Are you aware that you are sitting in an exit row?

First memorable flight ....

The air in our plane was heavy. I was young, eight or nine I think. Even so, it was obvious to everyone, even the infants onboard that this was a stressful situation. We were on approach to an airport in FL, having descended from 30+ thousand feet to our current altitude (looking back on it we were probably at about 10-15k feet in the air).

Regardless, our plane had descended right into the heart of the type of storm cell that only Florida can produce. The clouds were black, the thunder was loud, and the lightning would have been blinding if the torrential rain weren’t blocking the view.

The pilot had asked everyone to strap in tight, which was silly because the extreme turbulence had long since caused everyone to double-check that placebo (we all knew that if gravity had its way, the belts weren’t going to do much for us).

The plane dropped suddenly with a loud BANG, then regained some altitude. We dipped our wings, and the engines revved and settled in unpredictable patterns.

Like I said, I was little. My mom was crying, the woman in the seat next to us was crying. It was scary. I think that’s when I first started to dislike airplanes.

A couple of years later ....

We flew again, my mother and I. Once again solar radiation heated the earth’s crust causing warm air to rapidly rise and replace the cooler air above it. Turbulence. Again.

This time I was a little older and my mom gripped my arm with a strength usually associated with heavy machinery. It wasn’t as bad this time, but still it was scary. My mom was in tears, but this time I held my ground and tried to reassure her. “Something is wrong”, she said. “That man over there is PRAYING!”.

I looked over and sure enough, he was praying. Then again he was a priest, which I pointed out to my mother. “It’s ok. He’s supposed to do that”.

Several years later ....

I entered the airport with EXTREME apprehension. The memories of past flights and frightening unplanned drops in altitude played in my head with Michael Bay-esque special effects.

In the intervening years since my last flight I had remembered prior trips like a fisherman retelling a story about his last catch. Each time I remembered it, the turbulence got worse, the engine started cutting out, and towards the end there was fire. I had convinced myself that, twice in a row, I had barely escaped a certain and gruesome death. Sufficed to say, I wasn’t in a hurry to try my luck again.

However, I had recently bought a boat and the only way to get it was to fly to South Carolina. One of my best friends and co-workers was traveling with me (to his detriment). Adding to the stress was the fact that we were flying out on Friday the 13th under a full moon. I am not normally superstitious, but when it comes to airplanes, you can’t be too careful.

The other thing I am not, is a drug addict. However, that night and on that flight I had more chemicals in me than a hot tub. My doctor had given me happy flying pills and I took them like they were Pez. I could apologize to my friend for years and it still wouldn’t be enough.

A couple of years later (my honeymoon)....

Like or not, there are evolutionary aspects to men and women. At some point, women like to feel beautiful. Likewise, men like to feel MANLY (Arrrgh!). Well, there are few things manlier than getting married and being the protector, and sometimes the provider.

There are few things less manly than grabbing your new bride by the arm and screaming to the remaining passengers in the plane, “That sound you are hearing is our plane and it’s 1.2 million moving parts! They are making that sound because they are losing a battle with physical forces that have been in play since before our planet was formed! Those ancient forces would like nothing more than to reclaim this aircraft by drawing into the breast of our planet at a high rate of speed!”

Tonight....

I am sitting on an airplane for the millionth time in the last 6 months. I do this really often these days. I have been desensitized to air travel (thankfully). I no longer feel that stress. However, that doesn’t mean that I now enjoy this. I just have the ability to fly without being concerned that my last moments will be spent in a freefall and that I am going to die sitting next to a huge dude in a toupee, sandals with socks, and a muumuu.

I have instead refocused my hatred of flying, to a hatred of airports. Somehow, when I am in a terminal, I seem to attract people who are dripping fluids and are flaking skin. Sometimes they also have objects in tow that confuse and frighten me. That isn’t luggage lady! It’s a dog kennel with shoes in it instead of a dog (yes, I saw that tonight).

