New DB2 appliances are now available in SUSE Gallery, as seen in the search results shown below.

For quite some time the DB2 Express-C appliances (32-bit, 64-bit) have been available in SUSE Gallery. Without any publicity, these
appliances have been found by a relatively large number of Gallery users, who have
downloaded or cloned these to build new appliances. The great thing about these appliances

Today our SUSE Appliance Workshop week ended, so I want to write down a little bit of
what we did this week. “We” means a teammate of mine
(Johannes Renner) and I continued our work on the SUSE
Studio integration into SUSE Manager. We started that with a slightly bigger team
at the workshop 6 month ago but with the end of this AWS, we have reached a state where we
want to present it to the public (that’s you ).

As you might already know, you can create virtual machines with SUSE Manager by
installing them with AutoYaST or Kickstart on a virtual host.

We thought, we have this really great SUSE Studio, where you can build VM images very
quickly, so why not using SUSE Manager to deploy those Studio images? So here is what we
did.

The version control system (VCS) debate is one of the less heated “holy wars” in the Linux/Unix world. Most of the conversation revolves around Git vs. Subversion vs. CVS, but other systems may be a better fit for your needs. For instance, Mercurial is written in Python and C, which makes it easily hackable if you need some functionality the project doesn’t offer already. It’s also fast. And it has other advantages that make it the choice of popular open source projects such as Mozilla, OpenOffice.org, Dovecot and Vim.

I read somewhere an interesting comparison that said “Git is McGyver, Mercurial is James Bond”; in other words, while Git is a collection of tools like git-pull, git-merge, and git-checkout that do most everything except repair your sink, Mercurial is one thing, does one thing, and does it well. And it’s easy to learn, too. (…)

There is a lot of debate over whether or not one should defragment file systems on Linux. Frankly, in most cases fragmentation of Linux file systems is probably not a problem. However, in a very few cases fragmentation might be a problem. When such a scenario has arisen is up to the reader of this article to decide. Recently here at ERACC we experienced access / speed degradation of the XFS file system on a heavily used /home partition. Part of the problem was that the file system was over 90% full. Another part of the problem was when we checked it with xfs_db the file system was roughly 20% fragmented. Besides cleaning up the file system by deleting and archiving old data from user’s directories, we came up with a defragmenation strategy for the entire server. This script is the result: (…)

The libbluray project put out its first official release a few weeks ago. This open-source (GNU GPLv2) library is intended to support Blu-Ray disc playback by media players such as VLC and MPlayer.

The libbluray 0.21 release is the first from the project and it happened on the 30th of November. This release hasn’t been widely publicized and I just happened to know about it this morning from an indirectly-related message on another mailing list. This project was born out of the Doom9 community and has been under development since 2009.

There aren’t many details on the 0.21 release but the VLC announcement simply states: “VideoLAN and the libbluray developers would like to present the first official release of their library to help playback of Blu-Ray for open source systems.” (There also isn’t any change-log or useful documentation distributed with the libbluray package.)

Well, here we are, another year almost done for. Time to look back and take stock of the year that was. You know what? It turns out that 2011 was a banner year for open source projects. So much so, that picking the 10 most important was pretty difficult.

So what do I mean by “important,” anyway? Clearly, it’s not just projects that are widely used. That list would be just too long to even contemplate. You’d have to include Apache, GCC, X.org, Debian, Fedora, openSUSE, Linux Mint, not to mention a bazillion and one libraries and utilities that we depend on every day.

So to judge importance, I looked at projects that are influential, gaining in popularity, and/or technical standouts in new areas. In other words, projects that are even more noteworthy than the other noteworthy projects. This means that many projects that are crucial didn’t make the list. And now, in no particular order, the 10 most important projects of 2011. (…)

It’s been a long, strange trip for SUSE. What started in 1992 as a small German company (SUSE was an acronym derived from “Software und System Entwicklung,” or “software and systems development”) with a derivative of Slackware Linux became a mighty Linux distribution in its own right. Money problems led to a sale to Novell in 2003, which had its own share of troubles.

Finally Novell was sold to Attachmate in a deal that closed in April of this year. Attachmate then decided to spin SUSE off into its own business, and tapped Nils Brauckmann as president and general manager of the unit.

