Max reHIT Workout is an exercise app that guides you through interval workouts. I'll just say I’m proud of how it turned out and if you want an optimal algorithm for exercising, you might like it. Today I have the pleasure of announcing my new app— Max reHIT Workout —on Product Hunt. I won’t pitch the app here.

Sorting is important, but not for the reasons a junior developer might think; almost nobody will need to implement a sorting algorithm, except as an exercise. Senior developers also exercise leadership, although it need not be formal. Is it important to learn about different sorting algorithms, for example?

To build intuition, let’s run through a thought exercise. We then go through a thought exercise: given the observation, what values of the null hypothesis would lead to a decision not to reject, assuming we specify a 5% false positive rate?
