has already
, fixing an issue is a matter ofBURPing
on build.opensuse.org! Find a how-to here.

So go and see for yourself what the next version of openSUSE has in store for you at
our download center.



With the days closing in on us before the next great openSUSE Conference in Nuremberg,
Germany 11-14 September, 2011, we’re seeing a lot of awesome papers being submitted to the
Conference Program Committee.  But there’s still time for you to submit that awesome session
you’ve dreamed of. The deadline to submit your
is midnight July 25th.

What We Are Looking For:

This year’s Conference theme is RWX³.  That means its an open conference in which we all
get to roll up our sleeves and get involved!  We’re looking for that great session that talks
about FOSS projects, openSUSE Community growth, and  workshops that empower our users and
contributors to do more awesome stuff.

Types of Sessions you can apply for

As you can see, the possibilities are endless.  And this year’s conference, which is
always free, is extra special because we’ll be moving to our new location, Zentrifuge, and
co-hosting with the SUSE Labs Conerence.  That’s two for the price of one and one is

What’s Next

  • Submit your proposal here

  • The Program Committee will be reviewing all submissions and making their votes
    before August 1.

  • After August 5, we will announce the accepted proposals and contact you with the
    status of your proposal.

Remember, the deadline is this Sunday, July 24th!



The openSUSE conference “RWX³” is the
place to be for anyone using, working on or taking advantage of the openSUSE Project. No
matter if you use our technology such as the Open
Build Service
, contribute packages to 12.1 or evangelize the world as
an Ambassador, this is your conference. You can also meet a lot of your friends from
other projects like KDE, GNOME, Linux, Samba,LibreOffice and, of course many people from other
GNU/Linux distributions with whom we collaborate on technologies like packaging, appstores or low-level
tools like systemd.


Header PictureGoogle Summer of Code


Short weekly report is short, this week’s achievements:

  • fixed the install/remove simulation bits (it can now tell what packages will be
    removed after applying changes)

  • improved PackageInfo testing (works with both AptCache and PackageKit)

  • found the problem with dynamic/static libs conflict: it is gio statically
    loaded from gtk and then Gio dynamically loaded from PackageKitGlib; loading Gio before
    everything seems to fix the conflict for now;

  • got another round of refactor changes into trunk, thanks to mvo; this way my PK branch is
    one step closer to merging into software-center



Here’s a small summary of the 8th (coding) week. This week I spentmost of my time with
rewriting the working copy code.


  • added support to add and delete packages

  • added some “abstractions” for the tracking file format:currently packages and files
    are tracked in a xml file

  • thought about the package update algorithm. Basicallyit’ll work like this (verfy
    simplified version):

    • perform update in a tmpdir (phase 1)

    • if the tmp update finished, copy/rename all files tothe wc (phase 2)

      Advantage:If the update is interrupted in phase 1 the wc wasn’t touchedat all
      and nothing should be broken.If the update is interrupted in phase 2 the wc is
      _inconsistent_but a subsequent “update” call can resume the update and
      everythingshould be consistent afterwards (in this case only files


  • implement update + commit algorithm

If everything works as expected most parts of working copy codecleanup should be finished
after this week.



Exciting news for the project this week. After solving the problem with the comments and
the tree representation of the sysconfig files in Augeas, there was a big leap in the
project’s progress. By having test data and through debugging i was able to complete the match
algorithm.The program is now able to traverse through two trees / files, make the necessary
matches between the nodes of these two trees and provide the appropriate information to the
later stages. That of merging.

What exactly have been done in the previous week:

  • Tree representation of sysconfig files

  • Matching between two trees nodes completed

  • Sorting of labels (Small Fixes)

  • tree_compare function complete

  • Tree traversal of aug_process_trees ( revisited)

What is for next week:

  • Finish merging functions for aug_process_trees ( I feel optimistic that i will
    surely complete this next week due to the reason that matching was completed)

  • Create first beta packages

  • Test Test Test

  • Improve code



This week I’ve been working on finishing up the ToDo Lists, which did entail writing a new
Item Delegate for the list as the previous method of checking which widget had been clicked
was less than optimal!. I have finished the ToDo List and it will hopefully be merged on
Monday into an experimental branch that I can go through and ensure that everything works as
expected. This will then all be pulled together as a possible version 1.0 of Entomologist,
which is great news!.

