A historical collection of our writing.
In the last two Tech Tuesdays, I introduced Finite State Machines (FSM) and showed examples of both their usefulness and their limitation. Just as a reminder, we study computer science theory to get a handle on two fundamental questions: what can be computed at all (computability)? And, how hard is […] Read more (opens Continuations in a new tab)
We owe many of the innovations that we use every day — from our favorite longstanding websites to the latest mobile applications — to the existence of underlying highly technical protocols.
