We're in a Golden Age for Amateur Radio
When I started my ham life as KK6VSI in August of 2015, I wish I could have had the information I'm about to lay out here. Of course, most of the equipment didn't yet exist.

Why Skylake CPUs Are Sometimes 50% Slower
I got a call that on newer hardware some performance regression tests have become slower. Not a big deal. Usually it is a bad configuration somewhere in Windows or some BIOS settings were set to no…

Dissecting the Apple M1 GPU, part I
Apple’s latest line of Macs includes their in-house “M1” system-on-chip, featuring a custom GPU. This poses a problem for those of us in the Asahi Linux project who wish to run Linux on our devices, as this custom Apple GPU has neither public documentation nor open source drivers. Some speculate it might descend from…

Inside the Super Nintendo cartridges
One of the remarkable characteristics of the Super Nintendo was the ability for game cartridges (cart) to pack more than instructions and assets into ROM chips. If we open and look at the PCBs, we can find inside things like the CIC copy protection chip, SRAM, and even "enhancement processors".

There oughta be a WiFi Game Boy cartridge
It took a while, but I finally managed to create my own Game Boy cartridge. With WiFi! At this point, it can only demo a simple telnet-style communication and access Wikipedia articles, but I am confident that I will showcase more in the future.
