                            Windows 7 Hidden Treasures
                            Written by Sandy Berger, CompuKISS

If you recently purchased a new computer with Windows 7, you may not notice too many
improvements or new features. The fact of the matter is that Windows 7 is filled with great new
stuff. It's just that there is no manual to point out the new features. So you have to search
through and find them yourself. To give you a leg up -- here are some of the hidden treasures
that can be found in Windows 7.

Aero Snap
The Aero Snap feature is my favorite new Windows 7 features. In previous versions of
Windows, if you wanted to have two windows on the screen next to each other, you had to
manually resize the windows with your mouse. With Aero Snap, you simply grab the Title Bar of
the window with your mouse and flick the window to either side of the screen. It fills exactly
one-half of the screen. Flick another window to the other side of the screen and both windows
are visible and perfectly sized. This feature also allows you to click your mouse on the Title Bar
of any window and drag it to the top of the screen. This will maximize the window making it fill
the screen. Drag the maximized window down from the top of the screen and it will become
smaller again.

Snip It
There are times when you might like to take a picture of what is on your computer screen to
save or to send to someone. In Windows XP you have to use the Print Screen key to capture
the image. Then you have to paste it into another program to save or send it. Windows 7 makes
it much easier with a screen capture feature called the Snipping Tool. Click Start then type in
snipping and press enter or choose the Snipping Tool from the top of the list. A white overlay will
appear on your screen and a small Snipping Tool window will appear instructing you to Drag the
cursor around the area you want to capture. You can create snips with a rectangular mouse drag
or a free form pen. You can also snip the active window or the entire screen. Once you snag the
snip you can save it or send it to a friend right from that window. You can also add pen and
highlight markups. The Snipping tool is not completely new. It debuted in Windows Vista.

Sticky Notes
Sticky Notes have always been available as an additional program, but now the Sticky Notes
program is a part of Windows. Click on Start, type in sticky and press enter or choose Sticky
Notes from the top of the list. A new note will appear on your screen. Type in your note, and
then go back to what you were doing. The note will remain on your computer desktop until you
delete it. You can change note color, format a note's text, and resize and flip through notes as
you please.

There has almost always been a calculator in Windows, but the new Windows 7 calculator has
been completely revamped. There are now four modes: Standard, Scientific, Programmer and
Statistics. It is more useful than you might think. It can calculate the difference between two
dates, convert ounces to grams, Celsius to Fahrenheit, and joules to BTUs. It even has
templates for calculating things like mileage and mortgage payments. I write reviews for a
Portuguese website, so I often use it to convert product measurements and weights into metrics.
All-in-all, it's a very useful tool.

Device Stage
Device Stage is a visual interface that makes it much easier to interface with various
computer-connected devices. In previous versions of Windows when you attached a printer,
camera, or cell phone to your computer, it appeared as a generic device icon in My Computer or
the system tray. In Windows 7 these devices appear as an icon that actually looks like the
device. You can also get information about the device, services that are linked to the device,
and links to informational Web pages and user manuals. The amount of information that you get
depends on how much the manufacturer of the device has added, but many manufacturers are
doing an excellent job with this Device Stage area. When my Nikon camera is attached I can
click right from the device icon on the screen to transfer my pictures, read product manuals, and
shop for accessories. It will even show me the amount of battery power left in the camera.

When a new device is plugged in to your computer, it can usually be seen on the Windows
Taskbar on the bottom of the screen. Other devices can be seen by clicking Start, then Control
Panel, and choosing either the icon for Devices and Printers or Devices and Printers from the
Hardware and Sound area.

As you can tell, Windows 7 is filled with great features. If you already have a computer with
Windows 7, you may be propelled to start using some of these features. Or you may even
decide to buy a new computer just to get Windows 7. Now that's pretty exciting!

                             MP3 Tag - A Useful Utility
                  By Phil Sorrentino, President, Parasota PCUG, Florida
               / president (at)

As I have said in the past, "Utilities are usually small programs that are intended to do a specific
task or a small range of tasks." And I have also directed you to the SPCUG Monitor Computer
Buffet, where you can learn about various free utilities (and even find a website from where you
can download the utility). However, keep in mind that when you download something from the
internet, you could get something you were not expecting; so be very careful. With that said, I'd
like to discuss a free utility that allows you to modify the MP3 Tag information that is used by
MP3 players like Windows Media Player or iTunes.

