Tensorflow on edge, or – Building a “smart” security camera with a Raspberry Pi
The amount of time my outdoor cameras are being set off by light, wind, cars, or anything other than a human is insane. Overly cautious security cameras might be a feature, but an annoying one at that...

Twenty Proofs of Euler's Formula: V-E+F=2
Many theorems in mathematics are important enough that they have been proved repeatedly in surprisingly many different ways. Examples of this include the existence of infinitely many prime numbers , the evaluation of \(\zeta(2)\), the fundamental theorem of algebra (polynomials have roots), quadratic reciprocity (a…

Wireless Is a Trap
Over and over again, I’ve seen people fix some wireless-related problem and go “wow, I had no idea how much better this could be!" • Wireless protocols often silently operate in an extremely degraded state that makes them substantially worse than wired equivalents.

H-1B visas and prevailing wage levels: A majority of H-1B employers—including major U.S. tech firms—use the program to pay migrant workers well below market wages
H-1B is a temporary nonimmigrant work visa that allows U.S. employers to hire college-educated migrant workers as well as fashion models from abroad; nearly 500,000 migrant workers are employed in the United States in H-1B status.

Why Figma Wins
Companies are a sequencing of loops. While it’s possible to stumble into an initial core loop that works, the companies that are successful in the long term are the ones that can repeatedly find the next loop. However, this evolution is poorly understood relative to its existential impact on a company’s trajectory…

The Art of the Possible
Ever since the story broke , I’ve had one overriding thought about the Hey.com App Store rejection controversy. It’s a point I’ve already tried to make on a recent episode of ATP and on Twitter . Before WWDC arrives with its own wave of Apple-related news, I’d like to take one more run at it. Here goes.

Cleaning My MacBook After 16800 Hours of Use
I estimated that I had used my mac for approximately 10 hours a day, 5 days a week, 48 weeks a year, for 7 years straight, for a total for whopping 16800 hours. I have written the first versions of most of the software components of my startup using this computer. And all this time, this machine worked without a…

Discovering Dennis Ritchie’s Lost Dissertation
Until recently, across a half-century perhaps fewer than a dozen people had ever had the opportunity to read Dennis Ritchie’s dissertation—the intellectual and biographical fork-in-the-road separating an academic career in computer science from the one at Bell Labs leading to C and Unix. Why?
