Several Completed Projects
The holiday went well. We and the children had much fun and were busy most of the time. We went swimming off Presque Isle in Lake Erie, boating on Pymatuning Lake, and spent a day at Kennywood Park. Makes me want to find similar attractions here around Raleigh, NC to entice our family to come down for a visit.

Automobile Control Research Opens Door To New Safety Features
NC State has developed computer vision programs that can keep a car in a lane on a highway. Dr. Wesley Snyder says they have gone even farther, "our program maintains an awareness of multiple lanes and traffic in those lanes.” (See the NC State Newsroom article linked in the title for more details)
How will traffic look in five to ten years if most of the cars we encounter on the road have such "auto pilot" controls or safety systems? I was tempted to think in idyllic terms, but I'm not so sure. To many drivers out there want to be ahead of everyone else. We see them passing the queue in the exit lane only to signal and squeeze/merge in at the last minutes just to be a few car lengths ahead of where they were before. I'm often tempted to write a traffic simulation. Then I think about what behavior I would need to model to make it a good predictor of actual traffic patterns. It always comes down to observing that lawfulness is inversely related to a selfishness or "self-importance" factor.
My computer traffic model dreams are almost always sparked by an interchange or intersection that seems to be poorly designed. Occasionally it is a tangent to answering how we as a driving community can exert social pressure upon badly behaved drivers to make them conform to driving laws and courtesy. Ah, a proverbial "tail-pipe" dream. Yes, sucking in the exhaust from the big belching behemoths called SUV's may contribute to these fanciful cogitations of cordial commuters.
Okay, NC State University, here is my challenge to you. Build a computer vision program that recognizes the cars and their license plates, combine it with observing the speed and noting unsafe driving actions of the other vehicles and add wireless Internet access to post these driving statistics to twitter. Then we can enjoy driving again as our cars with your computer vision identify hazardous drivers and give us a heads up display. It only needs one graphic, like the yellow first down line for football, just project the clearly visible words "stupid driver" onto the cars that have logged bad behaviors in twitter.
Then again perhaps yellow is not the best choice in this pine pollen drenched state.

Knitting Olympics : One Row Scarf and A Hat (Toque) to Match
Somehow I found myself caught up in the Olympic spirit while visiting The Yarn Harlot's site. I had browsed to her site to read the one row scarf pattern; then I ended up joining her 2010 Knitting Olympics.
--Interuption. I'll have to come back and finish this later.--
It is/was a knit-along of individuals. We selected our project to be a personal challenge to complete in 17 days. Start with cast on at the opening ceremony (swatches could be done as "training" before the opening of the Olympics) and then complete before the end of the closing ceremony on Feb 28, 2010. I chose a stocking hat and a simple one row scarf. I completed the hat but not so much the scarf. It was only half the length I had intended so I figure it as a gold in one event and no medal in in the second event.
So, I'll add one medal to this post. And a sincere Thank you to Stephanie and Franklin.

Parking in the wrong spot
I began my reply but then, like driving onto a patch of ice, my control of direction was stripped from me. I was researching lists of virtues and even found the scouts oath/promise and laws we teach our boys and girls. At some point in reading them I was convicted of failing to following what I was reading. I will recount my sliding path for you. Perhaps we can learn to spot the icy patches in our lives.
Decency has become less and less common. Good sense is no longer using it's middle name, common. Face it! We live in a "Me, now!" world where every one is taught to stand out and not be common.
Is it time to morn the death of these two family members? Which of their siblings still survive them?
Boy Scout Law:
A Scout is
trustworthy, loyal,
helpful, friendly,
courteous, kind,
obedient, cheerful,
thrifty, brave,
clean, and reverent.
The Girl Scout Law:
I will do my best to be
honest and fair,
friendly and helpful,
considerate and caring,
courageous and strong, and
responsible for what I say and do,
and to
respect myself and others,
respect authority,
use resources wisely,
make the world a better place, and
be a sister to every Girl Scout.
I was about to join in the lamenting of the poor parking practices of people I didn't know. It suddenly occurred to me I wasn't being friendly or kind, nor was I brave or helpful. The world we live in is far from perfect. We continually hear news of tragedy and horror. It is difficult to be brave and extend an invitation to be friendly to a stranger. It is easier to be courageous in a group, like in a social mixer for "bus stop neighbors" at a local café or bookstore.
A discussion of weather and the recent snow could lead to talking about narrow roads and limited parking. One could lament that there is barely enough space for three cars at the bus stop and that each driver would need to be good at parallel parking.
I don't often have to Parallel Park and I realized a short time ago my skills had nearly disappeared. I have since made an effort to practice and I can again triumphantly smile at the 6 inch gap between my tires and curb. I must remember, however, no to gloat about it because I do drive a Saturn and it is uncommonly well suited for those short parking spaces that are often the only ones available.