The reason you might want to use an MP3 Tag utility is because these types of media players
depend on the Tag information to organize the tunes they find in your music folders. If the Tag
information is not what you expect, the tune will be put in a location that might make it difficult for
you to find. It doesn't matter what the file name is, the tune will be put in a sequence depending

DATALINE                                           3                                APRIL 2010
on the Tag information, only. Is it "The Beatles", or "Beatles", "The Kingston Trio", or "Kingston
Trio"? When I put all my tunes together, I found both versions of artist names. Also, sometimes
the tune comes from a compilation of artists. In this case it probably goes into the "Various
Artists" category, instead of the "artist's name" category.

MP3Tag is a free metadata editor that supports the MP3 audio format as well as many other
formats such as AAC, FLAC, MPC, OGG, MP4, WMA, and others. It runs under Microsoft
Windows XP and Vista (and probably Windows 7). MP3Tag allows the user to modify the ID3
tag data that is created along with the MP3 file when a tune is initially created, or ripped from a
CD. It allows information such as the title, artist, album, track number, or other information about
the audio portion of the file to be stored in the file itself. By the way, there are many MP3
Tagging utilities available, just Google MP3 Tag and you'll see all the possibilities.

This may be too much detail, but there are two unrelated versions of ID3: ID3v1 and ID3v2. (If
this is too much detail, skip this paragraph entirely.) ID3v1 was the original attempt at capturing
data about the tune. ID3v2 followed shortly after and is very different from the v1 version. ID3v2
is fairly complex, but suffice it to say that it includes all of the pertinent information, and then
some, relating to the specific tune. ID3v2 has been modified and improved over the past few
years and is currently at ID3v2.4. For those of you who asked "What the heck is metadata?,
here is a brief discussion that comes from Wikipedia. Metadata (or sometimes metainformation)
is "data about other data", of any sort in any media. An item of metadata may describe an
individual datum, or content item, or a collection of data including multiple content items and
hierarchical levels. In data processing, metadata provides information about, or documentation
of, other data managed within an application or environment. This commonly defines the
structure or schema of the primary data. For example, metadata would document data about
data elements or attributes, (name, size, data type, etc.) and data about records or data
structures (length, fields, columns, etc.) and data about data (where it is located, how it is
associated, ownership, etc.). Metadata may include descriptive information about the context,
quality and condition, or characteristics of the data. And there you have a description of

MP3Tag is very easy to use. First, I have created a folder called "FixThese" in my "MP3Music"
folder, where I put any tunes that I think need to have their ID3 tags modified. Then I setup
MP3Tag to use this folder. This way, I do my work in a specific folder so I don't upset anything in
the folders that contain all my music. Also, it is easier to work with a folder that has a handful of
files rather than thousands of tune files. (The folder to be used is setup by clicking "File" and
then selecting "Change Directory", then navigating to the directory of your choice,
"D:\MP3Music\FixThese" in this case.)

The MP3Tag window has two panes. The right-hand pane shows the files in the designated
folder. The left-hand pane shows each of the specific ID3 data items that can be modified. (By

DATALINE                                          4                                APRIL 2010
the way, default values can be setup for each of these items, but I have left the default to "keep",
so that I preserve the values when a tune is selected. These default values can be setup in the
Tools-Options-Tag Panel window.) When you select a tune in the right-hand pane, the
appropriate values show up in the ID3 tag items on the left. Once the tune selection is made, the
values on the left can be changed to your desired values. In the example shown above, the tune
"Ventures - Hawaii Five-O.mp3" has been selected. The Title is "Hawaii Five-O - The Ventures"
which is the file name. The title of the tune should be only "Hawaii Five-O", so I would change
the title to be such. The Artist: name is "Various - Adult" which I would want to change to
"Ventures", or possibly "The Ventures" if that is how you are referring to this artist. Other
information such as Album, Year, and Track may be correct as indicated and will probably be left
alone. Genre is an item that is not as well defined as the other tags and therefore I have found it
to be less useful. Genre has some general meaning but the meanings may vary a lot from
person to person. There are some fairly specific meanings for genre such as "Rock & Roll",
"Country", "Classical", but many other meanings are in the grey areas such as "Popular" and
"Easy Listening". If you want to employ this tag to any degree of usefulness, you'll have to make
your own definitions and then categorize all your tunes according to these definitions. Otherwise,
you'll get whatever the recording studio used for their definitions of genres. After you are
satisfied with the changes you have made, click "File" and then select "Save tag" or just click on
the icon that looks like a floppy disk, to save the tag information with the tune.

