KEY ACCOMPLISHMENTS LAST WEEK

• Fixed some left over glitches in Skoll Client related to the Bazaar switch, mostly to deal with Java Runtime exec.
• Analyzed MySQL runtime data, but did not find clear differences between different configurations of MySQL. The analysis might need more granular runtime data, see next item.
• Modified Skoll Client to collect runtime information per MySQL test. Right now, Skoll Client runs mysql-test-run script (which executes all tests) then collects gcov runtime information for all tests.

KEY TASKS THAT STALLED LAST WEEK

• None

KEY CONCERNS

• None

TASKS IN THE UPCOMING WEEK

• Finish per test runtime information collection modifications.

While we were mostly excited to become part of Sun, there was at least one drawback too. MySQL had a worldwide policy of "Scandinavian style" 5 week vacations per year (4 Summer, 1 Winter week). Sun doesn't have such a worldwide policy, so most of us lost some vacation days there. But there is one group of employees that still enjoy this benefit... those of us that actually live in Scandinavia!

Those 4 weeks are however now gone for my part :-( So I thought I'll make a soft start to working by a) yesterday doing almost nothing and b) today blogging. A long long time ago before I left for my vacation Mark Callaghan requested more blog posts about MySQL Cluster, so I thought why not start with one right now. As previously noted there are many good MySQL Cluster bloggers out there, but admittedly some of their blog postings can be very …

Infoworld published the 2008 Bossies, Best Of Open Source Software. There are 8 categories and none of them are database:

• Collaboration

It says:

So Cuil had lots of visibility because of their "data corruption" , showing "wrong" images to people.

However it seems like they still haven't cleaned up their mess.

Somehow they manage to place Geert Vanderkelen's picture in the search results for me.
Not the other way around however.

Well.. at least it isn't what they used to show :)

So Geert , if someone ever runs up to you and says "Hi Kris" , you know where they got the picture from :)

While the debate on 'what is open source' continues, the larger question of how to grow open source vendor revenue across the software market is still largely ignored READ MORE

This is the inaugural post in the weekly series "Last Week in Drizzle" where I summarize the efforts of various folks in the Drizzle community over the past week. There is a ton of enthusiasm and excitement around what is going on in Drizzle as evidenced by an explosion in the number of people tracking the mailing list and participating in coding, refactoring, testing, documentation, and general community efforts. As of this writing, 148 people are following the mailing list; this in only the second week since Brian announced Drizzle at OSCON. Pretty awesome. What is also cool is seeing a large number of MySQL engineers, consultants, and support engineers participating in the mailing list discussions and in the refactoring work.

There are now 34 folks chatting over on the Freenode #drizzle channel, and the …

I came across this error recently when trying to modify the data type of a column.

ERROR 1025 (HY000): Error on rename of './sakila/#sql-1d91_5' to './sakila/inventory' (errno: 150)

Not the first time, and not the last time. A common problem with InnoDB tables, is the lack of information, you need to dig deeper with the following command (and appropriate security a well organized security profile will NOT have).

mysql> SHOW ENGINE INNODB STATUS;
