The Joys of Unix Keyboards
A decade or so ago while helping a friends father clean out an old building, we came across an ancient Sun Microsystems server. We found it curious. Everything about it was different from what we were used to. The command line was black text on a white background, the connectors strange and foreign, and the keyboard…

Using a tiny HC32L110 ARM chip
A while ago, Hackaday highlighted a new chip, the HC32L110. This chip was one of the many ARM-based microcontrollers that sprung up in China, but this one was remarkable because its diminuitive size: it came in an 16-pin WCSP package of a miniscule 1.6x1.4mm. Aside from that, it seems to be a chip that is somewhat…

Hiding your data in plain sight: USB hardware hiding
This article will describe the possibility of hiding data in any kind of USB hardware. Even though USB data carriers come in various sizes and forms, which already sometimes makes them hard to recognize, this approach could even make it worse. Any USB device could be a data carrier and thus from a forensics point of…

“It's done in hardware so it's cheap” (2012)
This is one of these things that look very obvious to me, to the point where it seems not worth discussing. However, I've heard the idea that "hardware magically makes things cheap" from several PhDs over the years. So apparently, if you aren't into hardware, it's not obvious at all.

SSD as Long Term Storage Testing
2022 September 10 What is the best media for long term storage is a question that I read frequently from online forums. First and foremost, as far as I’m aware there is no real “set it and forget it” long term storage. In this digital age, data needs to be validated regularly and cycled to a new media every 5-10 years…
