Will Stephenson: openSUSE Board Election – My Manifesto
TL;DR: openSUSE as a project needs to raise its game, and the next openSUSE Board can guide the project to agree a tight set of goals for our releases and work to a higher standard on them. Otherwise we risk being an undirected mess of pet projects, bikeshedding discussions and bickering tribes.

[Look at plymouth for splash during boot (Score: 210)](https://features.opensuse.org/305493)
I wanted to open a fate feature about this when I first heard of plymouth, but reading //fedoramagazine.wordpress.com/2008/10/21/interview-fedora-10s-better-startup/ really makes me think we should go this way.
Ray’s comment starting with “Every flicker and mode change in the boot process takes away from the whole experience.” is especially interesting. Is it okay to track the “don’t show grub by default” here?

[1-click uninstall (Score: 177)](https://features.opensuse.org/305305)
An easy way to remove Software! For example: you installed an application with “1-click install” (which will install all the packages that you need), there should be an easy way (also with 1 click) to remove what you have installed with that 1-click operation… in another words: an “1-click Uninstall” to remove installed software (dependencies and packages included).

[Update to GRUB v2 (Score: 174)](https://features.opensuse.org/308497)
Every single bug or feature that anyone has developed for GRUB 0.97 has been rejected by the upstream project in favor of using GRUB 2. There has been resisitence in the distribution community to switching boot loaders, but this stalemate isn’t going to go away. The code itself isn’t well written or well maintained. Adding a new feature involves jumping through a lot of hoops that may or may not work even if you manage to work around all the runtime limitations. For example, a fs implementation has a static buffer it can use for memory management. It’s only 32k. For complex file systems, or even a simple journaled file system, we run into problems (like the reiserfs taking forever to load bug) because we don’t have enough memory to do block mapping for the journal so it needs to scan it for every metadata read. (Yeah, really.) (…)

[Remove "tracker" from lxde](https://features.opensuse.org/313038)
As LXDE is intended to provide a LIGHTWEIGHT desktop environment, unnecessary bloats like tracker should not be provided with it.
Unfortunately the openSUSE pattern for LXDE contains Brasero, which automatically brings tracker as a dependency.

[Prettier boot process](https://features.opensuse.org/313040)
Right now, the boot process looks kinda ugly. systemd makes a jumble of codes and the splash screen is boring. For 12.2, the pretty green dones and the red faileds should be brought back to the boot process and the geeko logo should do more than roll it s eye a little. Have it do something, like shift color sort of like a progress bar or walk around as the machine boots up.

[Show screenshots to help user choose which desktop to install](https://features.opensuse.org/313047)
Currently, when the user chooses the type of Desktop they want to install they are presented with a rather ‘boring’ menu with lots of text, describing a little about GNOME, KDE, and how they get to choose.
I would like to see screenshots, possibly even a slideshow, of at least GNOME and KDE if not XFCE & LXDE for users to see and help them make their choice about which desktop environment they wish to install.

The Unofficial openSUSE Guide is one of the greatest resources to new users. By making it front and center, it will help new users not be so frustrated, and help us whom support them not be so frustrated.

[Simplified install workflow](https://features.opensuse.org/313062)
The install work flow should be as simple as possible. Therefore it should consider the view of a non IT person and only ask real key questions. Why are we asking a user about which desktop environment they like to use? A Linux beginner doesn’t care about KDE or Gnome.
Even the summary before the installation should be as comprehensive as possible in the default mode. Network configuration isn’t required in 80, 90 or more % of the use cases. If there we get an IP address offered by DHCP don’t bother the user even with a summary. Most users intend to use their computer as easy as possible. Therefore less questions asked will result in a smoother experience.
This issue had been initially discussed as part of this thread //lists.opensuse.org/opensuse/2011-12/msg00382.html

Last Friday we had a 12.1 launch party in Prague. This time it was in SUSE office. Why so long after the release? We wanted to make sure to have some new shiny factory made DVDs for our guests. And as we waited, it happened to be nearby St. Nicolas day. For those of you that don’t know Czech traditions, on St. Nicolas day, we have people dressed as St. Nicolas, devil and angel going through the city, visiting children. Good children will get some snacks from St. Nicolas as a reward, bad children will get potatoes or coal from the devil as a reward. We wanted to exploit this tradition a little bit and thus every guest got a little gift from St. Nicolas. As they were our community, sure they were all good. But just in case, I dressed a little bit devilish…

