Navigating Mid-Success
When you start a startup, you get pushed off the side of a cliff with a bag of aerospace parts.1 You hope they are the parts for a spaceship, and they look like they might be, but it’s impossible to tell when they’re all in a bag.

I'm Loyal to Nothing Except the Dream
There is much I take for granted in my life, and the normal functioning of American government is one of those things. In my 46 years, I’ve lived under nine different presidents. The first I remember is Carter. I’ve voted in every presidential election since 1992, but I

Most packets were being dropped and the throughput was much lower than normal, but some were still making it through. The hypothesis is that occasionally the…

Over the last couple of years I've been doing talks about running Oracle databases in the cloud. In both my talks and articles I refer to the Licensing Oracle Software in the Cloud Computing Environment document.

Shutting down FTP services
