“Cryptography started as a military thing in the beginning. But today everybody is using it without even know it. It all started with how we can hide communication from observers.”

“Especially if you’re in tech, understand that if you have one offer you’re probably going to have several offers. It’s not true for every field but tech is hiring and we’re in a good position. Keep going, don’t be afraid to say no or to ask for more time to decide.”
