4 image data: multi-channel multi-slice multi-timepoint Need for custom GUI
code
5 Math, binary logic, and language syntax are the small
and easy parts. Small programs are easy to create, but it’s hard to grow and maintain them. Spec/design first Lessons learned

7 1995: Delphi 1996: html, (t)csh, emacs 1997: IDL, bash,
latex 1998-2010: IDL, C/C++, bash, perl, python, php, sql, vim, svn/git 2010-2016: python 2016-now: python, ruby, js, java (+ TDD, BDD, CI/CD,…) programming experience (paid)

10 http://disenthrall.co/complexity-is-easy/ Complexity == “software gravity”
11 https://en.wikipedia.org/wiki/Apollo_Guidance_Computer AGC, 1969 ~100’000 SLOC 1400 person-years Space Shuttle,
1981 > 1’000’000 SLOC Windows NT 3.5, 1993 > 7’500’000 SLOC Mac OS X (tiger), 2007 > 86’000’000 SLOC
12 0.1 MSLOC ~= 1.5m 10 MSLOC ~= 150m
13 Invest in communication and social skills (working effectively in
teams) Invest in simple tools and pragmatic development practices How to handle complexity?
14 “ Programs must be written for people to read,
and only incidentally for machines to execute.” — Hal Abelson
15 Proper naming (clarity beats cleverness) - use intention-revealing names
- avoid disinformation - use pronounceable names
16 hello FizzBuzz
17 refactored FizzBuzz
18 Linguistics is more important for programming than math! Communicate
in code with others Listen to your own code
19 Executable specifications are much more useful than requirements docs
and architecture diagrams.
20 Building the right product requires communication with all stakeholders
Working together: pairing
“For an idea to go from someone’s head into the
computer it must go through someone else’s hands” — Llewellyn Falco Working together: mobbing
23 Tools: plain text
24 Tools: command line
25 Tools: text editor
26 dev practices: TDD
27 Can it be taught?
28 Can it be taught?
29 Learning is not compulsory… neither is survival. — W.
