Hacking Open Source

Open Source means that the source code is open. There are many inferences that can be made from this, and many stereotypes that can be applied, but in the end, all it means is that you can read the source code as well as use the binaries. One of my team’s current tasks is to restore a backup (using InnoDB Hot Backup, and compressed) from a client’s production machine to a development instance…weekly — thus we want to automate it. We got everything going well, except uncompressing the production backup and applying any logs (with ibbackup).

Why is Database Security So Hard?

I was recently asked a question by someone who had attended my Shmoocon talk entitled “Why are Databases So Hard to Secure?”. (PDF slides are available). I was going to put this into a more formal structure, but the conversational nature works really well. I would love to see comments reflecting others’ thoughts.

The Sun Comes to Boston, Join the Live Videocast!

On Monday, March 10th, Sun makes a stop in Boston on its world tour of “Mashup Meetups”. If you can’t make it in person, join us on the live ustream videocast.

Good Database Design is Mightier than Hardware

Have you ever heard the one about throwing hardware at a software problem? I have this nifty RAC system that supports some very public and very mission-critical apps, and one day (it was Sunday night) it starts choking. We’re getting enqueues. Slowly they start climbing. Ten nodes came to a crashing halt. I have now seen a ten-node RAC cluster come to crashing halt and completely lock up. Why, you ask? A simple SQL statement: DELETE FROM a WHERE b=c AND d=e;.

Working at Pythian: 3 Months In

I have been a MySQL DBA at The Pythian Group for three months (and 2 days) now. At most companies that is the probationary period, and I am still here, so that is a good sign….. So, after three months, how do I like it? Glad you asked!

Hotsos Symposium 2008 — Still On

The symposia is still ongoing and my head is slowly filling up — relieved from my presentation, finally, I’m able to focus on others’ sessions. I attended Wolfgang Breitling’s presentation on “Active Statistics”. He provided a lot of insights into statistics gathering options and emphasized lots of new features in 11g. Have a look at my post to read about some of the other great presentations I attended.
