One of my old students and lab assistants stopped by to show his fiancée the BYU-Idaho campus. It was a long trip since he lives in Macao, China.
He kindly brought me a copy of my Oracle Database 11g and MySQL 5.6 Developer Handbook in simplified Chinese. He’s holding it in the photo.
That makes three books translated into Chinese, which made my day. It’ll be interesting to see if the new

Just went through all my PHP testing against a fresh instance of Oracle with Zend Server Community Edition 6, and found these warnings, guess that’s pretty clean for the Oracle part of the installation. I didn’t notice it before because generally I do most of my PHP development against a MySQL database. I should have been configuring the php.ini file routinely, as qualified in this PHP forum discussion.
Warning: oci_set_client_info(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your[Read more...]

[Read more...]MySQL Enterprise Backup (MEB) was born 3 years ago as a newly branded avatar of InnoDB Hot backup. Wanted to share what has gone on so far, how we at Oracle think about backup, the milestones that we have achieved and the road ahead. The idea for this blog came to me after looking at Mikael's latest blog. While Mikael talks about MySQL, I want to talk about MEB.
When we started with InnoDB Hot backup the first challenge was to have it adhere to the development, quality and release processes for MySQL. This meant creating a quality plan, getting it into the development trees of MySQL and ensuring that each piece of new code went through architecture and code review. Though the initial implementer and architect of Hot backup continues to work with the MEB team, there

People often write a blog post when they reach some nice anniversary since they joined MySQL community. Well, for those old enough it usually means when they joined MySQL AB as employee. For me this was January 2008. Because I didn't remember the month correctly, I haven't blogged anything then, but decided to save it for a better opportunity - now.
TL;DR Starting this week I will be working for 10gen, selling MongoDB to the Nordics. This blog post is really long - even then it doesn't contain the most interesting stories, I'm not sure if they can ever be published. Sorry for the length, but remember you don't need to read all at once. This is my last MySQL post so save some of it for cold winter days!
I wasn’t at the MySQL Conference this year but it was very nice to follow this event from Paris.
Of course I didn’t feel the general atmosphere by visiting booths or met fabulous people.

Twitter, RSS feeds (yes Google, I still use RSS), Planet MySQL and infiltrators were my best friends during this crazy week.
I would like to summarize the major announcements and events occurs during this tenth edition.

5 years ago I decided to leave a systems integrator where I was doing great. Why? I wanted to be in a company with the same growth prospects that Oracle had in the 80s.
