Comment Re:A face shield is for eye protection (Score 1) 112

Agreed. It looks like the consensus is that for regular people out and about the shields are probably not a big deal. But for those of us in retail or food service jobs they could potentially increase the protection for the wearer significantly. https://institute.global/polic...

Comment Re: For anyone wondering how Robinhood makes money (Score 5, Informative) 147

From the article: 'That’s because it makes money through a complex practice known as “payment for order flow.” Each time a Robinhood customer trades, Wall Street firms actually buy or sell the shares and determine what price the customer gets. These firms pay Robinhood for the right to do this, because they then engage in a form of arbitrage by trying to buy or sell the stock for a profit over what they give the Robinhood customer.'

Comment Credit Freeze Pin's not random (Score 1) 401

As an example of more (probably) sloppy security, I just put a freeze on my credit with Equifax (and the others). Equifax gives you a pin number that you need to unfreeze your credit at a later date. Imagine my surprise when my pin is almost exactly the same as the one they issued my wife. It appears that they use sequential pin numbers for each freeze. Either that or it is generated using our personal info which would make it reversible I imagine. Seems to me that the pin should be random or at least pseudo random. At least Experian allowed me to choose my own pin, which I let keepass pick.

Comment A hidden benefit (transparent assignments) (Score 1) 143

I think that one benefit to personalized learning that is often overlooked is the transparent and clear assignments.

My high schooler was lost in his math and English classes and it was impossible for us as parents to help him at home. The teachers did not use the on-line system at their disposal to share upcoming assignments and due dates. Assignments were only posted on line after the due date and with no information as to what the assignment was.

Upon moving him into on-line classes for English and Math, he is now learning the material, able to know exactly what is expected, and is getting much better grades. It is unfortunate that in our case the solution was to remove him from the classroom and all the benefits having a teacher brings. I continually try to get my student's teachers to make assignments available on-line but with amazingly limited success.

Comment Re:windturbines are not the solution (Score 1) 190

You are correct that individual wind/solar farms are stochastic. However, connect enough of those stochastic systems together, diversify their sources, spread them over a wide enough area and throw in some energy storage and your individually stochastic generators become pretty deterministic.