To get a sense what SUSE is in for in 2012, I talked to Brauckmann this morning. Brauckmann’s involvement with SUSE started with Attachmate’s purchase, so the first time we spoke was earlier this year just after he took over the role. This time I found him much readier to discuss details of the SUSE strategy, if not every minor product detail. (…)

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. (…)

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. (…)

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

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. (…)

First, I must reiterate that this blog in no way is intended to be explicitly technical
or even well organized. Rather, it is meant to be more conversational. So in this posting
I’ll be stating my impressions now of the recently released 12.1 and some notes to new
users.

Honestly I have very mixed feelings about this release. But when you consider the
complexity of all the things a Linux distribution entails, with all of its technologies and
software this should ultimately be no surprise. Likewise with bugs; considering the
complexity there will of course be bugs. 12.1 offers a lot of new technologies, very little
of which I actually care about or find personally useful. Bugs… it seems like this release
is especially buggy. However I don’t think that is actually the case, but rather that some
of the bugs that have cropped up are just a bit more “in your face” than some other bugs
that have cropped up. Some of these I ran into myself, but I certainly can’t ignore the many
many improvements to the core technologies and software. (…)

This is my fourth journal entry for openSUSE 12.1 and it has been two weeks of
operational use on both my Thinkpad and home PC. Here are some additional minor frustrations
and some workarounds… and yes, I have posted on the openSUSE forums (just in case you’d

Boot 12.1 using the old System V init

In my first journal entry, I complained the lack of “chattiness” during boot since the
adoption of Systemd. You can easily switch to the old System V init on boot. At the grub
boot loader screen (usual 8 seconds delay) and before you hit Enter to boot, press the F5 button to switch from default to
System V. Now, press Enter to boot and press
the Esc key during the splash screen to see the familiar
System V init messages.

openSUSE is one of the most popular desktop distros available. This time around it’s version 12.1 that has been released. If you aren’t familiar with openSUSE then you should know that it comes in KDE, GNOME, Xfce and LXDE versions. For this review I’ve picked the KDE version of openSUSE 12.1. I may do a quick look at the GNOME version on Eye On Linux later though.

Speaking of the GNOME version of openSUSE 12.1, I took a quick peek at it to see if the openSUSE had made any significant changes to the dreadful GNOME 3 desktop. Unfortunately, they didn’t though they should have. The Linux Mint developers did a good job on altering the GNOME 3.2 desktop to make it usable; I had hoped the openSUSE developers would do the same. Alas, perhaps they will in the next release. The lack of GNOME 3 tweaks is one of the reasons why I decided to review the KDE version instead.

Okay, enough babble about GNOME. Let’s get on with this review of openSUSE 12.1 KDE. (…)

It’s November again, so what does that mean? It means there’s another new release of openSUSE, and I’m reviewing it.

openSUSE doesn’t really need much of an introduction here. There are a few new things with this release, though. The first is that GNOME 3 has become an official part of openSUSE; this is not surprising considering that openSUSE and Fedora were the only distributions who provided vanilla live CD previews of GNOME 3 before its official release. The second is that the release numbering and schedule have changed. Now, there will be releases in November, July, and March, and they will respectively have decimal numbers “.1″, “.2″, and “.3″ before the number before the decimal point gets incremented by one with the next November release. This means that there will be no more “.0″ or “.4″ releases, and that the jump from, for example, version 13.1 to 13.2 will be just as significant as the jump from version 12.3 to 13.1. (…)

I was curious to try out OpenSUSE 12.1 not just because the buzz on it is that it’s a great release, but also because it presented a chance to kick the tires on GNOME 3, which I still hadn’t worked with.

I tested it on my ThinkPad T43 (on the actual machine and not in a virtual one) and it installed with no problems. Everything worked perfectly out of the box (as a side note, on a recent edition of the Tux Radar podcast, host Jonathan Roberts credited improvements in the Linux kernel in making non-Ubuntu distributions competitive hardware-wise; where Ubuntu found early success getting hardware to work, now the kernel itself seems to handle a lot of that heavy lifting for distributions).

