Because it’s Friday: I hate pennies

October 1, 2010
By

I was brought up in Australia, where we got rid of 1¢ and 2¢ coins in my childhood. Nobody missed them, at least as I recall. I certainly didn't: they were useless, even at the age when I might by lollies (candy) for 2¢ apiece. But then again, I'd never buy one, and with the new changes if I...

Fibonacci 1-liners

October 1, 2010
By

The other day, as an excuse to play around with custom iterators, I created some completely over-engineered code to calculate the Fibonacci sequences. But surely such a simple function can be implemented in fewer than my 15 lines? (Rick Wicklin, who writes the SAS blog The Do Loop, thinks so too.) We could use such a function to more...

Mandelbrot Set, evolved

The Mandelbrot Set is perhaps the most famous fractal of all time. It's simple in its definition: iterate the complex equation zn+1 = zn2 + c (starting with z0 = 0) for various values of c, and if doesn't go to infinity then c is part of the Mandelbrot Set. The result, however, is amazingly complex. Thinking of c...

NewTwitter design based on a Golden Spiral

I finally got the new version of Twitter yesterday, and it looks great. And that's no accident: according to the designer, the layout of the new Twitter interface is based on the Golden Spiral: You can describe the Golden Spiral by laying consecutive squares in a spiral fashion, each square being smaller than the last by a factor of...

This video brings flashbacks for my days as a statistics consultant to a medical school. Some days we just weren't speaking the same language... (With thanks to reader MK for the tip: "It's funny because it is true...".)

Guidelines for efficient R programming

September 22, 2010
By

R is designed to make it easy to clearly express statistical ideas in code, but when it come to writing code that runs as fast as possible, there are a few tips, tricks and caveats to be aware of. As part of the BioConductor conference this past summer, Martin Morgan prepared a tutorial on efficient R programming. (Patrick Abouyen...
