Destroying x86_64 instruction decoders with differential fuzzing
TL;DR: x86_64 decoding is hard, and the number and variety of implementations available for it makes it uniquely suited to differential fuzzing. We’re open sourcing mishegos, a differential fuzzer for instruction decoders. You can use it to discover discrepancies in your own decoders and analysis tools! In the…

Why Windows 10 Sucks or Everything Wrong with Microsoft Windows
It's funny and equally sad that year 2015 marks the end of the Windows OS for a lot of people.

Building a home NAS on a shoestring budget with the Rock64 SBC (2018)
I’ve gone through many iterations of a Home NAS over the years. It started with an AMD Phenom based system running in a Norco case with about 8 hard SATA hard drives (4 primary, 4 backup via Rsync). The noise and power consumption of that system was overkill for what it was used for, so I sold it and went to a…
