I don't think that it did. And I don't care about what the humanity is consuming, as long as it doesn't pollute the world excessively.

Your rights end where my rights begin, etc.
> That is the definition of a function, but it's purely a formalism...

Isn’t the function definition meant to be interpreted as “maps consistently to exactly one element of the codomain”? So an ordered pair of R^2 is still one element of R^2

It seems the parent has just mixed up the domain and codomain, because under that assumption he would be right about both the definition and bijectivity
I guess it depends on how you define racism. One common definition is negative discrimination based on race. In order to be anti racists you must negatively discriminate against a race, therefore anti racism is just another term for racism.
Yep, went there to learn how to use vectors to replace methods...
As much as the political salesmen love to emphasize the differences, Soviet style bona fide government central planning and American style corporate central planning have many commonalities.

You can switch to a following-only view, but it resets whenever the app is re-launched, which is a real scummy pattern.

Agree on the need for a proper website that isn’t read-only. I get that most usage will come from mobile, but for the more interesting and prolific posters, tapping out blurbs and interacting with others on mobile is a second-rate experience that doesn’t feel as rich when compared to using a web app.

Meta’s working on it, so hopefully we’ll see if the culture of the service shifts away from that Instagram feel.
They're 12V contained electronics with a wire, e.g. adding a boat horn to your car is an hour install at most.

The more you think about it, the more you realize that most people's vacations are to places where they don't have to drive everywhere. People get on cruises because "they have everything". Disneyland is just walking around to stuff. Vegas is basically one strip with huge sidewalks and a whole bunch of stuff. Resorts are... resorts. Yet no one seems to want to have any of that when they are not on vacation.
I'd say Ian M. Banks Culture series [0]. Arguably also written in the 90ies but it draws a bit more of a positive picture. I'd love to live in an environment like that.

The Day the Universe Changed (also by Burke) was also exceptionally good.

Similar premise, but focusing more on philosophy and understanding, and not tracking linearly through time.

There were another two Connections mini-series, though they were IMO not up to the mark of the first. Good, but not truly excellent.

Because competive debates are dumb and a dumb way to make up your mind about anything. The objective of the competitive debate is not to find some kind of truth or meaning or understanding but to win the debate. No honor or pride or authenticity needed. It's meaningless. And Ks are just the inevitable endpoint of this pointless exercise. They don't even have to pretend to debate the topic now, just win becaue that's what the judges like. It's actually always been like this, even without the Ks. If it was a right leaning jury you could win using what abouts and saying "woke" as many times as possible. The Ks just make the uselessness of debate as a format more obvious.
In retrospect, I found the actual debate part of debate to be mostly a chore. But the research and learning parts were a lot of fun. Some things I learned about in high school because of debate:

1. A lot of stuff about the actual topics that we debated. Both in substance, and also in the relevant components of federal policy tools. Eg, I still know a lot of useless facts about US agricultural policy, US foreign aid policy c. mid-2000s, statistics on realistic offshore wind production capacity c mid-2000s, etc. Contra the narrative here: the actual policy topic stuff doesn't tend to age very well...

2. How the Federal Reserve works: its history, its basic structure and mandates, the reason for its mandates, how decisions get made, how it interacts with other components of the federal government, etc. Also weekly deep dives into quantitative easing as it was being invented. Consequently, also quite a bit about the BOJ (I graduated in 2009, so my peak debate participation years were 2007-2009.)

It's very important to note here: fiscal policy was NOT the debate topic that year! The topic was alternative energy. But we could link into fiscal policy via alternative energy by arguing that green energy investments were in essence stimulative fiscal policy and would trigger inflation when combined with QE and interest rate policy. And then we could benefit from having the most up-to-date evidence about what Bernanke would do (see #6). Again, in 2008-2009. As high schoolers. Without much or any adult direction.

What other extra-curriculars let kids play these types of games?

3. Some really useful law and policy specific research skills. How to find and read proposed legislation. How the legislature actually works. How to find and read court opinions. I know this stuff sounds trivial, but I still regularly have conversations with 30-70 year olds who have never actually read a bill or SCOTUS opinions, so it's apparently not something that people learn how to do in high school, or college, or graduate school.