OpenSUSE with GNOME 3 looked great. Everything worked. Everything felt fast, even on an older machine with 2GB RAM. (…)

openSUSE 12.1 is the best openSUSE ever as far as I can tell — whether it be Gnome 3 or KDE. Interestingly, openSUSE is the major contributor to the Gnome project, yet its KDE implementation is considered to be the finest integrations.

Being an Ubuntu user (and apt-get fan), I never flirted with openSUSE much. I did try it every time a new version comes out, but from a home user’s point of view it was more work than Ubuntu and the pay off wasn’t that much so I stayed away from it. But everything has changed with version 12.1. It is much more stable (compared to Ubuntu 11.10) and useful for me.

I love Gnome 3 (thanks to the shell-extensions), yet I needed something for those who are not comfortable with Gnome 3 Shell and want a windows like environment. KDE always fascinated me and I thought of giving KDE a try on openSUSE.

Last week we enabled one-click upgrade of old openSUSE appliances tojust
released openSUSE 12.1. The upgrade works the same way as with
previous versions. Just open your old 11.4 (or even 11.3 or 11.2) appliance, go to
the Start tab and click on the Upgrade button in the bar at
the top.

How does the upgrade magic work? Generally Studio tries to change repositories to their
12.1 equivalents and sometimes adds or removes few packages to ensure everything works
smoothly. You can see what exactly was done in the log accessible from the bar at the bottom
of the Start tab.

Sometimes the upgraded appliance will need few tweaks to work. Just inspect the log, see
what was changed, and apply any additional adjustments. Let us know what you had to do on
our forum or <studio-users@suse.de> mailing list so we can improve the upgrade
in the future.

If you are not satisfied with the upgrade, you can always revert to original version by

Having your head in the clouds and managing virtual machines (VMs) which run there is
one thing, really getting there is another. An often neglected step in cloud discussions is
the cloud on-ramp, or How does the VM providing the needed
functionality get there in the first place? Also frequently ignored is the
question of What’s inside the VM? Maybe these questions
are “ignored” as they are inconvenient and not necessarily easy to answer. Similar to
driving a car on the highway – once on the highway going along with the flow of traffic is
easy, but navigating the on-ramp poses a set of challenges that make many uncomfortable.

The on-ramp to the cloud can take various shapes. One is to pre-build task specific VMs
(eg. a web server), which is easy with SUSE
Studio and KIWI. If you have
multiple functions that needs to be distributed between multiple instances, you can build
one image each and then launch them in the cloud. (…)

is the most efficient way if we have running system and do not want to waste a cd/dvd. This
also the most efficient way ifý we have prior versionýand want to upgrade or clean install
running system directly through the network. We can use a brilliant script called setupgrubfornfsinstall.

How to use this small script to fit with our requirement ? (…)

VirtualBox is one of the tools that are used for Desktop Virtualization : running an OS
within the OS. VirtualBox usually installed on the operating system that already has the
VirtualBox GUI to manage it. But, how to manage VirtualBox without VirtualBox GUI?
VBoxHeadless is the answer if we want to install VirtualBox on minimal Linux server and
manage it via Browser.

I’m using openSUSE 12.1 64 bit on this tutorial but the steps can also be applied to
earlier versions (11.x) as well as on SLES 11 SP1. I also use VirtualBox for All
distributions binary package, although for openSUSE we can also use an RPM-binary package.

In short, Air Video is
a client-server product that streams, via live conversion, videos of many formats to any iOS
device (eg iPhone, iPad etc).ý The server software is free-of-charge but only runs on Mac
OSX and Windows.ý The client is also free-of-charge for iOS devices but “crippled”.ý If you
like the solution, you pay for the client.

Since the Air Video Server is written in Java and uses a customized version of FFMPEG,
it would be possible to run it on Linux.ý The folks behind Air Video though supportive but
are NOT offering official support for Linux.

I have been successful in making Air Video Server (AVS) work on openSUSE 11.3, 11.4 and
12.1. Here are the steps: (…)

German company open-slx
has announced the release of the Balsam Enterprise Open Build System (BE-OBS), a distribution development platform
for Linux software. The system is a commercialised version of openSUSE’s Open Build Service which automates the build
and release process for Linux software. openSUSE’s OBS is used by SUSE and openSUSE, by
other companies such as Dell, Cray and GENIVI, and projects including MeeGo. BE-OBS is used
internally by open-slx to construct their own Linux products, which has also enabled the
company to develop its own in-house expertise.

