changing of a controlling tty of a process (which may be possible using setsid() and opening a new tty). The aim of this project it to fix the above deficiencies and package the tool in OBS.

With many Proof of Concepts (PoCs) going on for SUSE Cloud, the development team has observed that we have no clear path on how Sales Engineers (SEs) and sometimes dedicated support engineers (xSE) can receive technical support to successfully complete the projects, often leading to escalation calls and even firefighting on-site visits by developers. Goal of that project is to come up with a best practice guide and to eventually set expectations on what's possible from a development point of view. Results should be documented in a central internal location and announced to all relevant parties.
