Wednesday, November 17

Today is Wednesday of WEEK 13 of the class. If you have not turned in your Week 12 Storybook assignment yet, you may still do that for partial credit. Wednesday morning, until noon, is the grace period if you forgot to do any of the assignments that were due on Tuesday. The regular Week 13 schedule applies today and also on Thursday; see the Tuesday announcements for how Thanksgiving Break works all of next week.

Storybook stack. There are still quite a few assignments in the Storybook stack. If you turned in your assignment by 10PM on Sunday, you should have comments back from me now. Assignments turned in later on Sunday or on Monday or Tuesday are probably still in the stack. You can check the contents of the stack to make sure I have received your assignment.

Mix and match points. (repeat announcement) Now that there are less than three weeks of the semester left, you might want to plan to do some "mix and match" in terms of just which assignments you want to complete this semester to get the points you need for the grade you want to get: 410 points for an A, 360 points for a B, or 320 points for a C. So, based on the assignments you enjoy most/least in the class, you can certainly skip some assignments, provided that you end up with the points you need at the end. My only recommendation is that you do this cautiously. You don't want to skip so many assignments that you end up not getting the points you need for your desired grade.

November 17: Birth of "The Mouse." On November 17 in the year 1970, computer pioneer Douglas Engelbart was granted a patent for what would become the "mouse" interface for supplying data, manually, to a computer. In the patent application, he described the wooden box with its two metal wheels as an "X-Y position indicator for a display system," although he nicknamed it the "mouse" because it had a tail coming out one end that connected it to the computer system. Dr. Engelbart has not profited from his invention because the patent ran out in 1987, before the widespread use of personal computers made the mouse ubiquitous (although I remember first seeing someone using a mouse in the summer of 1984). You can read more about the history of the mouse in this Wikipedia article, which is also the source for this image, which shows Dr. Engelbart's mouse, circa 1970:
