At LISA 2008, I gave a presentation entitled “How to Stop Hating MySQL: Fixing Common Mistakes and Myths”. The video and presentation slides are available here.
Recently we quickly and efficiently resolved a major performance issue with one of our clients related to a central database that was intermittently freezing because of high CPU usage. In this blog, I will discuss this performance issue and its solution.
Have you ever used Perfmon to collect performance statistics about a particular Windows Server? Do you hate manually picking the counters out of the list? Do you trace basically the same counters every time? If you answered “yes” to any of these questions, here’s a tip that can save you some time.
Happy birthday to Giuseppe Maxia, a wonderful community organizer for MySQL, and happy birthday to Leslie Hawthorn, Google’s geek herder. Thank you for making life better for open source volunteers like me!
For those of you who have been under a rock for the last several years, there is a buzz-phrase floating around—cloud computing. If you haven’t been paying attention, it is time to wake up. While I could spend an entire blog post—if not several—on a definition of cloud computing, I will be talking only about cloud computing in the sense of companies moving servers from their building or network operations center to running virtual servers in this computing cloud.
I have put up a poll on my personal blog, Diamond Notes asking whether you prefer Ubuntu or Debian as an operating system for MySQL server.
OpenSQL Camp is a free unconference happening Friday, Nov. 14th through Sunday, Nov. 16th in Charlottesville, Virginia, USA. More details can be found at http://www.opensqlcamp.org.
This has been discussed before by my colleague Paul Moen in his article on Oracle standby recovery rate monitoring, but I recently made a discovery that makes it easier to generate both statistics on log apply performance, and more useful stats too. First, let me say that this discovery is based on my observations and has not been verified with Oracle Support nor by any insider. If you know one who can confirm this, please ask him or her.
I took part in a webinar on cloud computing today, including some of the top names in cloud computing services. As Pythian has some MySQL clients using cloud computing, I was interested by the many levels of what cloud computing means, including such categorizations as Facebook apps being a part of the cloud. I think many of us consider cloud computing to mean “virtual infrastructure as a service” and overlook some pretty robust cloud computing that’s already out there, such as “application components as a service” and “software [platform] as a service”. Following are my notes..
I’ve been volunteering since I was 14, and I did not stuff and seal thousands of envelopes thinking about a return on my investment. Sure, I may have been enticed by something (free pizza) but in the end, where people donate their time and money is a very personal thing. They donate time and money to causes they believe in.
