Do The Speed Cameras Help?

There has been a lot of back and forth on whether the speed cameras are a safety measure or a revenue generator.  Most people that support cameras say they're a safety measure, most that oppose them say they're simply revenue generators.  So who's right?

In my opinion they're both right.  No one can argue that they've brought in quite a bit of revenue since they were installed.  However, there seems to be some back and forth as to whether our highways are safer since they've been installed.  The Arizona Capitol Times has an article (membership may be required) that kind of presents both sides.

First it takes the DPS statistics (from an ASU study) for the loop 101 since the speed cameras were put in:

The ASU study, officials said, showed a 58 percent reduction in side-swipe crashes, a 71 percent reduction in single-vehicle crashes and a 40 percent reduction in accident-caused injuries as a result of speed cameras.

However, the statistics reported by DPS didn't include rear-end collisions that increased as much as 55% on the Loop 101 as reported from a 2007 study.  That looks pretty bad.  It seems that there are a lot of people slamming on the brakes when they see the speed cameras.  However, the article then gives the overall statistics:

Factoring in increases in rear-end collisions, accidents on the Loop 101 in Scottsdale decreased by 54 percent during the time speed cameras were in place.

So, is it a revenue generator or a safety measure?  I think it is both.  Yes, it's generating a lot of tickets but a 54% reduction in accidents is a pretty impressive number.  Besides, the revenue generated by them will probably trend downward as people become accustomed to the cameras and start driving the speed limit.

Overall, I think I'm OK with the speed cameras as long as they're not used as an excuse for not keeping sufficient DPS and other law enforcement officers patrolling our streets.  After all, a camera isn't near the deterrent as a law enforcement officer.

Insteon: Controller vs Responder

This entry is going to be more of a technical article.  If you're not planning on setting up scenes in an Insteon environment, this isn't for you.  If you are or like me, have been running into some confusion about what should be set up as a controller, what should be a responder, and what should be both.  Here's what I learned.

I've been using Insteon switches for a couple of years now and had set up a few scenes.  When adding a switch to a scene, you have the option of adding it as a controller, a responder, or both.  Not knowing the difference and wanting to cover my bases, I set all of my scenes to both.  Since my scenes were all timing type scenes (e.g. turn on night lights at sunset) it worked fine.  Then I added an 8 button keypad and started programming the buttons to control other lights.  The program for this, of course, is a scene.  Once again, I set every switch and button as both a controller and a responder.  Then I created a scene, specifically for my E…


I just finished reading The Agony and the Ecstasy by Irving Stone. It's a biographical novel of Michelangelo (you know, the famous sculptor/artist whose statue of David and the paintings in the Cistine Chapel are super famous) that gives a very interesting view of his life. It seems that while Michelangelo had a very productive life, it wasn't a very happy one.

One of the first things that I noticed about Stone's portrayel of Michelangelo is that he was obsessed with creating sculptures and a true perfectionist. For a large portion of his life (into his 60s it seems) his every action was calculated toward a goal of sculpting marble - either getting a commission or improving his talent (or both). Not only did he want to sculpt, he wanted his pieces to be as real as possible.

His obsession with carving perfect sculptures drove him to do endless studies of the human form. He even spent months sneaking into a morgue to dissect bodies so he could figure out how the body real…

Sonos Control with the Amazon Echo - How I did it

I've had my Amazon Echo for a year or so and one thing that I've wanted ever since I purchased it, is to be able to use voice commands to control my Sonos speakers.  I waited patiently (OK  not patiently) for Sonos skill to appear on the Echo but it still hasn't come.  I was encouraged when Sonos announced it was going to focus more on voice but still nothing.  Isn't there any way to control my Sonos with my Echo?

Yes - sort of.

WARNING: This post is not for the faint of heart because the solution is not trivial.

So, I found a project on github that uses another project on github combined with a custom skill on
the Echo via a web service hosted by AWS Lambda.  OK, that was the easy part.  I knew that going in.  That's why, initially, I waited.  There must be an elegant solution out there.  I searched and waited and searched again and waited again.  Finally I decided to give it a try.  If it worked it would be really cool.  If it didn't, well I'm no worse o…
