I'm back home from DrupalCon 2008 now - it has been a great event! I met a lot of nice people from the Drupal Community and learned a lot about this CMS. I've been very busy in uploading the remaining pictures from the event to my gallery - so here's for your viewing pleasure:

Continuent is probably best known for its database clustering technology for MySQL, as well as PostgreSQL, but the company has for some time had its sights set on expanding beyond open source databases and enabling horizontal database scalability.

It has just taken a major step towards delivering on both counts with the launch of Tungsten, its new stack of open source middleware technologies designed to enable low-cost databases to scale horizontally for database failover and continuity.

Tungsten includes includes Sequoia, the existing …

Hello and greetings from DrupalCon 2008 in Szeged, Hungary!

We (Thierry Manfé, Scott Mattoon and myself) are having a great time manning our booth and talking about Drupal, MySQL and Open Source@Sun with the nice crowd of Drupal Users and Developers here. Sun is a gold sponsor of the event and we're giving a number of sessions as well.

Today I gave my first presentation about MySQL Backup and Security - Best practices - unfortunately I ran a tad bit out of time at the end... The slides have already been attached to the session page, so you can read up on the last few things I was going to talk about. Feel free to contact me, if you have further questions!

Tomorrow I'll be talking about …

I have a small EC2 instance running with a 25GB EBS volume attached. It has a database on it that I need to manipulate by doing things like dropping indexes and creating new ones. This is on rather large (multi-GB, millions of rows) tables. After running one DROP INDEX operation that ran all day without finishing, I killed it and tried to see what was going on. Here’s the results of the first 10 minutes of testing:

-bash-3.2# dd if=/dev/zero of=/vol/128.txt bs=128k count=1000
1000+0 records in
1000+0 records out
131072000 bytes (131 MB) copied, 0.818328 seconds, 160 MB/s

This looks great. I’d love to get 160MB/s all the time. But wait! There’s more!

-bash-3.2# dd if=/dev/zero of=/vol/128.txt bs=128k count=100000
dd: writing `/vol/128.txt': No space left on device
86729+0 records in
86728+0 records out
11367641088 bytes (11 GB) copied, 268.191 seconds, 42.4 MB/s

Ok, well… that’s completely miserable. Let’s try …

A couple of articles have been published recently that point to a growing realisation/admission about the role that open source will play in the future of enterprise software.

In “The Commercial Bear Hug of Open Source” Dan Woods details the various methods by which open source has become increasingly commercial in recent years, while in “The Microsoft-Novell Deal and Trust in Princes” Bruce Byfield discusses the relationship between business and open source.

Neither article is perfect. Woods, in particular, appears to paint open source in the role of the glorious failure - failing to surpass traditional licensing models and being subsumed into the mainstream (a subject …

A classic Morecambe and Wise comedy sketch from the 1970s sees Andre Previn criticizing Eric for playing all the wrong notes while attempting the Greig Piano Concerto. Morecambe responds that he is in fact “playing all the right notes. But not necessarily in the right order.”

I was reminded of the sketch this morning while reading BusinessWeek’s article on the potential perils facing open source vendors today. It seems to ask all the right questions, but not necessarily in the right way.

The report suggests that while industry giants such as IBM, HP, Oracle and Intel stand to benefit from open source software, investor impatience could spell trouble for open source …

So, I wrote about the begining of our wild database issues. Since then, I have been fighting a cold, coaching little league football and trying to help out in getting our backup solutions working in top shape.  That does not leave much time for blogging.

Never again will we have ONLY a cold backup of anything.  We were moving nightly full database dumps and hourly backups of critical tables over to that box all day long.  Well, when the filesystem fails on both the primary database server and your cold backup server, you question everything.  A day after my marathon drive to fix the backup server and get it up and running, the backup mysql server died again with RAID errors.  I guess that was the problem all along.  In the end, we had to have a whole new RAID subsystem in our backup database server.  So, my …
