It wouldn't surprise me. This city is corrupt as hell.

I must not be human. For factual information of this sort I just prefer the information. The story is irrelevant and usually too mundane to be bothered with

I always thought this was for two reasons: one as you say is to show the plumbing works, the other is because not passing the meconium (combination of stuff ingested while in the uterus) indicates other more serious conditions might exist

I’ve been in cat 1 and cat 2 storms. They’re awesome in their power for destruction. I’ve evacuated from a category 4 storm, which did a huge amount of damage in the city when it hit.

A category 5 storm is essentially going to destroy everything in its path already. What good would adding a 6th category do?

EM’s vector fields formulation is fairly straightforward: it’s all curls and divergence. Any 3rd (-ish) semester undergrad multivariate calculus course is likely to cover it in sufficient depth. “Mathematical Methods for Physicists” covers it in sufficient depth, for example, provided you already have a thorough understanding of the prerequisite material. Most undergrad physics degree curriculums should have E&M courses whose texts (e.g. Introduction to Electricity and Magnetism, Griffiths) cover enough of the details. If you want to pursue it further than an undergraduate level study, you’ll also want a good text on differential equations that has or is supplemented by material covering, e.g., spherical harmonics and Bessel functions (among other things). I wish I could remember what I used, but it was…more years ago than I care to say when I was an grad student.

I'm American. I've been in two economic classes: dirt poor (as in, more or less homeless, when I was a child, for a bit) and now on the low end of rich (net worth in the mid 7 figure range). I've seen both sides of this inequality, in America, personally. And new social circles that have opened up have given me something of a first-hand view of the "truly" rich as well.

I can list numerous ways that it's a problem, if you like. Here's one to start: "as long as people can move geographically" isn't applicable to those on the lower end of the economic scale. Your comment represents something generalizable about the rich, too: they are completely oblivious to just how hard and draining (physically, mentally, and emotionally) it is to be impoverished. I shudder to think what it's like for the poor in poorer countries.

This is ridiculous. Set aside the (incredibly optimistic, to be charitable) thinking that is going into the acceleration of these probes. The astronavigation itself is hugely questionable, especially with probes that aren't big enough to hold the kinds of equipment necessary to detect bodies that would perturb the trajectory, let alone make adjustments after encountering these.

I don't think people realize how mind-bogglingly, incomprehensibly HUGE space is. It's BIG. Like think of the biggest thing you can comprehend, and it's not even the size of an atom in comparison to even "short" distances in space.

At 0.25c the probes would blast through the centauri system in minutes. Hardly enough time to collect data more useful than what we already can sitting here practically stationary, even if absurdly far away.

It does not have 0 performance impact, it's not rare, and in applications that are in the hot path, error handling is also in the hot path.

That "detail of implementation" is what is used by user code, e.g., `myError.As(...)` uses reflection, implicitly.

I really appreciate the lack of magic in go's error handling. I do not appreciate the specific implementation of errors in go. It's inefficient (`reflect` is all over the place) and prone to obscuring the actual "error path". In applications of non-trivial size, it also becomes an obstacle to implementing structured logging and other components of observability. This makes debugging/triage of, say, a production incident harder than it needs to be.

Some tech is. Meanwhile large tech companies that are actually innovating (FAANG, near-FAANG, and FAANG-adjacent companies) are not. My comp has never been higher, and we're hiring. In the bay area.

It does take a long time, and also "real life" immersion, to learn a language deeply. It's the immersion part that Duolingo doesn't do well if at all. So it has to artificially slow down those things it does do in order to keep subscribers.
