  1. Organized Chaos Improving Your Multitasking Skills

  2. Reasons Not To Multitask • Takes longer to complete the

    first task • Overhead of switching between tasks lengthens completion time task 1 task 2 time without multitasking t1 t2 time t1 t2 t1 t2 t1 t2 with multitasking t1 t2 time t1 t2 t1 t2 t1 t2 with multitasking + overhead
  3. More Reasons Not To Multitask • Difficult or complex engineering

    problems require your brain to retain a lot of information all at once. A lot of analogies to computers here. • Continuous partial attention: you won’t see the details
  4. IRL Examples • New technology is combining multiple media sources

    • Texting while driving • Talking while watching TV • Eating lunch while making this presentation • Walking while talking
  5. Let’s Refute These Reasons • Longer task completion times: ◦

    Multitasking is a requirement, it’s part of the job. • Switching tasks takes time: ◦ Yes, but there are ways in decrease that overhead. • Complex tasks take a lot of brain space: ◦ Breaking up tasks into smaller pieces is beneficial for development ▪ aligns nicely with iterative development ▪ helps organize and modularize code • Missing details: ◦ Some tasks don’t need every bit of your attention
  6. Pick Your Battles • Don’t multitask on a task that

    needs all your undivided attention. Unplug. • Configure your projects so that they can be multitasked • Know your multitasking skills • Small bug fixes: plenty of attention gaps
  7. Does My Workspace Matter? • command+tab, use it much? •

    Headphone rule • Ask for a minute of time • Reduce peripheral attention when necessary (french music, techno, classical) • Proportion screen space to its priority
  8. None
  9. Working On Multiple Tasks Using the computer analogies: • Reduce

    the amount of memory in short term • Move unnecessary data from short term into long term • For the python fans out there: you have a GIL, be aware of it • Use transaction blocks • Use lists, not sets • Don’t go into swap • Follow common architecture and design patterns
  10. Context Switching Reducing the overhead of context switching: • Use

    analog sources for your list ◦ To do list ◦ Questions ◦ Roadblocks ◦ Priorities
  11. Bug Crushing To Your Advantage Reproduce ∙ Write Test ∙

    Find Offending Code ∙ Fix ∙ Code Diff ∙ Land ∙ Deploy • In the spaces between, switch to something else • Leave comments with hypothesis, ideas, questions • Think “out loud”
  12. Coding To Your Advantage • Pseudocode and leave notes in

    comments • Use stub functions to organize ◦ refactor as you go, don’t leave your code a mess
  13. Now.. Practice!
