Reading technical documentation
Begin with the overview, then find a complete example. Check the version attached to each reference and keep a note of assumptions. Return to the specification when an example leaves an important behavior unclear.
Reading Room
A collection of brief reading notes.
Notes that age well
A useful note carries enough context to be understood later. Include the problem, the decision, and the reason. Prefer a short explanation with a dated reference over a list of unexplained commands.
Working through a difficult book
Read in small sessions and write a few questions after each section. Revisiting those questions helps connect the material. A summary in your own words is a practical check of understanding.