4. Yes, also quite a lot of critical theory. (It's part of the game and I don't get why people get so fussy about it. If the argument is bad, win. If you get an unfair judge and lose anyways, oh well. It happens and winning actually isn't the point anyways.)

5. But most importantly, lots and lots of research skills.

6. Quite a lot of natural language processing to help with 1-4, which became surprisingly relevant lately.

Policy debate has its flaws. But, at least at my high school, there was no other activity that came remotely close to providing the pedagogical opportunities available in debate. Perhaps at elite private schools or schools in the wealthiest suburbs there are good alternatives.

IME, that's still true now. This year's topic includes AI. I judged some debates this year and learned some stuff about AI by judging rounds. I'm not an expert or anything, but my PhD was at least AI-adjacent and I've been in AI labs for a good half decade now, so it was kind of surprising to learn new stuff from high school debate kids.

Anyways. I'm more convinced than ever that the kids are okay. Let them play their word games.

I think everyone should just stfu and do experiments. Let the law of physics to decide who is the winner. All these side stories are irrelevant nonsense trash.
Counterpoint: part of how I learned from smarter people was to copy their habits, and part of their habits was to read good books with good practices.

Learning how to read non-fiction books, as I discovered, is actually a skill that needs to be learned, as my historian friends who wolf down thirty books in a week will tell you (the trick is to read only the parts you need instead of reading cover to cover, though I am still learning how to learn).

And counterpoint to counterpoint: While fields in the humanities are 'book-based', CS is mostly 'article-based'. And furthermore, on the bleeding edge, textbooks don't exist yet, documentation is shoddy, and sometimes you have to read the original source code.
Why aren't we going electron lithography? As a laymen I think it should easily be able to surpass EUV in terms of resolution. I would imagine there are very good reasons why we aren't seeing it.
This reminds me an amazing piece of documentary[1] I've watched a couple months prior about a man who tried to "scam his way onto a Nobel prize". It really goes into showing how the majority of the system is based on trust and reputation and without well skepticism fraudsters can thrive.

Excellent story about the government not allowing anyone to be too smart or beautiful.

While their complaints are legitimate, it seems to go against the spirit of the GNU Boot project.
If you make Apple devices totally worthless to thieves, you discourage theft. Make them bricks which can't even be harvested for parts.

That's the goal apparently, and it makes sense.
I like to think have a lot of friends at surface level, and I used to have solidly close friends, but pretty much all of them moved to other states, so I see people in real life at about the same frequency as you. Some of them I maintain a digital friendship really well, but it is a challenge. This is a transitional period for a lot of people. COVID did not help this. I've also always been pretty introverted so my main method of making friends is "daisy chaining" off of people I already know. Like if you know one person, see if they can invite you to a get-together with other people they know, and so-on. That way you also have the added trust factor of "this person is vetted by another person I trust", instead of going in blind. If you have friends who live in other places see if you can arrange something like a digital movie night where you watch the movie at the same time. There is also online chess or online Scrabble (Lexulous is an online Scrabble clone) that you can play while chatting over the phone. My ideas might not be the best of help, but you certainly aren't the only person in your pickle.
Except I'm not saying "only consider one instance of slavery that is bad". By all means, consider them all. Then there's the question of whether slavery can inherently be remotely good. Also, I said "instance of slavery" but that downplays the scale and impact of the systems that enabled slavery. Of course I'm not pointing at an example of slaves being mistreated as my only reasoning.
No, they get it on the back end in the form of (sometimes obfuscated) kickbacks.
Could be hydration related. Lower ABV drinks contain more water relative to the amount of alcohol you're drinking.
I know this is just an example, but is this an accurate representation of what these arguments are like?

> Western societies are structured on Enlightenment-era philosophy that fundamentally does not value Black people as people, and defines them as slaves. Even though documents like the Constitution have been amended to end slavery, it created a society that is rotten to the core, and the only way to fix it is to burn down civil society.

I found this particular one strange because it sounds like essentialism, which is both a hallmark of Western philosophy and a common target of critiques by critical theorists and poststructuralists.
> How fast should you accelerate your kid in math?

Definitely not to the speed of light. I understand 99% of that may be alright.

