Problem The square root of 2 can be written as an infinite continued fraction. The infinite continued fraction can be written, ?2 = [1;(2)], (2) indicates that 2 repeats ad infinitum. In a similar way, ?23 = [4;(1,3,1,8)]. It turns out that the sequence o[...]

Problem Consider the fraction, n/d, where n and d are positive integers. If n < d and HCF(n,d)=1, it is called a reduced proper fraction. If we list the set of reduced proper fractions for d <= 8 in ascending order of size, we get: 1/8, 1/7, 1/6, 1/5, 1/4[...]

As part of the WebSharper web server effort, I have been writing an HTTP request parser. Tuning the parser for performance for the common simple case (small, correct HTTP request) has improved performance 8-fold, from 30K to 250K sample requests parsed e[...]

Ages ago when I wrote my previous Eduasync post, I said we'd look at a pipeline model of coroutines. I've decided to skip that, as I do want to cover the topic of this post, and I've got some more "normal" async ideas to write about too. If you want to lo[...]

Fol­low on from my pre­vi­ous test which showed that the ServiceStack.Text JSON seri­al­izer was the top dog in town, I came across a lit­tle library called fastJ­son on code­plex so nat­u­rally I had to test it out and see how it com­pares to the rest! S[...]

Now that FW/1 is available for Clojure, you might have looked at the examples that are in the FW/1 github repo and wondered how to create your own FW/1 application from scratch. Assuming you have Leiningen installed, the easiest way to get sta[...]

Array.prototype.filter seems to be slightly off in IE7-8. It looks like they have added support for standard array functions. That is, it looks like there is a prototype for this in IE7-8 mode in IE9. The problem is that the filter prototype does not work[...]
