I changed one line of code from pinMode(pirSensor, INPUT) to pinMode(pirSensor, INPUT_PULLUP) activating the internal pull up resistor on AtMega328 chip, making the PIR sensor properly turn on and off. Well that was easy.

Spent a lot of time scratching my head over it. Sure beats having to solder another doggone pull up resistor. Now the lights shut off when I leave my bedroom saving energy.

Facebook Launches “Donate” Button For Non-Profits That Also Collects Billing Info For Itself

I've wondered why Facebook is so aggressive at promoting it's donation program. While Facebook does not charge anything for donations to chartiable contributions, they do keep your credit card to make it easier to solicit you later on for ad sales and game add-ons. They are big, so they have good terms with credit card companies, so they get a low rate, so the transaction to cheriable organization doesn't cost them much.

He Predicted The 2016 Fake News Crisis. Now He’s Worried About An Information Apocalypse.

"Still, Ovadya and others warn that the next few years could be rocky. Despite some pledges for reform, he feels the platforms are still governed by the wrong, sensationalist incentives, where clickbait and lower-quality content is rewarded with more attention. "That's a hard nut to crack in general, and when you combine it with a system like Facebook, which is a content accelerator, it becomes very dangerous."

This Is What It’s Like To Not Own A Smartphone In 2018

I didn't own a smartphone until 2014, when with work it became more essential to check emails for work. With my dumb phone, I would have to walk down to the library if I wanted to read an email. I guess I could use the minimal web browser in my dumb phone, but for most bigger things I had to go to the library. But by 2014, with StraightTalk you could get a Smartphone for under $45 a month if you bought time in 3 or 6 month blocks, and the phones were cheap, so I switched on over to a Smartphone. Not having an Internet at home (much less in the wilderness), having a smartphone really is a nice thing.

The Magnetic Field Is Shifting. The Poles May Flip. This Could Get Bad.

"The Earth’s magnetic field protects our planet from dangerous solar and cosmic rays, like a giant shield. As the poles switch places (or try to), that shield is weakened; scientists estimate that it could waste away to as little as a tenth of its usual force. The shield could be compromised for centuries while the poles move, allowing malevolent radiation closer to the surface of the planet for that whole time. Already, changes within the Earth have weakened the field over the South Atlantic so much that satellites exposed to the resulting radiation have experienced memory failure."
