Apollo Software — amazing collection of source code to the software behind the Apollo mission. And memos, and quick references, and operations plans, and …. Just another reminder that the software itself is generally dwarfed by its operation.

Habits of Mind (PDF) — Much more important than speciļ¬c mathematical results are the habits
of mind used by the people who create those results,and we envision a curriculum
that elevates the methods by which mathematics is created,the techniques used
by researchers,to a status equal to that enjoyed by the results of that research. Loved it: talks about the habits and mindsets of mathematicians, rather than the set of algorithms and postulates students must be able to recall. (via Dan Meyer)
