Coding for Non-Coders workshop

This deck is the (very) skinny outline of what's covered in my all-day workshop, Coding for Non-Coders. This workshop is based on my online video course hosted at the Ministry of Testing: https://ministryoftesting.com/dojo/series/coding-for-non-coders-jim-holmes

You can find the code for this workshop at my GitHub repository: https://github.com/jimholmes/CodingWorkshop

6. Hello World
7. What’s Writing Code Look Like to You?
8. Writing Code is…
9. Today’s Goals • Understand why coding is valuable for you • Get comfortable with writing simple code • Learn to write code and use code tools • Learn how to collaborate with developers • Gain confidence in working with code
10. Today’s Blocks 1. How Code Works 2.Libraries, Code, Writing Tests! 3.More Tests, Lean Coffee (YOU choose what we cover!) 4.Code Katas
11. This Course Will NOT •Make you a professional software engineer •Teach you in-depth coding concepts •Teach you how to use source control •Make you a master with an IDE
12. This Course WILL •Give you a starting point for good conversations •Get you familiar with fundamentals of writing code •Get you comfortable enough to continue learning
13. Block I: How Code Works
14. Exercise: HelloWorld
15. How Code Executes

19. Coding for Non-Coders What Humans Need Please do what I mean and not what I typed
20. Coding for Non-Coders Interpreted Code Source Code File Interpreter
21. Coding for Non-Coders Compiled Code Source Code File Compiler Executable
22. Coding for Non-Coders Just-In-Time Code Source Code File Intermediate Compiler Intermediate File JIT Compiler
23. • CPUs only speak binary • Each type of CPU is unique • Text => Executable varies by language platform • Execution models vary (Interpreted, JIT, compiled) Coding for Non-Coders Recap
24. • Procedural == Straight line of execution • C, Pascal, Cobol • Object Oriented == Everything is a Thing • Java, Python, C++, .NET, Java, many others • Functional == Highly structured • Lisp, Haskell, F#, many others Coding for Non-Coders General Types of Programming
25. • camelCasing • Common in Java • PascalCasing • .NET and others • behavior_driven_development • Ruby, BDD enthusiasts Coding for Non-Coders Naming Conventions
26. • Naming • Recursion • Off-by-one errors Coding for Non-Coders Two Hardest Things in Programming
27. Follow your team’s conventions
28. • Classes == A thing • Methods == Behaviors • Properties == Attributes/Characteristics • Inheritance == Share common traits • Encapsulation == Hide information Coding for Non-Coders A Bit on OOP
