Loved this article! I initially was confused by how this transition would work with the conservation of angular momentum (since the electron would be flipping from spin ±½ to the opposite one). But then remembered that photons are spin 1 particles, so the math works out. Neat.
that's not right. if photons were truly spin 1, there would be 3 spin eigenstates available, but in fact there are only 2 (Sz=0 is unavailable). the pithy argument invokes the absence of a stationary frame of reference. for all practical purposes, photons are behave like spin 1/2 particles (despite being bosons). see, for example, the jones algebra / calculus.
The root of all trust is eventually some human, or group of humans. See "Reflections on Trusting Trust." At least so far, Apple has convinced me that they are both willing and competent enough to maintain that trust.
Myself, I stopped trusting Apple. There are now too many dark patterns in their software, especially once one stops using their services. And, DRM was re-instantiated, when iTunes started streaming as Apple Music. On top of that, their lies, such as those about the Butterfly keyboards being fixed, cost me a fortune. They fuck up the keyboard design, and then they buy the computer back for 40% of its original price, due to a microscopic scratch nobody else could see. And that happened twice to me. They put a lot of money into advertising themselves as being ethical, but that is only marketing. These, of course, are my personal opinions.

Purchased music is DRM free. Streaming music was never DRM free, since you arguably do not "own" music that you have not purchased. Though I'm sure record labels would love if they could get DRM back on purchased music again.
Absolutely! The distance to LEO satellites (like spacex or kuiper) is low enough that you would beat latency of fiber paths once the destination is far enough.
I found it interesting that a town of 100 had a runway capable of landing a 787. Was it built specifically for these kinds of scenarios, i.e. as an earliest diversion point for trans pacific flights?
For those of us who build distributed systems, it’s all about number of modes we need to design for, test, and monitor. If all I have to worry about is process death, I can design my service around that. Monitoring for process death is generally pretty straightforward as well.
Gray failures (like process slowdowns), on the other hand, are fairly difficult to design for, and detect. And it can wreak havoc on distributed systems if one of the nodes suffers a gray failure.
With one thread, maybe. But using multiple threads it’s not even that hard. I’ve hit 100Gbps using stock TCP stack and ~10 threads in Rusts Hyper without much trouble.
Another example, you can saturate 100Gbps with just 4 iPerf3 processes.
Is the tunneling protocol really IPIP for these overlays? Oh boy - that’s going to really suck on wide multi path networks like the ones used by cloud providers.
