              • Portable domains for email: Steve endorses a listener suggestion to purchase your own domain and use third-party services, retaining control if a provider shuts down.
              • Google Topics and monopolies: Steve and Leo debate whether Topics favors large advertisers with greater reach to get user targeting data.
              • Voyager 2 antenna analysis: A listener calculates the antenna beam width mathematically, showing 2 degrees off-axis may not be as remarkable as it sounded.
              • Windows time settings: Steve clarifies the STS issue does not impact end users changing Windows clock settings, it's enterprise server-side.
              • Unix time in TLS handshakes: The hosts discuss why Unix time stamps are sent but not required for TLS, tracing back to early nonce generation.
              • Fake flash drives: Steve warns of a slew of fake high-capacity thumb drives flooding the market, explaining how SpinRite tests detected the flaw.
              • Man-in-the-middle attacks: While agreeing HTTPS helps prevent malicious injection, Steve examines MITM attack practicality, arguing they are difficult for hackers to pull off.
