The Programmers Brain

Notes from The Programmer's brain by Felienne Hermans

1. Decoding your confusion while coding

  • Code is a mental decoding process.
  • Confussion involves cognitive processes.
  • Confussion processes:
    • Lack of knowledge: understand what are you doing.
    • Lack of information: understand how this is happening.
    • Lack of processing power: be able to execute the code in your brain.
  • Cognitive processes associated:
    • Lack of knowledge: LTM Long term memory.
    • Lack of information: STM Short term memory.
    • Lack of processing power: Working memory.
  • The three cognitive processes work together when you're coding.
  • LTM could be the knowlege and experience using a language intructions.
  • STM could be the variables used to implement a piece of code.3

2. Speed reading for code

  • "Programs must be writter for people to read and only incidentally for machines to execute" Harold Abelson.
  • There is often a lot of focus on producing code.
  • STM is limited (6 slots).
  • Chunking technique to read code: read a piece of code for 3 minutes and try to remember it. Chunks help to structure your interpretation.
  • Iconic memory: space to store sensory memory.
  • Iconic memory can be procressed in the STM.
  • Iconic exercise: look the code for a short time and the reflecting on what you have seen.
  • Chunkeable code is about use conventions and patterns to help you to process code faster.
  • When code contains comments, programmers will take more time to read it. (How do we read algorithms? Martha Crosby)
  • Beacons are a piece of code contains certain data or approach.
  • Beacons are a trigger for programmers to confirm or refute hyphotesis about the source. 😲
