I read a pre-print of a paper, The origin and early evolution of arthropods,
I accumulated a quart jar of US coins, legal tender for all debts public and private.
I turned the coins into paper currency at a “Coinstar” vending machine in a Safeway grocery store.
I decided to upgrade my OpenWrt One WiFi router.
