This branch prediction inside a "gadget" needs to be mapped into the address spaces of both attacker and victim (i.e. shared lib). But even if the attacker can get this code to run on both sides and examine the dependent timings t

Damn, that is indeed possible. And I thought I understood these conceptually, now I have to read the papers again.

No, Spectre can only read its own memory, which makes it boring for programs, but interesting for stuff running interpreted code because it can suddenly peek outside, e.g. javascript. Meltdown goes one step further in that it can read kerne

Using a thread to keep mispredicting as desired is just one (though faster) possibiliy. It can be done in single threaded mode as well. Also doing that on purpose would again worsen cache performance.

I am regularly on the lookout for one which plays opus/flac plus the usual other formats and has much more than 4G storage, but I fear this type of gadget will die out before long. Or hopefully the Arduino and Raspberry type of hardwar

Tactile buttons. A touchscreen is impossible to operate without looking at it. I assume most of us MP3-stick users have listening habits which requires us to change the track or volume every few minutes, if not more often.

Also, what is the scientific name of the killer fly? There is no such article on wikipedia. And some more references on how compount eyes see mechanically , as opposed to chemically, would be interesting.
