"Christians And The Internet" newsletter
CATI, Vol. 2, No. 18:  December 28, 2001.



The latest revision of this issue of "CATI" can be accessed
online at http://traver.org/cati/archives/cati63.htm.  The
Web page edition makes it especially easy to visit the links.

Here's something to make life simpler for CATI readers.  You
no longer have to remember http://traver.org/cati/ as the Web
address for the home page of the CATI Web site.  Yes, that
will still work, but this one's easier:


That's what I meant when I said that "CATI" is getting "ORG"-

The "CATI" part, as you well know, stands for "Christians And
The Internet."  The "ORG" part may be less familiar.  "COM"
refers to COMpanies or COMmercial endeavors, so "COM" is not
really appropriate for this free newsletter.  On the other
hand, "ORG" is used for non-profit ORGanizations and groups
whose orientation is toward service rather than making money.
So the domain name for CATI is cati.org, which should be easy
for you - and for your friends! - to remember.

Since CATI now has its own domain name, there is now also an
easier way to subscribe.  If someone wants to be put on the
CATI mailing list, all he or she has to do is to send an email
(including his or her name) to this email address:


(Likewise, sending a similar email to unsubscribe@cati.org is
a simple way to be removed from the list, although the old
ways to subscribe and to unsubscribe will also continue to

So remember:  "CATI" is getting "ORG"anized.  Be sure to tell
your friends about cati.org!

P.S.  For now, the new domain name works only for the CATI
home page, but you can get to anywhere on CATI's Web pages
beginning from that starting place.  CATI's files, however,
are still hosted at "traver.org," so you will still see that
reference when you visit various Web pages on the CATI Web
site, even if http://cati.org is where you begin.  (Also,
for now continue to use cati@traver.org as the email address
to use if you want to write to me.)


Jigsaw puzzles can be an enjoyable re-creation.  There is a
certain satisfaction that comes from bringing order out of
chaos.  But jigsaw puzzles ordinarily have disadvantages as
well as advantages.

For example, sometimes pieces get lost (and you may not
discover that until the puzzle is almost finished).  Or the
puzzle takes up the dining room table, making it difficult
to invite friends over for dinner.  Or the family cat or dog
may decide that puzzle pieces may look like fun for him or
her to play with (or maybe even eat?).

Well, I've written a jigsaw puzzle for the computer that you
may enjoy (people of all ages seem to enjoy jigsaw puzzles).
If your computer is running Windows 95 or later, the program
should work for you.  In some ways it's not the same as doing
a regular jigsaw puzzle (for example, with the Traver Jigsaw
program all the pieces are the same shape and size, that is,
rectangles, rather than having different shapes), but it can
be a nice way, say, to take a brief break from work so that
you're ready to go back refreshed.

Doing a jigsaw puzzle can be especially rewarding if the
picture being put together reminds us of the beauty of God's
world, the beauty of God's Word, or both (more about that in
a moment).  Well, I've written a jigsaw puzzle program for
you to enjoy, and you can download it from the Internet.

Perhaps the best way to describe the program is to go through
the menu selections on the top menu bar.  That menu bar reads
like this:

  File   Scale   Condition   Pieces   Mode   Status   Help

The _File_ menu provides these choices:  "Load Picture,"
"Save," "Restore," "Print," and "Exit."

For your puzzle picture, you can use any JPEG or GIF file
(the two most common graphics formats on the Internet) as
well as many other common graphics formats.  Here, for
example, is a place where you can find over a hundred JPG
pictures that will invite you to meditate upon significant
themes of Scripture (remember what I said earlier about
God's world and God's Word?):

Heart Gallery

To download a picture, right-click on it with your mouse.
Then choose "Save Picture As" (if you're using Microsoft
Internet Explorer) or "Save Image As" (if you're using
Netscape Navigator) or "Save Image" if you're using Opera
as your Web browser.  Be sure to save it in a location
where you'll be able to find it again.

