Gravitons, Neoverse... you'd be forgiven for thinking AWS's second-gen 64-core Arm server processor was a sci-fi In conjunction with its re:Invent show in Las Vegas this week, Amazon Web Services offered a preview of the next iteration of its Arm-compatible EC2 instances, which will use its customized Graviton2 processors. The first generation of Arm-based EC2 servers, dubbed A1, used AWS's Graviton1 processor line, which debuted a year …
What’s still missing, sadly, is ARM versions of the “t” instances and Lightsail.
The “t” instances are burstable, i.e. you pay for some fraction of a CPU core on average but can periodically use more. I use these for servers that typically tick over with maybe 5% load average, but sometimes need more - most often when they do something like a database backup dump or when I log on to install something.
Lightsail is based on the t instances, but they’re bundled up with a generous a cheap monthly bandwidth allowance. Thus makes AWS much more competitive for bandwidth-intensive applications.
So sadly, much as I’d love to use ARM instances (and I’ve tried them out experimentally), I’m not currently able to do so.

Interesting but inaccurate. That paper states:
"... get the required leakage information from the ground wires at the remote end of VGA, USB or Ethernet cables."
Ethernet cables do not *have* any ground wires (unless we go back to the days of coax Ethernet).
I also question whether what is claimed could be carried out in anything other than a strictly controlled experiment that would never occur in real life.
