Re: what do you think about this code?

I think reasonable people can disagree on the details here--I think the names I chose were "good enough" and would be understood by Clojure programmers familiar with the standard data structures and core functions. I should point out that some of these names are conventional in Clojure land, for ex

Hi David, - Stylistically, I found your naming conventions to be too verbose Do you mean you find the method and variable names too long? Here was my first attempt at the diamond kata in Clojure (written in 40 minutes during a commute) (defn print-diamond [letter] (let [alphabet "ABCDEFGHIJ

Mathias, I wrote a short article about building more complex reduce functions here[1]. I wrote it mostly to reinforce my own knowledge. The bottom section will be most relevant to you. Hope it helps, Jarrod [1]: http://jarrodswart.com/articles/clojure-tutorial-reduce-functions On Friday, De

I had started thinking about this problem recently too and also had broken it down to two parts. I was going to create a simple data frame protocol for a) and a ggplot2-inspired library which emits SVG for b). There is prior work for plotting in Incanter (using JFreeChart) and David Liebke also

Wow, I made a lot of mistakes. It should of course reduce into [] (not {}) and then it should be "conj" instead of "assoc". I also made several spelling mistakes... Should probably sleep more I guess :P kl. 11:57:00 UTC+1 fredag 12. desember 2014 skrev Mathias Picker følgende: > > Hi Robin, >
