Some Things Never Change

If you've read some of my posts in the past, you know that I prefer to avoid discussions on topics of religion or politics. There are plenty enough other blogs which cover these topics, that I don't see a need to join the fray of controversy. However, I must disclose that this post presents one person's observations of a society that is divided on political matters. An observation that was made about people in the United States by an author almost 80 years ago. With that disclosure out of the way, here's the story.

My wife and I enjoy visiting the Eastern Caribbean, and our travels have resulted in a genuine interest in the history of the islands and their inhabitants. That is what led me to recently gift my wife with a vintage book written by Desmond Holdridge. The story is a non-fiction, first-person account of Desmond and his wife, Elizabeth Hamlin Holdridge ("Bet"), who as newlyweds made their first home on the island of Saint John in the United States Virgin Islands ("USVI").

The book is titled Escape to the Tropics, copywrite 1937; published by Harcourt, Brace and Company (New York) and printed by the Quinn & Boden Company (New Jersey). For the first seven chapters, Holdridge does a splendid job of explaining how he and Bet interacted with the people of the USVI. It's a very entertaining account of island life in the early 1930s. Then the story takes an odd twist as Holdridge travels to British Guiana in search of Paul Redfern, a pioneer aviator who is believed to have crashed his plane in the South American jungle while attempting a long-distance flight from the United States to Brazil in 1927. Overall, it's a good vintage read, but this is not intended to be a book review, so let me get to the point of my blog post.

In the first chapter, Holdridge explains why he and Bet decided to "escape to the tropics." The Depression had drastically changed their lives in the United States, and they were looking for a new start. Holdridge writes of his friends' opinions regarding the administration, the Federal Government, and politics in-general. I found his observations to be rather profound, especially when considering the current state of our society's growing political division. It made me realize that some things never change.

It's best to let Holdridge's own words demonstrate my fascination with his perspective. The following text is taken from select paragraphs of the first chapter, beginning on page 10 of the book.

"All about us and all around the earth, near the forty-fifth parallel of latitude, the two most obvious ways of managing the vast, stupid, pathetic masses of mankind were feinting for advantage as antagonism deepened to a death struggle whose outcome will be peonage for most of us, no matter who wins. Karl Marx against Frederick William I; Stalin against Hitler; the State against the Man; the machine against the hand; the mind against the soul; our rich friends hysterically looking under the bed for Roosevelt and our poor ones ready to exchange their freedom for a cheap automobile and a comfortable place to defecate.

We both thought that these places where myriads of people lived together in a life not seen before -- stigmatizing as Fascists all those who said some of the things were good, and damning for Communists all those who said some of the old things were bad -- were perilous places, because an ugly and unnecessary sacrifice to human stupidity was impending."

"It was a rather trying period. Many times I sat down at my typewriter and, instead of getting on with the business of producing something, anything, on it, I would worry about the dividing line that was appearing in all the things and people I knew. A very good friend with whom I was on terms of long standing intimacy was also quite wealthy and it seemed that every time I visited him he was in a bigger froth over what he called 'this damn Communistic trend.' One evening he lashed himself into a great fury and, holding an imaginary bridle in one hand and an imaginary blade of some sort in the other, he roared, 'Ride the bastards down, that's what! Ride among 'em, slashing right and left.'"

"Another equally good friend was poor and, together, we watched the progress of the Austrian civil war, a thoroughly dirty business, to my mind. But this friend was passionately in favor of the left wingers. 'I hope they kill every one of the bastards!' he said, referring to the yokels supporting the right wing.

Since then they have both become more so. The rich one helps run, as an amusement, a newspaper full of absurd propaganda about the sanctity of the Republican party; the other is a lesser priest of the New Deal. Neither one will love me for mentioning this matter, but had I listened seriously to the rich one, I should have been so revolted as to become a Communist, and listening to the poor one would have inevitably made me a Fascist. As it was, they made me want to get out of it, for both kinds of men will, sooner or later, be at each other's throats. Nor did I like the contours of the worlds they wished to construct, and I thought too well of both to take sides."

"I made an honest effort to understand their perspective worlds, which is more than most of the people who damn their viewpoints do."

Upon reading this part of the book, I found myself very closely aligned with the thoughts of the author. His observations of his friends almost 80 years ago, were very much like my observations of my own friends today. Yes, it is true. Some things never change.

