We want to know how many iterations the function could potentially execute at it’s max. This …
In order to make changes to code files from our pipeline, sometimes we have to create a bash script. A pipeline can use a bash script to edit files before the files are compiled into an application. I used an Azure DevOps pipeline in this example but the bash script task can be applied to …

Everything your computer does can be translated into bits. Bitwise operators perform operations on binary numerals to manipulate individual bits. This can be quite useful for programmatic functions such as Bluetooth where the individual bits in a package’s header are important or controlling different functions on a chip is a requirement. These operations can also …
