HOoks and ladders :)

September 30, 2015


THat doesn’t really have anything to do with anything, but I did see a truck carrying an entire utility pole on it this morning. I also saw SVABBY2 again – but I think she’s found a different route. (THat’s the license of the VW driven by the lady who passed me on the right then […]

More khan fun

September 26, 2015


So I went back to Khan Academy to see what color they used for their layout,(and now I realize the answer to my question:   what shade of blue will be pretty but not too dark to see white text? is … right here on my blog…) I now, on this second day, can do […]

Badges and bells

September 25, 2015

The jury’s out …

September 23, 2015


or, actually, I haven’t had to report in for jury duty today or yesterday, so I’ve gotten to go to work, where it’s not crazy busy (in part because people knew I might not be here but mainly because of timing of tests, etc). So, no free hours to sit and doodle and speculate… I’m […]
