Global Warming?

Global warming has become quite an issue lately. Temperatures are rising but that seems to be just about all anybody can prove. There are so many slogans and sound bites on global warming that it's hard to tell what's really going on. Well, here's my opinion:

The problem with global warming is that it is a very complex issue that too many people are trying to oversimplify (including Al Gore). The real "inconvenient truth" is that we simply don't know enough to make some of the judgements that are being made.

Is global warming happening? Yes. I doubt you'll really find anyone knowledgable on the subject that doesn't think it's happening. That's the easy question.

Are humans causing it? Nobody really knows. There is some evidence that human activity plays a part in it. However, the data doesn't show the extent. Are we causing 90% of global warming or 1%. We simply don't know. There isn't enough data.

Is catastrophic climate change on the horizon? Again, we don't know. The complex climate models that everybody seems to think are accurate predictors aren't. The fact is that these climate predictors can't take 1990 data and accurately predict 2000 weather/climate. Yet everybody seems to trust that it's accurate at predicting the climate for 2050. Once again, we need more accurate information.

The real problem with global warming is that we really don't know anything concrete apart from the fact that it's happening. In 1975, Newsweek published an article that claimed global COOLING was going to cause all sorts of environmental disasters. I guess that scare was short lived.

My personal opinion is that the pollutants/greenhouse gases that we are pumping into the atmosphere are, at best, a health hazard to all those living in large cities (asthma, respiratory infections, shorter lifespans, etc) and at worst, an enviromental disaster. So whether or not we're causing global warming will probably always be up for debate but whether or not we should clean up our emissions should not be. I'm all for cleaning up our air. If we do it because of "global warming" then great, if we do for the health of our children then great. It's a win win situation.

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…
