This year I was speaking at Collaborate 11 about actions one need to perform when find her SQL application behaves wrongly.

New thing which was not presented in my earlier notes is simple how-to of how to deal with replication errors. You can find this in second presentation.

Slides are here: part 1 and part 2.

I also created PDF diagram which can be print and used as visual aid for cases when you meet an error. You can download it here or at the Conference website here (see file for session 410).

Oracle announced on Friday that it is to discontinue its commercial interest in the OpenOffice.org project, prompting a barrage of criticism from the open source faithful with regards to its approach to the open source applications project, and community in general.

The company was accused of being community-hostile, for example, and comparisons were also made to Colonel Gadhafi, while a translation of the press release into “plain English” apparently shed new light on the announcement.

In truth though, the language …

It's now been 12 months since Oracle absorbed Sun. A lot has happened in that time, and the good news is that Sun's technology has a new lease on life. Reviewing my blog entries over the last 2 or 3 years, most of them were focussed on MySQL and T-series systems. Lots of good things are happening with both product lines.

As for me, I've been working on SPARC Supercluster. More on this topic later... ;-)

Every March we have a lot of bug reports and support issues about Daylight Saving Time changes.

General rule here is to remember 1 hour at March, 27 night will be missed in most of European countries: for example in Moscow after 01:59:59 next time will be 03:00:00. And yes, I am too late for America =)

MySQL handles such timestamps properly, therefore expect no such time and date will be inserted in STRICT mode and next valid date will be inserted for not existent time in forgiving mode. For Moscow '2011-03-27 03:00:00' will be inserted if you try to insert timestamps in '2011-03-27 02:00:01' - '2011-03-27 02:59:59' range.
