<p>That's because you've got a concrete understanding of the matter at hand.</p>
<p>But you could make your own exercise, for example: Resize all images in a certain folder sequentially and write them to another folder. After that try to do this concurrent, utilizing the amount of CPUs your computer have. It should speed the process up.</p>
<p>And if you need some feedback, you won't be the first, nor the last to ask some feedback on their github repo.</p>
<p>Document it, and some people actually might have a use case for using a simple CLI tool that does this for you. Allow to set the input and ouput directories using flags for example.</p>
<p>It's no exercise with tests, but I hope it helps :).</p></pre>
