I oddly just realized now that Mozilla Firefox is not handling client-side image maps correctly as it should with a DTD of XHTML 1.1 Strict in text/html. I will not go into test cases unless one finds it necessary as everything has been laid out in the two links below. However, why has this not been resolved or is there a proper solution to this matter? I have not been able to find a answers and oddly this issue has been brought up back in 2001. One would think enough time has past.

Any explanation, comments, or help would be greatly appreciated.

So once again, Innovate Europe starts in Zaragoza, although this time a bit different. There is a “Master Class” which started yesterday with a roundtable called “Thriving in the Crisis”. We could listen to some of the experts which will be sharing their experiences at the master class, like David Sifry, Marten Mickos, Yoav Leitersdorf, Maximilian Niederhofer, Barak Berkowitz, Madeline Duva, and Mike Rogers, conducted by Ignacio de la Vega .

Ignacio and Javi will be attending the Master Class this week, but I also joined the roundtable (this was the only part free and open to the public) and took some pictures.

I recently ran into a sort of gotcha with PBXT that I thought I would share. Just as a fun exercise, I was trying to figure out the variances in data-sizes across different table engines. As you would expect, InnoDB tends to consume more space than MyISAM and ARCHIVE tends to reign supreme when it comes to consuming tiny amounts of space. What surprised me, however, was that PBXT consumed more than InnoDB. A lot more.

In any case, I went ahead and logged a bug on the issue though that may have been a bit premature. Paul was kind enough to provide me with a great explanation as to what was going on (which, by the way, was also explained at his talk on PBXT that he has offered at the last few MySQL Conferences). PBXT stores table-data in a log based format. However, data can be stored in both a fixed-width, as well as variable-width format. When a new table is created in PBXT, the average size of the table is estimated based upon the …

Last night at the North Texas MySQL Users Group meeting, Jeff Martin from ReportMill.com showed off their DataBox tool.

This is a Java based tool for developing rich Internet applications. It has the hooks to create MySQL databases and link the data to applications. Jeff demonstrated creating tables from scratch, importing files into a database, and then using that data in a full function application that took a very shot time to create. It is much faster than compatible frameworks and features a rich set of Java enhancements for effects.

So if you quickly need to get from raw data to full application, check out DataBox.

I will be hosting a webinar on May 7 about how companies like Wikimedia and Smugmug are using Open Storage and MySQL to deliver rich media (photos, videos) to their users. You can view the webinar live or on demand here.

Javier Soltero, former CEO of Hyperic, has maintained that the sale of Hyperic to SpringSource was driven by discussion between himself and SpringSource CEO, Rod Johnson, but the fact that the companies shared investors - Accel Partners and Benchmark Capital - no doubt accelerated the deal (and I wonder whether either could have afforded to acquire the other without shared investors).

When examining the open source vendor landscape it is tempting to imagine that the combined total could be bigger than the sum of its parts - that a combination of many open source product specialists could mount a challenge to Red Hat and Sun to claim the title of biggest open source software vendor.

Benchmark and Accel are among …

If you’re using the Federated engine, here’s something important to remember (apart from the usual advice of “please don’t”). If you need to change the structure of the remote table, always remember to update the Federated table. If not, when you try to use the table, you’ll get this error:

mysql> SELECT * FROM foo;
ERROR 1030 (HY000): Got error 1 from storage engine

This error isn’t really helpful. The problem is, the Federated engine only checks that the remote table structure is correct when it initially connects. Once it has connected, no more checks. When you restart the server, you get a much more helpful message:

mysql SELECT * FROM foo;
ERROR 1431 (HY000): The foreign data source you are trying to reference does not exist. Data source error:  error: 1054  'Unknown column 'b' in 'field list''

Also, keep your eye on the …

As I was driving with a colleague in California a couple of weeks ago during the conference, the topic of conversation turned to the notion that Percona and the rest of the MySQL community really need the presence of a central entity that provides a recognized home for the MySQL server. The conversation went something like “I was talking to so-and-so, and he said, you know, you guys really need Sun/MySQL, because without the mother ship, things will fall apart and your own business will fail.”

I happen to believe this is FUD, and that the reverse might actually be true. (This is one reason why we’re competing head-on with MySQL.) Having a “mother ship” is in the long run, a very complex scenario to fully understand. There are all sorts of causes and effects that play out in subtle ways. I honestly doubt anyone can really …
