Thanks to Pillar and Ben Rogers for their hospitality. It was fun to watch the
astonishment and disbelief of an early newcomer to the Forge, to what pair
programming and test-driven development is, and the amenities for employees.
That astonishment and disbelief was hard to dispel even after Ben confirmed
things.

It was interesting to watch pair programming from 10 meters. 
One could see that both screens had the same content. 

Thanks to Brian Costlow to providing the food from City Barbecue.
I had not had their stuff before PyOhio, and am thoroughly impressed.

I did not know one could assign to slices.

    >>> a = range(5)
    >>> a
    [0, 1, 2, 3, 4]
    >>> a[::2] = 'bar'
    >>> a
    ['b', 1, 'a', 3, 'r']
    >>> 

more on that later.

Cisco telnet (yes, telnet, really, in 2014!)

Norman Bird presented Django.

Eric Floehr presented on several rather simple things that many of us did not
know. His notebook can be viewed at
http://nbviewer.ipython.org/urls/dl.dropbox.com/s/i19j3gk1yrahna1/arrays-etc.ipynb?dl=0.
For each cell, predict what the output will be before you 
look at the output. 

    a=range(5)
    a[1::1]=['some', 'thing'] # insert
    a[-1:]=a[-1]
    collections
    deque (pronounced "deck") O(1) performance
    files = glob.glob('/long/path/*.foo')
    files.sort()
    column = column + 1
    can be simplified as column += 1, which is easier on my brain

Jim Prior gave a minor presentation on using divmod() to convert many minutes
to hours and minutes and to convert centimeters to feet and inches. 
His presentation is in the last two non-empty cells of Eric's notebook above. 

Shareef Dabdoub gave a presentation on ipython (and notebook) magic commands.

import angles

I don't see anything in angles that does what I'm to do 
above. Having the input and output in floats is part of 
the definition of the problem. angles solves different 
problems.