The whole process is silly; the angry people and the jockeying for seats, despite the fact that the seats are assigned…

However, at least now I feel better about the whole flying part. I have confidence in the 1.2 million moving parts in the aircraft, because I know that about 1/3 of them are spares in case the primaries fail. I also know that the plane’s computers are not powered by Microsoft software. So, I no longer worry that we will slam into a mountain while the pilot tries to reboot the plane because it froze up.

In some ways, I aspire to be like the engineers that created this highly redundant aircraft. All things being equal, these systems are really quite advanced. A lot of forethought went into them and all the systems were engineered with a “plan for the worst, hope for the best” mentality. Presumably, no one failed to consider disaster recovery because it wasn’t in the budget.

Despite the redundancies, there are still plane crashes every once in a while.

I think there is a lesson there for all of us as we consider our own businesses. I also think the lesson applies to all aspects of our businesses, not just technology. In an airplane, lives are on the line. Even with the best engineering, and anticipation of problems, and built in redundancies…. bad things still happen once in a while. So, it’s critical to learn from them when they do, and then engineer the lessons into the next revision.

So, to all of you out there that might read this I say to you, DON’T BE FOOLED! I assure you that if you talk to your employees, you will find that lives are on the line in your businesses too. It may not be about whether hearts are beating, but it is about the day to day lives of the people who work for you.

You need to act like an engineer designing a plane. Plan ahead. Don’t fail to invest in the redundancies that can save your employees life styles, and work to ensure that when you do have a failure you are learning from the mistake.

Thanks for stopping by, and while you are here, feel free to look through our website. You never know, you might find something that will help your plane stay in the air !!

Cheers!

Some things can never be virtualized...

I wandered my way down a muddy road through the woods today. I walked in the Rhode Island rain with my dogs at my side.



After a 1/4 mile or so, the trees thinned and turned to evergreens. My dogs looked at me and wagged their tails. They took off into the clearing and ran between the rows of Christmas trees. They were as happy as I have ever seen them.



We picked a tree, my wife and I, and after a few quick passes with a bow saw it fell. The dogs jumped and ran and wagged and barked and panted and pawed and rolled on the ground.



The tree came home and the lights went up. It's glittering in my living room, and the dogs are asleep in front of the fireplace. I made a grand dinner, and enjoyed a fantastic red wine. There is a movie on, and my wife is knitting on the couch.



Other than the millions of bits of data that are whipping through the air via my wireless card as I write this, there has been very little technology in my life today.



Actually, the only piece of technology I have worked with today is a favorite of mine. It's an incredibly advanced unit that makes its appearance in my house only once a year. It is precision crafted by complex moulders and extrusion machines, and is brimming with circuitry and I/O interfaces. It is extremely green, using very little power, but does have redundant connections to the grid.



Here it is:





It's a Christmas ornament that my wife bought for us. It's a hen house full of plastic chickens that sing in Jingle Bells in chicken language when you push a button.

Life lessons learned at walmart...

I realize that it's been a long time since I posted.

I also realize that this post has nothing to do with technology.

None the less, I would like to ask that you take the time to read this anyway.

I feel that it's important for us all to pass along hard won knowledge so that we can learn from each other and ultimately evolve as a species. So, in the interest of evolution I am throwing myself on the altar of humility and passing along this little nugget....

...Here it is...


LIFE LESSON #131
-----------------------

If you are ever in a Walmart on Haloween weekend,
And you see someone wearing a nun's costume,
Don't walk up and say, "That is an awesome costume!"

They might actually be a nun. :(


.................. Lesson learned.

Enough about the economy already!!!

I opened up CNN today and almost every story was about the economy. I was standing on a dock on the coast of MA and the launch driver was talking about the economy. I had a great dinner tonight, and everyone at the table next to us was talking about the economy.

I have had it with this topic.

I am also really tired of people that ask if I think it’s going to get better.

I sailed back to RI today. The weather Sucked (with a capital S). The waves on the ocean were supposed to be 2-4 feet, but they were worse than expected. On top of it, every half hour or so, a set of 6 – 8 foot waves would come through and throw the boat around. I was seasick, and wanting nothing more than to get through it…. just like most of us are with the economy right now.