MP3Tag is a useful utility if you are accumulating a large music collection and you have some
specific ideas about how you would like the tunes to be organized. MP3Tag has a lot of
additional features. I have described the ones that, I feel, are basic to organizing a music
collection. Music collections have a way of growing in all directions and using an MP3 Tag utility
is a way of controlling that growth.

                The Best Free Software According to Gizmo

In these tough economic times, many of us are finding it difficult to afford new software for our
computers. Locally and on line we can shop and sometimes find some deals on software, but if
money is especially tight, some of us would choose to do without. Alternatively, there has always
been a huge assortment of free software or "freeware" available that can adequately accomplish
almost all computing tasks. While there are some mega-sites such as and that each carry thousands of software titles, many of which are freeware, there are
also some lesser known websites that provide comprehensive information and reviews about
freeware. One recent find that has now become one of my favorites is Gizmo's Freeware
Reviews, at

DATALINE                                         5                                APRIL 2010
Upon accessing the Gizmo
website, the user is greeted
with a graphical menu
containing 20 categories of
software, including cleanup,
educational, games, Linux,
security, programming,
security, system tools, and a
dozen others. In addition to
free software, Gizmo offers
additional categories of
information in its navigation
window on the left side of the
main page. These additional
categories include the Best
Tech Websites, How-to Guides and Tutorials, Freeware Updates, Security Advice Wizard, and
Video Tutorials, as well as some housekeeping functions.

Since I am very concerned about cyber security, I chose to open the Security link from the front
page graphical menu, one of the 20 possible selections. I was greeted with a listing of about two
dozen Gizmo articles on security software and related topics. Ranked in order of number of hits,
and indication of the popularity of each topic, the first security article is "Best Free Antivirus
Software", which has had nearly 1.4 million hits. Opening the antivirus article, the user is greeted
with a non-technical explanation of antivirus software, followed by a discussion of what Gizmo
has determined as the best of the many free antivirus utilities. Gizmo awarded Avira AntiVir
Personal Edition its top pick, narrowly beating out Microsoft Security Essentials, which is actually
Gizmo's personal choice. Each review is hyperlinked to a section farther down on the webpage,
called the "Quick Selection Guide" which summarizes the pros and cons of each recommended
product, download links, file size, latest version, 32 and 64 bit compatibility, installation tips, a
discussion forum, and online help. The other recommended antivirus products are Avast!, and
a-squared Free.

makes a recommendation of an antivirus product and a firewall. I tried the wizard using a variety

DATALINE                                          6                               APRIL 2010
of operating systems and levels of experience, and the wizard arrived at reasonable
recommendations for each. The user who follows the wizard's recommendations will likely be
well served by its picks.

In addition to having information and reviews on software products, Gizmo also offers a wide
selection of other helpful services and information. One that I found exceptionally useful and
interesting was a listing of PowerPoint slides and presentations, under the heading "Easily Find
PowerPoint Slides and Presentations Using This Site" at I do
a lot of PowerPoint presentations in a variety of settings and to different audiences, and often
have some difficulties coming up with material. Gizmo may be of great help locating material,
and one such resource linked on Gizmo is Slidefinder, at Available in 23
languages, Slidefinder has proven to be an outstanding resource, capable of locating individual
slides and complete presentations on thousands of topics. One of the most frequent PowerPoint
presentations that I do is on identity theft; entering the term "identity theft" in the search box
displayed Slidefinder's limit of 1000 items. Scrolling over the displayed slides (20 per page),
opens a larger image of the selected slide and also displays any notes integrated with the slide.
A link to the full PowerPoint file is also displayed, and a simple right-click on the file name and
selecting "Save Link As" will download the complete file. The primary source of the PowerPoint
slides and files are hundreds of universities from all over the globe, as well as government
agencies, organizations, trade associations, and other sources.

