Pattern matching isn't used in the Java community because it doesn't exist, and there is nothing inherent in pattern matching that makes it less performant than double virtual dispatch. And anyone who thinks the visitor pattern is more readable is probably not someone I want to code with. The visitor pattern is very high on boilerplate and makes the flow of your code harder to read.
For me, the whole point of college was learning how to learn. Everyone is forced to learn through traditional academic models and everyone tries their best to efficiently digest everything for exams. That said, I sucked at learning in an academic environment, but I learned what did not work for me.

Trying to find an article describing simple devices that use no external power to send a basic on/off signal (TX–only) over wireless (802.11 I think?).

Anyways, it was said to be used for simple applications that send a wireless signal to a receiver when the laundry detergent gets too low. Sort of like Amazon's push button thingies.

Because PG's essays are intellectually uninteresting and often times mistaken (which is a nice way of putting incorrect). If the essay's didn't have his name on it, they'd be harshly critiqued when they get past around these parts. If you're looking for academic perspectives, especially around the subjects of rhetoric and debate, there is absolutely nothing worth reading in those essays.

Quite frankly I find it annoying whenever I see someone linking to them. It's junk food for your mind, with some Silicon Valley sprinkles on top.

I mean look at this gem in the linked essay:

Re-Thinking the Exchange Model
Yoga was pseudoscience once. Now there is overwhelming evidence in support of it. Ayurveda descends from a similar lineage. The turmeric latte that the western world is infatuated with at the moment is just the tip of the Ayurveda iceberg.

The only reason Ayurveda isnt backed clinically is because it hasnt been subjected to it. But it will, exactly the way Yoga did. Yoga and Ayurveda are backed by science the just not in a clinical sense because it wasnt possible back then. They still went through an iterative development phase rooted in experiments and observation.

Also, the link you quoted doesnt discredit Ayurveda at all. Its about medicines sold in the name of Ayurveda having heavy metals.

It seems like they could all be interrelated.

Let's say I love to play video games and watch Netflix. Now, I could take time away from these things to workout, bathe, dress nicely, travel to some location, spend money, hopefully hook up with someone, etc. Or... just bring up some porn and masturbate (perhaps using a sex toy like a vibrator or fleshlight) and then get back to playing games and watching Netflix.

Real life sex with another person might potentially be better, but it's takes so much effort and money and there might not be a payoff in the end (no one has to have sex with you) that it seems like porn is a good enough substitute.

I think you've (re)discovered the -morphisms. E.g. anamorphism, catamorphism, hylomorphism. Data structure traversals of various kinds can usually be cast in terms of these morphisms.

As it turns out GHC is usually pretty good at optimizing this kind of thing due to the extremely aggressive inlining which is possible when you know that there are no side effects. It'll often handle compositions of traversals with no sweat. (I think it's sort of all lumped in as "fusion".)

EDIT: See tel's comment in this thread. He always understands and explains it much better than I can.
Sanitizing history like this has a very negative consequence. We are taught to believe that there is such a thing as bloodless revolution. And that makes it easy to dismiss movements like blacklivesmatter any time someone commits violence in the name of the movement. After all, if the suffragettes got justice without firing a shot, why can’t everyone else?

While I she agree that 8-11 is an exaggeration, it is easy to get up to 7: 1 right turn lane, 2 though lanes, 2 left turn lanes, and then 2 more through lanes in the opposite direction. Those aren't common in areas with lots of pedestrians, but I do see them all the time in other areas which do have cross walks (with traffic lights, if course) which I have seen used on occasion. Sometimes these even cross highways with 60 MPH (100 KPH) speed limits.
I’m not sure that’s a counterexample either? The claim is “if X is in moderation, then X is fine”. If we let X be necessarily not in moderation, the claim holds of X by impossibility of the antecedent.

IOW “if X is in moderation, X is fine” is logically consistent with “some things cannot be in moderation”.
Sure. That's why I said plausible.

I was also thinking that within pockets of larger territories there were probably areas of relative autonomy. Neat lines of borders and centralized control within them seem like a relatively recent invention, even if the larger narrative ends up more or less telling an accurate story.
.. or any kind of privacy-related opt-in, if the opt out is readily available. Currently websites try to work around this by placing a "manage" link with countless options which makes it work to opt out, but that doesn't seem like something that will be allowed for long by the regulators.

Privacy opt ins are effectively donation buttons, and we know how well these work.

