6. A developer is born 1. Write crappy PHP “webapp” 2.

   Make every mistake possible, including wiping production data without a backup 3. Learn Java 4. Write better PHP

7. A developer is born <?php // login.php require_once(‘header.php’); // ...

   some php ?> <!-- some HTML --> <?php require_once(footer.php’); ?>

11. Let’s talk languages

12. PHP from the outside • Javas little brother • Death

    by boilerplate

13. JS from the outside • Callback hell • Many solutions

    to one problem • So many small libraries

14. Python from the outside • Getting things done • BIG

    libraries/frameworks

15. Dart from the outside • Modern (built from scratch) •

    Async by default • Small ecosystem

16. Clojure from the outside • Done is better than perfect

    • First “useable” functional language for me • Libraries, not frameworks

17. Learn from each other

18. Learn from Python Readability: if variable is not null: doSomething()

    else: doSomethingElse()

19. Learn from Python Readability: with open(file.txt', 'w') as file: file.write(Hello

    ViennaPHP!')

20. Make common tasks easy: // Constructor ClassName(this.var1, this.var2); Learn from

    Dart

21. Make common tasks easy: // Implicit getters/setters print(obj.var1); //this is

    not a public property Learn from Dart

22. Learn from Clojure Immutability: var1 = 15; var1++;

23. Learn from Clojure Composability: (defn function1 [var1 var2] (str var1

    ″ - ″ var2))

24. Learn from Clojure Composability: (defn function2 [var1] (println (function1 ″DEBUG″

    var1)))

25. Learn from Clojure Syntax doesn’t matter: (defn function2 [var1] (println

    (function [] {:var1 (function2)})))

26. Not only languages • Infrastructure (vagrant / docker) • Architecture

    (Microservices) • Methodology (Agile/Scrum/Kanban) • ...