The BE-OBS uses a cluster of systems with load-balanced build agents to enable building
and packaging, testing and release, and distribution and maintenance. It is suitable for
building custom Linux distributions, dedicated software stacks, cross-platform applications
and virtual appliances. BE-OBS is able to automate compilation from a single codebase
targeting different hardware architectures, including 32- and 64-bit x86 and ARM, and using
different operating systems including SLES, RHEL and CentOS. (…)

Nice and positive review of openSUSE 12.1 on the Linux Action Show on 20th Nov 2011. The
YouTube video is embedded below… you may fast-forward to 30:10 where they finally got down
to the review of openSUSE 12.1.

Most interesting (the best) comment on that YouTube page was from Jos Poortvliet (our
openSUSE Community Manager), “VERY nice review guys! Fun to see how opinions on openSUSE
have changed in the last year – from ‘meh, yeah, is that distro still alive?’ to the
awesomeness now :D If you ever wanna talk about it with me – I’d be happy to be on the
show…”

As with most things in life, its all about perception and goodwill. openSUSE 12.1 is
polished and enjoyable but a number of the great features mentioned, including SUSE Studio and openSUSE Build Service, have been around for a
while… anyway, I’m just happy & enjoying the goodwill towards openSUSE. :)

Major updates have been coming fast and furious in the world of
Linux distributions this fall, and this week is no exception. Now joining the ranks of
Ubuntu 11.10, Fedora 16 and many others is OpenSUSE 12.1, which on Wednesday made its
debut.

OpenSUSE is currently the fourth most popular Linux distribution on DistroWatch, behind just Mint, Ubuntu and Fedora. I last wrote about OpenSUSE back in March, shortly after
its last major version, 11.4, arrived on the scene. As I noted then, the free and open-source operating system offers a lot of compelling
features to explain its popularity, including stability, power and ease of use.

With this new release, however, OpenSUSE brings even more to the table — not to mention
a new numbering scheme, which is why it’s now 12.1. Ready for a look? Here’s a small
sampling of what OpenSUSE 12.1 has to offer. (…)

This tutorial shows how you can set up an OpenSUSE
12.1 desktop that is a full-fledged replacement for a Windows desktop, i.e. that
has all the software that people need to do the things they do on their Windows desktops.
The advantages are clear: you get a secure system without DRM restrictions that works even
on old hardware, and the best thing is: all software comes free of charge.

I want to say first that this is not the only way of setting up such a system. There are
many ways of achieving this goal but this is the way I take. I do not issue any guarantee
that this will work for you! (…)

We were never really excited about openSUSE, but 12.1 is well
positioned to change this: it adds some state-of-the-art technology to the highly polished
desktop openSUSE is known for…

OpenSUSE 12.1, you say? Did we miss 12.0 then? No, this is the first release in the
distribution’s slightly altered release numbering: from now on openSUSE will not have a .0
release but only .1, .2 and .3 releases. Because the distribution is following an
eight-month release cycle, from now on the November release will always be the .1 release,
the July release the .2 and the March release the .3. (…)

You may already know, but openSUSE released
v12.1 of the community distribution this week. With a new number before the decimal point, I
thought it would be a good time for a fresh, clean install on my aging laptop. I could just
upgrade my existing v11.4 installation, but I like to see what the new install looks like
from time to time. Doing a clean install also means I can share the process with you
too.

