i don't think the information that unprivilleged VMs can obtain from that is necessarily reliable. for example with Xen as hypervisor only dom0 is privilleged (as management console for the system) and still it needs to call dedicated tooling in order to read or manage CPU features like clock speed or frequency scaling
Yep, and that makes implementing addition of "Connection: close" in an HTTP reply at the HTTP/1.1-server's side somewhat tricky: you ideally need to read all of the pipelined requests from the client before closing the connection, which is usually something you'd rather not do. But if you just close it, you risk your client getting a partial reply, so you better add "Content-Length"/"Transfer-Encoding: chunked" in your reply as well... but one common reason to do connection-close reply is when you don't know the content-length beforehand, so — I hope you implemented chunking correctly :)
Even if you just close it, and it RSTs, and you implement chunked etc. properly, the client can't even necessarily read all of the information already sent to the client.
If the client does a read() after the RST gets there, any data in the receive window is gone, any packets that might have been dropped and need to be resent are gone, etc.
Signal doesn’t provide anything in the message other than… “there are pending messages.” Signal wakes up, fetches them, then generates notifications on the phone itself.
“We learned that specifically on iPhones, if one’s settings in the Signal app allow for message notifications and previews to show up on the lock screen, [then] the iPhone will internally store those notifications/message previews in the internal memory of the device,” a supporter of the defendants who was taking notes during the trial told 404 Media
Doesn't indicate this is an issue when you have it set to preview when unlocked.
Tariffs are quite different than a sales tax because they can select winners and losers in a market. Cane sugar vs sugar beets etc. https://en.wikipedia.org/wiki/Sugar_beet
However, they don’t have to be high enough to change who wins, even small ones adjust how much foreign subsidies manipulate the market. Foreign governments should consider how much US corn syrup impacts domestic consumption for example as a separate issue from how it impacts domestic sugar production.
China’s currency manipulation has second order effects that benefits Americans. We don’t necessarily want China to stop, instead the goal should be to minimize the harm while extracting maximum benefits. A small tariff that caused them to double down on currency manipulation would be a massive win.