I am currently researching possibilities for integrating Cloud Services into the ToDo List
and I plan on targeting an iCal/WebDAV compatible format export to begin with. Once this basic
step is in place I can then look at integrating with various web services and generic
iCal/WebDAV support for servers that use these.

This all leads on to how long I have left of my GSoC, which by my count is 5 weeks(!) of
GSoC Time,but I would like to stick to the soft pencils down date as much as possible so the
final week can be spent ensuring everything works properly. I want to look at the addition of
QML after I’ve integrated some Cloud Sync aspects as I think this would be a really excellent
feature to have.

Here’s a screenshot of the ToDo List on OS X Lion (Which also shows that nothing has to be
done to Entomologist’s code base to make it compatible):


Header PictureStatus Updates

Header PictureDistribution


I’ve noticed the following changes that might interest people using and developing
openSUSE Factory:

Package changes

GNOME 3.1.3

The GNOME team plans to have GNOME 3.2 in for openSUSE 12.1 and thus have updated to the
current development release 3.1.3. They have also started removing old GNOME 2 packages that
are not needed anymore.


Frederic gave an update on
systemd integration. The graphical bootloader allows now to switch during boot between
systemd, SysVinit and also shell code.

Also, Lennart Poettering wrote in his “systemd for developers” series about socket
 where he uses cups as example.


The hal daemon has been dropped from Factory after all users with clean spec files have
been changed to work with the successors of hal like udisk and udev.


Samba is getting updated to 3.6.0, one
of its major features is full SMB2 support.

Linux Kernel Headers

Linux kernel 2.6.38 removed the Video for Linux v1 support and also the file
linux/videodev.h. Since we now use the Linux Kernel 3.0, applications using the old
interface need to be converted. A replacement is libv4l1-videodev.h from libv4l-dev >=

Keeping old kernel(s) while installing new ones

Michal Marek descripes in his blog how it’s possible to configure which kernels to keep installed when a new
one gets installed. With a simple change to the zypp configuration, you can define e.g. that
you always like to keep the latest running kernel when you install a new one.

Upcoming Features

A new page called “upcoming features” has been created to point out new features for the next
release. Please help updating the page with new information.

Policy and tool changes

Directories not owned by a package

We have now enabled a build time check that all directories are owned by a package and
this hit 49
s, most of them are fixed by now but packagers should fix the remaining

Other interesting bits

openSUSE 11.4 Milestone 3

Coolo announced that milestone 3 is
 due to some kernel bugs which the testing team encountered with their
daily testing scripts.  On 2011-07-18 the 3.0 RC7 kernel was checked in and should fix

openSUSE Conference

The call for papers is continuing to run, please submit session proposals at the conference site. Also, registration is open now.

After a couple of months of hard work we are now happy to introduce the next version
of SUSE Studio for onsite
installation. It comes in two editions, the Standard Edition, including everything you need
to create, share, maintain, and configure your software and virtual appliances, and the
Advanced Edition, which additionally supports workloads for System z, the big iron.

Team Reports

Header PictureBoosters Team


Members 1st

This time around the Boosters took on a milestone for the benefit of the Membership
Officials team. To explain who they are and what they do we have to look a bit further
into the openSUSE Project. Because of its history and relatively young age the project is
trying very hard to avoid hierarchies, policies and rules. It emphasizes the creative, a
bit chaotic, side of the FOSS ways for openSUSE to get things done, quickly. Everyone that
is participating is equal, everyone that is participating is following the same Guiding Principles. The
only formal structure is a a group of “Primus inter
, that is elected to provide guidance according to the
principles: The Board.

But how do you identify who is participating? How do you get affiliated with the
project? Who is a member? The Board came up with this
definition: Everyone who contributescontinued and
to the project. As you can imagine there are a million and one
ways to contribute to a huge project like ours, so judging if someones contributions
arecontinued and substantial can only be done on a case
by case basis. The Membership Officials are tasked by the Board to do this evaluation.

The process to become a member is dead easy. You tell the Membership Officials that
you want to be a Member and what you have done so far. They will then evaluate your
contributions and vote on your request. Once your request gets more then four positive
votes, you’re a Member. If you get four negative votes you get rejected. (…)

After some discussion in #opensuse-kde, darix has created the KDE:Apps namespace for KDE apps maintained
by their upstream, so that they can serve fresh packages for all distributions supported
by the Build Service (which includes

Top voted Features

Network installation could be improved by running package download and package
installation in parallel.



