It’s one of the most iconic scenes in American film – Roy Schneider’s character is chumming the water and sees the shark they are hunting. The massive size of the fish causes him to comment, “We’re gonna need a bigger boat!” It’s shark week, and I was struggling with inspiration for blog posts, so apologies […]

Putting the Cart in Front of the Horse

People are always asking me, ‘Jeff, what’s going to be in the new version of X?’ or ‘Jeff, what’s new in X?’ or ‘Jeff, what’s wrong with you?!?’ If I’m feeling particularly chippy, I’ll reply something along the lines of ‘How well do you think you’ve mastered the current version of X?’ If you haven’t […]

They Just Write SQL Statements

“Those people are fine, they JUST write SQL.” I often hear this in the context of visiting customers and offering to provide training (and yes, software) to their database users.

What Databases Should You Back Up?

Some of my earliest memories involve trips to the dentist when I was maybe 3 or 4 years old. To this day, my blood pressure rises whenever I go in for a simple cleaning. There’s a particular poster I can’t seem to get out of my head, like a bad 80’s song. The intent was […]
