Hats off to Malan, excellent lecturer, i love the cs50 lectures, wanted to do this one just as a refresher, its excellent. It took me years to learn all these fundamentals that finally made the various exploits click. You need a bit of backend, frontend, databases, linux/systems programming to understand how these things work and that takes a long time to build. Malan explains it so elegantly in just a few hours, and you dont even need the background!

This lecture deserves more positive comments. So here is mine: tremendous capability of explaining a complex topic. Not to mention the energy he puts into teaching. This is a must watch video on the topic.

This guy can teach nuclear physics to a 3-year old 😇

I am hooked and binge watching your videos. I wish we had these videos when I was going to school. But nevertheless I am happy for my son and all who can watch and learn. Thanks to team CS50 & Prof. Malan.

David could teach Japanese to a chimpanzee and it would be fluent in the language by week four.
