Pairing for a better future
- 5. Basic: How to pair
- 6. Exercise: 15 minutes drawing • Pair draw • Pen switches hand every 3 minutes • Theme: “Movement in the wild”
Notes de l'éditeur
- 1 driver 1 navigator Simply put, pair programming is “two people working together at a single computer”. The practice has been popularized by a software development methodology called Extreme Programming (XP), and a number of researchers have studied the effects of incorporating pair programming into introductory and higher-level computer courses.
- better code => pair pressure (don’t let the other down) => code and fix natural tendency (slot machine example) learning sharing knowledge better thinking: two brains are better than one, bouncing ideas Rubber duck debugging or the expert theory (deep questions) there is ALWAYS something to learn, to teach. become better at articulating your thoughts reduction in coordination efforts managing N/2 divs => managerial argument Improved resiliency to interruptions (although potential internal interruptions) But we have code reviews… => choices have already been made that could have been better with another brain, chances to influence these choices are gone.
- 1 Driver, 1 Navigator Every fifteen minutes or so (or a full pomodoro), the pair switches roles by sliding the keyboard over Ping pong with TDD : write test, other implements and write another test
- passivity: active engagement at all times running commentary going silent => programming out loud fear (of judgement, fixed mindset) trust confidence imposter syndrome intrusion on personal space => use pomodoro, timeout pairing is NOT mentoring, both should be considered equal remote pairing culture
- Abstract: build trust make each other look good : Agile Australia the Spark team No blocking No wimping No hogging adopt a growth mindset : Agile Australia Peter Heslin - leveraging mindsets for effective leadership example with kids exercise : you are smart vs you worked hard embrace ambiguity give space be humble and accessible forget pride, it will only get in the way => equals don’t judge use empathy, be compassionate don’t fear/induce fear -> avoid bashing Concrete: personal hygiene alternate to find the speed of the pair, ideally a bit faster than the slower use pomodoro/timeout to ensure you have breaks, enjoy short break together, long break separately. discuss all the things : announce what you intend to do, and why, ask for feedback early, code out loud use the pair programming ping pong pattern visualize => sequence diagrams give feedback regularly slice thinly, it will boost confidence (plan well) EXERCISE: Pair slice a story, must have 8 to 18 steps : Alistair Cockburn Elephant Carpaccio
- Profiling can help you know how to be a better pair if you can’t read people Lots of profiling tools out there, those aimed at interaction are obviously a better choice, ex: DIsC Remote pairing => tools sharing screen (screen hero) Better code => better environment for all of us (Devs Cultivating empathy Memorable : Best/Worst experiences: ask the crowd, discuss
