Engineering & Code explores the full stack of modern tech—from bits and transistors to cloud fleets and formal proofs. Here you’ll find clear, rigorous walk-throughs of software design, embedded hardware, security architecture, and the physics that underpins them, always paired with code, schematics, and reasoning you can put to work.
When President Trump signed the GENIUS Act on July 18, 2025, he didn’t just regulate stablecoins—he legitimized an entire technology stack that will become core infrastructure for defense and intelligence agencies. By requiring full liquid reserves and exempting compliant stablecoins from securities regulations, the Act transforms what was once speculative technology into government-grade payment and […] read more
A Chinese research team just pushed quantum computing one step closer to breaking the encryption that secures your bank account. The security that protects your credit card, banking, and private messages relies on a simple mathematical bet: it would take classical computers longer than the age of the universe to crack a 2048-bit RSA key. […] read more
Communication is the most important skill to sell your ideas. If the last decade has taught us anything, it’s that ideas don’t win because they’re right—they win because someone makes them impossible to ignore. The best communicators I've seen combine advanced graphics with deep understanding of a subject. I start simple and show how to get started in web graphics. read more
(warning: I’m not trying here to explain something to folks outside computer science, but more summarize something awesome I’m learning that is changing how I write code) As software systems grow increasingly complex and automated, ensuring correctness becomes a monumental challenge. In a future of automatically generated code, certainty is both elusive and critical. Enter […] read more
I manage my own webserver via docker and have a wordpress blog for each of my kids (eg lauren.theboohers.org) Yea dad! Well, I noticed that loading my son’s blog (david.theboohers.org) would occasionally redirect. I’m sharing how I dealt with this so you might save some time and pain. What is the problem? Over the past […] read more
You can’t build anything big and important without a solid foundation. In security, hardware acts as that unyielding foundation, the basis for all other defenses. While fancy encryption and zero-trust principles can safeguard data in an environment where software is inherently untrusted, they ultimately rely on hardware’s immutable security properties. Companies are partnering with cloud […] read more
I’m going dive into the theory of laser alignment, show the math and the jigs I built to put that math into practice. This post is for someone who wants the “why” behind a lot of the online material on laser cutters. If you just want some practical tips on how to better align your […] read more
Note: these results are still new and will need to be replicated and further studied by the scientific community. This whole thing may be nonsense, but I did some thinking on the impact if it’s true. Researchers from Korea University have synthesized a superconductor that works at ambient pressure and mild oven-like temperatures (like 260 […] read more
If you are like us, you get too many mice and keyboards lying around. With 5 or six devices, and an equal number of receivers you can just plug stuff in to find what matches. That assumes the peripherals are working and haven’t been lost. Can we interrogate the usb receivers and discover their associated […] read more
I recently encountered an issue when generating a grid of holes for workbench. I had recently planed down an old workbench from our house in New Jersey. I was planning on 20 mm holes spaced in a grid with 96mm spacing to match the festool MFT table. I’m hoping to use the available array of […] read more
