In this talk, we're going to cover the basics of Rubymotion - a sane, Ruby-centric way of developing 100% native iOS apps using Ruby. We'll cover all aspects one has to know in order to start TDDing their own iOS apps from scratch, from installation to deployment with no prior experience on Objective-C required and using the IDE of their choice (unless they really dig XCode).
I wouldn't go so far as Nikos, but I do share some concerns about the exclusivity of this topic. You have to buy a Mac, an iOS device, XCode and RubyMotion (and, presumably, pay an Apple Developer fee) to join the RubyMotion club. I know that plenty of Ruby developers are using Macs and iPhones already, but for the rest this might not be very relevant.
I agree with Nikos in this one. Rubymotion is not open to even experiment with it unless you pay. This means that anyone who learns something new from this talk, will not be able to apply it unless they pay. This means that, even indirectly, this talk is just promoting a commercial product.
Or at least, that's the way I view it :-)
I don't see why "paying" is opposed to "community spirit". The RubyMotion community is pretty strong in open source.
Then again, basic introductions might not fit the spirit of the conference.
But still, you can't even access it without paying. I don't believe it fits with the EuRuKo theme:
Proposals promoting a product, a company or a service will be discarded. - See more at: http://cfp.euruko2013.org/about#rules
as mentioned here: http://cfp.euruko2013.org/about#rules.
It's almost the same as promoting using SQL Server with Ruby because it's faster (or whatever) than the X other SQL system. Related to ruby, but promoting a product or a service.
There's a huge community spirit, with lots of wrappers for Objective-C libraries, as well as a tool chain that's open source. Only part of it is commercial.
Even though RubyMotion is really hyped this period and looks a way more healthier alternative to Objective-C, I don't like the fact that's a commercial software with no community spirit in mind.
