It’s a wonderful life

I wonder how many times the movie by this title will be shown this holiday season. While at the time of its release, the movie did not generate high attendance, it has since been called by many movie critics the best inspirational film of all time. I haven’t watched the movie this year, but I did see a marvelous play based on the story by a community theater group in our church.

Of course, the title begs the question: why is it a wonderful life? In the midst of all of life’s distress, financial problems, health issues, arguments, mistrust, the answer is the same today as it was for lead character George Bailey. It’s the relationships of friends and family that make life wonderful.

And yet, who can think how wonderful life is when everything in that life seems to turn against you.

“Be joyful always; pray continually; give thanks in all circumstances, for this is God’s will for you in Christ Jesus.” So was Paul’s commendation in 1 Thessalonians 5:16–18. Thankfulness, contemplation, joy: these three things are linked. It’s no surprise that psychological research confirms that a practice of gratitude leads to happier moods and less depression.

Try this simple exercise. Every day take a couple of minutes to list three things you’re grateful for: that benefit you and without which your life would be poorer. Consider the reasons for these good things. This won’t make the bad go away, but you will find that you’ll do a lot better at recognizing that it really is a wonderful life.

Christmas cookies

Decorating cookies

With Christmas approaching, we need cookies; lots of them. Karen had the girls over to help decorate some of them, which they are pleased to do. I think one of the reasons Karen likes to do it is because of the good times of baking with her grandmother that she remembers. It certainly is a memory building time for them all.

Painting with frosting

Audree is quite serious about it. Of course, when she made a little mistake she wasn’t shy about using her fingers to correct it and then licking the frosting off her fingers. I don’t think Karen saw her doing that :-).

Sprinkles... lots of sprinkles

Cortnie seemed to love sprinkles more than frosting, at least when I took this photo. She put on a base coat of sprinkles, then some frosting, and garnished it with more sprinkles.

From a mouse to a light pen

While I’m remembering things from 40 years ago I thought I’d write a little more about working on the PDP-1 computer. While debugging the mouse interface I wrote about previously, I added a small enhancement to the light pen. The original light pen simply set a hardware flag when the pen detected light as the point was being painted. The software had to continually poll the state of this hardware flag to check if the light pen had detected anything. This was inefficient. I simply added a few gates and some control circuitry to request an interrupt when the pen detected light. This took the polling instructions out of the display loop, and on a slow computer like the PDP-1 meant more points could be displayed before flicker set in.
