This is the Internet identity crisis I live in.

Websites will just put me in the Latino (I'm assuming) bucket because my browser broadcasts Portuguese as a preferred language from a US location.

Not uncommon for me to receive emails half in English half in SPANISH.

Buying a $40k minivan can hinder your financial stability/freedom.

But NPR thinks a $2500 cargo bike is "pricey" and "cargo bikes are expensive"

Make that make sense!!

Many parents are now are forgoing minivans for greener alternatives: cargo bikes. They have been around for decades, but the advent of the electric bike motor has made them much more popular. n.pr/3WJyZn9

The Supernote eink tablets have a Rockchip RK3566 SoC and the battery can last up to two weeks with sporadic use.

HOW?? How do they sleep the device and keep it responsive when in use?

I understand deep sleep, but they must be sleeping the device during use

Just gonna throw it here because I'm seriously considering the Prusa Core One it as my new printer. ~$1,000 is the lowest you can get this printer in the US.

Prusa confirmed Amazon is an official seller. (shameless affiliate link)

*Parking is free*

Router template is printed but too late to make router noises around the house/shop.
