Airport Challenge

Personal Learning Objectives

Things to celebrate

good health
catching up with friends after a long time
completing my first individual challenge
being present and really taking in the learnings from each workshop session
the weekly retrospective meeting with the cohort
learning how to plan before implementing code
being curious and dedicating extra time to cementing various concepts
keeping notes of my progress

Emotions

If you don't do the push up, you don't get the muscle.

I had the chance to attend a few pair-programming sessions with some cohort colleagues and apply the independent learning to a live project. The individual challenge which I am currently working on is also quite good as it brings my learning together and I am definitely able to pinpoint the things that have not quite settled or that I may need to practice more.

I've really enjoyed learning about rspec and its functionality. I now understand how to apply the principles of test driven development to a project. I think this enables devs to build clean, organised and methodical lines of code which are easy to read and debug. Although quite challenging, I did enjoy working with user stories and breaking those down into objects and methods that would later then drive the code implementation.

I feel a bit more settled into my learning journey. I appreciate the endless amount of resources available and I feel like I am definitely getting better by the day! I have started t have a more focused approach to studying and make use of my calendar to block time out for different tasks. My intention for the following week is to

Progress and Learnings

General learning

learn to be specific in my google search
make use of available resources
structure my learning
build a decision tree using user stories

Test Driven Development

test-drive a simple program using objects and methods
RSpec use and best practices - Red Green Refactor method
each test should make only one assertion
learn how to create a directory and initialize rspec —init from the command line
local, instance, class, global
ruby class variables
set up a simple project
explain why a complete README is important
initialise and push a git project
give the structure of a User Story
extract a Domain Model from User Stories
define 'Feature Test' and use irb to implement
explain how to use a stack trace to debug errors
debug an error using a stack trace
define RSpec as a testing framework
describe an Object using a specification
set up a Unit Test and implement the simplest code to make it pass
move between Feature and Unit Tests
test that an Object responds to a Message
use RSpec 'predicate' syntax
pass an instance as an argument
set an attribute on an instantiated Object using an @ instance variable
use attr_reader to read an attribute on an instantiated Object
use fail or raise to raise an error
use a 'guard condition
set an initial attribute value using initialize
use the Single Responsibility Principle
explain why doubles are needed to isolate unit tests
use a double to isolate a unit test

Debugging

explain what a bug is
explain a good approach to debugging
follow an effective debugging process to identify a bug
follow an effective debugging process to fix a bug

Empathy

ability to sense other's emotions and imagine what they might be thinking or feeling
validation of others' emotions is so important

Three types of empathy
1. affective - feeling but without the drive to help
2. empathetic concern - internalising emotions and driven to help or respond appropriately
3. cognitive empathy- consciously imagining how someone is feeling without internalising
Tools
- 'Just like me' - Instead of defaulting to create measurements and separations, we attempt to find similarities. Humans are far more similar than different
- Metta Bhavana - may you be happy
- Empathy Active Listening - attention is a commodity; reflect back, ask more questions instead of responding, validate emotions, don't offer unsolicited advice, be present
- Body → Heart → Head (settle body, self compassion, solution oriented)
- Radical Candor
- The 5 Dysfunctions of a Team

Pair programming

learning more as you have to explain the code
idea generation
spread knowledge - new programming language, new development environment, new techniques, short cuts TDD
communication skills
better software through faster feedback
