5. A developer is born
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) • ...
