Thanks to MG23
Thanks for posting those links.
The Cyberus site holds links to both the Spectre & Meltdown research papers. I urge everyone with an interest in this problem to look at the site and like me; take the trouble to read and try to understand the the research papers.
Looking at some of the prime sources of the research helps to cut through the "rubbish" being peddled in the popular press: with the best of intentions no doubt.
