Comment From Degrading to De-Grading by Alfie Kohn (Score 1) 151

"You can tell a lot about a teacher's values and personality just by asking how he or she feels about giving grades. Some defend the practice, claiming that grades are necessary to "motivate" students. Many of these teachers actually seem to enjoy keeping intricate records of students' marks. Such teachers periodically warn students that they're "going to have to know this for the test" as a way of compelling them to pay attention or do the assigned readings -- and they may even use surprise quizzes for that purpose, keeping their grade books at the ready. Frankly, we ought to be worried for these teachers' students. In my experience, the most impressive teachers are those who despise the whole process of giving grades. Their aversion, as it turns out, is supported by solid evidence that raises questions about the very idea of traditional grading. ...

      A friend of mine likes to say that people don't resist change - they resist being changed. Even terrific ideas (like moving a school from a grade orientation to a learning orientation) are guaranteed to self-destruct if they are simply forced down people's throats. The first step for an administrator, therefore, is to open up a conversation - to spend perhaps a full year just encouraging people to think and talk about the effects of (and alternatives to) traditional grades. This can happen in individual classes, as teachers facilitate discussions about how students regard grades, as well as in evening meetings with parents, or on a website -- all with the help of relevant books, articles, speakers, videos, and visits to neighboring schools that are farther along in this journey. ..."

Comment Thanks for the insightful post on AI concerns (Score 1) 17

James P. Hogan wrote about some of these concerns in his 1979 sci-fi novel "The Two Faces of Tomorrow". Sadly the biggest taken-for-granted idea from his novel that now seems fantastical is that governments and engineers cared about AI safety over profit (i.e. the AI developers did not try to privatize most gains while socializing most costs and most risks). From the Goodreads blurb "Midway through the 21st century, an integrated global computer network manages much of the world's affairs. A proposed major software upgrade - an artificial intelligence - will give the system an unprecedented degree of independent decision-making, but serious questions are raised in regard to how much control can safely be given to a non-human intelligence. ..."

You raise a deep issue worthy of a lot of discussion when you say: " A post-scarcity economy is not necessarily an egalitarian one."

Your points also align with my sig: "The biggest challenge of the 21st century is the irony of technologies of abundance in the hands of those still thinking in terms of scarcity."

Comment Dogs and cats may react faster than crows? (Score 1) 27

Monkeys are slightly faster than humans at visual processing:
https://monkeys.alloftheanimal...
"The average [monkey] visual reaction time is around 200ms to 300ms, with a median of around 215ms. ... The mean human reaction time to touch, auditory, and visual stimuli is 150 milliseconds, 170 milliseconds, and 250 milliseconds, respectively."

But dogs are much faster:
https://humanbenchmark.me/test...
"The table below shows approximate response times to visual or tactile stimuli, drawn from published research: ...
Dog 60-100 ms Behavioral studies
Human (trained) 150-200 ms Cognitive research
Human (average) 250-300 ms Our test data"

So, if dogs are at least two to three times faster than monkeys, (I had heard elsewhere dogs are about seven times faster than humans), that means maybe dogs are even faster than crows?

I have to wonder about cat reaction time too? The table says cats are like twice as fast as dogs:
"Cat (domestic) 20-70 ms Behavioral studies"

Faster reaction time might help dogs and especially cats catch birds to eat them?

Anyway, so I think the implication in the quote from the article that avian brains are generally faster then mammal brains may not be well-supported given not enough species (both avian and mammalian) were compared?

Are you sure? There's so much money tied up in circular loans and IOUs based on potential profits that I'm not sure they are.

For example: NVidia invests billions into OpenAI and Anthropic, who then use that money to buy NVidia products. Has NVidia actually made any money, or does the "demand" for the product simply drive up the speculative stock price?

Why spend even more money on more equipment that you have to store and maintain, and buy increasingly expensive fuel for, when you can dual purpose what you already have?

That's assuming you can even get fuel of course. When Sandy hit (last big hurricane in this area) most of the gas stations around here were inoperable for the first day or two because - you'll never believe this - but fuel pumps ALSO need electricity and there weren't enough generators rentals to go around. The stations that were operating over the next few days quickly ran out because the depot infrastructure, located on the shoreline, was damaged.

So sure, all you need is a generator, and an entire evening to wait in line for your rationed fuel hoping they don't run out by the time you get to the pump. So easy and much more convenient than just running an extension cord to the EV in your garage, which also runs silently, indoors, all night if you want.

If you want to go full prepper mode buy some solar panels and lay them out in the driveway or lawn. Even a kw or two worth (about 4-7 panels) would be able to easily cover your daily emergency needs with an EV battery to store it in.

The run time will obviously depend on the size of the battery, which will likely be available in at least two sizes. I'm willing to bet you can also set reserve limits so the truck doesn't completely discharge itself, and that further limits the run time.

Battery capacity has yet to be announced though.

All that said, I'd say at least 30kwh which will keep most homes running 2-3 days without any change in usage habits. With some very conscientious usage you can probably get a week out of it.
