Doug Blaszczak, one of the developers at BB&T, came and spoke about some behind-the-scenes things.
I found the talk very enjoyable, I was actually familiar with some of the material they were discussing due to my time interning at Avast. They talked a lot about cryptography with symmetric and asymmetric encryption and decryption. There were also a couple graduates there who gave advice to us, mainly that learning to review others’ code is a very useful skill.
I would have liked to hear him talk more about accidents or mistakes that happened; I feel he gave the impression their security was perfect and no one ever got in.
