no no... please buy a new pixel 9/10/11.

it takes slightly better pictures and it only weighs 50% more than your current one. oh did we mention it gets a full day of battery... yeah, apparently that's notable again as it was 15 years ago.

the in-screen fingerprint sensor kinda sucks, but don't worry, you'll eventually forget the rear sensor was flawless for years.

Stuff like this seems inevitable to me, but various forms of 3d printing buildings whether out of concrete or other dirt+binder systems have been being experimented with for at least 10 years if not 20. Who knows if they'll ever achieve value parity with standard methods.

Though "standard methods" aren't an entirely static target either. Like i was watching some pumped concrete building of a high-ish rise building in Miami some months back and, while not robotic... it certainly included a lot of labor saving automation.

Dude, they may be hassling kids in the rural areas, but in cities on the East Coast youths (i.e 12 to 35yos) ride unregistered gas dirt bikes and ATVs with total impunity through and around traffic and have for at least a decade. Both as transportation and as cultural expression.

this article is from Cleveland area this week , but it's the same in Philadelphia and DC suburbs at least.

Like with so many other things the government and cops will hassle the relatively law abiding with all sorts of technical and clerical bullshit, but ignore the gross violators of laws that have been on the books for years.

Most of the districts that COULD do that DID do that back in the 20th century. But there were arguments that the "slower kids" (C and D) above were just being "warehoused" and later "the soft bigotry of low expectations" and all that. Which led to general increased focus on the C and D kids and just leave the A and B as "eh. they'll be fine with whatever."

And the argument then further became that tracking is inherently discriminatory and that it shouldn't be done at all. Which is e.g. San Francisco removed 8th grade algebra back in 2014. because it wouldn't be "fair" to let some kids "get ahead".
(https://thevoicesf.org/san-francisco-flunks-the-algebra-once-again/ ). It's been a fight w/ parents ever since but the district is still winning.

Similarly in NYC they dropped admission tests for most of the public middle schools that had them a few years ago. And the magnet high schools (like Stuyvesant and Bronx Science, which probably have the smartest student bodies in the country) are under constant attack.

Yes, and no. I agree that everyone should be taught to read (with phonics and then for comprehension), as early as possible because it is a useful and empowering tool for accessing information and bootstrapping further learning.

However, there is a large variation in innate capacity to learn to read at all. To pick an arbitrary line: the large majority of 4 year olds won't be able to understand a YA level novel no matter how early or how intensively you started training them. But some of them will.
The real problem is that , again due to innate capacity, even some non-trivial level of 14 year olds will not be able to really understand that same YA novel.

And this difference in capacity is not obvious to most because of a lot of sorting in society. (e.g. the kind of people who even look at /., let alone comment, are people who to some degree are reading and writing "for fun" and they very likely work with and interact with other people who do that sort of thing. and it's easy to think that capacity and tendency is only a matter of effort or choice. but it's not only that. (even w/o getting into discussion of "clinical" dyslexia ) )

on ROI:
if you assume all the kids are relevantly the same EXCEPT for instruction, then yes.

but in reality, to use electric car analogy, the "quick" people have more total capacity and higher charging rate capability than the lower performers. say, modern Model S vs Nissan Leaf. If optimizing for time ... 15 minutes on a DC fast charger will transfer more miles to the modem S than the Leaf.

But the US system hasn't, lately, focused on the total miles of charge in the fleet (the class/school), but rather to minimize the number of cats with less than 50 miles available range. (along with the strong assertion that there are no leafs or model S-es only a fleet of idk Ioniq 5s )

(the analogy only goes so far since instruction is one to many, not one to one like car charging ... and other differences, but it works for this narrow example)

"spaced repetition with active recall" (which is an extended version of what you're saying) is basically a given at this point as the way to learn (and keep) stuff in your brain, afaik.

If you only have a single 7th grade class, then you can't do tracking (in the basic way), but let's say you have 2 7th grade classes. 48 students total.
Further let's say you straight rank them by "ability" (prev grades, IQ, whatever) into 4 groups of 12 A, B, C, D.

You can then choose to either "balance" the classes (e.g. each class has 6 from each group) or you can track them. so the fast class is all A and B and the slower class is C and D.

In the balanced model, both classes proceed at about the pace of about the C group. The B group are under challenged, the A group are bored.

In the tracked version the faster class goes at ~ B+ pace. The slower class goes at D+ pace. In both cases more people go at a speed that's closer to their level of ability. The only arguments against this (afaik)

That's the most basic model but there are others where maybe for a few hours every other day the slower kids get extra tutoring on the basics, the smart kids do "enriched" stuff. and the medium kids do medium enriched stuff.
(though this version kinda sucks for the remedial kids... i guess )

"tracking" is the solution to that (or at least minimizes the impact)... e.g remedial, normal, and honors classes... magnet schools, etc.

but the focus in the US education thinking and efforts for the last 30+ years has been more "closing achievement gaps" between ethnic groups rather than increasing average gains.... because "equity".

so that's exacerbated the focus on bringing up the bottom performers in general and ignoring the top.

whether it's in class or at home there's no way afaict to learn math or anything that requires selecting and applying algorithms to a problem to solve it without practice.

however in these days of video, I could see asigning kids to watch the lecture at home... and then do the practice in class.
ofc most of the kids still wouldn't... but there's little advantage, imo , to having a teacher stand there and give a live chalk talk for 30 min over a video. and watching videos as hw seems easier ...

TFA has a paragraph buried in the middle that suggests it's more complicated than that..

it is not your imagination. I think it's that this article like many of its ilk are basically a summary of a press release or a few competing ones and a quick smattering of context from a web search, but without much independent further investigation.

Probably it's a throughput and tight turnaround. Definitely nothing like old school Scientific American or Nat Geo articles, but those were magazines on monthly scale and even economist, etc were weekly whereas even these secondary articles are just a few hours after "breaking news"

LOL. took me a few beats. nice!

the sentiment against the UK sounds less off the wall than it did then too.

Heh. came here just to say this.
But only a change fee seems too generous. Why not also have to pay a monthly fee for any color other than beige as well?

Tru tru.
