Meltdown, speculative execution and side-channels explainer.

Published: (Updated: ) in Miscellaneous by .

There are a lot of explanations for the current Meltdown/Spectre crisis but many did not do a good job of explaining the core issue if how information is leaked from the secret side,  to the attackers side.  This is my attempt to explain it (mostly to myself to make sure I got it right).

What is going on here generally?

How does it work?

I found these papers to be informative and readable.