Note:  Many pictures on the Web are copyrighted, which
means that - although they may be downloaded for your own
personal, private use - they should not be given to others
if the copyright owner has indicated that such should not
be done.  Note, for example, that the graphics in the "Heart
Gallery" are copyrighted and may be "reprinted and reused
for non-commercial purposes only if copyright credits are
appropriately displayed."

When you use "Load Picture" to load a picture, the pieces are
scrambled, just like a regular jigsaw puzzle.  Your job is to
put the pieces in their proper places.  If you're interrupted
before you are finished and must close down the program or
even the computer, you can "Save" the picture and the position
of the pieces to disk.  Then, at a later time, you will be
able to "Restore" things to what they were before, so that
you can pick up right where you left off.

That takes care of "Load Picture," "Save," and "Restore."
"Print" on the File menu prints out the picture (the way it
will look when it is put together) on your printer, and
"Exit" allows you to exit from the program.  So much for
the _File_ menu.  (Don't worry:  the other menus are much

The _Scale_ menu allows you two choices:  "Normal" (to display
the picture in its "Normal" size) or "Fit Screen" (to display
the picture in an optimal size for the screen, since for some
pictures the "normal" size of the picture may be larger than
the screen or much smaller than the screen).

The _Condition_ menu also gives you two choices:  "Scrambled"
(with the pieces mixed-up) or "Unscrambled" (with the pieces
put in their proper places).

The _Pieces_ menu allows you to decide how many pieces you
want in your puzzle.  Choices range from "2 x 2" (4 pieces,
suitable for small children) to "12 x 12" (144 pieces, which
can be challenging for adults, since all the pieces are all
the same shape and size).

The _Mode_ menu provides you with a choice of either of two
possible ways of moving the pieces:  "Drag Mode" or "Swap
Mode."  If you're using "Swap Mode," simply click on the
piece you want to move and then click on the place where
you want it moved.  The two pieces will swap places.  (When
you click on the piece, it becomes highlighted.  If you then
change your mind about what piece you want to move, simply
click on that same piece again, and the highlight will be

"Drag Mode" is a bit more complicated, but it's the mode
that most adults will prefer, because it's closer to the
way a jigsaw puzzle is normally put together.  When you
decide on the piece you want to move, press down the left
mouse button, but keep it pressed down.  Now when you
move the mouse, you'll find that the piece moves along
with it.  When the piece is where you want it to be, then
release the mouse button.  Computer people call this a
"drag and drop" operation, but it's not much different
from picking up a puzzle piece, trying it in various
locations, and putting it down where you think it goes.

The _Status_ menu lets you choose whether to "Show" or
not the status of the puzzle on the status line above
the puzzle.  (By status is meant simply the number of
pieces that are still not in their proper places.)

The _Help_ menu has two choices:  "About Traver Jigsaw"
(which tells you something about the program and its
author) and "How to Play" (which merely provides a brief
description of the difference between "Drag Mode" and
"Swap Mode").

It's simpler than it sounds.  By the way, so that I'm
not tempted to spend more time on it than I should, I
generally set the size of my puzzles to 4 x 4 or so, so
that I'm taking a restful, short work break (rather than
letting Traver Jigsaw become an excuse to avoid work).
I don't usually play computer games, but Traver Jigsaw
is an exception.

As I said, there's a certain satisfaction in bringing
order out of chaos.  This may sound far-fetched, but it
reminds me of the work God does when he puts together
the broken pieces of people's lives through the gospel.
The world itself in which we live is messed-up, but
that is not a puzzle that God cannot solve.  Rather,
from before the time the world was created, He had
made His plans that there would be in the future a new
heaven and a new earth, with everything where it should

Preachers tend to see a sermon in everything, including
even something as simple as putting a jigsaw puzzle
together.  Whether or not you are inclined to mix some
theologizing with your jigsaw puzzle activity, I hope
you will enjoy Traver Jigsaw.  You can download it from
this location:


After you download the file, you will need to unzip it.
(If you need help on that, let me know.)  After you have
unzipped it, then run setup.exe to install the program,
Traver Jigsaw, which is a gift from me to you.  When you
install the program, it is probably best to stay with the
suggested defaults.  (If you want to remove Traver Jigsaw
later, simply use Start -> Settings -> Control Panel ->
Add/Remove Programs.)  Questions?  Just ask!



