Tim Kächele wants to give this talkHat der Markt geregelt?, or: how to build an exchange
While you shouldn't believe all the fairy tales told by the financial industry, such as that a free market can solve everything (affordable housing *cough*), you can believe this: this talk is going to show you how to build an exchange system in ruby.
You may not have to build an exchange on a day to day basis, but the ideas involved can be transfered to other domains and can help you build your own scalable services.
We are going to look at the requirements, the data structures and how to make it reliable.
