I once wrote a thing that went all over gmail figuring out where all the pending mail was supposed to go and presenting it as an interactive dashboard. It was easy to do in Go because baking in the html templates, static assets (like d3) and backend logic is pretty simple with Go’s standard libraries and build system.

I wrote another thing in Go that determined the backend latency of an anti-abuse system within Google. That prober made about ten million requests per second. Again I chose Go (over C++) not for its performance but for the ease of giving that thing a fancy interactive status page.

Yep, and those people will likely be sending THEIR kids to elite private schools with 5:1 student-teacher ratios and 20-40K/year tuition for elementary and high school. These schools will DEFINITELY NOT use "AI" for grading.
Very speculative, don't take any of this as gospel:

The very concept of "the stack" implies a C-style evaluation model.

Having a single address space for both code and data mainly just gives an opportunity for optimisation to fail.

Everything-is-mutable gives a lot of opportunity for optimisation to fail. The compiler wants the program in SSA form, it register-allocates to a bunch of reused names, only for the CPU microcode to figure out which uses of those names can actually be used to mean separate physical registers.

Arguably the failure of VLIW (in particular Itanium) was because of C: those processors could (maybe) have run more constrained languages very fast, but it was difficult to compile C to run fast on them.

Labour force participation is a complicated question deeply intertwined with the opioid crisis, increased rates of college attendance, the mis-use of federal disability insurance and other factors. Quoting labour participation without reference to demographic shifts creating more retirees, moreover, mischaracterises the statistic.

Blue LED inventor and Nobel Physics Laureate Shuji Nakamura was my former classmate at UF MSE back in the late 1990s. At the time a pioneering institution in MOCVD of wide-bandgap GaN. Even back then there was a sense this would be a world-changing materials discovery.

And we may be on the cusp of the next brilliant revolution in lighting displays with solid-state Graphene. The graphene / graphene-oxide boundary represents a near infinite bandgap differential. And with a controlled applied voltage, can be tuned to any color in the visible spectrum and beyond.

Combined with extensive end user testing in the Human Psychology Lab this could very well lead to a breakthrough.

In my own experience the most glaring is the 5am wake up time. When pupils are dilated. And you are checking any overnight messages from Asia or Europe. Occasionally Nite Mode will simply fail to register and you get a good blast of photons directly on a still sleepy and sensitive retinal plane. Long term repeated exposures can't be a good thing.
Eq. (14) is just the expression for a dipole. Keep reading to see the full solution in the simplest case (circular plates), Eq. (19).

Since you insist: your derivation goes wrong right at the start by, as you say, "ignoring curvature effects", i.e. by considering radial distance only. By doing that, you are effectively imposing spherical symmetry; you are not doing parallel plates, you are doing concentric spherical shells. That makes the whole exercise pointless, since it's obvious from symmetry alone that such a device could never produce a net thrust: there is no preferred direction for the thrust to act along.

To answer your final question, just look at Eq. (19): make the plate radius (R) larger.

That answer should also be perfectly obvious from the limit case of infinite plates. A correct derivation for the general case must reproduce that result in that limit. Yours does the opposite; it gets worse the larger you make the capacitor. In the infinite limit, it is infinitely wrong.
Bravo guys.
What an annoying click bait title. But the article is good (if short). I guess I wonder why something like this is even legal. It seems corruptive of the marketplace to just hand billions of dollars to some companies and not others and it seems there's no good way to stop it as long as this is a tool that municipalities are allowed to use in competition with one another. Has it always been this way or did we have a fix in the past?

People working at radar installations were exposed to much higher dosage of EMF than the usage of mobile phones since the second world war. Are there any studies about effect of those?
Yes, I agree. It makes far more sense to make guarantees in a language, that two values are compared using a metric that is invariant. Especially in a language like C, where we expect it to be a very thin abstraction over the machine.

You have this somewhat backwards.

Cities have loads of data that define property lines. They could keep it on paper, but more and more they keep it in computers now. Surveyors take that digital data and convert it into its precise real world marks. This has literally nothing to do with whether the real world digitizes well, and if really stretched only proves that it certainly does because that's the entire basis of property grants.

Further, pointing out a massive civic project in the middle of a large city as some sort of counterpoint, when it is in reality still not that complex at all, doesn't make your case.

I was thinking "an hour" and thinking "damn that's impressive" (it would be 8.3 million per second), or obv per minute or per second would be even more impressive. (And someone is using that really heavily). Instead the end of that sentence is "per month", so 11,415 per second.

