Why do so many of us get nervous when public speaking? Communication expert Lawrence Bernstein says the key to dealing with the pressure is as simple as having a casual chat. He introduces the "coffee shop test" as a way to help you overcome nerves, connect with your audience and deliver a message that truly resonates. After the talk, Modupe explains a similar approach in academia called the "Grandma test," and how public speaking can be as simple as a conversation with grandma.

In today's episode, we're going to explore the fascinating topic of operating systems authentications. We all use it but how many of us wondered how the behind the curtains machinery work. We'll be focusing on Windows, Linux/Unix, and Mac OS. We'll discuss how hashes are used in authentication, the concept of salt in passwords, rainbow table attacks and their countermeasures, the benefits of password-less authentication using hardware keys, password cracking, the shadow file in Unix/Linux, and the mechanics of how each OS protects passwords and how attackers try to circumvent these protections.
