Use 4 main colors or so. 90pt–300pt font, 150pt average. Use words as shapes; use very few words. Repeat visual patterns to structure: colors, symbols, badges. Recapitulate before moving on.

    Working Effectively with Legacy Code

Michael C. Feathers
Notes by Jeremy W. Sherman, 14 Oct 2013.
Chapter 11: I need to make a change. What methods should I test?

Use effect sketches to figure out where to target your characterization tests prior to making changes. Big fan-in means a big bang for your test-writing buck.

Prior to changing, write characterization tests to pin down existing behavior.
Characterization test: A test that characterizes the actual behavior of a piece of code (186).

“Legacy”

What is legacy?


Often an insult, but how odd, not like that in normal English (cf. inheritance).
Also perhaps defined as “as opposed to its alternatives, it’s the software that actually works”.
