Have you ever visited a website and wanted to see the images displayed larger? That happens to me all the time, and it isn't always easy to make that happen. On occasion, I sift through the source code, use Ctrl + F to search for the image, copy the image source address and paste it into a new window in order to see the image at its full-size glory.

I enjoyed using my terminal's green-on-black color scheme for many years. It is reminiscent of the DEC VT100/220 terminals that I used in college.

I thought my time in Australia would have given me enough linguistic power, but, alas, a lot went over my head. There was more than the usual "soccer is football" or "trunk is a boot" sort of confusion. read more
