A discussion of current information technology and future trends. The content is designed for a broad audience that wants to know what is happening but does not want to spend all their waking hours trying to keep up.
Have you heard the one about the guy using Apple maps
who walks into a bar, or maybe it was a church - or bowling alley? You've
probably know by now that Apple messed up when it replaced its previous
map app with a new version in September. In a nutshell, the previous
version was based on Google maps and Google and Apple are fierce
competitors so they had to do something. The Google version was crippled
on Apple devices and did not provide turn by turn directions like it
did on Androids. My only complaint is that everything in Bemidji is one
block west and fifty feet north of where Apple says it should be!
The biggest complaint is that there is no "street view" as in Google. I can live without that considering how great the turn by turn directions work. However the most important hidden new feature
is the significantly improved graphics engine. This new design uses
vector graphics to drastically reduce the amount of data received which
can be a boon on a limited dataplan. It also means you can navigate in
areas with no phone service. That part is pretty amazing when you see it
in action. As you zoom in and out - even in a remote area with no cell
coverage - you'll see high resolution images at any magnification - no
more reloading images. Google is reportedly putting the finishing
touches on its own map app for Apple. More on that later.
Most
people I know don't want to be techies and I don't blame them. But
there really are a few things you should know to keep you out of trouble
and one of the most important and easiest to do is to understand web
addresses. A large number of scams involve tricking you into visiting a
malicious web site and many of them are very easy to spot. Email and web
addresses up to the .com/ part is what matters.
There was a time when fraudulent messages were so phony they were easy to spot - not any more. I'm going to show you three real messages I received and how I determined they were all fakes. In every case, I looked at the two or three characters preceding the first slash; this is called the top level domain. The IRS for example would likely have a TLD of .gov. It may be exciting to say a message from Christmas Island but it is unlikely the IRS would have a site registered there - .CX.

Don't you hate it when people make up new words to obscure stupidity?
"Company XYZ is doing really well - now they just have to figure out a way to monetize their business model"
- we used to say "make money". Can you imagine what people would have
said thirty years ago if a major auto company said, business was great,
people like our cars now all we have to do is figure out how to make a
profit!
The sure way to make money gambling is to own a Casino. The way to make money on an over-hyped tech IPO like Facebook
is to be an insider who arranges the "deal", lines up the suckers and
takes the money before the bank opens. Of course this headline days
before Facebook went public didn't help:
In
case you don't know it, Facebook and Google are both built around the
concept of selling ads to people who think it is worth it. To revise a
very old saying - "If it's not good for General Motors, then (maybe)
it's not good for the country." Certainly it's not good for the
investors who have been losing ten percent per week since they bought
Facebook stock.
Right
off the bat I'd like to say if you don't plan to use a smartphone as a
smartphone - which usually means downloading apps - then don't buy a
smartphone - buy a dumb phone. There's no shame in that - it doesn't
mean you are dumb. Now, for those of you who do want a smartphone, it's
time to listen up. I frequently get questions from people with an "xyz"
smartphone about how to use specific features. Unfortunately most of the
time I have to say I don't know - not a fun prospect for a life long
geek. I have to explain there are hundreds of smartphones and I don't
even try to learn about them all.
In the good ol' days when PCs were a hot topic, there really was only one basic PC and nobody had to make hard decisions. How can that be? Simple. The hardware consisted of the latest Intel
processor, the largest hard drive available (made by a company no user
could identify) and the only thing different about them was color and
price. At the office, you probably didn't even get a choice of color and
it wasn't your money anyway. The software consisted of the current
version of Windows and a copy of MS Office.
The
upside of this uniformity was that you knew many people with the same
computer as you - maybe with a different company logo on the outside but
the same computer no less. Have a problem with Windows XP, your friends, co-workers and everyone at every electronics store was familiar with it. Not so today. If you have a problem with your "xyz" smartphone, there's only a very small chance a friend will have one like it. Now repeat after me "not all Android phones are the same". As I've mentioned in the past, people are buying on features and price and not on the OS. There are currently dozens of variations of the Android OS out there. The latest one - Ice Cream Sandwich - is only installed on a small percentage of devices and we're now hearing about "Jelly Bean". To
amaze your friends tell them Android operating system names are derived
from treats in alphabetical order - originally called deserts - but you
have to stretch it when you run into some letters - Ketchup for desert anyone?
The
rapid roll out of Android versions and the fact that carriers freely
modify them is causing havoc for the developers. When I do get the
questions about a phone, I always ask "how did you pick that one?" The
responses are incredible - "I liked the feel of it in my hand", "the
salesman said this was the best one for me", "I didn't want an iPhone
since I use PCs" - huh? The most important missing question when a smartphone decision is made is "who am I gonna' call when I have questions?"
Unless you know the answer to that question you should never commit to
spending two thousand dollars for a two year contract on any phone.
In the category of "how times have changed' when you see someone with a shiny new laptop, you don't often ask about megahertz or megabytes (you never really understood those anyway). No, you ask those all important questions:
This long promised glossary is not alphabetical since that doesn't work very well for this type of material. It is loosely organized in some logical groupings but it is short enough that the best approach is just to skim the words in the left column to find ones you've heard and wondered about. Often it seems like you are the only one in the room that doesn't know what the "cloud" is but you are not alone. Here's your chance to catch up and get ahead of most of the people you encounter.
Word
Definition
Mobile Devices
Smartphones and Tablets are the most
talked about mobile devices today. In a word, they are computers that are
portable in the extreme. They have processors, memory, operating systems,
keyboards and touchscreens for data entry and for displaying the output. Most
importantly, to qualify as general-purpose computers they allow user
installation of programs (apps in today’s vernacular). Without this last
requirement some current refrigerators – and future toasters – would likely
qualify as general-purpose computers.
Tablet
Tablets
are at the large end in terms of mobile screen size – typically seven to ten
inch diagonal measurement. The other primary difference from smartphones is
that tablets generally don’t have a connection to a cell phone network and if
they do it’s not used for phone calls – just for Internet activities. There
is nothing stopping a company from putting a cell phone capability into a
tablet. Two reasons they probably won’t: the tablet war is turning into a
price war and every penny they can cut from the cost is a penny they can
keep; the idea of talking into a tablet just seems strange and most tablet
owners have or will have a cell phone. Nomenclature will be confusing for a
while since someone could – and probably will – put telephone circuitry into
a ten inch tablet or remove it from a four inch smartphone.
Phone - Smartphone
Smartphones allow users to install apps of their choosing
Phone – Feature phone
Feature phones can perform tasks using the Internet such as email and web surfing.
They come with a fixed set of apps – calendar, contact list, etc.
Phone – Cell phone
Simple cell phones are used only for making
phone calls.
Cell phone contracts
Many phones receive
service from one of the carriers (AT&T, Verizon, etc.) based on a
contract. Monthly charges are based on four elements.
1)Number of
minutes of call time
2)Number of text
messages
3)Amount of
information sent and received (the dataplan)
4)Fees and taxes
Dataplans
are likely to cause significant confusion in the future since we are using
mobile devices more frequently and very few people know how many megabytes
are in a video.
Traditional cell phones do
not require dataplans. Prepaid cellphones are traditional cell phones that
allow you to buy minutes in advance. These are individuals with limited need
for a cell phone.
Internet TV
Much of our television in
the future will come through the Internet. A simple computer can be
incorporated into a TV set or offered as a standalone box. No matter the
form, these are real computers – generally with limited storage. Content is
streamed from the Internet not stored locally. They use the TV as a display
and a remote control or keyboard for input. Some have relatively simple
choices while others offer a full web browser on the TV.
App
An app is just a new name for a program. You used to install
programs; now you install apps.
Operating System - OS
All computers including
desktops, laptops, smartphones and tablets have a program called the operating system (OS). In the past
the three best-known computer operating systems were Windows, Mac and Linux.
Currently the top mobile operating systems are Google’s Android and Apple’s
iOS. There are at least ten mobile operating systems today but few are likely
to survive very long.
UI – User Interface
Ever since Apple
introduced the graphical user
interface in 1984 (icons manipulated with a mouse on a “desktop”) the User Interface (UI) has been
critical. Methods of interacting with a computer (using a mouse and keyboard)
have progressed slowly in recent years but touchscreen technology is changing the UI at lightening speed.
Wireless connections WiFi, Bluetooth, etc.
All of these are just the
various types of radio signals that are used to connect devices wirelessly.
They’re called radio signals since they were used for radios decades before
computers were invented. For a more detailed explanation check out my July blog post.
Cloud
In the simplest terms the Cloud means storing information
and running problems on the Internet rather than your PC. For the
professionals it is much more complicated and you can read more in my June
2011 Newsletter.
Internet and the World Wide Web (Web)
The Internet consists of millions of computers connected together.
They may be gigantic machines but even your personal computer is an Internet
computer when it is online.
The World Wide Web consists of software and files that allow anyone
to use Internet computers to store and retrieve information - information
that might be text, photos, music, etc.
A web server is one of the most important web programs since it
sends files (web pages) to you when you click on a link or type an address
into your browser. It sends (or serves) the page to you and then waits
patiently in case you want another file – possibly serving thousands of files
to other users in the meantime.
Sending and retrieving web
files is only one use of the Internet. Email is another. Email uses the
Internet but not necessarily the web. This situation is somewhat confusing
since many email services are now available through your web browser.
Protocol
If two computers (or two
people) are going to work well together, they have to agree on how they will
do things. Often these agreements are called protocols. Who sits where at a state dinner is
determined by the protocol for state dinners. In the case of computers, how
they exchange information is called a protocol that is described first on
paper – which signals are going on which wires, etc. To be able to
communicate both computers must have a program that implements a particular
protocol. Basically it’s a description of what characters will travel between
the two computers and in what order. You may hear about IP addresses – these
are the addresses used by all computers on the Internet (even yours)
according to the Internet Protocol.
Encryption
We all remember making up
secret codes at a very young age. Encryption
is just the name for a myriad of techniques that can transform a message –
text, photo, etc. – so it cannot be understood if it falls into the wrong
hands. Breaking enemy codes was a major undertaking in World War II and today
any spy agency worth its salt is doing the same thing with information
intercepted on the Internet.
Units – Bit, Byte and Megabyte
We’ve heard that all
information in a computer is stored as zeros and ones. If you put enough
zeros and ones together you can represent a text book or reproduction of the
Mona Lisa. If you take an image from your digital camera or off the Internet
and enlarge it many, many times, you will see individual picture elements,
(pixels or dots). Each pixel is a single color and that color is represented
by a number – a string of zeros and ones.
Storage space for a single
zero or one is called a bit – just
like storage space for a number from 0-9 is referred to as a digit.
A group of eight zeros and
ones is referred to as a byte. As
a rough approximation a single character of text can be represented by a
combination of zeros and ones stored in one byte (a=00000001, b=00000010,
etc.)
A kilobyte is roughly one thousand bytes; a megabyte is roughly one
million bytes and a gigabyte is
roughly one billion bytes. I say roughly because there are two definitions
for each of those terms but they are similar enough for most people to
ignore.
Pixel
A pixel is a single point (dot) in an image. A ten megapixel camera
can take pictures with approximately ten million pixels. Each pixel requires
several bytes of memory to record the color – see pixel depth.
Pixel depth
Each pixel (dot in an
image) can represent millions of different colors. The value stored for each
pixel indicates the color of that dot. The higher the pixel depth (more bits
to store the value), the more colors that a pixel can represent. For example,
if you stored the color of a pixel as a two digit number, you could store up
to 100 different colors – 00-99. Computers store values in binary but the
principal is the same.
Compression (JPEG or JPG for still pictures and
MPEG for videos) In practice there are many other compression standards.
Storing a color value for
every pixel in an image results in very large files. It is common practice to
compress the image by, for example, indicating that a large area of sky is
blue with only a few values – the numeric value for blue color and the
boundaries of the block of sky. A tiny speck of a bird in the sky might just
be tossed out in the process. The higher the compression, the smaller the
resulting file and the more image points will be lost or modified.
Videos can have each
individual frame compressed in this way but add interframe compression; if
two successive frames are nearly identical, only the changed pixels are
included for the second frame.
Broadband
Generally used to describe
high speed Internet access with a variety of speeds. Usually contrasted with
dialup connections.
Modem/Router
The telephone system was
originally intended to transmit human voices. When we began sending
information between computers over phone lines, there had to be a way of
changing zeros and ones to sound patterns (called modulating) when they were
sent and then back into zeros and ones (demodulating) at the other end. The
device we use is a modulator/demodulator (modem) - one at each end of the line.
If there are multiple
computers in your home or office and only one Internet connection, you need a
way to keep transmissions separated. Signals from a computer connected a
wireless network go first to the router which attaches a numeric code to
indicate which computer sent it. When a response to that transmission is
received over the Internet it comes back through the modem and then to the
router to send it to the correct computer. Today modems and routers are
usually combined into a single device that does both jobs.
HTML
A file type indicates what type of program created or can read a
particular file - .doc for MS Word, .xls for Excel, etc. Files that come over
the Internet to be displayed by a browser like Internet Explorer, Firefox or
Safari use .html or .htm as a file type.
Flash
Flash is
a type of file often used for video but for other purposes as well. Flash is
losing favor as other more modern programming tools are developed, e.g. HTML
v5.
PDF files
The pdf file type was developed in response to the many incompatible
file types that were causing confusion. The idea was that all computers could
have a pdf file “reader” so any document – word processing, spreadsheet, etc.
– that could be converted to a pdf format could be read on any computer.
URL
A Uniform Resource Locator is the fancy name for the Internet
addressing scheme. You could type an address into your web browser and call
it either an address or URL. URL is the cooler term.
Touchscreen
Smartphones and tablet
computers use display screens that can detect the touch of a finger or
special soft stylus. They can be programmed to respond to various gestures –
tap and double tap, as well as sliding motions involving several fingers.
Cheaper touchscreens require pressure but later, higher quality screens
respond to a very light touch. Touch gestures often imitate mouse clicks –
double click/double tap, click and drag/tap and drag, etc.
Domain Names
To provide some structure
to Internet addressing, the scheme starts with Top Level Domains. These
include .com, .edu, .mil, .gov and .biz - called generic TLDs. They are not
associated with any country. TLDs also include two letter country codes .us,
. ca. ru, etc. New top level domains are just being rolled out now.
Any organization that
wants an Internet address can apply for its own name – braley.com or
braley.us – consisting of a specific name associated with one of the TLDs.
Needless to say most common words and proper names are already taken.
This is how requests for
information are routed around the Internet. Braley.com is essentially a
folder of files stored somewhere on the Internet. One of those files is the home page that will be retrieved if
no further information is provided. In most cases, someone might want a
specific file and request braley.com/clients.htm. This is a file in the
braley.com folder
www, http, https, ftp
A web file usually starts
with www (world wide web) but if
you leave that out, your browser will generally insert it for you. The
Internet operates on Hypertext Transport Protocol - http -but again the browser will often add that to an address.
Secure web sites use https and it
is important to put that in to access those sites. FTP is the file transfer protocol – not a web service – which at
one time required a separate – non-browser – program. But like many other
services, FTP can usually be handled by your web browser.
Browser
A web browser was once a program with one purpose – to display
files ending in htm or html. These programs have been greatly expanded to
perform numerous other functions – see FTP above.
Email and web capitalization
Email addresses are NOT
case sensitive. Web addresses are NOT case sensitive up to the first slash
following the .com, .gov, .us, etc. Following that slash they may or may not
be case sensitive so you need to assume they are unless you know otherwise.
Braley.com is never case sensitive but the “file1.htm” in
Braley.com/file1.htm is likely case sensitive.
This seems like such an obvious question I'm amazed I've not seen it addressed more often. Android promoters gloat that their "platform" leads in sales but never explain why their tablets don't do the same. I have a theory. When most people buy a smartphone, they are thinking about its capabilities as a "phone". How many minutes do I get? Which carrier do I prefer? Is there a family plan? etc. The "smart"phone, i.e. computer aspect, is secondary. They may never address the operating system or the app stores since they are thinking in terms of replacing an old phone. Starting with that premise, anyone searching for a phone would more likely end up with Android - they are everywhere and many are less expensive than iPhones.
Buying a tablet is a different proposition. Consumers have no tablet experience so they have no natural starting point. This forces them down one of two paths. A few realize they are really buying a computer and investigate all the relevant technology and many are likely to go with Android. Most people though just buy what is available in most stores (iPad) or what their cool friends have (iPad). One of Apple's stealth moves with the first iPad was to place it in major retail outlets last year - Best Buy, Target, WalMart and Radio Shack - in addition to it's own 300+ stores worldwide. This leaves precious little prime shelf space for competing tablets.
If many smartphone purchasers aren't doing much critical thinking as I've suggested - after all they're just buying a phone - the companies may be forced to sell primarily based on price - as in the PC arena. While they may sell a lot of excellent Android handsets, they may not make sufficient profit to survive in spite of the sales figures. And speaking of sales figures, remember the difference between "shipped" and "sold". Sold is what matters; shipped means sent to retailers where they might languish for months before being sold - or returned to the maker.
If
there's one issue that haunts the Android "industry" it's the widely
discussed problem of fragmentation. Dozens of companies (Motorola, HTC,
etc.) make hundreds of Android models to be sold by numerous carriers,
in retail stores and online. There are differences in the phones -
different size screens, virtual or physical keyboards, price, etc.
Having choices is certainly appealing - with the iPhone it's black or
white, literally. However Android choices can be very confusing for
someone trying to find the "right" phone - like the potato chip aisle at
the quickstop - way too many choices.
Imagine if your one year old PC did not qualify
for the latest version of Windows.
This seems in some ways like the battle between Apple and Microsoft
for PC dominance but there is a significant difference. If
fragmentation in the PC world had been harmful, Apple would have been
the logical beneficiary because there were hundreds of PC manufacturers
over the years. But PCs were not all that different - they used the same
processors, the same disk drives, the same keyboards, etc. so
differences were either minor cosmetic factors or price. Most importantly they all ran the same operating system and most could be reliably upgraded for at least five years.
I've been excited about photo editing with a touch screen ever since I got my iPhone. The iPad and its numerous apps makes creating great images a snap. This does not replace "sturdy" desktop applications for sophisticated photo manipulation - at least for now. In particular ten inch screens will always be a limiting factor.
Having said that I wanted to show an example of what I did in a matter of minutes starting with a 3MP image taken with my iPhone while strolling along the Mississippi in Minneapolis. I sent the image to my iPad using PhotoSync and used four of the 187 filters in PhotoStudio to create the special effects.
At two recent lectures on Mobile Technology I surveyed participants on their use of social media. It was a simple eight question survey not directly related to the topic I was covering. Several points concerning the participants:
They covered a wide age range with many in the 30-50 year range.
They were above average in tech knowledge based on their professions.
Some were small business owners and others worked for companies of all sizes in the computer training field.
Three of the four questions ask about their use of Facebook and Twitter. The last question ask whether they owned a smartphone or tablet computer.
General results:
Nearly 80% had smartphones but only 17% had a tablet.
While two-thirds used Facebook weekly only one-quarter used Twitter that often.
Business application - use of Facebook and Twitter:
Facebook was used to communicate with clients by 40% of participants but only 20% used Twitter for that purpose.
In a similar vein 33% used Facebook to receive information from companies while 24% used Twitter to do that.
With a total of eight possible responses, a rough measure of "tech savvy" would be the number of boxes each person checked - have a smartphone, use Facebook weekly, etc. etc. Using that measure no one scored the maximum of eight while 26% checked three - typically Facebook weekly, have a smartphone and one additional item. 19% checked four or more but 7% did not check any of the eight boxes.
This was a small sample but I think the results are informative. First and foremost, even though everyone is told they have to use social medial to communicate with stakeholders, a significant majority don't do that at the present. As you might expect the few "heavy hitters" dominated the results and 38% had no business contact at all with others using social media. This is after several years of hearing how Facebook is taking over the world and "everyone" is doing it.
Like most surveys of this type, I made no attempt to assess how well these techniques worked - are people just tweeting and hoping it works or can they measure actual success in product sales or revenue results.
There are many other social media platforms I did not include - primarily to keep it simple. I assumed that a significant number where on LinkedIn but evaluating actual usage would have been somewhat more difficult. Several other lesser known services were considered and will be included in future studies.
How often do you hear someone talk about "what people want?" Whether it's politics or technology, pundits act as if all people want the same thing and they know what it is. This leads to ridiculous criticisms of things like the current smartphones and tablets; notice I'm avoiding the political part!
You hear, for example, "the iPad and other tablets are flawed because people don't like virtual keyboards - they want a real keyboard. The reporter goes on to say "when I write my stories, I blah, blah, blah." This storyline makes it sound like a) they know what everyone wants and b) they represent everyone by talking about their personal needs in the same sentence.
I'm pretty sure "people" don't all want the same thing - whether it's in their computers or condiments on their hot dogs. This is more than just a complaint about the state of journalism - it goes to the core of how computers have been developed over the years.