Clean installs do require a bit of preparation, though. You will be wiping your
partitions, so you want to preserve your existing data, and a bit of your configurations
before embarking on a new install. In this post, I’ll share what I did.(…)

Welcome to the second part of our series, a part that will focus on sed, the GNU version. As you will see, there are several variants of sed, which is available for quite a few platforms, but we will focus on GNU sed versions 4.x. Many of you have already heard about sed and already used it, mainly as a substitution tool. But that is just a segment of what sed can do, and we will do our best to show you as much as possible of what you can do with it. The name stands for Stream EDitor, and here “stream” can be a file, a pipe or simply stdin. We expect you to have basic Linux knowledge and if you already worked with regular expressions or at least know what a regexp is, the better. We don’t have the space for a full tutorial on regular expressions, so instead we will only give you a basic idea and lots of sed examples. There are lots of documents that deal with the subject, and we’ll even have some recommendations, as you will see in a minute. If you require futher assistance please visit our Linux Forum. (…)

In this case, the title might be a little misleading. And that is because awk is more than a command, it’s a programming language in its own right. You can write awk scripts for complex operations or you can use awk from the command line. The name stands for Aho, Weinberger and Kernighan (yes, Brian Kernighan), the authors of the language, which was started in 1977, hence it shares the same Unix spirit as the other classic *nix utilities. If you’re getting used to C programming or know it already, you will see some familiar concepts in awk, especially since the ‘k’ in awk stands for the same person as the ‘k’ in K&R, the C programming bible. You will need some command-line knowledge in Linux and possibly some scripting basics, but the last part is optional, as we will try to offer something for everybody. Many thanks to Arnold Robbins for all his work involved in awk. (…)

PHP is an open-source server-side scripting language and it is a widely used. The Apache web server provides access to files and content via the HTTP OR HTTPS protocol. A misconfigured server-side scripting language can create all sorts of problems. So, PHP should be used with caution. Here are twenty-five php security best practices for sysadmins for configuring PHP securely. (…)

There are many occasions where you need to create connections to machines and services that are protected by firewalls because it is appropriate to adequately protect them, but for which the creation of a VPN becomes an excessive burden.

For this reason, the ability to port forwarding via SSH is very useful for creating an encrypted tunnel from one machine to another, allowing you to enable only local access (such as a MySQL only listens locally) safely, with the only the problem that in case of problems, the SSH connection (and its tunnels) could fall.

”

Here goes a quick and valuable tip people don’t usually know, or at least a couple of
friends of mine were not aware of. The two keywords will be SOCKS and SSH.

Connecting over to a remote server, one can bypass unauthorized access blocked by
usually our network firewall. The most common examples given are restricted access to
Facebook, MSN or torrents. We can also have unlimited access to all kinds of contents thanks
to the nice sysadmin managing the network who puts no barriers whatsoever, but we may not
trust him or the network users to permit unencrypted data flowing openly. Having some way to
establish an encrypted connection to a known network who we trust, or distrust less, and
tunneling over it would be safer. This is where SOCKS and SSH can be much of helpful!

Linux creator Linus Torvalds spoke at the LinuxCon Brazil event this week, and had some choice words for makers of proprietary technology, especially Apple and Microsoft. Mashable picked up this dig from Linus at these tech giants, regarding the much discussed secure boot feature that Microsoft is backing, which could lock Linux out of Windows 8 PCs: ““Technologies that lock things down tend to lose in the end. People want freedom and markets want freedom.” Torvalds compared secure boot to Apple’s use of Digital Rights Management (DRM) technology. Notably, Torvalds had a decidedly anti-Apple stance in the comments. (…)

Since the source code is usually available, software under a free or open open source license can be re-used within another software project rather easily. That is, after all, the whole point of FLOSS. But the potential for FLOSS license violations within software projects is, like any other license, always there.

Critics of FLOSS licenses are usually quick to point out that the very openness of FLOSS source code actually promotes more license violations. Protect yourself, these critics urge, and avoid FLOSS altogether–or at the very least purchase commercial compliance services and products. (…)

Following two release candidates and a slight delay, the openSUSE project has
published version 12.1 of its Linux distribution. The major update to the openSUSE operating
system introduces a number of platform changes and new features. Based on the 3.1 Linux kernel, openSUSE 12.1 offers a choice of the GNOME 3.2 or the KDE 4.7
desktop environments and is the first distribution to ship with colour management tools for
both. Users looking for a minimal, lightweight desktop can alternatively select from either
Xfce or LXDE desktops which, according to the developers, haven’t seen any major feature
updates since the last openSUSE release. (…)

The OpenSUSE project released OpenSUSE 12.1, featuring Linux 3.1, GNOME 3.2, KDE 4.7,
plus support for KDE’s “OwnCloud” cloud platform. OpenSUSE 12.1 introduces the SystemD
configuration utility and Google’s Go programming language, and integrates a Btrfs-based
“Snapper” tool for rolling back system updates and configuration changes.The first
beta of OpenSUSE 12.1

When Novell was bought by Attachmate, people wondered if Novell/SUSE’s community Linux distribution, openSUSE, would even survive. Now, we know, openSUSE lives.

