Nothing in this industry lasts forever. I'd certainly rather inherit a Java/Swing or Qt app from the early '00s than an MFC or Carbon dinosaur.

I'd further point out that the overwhelming majority of the moneyed interests still stack up on the side of permissive immigration policies. It is, after all, capital that benefits from a global free market for labor and an expanded consumer base. It's just about the only thing the Koch brothers and Soros can agree on.
Consider a grayscale morphological operator such as erosion. For each pixel, you would replace the value with the minimum value found inside a structuring element surrounding the pixel. This is kind of like a weird morphological operator with a 3x3 box structuring element, where instead of choosing values based on a simple criterion such as 'min' or 'max' you use information from an approximation of the image gradient. If the gradient magnitude is above some threshold, you select the neighbor pixel in the 3x3 structuring element in the opposite direction of the gradient.
This generally has the effect of making the edges more pronounced. Intuitively, you're distorting the image by "pinching" along the edges. To prevent weird color artifacts, they're using edges computed on grayscale data so that the identical morphological filter is applied to each color channel.
It seems similar but not identical to the method described in this paper: T. A. Mahmoud and S. Marshall, Edge-Detected Guided Morphological Filter for Image Sharpening 2008 http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.384...
In any case, great looking results! Proof that neural networks have not yet made thinking obsolete.
Is your contention also that SAT/ACT are vanity measures? The correlation between IQ and ACT is very strong, or in other words they are both strongly g-loaded and are good measures for general intelligence.

We also have ample evidence that general intelligence correlates with economic success:

Vanity measure, my foot.
Given that institutions of higher education aggressively select for high-scoring SAT/ACT individuals, and thus high IQ individuals, the burden of proof is on them to show that a degree results in significant socioeconomic success that cannot be explained by the preexisting psychometric attributes of the college bound population.
It sounds like a bunch of people who based their technology decisions on social media buzz instead of well-defined requirements are now running into operational problems and looking for the next trend to chase.
Even in legitimate cases of difficult to find specialty labor, programs like H-1B should be sparingly applied because they jam the market signaling mechanisms that create qualified candidates in the first place.
My issue with it is basically this: Harari's original insights and opinions are only mildly interesting. There is no single thesis presented (at least as summarized) that justifies an entire book. By grafting those ideas on to what is otherwise a rather dull exposition of mainstream anthropology, he impresses the less educated audience with knowledge, while lulling the more educated into an agreeable attitude by restating the well-known, at length.
It's a common persuasion and marketing tactic: Fact, fact, conjecture. Fact, fact, conjecture. Fact, fact, fact, bold conjecture.
And of course, being unwilling to slog through the filler, I'll be written off by Harari's acolytes as ignorant. But that's OK. I'm starting to regard the rejection of pop phenomena like this one a necessary self defense of my own time and attention.
a social, religious, occupational, or other group sharing common characteristics or interests and perceived or perceiving itself as distinct in some respect from the larger society within which it exists
A prerequisite for finding community support is to be a member of one. There are many communities. The commonality and social bonds between members form the basis of trust and the expectation of reciprocity.
When people perceive that their resources are simply being expropriated to benefit people they have nothing in common with, may never meet, and certainly cannot expect reciprocal investment from, they tend to withdraw from voluntary participation. Without that participation, communities simply die.
It's true that some communities have a larger pool of resources to share than others. But consider this before you condemn a synagogue for helping out a local Jewish family with money that could have gone to taxes to help someone arguably more in need.
It's sad that not everyone has a home, but the solution is not to demolish the entire block and apportion to each person an equal share of lumber.
Hitting a function button is not "typing" in any real sense anyway, use being so relatively infrequent. Can you really hit F8 consistently, without looking?
Maybe the doctrinaire solution would be to delete the function keys, if "thou shalt not look at keys" is the ultimate commandment. But that's incompatible with legacy needs.
Back in the pre-GUI days when use of the function keys was far more prevalent, software would sometimes ship with cardboard overlays to indicate which key did what action. The touchbar is bringing that old idea into the 21st century.
I would have preferred they scaled it back and include physical Esc and power keys on either side, but in other ways it presents a real improvement in computing UX which is too rare these days.
It's still somewhat early but I do already see software being written in Rust with best in class performance (take ripgrep for a prominent example), so lumping it in with Go and Python is really a category error in my opinion.
Personally, I'm still writing C++ for the platform support, etc. but not pretending to like it.
The thought was only that a large-radius ball would be able to approximate the sphere to within tolerance with larger stepover than a smaller tool. After bulk material removal with a more suitable cylindrical tool of course.
With a little bit of googling I discovered a different class of end mill called a circle segment tool, which could potentially make short work of the problem in a 5-axis machine:

Would love to see how Apple does it, but it's never happening.
I'm not really a machinist either, but let's not allow that to stop us from incorrecting each other on HN!
Not that it's a good idea - you need to be able to actually evacuate material from the surface you're cutting, and milling is different than drilling in this respect. But I imagine you could come up with a very fast two step program using a cylindrical end mill for plunging/roughing and a relatively large ball end mill for finishing.
Duck typing is also a minor win for "do what I mean" generics - you never have to worry about the type specification being too narrow, just pass an object with the necessary methods and it'll work until it breaks.
However, that was just to get started. WiFi setup from iOS failed with an "unknown error" multiple times. So I had to wait 20 (!) minutes for it to fall back to the old style open-AP type configuration, open the app, manually enter my SSID and passphrase...
I bought this one bulb as a curiosity, not expecting to be impressed, but honestly wasn't expecting to find an implementation as botched as this. The day/night cycle feature seems cool until it randomly stops working. The app often can't seem to figure out if the bulb is on the network or not.
Did I choose a lemon or is this par for the industry?
Another way is to measure surface specularity. Use one or more IR spotlights at different angles to the surface and strobe them on and off. A wet surface will have a different angular variation in reflectivity vs a dry surface, unless the floor is very shiny.

What this announcement actually means is that YouTube is going to become more politically active in their content curation. This is what a subset of their employees, as well as influential bluechecked Twitterati, have been lobbying for. As a progressive/neo-liberal institution, it will apply exactly the sort of differential policy enforcement that one might expect.
I won't delve into the details of how that applies to your examples because it would quickly become too controversial for HN.
Just imagine how the median Bay Area tech-person would parse out the details and you'll have the answers.
1 MPX module. 6 DIMM slots. 700 watt power supply. One 10Gb Ethernet port. Supports up to 12 cores.
Shrink the case somewhat in two dimensions and call it the Mac Pro Mini.
How hard can this possibly be you have all the parts right there...

There was a wordier post related to this but I think some stuff might have been purged with his separation from Tlon.
Anyway, the point is, if I’m writing from an alt-right perspective it’s my responsibility to tag it as such. Properly tagged, anti-semitism (for example) would not be an abuse of the platform. I don’t see how this is any less enforceable than the outright banning that e.g. Twitter practices now, and in fact it may be quite a bit easier, as you’ll get fewer “outlaws” who have to cycle through alts every week or two to get their message out to their followers.
One problem of course is establishing a small and universally recognized set of tags that work well enough for most people. Instead of very specific “content warning” types of things, it’s probably good enough to indicate broad political allegiance - black flag, red flag, brown flag etc. It’s rare that just a single word in isolation sets people off - offense taken seems to have more to do with the worldview motivating a given statement.
Then there’s the question of asymmetry. Say, for example, that As are mortally offended by B content but Bs don’t seem to care much about A content. In effect, you’d be creating an unfair burden on Bs simply because they’re more tolerant than As.
NLP algorithms can obviously help here, as well as crowdsourced tagging. So a single A user might have to be exposed to a B-type post to apply the tag, but we might consider that an acceptable loss over a large enough base.
This of course all assumes good faith. I suspect that As will simply be furious that Bs are able to talk to other Bs and neutral Cs, even if they never see those posts.
As far as iron content goes, it looks like the RDA is around 10 mg daily with a tolerable upper limit of 40 mg per dose. It's not clear how much daily intake you need for a person without hemochromatosis to experience negative side effects, but exceeding the RDA by several times doesn't seem like a major problem. Notably, the recommended intake is 1.8x higher for vegetarians vs non-vegetarians.
There is no excuse for a city with the per-capita wealth of San Francisco to suck as bad as it does, and "overzealous law enforcement" is not even on the list of problems the place actually has.
When a basic level of order is not being maintained, hand-wringing about a hypothetical police state falls flat with members of the public, some of whom are thinking fuck it, moving to Singapore sounds nice right about now.
For example, you can buy a Philips electric razor through Amazon Prime, but refill cartridges are only available through Amazon Fresh. The result: I made my first online order with Walmart and will probably make many more in the future.