Real keyboard - you want a real keyboard!
Let's look at automobiles as a starting point. There are several dozen different basic auto designs because "people" don't all want the same thing. There are compact hybrids and nine passenger SUVs and a whole crop of "crossovers". Because PC functionality has been controlled by one company for nearly thirty years, only one version of one product was necessary - the Windows PC. I don't know what "all people" want but I do know that
The Perfect Tablet will include
six card readers, firewire and
USB connectors, a mouse,
a keyboard, SLR equivalent cameras
as well as serial and parallel ports
"some people" would have preferred something different - specifically a whole lot easier to use and less prone to malware. Almost no one claims to use more than ten percent of the functions of Word or Excel - hyperbolic cotangent anyone? The fact that people do not always want the same thing requires that companies build more than one thing - at least if there are any competitors to worry about. Microsoft's only real competitor was Apple and they were not much better. Their product - although easier to use and less prone to malware - was still only one version. It ran MS Office just like Windows. Notice that both companies dropped the easy to use and cheap or free versions of their office software - MS Works and Apple Works. They did have decent alternatives to the gargantuan MS Office but no more.
As we turn the corner toward mobile devices, my hope is that companies will not try to build the "perfect tablet" that meets the needs of everyone. If they do, it will include six card readers, firewire and USB connectors, a mouse, a keyboard with numeric keypad, SLR equivalent cameras (front and back), dual game controllers, as well as serial and parallel ports - hey some people still have that 1995 dot matrix printer to hook up. And of course it must run Excel, Word and PowerPoint using any remote device purchased since 1950.
In the case of tablets the smarter decision will be to either offer several models - one with and one without a keyboard - or one product that has options - such as docks we've used for years or the wireless keyboard approach on the iPad. The primary driving force for tablets is size, weight, convenience and ease of use. I'll be terribly disappointed if they evolve into dinosaurs as PCs have done. Adding layer upon layer of functionality was no problem with desktop computers - users could just buy bigger monitors so there was some place to see the actual words in their document. Ten inch screens, limited keyboards and slower processors that characterize tablets may finally reverse the trend away from mega-applications.
The new crop of ultrabooks notable for their lack of hard drive and optical drive but with the ability to run full versions of Windows or Mac OS represent another change in direction. They are distinguished not by new features but by features that are omitted - what a refreshing change. Now only if the next version of MS Office included a version of Word with five hundred commands rather than one thousand five hundred. The Apple iWork package may indicate the new direction for productivity software.
There are so many products, technologies and companies involved in the rapidly evolving tech market today, I thought it would be helpful to summarize some important facts in a simple table. I made a list of twenty-four products including computers and a variety of mobile devices and software - then added several service related factors such as shelf space and the cloud.
I created a table with eight leading vendors across the top to see how these vendors competed in the twenty-four areas. I think it's going to be difficult for companies to survive with only a handful of products - desktop PCs and laptops for example. You can click on the image below to enlarge the chart. Let me know what you think.
This array of communication technologies can be confusing but the basic idea is quite simple. These are all members of the family of Electromagnetic Waves. Other members of this family include
TV and radio signals
Microwaves in your oven
X-rays
Gamma rays (from radioactive decay)
Ultraviolet and Infrared rays
And the ever popular visiblelight rays in a variety of colors that surround us every day
The only difference in these waves is their frequency. If you could change the frequency of light rays, they might become microwaves and you'd be cooked like a hamburger when you turned on a lamp to read.
To communicate using electromagnetic radiation we have created devices like radio and TV transmitters coupled with sending and receiving antennas so we can hear or view the signals. Our antennas pick up all the signals and the tuner in a radio or TV set picks out a very precise frequency - 91.1 for example - so we hear a specific station.
Our cell phones have the capability to communicate using the parts of the spectrum listed in the title above. There is an antenna built into your cell phone for each type of signal it can handle. Obviously the 3G phone signal coming from a cell tower is included or it wouldn't be a cell phone. 3G means the third generation cell phone technology; 4G is coming soon. 3G and 4G signals are designed primarily for voice transmission but can be used for data if you don't have a wi-fi connection available. The other signals are designed for data but services like Skype allow voice signals to be be handled also.
