"hi I am Greg, this is wrong, everything I say is public information and *not* under NDA" - @gregkh on stage of the #GoogleAndroidBootcamp
I think this is the most time-standing IT book that I own. It was published in 1999 and I still check it from time to time.
E.g. when collaborating with hpa on arch/x86/realmode
, this book was my main reference in addition to ELF specification.
It is also as prose very nice reading with cool stories embedded!
A recent #Amiga demo "Backslide to Arcanum" by Cosmic Orbs included a mind-blowing fullscreen 50Hz rotozoom effect on Amiga 500. Having created a rotozoomer on A500 back in the day I knew exactly how incredibly hard it is to make such routine run fast. The effect has now been dissected and there's also author's writeup.

Ok, the fact that the "AI" (NPU) chip controller inside Intel's new Meteor Lake CPUs uses SPARC instruction set (from 1990?) was not on my bingo cards for this year. https://chipsandcheese.com/2024/04/22/intel-meteor-lakes-npu/