What mows a lawn? A person, or machinery?

In English, either can be referred to as a "lawn mover." However, most often "lawn mower" has the most direct meaning: the machine.
>Critical theory is not revolutionary. Socially, it is dominant (particularly among that demographic). It is actually truly revolutionary to disagree with it, e.g., take the stance that capitalism is an effective way of organizing labour.

There is simply nothing revolutionary about advocating for things the way they are, even if that doesn't reflect the majority opinions of those making and judging the debates. I agree that personal attacks and virtue signaling is detrimental to a reasoned discussion, but these are highschool kids that live in a country with the highest incarcerated population in the world (the majority being black), extreme wealth inequality, a political system that offers geriatric candidates who have no interest in introducing radical social policies that might give them a future to be hopeful for. What, you think they're just going to sit back and listen to a bunch of old people tell them that everything is cool and the system works? The system clearly doesn't work! They don't even have a baseline for a reasonable discussion, to them the whole world is fighting against their futures and the "truth" doesn't matter if it will crush them.
This response is quite bizarre.

First of all, you seem to be conflating the employee-employer relationship with the consumer-seller relationship. As a consumer, I don't negotiate with the factory workers who built my car, because I don't even know them. The factory workers negotiate with the car company, and I negotiate with the car dealership. The car dealership is not my employee, nor am I their employee. We have a one-time transaction, and then I probably never see them again. I didn't perform any labor for the dealership, and they didn't perform any labor for me. All they did was sell me a car. Of course the salesperson performed labor for the dealership, and maybe the salesperson got a cut of the car price, but I don't know for sure, because that's between the salesperson and the dealership, in their negotiated contract. My contract with the dealership was, I give them $X, and they give me vehicle Y. FWIW the dealership never even asked for a portion of my income, and I didn't ask for a portion of theirs. Neither of us had the leverage to do so, and we didn't have an ongoing financial relationship, so it didn't make any sense whatsoever to do revenue sharing.

I'm currently self-employed and thus get perpetual income from my own software. Before that, I was a longtime employee of a software company, and they had a revenue sharing plan. This was actually their idea, not mine, to entice employees to stay with the company. It was part of the negotiated contract.

Writers and actors have an ongoing relationship with the studios. They're more or less employees and have negotiated a contract that gives them residuals. It's all about negotiation. Both sides agreed to this. The studios aren't trying to abolish the concept of residuals. The only sticking point in negotiations is the streaming business, most of which now benefits the studios alone, so of course they don't want to give up more money. It's a financial negotiation that you're trying to turn into some strange philosophical issue. What you get as a result of negotiation is simply a matter of leverage. Some have the leverage, some don't. Labor unions tend to give labor more leverage. Actors have a lot of leverage, because people go to the movies to see the actors, not to see the producers.

But the idea that two functions can be thought of operating additively on a vector - or space - seems... trivial.

No, the functions are not operating on a vector, the functions themselves are vectors, which means you can do things like define a linear transformation L and then you have things like this:

L(af + bg) = aL(f) + bL(g)

You may also define a norm on a function space (such as an L^P space [1]), ||f||_p, which maps functions to non-negative real numbers and obeys the properties of norms that we expect, such as the triangle inequality:

||f + g||_p <= ||f||_p + ||g||_p

I don't care about any of this drama.

I could be wrong but as I understand it the claim is that lanarkite and copper phosphide, when ground together at a 1:1 ratio, sealed under vacuum in a quartz tube, and heated to 925C, become a *room temperature superconductor*.

This claim is incredible and verifiable, so much so that it annoys me to hear any side chatter.

We should know "soon" (c.f. https://www.science.org/content/blog-post/breaking-supercond...)
I suspect the idea is that there can be many functions that fit a particular vector, because there are more functions than vectors, but I nay be wrong.
Tangential rant.

Has tablet computer really improved since the last Google Nexus 7 tablet, which was released in 2013?

Seriously, I was in the market for an affordable tablet, and quite bizarrely the tablet computers today have significantly underwhelming spec compared to a phone of the same price point.

