One of our senior MySQL DBAs, Mike Hamrick, wasn’t feeling well this week and so stayed home from the office. Instead of actually resting, produced this video about reading top output! I leave it to you all to watch and learn from our local tool tip pro.
And, feel better Mike!

Openworld 2010, despite the supposedly lagging economy, had record attendance again this year. No doubt this was the result of Oracle acquiring something like fourteen companies since last year, including Sun in 2009. The crowds were thick, divided about evenly between geeks in badly-fitting vendor t-shirts and slick sales-side hustlers with dress pants and shiny shoes. I landed somewhere in the middle of the two (badly-fitting dress shirt, comfortable jeans and loafers), proudly sporting a long dangling codpiece of ribbons from my attendee badge:

Oracle made a number of important announcements this year at OpenWorld, including a the Exalogic machine, and support for Amazon EC2, which I blogged

There are a lot of people here using prepaid phones as opposed to postpaid phones. This is because the requirements of getting a postpaid account is quite tough (you need bank documents, etc. before they give you an account).
Many people carry more than one phone (or have more than one SIM). Smartphones face an uphill battle – they cost too much and there is generally no operator subsidy because everyone prefers prepaid accounts. It makes economic sense to have more than one SIM,

I created the Bluegecko MySQL training AMI as a MySQL sandbox that folks could use to learn things about MySQL. I wanted the AMI to have MySQL 5.0, and a large collection of tools — for both tinkering and visualizing what is happening inside MySQL and on the system in general.
I chose to host the AMI on a small instance since they’re cheap to operate, which means you can fire up 3-4 of them to try out a replication scheme without feeling guilty. It runs CentOS 5.4 and MySQL 5.0.77 from the CentOS repository.
One of the goals I had for the training AMI was for it to be easy to visually inspect what is going on inside of MySQL and the system at large. To that end I’ve installed Cacti, a graphing and visualization tool, and equipped it with templates

This Thursday (October 1st, 14:00 UTC), Calvin Sun will give a session on InnoDB Internals: InnoDB File Formats and Source Code Structure. The InnoDB storage engine provides transactions, row-level locking, and automatic crash recovery. Its on-disk files play a pivotal role for those key features. This presentation describes how on-disk files are structured, how compressed tables are organized, and how long variable-length columns are stored. As we develop new features, it is inevitable for file format changes. We will explain how the new file format management works in the InnoDB Plugin.This talk also covers InnoDB source code

We'd like to fill the remaining session slots for MySQL University this year. Currently, there are 7 available slots in 2009, as can be seen here:
http://forge.mysql.com/wiki/MySQL_University#Upcoming_Sessions
Anyone who has something technical to say about MySQL qualifies as a speaker. MySQL University sessions take place on Thursday afternoons European time, and normally have between 20 and 30 attendees, but quite a lot of people listen to the recordings when the live session time isn't convenient for them. We're using Dimdim as our conferencing system, so the setup for speakers is very simple: Just

Admins in the U.S got a chance to talk shop at EDUCAUSE and the LISA ‘08 summit, but what about those in Europe? Don’t despair, because we’re co-hosting a mini-conference with MySQL, SchoolForge, RedHat, Sun, Op5, and Fusis at our UK headquarters in London on November 27th.

Good news Kettle fans!
Our community is bound to become a bit larger as a whole group of students (38) at the Katholieke Hogeschool Mechelen (Batchelor level) will receive a one day workshop with Pentaho Data Integration (Kettle). This workshop will take place in early November, most likely the 4th.
It’s interesting to see that during that day we’ll be able to go through most of the work involved in reading and staging the data, data cleansing and a few slowly changing dimensions with a fact table. On top of that we’ll explain how to use Pentaho Data Integration in that setting. When time permits we’ll show how to set up a metadata model on top of that data to create reports on it. On top of that the students will get an idea about what exactly

One day I will visit this amazing place, and spread the good word of open source with projects that are close to my heart: MySQL, OpenOffice.org, Fedora, and in due time, a lot more. This is a live-blog, from a most interesting talk, at JavaOne 2008. As I wrote on Twitter, “Brazil, simply impresses me. Their use of open source in government, makes me think that the rest of the world has a lot to learn from them”.
