It Went Viral

Tonight, I felt pretty awesome, tuning a server, live, while I basically watched a website promotion go viral.  Fighting just to keep the (1) server up, while almost ten thousands users were trying to register for the free stuff!  I’ve never watched organic growth like that, in real-time.  Thanks Scott Christian for letting me be […] Read More

Moving from Apache to Nginx

So far, so good. I felt like I was cheating on an old friend. I’ve been hosting website on Apache since 1996. It was on FreeBSD back then. I can’t remember the name of the data center I was using. I think they were out of New Jersey. I talked to the guy on the […] Read More

My month long battle with ORA-00060

The application that I’m working on is pretty huge.  I’ve touched maybe 25% of the actual code intimately in the 9 months I’ve been working with it.  Over a month ago, we discovered an issue in production that had an ORA-00060 error as the primary symptom.  I’m the guy that likes to fix the stuff […] Read More
