Abstractions II

Day One

Kill All Mutants

  • Mutation testing

    • mutates code with the goal of generating test failures
    • checks for meaningful code and strict tests
    • each change to our code should make at least one test fail
    • at least one unit test failing on a mutation is "killing the mutant"
    • First proposed in Richard Lipton's "Fault Diagnoses of computer programs" (1971)
    • Difficult to interpret results, and very CPU intensive
    • Python - cosmic-ray, mutmut, xmutant
    • JS - stryker

Maintaining a Legacy Haskell App as Not-Yet-Experts

  • Migrated from a haskell app in in frames within wordpress to a haskell app serving wordpress content via the wordpress api
  • The "Genius-Oh-No Cycle"

  • Chesterton's Fence

    • Understand why a thing is the way it is before you try to change it
  • ~3% of functional programmers are women

  • Things that helped

    • Pair programming
    • TDD (invert the cycle)

    • RFCs

      • Can be totally casual
      • Sketch out a larger idea and ask for input from the team

Measuring the Human Impact of Software Best Practices: A Story of CSS and Empathy

  • "The Tyranny of Pay-as-you-go Internet"
  • Worked at Mighty Ai (training data as a service), acquired by Uber
  • Stuff in the talk happened before Uber

  • microaggressions and microaffirmations

    • "you guys" vs. (friends, folks, participants, peeps, illustrious heroes, party people, yinz)

  • microaffirmations, a guide

  • micro-tasks in a webapp to generate vector images

    • $0.03 to $0.05 USD
    • Large base in Venezuela

  • community members raised concerns about data transfer

    • forgot ota internet was paid by the megabyte
    • didn't know the ost per megabyte
    • didn't know there was such flux in data access costs
    • asked them to take a literal loss in order to participate in the beta test
    • I assumed an experience largely consistent with my own

  • CSS is a tax

    • 1.3MB of css vs 34KB after refactoring
    • Movistar pricing: 0 MB included, each MB is $5 (5,00 Bs (bolivars))
    • 92 deployments, only 9 changed the CSS, every one of them re-generated the bundle and busted the cache
    • 8 downloads @ 1.3MB (52Bs) instead of 2 at 34KB (0.34Bs) just for CSS
    • This is an ethical issue
  • ask, listen, believe, then act

“Testing” - You Keep Using that Word, but I Don’t Think It Means What You Think It Means!

  • Testing is generally re-defined by every organization to fit their culture and needs
  • Easy to explain why an acceptance test works, harder to explain what the utility is that you get out of a unit test

  • An opinionated view of testing

    • automated testing is the single biggest factor in determining how fast you can ship code
    • You have to build up tests in layers and spend time in the right places
    • Teams that test write code with better structure focused on interfaces and low cyclomatic complexity

  • Pit of Despair - AKA "Test Environment"

    • Don't want to be dependent on the state of the environment to test that your code works
    • Useful for UI/UX exploratory testing, load testing, deployment testing

  • What can we do

    Unit tests
    Test the smallest units at the function/method level
    Integration/Component tests
    testing the composition of two functional units or external dependencies that achieve a larger operational function (reduce the number of variables, not increase)
    E2E/Acceptance/UI/API Tests
    Testing features with all required components integrated together but some can be mocked

  • Test Pyramid

    • low cost, fast run vs high cost, slow run
    • automated unit, automated integration, automated ui/api, manual ui/api

  • Fun tests

    • Writing good tests can be as challenging as writing good code
    • You will write more (2-3x) test code than feature code
    • Testing can be cathartic

  • Strategies for testing

    • Legacy code by Michael Feathers
    • Consider frameworks and libraries that lend themselves well to testing
    • Findexamples for what you want to do
    • Keep functions small and purpose-built - If it is hard to test, it's probably too big!
    • Limit conditional logic in a single function to 3 levels at most
    • Test ALL error conditions respond as expected
    • Use stubs, mcks and test doubles to simulate expected inputs and outputs
    • Limit integration/component tests to two actors (mocks for all others)
    • Create interfaces for components so that they can be mocked
    • Store test-case data with your tests
    • It's NEVER too late to start writing tests

  • Lightning Sand - AKA Microservices

    • The idea is to be (and stay) loosely coupled to the rest of the architecture, minimizing dependencies when testing is key!