Some CATI readers may have decided to sign up with a family-
friendly ISP (Internet Service Provider).  If you are one of
them, you may be able to help me.  I'm hoping to do another
article in the near future on family-friendly ISPs, and I
would love to get an email from you, telling me of your own
experiences (if any) in that area.  What ISP are you using?
Are you happy or not happy with the result?  Why?  Send an
email message to me at cati@traver.org on this topic (or on
any other subject related to the Internet, if you're willing
to share your thoughts with me), and I'll be very grateful.

Thank you for your participation in the CATI project!


Within the past two weeks, I've received quite a few warnings
about the SULFNBK.EXE virus.  Six months ago in CATI (June 15,
2001) I had warned readers about the SULFNBK.EXE virus warning


Well, there are now new versions of the warnings circulating,
but it's still a hoax.  What you need to know is that you are
no more likely (and no less likely) to get infected through
SULFNBK.EXE than you are from any other executable file (and
that includes files ending with extensions .exe, .com, .bat,
.pif, .vbs, .scr, and .doc).  But it provides an opportunity
for me to remind people NOT to open an email attachment until
you have checked it out adequately first (preferably scanning
it with a good anti-virus program), even if the attachment
comes from the email address of a good friend.  On the
Internet it is especially important for Christians to be
"wise as serpents, innocent as doves."

Bob Rankin in his Internet TOURBUS newsletter, December 21,
2001, writes of "The Return of the SULFNBK.EXE Virus Hoax":

"Do you remember the 'honor system' virus?  It was a joke
that was passed around the Internet last summer: 'This virus
works on the honor system. Please forward this message to
everyone you know, then delete all the files on your hard
disk. Thank you for your cooperation.'  Well, a few months
ago [actually, at least six months ago] a nefarious netizen
[i.e., citizen of the Internet] took the 'honor system' virus
joke, rewrote it, and created an equally fake virus warning
that many newbies have taken seriously.  The new warning asks
you to scan your hard drive for a file named SULFNBK.EXE and,
if you find it, to delete it from your system. <SIGH>"

It's a hoax, as CATI reported six months ago and as Bob Rankin
explains in his recent newsletter:

"What the virus warning fails to tell you is that SULFNBK.EXE
is *NOT* a virus, it is a Windows utility used to restore
long file names in the case of a catastrophic crash.  DON'T

Rankin uses the SULFNBK.EXE hoax to teach an important lesson:

"Long story short: if someone sends you an email that asks you
to do *ANYTHING* -- invest money, sign an online petition,
warn your friends about a new virus threat, delete files from
your Windows system folder, forward information to everyone
you know, yadda yadda yadda -- take two seconds to verify the
contents of the email before you do ANYTHING!  It is so simple
to do, and it keeps you from making a fool of yourself in
front of the entire planet."

And he proves his point with SULFNBK.EXE:

"For example, a simple search at http://www.google.com/ for
'SULFNBK.EXE' results in 13,800 hits, and EVERY ONE of the
first 10 hits shows you that that the SULFNBK.EXE virus
warning is a hoax (and the sixth hit is actually a page at
my Web site, NetSquirrel.com, telling you how to restore
SULFNBK.EXE in case you were foolish enough to delete it).
Two seconds of work and you keep from damaging your system."

By the way, the Internet TOURBUS, written by Bob Rankin and
Patrick Crispen, is a worthwhile free newsletter about "search
engines, cool sites, free stuff, viruses, hoaxes, urban
legends, internet tools and tips, cookies, and more!"  Here's
the home page, if you want to check it out further:

Internet TOURBUS

Actually, the SULFNBK.EXE situation is a bit more complicated
than the preceding suggests, so let me clarify the situation
in a bit more detail.  (Skip to the last paragraph if you want
to read the bottom line concerning virus threats in general
and the supposed SULFNBK.EXE virus threat in particular.