Facebook: The Bane of Society or Just the Next Thing?

Earlier this week, a friend of mine with a young teenage daughter sent me a link to this article... "Facebook is Spreading Like the Plague". The premise of the author's message (and I paraphrase here) is that Facebook is evil and will be the ruin of mankind. You can read the article and make your own assessment of the author's message, but I believe that my succinct summary is pretty accurate.

My friend does not currently use Facebook, and this article made him hesitant about allowing his daughter to use the service. He was also concerned about how prevalent social media services were being used at his workplace. As you might suspect, I have a different point of view.

How many times do you think this article, or some version similar to it, has been written in the past? I’m guessing that the same argument has been made by concerned parents for:

SMS / Text Messaging
MP3s and portable music players (e.g. iPods)
GameBoy
DVDs
Internet Forums
Mobile Phones
Instant Messaging (IRC/IRQ)
AOL
Email
CDs
Handheld Video Games
CompuServe
Prodigy
Video Tapes
Philip's Cassette Tapes
BBSs
Usenet / Newsgroups
Citizens Band Radio
8 Track Tapes
Color Television
45 rpm Records
Black and White Television
Amateur “Ham” Radio
33 rpm records
Telephones
Radio
78 rpm records / Victrola
Newspapers
.
.
Books
.
.
The Wheel
.
.
Fire

Okay, maybe I’m am being a bit of a smart alec, but I think that you get my point. There is always some new technology, some device or service, that is going to sap the life and intelligence out of our children and ruin our society and culture as we know it. These arguments are also often made in regards to the use of these same types of technologies in the workplace.

I believe that whether you are referencing your children or employees, it all comes back to an appropriate level of supervision and a reasonable amount of control. Facebook only consumes every waking moment of some children’s and adult’s time because it is allowed to. If a parent or supervisor is concerned about how much time their child or employee spends online, they only need to establish some house rules regarding the hours that it is permissible. It is no different for Facebook than what it may have been for any of the other items in my list above.

As a proponent of new technology and a self-proclaimed early adopter, I probably lean towards giving my kids more leeway on these matters. Our family's rules are generally based upon the children’s performance at school and with the successful completion of their household chores. If they can maintain exceptional grades, get their chores done, and still get adequate sleep and exercise, we generally don’t care about their time on Facebook (or Xbox, or texting, or…).

My wife and I originally established Facebook accounts to monitor our own children. That was the deal; the kids could sign-up for Facebook as long as they friended us. There has been only a couple of instances where we suggested that they delete a comment or photo. It has actually been a good life lesson and social experience for them. Interestingly, once we were on Facebook, my wife and I both discovered many old friends, some who were monitoring their own children. It has been fun to reconnect and we have also found that the service is a very good way to communicate with extended family; much better than our previous attempts at mass emails, family websites, or periodic newsletters.

If employees in the workplace are spending too much time using these services, then it is quite possible that they don’t have enough work to do or they simply lack the self-discipline to control their own behavior. I would classify that as a supervision problem; not a problem with the technology.

It can be difficult determining if these technologies are beneficial or detrimental in the work place, especially when they are first introduced. It’s not too hard to argue that a little music from Pandora in the background may help some people be more productive. The use of Twitter / Yammer could help people share information and improve productivity. Time maintaining a LinkedIn profile may help business development efforts.

There are no hard and fast rules. With notebook computers and mobile email devices, many believe that employees work far more hours per day than what was expected in the past, so allowing someone to watch a couple of YouTube videos while they eat their lunch, or maintain their Farmville crops before starting their long commute home may actually help the company keep the employees happy and working hard(er).

The best part of social media for me is learning how to leverage it for use in my day-to-day work. I can provide examples of projects and business development opportunities that were only possible because of my connections on Facebook and LinkedIn. I believe that anyone who is not leveraging those sites today is really falling behind. And I mean “leveraging” by joining groups, making new contacts and engaging in discussions, not simply creating a profile and then never going back to the site again.

So is Facebook the bane of society? Nah! It's just the next thing. Just wait. It won't take long for parents to identify something else that is sapping the intelligence out of their children and they will all forget about how awful Facebook is.