I wanted to open a fate feature about this when I first heard of plymouth, but
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?



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).



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.)



We need a feedback about packages that are preferred by users and actively used. Debian already has a tool named Popularity contest (popcon)

* reusing popcon will give us results that are directly comparable with Debian and Ubuntu

* packagers team can take care of the package

* we need a configuration dialog in YaST that is visible enough

* we need a server infrastructure on opensuse.org. (There are certain privacy issues, see Debian FAQ for details)


Recently requested features

Features newly requested last week. Please vote and/or comment if you get interested.


My suggestion is to enable multiversion kernel & preserve running kernel for
safer kernel updates, to reduce support problems when new kernels won’t boot. This is
now possible for 12.1 by 1 line change to zypp.conf.Since Online Update was first
introduced (SuSE 7.1?) it replaced the running kernel by default, which can lead to
problems booting. For a while multiversion kernel has been supported by libzypp (1 line
edit in zypp.conf). The drawback with multiversion was manual deletion required of
unwanted kernel packages (see http://lists.opensuse.org/opensuse-kernel/2011-07/msg00056.html ). Now in
Factory 12.1 M3 Michel Marek has included & announced – kernel package retention
options (see
http://lizards.opensuse.org/2011/07/14/improved-kernel-package-retention-in-12-1/ ).The
default is sane, to preserve the Lastest & Running Kernels. So lets use it and make
12.1 kernel updates safer for all, and by default do the right thing!



I’d like to have a simple way to have the ssh-agent load a number of keys
automatically when I log in to the system. The simplest way in my opinion would be a
directory, say ~/.ssh/ssh-add/, where the user can copy all the keys he wants to

Currently ssh-agent is already started when the user logs in using X11 by
/etc/X11/xdm/sys.xsession. /etc/X11/xinit/xinitrc which runs a bit later also executes
scripts in /etc/X11/xinit/xinitrc.d/. To me this seems the perfect place to add a small
script containing the following

#!/bin/bash if test -S
“$SSH_AUTH_SOCK” -a \ -x
“$SSH_ASKPASS” -a \ -d ~/.ssh/ssh-add;
then ssh-add ~/.ssh/ssh-add/* <
/dev/null fi

In fact, I use this script for a few years now. And I am sick of adding it to
/etc/X11/xinit/xinitrc.d/ after each distribution update.



openSUSE Linux 12.1/LXDE: Add support for the XZ Utils in Xarchiver .



If I need to do a bisection to find a kernel fault, the number of kernels in the
GRUB list gets very large.

The existing code handles the edit of /boot/grub/menu.lst; however, the kernels and
modules that correspond to a deleted entry are orphaned. A manual cleanup of /boot and
/lib/modules is tedious. An optional delete of the kernel files and modules would
eliminate the tedium.

Header PictureTesting Team


The Testing Core Team held an IRC meeting at 17:00 UTC, July 18 on Channel
#opensuse-testing on the Freenode IRC Network. irc://irc.freenode.net/opensuse-testing.

Our first agenda item was for discussion of our experiences with 12.1 MS3. As this
release was not available at that time, our discussion was limited.

Our second agenda item concerned our request to rename MS6 to Beta in hopes of
increasing the number of testers in the critical late stages of testing. As reported last
week, Stephan Kulow, the Release Manager, has agreed to make the name change although he
doubts that it will make much difference. He also asked how we will measure the effect of
this change.

We then discussed what metrics we might use to test the effectiveness of the name
change. Thus far, only the number of downloads and the number of bug reports have been
proposed. If you have any other suggestions, please send them to me. An interesting look
at the number of bugs reported against release can be seen at http://tinyurl.com/3mbrine
for all versions since 11.2. The decrease in bugs against the Final makes it look as if we
are doing something right. Of course, all statistics are lies!

Our final item of discussion was planning our next Open Bugs Day, which will be held
on August 21, 2011 from 0:00 to 23:59 UTC. This date is 10 days after the scheduled
release of 12.1 MS4. The emphasis will be on testing whether bugs reported for 11.4 are
still in 12.1. They will be fixed if possible, or updated to reflect the fact that they
still exist. All individuals interested in making 12.1 be an exceptionally good release
are welcome. As we get closer to the date, more specific instructions will be posted. As
usual, we will have special on-line tools to help you select a bug for investigation.