_Any_ e-mail file attachment (even from someone you know) is
a potential virus and ought to be checked with a virus scanner
before it is opened.  A file attachment (especially one that
is a virus-infected file from a friend's computer) may have
_any_ name.  It is not likely to have the name SULFNBK.EXE,
but if you do get a file attachment with SULFNBK.EXE as the
filename, you should be very suspicious (because why should
anyone be sending you that file unless perhaps you asked him
or her to send a replacement for the file you mistakenly may
have deleted?).

Here's is what F-Secure (the makers of F-Secure Anti-Virus)
state about the SULFNBK.EXE warning:

"In April-May 2001 there appeared a hoax message concerning
a new virus that was reportedly discovered in ... SULFNBK.EXE.
We checked several versions of this utility from Windows
installations and found no infection in it. However, some
e-mail worms (for example, Magistr) might  sometimes send an
infected SULFNBK.EXE in an e-mail attachment.  Bottom line:
if you get SULFNBK.EXE in an e-mail attachment, it's probably
a virus. If you find it from your Windows directory, it's
probably not....  If you receive these hoax messages, please
ignore them."

Note well:  It is extremely unlikely that you will get a
SULFNBK.EXE email virus (and, as far as I know, there is
no evidence of anyone's having gotten such a virus at this
point).  File attachment viruses are being sent around, but
with a limitless number of possible filenames.  Thus (as far
as I know), all makers of anti-virus software advise that
SULFNBK.EXE warnings be ignored and NOT passed around.

Here are some more examples:

Symantec (makers of Norton Antivirus):
"Symantec Security Response encourages you to ignore any
messages regarding this hoax. It is harmless and is intended
only to cause unwarranted concern."

Note that this Norton Web page was "Last Updated December 19,
2001," so it's Norton's current statement on the situation!

McAfee (makers of McAfee Anti-virus):
"This email message is just a HOAX. Although the SULFNBK.EXE
file may become infected by a number of valid viruses (most
commonly W32/Magistr@MM), the details of this HOAX message
are not based on actual events.  We are advising users who
receive the email to delete the message and DO NOT pass it on
as this is how an email HOAX propagates."

Norton and McAfee are the leading providers of anti-virus
software.  Here are some comments from another anti-virus
software provider:

Sophos (makers of Sophos Anti-Virus):
"Sophos advises users to treat the warning with skepticism.
Many computers do have a legitimate uninfected version of
SULFNBK.EXE on them....  The confusion is compounded,
however, by the W32/Magistr-A virus which is capable of
emailing infected copies of SULFNBK.EXE to innocent users.
This is probably how the scare started.  Sophos offers users
confused by the hoax warning and the virus, the following
advice:  If you receive an unsolicited executable file in
your email (such as SULFNBK.EXE), simply delete the email.
You should never launch or open unsolicited executable code
on your computer. Existence of a file called SULFNBK.EXE
on your hard drive is not evidence in itself of a virus
infection. The best way to check for a virus infection is
with anti-virus software. Run a quality anti-virus product
and keep it updated to protect against the latest threats.
Do not pass on virus warnings to all of your friends.
Instead, check the facts at an anti-virus website...."

Bottom line:  DO NOT be concerned about warnings of possible
SULFNBK.EXE virus threats, because no such threat has been
documented at this point. And DO NOT pass around warnings
about a SULFNBK.EXE virus threat.  DO NOT, however, open
email file attachments (whatever the filename may be and
regardless of the sender) unless they have been checked with
an up-to-date good virus scanner (such as Norton or McAfee).
And DO protect your system with a good anti-virus program
(again, such as Norton or McAfee).


Like to know what this is?  This is the sixty-third issue of
a free newsletter devoted to "Christians And The Internet"
("CATI," pronounced "Katy," but spelled with a "C" and an "I"
for "Christians" and the "Internet").
