Linux performance tuning tips for MySQL

MySQL on Windows: A survival guide for Linux-based DBAs

Next week, on Nov. 6, I will be delivering a webinar about running MySQL on Windows, with a strong focus on Linux-based sysadmins and DBAs – and how not to go crazy in the process.

linux.conf.au 2012 roundup

I spent last week at linux.conf.au in Ballarat, Victoria (that’s the Victoria in Australia, not wherever else there may be one) which is only a pleasant two hour drive from my home town of Melbourne (Australia, not Florida). I sent an email internally to our experts detailing bits of the conference that may interest them […]

Bearing the responsibility for someone else’s success means I should advise something that is stable, reliable, easy to manage and has plenty of resources available online. It should also allow running MySQL without too […]
