Today, I would like to remember a pioneer, an internet giant, who passed away on December 26, Larry Roberts. He was the project manager of the ARPA net project, which was the precursor to the internet.
He might not be the most well known person in this field, but he was the one who made some important decisions that up to today determine how the internet behaves.
They successfully implemented ARPAnet, and crucially embraced the then-revolutionary data packet switching to handle traffic.
