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

New Development

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

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.

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

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

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

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.

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:

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.

One of the winning factors of Docker is the Docker Hub. This the a place where the Docker community shares their images. Thanks to Docker's integrated build system it is possible to create new Docker images by just extending an existing one. That's why the Docker Hub is so useful.

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.

Currently, the usual way to communicate with VM instances in the cloud from outside is ssh. This is okay for most uses, but a) does not work when you mess up with the guest's ability to network and b) requires a free floating IP.

We have some internal systems for videoconferencing like Big Blue Button or OpenMeetings. But in my experience none of them can compare to Google Hangouts, which is still the best free (as in free beer) alternative for videoconferencing with integrated screen sharing.

Introduction:
We are doing virtualization related tasks, How can we still not know how

Create packages for SLES 12 s390x in obs.

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

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

Spacewalk is the upstream project of SUSE Manager.

Port the Fiurefox extension FireTitle to SeaMonkey.

Using an arduino nano, a rf23b (http://www.hoperf.com/rf/fsk_module/RFM23BP.htm) wireless module (or anything like it) and a solar panel to build a mesh network node that can be used to quickly deploy wireless networks.

Occasionally, new versions of openQA break things. How do you stop that? MORE TESTING!

Cover more cornercases for spec-cleaner to allow the swap of formatspecfile due to its bugginess in comparsion.

Get openSUSE running in parallel to Android on a regular and rooted Android Smartphone. On top of this try to get a graphical desktop running using Xvnc available for Android.

netfilter.org states that "nftables is the project that aims to replace the existing {ip,ip6,arp,eb}tables framework." The nftables kernel code was merged into the mainline kernel in January 2014. So it's time to get started with the new Linux firewall framework on openSUSE.

Using dynaname it is already possible to securely auto-update DNS records in a bind9, but this still needs a linux machine. This project is about building a CGI frontend for it that makes it a replacement for the discontinued dyndns.org service.

• learn general information about them

Now we are lack of using internal wiki page to solve problem. One of the reason is that we don't know if it contain the solution we need, and it's not convenient to search it manually in wiki page. It's much more slower than using google. In one group, we are most likely facing the same problem during work. So keeping the best solution, which we got from searching engine, in internal wiki is an efficiency way to collect standard workflow.

A frame work for automatically analysis the result of the performance test. The tool can be used manully as well as used throught openAPI.

A new Puppet Master will be set up for the openSUSE and public SUSE infrastructure. We will need to move the puppet code from the old server to a new Gitlab instance, deploy it to the new box with r10k, and perform syntax, validation and RSpec testing through ci.opensuse.org

Try some things about Docker and Understanding Linux Network Internals

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.

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.

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.

It's a tool or website for Bej employee to manage his(her) leave days, then they don't need ask HR for each time.

The Firefly-RK3288 is the first SBC with the Rockchip RK3288 SoC, the first available chip with Cortex-A17 cores (32-bit ARMv7). I received such a board just in time for Hackweek Interstellar and will be looking into booting an upstream kernel with openSUSE 13.2/Factory rootfs.

The Inforce Computing IFC6540 is an SBC with Qualcomm Snapdragon 805 SoC (32-bit ARMv7).

The Nvidia Jetson TK1 is an SBC with Nvidia Tegra K1 SoC (quad-core Cortex-A15, 32-bit ARMv7).

Work towards release of Weblate 2.3, the roadmap is in the issue tracker:

Implement file system image build using the Builder infrastructure. The project will create additional builders for the ext filesystems laying the ground work for restructuring other filesystem builders.

In order to have complete cloud experience on Power platform it needs some missing pieces to be available: * SLEShammer image (SLE11-> SLE12)

The goal is to use the work from the debug-early GCC branch to generate better debug information for LTO compiled objects, especially with regarding to language specifics like classes and templates. This has now been achieved and openSUSE Factory

openSUSE Connect is almost forgotten tool used only for elections. It would be nice to update it, polish it a little bit, disable functions that nobody uses and fix those few that people would actually like to use.

I'm currently using LastPass as password manager but it has several drawbacks:

The libvirt qemu hypervisor driver has long supported protecting disk devices from concurrent use via libvirt's lock manager interface. Xen used to support the same functionality in the old xend toolstack, but dropped support in the new libxl toolstack. The Xen community decided, rightly so, that this functionality is best provided by a higher-level management tool, e.g. libvirt.

Goal:

Objective

The current approach to having new hardware support and features in SLE kernels it to integrate changes to individual drivers from the mainline kernel back into the SLE kernel. The Linux Kernel Backports project (https://backports.wiki.kernel.org/) in comparison has an approach which consists in adding a shim layer between unmodified mainline drivers and older kernel interfaces. This project has its roots in wireless drivers. It currently supports only a handful of old ethernet adapters.

Due to the newly appointed PM of SLERT 11 SP4, I would like to try out the SLERT 11 SP3 to experience the REAL TIME features so that I can talk and share the knowledge to team and other people

LVM support for Guix System Distribution

Have a look at the library implementation and its API.

The webVTT standard (nearly the same as the older SRT subtitles) allows to add subtitles to a video. We could use this in openQA to show which keys were pressed at that point in the video, in which line of code we were or on what event we waited. This could make debugging easier and might be instructive to users, too.

