    For small amounts of text, another simple way is to paste it into the Run dialog (Winkey-R) and then copy it back out again. Works well for turning URLs into plain text and removin…

    Just FYI that the link to the page about the case against ultrasonic humidifiers is broken; it's missing the / after the domain. I tried leaving a comment on the page, but even aft…

    Middle schooler in the mid 90's, sitting in the backseat of the car while parents drove around town on errands. 2 meter ham radio antenna on the roof, with a packet radio modem and…
