I’ve recently received one database admin’s personal list of DRBD’s perceived limitations. While I’m certainly the last person to say that DRBD is limitation-free (hey, it’s software), I’d like to address these specifically — because really, in my humble opinion, most of them aren’t limitations at all.

Weeks after Yahoo! CTO's resignation (or was he forced out :)), Yahoo! CEO quits. Unlike Google, Yahoo! turned to old media to lead the company. The results of course were way below par. Terry Semel was a controversial choice but one that at times, brought hope. At no time in Semel's tenure that hope seemed sustainable. Destruction of Overture, failed acquisitions like Web Jay and lack of effective strategy (yes Yahoo! Photos, yes Flickr!, no Yahoo! Photos).

Jerry Yang is himself stepping up to take charge. According to "The Google Story," this is exactly …

Not sure why you would want to but I've had several people ask me about VI emulation under Visual Studio.  Yes, Virginia, it exists.  Check it out here.  Will set you back $70 but if you really need it....

When I first learned that having an AUTO-INC column causes a table lock in InnoDB, I was surprised. Since that day, I have been warning just about everyone regarding this.

In addition to the AUTO-INC table lock, there seem to be some other conditions where table lock is requested. I am saying this because on some of my InnoDB tables, I am seeing "tables in use 1, locked 1."

Do you know of any other conditions that can cause InnoDB to request a table lock? I have heard that using REPLACE or UNIQUE indexes on MySQL 4.1.X can cause this behavior.

If you know of any other situation where InnoDB will request a table lock, would you please leave a comment or email me (softwareengineer99 at Yahoo).

As I find information regarding this, I plan to document it here.

I've actually been meaning to finish this blog entry for quite some time, and now finally had the chance. Recently, Brian Duff wrote an article entitled "If I Had 5 Oracle Wishes, They Would Be...". I thought the topic would be a good blog meme to start within the MySQL blogger community, so I'll go ahead and start it off for PlanetMySQL and see if anyone else chooses to pick up the topic and pass it on. So, here are my top 5 wishes for MySQL in the future...

The Modularization of a Core MySQL Server Kernel

Certainly, this particular idea isn't new at all. I discussed the concept with a number of people at the first MySQL Camp last November, and found some receptive ears. Additionally, I …

This weekend, Monty and I got together for a different kind of hacking session.

Instead of developing software, we were working on developing a set of rough principles and rules for running a Free Software/Open Source business. We both have a good amount of experience working with various FLOSS projects (like Mozilla, MySQL, PHP, etc.) and FLOSS companies (like eZ Systems, Mozilla, MySQL, Zend, etc.) and hope that we can put this experience to good use.

For me, this was a tremendous help - I’ve been putting off working on this for Foo Associates for some months now. It is much easier to work on meeting the needs of customers than it is to work on planning for the future.

The notes are still extremely rough, but both Monty and I want to post them so that people can discuss. Also, …

I’ll be attending the Openmind conference from October 2nd to 3rd and will be giving a keynote at the event.

Openmind is being organized by COSS, an interesting Finnish Free Software and Open Source development agency that helps Finnish and Scandinavian businesses and projects use and develop FLOSS.

Other keynote presenters at the event (that readers of this blog may know) include Jim Zemlin, Executive Director of the Linux Foundation, Aleksander Farstad, CEO of eZ Systems AS and FLOSS researcher Rishab Aiyer Gosh.

I also hoping that since Monty is in the area, he will also be able to attend.

I just received word that my proposal (which was to present my Age of Literate Machines presentation) for FrOSCon has been accepted.

I’m pretty excited - the event should be fun and it will give me a good chance to see friends (including a good number of my German MySQL colleagues)

Vertical advertising. I just stumbled upon The Problogger Job Board. They advertise it as such: post a job ad, for 30 days, at only $50.

People that visit the Problogger website, or job board, are definitely bloggers. Visiting the latter, means they’ve bought the hype that they can be a professional blogger, and make a living out of it. So what better way to hire journalists. Professional bloggers are no different to writers in a newspaper, magazine, and so forth. Turnaround times are quicker, the idea of formatting is probably a plus, but generally you’re a writer.

The FAQ lists the 37signals Job Board - $300 for 30 days. They’re a company that came to popularity thanks to a good blog, and Ruby on Rails. People that read the 37signals …

On the MySQL Conference & Expo 2007, I had the chance of meeting up with Paul (the author of PBXT) and Mikael. We briefly touched the topic of the BLOB Streaming Protocol that Paul is working on, which I find really neat. On the way back home, I traveled with Anders Karlsson (one of MySQL:s Sales Engineers), who is responsible for the BLOB Locator worklog and he described the concepts from his viewpoint.

Since I work with replication, these things got me thinking on what the impact is for replication and how it affects usability, efficiency, and scale-out. Being a RESTful guy, I started thinking about URIs both when Paul …
