apophenia: spectacle at Web2.0 Expo... from my perspective
I blogged on this yesterday, but this is a post to read and share with college level and higher who are following Web 2.0 and specifically the use of backchannels.

14 driving rules for Interstates
I don’t mind driving, really I don’t. With my wonderful wife unable to do much driving over the past few years, I have done the bulk of it. This puts me on interstates with many other people. I am not a provincial writer, having driven and lived in many other states, so the statement that the section of the NY Thruway (I-90) between Syracuse and Rochester is about the worse stretch of road I have ever had the pleasure to drive. Not the condition of the road, but the number of people on it. It would be nice if it were 3 lanes, but no dice. Why is it so bad? I don’t know, but often the traffic comes to a stop for no apparent reason. After being stopped or going slow for a half hour, the traffic suddenly picks up to normal speed. Does the road get tired and suddenly close? Hard to say, but it happens on Sunday afternoons and evenings almost every time I am on that road. When this happens on other sections of road, there is a lane closed or a big wreck ahead, but that section of the Thruway, who knows?
Here are some rules of the Interstates I came up with yesterday while going 30 mph between Syracuse and Rochester.
1. If you have cruse control, USE IT. On a 65 mph road, Let’s all set it to 73 and forget it.
2. If a cop has someone stopped on the other side of the divided highway, you do not have to slow to below the speed limit, he is not going to stop what he is doing, cross lanes and come after you.
3. If a cop has someone stopped in your direction, try to pull over to the left and continue on your way. See rule 2.
4. If you plan on driving the speed limit, stay out of the passing lane.
5. If you plan on driving the speed limit stay to the right.
6. If you are going to pass, do so, sitting on someone’s rear fender is stupid. If you were going fast enough to get there, pass. See rule 1.
7. If you pass someone, and then pull in front of them, do not slow down, keep your same speed. See rule 1
8. The left lane is for passing. After you pass, get back over to the right. See rules 1, 4 & 5
9. If you are in the passing lane, and you see a long line of cars behind you, and no body in front of you perhaps you should get out of the passing lane.
10. On a three-lane road, the center lane is not the slow lane. See rule 7.
11. Pay attention to the signs. It is not nice to do a 3-lane dive to make your exit because you failed to pay attention to the exit ahead signs.
12. Turn off your bright lights, no need for them on the Interstate.
13. SUV drivers, see rule 12. Especially behind a car. Sometimes a person can read by your lights
14. No tailgating. Relax; we will all get there. Allow for stopping space between cars. Flicking your lights while I am passing someone is just annoying. Your time will come. See rules 1, 12, and 13.
That, at least is a good start. Please add your own
A couple people have added via Plurk comments:
15. If you are in the right lane, and there are no cars in the left, pull to the left to allow cars to enter the highway
16. As you enter the highway, there is a short section for you to accelerate before going into traffic, please use it for this

design the FAT
Have been Emailing back and fourth with my oldest son about our plans for the floating arm trebuchet. Giving ideas back and fourth. Here is one of his CAD drawings.
Having discussions as to the best height of the track and the distance between the weight and wheels. I wanted to have the wheels start on the track, but given some thought, that would make the mechanical advantage fairly low. With the wheels starting above, and the arm resting on another wheel on the frame, this will make the wheels arrive onto the track on a tangent, rather than slapping right down, it took me some thought and sketches to believe that it would work that way.
Watched the pumpkin chunkin championships last night on the Science Channel. These were great! I will never have the time or money to go to that level, but what the heck, small is good.
We can start doing some work on this in the next few weeks

Third Annual Educator Gift Exchange on Elfster
This is really so much fun and one of the highlights of last season. Join in the PLN madness and sign up on the Third Annual Holiday gift exchange - you sign up on this page and elfster "draws names" the end of this week - you send something to your person - usually things local to your area. It is a lot of fun. Thanks to Steve Dembo for doing this!
