I’m migrating my existing WordPress run blog site at blog.arabx.com.au to a my new site ronaldbradford.com (which is not yet publically available)

As part of this process I’ll be doing a number of upgrades/changes including:

1. Update blog software to 2.5.1 from 2.0.2 (I’d previously done a 2.0.2 upgrade to 2.3.2, but not deployed)
2. Migrate to new domain
3. Upgrade existing MySQL 5.1 version from 5.1.11 to 5.1.24
4. Migrate database to using MySQL 5.1.24, from 5.0.22 (my server runs 5.0 and 5.1 instances)
5. Split my blog into Professional & Personal

Upgrading
The upgrade is straightforward, backup database, download latest wordpress software. I run full revision to older versions via directories + symlinks so my installation is more …

There was a problem with MySQL 5.0.51a binaries for Windows and Mac OSX. They did not work out of the box. On Mac OS X, the installation succeeded, but the start panel did not work and needed a patch. On Windows Vista, the installation sometimes failed.
Both problems were fixed after Colin's heads up.
Thanks to Daniel Fischer, Kent Boortz, and Ignacio Galarza, who fixed the problem very quickly.
The new binaries (5.0.51b) are available from MySQL downloads page:

• Windows 32bit
• Windows 64bit
• …

Hakan Küçükyilmaz has just posted a new article  about the Falcon Engine.

There he explains that the Falcon Team at MySQL AB has added this week six new tests to the Falcon test suite and he reports (as usual) a time-trend chart of failed and passed Falcon tests.

I have calculated the ratio failed/passed tests and we can see that it is improving:

9%    |  (17:190)  |  207 tests in total  |  the last week
10%  |  (19:182)  |  201 tests in total  |  two weeks ago

Of course the ideal ratio is 0% i.e. 0 test failed.

In that post Hakan was wondering where and how Users use the Falcon Engine, what features they like/not like or want to see in it. Also he solicited Users for testing Falcon and reporting Bugs …

I recently came across this blog post with the catchy title of “DRBD and MySQL: Just Say No”. Now while I have absolutely no issue with people not liking DRBD or finding that it doesn’t fit their needs, I couldn’t help but notice that the post recycles some persistent myths about DRBD, which could use some correction.

I’ve tried to reply using a blog comment, but alas it seems I was moderated to /dev/null. Enter the “Write Post” button on my trusted WordPress dashboard.

So let’s look at the alleged “MySQL with DRBD Minuses” mentioned in said post I am referring to:

DRBD partition corruption means failover node would be unusable (disadvantage of shared storage) and failback could destroy …

Every year I meet a lot of new and old friends at the MySQL conference. To highlight their involvement in the MySQL community and at the conference I have decided to start a new series: "People I met at the MySQL conference."

I probably won't be able to cover everyone I met (sorry about that) but I intend to cover as many as possible. There will be no order in which I cover people. Also, there is no secret agenda and of course whatever I say is just my personal opinion. Just whenever I have a few thoughts ready about someone, they will pop out :)

I talked about Microformats in a post last year on web20expo. It appears that the technology is now going main stream. I attended a workshop on Web2.0 Best Practices at the Web20 Expo this week in which the speaker, Niall Kennedy expounded on th advantages of using microformats. He said he's seen a significant growth in traffic on his site since he started doing so since search engine results show direct links to pages on his site.
Yahoo is adding microformats to many of their properties. The yahoo event site already has them. This is …

The first Version after Workbench was released for GA is available now on our servers. We are constantly working on improving our application in terms of stability and handling.

Maybe you’re curious if you missed a version as the official GA release version was 5.0.19 - no, you didn’t. While preparing 5.0.20 for release, a problem was detected when running last checks on the finished packages. Unfortunately we had already uploaded the packages to our mirror-system. That’s the reason why 5.0.20 is listed as ‘internal’ in our release history (can be checked on About Releases page) and the actual published version available is 5.0.21.

Please download and update to the latest version.

Let us talk few more about disks. You might have read my previous post and Matt's Reply and it looks like there are few more things to clarify and explain.

Before I get to main topic of the article lets comment on IO vs Disk question. If you look at Disk Based databases all data accesses are treated as IOs - it can be "logical" if they are cached or "phyiscal" if they require actual IO done but in the general sense all data accesses are IOs. If you use this terminology when most of the problems would come down to IO - making queries to touch fewer rows (or row portions) or having these "touches" resolved as logical IO rather than physical. There is still locking ,networking etc to deal with but it is minor story.

This is not however as Most of the …
