rubyでDCIを実装するなら移譲でいいんじゃないか？
以下の記事を読むと、DCIはRubyでは遅いという指摘があったので、移譲で 実装すればいいと思ったので、下記記事のサンプルコードをもとに、 send/method_missing, forwardable, delegateを使ったサンプルを書いて みました。 “DCI”in Ruby is completely broken ※ 上記記事では移譲を使ったアプローチにも言及しているし、改善するには 頑張らないといけないという程度の話と認識しました。 ■ ベンチマークの結果（ruby 1.9.3p194） without dci 3024223.4 (±1.7%) i/s - 15139474 in 5.007655s with dci 768491.0 (±6.6%) i/s - 3833440 in 5.011732s with dci(send) 1586461.1 (±2.1%) i
artima - The DCI Architecture: A New Vision of Object-Oriented Programming
Object-oriented programming was supposed to unify the perspectives of the programmer and the end user in computer code: a boon both to usability and program comprehension. While objects capture structure well, they fail to capture system action. DCI is a vision to capture the end user cognitive model of roles and interactions between them. Objects are principally about people and their mental mode
Data, context and interaction - Wikipedia
Data, context, and interaction (DCI) is a paradigm used in computer software to program systems of communicating objects. Its goals are: To improve the readability of object-oriented code by giving system behavior first-class status; To cleanly separate code for rapidly changing system behavior (what a system does) versus slowly changing domain knowledge (what a system is), instead of combining bo
"DCI" in Ruby is completely broken • Tony Arcieri
January 2, 2013 “DCI” in Ruby is completely broken Rubyists are people who generally value elegance over performance. “CPU time is cheaper than developer time!” is a mantra Rubyists have repeated for years. Performance has almost always taken a second seat to producing beautiful code, to the point that Rubyists chose what used to be (but is no longer) the slowest programming language on earth in o
21: Data, Context and Interaction
Ben Orenstein is joined by Jim Gay, author of Clean Ruby, and Joe Ferris, CTO of thoughtbot, in the episode recorded at RubyConf 2012. Ben, Joe, and Jim discuss Data, Context and Interaction (DCI), what it is, whether it is at odds with Object-Oriented Programming, how it can be applied to your applications, and much more.