Energy Theft Detection in Centers with Digital Protective Relay Deployment
Let me add that there exists a similar echo chamber when it comes to questions regarding cryptography. Way too often questions about how to do this or that in cryptography are put down by a "you don't" or the generic "don't roll your own crypto", which is hostile against curiosity, learning, and knowledge and on top of that unfriendly towards the one asking. Often when I read it, I feel the hacker ethos is being insulted.

While I think there are reasonable arguments for the security of (certain) self-made crypto, taking that security aspect completely aside, we need new people in every field, and cryptography is no exception from that. We should embrace newcomers, not tell me to not do what would teach them so much. Admittingly, one can easily mess up, but then tell how and what to take care of instead of just telling them not to try anything at all.

What does it take for people to see that for all the problems technology and markets have solved, they have unintended side-effects that, after enough time, can become global problems?

It is fairly easy to see this and some portion of people see it immediately. Unfortunately, another who profit from these things ask "what does it take for people not to see and stop these things?" and the answer is fairly visible in the way global warming has been [not] addressed.
It's only recently that Peterson has formally denounced the alt-right. Before, he was on JRE saying things like "as far as I can tell, Kekistan is a defense of comedy," when it was obvious to everyone else that it was blatant nazi propaganda. Only when the alt-right became emboldened enough to attend his lectures and start asking pretty direct questions about the Jewish question, globalist conspiracy, etc. that he finally saw what his audience was becoming and sorted himself out.

Most people on the left don't think that JBP is a nazi, or alt-right, or whatever is the inverse of the "postmodern neomarxist" boogeyman. People on the left are critical of JBP because of his blatant misreadings of Marx, Deleuze, Foucault, his confusion about Bill C-16, etc. His overly broad equivocation of postmodern critiques of power and Marxian class theory is the basis of his incredibly nasty attacks on these so-called "postmodern neomarxist feminists" yet he has published no real thesis.

He can't even be said to be critical of leftist ideologies because he never puts forward any real arguments, and all he does is signal that the left are evil.

And I'm saying all of this as a leftist who has supported Bret Weinstein from the beginning. I accept the postmodern feminist criticism of identity politics and agree that SJWs and their constant search for categories is harmful to the left. I would love for Peterson to put forward an actual, rigorous criticism of leftist ideology, but frankly he doesn't seem to have one.
Astronaut and moonwalker Alan Bean dies at 86
I think that is a really bad line of logic. There are lots of things that have been around for a long time and make some people plenty of money that are bad things. Pyramid schemes fit your definition - should I start buying in?

The opposite way to pose this is: Cryptocurrencies have been around for 9+ years, and there has been literally 0 use for it apart from conning rubes on the internet. The important thing to ask is whether it has a purpose and has it delivered on that purpose. There's really only one theoretical purpose that it's meant to serve - being free from tyrannical government. Well that kind of worked when capital fled into it from China - but there's also been crack downs. It also doesn't explain the US fascination.

I think there comes a point where 9 years in, you have to ask: What purpose does cryptocurrency serve beyond enriching people who are already invested.

NYCLU and Columbia University have a 2016 video (starts at 2:50) about the corporate origins and privacy policy of Google's LinkNYC surveillance kiosks in Manhattan:

https://livestream.com/internetsociety/hopeconf/videos/13081...

Village Voice covered the topic, https://www.villagevoice.com/2016/07/06/google-is-transformi...

This freedom to opt out entirely is also the last argument that spokespeople for LinkNYC and the city itself fall back upon when challenged with privacy concerns: If you don’t like it, you’re welcome not to use it. It’s a disheartening place to land, especially when discussing infrastructure that’s supposed to be serving people who aren’t served otherwise. To Moglen, it’s simply an unacceptable conclusion. “That’s what they want us to believe, that we have a choice between isolation and monitored connecting,” he says. “Those are not adequate choices in a 21st-century world: We are designing the net to track you — if you don’t like it, don’t use it. The human race is shifting to a fully surveilled and monitored superorganism — if you don’t like that, stop being human. That’s a poor outcome. The United States is a society that was based around the idea that human beings can have liberty. So give us liberty! And don’t tell us that otherwise we can have the death of the net.
You’ll disagree with him, I certainly do, but I wouldn’t dismiss him.

I think he’s too utilitarian on family and marriage, but his position is intellectually defensible. For example, he’s pro gay marriage but believes research saying children have better outcomes with exposure to both sides of the (traditionally gender-based) parental roles. He doesn’t claim to know a solution to the latter, or even that one needs to be be found. Only that it should be researched and discussed.