Another very beneficial section of the Gizmo website is the "Hot Finds" at This selection displays software deals, mostly free, offered by the
commercial software publishers for a limited time. As I type this, some of the commercial
software being offered for free includes PC performance enhancing utilities, anti-malware
utilities, backup utilities, graphics editors, and many others. Frequently checking this list may
provide the user with an occasional gem of commercial software either for free, or at a ridiculous
low price, such as a recent offer (now expired) for a top rated $30 anti-malware product available
for the paltry sum of 99 cents (I purchased 6 copies).

Many users sometimes need some help with accomplishing some computer tasks, or may even
find some tasks that may need to be performed that they may have been unaware of. Gizmo has
a "How-to Guides and Tutorials" section at, with over 50
topics listed. The most widely used tutorial "How to Make Vista Run Faster" has been viewed
over 300 thousand times. Other tutorials cover different browsers, backing up critical files,
improving performance, creating a bootable rescue CD, how to reduce spam, and many other
helpful and useful subjects. The Gizmo tutorials are presented in a readable non-technical
fashion that is easy to follow and implement,

Gizmo has a wealth of information available, including free software that has been reviewed and
evaluated, as well as tutorials and other valuable information. I subscribed to both the RSS feed
and email alerts so I can always be promptly informed of any new articles and software added to
Gizmo. Stop by and see what treasures that you might find

                            When is a dSLR Not a dSLR?
           By Jerry Schneir, Member of the Los Angeles Computer Society, CA
                / editor (at)

Simple question but very indicative of what the future holds for some of us photo buffs. In simple
terms, it is a camera that is devoid of a mirror box assembly. In other terms it is an
interchangeable lens camera, but unlike a single lens reflex (SLR) it does NOT have a mirror to
redirect the light from the lens to the optical viewfinder. All SLR cameras, digital and otherwise,
use a mirror assembly to intercept the light that comes through the lens and redirects the
incoming light to the viewfinder rather than to the film (or sensor) at the back of the camera.
Generally the light will also pass through a prism or fixed mirrors at the top of the camera on its
way to the viewfinder. It is this complex configuration that gives a SLR a distinctive look. It is also
this configuration that gives a SLR a distinctive sound as the mirror swings out of the path of the
incoming light and then returns to redirect the light back to the viewfinder.

To answer the question we need to go back in time. The entire dSLR world started changing in
September of 2004 with Olympus's introduction of their E300 dSLR. Here was a camera that
didn't look quite like anything else, not SLR nor rangefinder. It sported a mirror that worked
different, didn't have the traditional top bulge and was based upon the Four Thirds sensor
design. In September of 2005 Olympus came out with their E500 a dSLR looking camera and
then in January of 2006 they introduced the E330, another dSLR type, but a camera with "Live
View", the ability to see the image on the LCD before the shot was taken. That feature caused
an uproar among the traditional SLR manufacturers.

In February 2006 Panasonic introduced their unique looking L1 which was also based upon the
Four Thirds sensor.. While the L1 still incorporated a mirror it did not have the look of a SLR, but
more closely the rangefinder cameras of the `1950-1960 period. That camera bombed primarily
because of cost. In August of 2007 Panasonic introduced the L10 which now resembled the
traditional look of the SLR and had Live View but again did not do as well as hoped for by

In September of 2008 Panasonic brought forth the G1 a Micro Four Thirds camera that looked
like a dSLR in that it had the characteristic bulge on the top of the camera, had interchangeable
lenses, but it did NOT have a mirror box assembly. In the GI, light passed directly through the
lens onto the imaging sensor. This was a much different camera. The camera was different for
several other reasons. It was based upon the Four Thirds sensor size introduced several years
earlier, but used Micro Four Thirds mount lenses, and used an electronic viewfinder (EVF) in
place of the traditional optical viewfinder of the digital single lens reflexes (dSLR) cameras.
Though it looked like the smaller dSLR cameras, Micro Four Thirds cameras are not dSLRs.
They are also smaller because they don't house a dedicated autofocus image sensor. The

autofocus on the G1 uses the Four Thirds image sensor. This is exactly like autofocus on a
compact camera. But here, autofocus is speedier because on the Micro Four Thirds cameras
they use both a faster autofocus algorithm and a faster processor. This makes autofocus feels
faster and more like a dSLR, at least on some cameras.

Up to this time, two companies, Olympus and Panasonic had adopted the Kodak developed Four
Thirds sensor design. The major advantage, and to some old diehards, the only advantage, was
the reduction in both size and weight of the lenses and to a certain extent, the size and weight of
the camera body as well. But these earlier cameras although smaller and lighter in weight, still
could NOT do what every point and shoot camera could, show the image on the LCD or EVF
before taking the picture and shoot movies. The GI still lacked the movie ability. The movie
mode was just peeking its head up in regular dSLR at about that time with "Live View".
Panasonic changed that with the arrival of the GH1 in March 2009, a new movie mode had been

Up to this point in time, all these cameras still utilized the mirror box, nothing really had changed
until the earth shattering (somewhat an exaggeration) introduction of the new mirrorless cameras
in 2009, the Olympus E-P1. This was a rangefinder looking camera, albeit, without a rangefinder
but having the rangefinder look. However, this breakthrough camera lacked two important built-in
features, no flash and no viewfinder of any type. Olympus partially corrected this "whoops: with
the introduction of the E-P2 in November 2009. This camera had a port for connecting a high
resolution EVF. In February of this year, Olympus announced its newest edition to this family, the
E-PL1. This camera had a built in flash and a port for connecting the EVF.

Panasonic finally took the plunge into a rangefinder style camera with the introduction of the GF1
in September of 2009. The GF1 uses an optional EVF and has a built-in flash unit. In March of
this year, Panasonic announced two new cameras, the G2 and the G10. These are almost
identical cameras resembling SLR designs more than anything else. Interchangeable Micro Four
Thirds lenses but no mirror boxes.

But this question about dSLR cameras doesn't end here, other cameras with interchangeable
lenses but lacking a mirror box have been introduced, have been announced, or are rumored to
be in the works. I have deliberately skipped talking about Leica cameras since, IMHO they are
just largely rebadged Panasonics. Sony showed their non-working prototype based upon a full
APS-C sensor. Ricoh's GXR comes with interchangeable units containing a lens and a sensor in
a rangefinder style camera. Can't say much about the sensor size since it is dependent upon the
lens that is part of the system. I have strong reservations about this concept.

The Samsung NX10 is a rangefinder style camera using a new lens format called NX. What is
most interesting about this camera is that it uses a APS-C size sensor, that is about 1.5x that of
the Four Thirds sensors. Of course, this means larger and heavier lenses than that of the
Panasonic or Olympus cameras of similar designs. While Canon and Nikon have said nothing,
rumors are rampant. I suspect that we will see new mirrorless digital cameras from these
mammoths of the industry in the later part of this year. I suspect that the designs will be that of
rangefinder styles reminiscent of earlier Nikon RF cameras of the 1940-1960 and the same with
Canon except they may base it more on their popular G series of cameras such as their G11.

So here we have it, a whole new class of cameras, you might say SLR cameras minus the R. I
prefer to say RF style since in my mind they are truly reminiscent of cameras from the 1940-1960
time period. The advantage to this new group of cameras is smaller size and lighter weight while

maintaining the excellent image quality associated with the dSLR cameras. Disadvantage, fewer
lens choices and, for the time being, relatively more expensive. Some of these cameras tend to
be slower focusing but that is changing in the newer models.

If you are bent on getting an iPad don't read any further. However, if you are trying to decide
between buying a laptop and an iPad this article is for you.

I like my laptop because I can load any software, connect any device such as a digital camera,
memory stick, and backup drives by USB connections. I like the idea of being able to load free
software from any company or source and not be restricted to one company such as Apple.

"Your computer should be yours to control," said Peter Brown, the Free Software Foundation's
executive director. "By imposing such restrictions on users, Steve Jobs (APPLE CEO) is building
a legacy that endangers our freedom for his profits (The Microsoft Blog)."

