The familiar five volts standard from back in the TTL days always struck me as odd. Back when I was just a poor kid trying to cobble together my first circuits from the Forrest Mims Engineer’s Notebook, TTL was always a problem. That narrow 4.75 V to 5.25 V spec for Vcc was hard to […]
Supercon is just around the corner, and we’re absolutely thrilled to announce the second half of our slate! Supercon will sell out so get your tickets now before it’s too late. If you’re on the fence, we hope this pushes you over the line. And if it doesn’t, stay tuned — we’ve still got to […]
It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to Hi-Fi audio. Now it’s time to return with part two of our look at distortion, and attempt some real-world distortion measurements on the bench. Last time, we examined distortion from a theoretical perspective, as […]
Elliot Williams and Al Williams got together to share their favorite hacks of the week with you. If you listen in, you’ll hear exciting news about the upcoming SuperCon and the rare occurrence of Al winning the What’s That Sound game. For hacks, the guys talk about the IEEE’s take on the “best” programming languages […]
This week a reader sent me a story about a CVE in Notepad++, and something isn’t quite right. The story is a DLL hijack, a technique where a legitimate program’s Dynamic Link Library (DLL) is replaced with a malicious DLL. This can be used for very stealthy persistence as well as escalation of privilege. This […]
Imagine you have a natural stream running through a low-lying area on your farm. It’s a great source of fresh water, only you really need it to irrigate some crops sitting at a higher elevation. The area is quite remote from fixed utilities, complicating the problem. Your first thought might be to grab a commercial […]
This week Jonathan talks with Brandon and TC about Veilid, the peer-to-peer networking framework that takes inspiration from Tor, and VeilidChat, the encrypted messenger built on top of it. What was the inspiration? How does it work, and what can you do with it? Listen to find out!

These days, we take it for granted that you can connect a cheap piece of hardware to a microcontroller and have an amazing debugging experience. Stop the program. Examine memory and registers. You can see and usually change anything. There are only a handful of ways this is done on modern CPUs, and they all […]
