- First degree was BSc hons Biochemistry from University of Surrey, I went on to specialize in xenobiotic metabolism (at first drugs, then industrial chemicals and pesticides).  I later studied for a computer science degree with the Open University (BSc hons 2:1 but completed insufficient specific modules to be a named degree), course included some smalltalk but mainly java. Subsequently I dabbled a bit with C++, perl python, and even lisp, but got hooked on ruby, particulary ruby-processing. OS experience Windows-98 up to Windows-XP and mainly linux since 2004 (tried gentoo, fedora, even pardus) now using exclusively Archlinux and Mint (Debian). Since November 2012 I have been sole developer/maintainer of [ruby-processing][ruby-processing] (_did update for processing-2.0_), and I have since developed JRubyArt and propane (_for processing-3.0+_) and ensured that jruby-9.2.0.0 (with support from jruby group) continued to work with ruby-processing, and its descendants.

  Personally I can't understand why processing group spawned p5*js (javascript is just horrible), but I learned sufficient to develop atom packages [atom-k9][atom-k9] and [language-jruby-art][language] for JRubyArt / propane.

-ASFAIK there isn't a book on ruby-processing, JRubyArt, or propane perhaps (I thinking about writing one). There's plenty of books on processing, and some where code has been ported to ruby. If you are new to ruby there's quite a lot available (_including on line_), but if you are coming from java or processing you can learn a lot just running the examples and reading the code (__Rails__ is a terrible place to start to learn ruby).

 If you're just learning to code for the first time, [learning processing with ruby][lruby] includes most of the examples from Daniel Shiffman's [Learning Processing][lprocessing], an introductory textbook (move `size` to `settings` to port to JRubyArt). Or there is the more up to date [The Nature of Code][ncode] (_more advanced topics_) also by Daniel Shiffman, and this case majority of the examples have been [ported to ruby][ncode_ruby]. Even more processing books are listed at [processing.org]. If you want get serious with ruby there's Sandi Metz's [Practical Object-Oriented Design][poodr] which should help guide you to write decent ruby code. If you fancy doing a bit of re-factoring get [Sandis latest book][99] because there are plenty of opportunities to re-factor both ruby-processing project code, and the example sketches.
 
 Note: Nature of Code also available in [Japanese][japanese], it would cool to annotate some of the ruby examples?
