Andrew and Matt will be delivering a free webinar this Thursday at 10 AM Pacific.

If you are currently deploying MySQL applications on Windows that have high performance and availability requirements, I would recommend checking out this webinar to learn more about what has been going on lately to make Windows a fully supported platform for MySQL Cluster in the near future.

They'll be covering fundamentals, like architecture, installation, configuration and administration. So, if you are new to MySQL Cluster and want to learn how to get started with the latest preview release, this webinar is definitely worth checking out!

A quick review of Save MySQL online petition stats shows that the results are still in line with the results I reported previously. Over 90 percent of petition signees would require Oracle to divest MySQL to a "suitable third party."

A Happy New Year to all of you! About a month ago we posted our initial Call for Papers for the MySQL Developer Room at FOSDEM 2010 in Brussels, Belgium. We already received several great submissions and we'd like to thank the speakers who contributed their suggestions so far. But we would like to get some more!

Therefore we decided to extend the deadline for a few more days: you can still submit your talk proposals until tomorrow (Wednesday, 6th)!

So if you think you have an interesting MySQL-related topic to talk about, we'd like to hear about it! Thanks.

There are now some interesting Storage Engines out there, beyond the usual MyISAM, InnoDB, NDB etc. The question is then, how do they perform? And as usual, I was a bit curious on the feasibility of these new guys on Windows?

I decided to try out MariaDB first, based on MySQL 5.1.39, and this also includes PBXT, which was convenient, now I got a chance to try, with one installation, InnoDB, MyISAM, Maria and PBXT. The MariaDB Windows download was no fun at all, though. This includes among many other things, the text setup (300Mb just that), pdb files for libraries and executables, embedded versions and debug and optimized libraries, adding up to a whopping 869 Mb on disk (but you have to exclude my current data which amounts to 94 Mb). Standard 5.1.39 is 134 Mb on disk, excluding data.

What is more annoying is that there is no installer, no MSI no nuthin', just a zip. Which is sort of fine for me, but goes to show that …

The Problem

I've had MySQL on my Windows 7 laptop for a bit (as part of wampserver), mostly for local offline WordPress development.

However, even though MySQL is relatively stable, I've been observing a vast quantity of intermittent MySQL errors, as reported by WordPress in the PHP error log (C:\wamp\logs\php_error.log). Here are some examples:

[05-Jan-2010 09:47:51] WordPress database error Error on delete of

I recently was asked the following from a Kontrollbase user via email. Since this question might be asked by others I’m posting my response so that the user community can have the answer available right here, right now.

Today I caught a tweet from Kara Swisher referencing some exclusive news she posted on Boomtown about VMware’s upcoming deal to buy Zimbra from Yahoo! This is would be VMware’s second acquisition of an open source ISV in under a year. In August 2009 VMware …

VMWare appears to be positioning itself to provide the virtualized or cloud-based alternative to Oracle, Microsoft and IBM. This is a very interesting approach, and it will be interesting to see it play out over time. With Oracle and IBM taking a more systems-centric approach, meaning they are both providing the storage, computing and software stacks in the form of a system, this leaves Oracle’s traditional hardware partners out in the cold (HP, Dell, EMC, Netapp, etc.) along with budding potential partner Cisco. VMWare may envision themselves providing the Linux-based alternative to Microsoft in this game of strategic positioning. VMWare’s strategic advantage is that their entire stack is virtualization- and cloud-friendly. That would make sense given Maritz's Microsoft experience.

This diagram compares the various stacks from VMWare's perspective (e.g. they are all on top of VMWare instead of their own respective virtualization …

Being an employee of MySQL (past and present), every time I see something related to dolphins it catches my eye - and I just came across this:

Scientists say dolphins should be treated as ‘non-human persons’

The treatment of dolphins has long been an issue for me, I utterly despise some of the things I have seen, and read about. MySQL’s dolphin - Sakila - has always been seen as a symbol of freedom. This is marred by reality, hopefully this will change:

“The researchers argue that their work shows it is morally unacceptable to keep such intelligent animals in amusement parks or to kill them for food or by accident when fishing. Some 300,000 whales, dolphins and porpoises die in this way each year.”

Some other things in the article also ring true for me, in other ways. …
