October 2008
Because the City of Napa has decided to replace
the roof of the building we meet in there will be no
October general meeting. I really don’t know why
this should affect our night meeting time?
I personally was looking forward to this meeting.
Earlier this year I asked Susy Ball to try and arrange a presentation about
online banking. There are many people that believe it is less safe than
other methods when in fact it is actually a safer way to bank. Thousands
more identity thefts result from “dumpster diving” and paperwork theft
than result from any online transactions with your bank. In fact I am not
aware of any online transaction between a customer and their bank that
resulted in a fraudulent loss. I have asked Susy to reschedule this
presentation for early next year.
Normally the NVPCUG Board of Directors would get the majority of
board nominations at the October general meeting. The board will vote
for the 2009 Board of Directors at the November 5, 2008 Board of
directors meeting so we will not have a chance to hear from the general
meeting attendees. Because of that I am asking any dues paying member
who wants to nominate a member to serve on the 2009 Board of
Directors e-mail that nomination to [email protected] before
November 4th.
I have also suffered a back injury that is affecting my sciatic nerve. I
apologize if I have missed any e-mail you sent and have not been active
in responding to member’s questions or concerns. I cannot sit at my
computer and weed through the thousands of e-mails I receive weekly
and pick out the valid from the spam. I presided at the October Board of
Directors meeting by standing up. This message has taken me several
days to write sitting and writing for only a few seconds at a time. I hope
this issue is resolved quickly.
Have a fun Halloween and I will see you at the November 19th general
meeting.

According to the data from the International

than 2 billion cell phone or mobile phone
subscribers. While the 20- and 30-somethings are
flocking to the iPhone as the latest status symbol,
the 40-, 50- and 60-somethings are acquiring
iPhones because there are no tiny buttons and no
complex menu systems.

Excel Shortcut
If Excel doesn’t load when you double-click its
shortcut, don’t worry. Sometimes Desktop shortcuts
(or even those in the Start menu) become corrupted
and no longer point to their associated EXE
(executable) file. To see if that is the source of your
trouble, click an empty area of your Desktop and press
F3 to launch Windows’ search feature. Type Excel.exe
into the file name field and press ENTER and then
double-click the file’s icon when it appears in the
results pane. If doing so launches Excel, you know
that your shortcut is corrupted and causing the problem.
Simply delete the bad shortcut (right-click it and click
Delete) and right-click and drag the Excel.exe file
icon that you found to where you’d like a new shortcut.
When you drop the icon, a context menu will appear;
click Create Shortcuts Here, and your new shortcut
will appear.
Clean Your DVDs
DVDs are best cleaned with a lint-free, nonabrasive
cloth. Dampen the cloth in clean, lukewarm water. (If
your water is especially hard or contains excess
minerals, use bottled water.) Starting at the center of
the disc, wipe in a straight line to the outside rim; don’t
use a circular motion. Repeat until you’ve cleaned the
entire disk. For very stubborn messes, try water with
a mild, nonabrasive soap or isopropyl alcohol.
Commercial DVD cleaning solutions are also available.
Never use compressed air to blow a DVD clean.
Compressed air can be very cold and may thermally
shock the disc, causing separation or cracks, either
immediately or down the road.

System Mechanic 8 –

Frequent readers of this column
will be well aware that there are
many computer utilities in
cyberspace that can improve the
performance of our PCs. As we
use our computers, the registry
becomes
cluttered
and
inefficient; useless files consume
valuable real estate on our hard
drives; and other maladies caused
by the software on our computers
deprive us of the performance
we paid for and deserve. While I
admittedly use several different
utilities to maintain peak
operating efficiency of my
computers, if I had to choose
only a single utility for computer
maintenance, it would be Iolo’s
System Mechanic (www.iolo.com). I have used System
Mechanic for many years in its earlier versions, but now
Iolo has released the latest iteration, System Mechanic
version 8.
Simply, System Mechanic 8 is arguably the most
comprehensive PC maintenance utility available, with
over 40 distinct performance and security tools included,
giving it “Swiss Army Knife” features. According to
published sales figures, System Mechanic is the #1 best
selling PC tune-up software on the market, and has won
awards for excellence from dozens of computer
publications, including Cnet’s Editors’ Choice, Windows
Magazine, PC Computing, ZDNet Editors’ Pick, Computer
Shopper’s Top 100, Computerworld, and many others.
Rhetorically, why would I choose System Mechanic 8
over all of its competitors? Because of what it does, its
power, versatility, and features; that is why. Compared to
its major competitors, none of them offer the feature rich
set of functions that System Mechanic offers. According
to Iolo, “Over 98% of PC problems are caused by clutter
and faulty settings that are the result of everyday PC use.”
System Mechanic 8 can repair or otherwise remedy virtually
System Mechanic 8 Review cont. on page 8
NVPCUG Computer News, Oct 2008, Page 7

all of these problems.
Many of a PC’s problems
can be traced to problems
and errors in the registry,
a large data file that
contains information on
the hardware and
software installed on the
computer. The registry is
almost constantly written to, and read, often leaving
obsolete data in the registry. This obsolete, and eventually
erroneous data left in the registry consumes some system
resources, and can promote errors and other problems as
faulty data is read and processed. The registry must be
periodically purged of useless data, defragmented and
compacted in order to contribute to better PC performance,
a function at which System Mechanic 8 excels.
Our computers are constantly reading from and writing
to the hard drive, and that drive often becomes cluttered,
fragmented, and may also have some errors in the data
stored on it. While almost all flavors of Windows have
some type of “defrag” and “chkdsk” software to
defragment the hard drive, and check it for errors, the
Windows integral versions of those utilities are very
basic and lack the power to do a truly thorough job, as
System Mechanic will do. Clutter and useless files
consume a lot of the storage space on our hard drives;
System Mechanic 8 can identify and remove that clutter,
freeing up that hard drive space, making for a more
efficient hard drive.
Sometimes, and it will likely happen eventually to
each PC user, the computer will not properly boot. For
that particular eventuality, System Mechanic 8 will allow
the user to create a bootable emergency CD that may be
able to revive “crashed” systems. Another irritant that
many of us suffer through on a regular basis is the
boringly slow boot process itself, where we wait and wait
for our computer to become usable. System Mechanic 8
claims to have 19 different ways that it can speed the boot
process by making it more logical and efficient. Another
way that we are losing performance that we are paying
for is by having improper internet settings. Many of
these settings are mundane and not readily accessible to
the typical user. By modifying these settings to their
ideal point, internet throughput can be improved, in
some cases tripled. System Mechanic 8 will analyze our
internet connection, and make any changes necessary to
maximize performance.
PC security is a major issue that all of us must deal with
on a constant basis. System Mechanic 8 contributes to
system security by fixing settings that would otherwise
allow an intruder to access the computer, making cyber
attacks that more difficult. Sometimes we have files that
we want to securely delete, being well aware that normally
deleted files are easy to recover, which may create
another security problem. This utility offers the user a
military grade wiping function that can securely delete
unwanted data.
System Mechanic 8 retails for $49.95 for a one-year
license, and can be used on up to three computers;
discounts are available online (www.iolo.com)
for longer licenses.
For those who want an even more feature rich product,
Iolo offers System Mechanic Professional, version 8 ($69.95
for 3 computers). This Professional version is an integrated
bundle which includes most of Iolo’s other popular
products. The bundle includes Iolo’s antivirus software,
renowned for its hourly updates; and its Personal Firewall
to protect from intruders and malicious software. Another
program included with the Professional bundle is another
personal favorite of mine, Iolo’s Search and Recover. This
program can recover files that were deleted, including
photos, videos, documents, email, music, and other data
that may have otherwise been lost. Search and Recover
can undelete files from hard drives, digital cameras,
memory cards, and almost all other digital media.
Professional also includes DriveScrubber, a utility that
can securely erase data from hard drives. This is necessary
when donating a computer, selling it, or recycling it.
Without securely deleting our personal data, others can
access it and use it for a variety of purposes, including
identity theft. DriveScrubber overwrites the data using
methods that meet strict government and military
standards, ensuring the destruction of that data, without
harm to the drive itself.
iolo has a winner in System Mechanic 8. For those who

The third of these services is Zoho Office. On their home
page you not only find a list of the services they provide,
they are all available for trial simply by clicking on a icon.
As with the previous services, the list of applications is
quite extensive.
Google Apps is very similar in its offerings to the
preceding services. However, it is more oriented towards
business users. It does have a free version which might be
useful for the individual user.
Zoho uses Java to run its applications on the web. Other
services may use Flash or Java. Either of these allow the
applications to run in your browser and to operate at
reasonable speeds. I have tried out the word processing
and found it to be no different than using a word processor
on my computer. This is true even though the speed of my
Internet connection is usually only 500 – 750 kilobits/sec.
When you are using a wireless card modem it is only on
very rare occasions that you can match fast DSL speeds.
I’m sure that those of you on cable or fast DSL would have
no problem using a web-based application, at least with
regard to the speed of the applications response. However,
if you are preparing a graphic loaded presentation, then
you might experience some slow down depending on the
speed of your connection.
The idea of relying on Web-based applications and
storing data in the “cloud” of the Internet has long been
pushed as a way to do business on the road. Now
software companies are making entire Web-based
operating systems. They present themselves as a
complete computer in the cloud and are aimed at a wider
audience. These browser-based services could help those
who can’t afford their own computer.
There are also those who are convinced that this is the
future of computing. However, some security concerns
should be considered. Unless you know how secure your
data is when you use a cloud system, you should be
cautious about what you share with the on-line servers.
You need to know how your data is protected from other
users of the “cloud”. As a service provider they should be
willing to undergo external audits and/or security
certifications. Also you need to know what kind of data
protection and data recovery procedures are provided. As
has been demonstrated many times, computers do fail.
Finally, you need to know what happens to your data in
case the company fails or is sold to another entity. This is
also not uncommon in the high tech industry. As is always
the case, before allowing sensitive information to be used
or stored on the web, remember “caveat emptor”.
Lastly, consider what computing might be like should
the “cloud” become the method of choice. Certainly there
would be no need for computers to have all the bells and
whistles we now associate with them. Just think about the
possible design of a system destined for use solely with
cloud computing. It would only need a minimal operating
system that would allow the computer to boot, then start
the web browser which would connect to the Internet.
Your cloud page would be your home page and display
your chosen desktop. As for a hard drive, a 10 - 20 gigabyte
solid state drive would probably be adequate. USB ports
for printers, scanners, possibly other I/O ports would be
included. The one thing you would want to be high end
would be the graphics system. This would allow display of
high resolution graphics used in online games and for
viewing videos. It is possible that the graphics processing
unit (GPU) would be more powerful that the CPU (central
processing unit) or it might even incorporate the CPU.
This could all be contained in a 1-2 pound laptop or
compressed further into a handheld computer/cell phone.
Although some of these characteristics are found now in
smart phones, the spread of cloud computing would
enhance the features of these phones. For most of us, the
available screen size on these smart phones is not large
enough, leaving a market opening for inexpensive laptops
such as the ASUS Eee PC or the OLPC (One laptop per
child). In neither case would we need an operating system
as massive as Microsoft Windows.
One thing is certain, anytime you try to predict the
future you usually miss the mark by a mile. So it will
be interesting to see what reality brings about over the
next few years.

I am fond of saying that Google indexes only the

where we want to go. By way of caution though, I will say
that just because we find something lying around on the

reader is at least partly responsible for respecting copyrights,
particularly if you intend to redistribute or use that material
in any other way beside your own personal enjoyment. For
an excellent copyright primer that is targeted toward teens,
see h t t p : / / w w w . l o c . g o v / t e a c h e r s /
copyrightmystery/.
Even a relatively small university such as our own WKU
has a truly massive web presence, and in order to filter out
everything but E-texts, we need a flexible search engine
that has the power to filter results based on file types.
Google more than fills the bill.
Some of you may remember a while back we hosted a
presentation featuring Google’s keyword filters. For
NVPCUG Computer News, Oct 2008, Page 11
Global University cont. from page 11
There is one additional search filter in Google’s bag of
tricks that will help you find more E-texts and multimedia
lectures than using the filetype filter alone, and that is the
intitle:”index.of” filter. Intitle looks for the specified
keyword after the colon, in a web page title. Looking for
the keyword “index.of” allows you to hunt down
information-rich index pages, which can be thought of as
the best place to go for E-texts and recorded lectures on
university web sites because, as the name implies, they
are like a table of contents.
As an example, let’s Google using these keywords:
site:.edu
intitle:”index.of”
(mp3|mp4|avi) lecture
The vertical bar symbol between those file types is
called the pipe symbol—it is over your backslash key,
which is itself located just north of your Enter key. The
pipe symbol, in this context, means to search for “index.of”
entries that have either mp3, mp4, or avi in their text. This
search yields the following—the first of only 48 links (see
image at the end of article).
It’s not really that surprising that using the MP3|MP4|AVI
filter only finds 48 links—after all, there is considerably
more concern about copyright issues when looking at file
types that might be used to contain music, movies and the
like. Just for the heck of it, though, I tried this search:
Intitle:”index.of” mp3 beatles
The resulting search was impressive at finding mp3
files of the Fab Four’s recordings, but the webmasters
behind the pages it found were equally impressive at not
letting you play the files without paying for the privilege,
and since most of this music is copyrighted, that is only as
it should be.
Even so, using the intitle:”index.of” filter is extremely
effective at locating E-texts, particularly when combined
with the site:.edu filter to only search university and
college sites.
So your best bet on Google to find general E-texts is:
intitle:”index.of” _______
And just fill in the blank with whatever subject you’re
interested in. I used intitle:”index.of” caves and got 315,000
hits, the very first of which was a really cool teaching site
(http://erg.usgs.gov/isb/pubs/teacherspackets/exploringcaves/pdfindex.html) about
caves from the US Geological Survey.
I wish I could give you an idea of what intitle:”index.of”
is actually filtering for. If you can imagine the internet
functionally layered, like a Broadway production; got
that picture? Okay, searching the WWW with Google
using plain old normal keywords with none of the fancy
filters we’ve talked about here—will lead you to find hits
on what’s going on about the stage and the actor’s names
and so forth. Now Intitle:”index.of” comes looking, and
isn’t interested in the play, the credentials of the performers,
the lighting—nothing on the stage. That little but critical
filter ignores all of that stuff, but instead searches behind
the scenes, finding hits at the level of the executive
producer, the writer of the screen play, and where they all
went to school. That analogy is reaching a bit, but suffice
it to say that specialized filters yield specialized results.
Please share your E-text searching successes!

Most manufacturers carry pixel-defect policies

pixels are dead (show no color at all) or lit (stuck
in the “on” position so that they constantly appear

however, perhaps the retailer will. Other than
that, there’s very little you can do to fix this type

Picasa web album
In June I took a brief
vacation with son, Mike
and cocker spaniel,
Bonnie, touring scenic
central West Virginia.
We visited the stark rock
outcropping known as
Seneca rocks, admired
the amazing 110-meter steerable radio telescope at the
green bank national radio astronomy observatory, and
found carnivorous plants in their natural habitat in the
cranberry glades botanic area. Together we took over 400
pictures along the way that we culled down to 60-some
upon our return. It is often said that the secret of great
photographers is that they take hundreds of pictures but
save only the one or two best ones. Nobody ever mentions
how hard it is to pick out those few winners!
I decided to try and upload the best pictures to one of the
online free photo albums. I was already somewhat familiar
with Flick’r, but I decided to try the Google-Picasa web
album instead. Picasa is an excellent simple photo editor
and it gives direct access to the online web album. The
album allows 1gb of storage, enough for some 4000 pictures,
and you can get even more than that for a small fee.
Since I already had a
Google email account,
setting up the web
album was easy, using
the same user name and
password. On the web
site you can set
up separate albums
(folders,
really)
to store pictures in
separate categories. I
created a new album
for my vacation pictures and prepared to upload them.
After some trial and error I found it easiest to first
assemble the captioned pictures in a Picasa album on
my pc and then to upload them all at once to the web
album. Once the pictures are uploaded you can add
more or delete mistakes, move them around into the
desired order, and add or change captions. By default,
the photos are automatically converted to the optimum
size for display on a computer screen, but there are
options for larger (up to 20mb) or smaller file sizes.
Once the album has been installed it is ready to be shared
with the rest of the world. You may choose to make your
photos public, available to anyone, or keep them private,
only accessible to those you share the URL with. The view
album page shows large thumbnails of the photos. They
can be viewed individually or as a slide show. The view
map button brings up Google maps where you can indicate
where you took your pictures. The Organize and Edit
captions buttons are self-explanatory. A new features link
at the top of the page leads to the latest features added. It
is now also possible to upload videos from Picasa to your
web album. That might be preferable to using YouTube,
unless you want the whole world to admire your movie.
The web album displays the URL of your album site
either as the address itself or as a short paragraph of html
code that you can insert on your web site. Either way, it is
best to copy and paste the information since the URL tends
to be lengthy and confusing. My vacation pictures are
located at http://picasaweb.google.com/
swipcug/westvirginiavacation
june2008?Authkey=kovcoyrboay.
To do your correspondents a favor you should convert
the URL with SNIPURL (http://snipurl.com) or
TINYURL (http://tinyurl.com) to a simpler
address, such as http://snipurl.com/pimspix.
If you have never done that before, you’ll find it easy to
do. Just go to http://snipurl.com (or the TINYURL
site) and paste the URL of your album in the box. Specify
an easy-to-remember nickname (such as “Pimspix,” but
only available in SNIPURL) and “snip it!” the shortened
URL (http://snipurl.com/pimspix) will be
shown and also copied to your clipboard, ready to be
pasted in your message.
Gathering CLOUDS
My experience with setting up a photo album “somewhere
up there” is a typical example of the current trend towards
“cloud” computing. Almost since the beginning of the
world wide web we have been using online search engines
that access indexed information stored “somewhere up
there.” many of us have changed from our pc-based email
programs to online programs, such as Yahoo or Google
Mail, that store our email correspondence on computers
“somewhere up there.” somewhere up there in the clouds,
as it were.

The New, Best AND Worst cont. from page 14
The push is now to extend cloud computing to
office suites. Instead of using expensive ms office we
can choose to use Google docs and conduct all our
administrative activities online, with the option of
sharing our work with colleagues far away if necessary.
Microsoft, always ready to recognize good ideas
after others first thought of them, is moving versions
of its office suite online under the “live” banner.
Others are jostling to join the crowd.
If this trend continues and spreads to other computer
activities, our operating systems, whether windows,
Mac, or Linux, will become less and less important.
The functions of the operating system will be taken
over by browsers. To those of us using multiple
operating systems, such as windows and Linux, we
already find that it makes no difference if we use
Firefox in windows or Linux. Similarly, Picasa is
Picasa and my new web album is the same no matter
how I access it.
So far, that all sounds good. But gathering clouds
threaten to bring rain. If everybody is going to use the
Internet almost all the time, the current Internet
infrastructure will not be able to keep up. There will
be a need for millions of additional servers and
drastically increased connection speeds.
The computer industry is aware of that. According
to the Economist (May 24, 2008) Microsoft is building
a new $500 million data center near Chicago. It will
require 3 electrical substations with a total capacity
of almost 200 megawatts. Google is said to have 3
dozen data centers with an estimated million individual
servers. More and more these extensive data centers
are being built in out-of-the-way places near sources
of low-cost power, even in Iceland with cheap
geothermal power. With all this power consumption
computers are becoming a major source of global
warming.
To increase transmission speeds the industry is
eying the airwave bands that will be freed up in
February 2009 when analog TV will be phased out.
There are so-called white spaces between the
frequency bands assigned to TV broadcasts, and tech
companies want to use those buffer zones for lightningfast data transmissions. Initial tests show that it might
wipe out nearby HDTV broadcasts, but they keep
working at it. (Scientific American, June 2008)

