Great Developers Steal

If you take a look at software today, you'll see more smart people building things than there ever have been before. The problem? They're all working in different languages, on different platforms, with different concepts. To take advantage of the full breadth of work that's being done, we need to stay on top of things happening in other communities, and we need to bring good ideas back to Ruby. In this session, we'll look at how to identify great code and concepts, and how to bring them back to our community.

Given at LA RubyConf - 4 Feb 2012.

13. Pierre Menard, Author of the Quixote http://en.wikipedia.org/wiki/File:Donquixote.JPG http://www.coldbacon.com/writing/borges-quixote.html e visible work le by this novelist is easily and brie y enumerated. Impardonable, therefore, are the omissions and additions perpetrated by Madame Henri Bachelier in a fallacious catalogue which a certain daily, whose Protestant tendency is no secret, has had the inconsideration to in ict upon its deplorable readers—though these be few and Calvinist, if not Masonic and circumcised. e true friends of Menard have viewed this catalogue with alarm and even with a certain melancholy. One might say that only yesterday we gathered before his nal monument, amidst the lugubrious cypresses, and already Error tries to tarnish his Memory . . . Decidedly, a brief recti cation is unavoidable. I am aware that it is quite easy to challenge my slight authority. I hope, however, that I shall not be prohibited from mentioning two eminent testimonies. e Baroness de Bacourt (at whose unforgettable vendredis. I had the honor of meeting the lamented poet) has seen t to approve the pages which follow. e Countess de Bagnoregio, one of the most delicate