The openSUSE Project has released the latest version of its popular Linux distribution openSUSE 12.1. In a statement, Jos Poortvliet, openSUSE community manager for SUSE, said, “OpenSUSE 12.1 represents more than eight months of worldwide effort to create one of the industry’s best Linux distributions. The openSUSE distribution and its thousands of open source applications are the result of contributions from individual testers, writers, translators, usability experts, artists, ambassadors, packagers and developers having a lot of fun working together to create a uniquely powerful set of tools and capabilities.”

So what does that mean? Well, among other things even more so than Ubuntu, openSUSE is embracing the cloud. (…)

The OpenSUSE project has released its next stable version, a.k.a OpenSUSE 12.1. It includes the Linux kernel 3.1, tons of enhancements for use with public and private clouds and the cool new Tumbleweed tool, a project conceived by SUSE kernel engineer Greg Kroah-Hartman.

openSUSE includes a feature called “ownCloud,” which is a filesharing alternative to services like DropBox. ownCloud has two downsides: it takes some skills to implement it and it doesn’t keep the files persistently on your computer to access them offline. openSUSE solves that with its new mirall tool which eases deployment of ownCloud and creates a local folder in which it synchronized local and cloud files.

openSUSE, the community developed Linux distribution sponsored by SUSE, has released version 12.1 today. At first glance, openSUSE 12.1 is pretty much in line with recent releases from Fedora and Ubuntu: GNOME 3.2, systemd, etc. But a closer look starts to reveal some real divergence between the various Linux offerings today. For example, while Fedora 16 allows you to choose btrfs for your filesystem, openSUSE 12.1 uses btrfs by default. There’s a number of other interesting advancements packed in this release, too. (…)

The openSUSE Linux distribution is out with a new release today, providing users with new desktop, cloud and backup features.

One of the key new features in the openSUSE 12.1 release is the Snapper tool that helps users to take full advantage of the Btrfs filesystem.

“Btrfs adds the ability to do rollbacks on file changes,” openSUSE Board Chairman, Alan Clark told InternetNews.com. “So if someone accidentally deletes a file, I can use Snapper to rollback and recover that file.” (…)

The openSuse team has announced the release of version 12.1. I have been playing with the RC for a while and found it exremely stable. We are working on a review of openSuse 12.1 and will be publishing it soon. Keep an eye on our Google Plus page for the review.

openSUSE 12.1 comes with the new GNOME Shell 3.2. Notifications are much nicer, you can now configure your online accounts in one place and Shell handles multiple-screen setups better. Among the features is color management, something GNOME shares with KDE where openSUSE is the first to integrate the Oyranos color management system. Also new from KDE is Apper, an easier-to-use PackageKit front end. (…)

This is the favorite time of the year, it’s like Christmas for a GNU/Linux user. This is the time of the year when most Linux distros release their latest versions. We have already played with Ubuntu 11.10, Fedora 16 and today openSUSE 12.1 arrived. I have been casually using openSUSE 12.1 (RC) for a while and am quite comfortable with it — a compliment as its coming from a long-time Ubuntu user. If I look at my pattern I have been switching between Ubuntu 11.10, Fedora 16 and openSUSE 12.1 quite a lot recently. My Google + page is full of my experiences with these three OSes.

I never was an openSUSE user. I completely shifted to Linux at the same time when Novell signed that infamous deal with Microsoft which tried to ‘validate’ Windows maker’s base-less and false claims that Linux infringes upon its patents. I distanced myself from openSUSE after that deal. Now, with Novell gone and Microsoft shifting focus to Android (Barnes & Nobel just exposed that Microsoft’s Android claims were bogus) openSUSE appears to be back as the community driven project, and I am back too.