Natural Gas Conversion Table / Energy Equivalents

It seems as though I am often searching for this information. Maybe if I post it here I will be able to find it more easily in the future. Hope that you find this information useful as well.

Natural Gas Conversion Table*

1 cubic foot ("CF")                      = 1,000 Btu
1 CCF   = 100 CF        = 1 Therm        = 100,000 Btu 
1 MCF   = 10 CCF        = 1 Dekatherm    = 1 MMBtu
1 MMCF  = 1 million CF  = 10,000 Dth     = 10,000 MMBtu
1 BCF   = 1 billion CF  = 1 million Dth  = 1 million MMBtu
1 TCF   = 1 trillion CF = 1,000 BCF

* Based upon an approximate natural gas heating value of 1,000 Btu per cubic foot.


Natural Gas Energy Equivalents

                     1 MMBtu           Pounds of CO2
Fuel                Equivalent           per MMBtu


Natural Gas           1 MCF                 115
Coal                 83 Pounds              227

Do It Yourself: Serpentine Belt Tensioner Tool

My daughter's Honda Element needed some routine maintenance; replacement of the serpentine belt that connects the engine's crankshaft to the power steering pump, water pump, alternator and air conditioning compressor. This is a relatively easy job for any shade tree mechanic who prides themselves on completing a Saturday afternoon do-it-yourself project.

If you are about to tackle this task on a Honda Element, you may want to review the great instructions at the Honda Element Owners Club Forum. This site includes the belt routing diagram and handy pointers on how to best get to the belt as there is not much room for you to work around the side of the engine where the serpentine belt is located.

I am a fairly competent DIY mechanic and have a reasonable collection of tools to get the typical maintenance or repair job done. What I don't own is a special tool to loosen the serpentine belt's tensioner pulley. The tensioner automatically applies pressure to the belt to keep it tight while the engine is operating. Some vehicles have a spring-loaded version, while others apply tension with a hydraulic device. All of them require a significant amount of leverage by the mechanic to loosen the tension enough to allow the old belt to be removed and the new belt to be installed.

The tensioner will typically have a standard hex-head fastener for use with the tensioner tool. This is not an actual fastener, so you will not be tightening or loosening a bolt. In the case of my Honda Element, it is a 14 mm, six-point head. There's sufficient room to apply an end-wrench to the fastener head, but the relatively short 14 mm end-wrench does not provide enough length to loosen the tensioner.

Mechanics use a tool made specifically for this purpose. You can find several different styles of tensioner tools available for purchase, like this model from MAC Tools.

Most DIY mechanics do not have a specialty tool like this, often times because they are considered relatively expensive (e.g. $30 - $50) for a job that might only be performed once or twice in a vehicle's lifetime. The cost was high enough to inspire me to seek alternatives and think creatively.

Some vehicles may have enough room so that you may simply use a socket with a short length of pipe slipped over the wrench to extend the lever enough to loosen the tensioner. In my case, the Element had limited space and required a tensioner tool that was off-set to reach around various components in the engine compartment.

It may have been possible to use two wrenches in a cheater configuration like that shown in the photo below.

Although this method may work, I hesitate to treat my tools in such a way. End wrenches are not made to be used in this configuration, and the risk of breaking them or possibly permanently ruining them is just not worth the trouble. The length of the lever is also not that much better than the single end wrench alone, making this ad-hoc tool less than ideal for loosening the tensioner. I knew that there had to be a better option.

Looking at the scrap metal under my workbench, I came upon the following idea. To create a long lever for the 14 mm end wrench that allowed it to be placed in the off-set configuration required by my Honda Element. The metal is nothing special, just some bar stock from an old garage door opener. You may have something similar lying around your shop as well.

This first photo shows the components before assembly. The hardware is standard thread 1/4 inch, by the length required. 

The short strap sandwiches the open-end of the wrench to the longer lever. Once assembled, the bolts should be snug, but there is no reason to over-tighten.








In this photo you can see how the off-set is achieved.













The final photo shows the assembled tool. It worked exactly as needed without risk of damaging the belt tensioner or my tools. The best part is that the total cost for me was $0.00.


The type of serpentine belt tensioner tool that you need for your vehicle may be slightly different, but I hope that these photos help to inspire your own creativity so that you may also avoid the expense of purchasing an expensive specialty tool that you may never need to use again. Good luck with all of your shade tree repairs!