It’s not hard to take that kind of view and spin it to something abhorrent if you take away the nuance and context.
I agree that capitalism is not at its structural limit, I imagine within the next 50 years ideological descriptions of resource management (capitalism, communism, syndicalism, etc.) will begin disappearing in favor of something like "Keep feeding the replicators." The human and environmental costs of competing economic ideologies don't have much tangible payoff, and discussions of capital are illusory compared to real measures of human happiness.

If a guy was like "I can't grow grain here but with a small material surplus the people here can live happily and have families and exhaust the local mineral reserve for whomever needs it," at least to me the answer would be, "Provide them with a small material surplus."

I program computers but would have to take a pay cut and assume large debts, etc., to begin operating a fruit orchard and wood mill. I might become happier, but the economic value of that decision and whether or not I would survive it economically is unclear. However, this seems to have nothing to do with economic systems, at least to me.

What makes an investment in 'this Bitcoin crap' any different from an investment in say Facebook shares or Snap shares? Aren't they just unnecessary digital crap too that nobody actually needs?

Bitcoin has become the gold standard for crypto and many people invest on the basis that there'll be huge growth in the area of blockchain technology and tokenised digital assets in the years to come.

If Bitcoin remains the gold standard for crypto then it's value will rise accordingly.
I totally agree with your comment, except for the last bit about 64GB of RAM being unreasonable high.

Is it unreasonable to spend thousands of dollars on memory for Enterprise-grade, production-level servers? In my experience, you'd almost certainly better be using over a hundred GB of RAM in a server if you want to maximize the overall compute density.

To be clear, plenty of Desktops and all workstation-class laptops support 64GB+ of RAM.

It's not exactly snake oil because you used to be able to buy thinks with it. It's just become snake oil. Maybe that's pedantic, but I don't think it would have become large if it hadn't initially been on a path towards being useful as a currency.
Google seems to be all over the map on this one. I would have thought that minimalism would be a good concept when building to reduce consumption; but rather, Google is going all-out with an enormously large and complex proposal it seems. And it is full of contradictions. It's also tone-deaf and reeks of a 'we know better than you' attitude, which is something Google needs to not fan the flames of.

> The area will have plenty of sensors collecting data - from traffic, noise and air quality - and monitoring the performance of the electric grid and waste collection.

...

> Sidewalk Labs told the BBC that the sensors will not be used to monitor and collect information on citizens, rather it will be used to allow governments to be flexible about how neighbourhoods are used.

Those two sentences are not compatible. The sensors will be used to observe - surveil - citizens in cars, citizens talking and at the same time, won't be used to monitor or collect information about citizens? How?

Does Google have any plans to describe how they will eliminate human-spoken conversations from their noise detection? Such work can be done. Will they do it? That seems like Problem #1 to address: Google claims they will shove microphones along the streets everywhere but "promise us they won't listen to you"........okay? I don't buy it for a second. Talk to us about it, at least, and don't just say "we promise not to monitor human speech" and leave it at that. This is a hugely important conversation and Google is ignoring it. You can't just plaster public space with corporate surveillance tools and then walk around whistling and ignoring the huge social movement against your never-ending privacy invasion.

> What is clear is that green will be top of the agenda

None of the proposal sounds green to me. The amount of effort that will go into building it seems likely to offset any gains it would save over time through pollution reduction, etc.

The entire thing sounds like it would need new factories, new dedicated infrastructure, and none of it is remotely green-sounding. Where will all of this stuff come from? Is it truly better and less pollutant than an old-world, more simple solution might be?

I'm hopeful for Sidewalk Labs. But it seems like the Reddit Redesign to me: making every single obvious mistake that you could make, while the outside world yells at you "please reddit don't be digg 2.0! please Google don't make a massive dystopian total-surveillance society! please!)

Video games are now more interesting than Hollywood productions; most TV shows/movies are borefests comparing to what you can experience in some advanced videogame with almost photorealistic graphics. Soon we will be able to deploy more AI-based goodies like completely replacing NPCs with people we know by providing single photos, realistically synthesizing their voices etc. At some point we will be able to directly stimulate brain's pleasure centers which might kill off drugs, porn, art and as a side effect, civilization. Our present time is already looking like a badly directed reality show; I believe it is going to be a lot worse, Kafkaesque and artificial.
