Some time ago I posted a compilation of applications and programming languages that provide an API to connect to the MySQL Server. As it turned out, I forgot a few that I would like to mention here:
I'm happy to announce that the schedule for OpenSQL Camp 2009 (European Edition) has been published on the FrOSCon timetable now. We have a great selection of topics and speakers, so don't miss it! OpenSQL Camp is a subconference of FrOSCon, the Free and Open Source Conference, which will take place on August 22nd and 23rd in St. Augustin, Germany.
The admission fee for the entire conference (both days, incl. OpenSQL Camp) is 5 EUR, you can pre-register here until August 10th (and if you do so today, you will still get a free T-Shirt as well!). Of course, you …
[Read more]We've now published a new set of binary packages including the extended GIS functionality from the mysql-5.1-wl1326 source tree.
This release is based on the MySQL 5.1.35 code base and fixes the bugs mentioned below. It includes some improvements to the GIS functionality as well, so please use these packages for future testing of the MySQL GIS functionality.
The following GIS-related bugs were fixed in this version:
The Call for Papers for the OpenSQL Camp 2009 (European Edition) has ended yesterday — we received 27 excellent session proposals from various Open Source Database projects. I would like to say a big "Thank You" to everyone who submitted a talk! In the beginning I was a bit concerned that the conference would become too MySQL-centric, but this fortunately changed in the last few days.
Sadly we now have more than double the amount of sessions than we can actually host, which means that we will have to review and vote on the sessions to distill the final program. We've formed a small committee that will perform this task (currently consisting of …
[Read more]A core economic principle is the Complementary Good . In short, when two or more things are used together, they are complementary. When the price of an item goes up, the usage of all of its complementary goods goes down. Similarly, if the price of an item goes down, the usage of all its complementary goods goes up. An example is the computer printer. Printers and ink are complementary goods. Proprietary ink products are extremely valuable—at one point ink delivered 60% of HP’s profits —so HP, understanding the principle of complementary goods, practically gives away printers because they make money on the ink. This is the classic razors and blades business model.
Businesses want to lower the cost of their products, while maintaining or improving their margins. …

[Read more]Yesterday I merged the BlitzDB tree with Drizzle‘s trunk for the first time in a long time (yeah…) and discovered some interesting changes made to the storage subsystem while I was away.
Previously all functions that caused an action to the storage engine was a member of the handler class but various things like table creation and transaction related functions have now moved to the StorageEngine class. These changes are somewhat drastic but makes good sense for Drizzle to grow further since it makes the subsystem easier to understand and frees Drizzle from the interface design that was strongly affected by MyISAM. For those that are interested, the StorageEngine class is located in “drizzled/plugin/storage_engine.h”.
For me it was pretty easy to update BlitzDB to work with the new …
[Read more]Today, I would like to introduce “skyload“, a small project that I’ve been working on for the last couple of weeks. In brief, skyload is a libdrizzle based load emulation tool that is capable of running concurrent load tests against database instances that can speak Drizzle (and/or) the MySQL protocol.
Something I’d like to emphasize here is that, skyload is not a replacement for mysqlslap or drizzleslap since it only provides a subset of what they can do. As I’ve stated on the project description, skyload is designed to do a good …
[Read more]I've now posted all the current talk submissions to the OpenSQL Camp Wiki. A big Thank You to everyone who contributed so far and helped us to bang the drum for this event! If you haven't heard about OpenSQL Camp yet, it's a subconference of the Free and Open Source Conference (FrOSCon) in St. Augustin, Germany, which takes place on August 22+23. The topic of OpenSQL Camp is "Open Source databases and related technologies" and we're looking for interesting presentations in this field.
As we have 12 session slots to fill, we still have room for at least 6 more submissions! It's also a tad bit MySQL-centric at the moment, that should definitely change! We would love to get some more diversity to cover a broader range of Open Source Database technology.
So please submit your talk proposals and help …
[Read more]Last week I gave a MySQL University Presentation about how to contribute code to MySQL. This time DimDim did not fail to record the session, even though there is a funky overlap of audio from Stefan Hinz (the moderator) and myself at the beginning. I had a bit of a slow start into the presentation, because of a very nasty headache that plagued me that day. But we had a lively discussion at the end and I hope it was useful to the participants.
In case you have missed it, you can now watch the playback or download the session slides:
