GUUG Frühjahrsfachgespräch 2014: CfP ends on May 31st!
Employee +0 Vote Up -0Vote Down

The German Unix User Group (GUUG) will hold their annual conference "Frühjahrsfachgespräch" on September 23-26 this year (I know, not really "Frühjahr" anymore, but this is how it is).

The Call for Presentations is still open until May 31st. Talks can be proposed in German and English, and there are slots for longer tutorials as well.

The range of possible topics is broad, so if you think you have anything interesting to share with a very passionate and technical audience of sysadmins and developers, here are some suggestions:

  • Operating Systems/Applications: architectures, privilege concepts, new developments, administration, mobile systems
  • Relevant new OS Kernel

Korean MySQL Power User Group
+1 Vote Up -0Vote Down

If you are a MySQL power user in Korea, its well worth joining the Korean MySQL Power User Group. This is a group led by senior DBAs at many Korean companies. From what I gather, there is experience there using MySQL, MariaDB, Percona Server and Galera Cluster (many on various 5.5, some on 5.6, and quite a few testing 10.0). No one is using WebScaleSQL (yet?). The discussion group is rather active, and I’ve got a profile there (I get questions translated for me).

This is just a natural evolution of the DBA Dinners that were held once every quarter. Organised by OSS Korea, and

Amazon EC2 Linux AMIs
+1 Vote Up -0Vote Down

If you use Amazon Elastic Compute Cloud (EC2), you are always given choices of AMIs (by default; there are plenty of other AMIs available for your base-os): Amazon Linux AMI, Red Hat Enterprise Linux, SUSE Enterprise Server and Ubuntu. In terms of cost, the Amazon Linux AMI is the cheapest, followed by SUSE then RHEL. 

I use EC2 a lot for testing, and recently had to pay a “RHEL tax” as I needed to run a RHEL environment. For most uses I’m sure you can be satisfied by the Amazon Linux AMI. The last numbers suggest Amazon Linux is #2 in terms of usage on EC2.

Anyway, recently Amazon Linux AMI came out with the 2014.03 release (see release

When I started writing this I wrote "Last week Opscode came" obviously now that is "A couple of months ago Opscode came with a bunch of announcements ... one of them being that they are also going to support the Open Source Chef .. rather than only their own platform.

I'd love to see more companies formally do this .. Over the past couple of years I've had numerous situations where organizations where happy to pay for support to an commercial backer of Open Source software... but they were not interested in , software updates, fancy dashboards , unneeded features.

Let alone being limited by some of the features of the Enterprise product (what do you mean there's no vlan support in Xen ? We've been using that for ages (anno 2008)

Using broken development frameworks , or why we don't use Zurmo
+0 Vote Up -0Vote Down

People often wonder why DBA's used to hate developers, and with DBA's also the System Engineers,
(note that I just expanded devops by adding dba's to the picture..)

So let me tell you a story ..

A couple of weeks ago one of our customers wanted to start experimenting with a new type of CRM. A gamified CRM.
Zurmo ...

So we set this thing up in a dev environment and started playing with it , while at first it looks nice ..
the application actually felt pretty slow.. however given that is a low resource development environment we looked no further.

Yet the next step is that we run into missing features, such as the fact that every contact you create by default is
set to private .. which really isn't productive for a CRM system where you want to be able to follow up on different
customer and share

MariaDB in Red Hat Software Collections
+1 Vote Up -0Vote Down

Towards the end of last year, I was asked to investigate the Red Hat Software Collections by someone that popped by one of my talks. SkySQL has been working heavily with Red Hat, and with Fedora 19 shipping MariaDB as a default, it seems like MariaDB is getting even more distribution. The Red Hat Software Collections 1.0 Beta is now available for users of Red Hat Enterprise Linux 6.

From a database standpoint, users now get MariaDB 5.5. I encourage all to try it, as it is an in-situ upgrade. It is described as:

MariaDB version 5.5, which introduces an easy-to-adopt

    Those who are familiar with me know I've a dream.

    5 years ago I decided to leave a systems integrator where I was doing great. Why? I wanted to be in a company with the same growth prospects that Oracle had in the 80s. I dreamed to be in the Oracle of 30 years ago and, as time travel wasn't affordable, I decided to join MySQL AB to help expand the business in Europe, the Middle East and Africa.
    A few years later my dream came true, but in a slightly different sense. Sun acquired MySQL and was later swallowed by

    Open Source Certification , Friend or Foe
    +0 Vote Up -1Vote Down

    With 2 of the bigger Open Source projects I care about talking about certifications programs questions pop up again ...

    Should we certify ourselves ?

    So let me tell you about my experiences in getting Open Source related Certifications ..

    Over a decade ago, (2001) when RedHat was still Redhat and not yet Fedora the company I was working for was about to partner with RedHat and needed to get a number of people certified for that.

    So I took the challenge, I bored myselve to death during a 4 day RedHat fast track training and set out to do the exam the next day. Obviosly I scored pretty well given my yearlong experience in the subject. Back then I was told that I scored the one but European Record on the exam which was actually held by another collegue (hey Ico) , our CTO however was not amused when I told that I could have scored better but I

    Read the original article at Oracle to MySQL – prepare to bushwhack through the open source jungle

    I was recently approached by a healthcare company for advice on suitable database solutions capable of executing its new initiative. The company was primarily an Oracle shop so naturally, they began by shopping for possible Oracle solutions.

