The first goal of newbie should be to learn to write clean understandable code. Code golf, where the goal is to write a program in the minimum of characters, might be an interesting intellectual exercise, but it leads to writing cryptic code which is just the opposite of what a beginner should be learning. Besides Dave Thomas code katas which Ryan mentioned. It might be worthwhile to have a look at the old RubyQuiz site http://rubyquiz.com/ -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Github: http://github.com/rubyredrick Twitter: @RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale

I try to write clean yet concise code that solves the problem. It's a great way to start playing with a language that you're not familiar with because, again, the problem statements are *very* simple. It has helped me learn the basics of various languages like the back of my hand. -Jake On Mon, Jun 7, 2010 at 7:45 AM, Rick DeNatale <rick.denatale(a)gmail.com>wrote: > On Mon, Jun 7, 2010 at 7:35 AM, Jacob Mitchell > <jacob.d.mitchell(a)gmail.com> wrote: > > Search for "code golf".

Ruby Quiz is a treasure trove of interesting Ruby problems and solutions. Also, code katas as mentioned previously are a great way to train your "muscle memory" and ingrain proper idioms and techniques. Highly recommended. -- Rein Henrichs http://puppetlabs.com http://reinh.com
