Thanks to Pillar and Chris Baker for their hospitality.
There was plenty of food and drink.
Pillar is always looking for good folks.

Jim Prior led a live refactoring session of code
from the Exercises in Programming Style stuff
that Chris Baker mentioned last month.

It was done in a Jupyter Notebook that you can review:

    style was something that emerged after constraint(s) were imposed
    potential literature:
        "the seeking of new structures and patterns
        which may be used by writers in any way they enjoy."
    E.g. "A Void" (La Disparition) by Georges Perec

constraints lead to creativity

Programming Styles
    Ways of expressing tasks
        How to divide task into parts and put them back together
    Exist and recur at all scales
    Frozen in Programming Languages

Saw huge amount of really bad code from 3 and 4 year advanced students

monads

The story:

    Term Frequency
    given a text file,
    output a list of the 25
    most frequently-occurring words,
    ordered by decreasing frequency
        exclude stop words and single letter words

Take Home
    Many ways of solving problems
        know them, assess them
        what are you trying to optimize?
    constraints are important for communication
        make them explicit
    don't be hostage of one way of doing things

How do you structure your thoughts?
how do you divide the problem?
How do you put it back together?

Spreadsheet Style
    how would you count words with excel?

Challenge for this month is to refactor a little program.

cheap selfie stick was not just one piece
the stick and part that holds smart phone were separate,
with standard camera threads to join them
made it easy to use gumby tripod to hold smartphone

Chris' VGA to HDMI adapter worked great
    allowed presenters to be with everyone else
    handled full 1920x1080 resolution
        LCD display on left showed full 1920x1080
        projector in middle showed full 1920x1080
            It's contrast, brightness, gamma might be maladjusted.
