So, a bit of fun for the Christmas 2009 issue: solving Sudoku puzzles efficiently. Not if you’re a human, you understand, unless you’re the type of human who likes programming, but from the viewpoint of discussing algorithms for solving via computer. Because, once you’ve programmed how to solve a Sudoku puzzle, it’s pretty easy to then generate puzzles to solve. […]
READ MORENow that we created a rudimentary date library in part 2, it’s time to move back to the cookie code. […]
READ MOREFor the December 2009 issue I turned to the subject of perceptrons and neural networks. This one was very much written for the layman: I’ve never written a neural network in my life. […]
READ MOREAs I said last time, my first library object is going to be a cookie object. […]
READ MOREIn a week when I completed writing my 50th article for PC Plus, it’s kind of fitting to also republish a hoot of an article that I really enjoyed researching. […]
READ MOREFrom comments I received when I wrote my recent article over on my DevExpress ctodx blog, it seems there’s a need for people to understand how to write reusable code in the form of a library in JavaScript, and not fall into those nicely shaped C# potholes along the way. So I thought, let’s have a go. (Update: I’ve made a couple of corrections to point out the files this code appears in.) […]
READ MOREI just published a blog post on my DevExpress ctodx blog about taking some non-idiomatic JavaScript code (actually from a DevExpress CodeCentral example program) and refactoring it to follow JavaScript best practices. […]

photo © 2009 Caitlin Childs | more info (via: Wylio)I was doing a bit of research to try and find some nuggets of information on URL rewriting, especially with regard to GoDaddy’s shared hosting (I run this website (and others) on GoDaddy). I found this article in Google’s cache but the original site (codebeater.com) has gone away (I presume the domain wasn’t renewed). The article was by CodeBeater’s admin. […]
Come October 2009, it was time to write about some algorithm I knew nothing about. And so it was that I delved into two-dimensional bin packing; prompted by a reader question about how to cut cloth efficiently and aiming for the smallest waste possible. […]
READ MORESo, last night I was working on my URL shortening website (jmbk.nl) and the application that generates the short URLs and that redirects existing ones to the actual URLs. And for some unknown reason, the redirections just weren’t working on the actual website. I’d get server errors (even “404-Not Found” server errors) and my redirection ASPX page just didn’t seem to get called. It was, to be polite, a mess. And, because it was late at night and I was tired I was flailing around trying stupid stuff to see what stuck and nothing would. […]
