Last week, I taught two 2-day classes, which is always insanely intense and really requires an enormous amount of energy. Fortunately, the feedback makes it worth it! Now two weeks of doing some research and consulting. And of course, prepping the menu and trying out some dishes for the holidays!

Awesome research! It's always crazy how many vulnerabilities you can still find by just reading RFCs 🔥
