This writer never uses AI.

The purpose of AI is to produce minimally viable text.

My purpose is to produce text that expands your mental foundations to be more skilled and more compassionate. Tech book, fiction, doesn't matter, that's the goal.

One of my nice friends at Hurricane Electric gave me a dead 100G-LR4 optic to tear apart for your entertainment, so for the sake of your entertainment, lets dig into it! 🧵

Xerox scanners/photocopiers randomly alter numbers in scanned documents Please see the „condensed time line“ section (the next one) for a time line of how the Xerox saga unfolded. It for example depicts that I did not push the thing to the public right away, but gave Xerox a lot of time before I did so. <iframe width="700" height="394" src="https://www.youtube.com/embed/c0O6UXrOZJo" frameborder="0" allowfullscreen></iframe>
