Short one this week because I'm way behind on book and conference prep.

Pooch from Repkord dropped by my studio while he was in St. Louis, and asked a simple question: Can a 3D printer's heatbed act as an antenna?

The trigonometric Fourier series is a beautiful mathematical theory that shows how to decompose a periodic function into an infinite sum of sinusoids.

One of the things I like best about blogs is that posts stick around (or at least they should).

A decade ago, I settled on iozone for disk benchmarking on all my systems.

Early in my career, a manager at one of the big firms where I worked made a request so absurd it remains etched in my memory.

Ok, so you have something with a battery, and you want it to run for a long time. First off, it helps to measure power draw in current and charge in well, charge. It is tempting to convert everything into power and energy, but don't. Even if you don't use any, most chips will use a few to generate internal voltages. This is the "typical" current draw of an AVR32DD32 microcontroller over volta

I’m calling it now, the adoption of AI agents into software development will be one of the most costly mistakes in the field’s history.

The difference between a circular function and a hyperbolic function is a rotation or two. For example, cosh(z) = cos(iz). You can read that as saying that to find the hyperbolic cosine of z, first you rotate z a quarter turn to the left (i.e. multiply by i) and then take the cosine. For another example, […] Circular and hyperbolic functions differ by rotations first appeared on John D. Cook.

Markov numbers are integer solutions to x² + y² + z² = 3xyz. The Wikipedia article on Markov numbers mentions that Don Zagier studied Markov numbers by looking the approximating equation x² + y² + z² = 3xyz + 4/9 which is equivalent to f(x) + f(y) = f(z) where f(t) is defined as arccosh(3t/2).

TL;DR: Instead of labouriously computing \(c = \sqrt{a^2 + b^2}\), we can mentally calculate using the alpha-max plus beta-min algorithm, by estimating \[\hat{c} = \mathrm{max}\left(a, 0.9a + 0.5b \right)\] and this will be very close to the actual \(c\). This is useful for adding up sources of variance, or figuring out radiuses, or other such things. (Continue reading the full artic
