Say you want to move from A to B on a circle. A simple algorithm would be to just go the shortest way from A to B which is well defined if A and B are not antipodal. If they are, you could define to always go against the clock. Now this alg

Morse theory can be used to prove that certain solutions exist/don’t exist. A simple example is: you have an angular robot arm that can turn 360 degrees. Can you come up with a smooth algorithm that moves it from any current position t

This is kind of a trick question because only some will believe it’s a cover story while others believe it’s true. President Trump is actually a good example that everyone could agree on: considering the amount of dirt thrown at him it a cl

In a similar way you could argue that git doesn’t change diff and patch. It just adds a a convenient way to handle patch files. So why open source it? It turns out it’s very useful to have it in software. The same is true for tracking forks