The thing I always have to remember in weather like that is that if there is any one constant, it’s that there IS NO constant when it comes to the weather. It WILL change. Guaranteed.

It may get worse, but in the end, it is absolutely going to get better.

Sure enough, when we made the turn into the Sakonnett river the waves died down, the wind was across our beam, and we had a brilliant sail to the mooring.

So if you are seasick and just trying to get through the economic storm, remember that every once in a while you are going to get that set of really large waves that scares the crap out of you. That’s the cycle. It’s nothing to be afraid of. At some point, we will all make the turn into the bay and things will start to get better. Things change. They have to. It’s what things do. Especially the economy.

And when things do get better, I am SO gonna buy a soft ice cream machine for the office :)

What is "green"?

Are hybrid cars green? Maybe... until we have to dispose of all the highly toxic batteries they contain.

Are fuel cell cars green? Perhaps... unless you wonder where are the hydrogen they use comes from (strip mining coal in case you are curious).

Are offshore windfarms green? Could be... as long as you don't mind the total disruption of marine eco-systems and ocean currents.

Is solar power green? Certainly... of course those darn batteries we have to store the power in are an issue again.

So. What is Green?

Here is a list of Green things I have encountered on my vacation so far:

  • Seaweed that I pulled out of my shorts after swimming.
  • Seaweed that I found in the cockpit of the boat after the dog went swimming.
  • Seaweed that I found in my bunk (presumably put there by my dog)
  • Seaweed in the sailcover (put there by a seagull I think)
  • Seaweed on the sushi I had for lunch on Tuesday (I love irony)

This has been the summer of seaweed for me. Is there a way to turn this into renewable energy? No. What does this have to do with the beginning of this post? Nothing. Why did I rant about renewable energy? I needed a segway to talk about seaweed.... get off my back already.

But seriously, we do need to work on some of those renewable energy issues....

“Best Practice” doesn’t make perfect

I spend a lot more time than you would think, questioning technology. Yes, I am an IT professional...but I don’t necessarily believe in technology for the sake of technology. In fact, even when I do think a technology is important, I question the way that it should be deployed.

Some of the best, and ultimately the most productive, conversations and/or arguments that Envision’s engineers have are about how and when to deploy technology. I take my role as CTO at Envision very seriously, and find myself playing devil's advocate and often forcing my peers to reconsider what they think they know to be "best practice".

I have often felt that one of Envision’s biggest strengths is that we don’t take "recommended deployment guidelines" for granted. In the end, these are always written to serve the vendor’s best interest, and they rarely take into account the interaction between disparate technologies. So, when one technology’s "best practice" runs contrary to another technology’s "best practice" what do you do? Did you even see that coming in the first place?

If you work at Envision, you probably did because we spend a lot of time looking ahead and planning for the future. However, not every tech company is like that. In fact, we have worked on numerous systems whose primary problem was that a prior vendor just drank the coolaid of some manufacturer without thinking much about it.

What has me thinking about this? Mostly it’s that my boat just got a little more "techie".

I generally resist the addition of technology to my boat. Oddly, I am saying that as I sail south with a computer on my lap and a connection to the internet :)

Nonetheless, I don’t have an electronic chart plotter, or GPS integrated electronic navigation software, or even a color GPS display. This boat has always been my oasis from the technological. I still use paper charts, a compass, and a divider to plot my courses; and I have never pushed a button that would raise a sail. However, as I said, my boat did get more techie this season. I have installed a hydraulic autopilot, and I have named it Otto.

That is right...this boat can now drive itself.

I wasn’t sure I was going to like this, but I can now say (without hesitation) that this is the single coolest, most rock’n-ist, ultra-mega-awesomest, bomb-diggity thing I have ever installed on the boat. I just totally love riding along without having to man the wheel every two minutes. I want one of these in my car. In fact when I am old and / or lazy (er), I may even install one on my powerchair.

This is an example of the right technology at the right time.

Long live Otto!!
