Creating a portable JDK with PowerShell

At times, I’ve found myself wanting to have a specific JDK available without installing another version of Java. Past reasons include wanting to test multiple Java versions on the same system or needing to use a Java tool (ex. JConsole) without installing additional software. With a small PowerShell script and 7-Zip installed*, you can easily […]

RavenDB and MongoDB: Not easily interchangeable (at least not always)

On a recent internal project, we experimented with various NoSQL database back-ends. The project had used MongoDB since its inception. However, due to some memory issues, we wanted to evaluate other document database back-ends. In the end, we selected RavenDB for evaluation. The good First, I want to mention the things I liked about using RavenDB: There […]

Running Lean Startup Experiments Internally

When building a business or software, it is easy to make assumptions about what the market will want or how users will interact with your product. Recently, the concept of the Lean Startup Experiment has emerged to help us explicitly acknowledge these assumptions and construct small experiments to validate our assumptions. Here at SEP, we […]

I come from JavaScript, where regex literals and uncomplicated functionality make using […]

What happens to all those startup weekend projects?

We do startup weekend twice a year.  The outcome of which is 2-5 things.  These things are actually a couple things.  They are all software (at least to date, more discussion on that is coming).  Some are prototypes, proofs of concept, or MVPs.  The other thing that all of them are is SEP assets.  Like […]

Managing Distractions

I’ve recently started to practice the pomodoro technique.  Holy F!  This super simple practice has uncovered how much time I completely waste in a workday (not to mention my non-work time). I feel like I’m cheating myself and my customer (read employer), so I’m going to do something about it.  I’ve never read much of […]

Yet Another Pomodoro App

No, it isn’t called YAPA. Basically, I wanted a gentle introduction to the Pomodoro Technique, so I thought, what better way to introduce myself to it, than to build a pomodoro app while pomodoro’ing (new word, probably). So I whipped up an app that uses some of the fancy taskbar features of Windows 7.  If […]
