Roll a die and ask students to identify the random variable. Since a die can only take on values of 1, 2, 3, 4, 5, or 6, this is a discrete random variable. Repeat ...

This tool brute-forces the internal seed of Bash's $RANDOM variable after only 2-3 samples, in seconds. After doing so, you are able to predict all future values to ...

You can easily generate a random number at the bash prompt, which you can then use to set said number as a variable. This is useful for everything from writing certain types of scripts to running ...

If you’ve ever tried to learn how to code, you’ll probably know that practical examples make for the best learning experience. While it’s all well and good trying to focus purely on theory, tinkering ...
