  • Stream a USB webcam to HDMI on a Raspberry Pi

    This post exists to collect my notes on displaying a USB webcam on the Raspberry Pi HDMI outputs. This is not the same as streaming the webcam (easy), and this is not for use with the Raspberry Pi camera module. This is specifically for USB UVC webcams.

  • The Real Cause of the Sign In with Apple Zero-Day

    The zero-day bug in Sign In with Apple actually had nothing to do with the OAuth or OpenID Connect part of the Sign In with Apple exchange, and very little to do even with JWTs. Let's take a closer look to see what actually happened.

Hi, I'm Aaron Parecki, Senior Security Architect at Okta, and co-founder of IndieWebCamp. I maintain oauth.net, write and consult about OAuth, and participate in the OAuth Working Group at the IETF. I also help people learn about video production and livestreaming and dabble in product design.

I've been tracking my location since 2008 and I wrote 100 songs in 100 days. I've spoken at conferences around the world about owning your data, OAuth, quantified self, and explained why R is a vowel. Read more.