There is no budget tab from known manufacturers. Even at IPad level prices, the android counterpart is quite underwhelming. I don't how it happened by it seems like IPad is the only tablet computer to get. For people on a budget there is no other viable option then to get a used IPad and news like this makes me kinda mad.

What the heck is even going on? Like in 2012-15 era there was bunch of variations of tablet computer of different price points. These days everyone from toddlers with their padded covers and graphics designers with an apple pencil is using an IPad.
Wouldn't that be a very different complaint, focusing on what judges reward vs what the actual arguments are? The original article touches on that more than the comment here.

Instead of talking about if the tactic is valid or if the judges are doing a good job with it the comment here took a major tangent towards "actually the whole line of thought used is obviously flawed and wrong" with a dose of "nobody here is thinking about it they're just following the crowd." Which is suddenly not about tactics or scoring at all.
You may be able to surpass it in resolution but you can't surpass it in terms of throughput.
Electrons are electrically charged, so a beam of electrons will interfere with itself. The only way around this is to have a very narrow beam, but that kills throughput.

Still, 1 MWh is a tiny fraction of the power those 100 wafers worth of chips will consume in their lifetime. So if we can reduce power consumption with smaller features, it's worth using more laser power.
I do understand a lot of that. I agree that many people have weird ideas about cumulative risk, in that they don't seem to believe in it. They seem to believe that the risk of a set of activities is the maximum rather than the sum.

And I do see how, if you've committed to being a smoker, reducing your risk and planning for the worst makes total sense. "I don't need to live past age 60" does sound a lot like passive suicidal ideation, and it may be worth speaking to a professional about it, but that's all I'll say on the matter, I don't want to be intrusive.

[I want to disclaim this as jawboning, I end up quiting smoking weed in this story, but I don't mean to imply anything by it and I understand quitting weed and quitting tobacco are worlds apart anyhow.]

I don't smoke tobacco anymore, but gosh I do love to smoke cannabis. I love the ritual of it, I love passing a bowl around with friends and listening to music, I love the texture of smoke, I love blowing smoke rings. It also helped to manage my anxiety. If I was having a panic attack, I could reliably terminate it by smoking. And it turned down the volume on the the anxious thoughts that I have bouncing around my brain.

Recently I've had episodes of terrible GI symptoms. Enough to briefly put me in the hospital. I'm not entirely sure, because many of the symptoms don't fit, but I think I've developed Cannaboid Hyperemesis Syndrome with an unusual presentation, the only cure for which is to quit using cannabis.

But I'm okay with it. By the time I came to this conclusion, I was making sure my will was in order, I just didn't know what was happening to me. So I was just happy that the best hypothesis seemed to be something curable.

So far, I haven't had an episode in a few days, the last episode I did have was milder. I'm starting to have more energy and feel like I just be thinking more clearly. The anxious thoughts that I smoke weed to treat are coming back strong, which has been difficult, but I'll find some other way to manage them.

I'll miss cannabis dearly, it served me well for a long time. I'm hoping I can smoke once a year at least. But man, I will do anything not to have an episode like that again.

Here's to the gift of life.

> At any rate, I continue to be unamused by how difficult it is for normal people to service their own Apple devices.

I am also a proponent of being able to self-repair (but can sort of see what risks Apple are minimizing by how they're doing it now). However, I would say most "normal" people are fine or would prefer to just go to Apple service centers. It is only with the more technologically-oriented communities where I see that preference. Of course this varies across communities across countries.
Every book I don’t like should be banned.

I can't imagine that what I think of as a machinist - a human who picks up parts and places them into machine tools and adjusts settings - is who makes parts for semiconductor manufacturing machines. I'm guessing the title has a lot more to do with CNC/automation these days?
Here in Sweden I can't recall such discussions. Large casualties from battles in Leningrad and Berlin involved millions of civilian deaths, but it mostly the actions made afterward when citizens surrender that get classified as a war crime and not the battle itself. Even explicit bombing of citizens, like The Blitz, are usually not refereed as a war crime even if it should fit the definition.

However, when discussing wars occurring in modern time, aerial and artillery bombardment that hit civilian targets do get refereed as war crime. Anti-personnel mines has also been added, which is seen as a war crime by most countries except for those who continue to use them.
