The 5 People in your Organization that grow Legacy Code
The presentation by Roberto Cortez discusses the nature of legacy code and the importance of understanding different developer profiles in managing it. He identifies five types of developers—overly energetic engineers, technology enthusiasts, firefighters, smartasses, and interns—each with unique traits and approaches to work. The key to effective collaboration is to recognize and accommodate these differences to enhance team productivity and code quality.

- 3. This presentation isNOT about •Testing •Tools • Refactoring • Or any other thing that you heard before (hopefully)!
- 4. It’s about •Knowing yourself • Knowing others • Dealing with each other differences
- 5. “In historical terms,a legacy is something that is handed down from one period of time to another period of time.” (from Wikipedia) What is Legacy?
- 6.
- 7. What is LegacyCode? • Is it old code? • Is it code no one wants to use? • Or is just badly written code?
- 8. public static StringgetDayOfWeek(String data) { switch (getDOWNum(data)) { case 1: return "Monday"; case 2: return "Tuesday"; case 3: return "Wednesday"; case 4: return "Thursday"; case 5: return "Friday"; case 6: return "Saturday"; case 7: return "Sunday"; } return ("???"); }

- 11. Legacy Code is •Unknown •Scary •Ignored
- 12. Legacy Code iseverywhere • Huge investments in software are to solve business problems, not code problems •Technology evolves way faster than software •New frameworks are released every year
- 13.
- 14. Identify the Source! • Code is written by developers •Tools can help, but they are not enough • Developers are the main contributors!
