Practical work: Mentoring activities

Each programmer should at least play around (or get confortable) with multiple programming languages and tools, in order to notice the differences between them and be able to choose the one that fits the best for the task they have.

The list is for juniors or for anyone who did not worked with the said languages / tools. Enjoy!