  • Strategies for Microservice Testing

    • Don't be QA for services you depend on - trust their interface
    • Use service mocks for external dependencies
    • Write testing libraries/harnesses that other teams can use
    • Automate all of your tests - Without a UI you only need robots

  • What about non-functional tests

    • Every organization needs to evaluate whether that testing is necessary and correct for them ($$$)
    • Collect detailed metrics at service boundaries
    • Abstract out service-level concerns like back-pressure, retries and complex routing

How Games Can Inspire Great Application UX

  • NOT gamification (don't be on the addictive side of things)
  • Video games like the word "juicy" (visual impact on input)
  • Video games create tension, apps remove it

  • Ralph Koster (Book: A Theory of Fun)

    • Applying the lessons in the book to UX

  • Games present story, players create narrative

    • Standalone features vs a journey

    • The Mac story arc

      • Sound
      • promise
      • model
      • depth
    • Our story isn't the user's narrative

  • Games are fractal, not linear

    • Games are made of games
    • Each level has its own motivation, feedback, and learning
    • The deeper you go, the more profound the effect

  • The Learning Loop

    • Intent -> Action -> Result
    • Mental model -> affordance -> feedback
    • "Fun is just another word for learning" - Ralph

    • Mario 1-1

      • move (jump over) -> opening (jump into bricks) -> attacking (jump onto an enemie)
      • "That's how we make games at Nintend: we get the fundamentals solid first, then do as much with that core concept as our time and ambition will allow. As forthe courses and enemies, those actually came at the very end, they were done in a single burst of energy…" - Shigeru Miyamoto
      • Nintendo does this all the time
    • "Desktop has much better loops than mobile" - Ralph

  • Affordances

    • BotW stamina wheel - training you to take the better path
    • The SonicFinder, An Interface That Uses Auditory Icons

    • Mobile import is impoverished

      • Pinch
      • Tap
      • Long press is a hack!
    • Can't find any examples of gracenotes in apps
    • "It's not the flashy trick that matters, but the rigourous application of multiple types of feedback in both important and trivial ways" - Ralph

  • Hintiness

    • Hints / Affordances
    • Affordances reinforce the loop you're on
    • Hints move you to a new loop
    • Navigation (Disney weenies, always seeing a central place in a park, ensuring sight lines)
    • Hintiness prevents "bottom feeding" (getting stuck at one level, not making progress and doing new things)
    • Simple, light, patient examples showing how things can be done

  • Pacing

    • Games work incredibly hard on the first step
    • Here is a toolbox vs learn this first

  • Physics

    • Don't use physics (simple algorithm)

    • Collision detection

      • Contra uses point vs rectangle detection

        • The player is always the point, where it can be hit it is a rectangle in relation to the point

  • The NES does not have a random number generator (3 optionsin increasingorder of stupidity)

    • Tetris: Do it with math (16-bit fibonacci linear feedback shift register)
    • FF: (Nasir Gebelli, contractor) a lookup table of 256 random numbers

    • Contra: a single global 8-bit value that increments by 7 whenever the game is idle

      • The demo uses prerecorded actions, it can play out differently

  • Saving progress

    • Password systems

      • DQ2 in Japan used a "poem"

    • FDS

      • Shut down due to ease of piracy

    • Battery-backed memory

      • "Hold reset" - power issues could lead to corruption
      • Write multiple times with CRC

  • "Embrace the stupid"

    • Is it close enough, and much more efficient?

