Very interesting article at the IEEE ACM by David Chisnall.
In the wake of the recent Meltdown and Spectre vulnerabilities, it's worth spending some time looking at root causes. Both of these vulnerabilities involved processors speculatively executing instructions past some kind of access check and allowing the attacker to observe the results via a side channel. The features that led to these vulnerabilities, along with several others, were added to let C programmers continue to believe they were programming in a low-level language, when this hasn't been the case for decades.

I remember looking at some assembler language once. In the 1980's. I think it was 68000, but memory grows weaker. But I was astonished at how much you could do with the macro system. The macro system was a programming language.
Interesting to study. But I didn't want to make a career of it. I just needed to accomplish a few specific things.
