engineering notes from the signal domain
Your camera writes forty fields about itself and none about you. What gets signed today, what a byline would actually take, and why the one field that settles every dispute has shipped empty since 1988.
Every messenger that calls itself end-to-end encrypted has more than two ends.
Here's the full count, platform by platform, gloves off. And what 2 actually looks like.
* No cryptography was harmed in the making of this compromise. Except Intel's. Kind of.
That one time. But not really.
On authentication, accelerometers, and the math everyone ignores. 658 people died and the system couldn't cope because it stored identity as a memorized string.
Flicker in automotive lighting is confusing robot vision systems, and costing millions to work around. The fix costs $6-54 per vehicle. Nobody's implementing it.
Mapping wave patterns in a metal cavity at 2 ish GHz using eggs as test loads. Inside-out cooking, magnetron duty cycles, and why geometry matters more than theory.
Don't ask Bard for directions.
Why amber and orange feel more distinct than cyan and blue. How your eyes sample the warm spectrum more densely than cool. And why display technology still mostly ignores how human colour perception actually works.
On promised lands, navigation mechanics, and the difference between belief and implementation. Wrestling with understanding versus imagining future rewards. The kingdom is here
—whether it's heaven or hell depends on what you build.
Twenty years in telecom before I actually looked at how SIM authentication works. Found four catastrophic flaws in thirty minutes. The architecture isn't broken by accident—it serves too many interests to fix.
Absurdist bureaucratic nonsense originally generated for cryptographic testing. Sometimes the test data is more entertaining than the algorithm.
Combining elevation data, hydrography, land classification, and transport networks into a single high-resolution map using Rust. From LINZ datasets to final composite.
What took Sega's artists years to create in 64 colors and 4MB now takes thirteen Midjourney prompts over breakfast. The constraint isn't capability—it's knowing what to ask for.
On property ownership, cryptographic truth, and genuinely not knowing what the IRS wants me to report.
