The explosion in the sale and use of smart phones has spawned a new cottage industry among computer programmers. The slogan, “There’s an App for that!” has never been more true. Whether you use a Blackberry, an iPhone, or a Palm Pre, the list of programs (or apps) that will run on your new phone grows daily.
There are apps that allow you to surf the web, check the weather and book reservations at a local eatery. You can use you iPhone as a carpenter’s level, a geographer’s compass, musical instruments of all stripes and even a video camera.
Most of these applications are free or cost less than two bucks each and can be downloaded to your smart phone using the 3G network. The cost of the purchased apps is added to your phone bill, or in the case of iPhone apps, charged to your iTunes account.
While the proliferation of these apps is welcome news to the folks at Apple and the other smart phone manufacturers, there is one concern being raised by almost all of the major players in this smart phone game.
On Wednesday of this week, Apple executives are inviting application software developers to a special meeting at the sprawling Apple Corporate Headquarters in Cupertino, CA. The meeting is open to all smart phone application developers, not just those writing software for the iPhone. Executives from Apple will be sharing the results of some new market research that shows that the interest in new apps and in new phones is beginning to dwindle and if that trend continues the brisk sales of smart phones may dwindle as well.
Steve Jobs, Apple’s CEO, will report that the increased number and complexity of the apps installed on the average smart phone are having serious negative unintended consequences. The phones are getting heavier and heavier with the installation of each new app. Jobs will urge programmers to use more efficient coding in order to keep of the files lighter.
In a recent press release, Jobs points out that a fully loaded iPhone with 100 Apps can weigh eight ounces, or a half a pound, more than the same iPhone weighs in without
the apps. “The software developers need to be more attentive to how many bits and bytes are really required for each app,” said Jobs. “If we don’t do something to address these overweight apps, before long the iPhone will feel like a brick in your pocket.”
You can read the summary of the discussions on the Apple.com web page. It will be released on Thursday, April 1st.

More on "Gs" and Smart Phones
This is the second installment of our discussion about cellular data networks and smart phones. Last week we discussed the development of the high speed wireless data networks expanding the applications available on today’s smart phones. The smart phone is not only a mobile telephone but can handle many of the tasks once requiring a computer.
Smart phones began to hit the market in the late 1990s and were essentially a mobile phone with a few applications like a personal calendar and address book built in. The explosion in popularity came with the release of the Blackberry in 2002. The Blackberry was one of the first devices that were designed to take advantage of the new high speed mobile networks. That particular device was so popular, for many the name “Blackberry” has become the moniker used for any brand of smart phone. In less than 6 years the user base for Blackberries has topped 32 million. In 2007 Apple released the first iPhone and like so many Apple products, its design (both physical and technical) and applications changed the industry.
Smart phones now can do a host of tasks from the ridiculous (there is an app that turns your iPhone into a harmonica) to mind blowing (Shazam, a smart phone app can recognize music being played on the radio informing the user of the name of the song, the artist performing the song and how one can purchase a copy of the song.) There are apps that turn your smart phone into a GPS. Others will find a good restaurant close by and even make reservations.
Most now have very good digital cameras built in as well as video recorders. You can capture Billy’s dance recital on video and email it to Aunt Esmerelda. Or you can download the pictures or video to your computer and edit a masterpiece to upload to YouTube for the whole world to see. In some countries, smart phones are replacing the credit or debit card. Waving your phone in front of a soft drink machine replaces the need for cash.
With more and more of us using these devices, the 3G networks are getting overloaded. There are already instances in some of the larger metropolitan areas of the country when the networks are so overloaded that none of the subscribers can get service. While these outages last only a short time, for those truly addicted to their smart phones, a few seconds being off the net seems like an eternity.

Are Three "Gs" Better then Two "Gs"?
The battle continues between AT&T and Verizon. “My 3G network is better than your 3G network!” Maps fill the pages of TV Screens, newspapers and magazines comparing the networks’ coverage. Both promise a more robust and universal network. A week or so ago I was invited to speak before the Harrison Historical Society about new technology. Among the very insightful questions was one about this very issue. The question began with a request to define the term “smart phone.” To answer that question we need to define what all these “Gs” really mean.
Back in the dark ages of mobile phones when the smallest of the available devices was briefcase-size and had a battery that weighed a pound, all mobile or “cell” phones used a network dubbed “1G.” The “G” stands for generation and this network technology was the first generation. It was developed in the early 1980s and was fine for the analog devices in service at that time. It did require phones with protruding antennas and many cars required a little black antenna to be affixed to the rear window. In fact, in the early days that antenna was a sort of status symbol indicating that the driver had a cool new cell phone. You could even buy fake antennas to fool your neighbors that you were part of the cell generation.
The 1G networks were soon replaced by 2G, the first of the digital networks. With the number of mobile phone users exploding in the USA and around the world, the old analog system just could not handle the traffic. 2G systems could accommodate 50 or more simultaneous conversations on the same frequency and allowed for smaller phones with built in antennas. It was not, however, capable of efficiently handling data.
As more and more people wanted to be able to be connected while on the go, not only with voice but with email, the web, navigation services, and now even social networking, the carriers like Verizon and AT&T needed a revolutionary upgrade and that resulted in the current 3G, and soon to be prevalent, 4G networks.
The smart phone requires these networks as it essentially is not only a mobile telephone but can handle many of the tasks once requiring a computer. Next week we will look at smart phones in more depth and answer the question about who has the better G.

Movies From NETFLIX Online
In 1997 when the fledgling company NETFLIX began shipping movies on DVDs to subscribers nationwide, few would have predicted how fast the service would grow into an icon of electronic entertainment. The success of the company, which was then based on a very old business model of a physical library and 250 year old distribution system, the US Postal Service, was extraordinary. For those unfamiliar with NETFLIX, subscribers set up on line a list of movies they would like to see and, depending on the type of subscription, a selection of movies on DVDs is sent to the subscriber’s home each month. When you return one, another from your list is automatically sent. The DVDs are mailed back and forth. This system has been in place now for more than 10 years but its is about to change.
Just like the sale and distribution processes of music quickly changed from a physical product and physical distribution system, the distribution of movies is quickly following suit. Remember when CDs were once purchased in “Record” stores? Now we have a system that distributes music as MP3 files bought from on line stores like iTunes or Amazon.com.
NETFLIX now offers a complete online service that sends movies to your home using the internet. No DVDs, no trudging to the post office, no loosing the DVDs under the couch. Just like the original service, subscribers set up a list of movies they would like to see and one by one the selections are sent.
There are various ways of receiving these online movies but the one common denominator is a high speed Internet connection like Road Runner or ZoomTown. There are many devices available that can receive, store and play out the movies. For example, many of the new gaming devices such as the Xbox 360 or the PlayStation 3 can be used. There are several DVD players that are NETFLIX compatible. Sony and LG have HDTV sets that can receive, store and play out the movies directly from the Internet. You can also use a desktop or laptop computer.
The cost of the service runs from about $10 per month to $20. The number of movies you wish to receive dictates the price.
While the online delivery of movies is still only a small part of the NETFLIX business right now, if it develops as quickly as iTunes and Amazon MP3, it wont be long before the DVD may be as scarce at an LP.

See What You've Been Missing
With all the hype and advertising promoting cable TV and satellite services, it is interesting to me that many people still don’t realize that there are many channels available free over-the- air. In fact, since the digital conversion, the number of channels that most of us can get using an antenna and a digital TV or a digital converter box on our analog TV has gone from about 6 to 17 or more.
We are indeed creatures of habit and as such we tune in good old Channel 9 or 19 and may not think about the fact that these and most other channels have multiple offerings. For example, Fox 19 has two services. Channel 19.1 carries the traditional local news and the Fox network which they have carried for years. On Channel 19.2 there is a completely different service called THISTV. This second channel broadcasts mostly movies and some children’s programming.
On CET Channel 48 (full disclosure here, I work for CET) there are three discrete services. Channel 48.1 carries the traditional schedule of PBS programming. 48.2, with the moniker “CET Create,” has a 24/7 line up of “how-to-do-it” programs. Beginning February 1st, Channel 48.3 began “CET Arts,” a full schedule of programming spanning the visual and performing arts.
All of these channels can be received using a digital TV set and antenna. If you receive the primary channel, i.e., 5.1 or 9.1 etc., you can also get the additional channels. On most TVs and digital converter boxes, all you need to do is press the “Channel UP” button on the remote and you will see the additional channels.
Some of these channels are available also on cable but none of the additional channels are available on either the Dish or DirectTv satellite services. For example, the “CET Arts” service is available on the Time Warner Cable digital tier on Channel 987.
Even if you use a cable or satellite service, you can still set up your TV to receive over- the-air channels as well. For older sets it may require some cables and switches; for most new TV’s it only requires an antenna connected to the new TV and selecting the right input. If you want directions on how to do it just send me an email (jdominic@cetconnect.org) and I will send you the information. Be sure to tell me the type of TV you have and if you have a cable or satellite service.
Look around the over-the-air landscape, you may be surprised to see what you have been missing.

