I'm trying to create some helper functions that will allow me to convert from one unit of measurement to another. I eventually will need to be able to do speeds and temperatures as well, but so far, I've only implemented lengths. I'm not using C++11 for this solution. Here are my structs. My str...

I'm trying to figure out if there's a way I can simplify this code which is used to generate a robots.txt file with numerous rules. Different files/folders are separated in separate arrays because they're applied differently but in some cases they are applied the same. In these cases, rather th...

I just started a new project which reads in a video file and splits it up into frames. I started by just throwing everything in the GUI, but decided I wanted to make this a more well designed program, backed with unit tests.

Just over half way through in K&R, came across an exercise to convert from postfix ("reverse-Polish") notation to infix (standard) notation. Basically I'm posting here to see if there is anything excessive in my code, or any way to reduce the amount of storage it takes up. It runs extremely fas...

Problem Statement: T1, T2 to Tn threads prints numbers up to N such that each threads prints number in circular sequential fashion. T1 prints 1, T2 prints 2, T3 prints 3 and T1 prints 4 again following strict ordering. This implementation would allow us to control any number of threads to do sequ...

I have 2 types of means: incremental: mean = cntr*mean + val; mean /= ++cntr; typical: mean = sum(elements)/elements.size(); Which one is better to use and in which cases?

In my real life example I am at a layout stage and before I actually move any further I would like to review my current approach. I am still learning about UI, XAML on WPF technology and I guess I haven't gotten my head around all the possible approaches yet. I have build this very simple SSCCE...

The more I consider object oriented JavaScript the more I am confused. There are so many different ways and concepts and I simply do not know any longer what fits best for my purposes. I like the constructor pattern but I have the feeling that I've mixed different concepts: Subclass.prototype =...