Wi-fi signals are generated by a wi-fi router in your home, office, coffee shop or collection of devices in a city-wide system. 3G signals can be transmitted for miles but your wi-fi router only has a range of a few hundred feet. Your neighbor may be able to pickup your signal and use your Internet connection if she is in the right part of her house. Most modern cell phones can receive GPS signals from satellites eleven thousand miles above the earth (see "range" below). The GPS signal is not related to the 3G signals so a cellphone connection is not required.
Bluetooth signals are short range signals used so nearby devices such as a keyboard and computer or cell phone and ear piece can communicate. Even shorter range signals will be used by NFC - Near Field Communication system - being developed now for credit card applications. That signal can only be transmitted for an inch and a half; very low power indeed. Every signal differs from all others in two respects - frequency and amplitude (power).
The range a signal can travel is determined by its power - also referred to as amplitude. There are strict regulations on what frequency and amplitude someone can use to broadcast or transmit. A certain frequency can be used in one location by one radio station. That same frequency can be used in another distant city provided the strength of the signals are set so they don't extend into each others territories.
An entirely new system consisting of thousands of high-powered wi-fi towers is under development by LightSquared. These towers would blanket the US with high powered wi-fi signals for nearly universal Internet access across the country. There is controversy, however, because these wi-fi signals are very close to the frequencies assigned to GPS. and could interfere with navigation. This could be very serious since airline navigation systems are at long last being converted to GPS.
Computers are often associated with numbers and words but the new generation of tablets typified by the Apple iPad brings a whole new dimension to creativity. For those like me who are not artistic in the traditional sense, the ability to manipulate photographs with powerful, easy to use, touch screen apps is absolutely marvelous. Last month, I discussed a number of photo apps with some editing capabilities but whose main strength was taking pictures. This post describes some of my favorite among hundreds of apps that manipulate images although most can start with an available photo or take one using a basic camera function. My usage is limited to Apple iOS devices but many of these apps should be available on other platforms.
I won't spend a lot of time explaining whether the apps work on iPhone/iPods or iPads. That is easy enough to check out at the app store if you are interested. Certainly apps that work on images are most effective when they take advantage of a tablet sized device. However, there are some fun and useful photo editing tools for the small screen as well. Some of these apps are free while others cost $1-4.
Photo Studio, Photo Booth and Finger Design
With this background here are some of my favorites: Photo Delight allows you to eliminate all color from a picture except selected portions. I've shown examples before and the UI (User Interface) is perfect. There are several others that do the same thing but none I've seen with the elegance of Photo Delight Dynamic Light provides a number of stunning special effects as shown in the picture of Honolulu at the top right of this blog. Some photographs are meant to record an image as realistically as possible. Now with all the digital cameras we have plenty of "ordinary" photographs so apps like this can be used to create unusual images. Camera FX (iPhone) and Photo Booth (iPad) offer effects similar to the popular Photo Booth app on the iMac. You preview a number of fun house type images and snap a picture of one (or hundreds!) that you like. (These apps are really in the category of camera apps I reviewed last month but I did not have Photo Booth installed at that time.)
There was a time in the analog age when filters were made of glass and attached to the front of your lens. They came in various colors; polarizing versions eliminated glare and others provided special effects. For large lenses, the filters could be very expensive. Today most of these effects can be provided by software after the picture is taken - polarizing is a notable exception. Not only are software filters much less expensive, you can experiment with different filters and different settings instead of selecting one or two filters and snapping a picture on film - never to be altered again. Photo Studio (iPad and iPhone) and Perfect Photo (iPhone) are two apps with a collection of filters and other effects.
Photo Delight
Two things you almost always need to do to improve any photo are light adjustments and cropping. There are some apps that perform just those basic functions but many more powerful apps also include those functions.
Auto Adjust is an iPad app that concentrates on these basic functions. Filterstorm and PS Express provide a much wider range of adjustments. Photogene on the other hand provides numerous special effects without the basic lighting and cropping features.
Framed
For just plain fun, it's hard to beat Framed, Alien Booth and Photogoo. With the latter two you can waste hours making "interesting" pictures of your friends and family. Framed allows you to put your friends on TV, in a museum or on a milk carton among other places.
Finger Design does not process images but allows you to easily make a collage from your photos - original or edited versions. You can quickly select a background and arrange and resize any number of photos for display.
Finally, remember to check out my list of favorite apps and the places you can go to find apps.
