If you haven’t worked with MySQL’s NDB Cluster storage engine yet, now is the time to take a peek. There is a sandbox available from serveral nines, which can be installed fairly quickly. This new article over at DatabaseJournal, MySQL Clustering In A Sandbox will have you up and running in no time.

Background
For several years, MySQL User Groups have been organizing their meetings with Meetup.com, a service that simplifies event management. However, MySQL User group organizers received a surprise message from Meetup.com a few days ago.
We were all taken by surprise by Meetup's sudden announcement and allegation that MySQL "did not want to sponsor" the users groups, because there is a valid agreement between MySQL and meetup.com. The agreement is still in effect, ending on June 10, 2009.
Apparently, there was some miscommunication inside Meetup.com, because the group organizers received a message stating that they should now pay for meetup services, which they used to get for free, thanks to MySQL sponsorship.
It took us a few days to track the origin of the misunderstanding, and when we …

From this Tuesday 12 May until Sunday 17 May I’m going to be in Darwin (Northern Territory, Australia), teaching custom MySQL training days for a medical research institute. DarLUG has been extinct for a while, but perhaps there are some local Linux/OSS people reading this? Please do drop me a line if you’d like to catch up while I’m there! I’ve only flown through Darwin before, never visited/stayed… and I love the tropics (I lived in Cairns for a while) so this shall be a joyous few days! Oh the tough things we have to do in business. I’m also doing a day trip to Litchfield… Kakadu will have to wait until another time (perhaps with Phoebe) as I’m told it’s best visited over multiple …

The first cut of a Java EE implementation of Olio is now checked into the repository. The file docs/java_setup.html gives instructions on how to build and setup this implementation. The implementation uses JSP, servlets, JPA for persistence, yahoo and Jmaki widgets for AJAX etc. The web application is located in webapp/java/trunk and the load driver, database and file loaders etc. are in workload/java/trunk.
Check it out.

I don't work with the Oracle database very much anymore, and one
thing I miss is their server documentation. I still have my old
copy of the Oracle 7.3 SQL Language Reference, and sometimes I
reach for it when the SQL:2008 standard has fuddled my brain and
I want to be reassured that SQL can be simple, powerful and
trustworthy. The calming effect is partly due to the
authoritative tone, but the railroad diagrams describing the syntax of each command say
'Don't worry'.
For example, here is Oracle 10.2's CREATE TABLE:
Yes, railroad diagrams. You can easily get lost in …

I read Jeremy’s post last week on jobs that matter and was also reminded of Tim O’Reilly’s post about the same topic from earlier this year (which is a great read by the way). This got me thinking, and I realized it has been about one year since I made the commitment to myself to get more involved with open source. I had been a passive member for over ten years, but I decided it was time for a change. After looking at various GNU projects, the Linux kernel, MySQL, and a few others, I decided to focus on the MySQL community. After attending OSCON I was even more inspired with the announcement of Drizzle, along with learning about other projects such as …

On my last count, there are now 20+ Sun Contributor Agreement (SCA) signatories whose names appear on the master list and who are interested in contributing to MySQL. Only this week, three new members signed the SCA.
These 22+ signatories have all been added since mid-February when we launched the new, Sun-compliant SCA signing process. Before the end of 2009, if we proceed at this same rate, MySQL SCA signatories list should grow to about 70 to 90 contributors.
In the meantime, contributions from many of these contributors have already been accepted and integrated. (I had earlier pointed to Armin Schöffmann's contribution as a simple example of how all this works.)
Some people continue to …

If you live near London or in the South East, mark your
calendars! A new meetup event is coming this week.
We will meet @6pm this Wednesday at:
The Lamb
94 Lambs Conduit St
Bloombury
WC1N 3LZ London
From MySQL, there will be Andrew Morgan, Mark Baker and
myself.
As usual, there isn't a strict agenda, the main topic will
probably be the outcome of the recent conferences in Santa Clara,
the MySQL User Conference and the Percona Conference. We have
lots of tech stuff to cover - Mysql 5.4, MySQL Cluster 7, Drizzle
and Xtradb, just to mention few.
I hope to see you there!
-ivan
P.S. As you know, we cannot comment on the recent Oracle
acquisition, so you have these options:
A) don't ask and enjoy the evening
B) buy us few pints and expect non-sense from us :)
C) all of the above
