C++11/14 – Lambdas

## C++11/14 – Lambdas

Introduction “Lambda” expressions are a part of an effort in C++11 to introduce more “functional programming“-like features to the C++ language. Normally when we write shared code that needs to take advantage of slightly different, specific behavior we would do one of a few things: Inheritance – Define the common functionality in the base class, and implement the specific behavior in the derived class as a virtual function. Callback function – Write the common functionality, and invoke a callback (c-style…

Geometric Transformation Fitting

## Geometric Transformation Fitting

Problem Definition Given the following equation and an arbitrary number of point correspondence determine scale, rotation, and translation. (1)   Introduction Imagine you are sitting at home doing a bit of programming. Suddenly a rogue mathematician kicks in your door, and presents you with two sets of point data (spanning millions of points), demanding that you find a sufficient relative transformation between them. He assures you that: The points are linearly independent. You will have beforehand the correspondence of points…

Connecting Android Device to Winsock via Bluetooth

## Connecting Android Device to Winsock via Bluetooth

I am writing this tutorial in order to help others who find themselves in a similar position to my own. I recently had the task of connecting an android 4.3 device to a windows machine relying entirely on winsock. The more I researched the issue, the more I realized that there simply aren’t many good resources when it comes to this very specific problem I was attempting to solve. As a result, I am going to attempt to outline here the…

Move Construction Explained

## Move Construction Explained

C++11 brought us a whole host of useful features, and expansions on STL. One such feature is the introduction of “move semantics” to the C++ language. Put simply, move operations are the ability to “move” a resource (memory, file handle, etc.) instead of copying it. Imagine you are back in college, and missed an important class. To avoid falling behind, you ask a friend if you can copy their notes. As it turns out, your friend took the course last semester and…