Overcoming Challenges: An Attitude of Iteration

  • "The Look" (first date story)

    • If you're different and it shows, it's assumed every problem in the book belongs to you
    • "You're not good enough for her" or "That's the saddest thing I've ever seen"
    • (context: one finger on each hand, one toe on each foot, 4/5 kids share this trait)
    • "Man, I'm different"
    • "Things are gonna be a little challenging for me, aren't they?"
  • We are all challenged
  • How you deal with that challenge is the model by which everyone else is going to deal with it
  • 50/50 chance of the genetic condition being passed on (5 fingers, or something else)

  • You have to make the choice of how to deal with it

    • Can't force children to make a decision, they have to make it on their own
    • It is a blessing, not a curse
    • It is what it is
    • It'll never be what it isn't

  • No excuses

    • "I can't do x yet", not "I can't do x"
    • We have to adapt
    • Never tell kids they "can't do x",but "it's gonna be hard, you're gonna have to figure it out"
  • Have fun
  • Sometimes life is hard, but you've still gotta go on. you try again, and you try again.

How Live Coding Changed My Life

  • Volunteer live coder for freeCodeCamp

  • How I got started

    • Paid for private github repos rather than letting folks see my code
    • "I make a lot of mistakes and I am a full time dev. Maybe it would be helpful for beginners to see that."
    • First streams were really bad and nobody watched
    • Asked for help on the freeCodeCamp forum

  • The community

    • all ages, locations, and skill levels
    • eager to learn and contribute
    • overwhelmingly positive
    • always learning and trying new ways to do things
    • VERY diverse watchers

  • Consistency is key

    • Set time for the streams

  • Keeping it positive

    • Thank for negative feedback
    • Ask for clarification if it's not constructive ("what can I do better?")
    • People with situational anxiety, etc. feeling safe

Debugging Our Feelings   ATTACH

  • Working at odds with professional development and depression

  • Cognitive Behavioural Therapy

    • "Feeling Good" by Dr. David Burns
    • parallells with developer life
    • Experiences -> 👩 Thoughts -> Responses
    • "There is nothing either good or bad, but thinking makes it so" (Shakesspeare)
    • We can change how we feel if we change how we think
    • Input -> 💻 Code -> Output

  • Starting a project, getting overwhelmed, distracted, guilty, nervous

    • Similar to application in an incorrect, incomplete state. Not what we wanted yet.
    • We test our output

    • We trust our feelings

      • Emotional reasoning
      • Because I feel something, it must be true
      • Not rational
      • Would be like looking at the app in that state, "I guess I'm done."

  • Feelings should be

    • positive
    • helpful
    • reasonable

    • rational

      • good at rationalizing, working our way back from the feelings, not super helpful

  • Mind reading

    • We respond to what we think they're thinking
    • Leads to impostor syndrome
    • Test the feelings instead. Ask the question, don't guess.

  • All-or-nothing thinking

    • Perfectionism

    • Test

      • Antiperfectionism sheet

        • Task, Effectiveness, Satisfaction
  • Testing helps identify problems, but doesn't fix them
  • Code won't get any better without changes

  • Editor for thoughts

    • Notebook

    • two column technique

      • left hand side: automatic thoughts

        • thought patterns that are causing us to feel that way

          • "I'm overwhelmed" -> thinking, "this is going to be hard"
          • "Guilty" -> thinking, I'm a procrastinator
          • Nervous -> thinking, I'm not going to finish this on time

      • right hand side: rational responses

        • fortune telling

          • we've predicted the future, and are responding as though it's true
          • I can't know this
          • it could also be fun, educational

        • labeling

          • fancy term for name-calling

          • reduces people to one trait

            • "I've always been a procrastinator, I'll always be a procrastinator"
          • I'm not any one thing (I'm procrastinatING)
          • I don't always procrastinate

        • fortune telling

          • takes away our autonomy (it's inevitable)
          • I have control over the outcome
          • there are other options
    • Thoughts can have a "home field advantage" in our heads

  • How does this change when it comes from someone else?

    • It doesn't
    • Still just an experience, just your thoughts
    • "No one can make you feel inferior without your consent" - Eleanor Roosevelt
  • Magnification and Minification
  • Disqualifying the postitive

  • Accepting a compliment

    • pause
    • say thank you

  • Using the two-column technique, have someone to role play them with

    • We don't always extend sympathy to ourselves

  • "Should" is the worst word in the english language

    • Try "I want…"
  • Test your feelings
  • Get your thoughts out of your head
  • Get help
