One of my recurring ones is: keep Resource Room better updated. Welp, I at least knocked one piece of that off the list: I uploaded “Drill Bits” so that anybody can pull it down now. “Drill Bits” was a product I sold when I did that on the website. It’s a rather vast collection of […]

I read on the discussion that Udacity doesn’t offer certificates for its “visualizing algebra” course now… so I wonder if it’s going to just … fade … away.   Sad.   This online stuff is new enough that in my not so humble opinion, it’s worth exploring different variations…      It’s Friday 🙂

… but no, things didn’t improve.  However, my computer at work has not been tainted with updates and … things seem to be actually working.   I even got things like answers from StackOverflow — though the advice was to update everything and … no, that doesn’t work… and my subsequent question didn’t get answers.  […]
