A 10-Minute Introduction to Multipole Methods, with MATLAB Code. A 10-Minute Introduction to Multipole Methods, with MATLAB Code. As someone who's more of a mathematics fan than a practitioner, multipole methods at first seemed like straight-up black magic to me. Problems that canonically have an $O(n 2)$ complexity being solved in $O(nlog(n) $ or $O(n)$ time seemed.like a lie. But I was able to get a grip on the simplest case, and now, I'm a believer. Summation symbol and algebra. To solve the entire pr...

Tutorial: using cURLcpp to Create a C Web Reader in Ubuntu. In this article, we're going to create a C application with cURLcpp. That reads a webpage and prints the HTML source to stdout. I wanted to try cURLcpp as opposed to the tried and usually true cURLpp, mostly for fun. Read more about Tutorial: using cURLcpp to Create a C Web Reader in Ubuntu.

Debugging Custom C Types in Codeblocks (Code: Blocks). Debugging Custom C Types in Codeblocks (Code: Blocks). When I develop C on Linux, and I'm not in a purist/makefile/command-line mood, I like to use Code: Blocks. It doesn't quite have the feature set that Eclipse does, but Eclipse always feels a bit cumbersome to me. On the flipside, Code: Blocks seems much more lightweight. Nothing overly complicated there. Now let's debug the program, and 'watch' the array. Debugging in Code: Blocks. Stl-views-1&#4...

Alpha-Surf, my half-baked Google Chrome Extension. Alpha-Surf, my half-baked Google Chrome Extension. A while ago, I hurt my wrist in a way that made it painful to use the mouse. This obviously put quite a hindrance on my ability to effectively surf the internets. I was able to get around on most websites pretty easily with keyboard shortcuts, but I found that tabbing through links was still pretty tedious and time consuming. Based on the first letter of the text in the link. Manifest version": 2, "name"...