    The CTO relayed his conversation with the Oracle sales rep, who at first recommended an Oracle solution that, expensive as it may have been, ultimately aligned with the company’s existing technology and experience. Unfortunately this didn’t match their budget and so predictably, the Oracle sales rep whipped out a MySQL-based solution as an

    Open APIs are the new open source
    +1 Vote Up -0Vote Down

    We’ve seen the rise of open source software in the enterprise and also beyond the IT industry, but the real keys to openness and its advantages in today’s technology world — where efficient use of cloud computing and supporting services are paramount — exist in open application programming interfaces, or APIs.

    Open source software continues to be a critical part of software development, systems administration, IT operations and more, but much of the action in leveraging modern cloud computing and services-based infrastructures centers on APIs. Open APIs are the new open source.

    You might have noticed that this blog changed name and URL. Instead of having one single blog for everything, I decided to split my blogging activities in two separate blogs.

    If you're interested in MySQL, Oracle, Databases, Business Intelligence, Open Source, Cloud, etc. this is the place to be. Blog's new name is Data & Co.
    A big "Thank you!" to David Stokes who moved all the planet.mysql.com references to the old blog to this new one.

    2012 to be year of Linux domination
    +0 Vote Up -1Vote Down

    Previously, I’ve called out years for non-desktop Linux in 2008, Linux in both the low and high-ends of the market in 2009, ‘hidden’ Linux in 2010 and last year, cloud computing in 2011. For 2012, I see continued growth, prevalence, innovation and impact from Linux, thus leading to a 2012 that is dominated by Linux.

    2011, A great year for MySQL in review...
    +11 Vote Up -0Vote Down
    I see so many posts on what happened to company X, product Y and dream Z that I couldn't resist the temptation to summarize this great year for MySQL. At the end of 2010, Oracle did an announcement we were all waiting for: MySQL 5.5 is GA! Another year has passed since then and it's time to reflect on what has been done.

    I know this is a long post. I tried to rewrite it at least 10 times to make it shorter, but I couldn't condense the list. Hence, I wrote a summary in the beginning for those who don't want to read it all.

    I believe that 2011 was an exceptional year for MySQL and I really enjoy being part of this team. I wish all of us a lot of success and fun in the years to come!

    The future of commercial open source business strategies
    +0 Vote Up -0Vote Down

    The reason we are confident that the comparative decline in the use of the GNU GPL family of licenses and the increasing significance of complementary vendors in relation to funding for open source software-related vendors will continue is due to the analysis of our database of more than 400 open source software-related vendors, past and present.

    We previously used the database to analyze the engagement of vendors with open source projects for our Control and Community report, plotting the strategies used by the vendors against the year in which they first began to engage with open

    VC funding for OSS hits new high. Or does it?
    +0 Vote Up -0Vote Down

    One of the favourite blog topics on CAOS Theory blog over the years has been our quarterly and annual updates on venture capital funding for open source-related businesses, based on our database of over 600 funding deals since January 1997 involving nearly 250 companies, and over $4.8bn.

    There are still a few days left for funding deals to be announced in 2011 but it is already clear that 2011 will be a record year. $672.8m has been invested in open source-related vendors in 2011, according to our preliminary figures, an increase of over 48% on 2010, and the highest total amount invested in any year, beating the previous best of $623.6m, raised in 2006.

    WebOS and the open alternative live another day
    +0 Vote Up -0Vote Down

    There has been no shortage of reaction to HP’s move to make the Linux-based WebOS open source software. Below, I offer some of my thoughts on the meaning for the different players affected.

    *What’s it mean for WebOS?
    Moving WebOS to open source was best option for HP. It retains some value in the software depending on its involvement. It is also the best fate for the code, rather then being sold or simmered to its IP and patent value or even used as another weapon in the ongoing mobile software patent wars. Still, the move comes amid huge developer and consumer uncertainty for WebOS. Nevertheless, at least WebOS was already in the market with a compelling products, the Palm the Pre, in the modern smartphone market. WebOS will hopefully have a faster path to open source than Symbian since the former is based on Linux. I still think the greatest opportunity for

    05.12. Doctrine 2
    +0 Vote Up -0Vote Down

    Object-relational mapping (ORM) frameworks have been around for several years now and for some people, ORM is already outdated by now. As we have seen with other technologies and concepts before, PHP is not exactly what we call an early adopter among the programming languages. Thus it took some time for ORM to grow up in the PHP context.

    There have been some frameworks before Doctrine 2 that implement ORM (remember e.g. Propel) specific tasks but most of them lack the required maturity to be used in large projects. With Doctrine 2, PHP takes a huge step into the right direction – Doctrine 2 is fast, extensible and easy to use.

    This article will take you on a tour through the main concepts of Doctrine 2 in the first part and then explain how to use it in

    Got open source cloud storage? Red Hat buys Gluster
    +0 Vote Up -0Vote Down

    Red Hat’s $136m acquisition of open source storage vendor Gluster marks Red Hat’s biggest buy since JBoss and starts the fourth quarter with a very intersting deal. The acquisition is definitely good for Red Hat since it bolsters its Cloud Forms IaaS and OpenShift PaaS technology and strategy with storage, which is often the starting point for enterprise and service provider cloud computing deployments. The acquisition also gives Red Hat another weapon in its fight against VMware, Microsoft and others, including OpenStack, of which Gluster is a member (more on that further down). The deal is also good for Gluster given the sizeable price Red Hat is paying for the provider of open source, software-based, scale-out storage for unstructured data and also as validation of both open source and software in
