Two great posts were written over the weekend on MySQL, and I'd encourage you to read both. The first is from Pierre @ Milking the GNU who has some ideas for how MySQL/Sun can make money with a 21st-century software business. The second is from Glyn Moody, wondering if ...

This past week I was out in the Bay Area for the MySQL Conference and Expo. I hit the pre-event parties and attended the conference's opening day. The first day featured a great set of opening keynotes from Marten Mickos, Jonathan Schwartz and Werner Vogel, CTO of Amazon.
Marten Mickos, tellin' like it is.
Jonathan Schwartz divulging Sun's "secret plot."
The main reason for my attendance at the Conference was to get a bunch of podcast interviews as well as to be interviewed by the press as Sun's "Linux Guy." I ended talking to the Register, Information Week and DevX as an interviewee.

Lustre is one of the most popular upcoming open source cluster file systems out there. When you want to run Xen’s from a SAN using Lustre you need to support both in the Linux kernel. Both XEN and Lustre are near mature products. This means there is support for it. But it’s quite difficult to find the right source and to combine it with the right kernel source of each. It took me a week of trial and erroring until I found a combination that worked. Since Google wasn’t much help I wrote this article so it might help you. This installation is Ubuntu Gutsy specific. You can start out with a basic Gutsy installation. Hardy is getting Lustre support, but at the time of this writing the package doesnt match the default kernel of Hardy.
First we apt-get some utilities and Xen packages
apt-get install quilt libc6-xen libxen3.1 …[Read more]

Once again I spent a week in the San Francisco Bay Area. This time around it was for LugRadio Live USA 2008 and the MySQL Conference & Expo 2008.
I flew in on April 12 (from FRA via LAX
to SJC) and arrived in the hotel, the Hyatt Regency
Santa Clara, in the afternoon.
The next morning I left the hotel around 7:00 in the morning for a genuine experience of what they call public transportation in the bay area. It took me three hours to travel the distance of …

*Disclosure: I am an advisor to TargetSource see: TargetSource Official Launch
1. How did you get started?
After 7 years effort on open source community and 3 years business practice on open source services in China, we think it is a right time for us to start up TargetSource. More and more companies always ask us to help them to solve problems when they use open source, sometime if you are just a individual, it is not a long term strategy for company to get support on open source software. That’s why we started TargetSouce, an open source service company which delivers to end customers by a global collaboration network with partners base on the open source software.
2. What is your product?
TargetSource strategy is not building a single open source component or product such as JBoss, hibernate, Spring or so. From our …

With assistance from Antony Curtis who spent some coding time
with me at the conf, and a number of helpful other individuals
(Monty, Sergei, Timour, Igor, patg, Stewart, Brian, Mark, Paul,
and others) who answered questions and looked things up, the
earlier backend demo can now be executed from a MySQL
5.1 server with the OQGRAPH Engine plugin loaded. In other words, the
basic glue has been completed, and the prototype works. Thanks
all!
This was later in the week, so at the BoF Tuesday night we still
had to make do with paper and the backend test tool, but Thursday
evening and Friday I was able to demonstrate the real thing,
including at the post-conf MySQL unconference at Google HQ. I was
happy to see good interest in the GRAPH engine, and also received
some very useful …