[h-online/Thorsten Leemhuis: Kernel Log: Coming in 3.2 (Part 3) - Architecture](//www.h-online.com/open/features/Kernel-Log-Coming-in-3-2-Part-3-Architecture-1390730.html)
Optimised assembler code paths accelerate SHA1 and speed up the Blowfish and Twofish encryption algorithms. The next scheduled Linux kernel release avoids a cache problem found in AMD’s latest processors and includes new and extended drivers for Intel CPUs.
In keeping with the usual weekly release rhythm, Linus Torvalds issued the fourth release candidate of Linux 3.2 last Friday. It contains fewer changes than the two previous RCs, and Torvalds said that “things really are calming down pretty nicely”, adding that it is even “suspiciously quiet.” With the development of Linux 3.2 in progress, the Kernel Log is continuing its “Coming in 3.2” mini series. After describing the advancements in the kernel’s network driver and infrastructure areas and those relating to filesystems, we will now cover the changes relating to the kernel’s architecture and processor support; in the coming weeks, further articles will discuss the kernel’s infrastructure and drivers.

1. Introduction
The C standard library offers a plethora of functions for many usual tasks. Also there are lots of libraries for extra functionality, like GUI design (GTK+) or database interfacing (libpq). However, as you advance in the C programming world, you will soon find yourself repeating the same instructions in the same order over and over again and that will become time-consuming and inefficient. So you can just wrap all those instructions in a function and just call said function when you need it. Here’s what you’re gonna learn by reading this article, plus some useful tips that will make your life easier. Any suggestions or problems go to the forums, as before. (…)

This is the final article on installing opensuse. To recap we’ve covered Configuring the DHCP Server, Installing Apache on OpenSUSE, OpenSUSE PXE Boot and today we’ll be tackling how to automate an install with AutoYaST answer files.
The final part of our installation jigsaw puzzle is to create the answer file, in SUSE this is known as AutoYaST. If we were only ever to install one server or one desktop then maybe we could do without answer files; however where we need to install a few or many then AutoYaST provides us with an unattended installation:- a build script to create consistency and compliance we regulatory bodies governing security. In short we need answer files. (…)

[Wazi/Carla Schroder: Shh! OpenSSH Secrets Here](//olex.openlogic.com/wazi/2011/shh-openssh-secrets-here/)
If you routinely use multiple computers, it can be a challenge to keep your data files organized and to manage multiple login IDs. OpenSSH can help you with those tasks. It’s a powerful, secure tool that lets you share files without having to set up a file server, run applications remotely, and perform remote administration chores quickly and securely. You probably already know how to use OpenSSH for file transfers. Here we’ll uncover some less well-known OpenSSH tricks that can make life easier for roaming computer users.
To use the software, you should have the OpenSSH server and client installed and working on all the computers you need to access. In this article I use local for the computer we’re launching an OpenSSH session from, and remote to refer to the computer we’re logging into. (…)

[IBM developerWorks/Paul Ferrill: Scripting KVM with Python, Part 1: libvirt](//www.ibm.com/developerworks/linux/library/os-python-kvm-scripting1/index.html)
Virtualization is standard equipment with most server operating systems on the market today. In the Linux® world, there are two primary choices for server virtualization: the Kernel-based Virtual Machine (KVM) and Xen. KVM is the primary technology that Red Hat and others use. Although Citrix owns Xen, much of the core functionality remains in the public domain.
The Virtual Machine Manager (VMM, or virt-manager) project provides a tool for managing the creation and running of both KVM and Xen virtual machine (VM) instances. VMM is written in Python using the GTK+ library for graphical user interface construction. The real work is done through the libvirt library, which is what you’ll be using for this article series. Although libvirt is a Red Hat-sponsored effort, it remains an open source project available under the GNU Lesser General Public License.
libvirt is made up of several different pieces, including the application programming interface (API) library, a daemon (libvirtd), and a default command-line utility (virsh). For the purposes of this article, all testing is done using Ubuntu Server version 11.04. The Installation and setup section covers everything I did to configure my server for developing the scripts presented here. Part 1 covers the basics of libvirt and Kernel-based Virtual Machine (KVM) virtualization along with a few command-line scripts to whet your appetite. Part 2 will dive deeper and show you how you can build your own virtualization management tools using libvirt, Python, and wxPython. (…)

Dominique Leuenberger: Enhanced typelib based dep generation
A long time ago I posted about our inclusion of an automatic dependency generator for typelib() style provides and requires. The main goal there was to have the various seed and python based programs depending on gobject-introspection based bindings properly require the bindings, which also dragged in the libraries needed.
For the openSUSE 12.2 release cycle we have to push this a little further: As the typelib namespace and version does not grow linear together with the shared library name, we have to split the *.typelib files out of the shared library package.
An example why the typelib files need to be split out from the libraries:
Clutter: the library was renamed from libclutter-glx-1.0.so.0 to libclutter-1.0.so.0, the typelib remained Clutter-1.0.typelib. The upgrade process is slightly ‘messy’ in this case and a bunch of problems could be avoided by splitting the typelib files out. (…)

Masim Sugianto: How to Check, Test and Validate DKIM Records in DNS is Correct and Valid
As I’ve wrote in the article: “10 Tips for Auditing & Improving Mail Server Performance“, Dkim or Domainkeys is one feature that can be used to increase the acceptance rate (eligibility) of email on the destination mail server.
DomainKeys or DKIM signature basically allowing good senders to “sign” a message to prove that it really did come from them. This process is obtained by signing the outgoing mail with a specific code corresponding domain name and identity of the mail server so it is considered valid and convincing as an authorized sender.

While Calligra 2.4 did not make it as part of openSUSE 12.1, its latest beta is available in the KDE:UpdatedApps repository and I hope Tumbleweed will pick it up too. I’m quite excited about this release and I’d like to share why!
Little intro
As you might or might not know, Calligra is the result of a split of the KWord maintainer with the rest of the KOffice team. The ODF based Suite has a wide range of applications. From Krita, the most versatile and usable sketching and painting application on Linux (click for an experts opinion), and Kexi, the most powerful and complete database tool available as Free Software - to Words, Karbon and Stage. These last, as well as all the other applications in Calligra, are far less mature than Krita and Kexi. The team has been limiting their scope, focusing on getting them stable and usable while skipping on features.

Even as the Linux Foundation reports on Linux jobs in the U.S., the global picture seems to be even more encouraging.
That’s the take away from my conversation with Ralf Flaxa, SUSE’s VP of Linux Engineering, who paints a pretty strong picture of worldwide job hiring on the part of SUSE and, presumably, other non-U.S. firms.
As the person primarily responsible for hiring engineers for SUSE, Flaxa has a unique position on the outlook for Linux careers, especially in the European market.

So you want a Linux job do you? Well, according to The Linux Foundation, the jobs are out there. Specifically, Linux jobs are divided up almost evenly between developer, 53% and system administrator. 47%, jobs.

The data we’ve surfaced from our Jobs Board really reflects the importance of common programming languages, as well as areas of great success for Linux–such as Android. Mobile and embedded development skills are extremely valuable in today’s market.

[IBM developerWorks/M. Tim Jones: Evolution of shells in Linux](//www.ibm.com/developerworks/linux/library/l-linux-shells/index.html)
Shells are like editors: Everyone has a favorite and vehemently defends that choice (and tells you why you should switch). True, shells can offer different capabilities, but they all implement core ideas that were developed decades ago.
My first experience with a modern shell came in the 1980s, when I was developing software on SunOS. Once I learned the capability to apply output from one program as input to another (even doing this multiple times in a chain), I had a simple and efficient way to create filters and transformations. The core idea provided a way to build simple tools that were flexible enough to be applied with other tools in useful combinations. In this way, shells provided not only a way to interact with the kernel and devices but also integrated services (such as pipes and filters) that are now common design patterns in software development.
Let’s begin with a short history of modern shells, and then explore some of the useful and exotic shells available for Linux today. (…)

ITWire/Sam Varghese: A tale of two distros: openSUSE and Linux Mint
For as long back as I can remember, GNU/Linux distributions have resembled Windows in one respect - that start menu at the bottom of the left side of the screen.
This is not surprising, considering that most people who move to GNU/Linux are Windows refugees. And one needs some points of similarity in order to ease the transition.
Even when Ubuntu came along in 2004, though the menu was located at the top of the screen, it was child’s play to move it to the bottom. Ubuntu was tracking the development of GNOME, keeping in sync with the six-monthly release schedule of the latter. (…)
