I maintain and organize the various Icon / Unicon related pages on Rosetta including creating an introduction/tutorial Icon+Unicon/Intro intended to illustrate some of the essentials of the language. I've created a stub for an offshoot of Unicon called ObjectIcon and an offshoot of Icon called Jcon.

Many of the Icon/Unicon solutions on Rosetta were written by me. There have been steady and some very interesting contributions by a few others (the Icon/Unicon community here is small).

Additionally, I've created a few tasks:

What I like about Rosetta[edit]

  • I've found the ability to look at how problems are approached and solved in different languages is very practical. I've been able to describe things to developers that are based on approaches/techniques in one language and have them find a corresponding technique that they weren't previously aware of (or because I couldn't explain it in terms that they knew).
  • The effort of solving a task in an area you're unfamiliar is a great learning tool that improves your technique.
  • A number of the tasks are mind benders that force you to think beyond the normal/idiomatic ways of solving something. Of course these are frequently different for different languages. For me, Man_or_boy_test was one as well as a number of the functions of function tasks.
  • Then there are other tasks that are just plain mind benders.
  • When a number of people cooperate on a task the results can be really worthwhile.
