MySQL Security Webinar: Follow-up Q&A

MySQL Security: Armoring Your Dolphin

My colleague and teammate Ernie Souhrada will be presenting a webinar on Wednesday, August 21, 2013 at 10 a.m. PDT titled “MySQL Security: Armoring Your Dolphin.” This is a popular topic with news breaking routinely that yet another Internet company has leaked private data of one form or another.

Percona response to recent MySQL security bugs

Recently there have been discussions on several vulnerabilities in MySQL and closely related projects such as MariaDB and Percona Server.

MySQL 5.7 key features

After that conversation, I thought it would be a good idea to compile list of important features of MySQL 5.7. The latest MySQL 5.7.6 release candidate (RC) is out and is packed with nice features. Here’s a list of […]

The value of MySQL Support

Years ago when I worked for the MySQL Support organization at the original MySQL AB, we spoke about MySQL Support as insurance and focused on a value proposition similar to that of car insurance. For your car to be fully covered, you must purchase car insurance before the incident happens – in fact most places […]
