/ aptitude-why

The aptitude why command is awesome. At a glance, it tells you the whole dependency tree that led a package being installed, starting with the user’s action:

chromakode@ardent:~$ aptitude why liboxideqtcore0
i   unity-webapps-service Depends webapp-container
i A webapp-container      Depends webbrowser-app (= 0.23+14.04.20140428-0ubuntu1)
i A webbrowser-app        Depends liboxideqt-qmlplugin (>= 1.0.0~bzr490)
i A liboxideqt-qmlplugin  Depends liboxideqtcore0 (= 1.0.4-0ubuntu0.14.04.1)

Every package manager should be able to answer that question so simply.

/ leaps


There’s a lesson I seem to repeatedly forget, applicable to both life and design, in the nature of leaps forward. By “leap” here, I refer to an evolutionary change in the quality of an experience or approach which simultaneously solves many problems at once. The big “ah-has” that transform entire problem spaces and change the ways we think about possibilities.

A leap typically has the ability to take things we knew would be good, but opens them up in ways we couldn’t imagine before. For example, the potential of smartphones was long known before they became widely available. Authors and researchers imagined the possibilities of portable computers and ubiquitous connectivity decades before they became everyday utilities. Sci-Fi predicted things like the internet, Google, widespread social networking, and cryptocurrency. However, what it didn’t predict is the things that come after. The results of the leap.

As designers and engineers, we are constantly asked to quickly sort through possibility spaces, finding the good or elegant options. When searching a possibility space, we often use heuristics, basing our perception of options on experience or existing data that models expectation. Leaps obscure the options that these models fail.

Sometimes you can’t measure an experience after a leap based on what has come before it.

Why did social networking take hold when it did? Why did YouTube and Netflix start to work after so many video streaming services failed? Why are peer-to-peer sharing economies like Uber or AirBnB working now, rather than 10 years ago? Many people felt certain all of these things would eventually work, but why now? It seems easier to look back and remember the reasons these things wouldn’t work, rather than notice the changes which allowed them to.

Perhaps the reason leaps are so difficult to pin down is that their effectiveness comes from a lot of little changes, rather than a few big ones that humans find easier to reason about. Many small reductions in frictions that touch our lives and the lives of others in little ways throughout our day.

I often make the mistake of forgetting leaps when I judge a new idea. While it is necessary to be able to rapidly weed out bad ideas when searching, I miss good ideas too because I didn’t see the leap. And there’s the crux of the problem: many of those little reductions in friction can’t be noticed until you try.

A leap of faith? Or rather intuition?