Cell Phone Battery
If your cell phone battery doesn’t seem to hold its
charge long enough, you may be able to adjust your
phone’s settings to conserve energy. BlackBerry users,
for instance, can program their devices to turn off
automatically during certain times of day. To do this,
click the Menu key, choose Options, then select Auto
On/Off. From there you’ll be able to set the times at
which it will automatically turn on and off. There is
one setting for weekdays and another for weekends.
Another way to extend your battery life is to turn
Bluetooth off when you’re not using it. Keep in mind
that for optimal battery life, you should let your
battery run almost all the way down before recharging.
If your phone won’t charge up at all, try cleaning the
contacts of your phone and battery. If that doesn’t
help, try a new battery and/or charger. If a new battery
and charger don’t solve the problem, the issue is with
your phone and you should contact the manufacturer.
Headphones
A runner sometimes doesn’t fare well with earbuds
when using an MP3 player. They fall out due to the
constant jostle of running, and this can become a
burden for anyone hoping to get in a good workout.
It’s essential to match your earphones to your needs,
or your experience will be diminished. A runner
should opt for a headphone that’s secure, and in this
case, an in-the-ear earbud would be the ideal choice.
Headphone styles are numerous and include wired/
wireless earbuds, which are perfect for people on the
go (students, mass transit users), and earcups, which
can satisfy any audiophile’s need to hear minute
musical details.
Don’t Supersize
We’ve all run into the problem of not being able to
view an emailed image because it took up more than
the entire screen. To make emailing pictures easier on
you and your recipients, use the resizing tools in your
photo-editing software. To resize images in Jasc Paint
Shop Pro 9, for instance, click Image and Resize,
change the Pixel Dimension values, and click OK.
Not only will resizing your photos make it easier to
email them, but also it’ll make archiving and printing
them more simple. Look for a resize option in your
editing program’s tools or check to see if you’re given
advanced options when saving photos. Keep in mind
that the format you choose when saving photos will
affect the quality of your photograph. Naturally, the
higher the quality you select, the larger the picture file
will be.

As I mentioned last month, Vista’s Service Pack 3 is out.
I didn’t see any real changes in my computer after I
installed it, most of modifications are supposed to deal
with computer security. I have since encountered a problem
with my printer.
I don’t print too often from my “Vista computer” so the
problem wasn’t immediately obvious. When I did try to
print some documents they “disappeared” without printing.
My first thought was that I had changed the firewall on my
print server and locked out connections from other computers
on my home network (I’ve done that before). No that wasn’t
it. After checking and finding that I could transfer files
between my computers, I went to the printer section of my
control panel. That’s where I discovered that Vista wanted
a new printer driver installed. I don’t remember any problems
with the printer when I started using this computer. As I
recall, Vista recognized my printer (a fairly new HP ink jet
printer) and it just worked. Anyway, a search of Hewlett
Packard’s web site didn’t reveal a new printer driver. In fact
it told me to use the one built into Vista. I turned to the
installation CD that came with the printer and reinstalled the
printer driver from the CD. It worked and I can print over my
home network using a wireless connection again. I have no
idea why this happened but at least one other TAPCUG
member also discovered a printer driver problem after
installing Vista SP1.
Speaking of security (see paragraph 1), Windows Vista,
like Windows XP, comes with a firewall program preinstalled. As all you computer gurus know, a computer
firewall is a hardware or software tool that examines all
Internet traffic letting only “safe” traffic into your computer.
The firewall for Vista was supposed to scan Internet traffic
both entering and leaving your computer. I can hear some

of you saying, “If I scan incoming traffic to be safe, why
do I care about outbound traffic?”. Well, incoming traffic
is the bigger threat to you. Using pre-defined rules it
determines which programs are allowed to use your network
connection or which ports can be used for communications.
If some spyware, Trojans or malicious “phone home”
software slip past your firewall they may allow someone
to take remote control of your computer to attack it other
computers through your Internet connection (that’s why
Microsoft is always sending you those security updates).
So a firewall that scans outbound traffic attempts to stop
this. To make a longer story short, contrary to plans, the
ability to check outbound traffic has not been provided
with Vista’s firewall.
Another shortcoming of Vista’s firewall is that it does
not create a log of all attempts to contact your computer
from a local network or the Internet. This kind of record
can be useful if you suspect a hacker has been visiting your
computer in the middle of the night. Actually, there is a
way that you can modify Vista’s firewall to create a log and
examine outbound traffic. The process to set this up is
probably more complicated than most of us would like to
deal with so I offer a much easier solution. Turn off Vista’s
firewall and install a third party firewall program. Do not
try to use two or more firewall programs at the same time.
They do not play well together. There are a number of
firewall programs that you can purchase as well as some
that are free. I’ve been using the free version of Zone
Alarm for many years and I’m satisfied with its protection.
It also creates a log that I can use to examine attempts to
connect to my computer. You can find it on the Internet at
www.zonealarm.com.