I would like to have a programming language that has the performance characteristics of C, but integrates some programming language features that I like from other languages. My first goal would be to start with a language that is very limited in scope and compiles directly to C, and step by step add to it.

For Hibernate Signature Verification - HMAC version, I need a hash algorithm in EFI stub environment before ExitBootServices() to mix / mess random seed from different sources (rdtsc, rdrand...) for generating the HMAC key to sign the hibernate image in runtime environment.

Nailed is a Sinatra app which currently shows Bugzilla, Github and Jenkins [WIP] data. The data gets fetched/refreshed by a ruby command line tool in the background.

I would like to learn Salt by converting ansible scripts to salt states. Current ansible scripts do some QA tasks on cloud nodes, so i thought it would be a good idea to convert them to salt after reading salt tutorial.

Some customers are still stuck in a world of 32bit. On ARM64, we have two options for those poor folks:

posixovl is a FUSE based successor of the old UMSDOS. It has a goal to provide POSIX file system functionality on top of vfat. Its code is nice and well written, but its feature set is not complete yet. It just supports: POSIX modes and user/group, hard and symbolic links, device nodes and named pipes.

While auto-mounting a VFAT volume in a desktop environment, there is no way to select required mount options for the particular volume.

Displays your openQA instance status, the feature/behavior should had at least like the list below,

Continue on the started CHDK (Canon Hack Developer Kit) for libgphoto2 support.

Create a user interface useable with a see through head mounted display. The display was created from some Chinese video glasses and has a low resolution (320x240) which requires a optimized user interface that also is useful when using it hands free.

In the YaST installer, make disk encryption method, mode, key strength, random source etc configurable.

Rust, the new language from Mozilla Foundation, is a modern systems programming language focusing on safety and speed. It accomplishes these goals by being memory safe without using garbage collection.

My home server, and my other box hosting https://sysrich.co.uk are both in need of a bit of a refresh

Our books are also available as regular software packages such as 'sles-manuals_en'.

this work has experimented with zeromq sqlalchamy and multithreading in python to make a rich tool for syncronisation of your music collection with media devices.

whenenv is designed to keep the branching involved in build and functional test scripts from growing out of control.

dropwatch is a utility which can help you to see if data is been dropped in linux network stack.

DRBD refers to block devices designed as a building block to form high availability (HA) clusters.Also possible to combine multiple devices driver for Linux(MD) and the network block device(NBD) to achieve similar functionality.

There is a ramdisk block device (brd), and there is a null multiqueue device (nullblk). The one can do I/O, but doesn't use multiqueue, and the other does multiqueue but cannot do I/O.

We currently work on a consistency model for upstream livepatching infrastructure. We use something called a fake signal to speed up a finalization of the patching process. I'll port the implementation to kGraft in SLES which should allow to remove immediate patching since it has recently proved to be problematic...

I have an IRC tab open in pidgin and an adjacent XMPP tab; the latter one displayed with focus. When a new XMPP tab opens in background (with a message incoming), the IRC tab steals the focus but not the display. It brings annoying situations when I sometimes send something accidentally to the IRC instead of XMPP, not noticing that I don't have focus.

We from the public cloud dev team regularly upload generic and product images to be available in public cloud systems like Amazon EC2, Google Compute Engine or Microsoft Azure. The task of uploading stuff there is not only about having the tools it's also about having the right environment which provides account credentials as well as access to the image when they are built in the buildservice. Also the location from where the upload happens can make a difference in performance.

VNC protocol transfers key symbols (= basically characters), not key codes (= "coordinates" on keyboard). Therefore pressing the same keys may result in sending different commands over VNC depending on the keyboard layout and state of modifiers on the client side. The server however can not directly send the key symbol to the application, it must instead find or create key code that will translate to that symbol and send that.

The disassembly in gdb is not ideal. The binding with source code lines is weird (even crash, which does use gdb beneath, does that better), I don't see the jump targets; furthermore, there's a lot more informations hidden in the DWARF2 which may be of some interest - like which code is inlined, or which register/stack address should contain some variable.

Today OpenQA mostly runs on virtual machines, but it can get really tricky to find bugs triggered by real hardware. There are only few interfaces required to interact with a machine though:

ARM64 is become more popular on different markets, but obviously lots of pepople didn't have the hardware platform, and fastmodel is helpful for people to play with ARM64 environment, furthermore, we can run different software platform on it, such as Cloud, HA, Virt and OpenStack.

The zypprepo was written around 3 years ago, and was based on the yumrepo built-in type/provider. Nowadays zypprepo misses a lot of functionality, which will be automatically inherited if it gets rewritten to be in sync with the current code of yumrepo (as also discussed in its issues #5 and #9). If time permits, solving issue #4 would be also really useful.

I previously created a semi-auto test script(*) for MOK. The script controls the QEMU virtual machine a pre-setup image and performs two simple test cases. It's tedious to setup the images for every SLE and openSUSE. My goal is to write a script to automatically set up the virtual machines and images and do a full test. I would also like to set up a test for weekly-built OVMF. openQA might be a good reference.
