Hijacking infrared to make a dumb device smart

Linux on a 486SX
Linux on a 486SX A year or two ago, I came into posession of a 1993 Compaq Presario 425. It's a Mac-ish all-in-one with a 14" color (S?)VGA screen capable of 800x600 in full 256-color glory.

Why Apple Will Switch to ARM-Based Macs (2014)
When Steve Jobs announced the transition from PowerPC to Intel processors in 2005, he revealed something that, in hindsight, seemed obvious to everyone who didn’t anticipate the switch: There are two major challenges in this transition.

My Unholy Battle with a Rock64
I’ve got this rock64, which is an aarch64 board comparable to a Raspberry Pi 3 B+ with 4 gigs of ram. For years I’ve wanted to put a distribution on here that doesn’t have a premade image available, mainly because out of all the options on that page I don’t actually like any of them.

Towards a More Open Secure Element Chip
