Last week Solutions Linux / Open Source event was held in
Paris.
Kuassi MENSAH (Head of Product Management Database Technologies,
Oracle Corporation) presented the open source Oracle strategy.
Linux, MySQL, virtualization, GlassFish, Eclipse, dynamic
scripting languages ,... etc . It was well received by the
audience. Knowing that MySQL organization will be kept safe in
Oracle is perceived as a nice move.
Florian Haas(LINBIT) gave a tutorial on DRBD and did some demos
with NFS and video streaming. And of course he reminded people
that now since Linux 2.6.33, DRBD is officially integrated into
the Linux kernel source. DRBD making the push for mainline Linux kernel
is going to make HA easier.

I’m pleased to announce the first release of Kontrollcomm – “The Server Command Automation Interface” is a web-based application that automates remote command execution on linux and unix based servers. There are three main areas of the application: Hosts, Templates, and Commands. The use is very simple: all of your hosts are setup in the [...]
This is a small revision and will only be available through SVN. However, it is an important one to speak about as it solves a former issue when running the application on a screen smaller than 1024px wide. While most users may not have noticed this since they have larger monitors it has been noticed [...]
I’ve recently been migrating my wiki/documentation for Kontrollbase to Trac. For those that are not aware, Trac is a web-based documentation/wiki/Subversion tool that is used by countless number of software projects. Subversion, of course, is a software collaboration and code management repository that manages branches/tags/trunk files with revision control. It’s one of the most heavily used open-source code repositories available. Given that I use SVN (subversion) for all of my software applications and am now using Trac, the book “Managing Software Development with Trac and Subversion” by David J Murphy comes as a useful and great resource for integrating these two useful tools. …

Piper Jaffray has published a 300+ page study on the cloud computing industry based on a recent survey undertaken of 100 CIOs. Bottom line, cloud computing is expected to grow significantly over the next five years.
Survey respondents expect the mix of cloud computing to escalate strongly to 13.5% in five years. This equates to a five-year CAGR of 19.2%, or 23.9% when we also incorporate IDC’s forecast that total software budgets will grow 4.7% annually. In other words, software spending will grow gradually in the next five years, but the mix of spend allocated to cloud-based applications will likely surge rapidly. Another way to think about the data is that the Cloud Computing market is expected to grow five times as fast as the broader software market: 23.9% vs. 4.7%.
If anything, I think the prediction is conservative and the impact could be much larger in magnitude when mainstream …
[Read more]I've been working in a fully distributed work environment for almost 8 years now (I joined MySQL AB in April, 2002). Therefore I've been reading Toni Schneider's blog post about the "5 reasons why your company should be distributed" with great interest – he raised several points that I fully agree with and which I covered in my talks about "Working for a virtual company - how we do it at MySQL" at last year's next09 conference (slides, video) and at …

In my last blog post, I showed how we can get some raw
performance information from /proc into the MySQL database using
a LOAD DATA INFILE (LDI) command.
I've modified that LDI call slightly to set the `other` column to
equal the sum total of the CPU counters for those rows which
begin with 'cpu'.
original:
other = IF(@the_key like 'cpu%', NULL , @val1);
new:
other = IF(@the_key like 'cpu%', user + nice + system + idle +
iowait + irq + softirq + steal + guest, @val1);
Top provides a useful output that looks something like the
following:
