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.

Either way, we're contrasting this with somebody who won't even make an account here on SoylentNews.
"Is that really true?" "I just spent the last hour telling you to think for yourself! Didn't you hear anything I said?"

Some of us have been anonymous (well, as much as possible) since USENET days, and we're not going to stop this side of the grave.

You might have been doing it for decades, but that doesn't convince me that it makes any sense.

Which is the smart thing to do in this day & age.
Which reminds me I really should shred *all* my online 'social' 'media' accounts.
