What have I learned about app design and development today?

Since the introduction to Loop statements yesterday, a deep dive on the topic today talked about:

  1. Loops are invented out of the virtue of laziness(!)
  2. There are 2 key types of loops in Swift, For-In loops, and While loops.
  3. A For-In loop repeats the same set of actions through each element of a sequence. And there are 5 key types of sequences — arrays, sets, dictionaries, letters in a string, and numbers in a range which can be half open or closed.
  4. A While loop repeats the same set of actions “while” a certain condition is true. And if one is not careful, a While loop could be trapped in an “Infinite Loop”, such as the Head Quarter of Apple Inc. at 1 Infinite Loop, Cupertino, CA 95014, United States.

What have I learned about journaling technologies today?

Just received the Clear Habit Journal this week in the mail after discovering it on Day 20. Unboxing and holding it in my hands today, there is such a sense that the feeling of paper is never replaceable by a phone or tablet.

There is something calming and real about the edges, boundaries, and touches of a piece of paper. When I close a paper journal, whatever written inside remains physical in existence, and feels every bit as concrete and tangible still.

In contrast, whenever I turn on a phone or tablet, there is a sense of infinity and overwhelm of the information and worlds it suddenly plugs us into. And whenever I turn off a device, the sense is one of a blackhole. As if nothing that occured there ever did exist.

In contrast again, when unless I am at home at my desk, I only want to carry a phone or tablet, never the weight of a physical journal. Why can’t I have both? =) What an opportunity to innovate and design.

As Bill Burnett and Dave Evans said about designers in their bestselling book, Designing Your Life,

“Designers love questions, but what they really love is reframing questions. … Designers imagine things that don’t yet exist, and then they build them, and then the world changes.”
