Transmitting data via ultrasound without any special equipment
There are secret messages flying all around you all the time, being transmitted via, most of the time, electromagnetic waves going from antenna to antenna. ELOs “Secret Messages” is a song about posting conspiracy theories via WiFi. But what if you need to get a few bytes from device A to device B (one of the hard…

The current state of TLA⁺ development
The 2025 TLA⁺ Community Event was held last week on May 4th at McMaster University in Hamilton, Ontario, Canada. It was a satellite event to ETAPS 2025, which I also attended, and plan to write about in the near future. I gave a talk somewhat-hucksterishly titled It’s never been easier to write TLA⁺ tooling! which I…

Reverse Engineering All the Raspberry Pis
Earlier this month I covered Jonathan Clark's effort to reverse-engineer the Pi Zero 2 W, and just yesterday, I discovered TubeTime reverse-engineered the Compute Module 5. i reverse-engineered the Raspberry Pi Compute Module 5! check it out at github.com/schlae/cm5-r...

Setting up a trusted, self-signed SSL/TLS certificate authority in Linux
With OpenSSL, it’s pretty easy to generate a simple self-signed TLS certificate . Just run the following command:

Dangerous advice for software engineers
I’m a big fan of “sharp tools”. These are tools that are powerful enough to be hugely helpful or harmful, depending on how they’re used. Most forms of direct…

A bubble that knows it's a bubble
Railway Mania, dot-com, AI. Technology bubbles follow a pattern older than any of them. What's different this time is that everyone knows the script.

Why Fei-Fei Li and Yann LeCun are both betting on "world models"
Gaussian splats, SIMA 2, JEPA and Genie 3 — and why “world model” now means three very different things at once.

If a Meta AI model can read a brain-wide signal, why wouldn't the brain?
In 2023, Meta researchers were able to decode images in thoughts from the brain's magnetic fields. What if that's how the brain coordinates it's own global state?

ESP32 WiFi Superstitions
The ESP32 is a popular microcontroller to use for do-it-yourself home automation, sensors, and a variety of other bits and bobs that you might want to take care of around the house. It’s the successor to the venerable ESP8266 which has found its way into many of our WiFi connected devices (seriously, open up a device…

Hard Mode Rust (2022)
This post is a case study of writing a Rust application using only minimal, artificially constrained API (eg, no dynamic memory allocation). It assumes a fair bit of familiarity with the language.

The stack circuitry of the Intel 8087 floating point chip, reverse-engineered
Early microprocessors were very slow when operating with floating-point numbers. But in 1980, Intel introduced the 8087 floating-point copro...

Packing the world for longest lines of sight
I have a side project to find the longest line of sight on the planet 1 using a novel Total Viewshed algorithm . At a resolution of 3 arc-seconds (~92m x 92m), the planet contains around 4.5 billion elevation samples 2 . Now obviously we don’t need to calculate the visibility between literally every single one of…

Layered Design in Go
This post will describe how I design my programs in Go. I needed this for work, and while I searched for a link, nothing quite fits my coding practices out there. The word “Layered” can pull up some fairly close descriptions, but I want to lay out what I do.

The Math Behind GANs (2020)
Generative Adversarial Networks refer to a family of generative models that seek to discover the underlying distribution behind a certain data generating process. This distribution is discovered through an adversarial competition between a generator and a discriminator. As we saw in an earlier introductory post on…
