Using abstraction to understand systems

I just stumbled on a very well done interactive post by Brett Victor explaining the ladder of abstraction concept and how to put the idea to work exploring and understanding complex systems.

The most exciting engineering challenges lie on the boundary of theory and the unknown. Not so unknown that they’re hopeless, but not enough theory to predict the results of our decisions. Systems at this boundary often rely on emergent behavior — high-level effects that arise indirectly from low-level interactions.

When designing at this boundary, the challenge lies not in constructing the system, but in understanding it. In the absence of theory, we must develop an intuition to guide our decisions. The design process is thus one of exploration and discovery.

Great use of interactive elements to demonstrate the concept.

Drag and drop prototyping with HTML5

Pingendo, a native application for Windows and Mac, uses Twitter Bootstrap as a base for drag-and-drop HTML editing. I was just wishing this tool existed last week as I tried to beat Axure into working as well as hand-coding my own mockups.

If it’s as good as it looks at first glance, this could be a perfect tool for designers in engineering/business-process-heavy enterprise environments.

Engineers or authors?

Interesting post by Kurt Leafstrand comparing software development to writing and publishing rather than engineering:

So, here’s the insight I’m currently tossing around in my head: The problem is that software isn’t built; it’s written. The final product is not like the Bay Bridge. It’s like a novel.

Engineers are the authors. They start with an early draft (sometimes known as a prototype), an idea of the main characters (features) and the arc of the plot (use cases). They write a few chapters. They learn how the characters are acting and whether things are moving in the right direction. Then they go back and tweak the storyline a bit. They iterate.

Along that line of thinking, newspaper publishing is the original agile development method.
