My wife seems to have purchased a very controlling bottle of wine…

Finally read Robert MacFarlane’s “Is a river alive?”, beautiful, pensive disturbing, and calming. A lovely read for my commute and on weekend mornings. Although I must confess, it didn’t quite reach the (metaphorical) depths of Underland. Next up, Robin Wall Kimmerer’s “Gathering moss.” #booksky

Take a break from being depressed that everything you love is being destroyed by slop for a moment and let me tell you about the beautiful symbiotic relationship between graffiti writers, train yard workers, and model train enthusiasts.

And you definitely don't want to use a high-powered 532nm green laser, because it can permanently burn and disable digital camera CMOS or CCD sensors. Green light is absorbed at a very high efficiency by these electronic sensors, meaning concentrated beams easily melt or overload the pixel array.

They removed CD/DVD drives from PCs. -Made physical media harder to buy and use. -Removed expandable storage from phones. -Pushed us into streaming subscriptions. -Made always-online normal. -Made unlimited internet necessary. -Slowly raised the price of everything. Ownership quietly became renting.

To communicate with submarines, the navy blasts low frequency sound through the oceans at deafening volumes. They know that's whats driving the whales out of the water, but they hide what they're doing under "top secret" classifications.
