A Noteworthy LaptopGoodies To Go readers, being into web development and all thing Internet,
are frequently techno-road warriors.
This being so, I thought I
’
d share
with you my experiences and the end result of my attempts to replace my
trusty laptop.
It
’
s not that it no longer functions, or that there is
something I cannot live without that it doesn
’
t do; it
’
s just that there
’
s
so much cool stuff out there that I had to get my fingers on some of it.
Actually, there is something it doesn
’
t do that I am no longer willing to
live without, and that is to respond to my touch on the screen.
Looking at my current machine and sizing up the features that must be
present in the replacement, I determine that, apart from the standard stuff,
the highlight is my wireless broadband access provided by my carrier,
Verizon Wireless, via an adapter card in the PCMCIA slot.
I
’
ve written
about this before, as some of you may remember.
We
’
re not talking WiFi;
it
’
s a high speed (700-800kbps is typical) digital data service provided by
the cell-phone company and providing national (US) coverage.
CAN NOT do
without that!
The touch feature is typical of tablet PCs, and there are other aspects of
tablet PCs that I like.
I cannot, however be without my keyboard
–
I do,
after all, spend a good deal of time writing!
What I need therefore, is a
computer that can be a laptop part of the time, and a tablet the rest of the
time.
Machines like this are called convertibles or, and this is the name I
like best, hybrids.
I started the hunt.
I found quite a wide price scale but was astonished to
find that no matter where I looked in the price line, hybrid after hybrid
lacked the one feature of my notebook that I absolutely had to have
—
they
had no PCMCIA slot!
I cannot understand why, when the entire purpose of the
hybrid is to provide the best of both worlds, such a crucial feature is left
out.
Despondent and about to call the world a rotten place, I decided to give
Google one last chance.
I did a search that included both of the words,
hybrid and PCMCIA.
Eureka!
(Actually, Googlereka!)
The search results
included a page in Gateway Computer
’
s website.
Off we go, and
…
.
in about
ten days time I will be the recipient of a gateway hybrid with a sparkling
PCMCIA slot and a nice fourteen inch screen.
A little while after that,
I
’
ll let you know whether or not it meets my expectations
—
that is, is the
world wide world still a fine and rosy place in which to live and work, or
will I have encountered a techno-hades.
I
’
ll keep you posted
–
just watch this space!
Thanks for reading!

Q & A Goodies***********************************
Questions are taken from submissions to our Community
Mentors. You can ask a Mentor a question by going to
Is there a way to use a background image without it repeating? I
’
d like
the bgimg to simply enlarge itself to encompass each visitor
’
s window,
instead of doing the tile effect.
A.You are not going to be able to get the image to enlarge itself for every
resolution. In fact the site you sent has the image repeating. I even looked
at it on various resolutions and it repeated in all of them. That being
said, you can use some CSS
–
Cascading Style Sheet
–
to get an image to
only show once as a background.
Here is the code you should use:
<
style type=
"
text/css
"
>
<
!
–
body {background-image: url(images/your_image_name.gif);
background-repeat: no-repeat;}
–
>
<
/style
>
Make sure you change the path and image name to suit your situation.
This question most specifically refers to Javascript primer #27 on
.
I was
just wondering if there
’
s any way to make a link out of each of the pictures
of the slide show, or better yet, open a new window from each with
javascript? (by clicking on the picture of course.)
I was also wondering if
there
’
s a way to make a back one picture button without losing the forward
one picture button. Here
’
s the code..

I am trying to load a new page into a frame with:
top.frame1.document.location=
"
root/subfolder1/subfolder2/filename.htm
"
;
and for some reason it works only if I put an alert before the statement.
A.Try:
top.frame1.location=
"
root/subfolder1/subfolder2/filename.htm
"
;
You can also use:
parent.frame1.location=
"
root/subfolder1/subfolder2/filename.htm
"
;
Either one should work.
Q.I am running a site and many of my articles are being stolen by copy+paste.
Is there a way that when you right click an alert box comes up
and not the regular box with copy and paste on it?
A.First I have to tell you that there is no fool proof way to keep someone
from taking your articles from your web pages.
Every time your web page is
displayed on someones PC the page is download to their cache so that it can
be displayed much more quickly.
The same goes for any images that are
displayed on the page.
Having said that here is a link to a site that has
some scripts that can help:
[
It
’
s not a free solution, but you can also provide some protection by
creating password protected PDFs with Adobe Acrobat and including your
copyright information on the pages of your articles.

1606Guy Fawkes Died
On this day in 1606, moments before he was to be executed for treason in
London, England, Guy Fawkes leapt to his death.
The date was November 5th,
1605.
The British Parliament was due to start a General Assembly the next
day.
Justice of the Peace Sir Thomas Knyvet found Guy Fawkes in the cellar
of the Parliament Building in Westminster, along with two tons of
gunpowder.
He was detained.
The investigation that followed revealed,
largely by Fawkes explanations, the
"
Gunpowder Plot
"
as a conspiracy by the
English Catholics to annihilate the entire Protestant parliament, along with
the Protestant King, James I, who would have been in attendance.
The day,
November 5th, is celebrated across England with bonfires and fireworks.
An
effigy of Guy Fawkes is traditionally set atop the bonfire.
The celebration
remembers the discovery and foiling of the Plot, although there are those
who say it celebrates the attempt!
