Thinking in Data
Recorded at:

by Stuart Sierra on Aug 30, 2012 |

Summary
Stuart Sierra discusses using a data-oriented programming approach in order to create programs that are easier to write and test. The session is accompanied with Clojure code samples.

Bio

Stuart Sierra is a member of the Clojure/core team at Relevance, Inc., and the co-author (with Luke VanderHart) of Practical Clojure (Apress. 2010).

Clojure/West is a new conference bringing the Clojure community together to discuss techniques, tools, and the state of the Clojure ecosystem March 16-17th for three tracks of sessions. Prior to the conference, register for three days of training by the Clojure experts.

A bit backward by Serge Bureau

We are in fact promoting to go back programming like in the sixties.
Yes there is a percentage of applications tha are data centric, but it is far from the majoriry.
Loosing the object orientation is too high a loss.

Amusing to promote "visual abstraction" , since abstraction is very low on data centric programming, we see the tree but not the forest.

The techniques presented are very well thought and appreciated the presentation, but I will stick to something like Scala that gives me data centric while also giving me the most important, object orientation. So yes I am an object.

It's all about representations by Henrique Rangel

Whether it's an object, a map or even an array, they're all representations and abstractions. Should all be maps? I don't think so, but it depends of course :)

great talk but these ideas are not new by Steven Sagaert

great talk but data oriented programming is basically functional programming and his state threading pattern= the state monad from Haskell and generative testing=quickcheck from Haskell & Erlang.

Re: great talk but these ideas are not new by Paul Anders

to quote alan kay loosely: Computer science turned into pop culture. And to apply ideas from computer science, research , functional programming into the corporate world is an goal worthy to pursue. Not always easy but if you can do it, it can be useful.

Re: great talk but these ideas are not new by p callaghan

Agree, but sometimes these things need to repeated a few time for people to start to appreciate the points. Would have been nice to have a few references to earlier work though. Also see this from a recent PragPub magazine pragprog.com/magazines/2012-08/thinking-functio...

It's all about connascence by Rich Morin

Using maps reduces a strong form of connascence (position) into a weaker one (name). Stuart's other suggestions can also be examined in terms of connascence.

See Connascence (computer programming) in Wikipedia and Jim Weirich's Grand Unified Theory of Software Design talk.
