OpenCV Tutorial demonstrates how a Python program is built to measure the distance of a hand using a single webcam
Apart from the information on how to use these Python libraries (hand recognition and tracking), it’s a very interesting exercise which shows how you build out any program piece by piece, by testing the logic at each step. This is, of course, not possible if you don’t have open source code to examine and re-use.
I love how the logic is unpacked at each stage, and it is the approach most programmers will use to simplify what can become complex as it progresses to completion. You test each stage before starting a new one, and this is where you’d notice the X measurement is not sufficient to provide accurate results, and why the diagonal measurement is more accurate. Then testing whether it is a linear relationship or not, and so you keep building up the following stages.
Although this was for hand recognition and distance interpretation, the type of approach could be followed for face tracking or anything else.

We have to say, [Murtaza]’s example game in his latest video isn’t very exciting. However, the OpenCV technique he uses to track a hand and determine its distance from a single camera i…

How different programming languages read and write data: C, C++, Java, Groovy, Lua, and Python
In his article How different programming languages do the same thing, Jim Hall demonstrates how 6 different languages accomplish the same exact task with different syntax. The lesson is that programming languages tend to have many similarities, and once you know one programming language, you can learn another by figuring its syntax and structure.
In the same spirit, Jim's article compares how different programming languages read and write data. Whether that data comes from a configuration file or from a file a user creates, processing data on a storage device is a common task for coders.
Every programming language has a unique way of accomplishing a task; that's why there are so many languages to choose from. You can and should choose the language that works best for you. But once you understand the basic constructs of programming, you can also feel free to try out different languages, without fear of not knowing how to accomplish basic tasks. More often than not, the pathways to a goal are similar, so they're easy to learn as long as you keep the basic concepts in mind.
