Eve has been repaired after her fight with a buffalo and looks much better.  Now she just needs a bit of paint and it will be like nothing ever happened.

## A way of rounding corners

At work I have a project with a simple LCD display.  It includes a simple interface that includes rounded corners on the main menu.  While it doesn't effect what I am doing I was curious what algorithm they used to round the corners.  Most people use a variant the midpoint circle algorithm, including Bill Atkinson who made the rounded rectangles used on the original Macintosh computer.  This approach was a little different.  To round a corner, lines would be drawn between two points, starting with a vertical line, and then advancing finishing x point by one, and the decrementing the starting y point by one.  This is an old trick I remember seeing sometime in middle school.  You can do it on graph paper.  By drawing only straight lines you end up with a curve.  By moving only a single pixel, there are no unfilled areas and you end up with a rounded corner.
While this algorithm works, it's really inefficient.  Each new line only contributes a couple of pixels and the rest simply overlap.  Still, it does function.  Interesting way of solving this problem though.

The Emerald Dragon has now been running continuously for 365 days without a reboot.
Wingnut, Pokie and I went out for sushi this evening.

A prairie dog.  While Wingnut and I saw several prairie dogs on our trip they were not interested in having a look at us.  In years past when I have encountered prairie dogs I have found them to be very inquisitive.  Simply sitting down and being patient was enough for them to come out and wonder around.  Several times I had prairie dogs approach me, get close enough to sniff me a couple of times, and then go about their business.  This trip they won't let us get anywhere near them.  They would disappear into their holes and leave a couple up top in the distance to chirp at us.

While packing up camp at Bowman Lake I saw this deer wondering through the campsites.  Not exactly sure what it found but there was something in the fire pit it must have been eating.