Our next IRC meeting will be at 17:00 UTC, July 25 on Channel #opensuse-testing on the
Freenode IRC Network. irc://irc.freenode.net/opensuse-testing. We will discuss our
experiences with MS3, now that it has been released.

squidview is one of the software, I’ve always build and installed on each squid proxy
server I build for me or customers. It’s small, stable, and usefull. So it was a clear
real nice candidate to be use to improve my obs and packager skiil.

I would like to thanks T1loc, yaloki, mrdocs, coolo, alin, and all others great
packagers around, for helping and teaching me during the process.


Squidview is an interactive console program which monitors and displays squid logs in
a nice fashion, and may then go deeper with searching and reporting functions.

(If you don’t know what squid is or does this program is probably not for you.)

To use squidview you must at least have read access to squid’s access.log file. You
may need to see your administrator for this. Squidview uses this text log file for all
operations. It does not generate its own database for tasks.

Header PictureKernel Review


Thomas Gleixner has released the first test version of a real-time (RT) Linux kernel based
on a current release candidate of Linux kernel version 3.0; having been slightly delayed, version 3.0 is due to be released any day now. With
version 3.0-rc7-rt0, the developers have taken the biggest step towards a modern basis for
the RT kernel, a kernel
that is chiefly maintained by Gleixner and several other developers – the current stable
kernel with real-time capabilities is still based on the Linux 2.6.33 series, which Greg
Kroah-Hartman has continued to maintain specifically for the RT developers. (…)



So there it is. Gone are the 2.6.<bignum> days, and 3.0 is out.

This obviously also opens the merge window for the next kernel, whichwill be 3.1. The
stable team will take the third digit, so 3.0.1 willbe the first stable release based on

As already mentioned several times, there are no special landmarkfeatures or
incompatibilities related to the version number change,it’s simply a way to drop an
inconvenient numbering system in honor oftwenty years of Linux. In fact, the 3.0 merge window
was calmer thanmost, and apart from some excitement from RCU I’d have called itreally smooth.
Which is not to say that there may not be bugs, but ifanything, there are hopefully fewer than
usual, rather than the normal”.0″ problems. (…)



The transition to the Linux kernel’s ‘third decade’ sees numerous
changes to the Btrfs filesystem. The kernel now includes all the major components needed to
host guest systems under Xen and includes many new and revised drivers.

Linus Torvalds and his collaborators have taken just two months to complete the latest kernel.
The most notable change, however, is cosmetic rather than technical – the transition from
version 2.6.39 to 3.0. This not been taken as a cue to insert major changes, however, and the
new kernel is in fact a perfectly normal version increment, following the pattern set for the
2.6 series.

New features in Linux 3.0 include the addition of a storage backend for Xen, which means
that the kernel now contains all the major components required to run as Dom0 – the merger of
Xen support appeared tantalisingly close six years ago, but it has taken until now for it to
actually happen. There have also been a number of changes to the Btrfs filesystem and to
graphics drivers. Kernel developers have as ever also added several new drivers and have
improved many existing drivers. (…)



Why do we always find the subtle bugs just before a release?

Looks like I won’t be releasing 3.0 today, just because Hugh found this incredibly subtle
pathname lookup bug. We have a patch, we understand the problem, and it looks
ObviouslyCorrect(tm), but I don’t think I want to release 3.0 just a couple of hours after
applying it.

Of course, the bug is so hard to see that Hugh needs weeks to reproduce it even with his
stress test, so we could just ignore it and backport the fix later. But I really hate making
releases with known issues even if it’s almost certainly a “nobody will ever hit this in
practice” issue

.Oh well.



As everybody knows by now, not only did I do an -rc7 last week insteadof releasing 3.0
(due to some worries about the RCU code), but I endedup also not doing the 3.0 on Monday
because of a pathname lookup bugand then some _more_ RCU issues.

Anyway, those should all be resolved and the fixes merged now, and I’mnot really all that
nervous about the pathname lookup issue – I thinkthat got nailed, and the patch for that was
literally just moving asingle line (and adding a comment).

