Thus 5x3 becomes 5x5x5 or 3x3x3x3x3 instead of "STFU and memorize your times tables."

I'm fine with the repeated addition. My objection is the OR in your statement. Apparently not. The question was 5x3 and the kid wrote 5+5+5=15 and got marked wrong with no explanation because the teacher wanted 3+3+3+3+3=15. So I guess that you would have had a 50% chance of being marked wrong on a 2nd grade arithmatic worksheet as well, as absurd as that is. Correct answer notwithstanding.

BTW, that's not at all new. We covered multiplication that way in the 3rd grade back in 1975. Memorizing the table was just to make it quicker. I quickly "discovered" the commutative property while looking at the multiplication table and cut my memorization load in half. The part that confused the father was why is 5x3 = 5+5+5=15 "wrong".

As for 37+55, we decomposed that in the '70s as well, but I soon decided the easier decomposition was 37+55= 87+5 = 90+2=92. So I would say that meme was just someone wanting to complain. Of course the "old way" ends up in 30+50+10+2 anyway.

Shut up and memorize was not in practice during the education of the parents of today's students.

So many logical fallacies in there, buddy.

If you want these things, then you will pay for a good public education.

This presumes that "good public education" is being funded with tax money. It is, conclusively, not. It has in fact been getting significantly worse - which is why people are opting out of it.

Do you want educated neighbors?

No formal education is, in most cases, better than bad formal education. I'd rather my neighbors not be stupid but think they know something, which is what the last 50 years has produced.

Who you can hire for your business? Who will have enough income to purchase your product? Who will be employed and can adapt their skills to a rapidly changing environment?

There's no evidence that education can elevate someone over their inborn genetic potential. You've either got the building blocks for intelligence or you don't. See also the last several centuries of 3rd world "enrichment" that's been carried out by one means or another - education, charity, etc. - of places like India and Africa. I'm sure you can look up average IQs if it's of interest.

Who will be employed and can adapt their skills to a rapidly changing environment?

I can hire a home schooled person, then? Because this criteria definitely doesn't fit your average public schooled individual.

Who will know how to make healthy choices for themselves and for their neighbors (you)?

Yes, the Food Pyramid, D.A.R.E., and "Sex Ed" had a fantastic impact on society's wellness trajectory - I'm sure we can all agree on that, right? (This is sarcasm.)

Who will carefully consider and thinking critically about public issues and use that knowledge when they vote?

OK, now I know you were being facetious. There's no way you're talking about state schooled kids here.

This is the wrong approach. Perhaps it'd have been accepted earlier, but they've shot themselves in the foot due to their inaction over the grooming pedophilia groups that were operating with impunity - and seemingly, protection! - on their platform. It was brought to their attention repeatedly, publicly, and they did all the wrong things and did not address the issue.

Fuck them.

The NVidia cloud isn't new. It's been around for 3-4 years now at this point and seems pretty mature. It also works far better than Stadia ever dreamed.

I was able to play through multiple games I'd purchased specifically for the purposes of playing them on Nvidia Now, because I didn't have a gaming computer but wanted to complete the titles (Cyberpunk 2077 and Mechwarrior 5). The 'free' tier was irritating with wait times, but was playable. The higher tiers were far better and other than a rare ISP-related stutter (at 80ms or so, no less), and it ran great.

This means it's definitely playable at the 30-40ms that a person would get on Starlink (which I later got, and tested, and it worked even better). $10/mo for a couple months seemed like a pretty fair price for something that enables gaming. It wasn't a great experience on hotel wireless, but that's barely ever usable for much more than email. Keep in mind, I'm not a 'gaming snob' focused on FPS or graphics so much as the gameplay and experience, so I'm sure there's some aspect there that I overlooked, but $30-50 for a winter of gaming beats $500+ for the computer to do so. I just used a Macbook Air.

And it doesn't work the way you think it does. It's basically like, from what I can tell, RDP specialized for gaming. You can play it from anything that can support basic framerates and uses remote rendering. The game dispatches and loads onto a 'thin' Windows client of some sort, and it integrates with GoG, Steam, and a number of other gaming services.

Math is hard.

If a substantial percentage of the population is vaccinated, the likelihood of being exposed to measles is very low, so the 3% who might contract it if exposed have a good chance of not being exposed. This also doesn't account for whether the severity of the infection will be different for those 3% if they have been vaccinated.

It was my example. It came from a photograph of the worksheet posted to Reddit by the child's father, who was wondering why the answer was 'wrong'.

Surely you don't expect the 2nd graders to start on Clifford algebras any time soon. They need to learn to walk before they run. Note that by the time you're multiplying vectors and matrices the process involved is sufficiently different from multiplying real numbers that not being commutative is not going to be an issue. I recall my high school math teacher demonstrating non-commutative multiplication. I was not confused in spite of having figured out the commutative nature of simple multiplication in elementary school.

The speech to text can be nice (even if my phone keeps writing "free cat" when I say FreeCAD), but it clearly has significant limitations. I still can't even guess why my phone can respond to "flashlight on" but fails at "flashlight off".

It's also amazing that it's possible to draw a metal wire thinner than a human hair and even more amazing that it's possible to drill a neat hold through it's width without breaking it, but I really don't have much use for that day to day.

As for image generation, quick, how many fingers am I holding up on my right hand? (hint: not 6).

Comment Re:Imagine if the COVID vaccine cultists (Score 3, Insightful) 305

The thing is, it wasn't lying. First there wasn't much evidence for the myocarditis, then it was confounded evidence. Did the kid get myocarditis from the vaccine itself, or was it from the beginning of a COVID infection aborted because the immune system was already actively reacting to spike protein at the time.

Of course, over-arching all of that, COVID causes myocarditis too, and often worse so it wasn't all that clear if mild myocarditis from the vaccine would even matter. Try explaining that to people ready to eat horse paste and unsure why people are laughing at Trump's suggestion to inject bleach.

Then there's a question of how much of the distortion came from scientists and how much from journalists (mis-)quoting them?

Now that the data is in, we can see that there is some possibility of mild myocarditis from the vaccine.

The thing about science is that as more data comes in, theories change and so actions suggested by those theories also change. In emergent situations such as the COVID pandemic, data and change can come fast.

Perhaps a sports analogy. After the first baseball game of the year, plenty of batters have an average of 1.000 for the year. Plenty have .000 for the year. That will change a LOT in the next day. By the end of the season, batting averages don't move that much in a single game.
