- Windows, Mac, iOS, and Linux/Unix systems and application programming.
- Delphi/ObjectPascal (A Wizard. And modest too.)
- C (Linux and others) and Objective-C (iOS) (Competent at both.)
- Python (Quite Good. A level or so below master.)
- C++ (After a long hiatus, actively using C++ again, very grateful for Boost libraries!)
- ObjectiveC/Cocoa (Quite good now. I have an app in the app store.)
- Smalltalk/Pharo/Squeak (Love the language, not so in love with the implementations.)
- Embedded Systems, and cross-platform stuff (Windows, Linux, Mac OS X)
