The MySQL community impacting the Oracle community

I’m happy to announce that the MySQL community has been given the opportunity to speak at the upcoming Oracle Developer Tools User Group (ODTUG) Kaleidoscope conference in Washington DC. We will be releasing more details this week of the MySQL presentations and topics and we are finalizing details of possible options to include the local MySQL community during the event.

The MySQL documentation is not always right

Let me premise this post with the statement I think the MySQL documentation is an excellent and highly accurate resource. I think the MySQL docs team do a great job, however like software and people, documentation is not perfect.

The Drizzle Census

We hear of 50,000 windows downloads per day but this is misleading because MySQL is basically bundled with Linux by default or installed from various repositories.

Installing Ubuntu Desktop 10.04 with LVM

With a new quad core desktop with 8GB RAM & 1TB HDD I wanted to install the Ubuntu desktop version using LVM. This is not possible with the “Desktop CD”. You need to use the “alternative CD” which will easily allow you to configure LVM via a text/cursors installation and also give you a deskop GNOME environment.