The RCU issues worries me a bit, but everything says it’s all good,and the biggest issues
were with the new RCU_BOOST feature that reallyneither defaults to on, nor is suggested right
now. So I think we’reok, and I’m planning on doing 3.0 tomorrow. (…)

Are you still taking screenshots? That is sooo last decade. Today if you want to
showcase your application, your gaming skills, or even your astonishing new desktop
wallpaper collection, you need a screen recorder (or screencasting tool) to capture
full-motion video and audio of your desktop. You’ll find several solid options, but which
one works best for you depends a lot on the type of content you need to capture, and what
you intend to do with it.For starters, the output produced by the tool varies considerably.
Some alternatives give you a wide choice of video and audio codecs, others just one. But if
that one (say, Flash) is the one you need, producing it directly is much quicker than having
to save an intermediary file and crank it through a video editor. It also may be important
to select just a portion of the screen rather than your whole display, or to choose a
specific frame-rate (high for games, low for bandwidth-saving demos). Finally, there are
always special features that vary between utilities, such as whether or not they can capture
OpenGL content or be started remotely by script. (…)

For Commandline/Script Newbies


Part of my daily routine envolves accessing and managing a considered amount of remote
servers through the SSH protocol. I use screen a lot to ease the job by having a couple of
windows opened on each server, so avoiding multiple connections to the same server. By using
screen not only helps me grouping server windows altogether in one console window/tab but
also is a time saver in those days when network connection is not in its glory days allowing
me to reattach it and carrying on being productive (*sighs*). (…)



Although some file archivers offer us the option of split the files, this can be easily
accomplished with two commands: split and cat. (…)



RPM is a package management system widely used in various GNU/Linux distributions such
as: openSUSE, RedHat, CentOS and Fedora. All this distributions provides various package
management tools build around librpm (This library allows programs to make use of a rpm
database or rpm packages without using the rpm command ) or making direct use of
the rpm command. Examples of this includes: zypper – openSUSE package management tool andyum
– Fedora and Red Hat package management tool. This tools provides easy to use functionality
for installing, removing, searching, repository management etc, but they lack some
functionality provided by the rpm command such as listing the contents of a package, finding
what package provides some file etc.

This article will show you how you can use the rpm command to preform various package
management task , such as installing, removing, querying the rpm database, etc…


For Developers and Programmers


Whilst debugging a widget layout problem a few days ago, I was looking around for a tool
to view the structure of a Qt application without having to recompile it, or in other words,
Firebug / Web Inspector for Qt widgets.  I found the KSpy tool in the KDE repositories which is in
need of some love and there are a variety of tools to aid in runtime debugging and
modification of QML but not much in the way of tools for QWidget-based interfaces.  Please
let me know in the comments if I missed any.

I have put together a simple tool called Qt Inspector.



Man     Shut up! (It goes quiet next door) That’s better.He walks to a side wall and
hangs his club on a hook beneath big old-fashioned art-nouveau sign clearly labelled `The
Burlington Wall-banger’. He goes across to bed and gets in. In the bed are a party of four
Japanese businessmen in suits with lapel badges, two lady American tourists with rain hats
and cameras, three other moustached English gentlemen in pyjamas, four Tour De France
riders, three Swedish businessmen, and Winston Churchill.

So far we have been dealing with a command line interface for working with our Python
programs.  While command lines are good for a lot of things, they’re usually pretty bad for
interfacing with a general user of the program who doesn’t know how the various pieces
work.  What we are going to look at now is a different way of presenting the program to a
user (and probably a way that you are more familiar with) – GUIs.   GUI stands for
“Graphical User Interface”. (…)



Vim isn’t just a great
editor; it’s also a hugely flexible, configurable, and extendable application. You can even
set up Vim as an integrated development environment (IDE), giving you all the advantages of
a dedicated text editor together with the ability to check syntax, jump between tags,
autocomplete, and do all the other useful things you get from a modern IDE. These Vim tips
and tricks will get you editing like a pro. (…)



In this tutorial, we’ll be building a quick shortlink web app with Ruby, the Sinatra web framework, and theRedis database. By the conclusion of this tutorial, you’ll
end up with a dead simple, high performance shortlink webapp that’s super easy to scale.


For System Administrators


Tired of automated attacks on your systems? Want to beef up security a bit by denying
would-be attackers a third or fourth chance? Then you need Fail2ban. Fail2ban watches logs and then bans IP
addresses, based on too many password failures, by updating the firewall rules. Specific
rules can be defined by the user and multiple log files can be monitored. This weekend,
let’s get started on improving security with Fail2ban. (…)

… is a point in time where I think it makes sense to show
off a few of the things we are working on. While we will
introduce deep changes to the database this time, and are working on a way to establish
integrated version control for all components of SMB Traffic Analyzer, we
will also have some features that simply rock for end users.

