I just published a short, introduction level article, Speeding up factorial computation by changing the order of multiplications.
This is a story about a small, seemingly innocent code change that speeds up a very simple computation. It is pretty magical and serves as an example of how things are not always what they seem. https://medium.com/concerning-pharo/speeding-up-factorial-computation-by-changing-the-order-of-multiplications-f4da3a5576da#.l3nrk9oax Enjoy, Sven -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org
