Another good read for those trying to understand python metaclasses

Tesla Model S (265 mile range) battery swap vs Audi A8L (666.4 mile range) refueling. Admire Tesla and Musk, but this comparison reminds me of the type of comparison that gets Redmond their bad press.

One Day....

Captain Stooks aboard S/V Swallow. Soon to be #sailing the seven #seas. Spent the afternoon aboard, working on some of the sparkling. Brought back so many good memories from last year. More to come? #onABoat #boat #sealife #boats #sail #marina #shipyard #ship #yard (at Strugglefest)

My least favorite people in the world are the people with the little bluetooth headset who have loud conversations in public places. Yes sir, you are super important and the entire world is your office." Bluetooth gave the self-important office worker permission to have loud, annoying conversations in public. Sure, hands-free conversations are important to a lot of busy people, and a safe way to talk and drive. But, at some point between early adoption and over-before-it's-cool promulgation, those little blue ear pieces became a damning signal of an inconsiderate, work-obsessed person whom nobody wants to be around.