We are pleased to announce that the Desktop Summit 2011 in Berlin will be supported by
Intel as the Platinum sponsor. The event organizers also welcome Collabora and SUSE as Gold
partners, and are delighted with the community spirit of these generous corporate partners.
Mirko Boehm, lead organizer of the Desktop Summit, said: “Their support is essential for the
Desktop Summit’s efforts to bring together Free Software developers from all around the
world to work in a collaborative spirit on the next generation desktop technology.”




I have good news this week. First, I’m still here because I passed the mid-term
evaluation for Google Summer of Code. Thanks for passing me Robin. Second, I was successful
in completing my goal last week and now have everything setup so others can start
experimenting with sharing files.

Besides general bug fixing this past week I’ve also refactored OC_SHARE, which is the
class that handles the database records of all shared files in ownCloud. It started to get a
little messy and I was unhappy with the quality of code so I rewrote many of the functions
and moved some of the error handling into OC_FILESTORAGE_SHARED where it should belong. I
also commented all of the functions so other developers can use OC_SHARE in their own apps
and understand what it is doing. I’ve also added two hooks to OC_SHARE: post_delete and
post_rename. These are triggered by OC_FILESYSTEM when files are deleted, renamed, or moved.
The database gets updated when these actions occur in order to avoid any missing shared

The backend for sharing is pretty much complete so I can now focus on the user interface
for the rest of the summer. The only part that needs updating is the permissions system. I
was having a difficult time deciding on what to do with permissions and ended up going with
only read and write, without the ability to permanently delete files. I’ve changed my mind
now and will expand the options to more specific permissions that you can assign users. I
was worried before that this would make the user interface too complex, but I now believe I
can still achieve simplicity with the user experience. (…)



The newly independent SUSE Linux unit unveiled the first leg of its cloud platform
today: SUSE Studio Version 1.2.

The development platform, which has been on the market for two years, helps SUSE Linux
customers build, update and manage applications. Version 1.2 allows customers to better
build, update and manage applications across physical, virtual and cloud environments
including public clouds as well as x86 and System Z mainframe systems.

In a recent interview, SUSE’s new chief, a 20-year Attachmate and Novell vet, said he is
preparing to roll out a full-fledged cloud strategy for the No 2 Linux distribution, even as
his on-the-job training continues. Top Linux distributor Red Hat has unveiled a
comprehensive cloud strategy in recent months. (…)



Mono isn’t dead, and SUSE isn’t giving up on it entirely either. Attachmate’s SUSE Linux
division today officially announced a deal with startup Xamarin for support and ongoing
development of Mono.

Xamarin is a company founded by former Novell employees including Nat Friedman and Mono
founder Miguel de Icaza. The pair founded the company afterAttachmate laid off an
undisclosed number of Mono developers in May, following their acquisition of Novell.

“What we’re announcing is that SUSE and Xamarin have entered into a partnering
agreement, which will make sure that we are able to effectively support customers using
Mono-based products,” Holger Dyroff VP Product Management at SUSE told InternetNews.com. “As
part of the partnership we are granting Xamarin a broad intellectual property license.”



Cats and dogs; apples and oranges; Linux and Microsoft. Two of these three things do not
go together. Would you believe that Microsoft—yes Microsoft—was the fifth largest
contributor to the soon to be released Linux 3.0
? Believe it.

In a Linux Weekly News story, currently only available to subscribers, an analysis of
Linux 3.0 contributors reveals that Microsoft was the fifth largest corporate contributer to
Linux 3.0. While only 15h overall, that still puts Microsoft behind only Red Hat, Intel,
Novell, and IBM in contributing new code to this version of Linux. (…)



The Linux Foundation is celebrating 20 years of Linux and as a part of the celebration,

If it wasn’t for Linux, a Windows Update crash would have forced me to format my drive
and reinstall everything. On Friday I got home from work, powered up my HP Pavilion DV6
6055ea laptop and watched as it promptly shut down to churn through Windows Update. It got
30 percent of the way through then the blue screen of death (BSOD) appeared.
