Polyglot programming and agile development
0 likes377 views
The document discusses the development of multi-platform gaming hardware configuration software that focuses on features such as crowd sourcing, minimal resource usage, and an intuitive GUI across devices. It emphasizes the use of polyglot programming and various tools to overcome operational challenges faced by a small, distributed team, while also highlighting best practices in software development. The case study illustrates the use of lightweight technologies, effective team communication, and the importance of client satisfaction in achieving project goals.
Polyglot programming and agile development
- 1. Polyglot Programming and Agile Development Shashank Teotia Pramod Sadalage ThoughtWorks
- 3. “To create multi-platform gaming hardware configuration software with crowd sourcing and backup abilities with an awesome GUI which looks the same on all supported platforms.” - Client
- 4. “Adding a new platform / device should be trivial.”
- 5. “Of course, don’t forget that the software should have minimal CPU & memory footprint. ! Gamers hate bloatware!”
- 6. “And yes, I have a small team, distributed across 3 continents. They should be busy delivering features, not get caught up in the operational challenges.”
- 7. :)
- 8. OK, this is not a special situation!
- 9. How do you architect?
- 10. Lets look at the world for inspiration

- 12. Carpenter uses many tools to get the job done credit: homespothq.com
- 13. Some time back we could write a system with COBOL
- 14. The world by nature is polyglot
- 15. Have done it earlier Bash/Shell AWK Perl SED etc…
- 16. Neal Ford coined the term in 2006 bit.do/neal4d
- 17. Many new languages on the JVM started the trend
- 18. Java, Jruby, Jython, Clojure, Scala, Groovy, Rhino
- 19. Lets talk of our experience
- 21. “Lets break down the domain!” - Biz people
- 22. “Divide & Integrate!” - informally dressed devs
- 23. Observation
- 24. Think Bounded Context - Eric Evans in Domain Driven Design

- 28. In your search for the right language, you should underrate your current skills. Repeat it.
- 29. Choosing the right language is a competitive edge!
