New to me but not to others because I still don't have USB 3.0 female ports -- or a controller to run them at USB 3.0 spec... USB 3.0 may cause interference that affects the 2.4 GHz range. I think it's related to the data lines?

No wonder they moved to USB-C already or stuck with USB 2.x and USB 3.x mini-B never really hit wide adoption?

I found out that Google Plus may have once required people to use their real names, and Facebook may too?

Considering that they didn't ask for my birth certificate, I just took it as "real sounding name." Guess I wasn't popular enough to ever be banned.

This KYC (know your customer) crap could be getting out of hand. It made sense for situations where monetary transactions were involved and now that you can buy shit on FB, I suppose they have an excuse for doing that there. But honestly, the alternative is just don't permit people who don't provide kyc info to buy or sell. Simple. But nooooo. Why pass up a perfectly good excuse to bleed you for even more personal information.

I agree in that there are variables in the transaction that might warrant throwing up a red flag. For instance, Bubba is buying a pound of ammonium nitrate from the seed and feed to clear some tree stumps out of his field versus Akmed who is trying to buy a tractor trailer load of the same thing and he doesn't own any property much less farm land requiring clearing.

That'd be awesome, then there'd always be lines for filling up on the same side of the pumps!

(this is why they aren't)

KMFJD posted a "smarter every day" video which has just cost me an hour following their videos...anywho,
here is one about turning gravity into light.
https://www.youtube.com/watch?v=Jsc-pQIMxt8

Question, at about 5:40 he says the the led has a voltage limit and when it is reached, it won't let the generator turn any faster. Is the generator acting like a brake for the rubber band that is turning it so the rocks can't fall at a faster speed?

Curious minds want to know.

That statement is misleading because in general semi diode current increases as exponential of voltage, but in practice they'll burn up at some point. Frankly I have no idea what he really means by it since presumably the device isn't burning up the led's.

In any case, yes the generator is acting like a brake. The consistent gravitational force is met via newton's law with the braking force/resistance of the electromagnetic coils inside the motor, and the electric force/current that turns into is what's used to power the led.

The 2nd paragraph makes sense. Thanks.

The world is burning. Everything is more flammable now to the extent that while 30 years ago you had more than 15 minutes to escape a burning house, today, you only have 3-4 minutes. And it doesn't say this but the gases are probably more toxic too.

In the event of a house fire, residents have only one option: Get out, and get out quickly. That was the conclusion of a 2016 study conducted by Underwriters Laboratories in Chicago, which determined that occupants have only three or four minutes to escape a burning house. This is a marked decrease from 30 years ago, when you may have had about 17 minutes to escape from a similar fire.

The report posted at Today.com attributed the difference to the fact that more synthetic materials are being used in today's furniture and fabrics. "The backing of your carpet is synthetic, your drapes are synthetic, the couch, the pillows are synthetic," explained John Drengenberg, consumer safety director for UL. "They burn hotter and faster than natural materials do."

On the other hand, how do fires start?

  • The American Home Furnishings Alliance told NBC News that it supports a federal flammability standard for upholstered furniture, but only if changes are safe, effective, and affordable.
  • In the 1970s, the Alliance said, upholstered furniture made in the US transitioned to polyurethane foam for cushions. Foam is more durable, affordable, and hypoallergenic.
  • The Alliance said that a vast majority of home fires are traced to upholstered furniture being ignited by a smoldering source.

I like the prevent the fire from happening in the first place tactic. I have class A, B, C fire extinguishers all around the house. Of course stats say that a lot of fires start between I think 11PM to 6 AM.
