Grabbing a handful of wet, saturated sand, I let it dribble through my finger tips.  I watch each drop pile on top of the previous, draining away the water and leaving a new building block of solid sand.  Too much water and the previous drip will be washed away.  Too little and the sand cracks and refuses to hold together.  I watch the sand grow, getting into a rhythm that ensures just the right amount of water, without thought.

My thoughts are not on the mechanics of building a drip castle with sand.  Instead, I’m thinking of the spire that I’m building.  Can I build these two spires toward each other and form an arch?  Can I make this slender spire taller?

Frequently I fail and a part of the castle slides down, becoming part of the landscape again.  Or becoming a foundation for a new part of the castle.  No matter.  It’s the building of the castle that brings me joy–not the owning of it.  For I will never own it.  The sea soon comes and takes it away.

Last weekend, I drove six hours down to Floyd, Virginia for a Code Retreat organized by Gustin Prudner and led by Corey Haines.  There, I joined thirty-some people working in pairs and threes on Conway’s Game of Life for forty-five minutes at a time.  Then, Corey would call time, and we would wash away all traces of what we’d built.

Does that sound like a waste of time?

Some of you may remember that I started a house construction project. Things are moving very fast, now, and the actual construction may take less time than it took to get all the necessary permits. So far, the project’s about 100% over the time budget. And people say that software development should be more like the construction industry!

But the fact that the construction has run slower than expected is not the reason for this post. Neither is the fact that this project has been consuming a large portion of my attention, and hindering posts on this blog.

This post is about an example of refactoring found in the house construction domain. (Continued)
