Popular While Using Your Programming Skills to Make the
World a Better Place

5-15% use GPU clustersto analyze petabytes
in the cloud
85-95% send eachother spreadsheets
by email
Scientists
3
It Is Therefore Obvious That...
We should put more computing in the curriculum!
But it's already full
4
It Is Therefore Obvious That...
And even if we did...
...who would teach those classes?

If you build a man a fire,you'll keep him warm for a night.
If you set a man on fire,you'll keep him warm for the rest of his life.
— Terry Pratchett

Unix shell
Version control
Python/R/MATLAB
SQL
Make
7
What We Actually Teach
Unix shell => Task automation
Version control => Track and share work
Python/R/MATLAB => Modular programming

How It's Going

What We've Accomplished
● Honestly don't know● Anecdotally, save people 10-20% of
their time for the rest of their careers● And prepare them for petabytes and
clouds
15
What I've Learned
1. We know a lot
about learning
2. Most people
would rather fail
than change
3. There are lots of
gaps to fill
16
For Example

17
● Today's MOOC platforms don't support PI● Piotr Banaszkiewicz showed it's possible
github.com/pbanaszkiewicz/peer-instruction● Opportunity #1
18
The Jupyter Notebook
Text, math, code, and images
What hypertext was meant to be

The Jupyter Notebook

"collapsed": false

Good luck diffing and
merging this.
21
It Doesn't Have to Be This Way
Tavish Armstrong and others
nbdiff.org
Opportunity #2
22
Generalizes Well
First-class support for diffing and merging spreadsheets will get more scientists to use version control than
anything else we can do.

3 developers x 8 months (?)
(even if it's optimistic...)
24
Speaking of Version Control
● Git is an awful tool● git-man-page-generator.lokaltog.net● But it's the price people have to pay in
order to use GitHub
25
Speaking of Version Control
● A rational re-design of Git is possible and worthwhile
● Opportunity #3● Also generalizes well
Andreas Stefik and Susanna Siebert: "An Empirical Investigation into Programming Language Syntax." ACM Transactions on Computing Education, 13(4), Nov. 2013.
26
A Puzzle
● Thousands contribute patches to open source software projects
● Millions have edited Wikipedia
● Why don't people build lessons this way?
27
All Together Now
● We've shown it can be done● And that it's useful● This presents more opportunities
28
A Small Part of the Reason
● Slideshow formats aren't diffable either
● But HTML alternatives are impoverished
29
A Small Part of the Reason
● Neither can create web-native videos
● Proof: pause a video, highlight the text being displayed, and copy it
30
Solution: Browsercast
HTML slideshow...
...with start times for slides...
...and a player that syncs with audio
github.com/twitwi/deck.browsercast.js-demo
(Bonus marks for a GUI timestamp editor)
31
Advantages
● Plays everywhere
● Mobile-friendly
● Accessible!● Searchable!● Diffable! (ish)
32
To Sum Up
● First-class support for peer instruction● Diff for all! (Excel first)● A rational reconstruction of Git● Browsercast● Rocket science● Fill in the gaps