For me, choosing a laptop is simple: Macbook. I run Windows XP and Windows 7 on my Mac
laptop without a glitch. Of course there are many other laptops, notebooks and net books that
work great too and all of them avail you the opportunity to install third party applications, many at
no cost.

The iPad has landed in                                              North America and is creating
huge hype. Rightfully so! It                                        is a wonderful device allowing
for various functions.                                              According to Wikipedia, the
iPad "is part of a device                                           category between a
smartphone and a laptop                                             computer." This may be true but
it is not close to my                                               Macbook laptop, not by a long

For starters the hard drive                                    is only 16 to 64 gigabytes (GB)
of flash memory (a                                             technology that is primarily used
in camera memory cards). My laptop is 250 GBs and with a terabyte hard drive connected by
USB; I now have a grand total of 1274 GBs of hard drive space. Very different from 16 to 64
GBs of the iPad.

The iPad's 9.7-inch (25 cm) screen has a low-end resolution of 1024 X 768. What this tech talk
means is that the iPad will not support HDMI video which many have come to love. With high
definition the rave...Why go back to a lesser screen resolution. This does not make sense.

Other features lacking in the iPad are: no camera, no webcam, no multitasking, no drag and
drop file management, no USB port, no SD slot, no Flash, no HDMI out, no 1080p playback, and

no native widescreen. Are we going backwards here? In 2005 it was "the Year of High Definition
Video," according to How come the iPad lacks these features?

Many are saying the iPad has its neat functions and is esthetically appealing. Just make sure
you are getting the exact features you require in any tech device. Do your homework on this one.

 Defragmenting your hard disk is a great way to boost the performance of your computer. Though the
 term "defragment" sounds a little abrasive, it is actually a simple and helpful process. After all, a
 defragmented hard disk is a happy hard disk.

 Adding and deleting files from your hard disk is a common task. Unfortunately, this process is not
 always done very efficiently. For example, when you delete a bunch of little files and add a new large
 file, the file may get broken up into mulitple sections on the hard disk. The computer will still read the
 newly added file as a single valid file, but the drive will have to scan multiple parts of the disk to read it.
 Because hard disk seek time is one of the most significant bottlenecks in a computer's performance,
 this can drag down your computer's speed quite a bit. If you have a ton of "fragmented" files on your
 hard disk, you might hear extra grinding, sputtering, and other weird noises coming from your computer.

 You computer does not like having fragmented files any more than you do. This is why defragmenting
 your hard disk is such a good idea. W hen you start to hear extra grinding sounds, or your computer
 doesn't open files as quickly as it did before, it's time to defragment. W ith W indows, you can use the
 pre-installed Intel defragment program to defragment your hard disk. You can also use a commercial
 software program like Norton Utilities to defragment your hard disk more efficiently and with more
 options. For Mac users, a disk utility such as DiskW arrior or Tech Tool Pro is the only way to do it. If you
 use your computer daily, defragmenting your hard drive once a month should keep the fragment-fiends

We know that a GPS (global positioning system) device is best used to help you get from point A
to point B in a timely fashion. And now, some new GPS devices feature a built-in cellular modem
for accessing Internet features, giving you real-time maps and up-to-the-moment traffic updates.
Additionally, you're able to check local gas prices, which is a helpful feature whether you're
searching for a gas station in an unfamiliar area or you want to find the best nearby price for gas.

With a connected GPS device, you can also email maps and directions to your GPS via a home
or office computer, which is convenient for adding mapped itineraries to your GPS. Additionally,
some Internet-connected GPS devices are also equipped with a local search function, meaning
you can search for hotels, ATMs, and free Wi-Fi hotspots in real time rather than accessing POI
(point of interest) data.

Standard tripods are best for taking long exposures or night shots when you need to keep the
camera completely still while capturing a one-of-a-kind shot. A tripod would also pair well with a
remote switch to eliminate camera shake and help you steady your camera on uneven surfaces,
especially in outdoor shots when you need to position yourself on a precarious hiking trail
halfway up a mountain. A tripod will give you the freedom to capture creative landscape images
using slow shutter speeds or swappable lenses. Tripods are also compatible with camcorders,
allowing you to film your family making memories without a jerky final product.