There's a second option I just recently understood in the "high employment == high wages" equation - employers can just wait longer for hires at the wages they're offering. And, based on the way employers keep the jobs posted for months or years, it seems to be working for them.

I guess in a way it's just another signal that the jobs being filled aren't that critical.

When you eat too much of it, certainly.

It is generally thought that we eat way more salt than is considered healthy. Too much salt increases the risk of high blood pressure, cardiovascular diseases, and kidney failure.

The Dutch government — to cite just one example — states that 80% of people in the Netherlands eat too much salt¹; i.e., more than 6 grammes per day, and lists the health issues mentioned above.

Conversely, eating too little salt is quire rare nowadays due to the high amount of salt in store bought products.

> To me Rust is more a C++ replacement than a C replacement.

People make this comparison a lot, but it’s not fair. Rust is far simpler, in terms of number of features of the language, to that of C++. It’s fair to say that Rust is far more expressive than C, but this just represents an initial learning curve that is higher than C, but not as high as C++. The type system is fairly simple in Rust, but it can be used to create very complex things. It does take time to be able to read it, but the guarantees you get from it are very powerful.

> a C replacement should keep the procedural nature of C, with closures perhaps, but not go further in terms of paradigm

Why leave all of the language development of the last ~50 years on the table? Iterators in Rust are amazing, algebraic data types (enums) allow for simple state machine constructs, lifetimes guarantee memory safety, default immutable memory and single mutable owner mean no more concurrent memory modifications. It’s safer than Java, and as fast and memory constrained as C, what’s not to love?

These are amazing features, that allow for amazingly stable programs. To put it succinctly, you get to code once, and then rely on that code for a long time, to focus on building features, not bugs.

It would be helpful to distinguish between actual cash outlays and tax credits that kick in only when the company is producing and supposed to pay taxes.

It's not unreasonable then to forego $0.5 million tax revenue for a long term, high tech manufacturing or engineering job that might generate another 5 jobs down the line. Not to mention the value of an environment that attracts other similar companies in the future without other incentives.

Even actual cash outlays for things like free infrastructure are not something the company can take with them, they remain in place for decades for other investors or urban expansion.

Most bikes in Amsterdam are stolen at some point. There is little crime except when it comes to stealing bikes. Mostly because the police doesn't do anything when bikes are reported stolen, so unless you're caught red handed you have little to worry about.
Likely happened in the past but at a different scale. Improvements in communications technologies and logistics have made physical location less important than it once was. It's much easier for most entities to pick up and relocate than it was when most economic activity was tied to local resources. There are of course many exceptions but for the tech industry, the main thing holding anyone in place seems to be the local talent pool. Perhaps improvements in remote work technology and universal broadband access will even diminish that as a nucleation point.
The sheer quantity of edge cases, special cases and normal use cases when dealing with these "mundane" entities is a quality all its own. These use cases we automate or help automate are not by themselves all that complex normally. This is where they differ from quantum mechanics, synthetic chemistry, etc., in that use cases in those fields are usually not as accessible to the layperson.

Yes, go deeply enough into those "mundane" entities and you will eventually hit a abstraction strata high enough where it makes sense to apply a Lisp/functional language/<<insert favorite abstraction tool here>>.

But in the meantime, many times even the domain experts themselves don't realize there even exist higher abstraction levels of their domain. Incrementally getting there with the lower-abstraction-capable languages often better fit their organizations' staffing budgets today. Lisp programmers by and large I've found are scary-category smart. Consistently staffing that kind of smart takes bigger payroll budgets than most organizations are willing to stump up.

Today, the tooling around getting "good enough" results in most fields for most projects tends to even out whatever programmer productivity efficiencies Lisps brought to the table, enough to the point where most managers don't want to tackle the higher complexity of managing a Lisp team.
Just to agree and emphasize, a more accurate title would probably be "Breaking eta equality breaks the monad laws." A lot of equational reasoning in general goes out the door at that point, not just monads.

More generally any kind of system that is able to introspect and differentiate between non-equivalent evaluations of itself tends to break a lot of invariants.

Imagine trying to establish equivalences between sequential and concurrent processes if the processes in question could introspect what thread it was running on and changed behavior based on that.

So yeah. Seq is what breaks things here. Not State. But even Haskell sometimes has to compromise purity for practicality.
There are a slew of people out there who can keep a healthy relationship with someone much easier than keep a job. I'd venture to say that most people find benefit in finding a life partner. Hence why they keep doing it (even multiple times).
