Submission + - Is your textbook studying you? (ruwenzori.net)

drkim writes: Shades of "Snow Crash"?

A number of schools have started using a program called CourseSmart, which uses e-book analytics to alert teachers if their students are studying the night before tests, rather than taking a long-haul approach to learning.

In addition to test scores, the CourseSmart algorithm assigns each student an “engagement index” which can determine not just if a student is studying, but also if they’re studying properly.

(BTW: We are holding a 'In Soviet Russia....' reference contest on this one, too.)

I'm afraid I do not know how she determined the sodium mass increase in the BEC, and I was not in her lab at that time.
She mentioned the mass increase in correspondence.
I just found it interesting because of E=mc^2 implications.

I am aware that, in the case of this article, the stated goal was to create matter; whereas at her lab, it was more of a byproduct.

how many of your 100 friends have the hardware even remotely capable of true 4K playback...needless to say, this is a solution without a problem...)

Not really an issue... You don't have to deliver 4K to everyone now; just like how Youtube lets you screen selective resolutions.

A few alternatives:
In the future (probably not that far off) more of your friends will have 4K.

The 4K still looks better in the sample than the native 1080, even though we were viewing at 1080.

Also in the future, you will have 4K at home (even if you don't now) and you will be able enjoy your memories @ higher resolution. Just like how we can enjoy TV shows shot on film at a higher resolution now, than TV audiences did back when they were first broadcast.

Finally, If you shoot in 4K, you can crop into the video to feature or eliminate things, without losing too much resolution.

...The cheat won. Not you.

Thank you for expressing that... something that was nagging me as I read the article and these comments.

I understand why people cheat in Vegas: they might walk away with real money.

I understand why athletes take steroids: million dollar contracts, fan adoration, groupies.

But, the point of online gaming is pure competition. It's anonymous, you don't even get the adoration of strangers. (and you're losing money, to boot!)

Cheating online just seems like bringing a pistol to a 1-on-1 basketball game, gunning down your opponent, shooting the ball through the hoop a couple of times; and then telling yourself what a great basketball player you are.

If you cheat, your score will always be a zero.
Those numbers in the corner don't mean anything...
