Learn how GlassFish and NetBeans helped Ginga community to build a TV Banking
application in Brazil. See a live demo of the product, it's
really exciting!
Why GlassFish ? - They love how NetBeans tooling completely hides
the complexity of what's happening underneath and the ease-of-use
with GlassFish.
Thanks Hugo Lavalle for the interview and good luck with your
product!

Introduction
MySQL Server (starting from v 5.0), as Oracle and SQL Servers, allows creating stored procedures and functions.
Stored procedures are a set of SQL commands that can be compiled and stored on the server. Thus instead of storing a frequently-used query, we can refer to a corresponding stored procedure. This provides better performance (as this query is analyzed only once) and reduction of traffic between client and server.
While developing business logic of procedures, we often use a great number of variables (e.g., temporary outputs) to store. To assign static values to a variable or values of other variables, SET operator is used. SET operator in stored procedures is an extended version of usual SET …
[Read more]I reported a bug about SHOW BINLOG EVENTS not working with relay logs a couple of years ago - Bug #28777.
It’s now been fixed in MySQL 5.4, by adding a new SHOW statement - SHOW RELAYLOG EVENTS.
The replication team are really hammering through things at the moment - Kudos!
this is source code for a tiny program I just wrote that traverses specified directories and removes them from file system cache.
There are few use cases for it. One is for all these people who benchmark stuff and want selective OS cache purges, another is for those who run high performance databases. Remember the O_DIRECT serialization everywhere? Well, XFS does direct I/O in parallel, unless there are cached pages (and they can happen because of any random outside-of-database activity, like ‘file’ command). Once you ‘uncache’ the files, XFS will be very much parallel again \o/ \o/
Reanimating the Sydney MySQL User Group!
What: Sydney MySQL User Group meetup #7 - The Reboot
When: July 16, 2009 5:30 PM (please don’t forget to RSVP yes/no/maybe)
Where: Sydney, CBD - join the meetup for exact location.
We are back! After 3 years of being silent, SMUG (can I call it so? I know there are conflicts with other acronyms) resurrects the meetings.
The logistic of the meetup is the following:
A new version of the DRBD User’s Guide is up at http://www.drbd.org/users-guide. As this version
has some major additions to the previous release, I’ve decided to
create a release
candidate this time, before declaring this an “official
reference” — everyone’s feedback is requested and highly
encouraged.
What’s new is Chapter 8, “Integrating DRBD with Pacemaker clusters“. It deals with the new drbd OCF resource agent we are about to release with 8.3.2, and how to use it in Pacemaker clusters using the CRM shell. It also has setup examples for MySQL, as does the legacy chapter on Heartbeat. Please grab the 8.3.2rc2 tarball if you are …

The call for papers for OSDC 2009 is open until 30 June 2009; yes that’s only a few more days. Submit your abstract and do a talk at this fab conference!
This is a grassroots style conference designed by developers for developers. It covers Perl, Python, Ruby/Rails, PHP, Java/Grails and Open Source operating systems as well as some business aspects. If you’d like to cover something else as well that is Open Source themed, please feel free.
The Call for Papers can be found at: http://2009.osdc.com.au/call-for-papers

When I joined MySQL back in June of 2005, one of the first “MySQL Truths” I learned and repeated often when discussing MySQL with others was “release early, release often.” If you’ve been using MySQL for any length of time, you know what that statement means – it meant that MySQL was: (1) dedicated to getting new features and enhancements into the hands of its community so the software’s quality could be validated; (2) eager to take early feedback on those features so the input could rapidly be incorporated back into the product allowing everyone to benefit; (3) committed to very frequent releases of the software so helpful new features and/or external contributions that were ready for action could quickly be put into play and not sit idle on the shelf. And if you’ve been around Open Source for a while now, you know this is the spirit in which most providers of Open Source software operate.
