You're describing a sub-group of young Valley-centric developers (and the occasional outspoken charismatic CEO), drawn to Rails because of its prominence in the start-up environment. It's simple numbers: since Rails is arguably the most popular for ambitious SV companies, then sure, it's going to reflect that culture to some extent. But the community runs deeper than that, and the "Matz Is Nice So We Are Nice" world…

I strongly disagree with your statement that Ruby excels and metaprogramming and DSLs. Other languages (Scala, C#, F#, etc) with coherent type systems have demonstrated an ability to define equivalently useful DSLs with the added property of validating correctness of a declarative language at compile time. You mention LINQ as somehow deriving from Ruby -- it doesn't, it derives from set theory, relational algebra, an…

Are normal ruby regex expressions not available in macruby/Rubymotion? If so, why would you bother to use the above code using cocoa regex when the idiomatic ruby version is so much shorter and simpler? The example was supposed to illustrate that some things are easier and more concise in ruby, and thus also presumably in something like Rubymotion. The relevance to your posts is that you are ignoring some very good r…

I really feel like you believe I'm arguing that you shouldn't use Ruby or RubyMotion. I'm not! Ruby has been my go-to language for half a decade now. Heck, I even follow both the MacRuby mailing list and Twitter list. To reiterate, this is the entirety of my argument: > "I don't want to go to the trouble of learning Objective-C" is a weak reason to use RubyMotion, because you'll have to do 99.95% of the same work any…

> RubyMotion is built on top of iOS. You have access to the entire set of public iOS APIs and can also use 3rd-party Objective-C libraries or Gems So this should be compatible with cocos2d right?
