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.

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.

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.

It gets diffused to the point where it’s no longer distinguishable from the background.

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.

Just like the sibling, I admit I’ve never heard this definition of line rate...

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.

The standard model still doesn’t explain gravity, dark matter, or dark energy. There are still ways to go.

Interesting pricing decision by AMD. Given their performance, and no other competition in x86 market besides Intel, surprised they chose to sell at such a steep discount.

Sometimes, such pricing decisions can perpetuate “you are a weaker substitute” perception.

Argh, you are right - the ad fold made it seem like the article ended, yet there were two more paragraphs below it.

Still, rereading the article, the main body seemed a bit coy. It kept talking about how such black holes should not exist, yet I kept thinking “hasn't LIGO detected formation of 60+ solar mass black holes via mergers?”

But perhaps I’m in an extra criticizing mood before my morning coffee.

Misleading indeed. And I’m surprised the article did not talk about binary black hole mergers being potential sources of such black holes, since that seems like the most plausible theory.

It comes with a bias though, since your searches will bias towards finding asteroids that are easiest to find using your search method.
