  1. Replying to a process that has died costs nothing and tells you nothing in Erlang. Correct behaviour, and almost always harmless.

    In a pool that lends out browser pages, it quietly cost me a page every time a queued caller gave up waiting. A second bug of the same shape handed the next caller a page from a browser that no longer existed. Monitors, generation stamps, and the gap I now look for everywhere.

  6. Chave FIDO2 sem tela: ela digita o OTP por você

    Você sabia que existe token de segurança que digita o código sozinho? 🔐

    No vídeo, mostro como funciona uma chave FIDO2 sem tela:
    • Não é keylogger: o OTP só é enviado quando você aperta o botão
    • Como não tem tela, ela não mostra o número
    • Ela usa interface de teclado
    • Você posiciona o cursor no campo certo e ela digita o OTP na hora

    Simples e muito seguro! 🤯 Já...

  7. If you were to XOR the Patterson-Gimlin film of 1967 with the Zapruder film of 1963 you would still have to compensate for the high-order two and three dimensional derivatives of typical amateur motion picture film and cameras of the 1960s before you would have a truly high-entropy key stream.

  9. Two-Factor #Authentication (2FA) typically combines a password with a code, whereas Multi-Factor Authentication (MFA) adds more layers, such as biometrics (fingerprint/face) or hardware tokens. Read MFA vs 2FA: What's the difference windowspost.com/2fa-vs-mfa/

    Key Differences Between 2FA and MFA

    Number of Factors: 2FA limits authentication to two layers (e.g., password + OTP), while MFA can incorporate three or more (e.g., password + OTP + fingerprint).

    Security Level: MFA generally provides superior security against sophisticated attacks because it relies on multiple independent factors.

    Complexity & UX: 2FA offers a more streamlined user experience with fewer steps. MFA may cause more user friction due to additional login steps, but it enhances security.

    Flexibility: MFA offers greater flexibility, allowing organizations to adopt adaptive, risk-based authentication, while 2FA is a fixed two-step process

    2FA Example: Entering a password (knowledge) and a code texted to your phone (possession).

    MFA Example: Entering a password, a code from an app, and using a biometric scan (fingerprint or face)
