I've just finished teaching week four of the amazing Clarion Science Fiction Writers' Workshop at UC San Diego; in addition to spending a week working closely with some very talented writers, I came up with a new and cheap way to make astounding cold-brew coffee.
I bought a $10 "nut-milk" bag and a plastic pitcher. Every night before bed, I ground up about 15 Aeropress scoops' (570 ml) worth of espresso roast coffee -- the $20 Krups grinder is fine for this, though I wouldn't use it with an actual espresso machine -- leaving the beans coarse. I filled the bag with the grind, put it in the bottom of the empty pitcher like a huge tea-bag, and topped up the pitcher with tap water (distilled water would have been better -- fewer dissolved solids means that it'll absorb more of the coffee solids, but that's not a huge difference). I wedged the top of the bag between the lid and the pitcher and stuck it in the fridge overnight.
In the morning, I took the bag out of the pitcher and gave it a good squeeze to get the liquor out of the mush inside. Add water to the pitcher to fill to the brim and voila, amazing cold-brew. You can dilute it 1:1 or even further.
Cleanup was easy: invert the bag over a trashcan or garbage disposal, rinse off the bag, and you're ready to go.
This produced very, very good coffee concentrate, with only a little grit settled into the bottom 3mm of the pitcher (easy to avoid). It may just be the cheapest and easiest cold-brewing method I've yet tried.

John Deere is notorious for arguing that farmers who buy its tractors actually “license” them because Deere still owns the copyright to the tractors’ software; in 2015, the US Copyright Office affirmed that farmers were allowed to jailbreak their tractors to effect repairs and modifications.

All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady.

The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
