ELD or electronic logging devices, are invading the privacy of truckers regarding how they spend their time.

At 8:00 she explains "We get really excited about technology holding forth a promise to solve social and economic problems - it almost universally doesn't, it just moves the problem a little bit. When you have a problem with deeper roots than technology, the technology ends up being just a Band-Aid."

Can you afford to retire? | 4% Rule Explained

https://youtu.be/cmSxFo2Pz-o

2:12 "Once you have saved 25 x your annual retirement expenses, you should be able to retire with the reasonable certainty you'd be able to survive on your savings until death."

He goes through the numbers pointing out that, even with inflation and occasional devastating drops in the investment market, you should be able to live off your savings.

He also points out the huge impact of a single purchase early in retirement on your eventual net worth; in his example buying a $35000 car early in retirement decreases the net worth by $200,000 in your nineties.

The remedy, of course, is to work in retirement just enough to afford any splurges beyond your regular expenses.

English words adopted into Korean language

I found this surprising, and insightful. I was sure it would be easy for native Korean speakers to avoid English loan words. It's odd that they didn't realize how many loan words they were using, routinely.

How does a camera gimbal stabilizer know when you're panning versus drifting/shaking to the side?

A handheld  3-axis gimbal stabilizer can eliminate  vibrations enabling smooth smartphone shooting through the three-gyroscope chip with self-adaptive 3-Axis mixing which applies a correction based on proportional, integral, and derivative terms (PID)* an algorithm that controls the three motors to achieve automatic stability and balance in the shooting process.

In practical terms, [such a controller]  automatically applies accurate and responsive correction to a control function. An everyday example is the cruise control on a vehicle; where external influences such as gradients (hills) would cause speed changes, and the driver has the ability to alter the desired set speed. The PID algorithm restores the actual speed to the desired speed in the optimal way, without delay or overshoot, by controlling the power output of the vehicle's engine.

Making a house extremely airtight by spraying a mist of caulk into a pressurized house seals all the tiny cracks and leaks, as they demonstrate here. That reduces the chance of mold, water vapor, and insects entering the walls.

Studies: Crows count, chimps know when they're right - CNN

https://www.cnn.com/2015/06/10/us/chimpanzee-crow-intelligence-studies/index.html

I'd heard about crows counting how many hunters were behind a hunting blind, (mentioned in this article) but I wondered how they had measured the change in behavior when the crows knew the hunters had gone. These experiments seem more sophisticated than that at proving how crows and chimpanzees think. Metacognition..is knowing that you know something...They gave three chimps computerized memory tests and rewarded them with food for correct answers, but they built in some hitches to tease out signs of metacognition..The reward appeared at a place away from the test area, and when the chimps got an answer right, a sound alerted them that the food was going to appear -- with a slight delay -- at the distant spot. They had to hustle to get to the other station before the food popped out, or it would disappear, or go down the drain, so to speak.
But that alerting sound was delayed, too. The apes barely had enough of a heads up to make it to the reward station in time to catch the food before it vanished.
After a while, the chimps appeared to get a sense for when they got an answer right and when they didn't. And when they did, they often darted for the food station ahead of that tardy sound signal.
If the monkeys got an answer wrong, more often than not, they sat things out. After all, when you've bombed, why go to the trouble?.