I don’t know how many of you have 3G hardware built into your netbooks, but as you can
probably guess its not always straightforward. Frankly, it took me months to figure out what
I was doing and get it working consistently. Then while I was running 11.4 I decided to give
Mandriva a try (which had some critical flaws) and so I reinstalled openSUSE. Now all of a
sudden the process I had figured out so well, didn’t work as it should have. I was tired of
reinstalling and trying to figure it out, so I figured I would just wait until 12.1 came out
and pray that the fresh install of it would fix my problem.

So now I have installed 12.1RC2. And at first it looked encouraging, though the hardware
wasn’t accesible quite I could however go into the NetworkManager Mobile Broadband tab to
set up a connection and it would show me Verizon as selectable. That is what the crucial
problem I have been having is about; Verizon is not selectable for some odd reason. Maybe,
just maybe I somehow did get the firware mixed up but I severely doubt it since I remember
having to go through this process a few times.

Overview & Uses

Screen is a great tool, and highly recommended, tool for any Linux user. It provides a Terminal environment that can withstand network disconnects, random computer restarts, power outages at home and more. With screen you can be assured that if PuTTY, or whatever SSH Client you use, closes you will almost never lose your work. Sadly this is not true for a server restart, as far as I’m aware, but it still provides amazing possibilities. In this wiki you’ll find instructions for installation and customization that will not only enhance screen for the best, but will also make it more enjoyable to use. If you’re like me, once you start to use screen you’ll never go back to mundane old terminal. Please note that all of these steps were done on my system, which I will provide screenshots for, but this is not the only way to set your screen environment up. To add to that, there are also numerous other alterations you may make to your screen environment. Feel free to play around with it and see what you come up with. (…)

As promised, starting with this part of our C development article, we will get started with learning, without further introduction. I couldn’t find no better way to start other than this, because types, operators and variables are an essential part of C and you will use them all the time when writing your own programs. For example, you can write a simple C program without defining your own functions, but it’s harder to do that without some variables, unless you wanna stick to “Hello, world!”. A variable is nothing more than a location in memory holding a value that can be altered (hence the name). But before you declare a variable you must know what kind of value you want it to hold, and here you will use types. And in order to
operate
on those variables, you’ll need…operators, of course. I intend to make this course as concise as possible, so I recommend attention and as usual, practice. Any questions can be addressed on our forums, and we will do our best to answer them. (…)

This tutorial shows how you can serve CGI scripts (Perl scripts) with nginx on OpenSUSE 11.4. While nginx itself does not serve CGI, there are several ways to work around this. I will outline two solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second solution uses a CGI wrapper to serve CGI scripts.

If your network includes a domain controller (either a Windows computer or a Samba server), you can use its user database instead of or in addition to maintaining local login users in a Linux computer’s local account database. Doing so requires using a set of tools known as Winbind. This toolset can be handy even for Linux computers that don’t run Samba to share files or printers; users with Windows domain accounts can log in at the console or use SSH to access Linux-only features, use POP or IMAP mail servers with Windows domain authentication, and so on.

We all know that lighting matches near a combustible substance like gasoline is not a good idea. Yet people go up in smoke every year.

Similarly, putting a developer and a customer in the same room can have a combustible effect. Many developers tend to be very direct, and talk in technical terms the customer can’t comprehend. They sometimes have very little patience for customers who send mixed message about their requirements.

As a result, many developers (and their projects) go up in smoke every year as well. (…)

Hiring a junior Linux System Administrator can be a challenging task, especially if you are interviewing for someone who is above your own Linux skill set! How do you know for sure that they are going to be any good at what they say they can do? What are the best interview questions to ask a junior Linux System Admin?

In our experience, the best way to gauge an employees skill set is to put them in front of a command line interface and have them execute a number of straightforward tasks. Oftentimes, candidates will say that they have strong skills in Linux, but when confronted with an actual problem, they don’t have the “tools” to fix it themselves.

Maqetta is an open source project that provides WYSIWYG visual authoring of HTML5 user interfaces. The
Maqetta application itself is authored in HTML, and therefore runs in the browser without
requiring additional plugins or downloads.

be handed off to developers, who can then transform the application incrementally from UI
mockup into final shipping application. (…)
