Back when I was studying computer science, I was taking the OS exam and the part about Lamport timestamp [0] was optional, but I had studied it because I loved it. When I mentioned it to my professor, he was so happy to hear something new that day that he asked me to describe it in details. This was the year 2001.

Many years later, in 2020, I ended up living in San Francisco, and I had the fortune to meet Leslie Lamport after I sent him a cold email. Lovely and smart guy. This is the text of the first part of that email, just for your curiosity:

Hey Leslie!

You have accompanied me for more than 20 years. I first met your name when studying Lamport timestamps.

And then on, and on, and on, up to a few minutes ago, when I realized that you are also behind the paper and the title of "Byzantine Generals problem", renamed after the "Albanian" generals to the suggestion of Jack Goldberg. Who is he? [1]