Pandora, Music Lover's Dream Come True
Few aspects of modern life have been more affected by the digital revolution than the music industry. The way music is performed, recorded, edited and distributed, paid for and listened to all have been revolutionized. Personal collections of recorded music, once filling shelves in the family room, are now carried around in your pocket. Browsing through a “record store” looking for some hard to find treasure is now done on line and rather than waiting for the “record” or “CD” to be delivered, it is available instantly as a down load.
I recently was introduced to an online service that will be of special interest to those who like to explore various genres of music as well as those who have very specific musical tastes. The service is called Pandora.com, and just like its namesake this Pandora’s Box is brimming with surprises. Unlike the mythic box, the surprises are delightful.
When you sign on to Pandora using your computer or smart phone, you are asked to “create a new station.” This can be based on a genre of music like classical, country, rock, etc. or more specifically based on a single performer like Michael Jackson, James Taylor or Frank Sinatra. You can also specify a single composer like John Williams, John Denver or Johann Sebastian Bach.
Once you enter the information, Pandora will create a “station” just for you and begin playing music based on your preferences. The search technology is similar to the one used by Amazon.com; “If you liked this book you might be interested in this other book.”
The really neat thing about Pandora is that the selections made by Pandora can result in music you would have never sampled but when you hear it you really like it. If you hear a song that you don’t like, you click on it, and Pandora stops playing it and uses that information to learn more about your tastes and make more informed selections in the future. You can set up several “stations” so you can listen based on your mood. While reading a book perhaps some classical sections are best. Cutting the lawn or jogging, U-2 fits the bill.
Pandora comes in different flavors. You can use it free for 40 hours a month with a few commercials per hour. For a subscription of $39.00 a year you can get an upgraded version with no commercials and better audio fidelity and no limit on the number of hours you use it. All versions give you lots of information about the music, the performer and composer. You can even order the music online as a MP-3 download or follow a link to purchase a CD.
Pandora can be used on your desktop or laptop computer as well on most mobile devices. If you use it on a mobile device make sure you have an unlimited data plan or you will have a surprise the when you get your next bill from your carrier.
If you like music, I recommend trying Pandora. I have it playing in the background often when I am writing. In fact right now I am listening to Loggins & Messina.

Battery Powered DTVs Now Available
A couple years ago when we were getting ready for the digital broadcasting conversion, I got several questions about battery operated digital TV’s. Many people were using battery powered analog TVs while on vacation or at their weekend retreats. These were places that did not have access to electric power. Others wanted the security of using a portable TV during power outages and severe weather. Since at that time the choice of battery powered digital TVs was very limited and those that were available were very expensive, I recommended waiting before buying. Things have changed, inexpensive digital TVs are readily available and the prices have fallen. But I am still recommending that you consider all the pros and cons before buying. There are significant differences between the old analog battery operated portable and the new DTV models.
For the last few weeks the Sunday newspaper advertising supplements have featured models with prices under $100. For example, hhgregg had one on sale for $99 that has a built in DVD player. This one, like most others, uses an LCD screen that measures about 9 inches diagonal. It can use the internal rechargeable batteries or an AC adapter for use when electric power is available. I use one in my kitchen. It allows me to prepare dinner or wash dishes and still keep up with the local news.
While these TVs do provide an acceptable picture there are two weaknesses that you should know before going out and buying one. The first deals with the antenna. All the pictures in the ads will show these small TVs with a single built in telescoping antenna. The problem is that in my tests, none of these antennas worked well. I tried various locations. Some test sites were as close as 2 miles from the TV transmitter. In order to get all the stations, I needed to disconnect the built in antenna and connect a standard UHF/VHF rabbit ears indoor antenna in order to get good reception. For example, I live on a hill near Harrison and can literally see the red lights on the tops of the various TV transmitting towers located in Cincinnati. In order for me to get all the Cincinnati stations, I need to use a UHF/VHF antenna mounted on top of the cabinets in my kitchen. Using the antenna built into the TV gets me almost nothing.
Unlike that analog portable that you may have carried with you to the park or camping that pulled in, albeit fuzzy, the major channels with the built in antenna, don’t expect that from the DTV. And for sure forget about using it in your car with the DC adapter. The chance of getting any reception of DTV signals in a moving car is next to zero.
The second issue is battery life. Most internal batteries will give you less than 2 hours of use without recharging. The circuitry in DTV tuners and the LCD screen take lots of power. It is unfortunate that most come only with internal non replaceable rechargeable batteries. Once they are drained, you are out of luck. Remember the wind storm a couple years ago? I sure would like the option of using standard batteries as well. That way you can have a supply on hand for extended power outages. So far I have found no set that offers standard battery operation.
These new sets can be handy but they will not give you ease of use and when in battery powered mode, you will not get the same extended playing time that you may have had with the old analog set. Still, they make a nice addition to the kitchen or workshop.
