Personal Information
Who knows what? About you, I mean, and how much does it matter to
you? “It matters a lot! My information is private! My private
life is my business and not anybody else’s.” This would be a fairly
typical immediate response from the “person on the street”, but even so, it is
nowhere near the reality, nor even their true opinion, when you get right down
to it.

life is my business and not anybody else’s.” This would be a fairly
typical immediate response from the “person on the street”, but even so, it is
nowhere near the reality, nor even their true opinion, when you get right down
to it.
I had the great pleasure this morning of listening to Mr. Tom Ridge deliver
a keynote speech at the Information Security conference, Infosec 2006. Mr.
Ridge, you may recall, is the former Governor of the State of Pennsylvania who
was called upon by President Bush after 9/11 to form the US Department of
Homeland Security. He is now retired from public service. When you
think about how broad a problem “Information Security” is you can see why he is
such an appropriate speaker. He delivered a speech that was thoughtful,
informed, entertaining and provocative, and included ideas that I’d like to
share with you today.

informed, entertaining and provocative, and included ideas that I’d like to

Addressing my original question, consider this: you buy a few books,
now and then, from your favorite bookseller, and have signed up for their
members club so that you can receive the extra 10% discount on everything you
buy. After a while, you receive a letter in the mail that reads something
like: “Dear Valuable Customer,” (actually, some may even include your real
name!) “We have noted your interest in biographies, especially those
written by Mr. A. Jones, and would like to point out to you that Mr. Jones’
latest biography, that of Mr. B. Smith, is now available in our stores. In
appreciation of your loyalty, we would like to offer you the enclosed 15%
discount coupon against the purchase of this book. …… etc. etc.”
How do you feel about receiving this letter? Does it matter to you what
the quantity and type of information it is that they have to gather to be able
to do this? Does it matter to you with whom they share this
information? (Did you actually read the disclosures when you signed that
original membership form?)

Now consider this: you have used your local library for several
years. Your library, or course, is a part of your local government, which
in turn, of course, cooperates with the next levels of government, however they
may be structured where you love. You receive a letter in the mail from
the library reading something like: “We have noted your interest in (subject
matter) and would like to inform you that we have recently received stock of
(book[s]) by (author[s]) which may be of interest to you.
Please…… etc. etc.” Now, how do you feel about that one?

Does it matter to you how much information is gathered about you by
government agencies, who, if you live in a democracy, ultimately are responsible
to you, the voters, versus how much is gathered by anonymous corporate
executives and their organizations? To most people there is a
difference. The question is, should there be, and if so, is that
difference correctly oriented?

As I said, Mr. Ridge’s speech was provocative!
Thanks for reading!

Q. I’m trying to get some
JavaScript running. I’m able to parse two vars to a function, the third one will
not work.
This is the function:
<.SCRIPT
LANGUAGE=”javascript”>
function nieuw(a,b) {window.open (a, b,
config=’height=600,width=200,toolbar=no, menubar=no, scrollbars=no,
resizable=no,location=no, directories=no,
status=no’)}
<./SCRIPT>
It’s called by:
<.a href=#
onclick=”nieuw (‘bijeenkomsten.html’,
‘newwindow’)”>Bijeenkomsten<./a>
My goal is to have the screensize
set by the calling function, so far i’m unable to do that. I tried by replacing
the height and width values by var’s, tried to put the height and width into the
caller, nothing works. Is it possible to do that or not, if yes how?
A. Actually, you can do it without calling a function. Try this for your
code:
<.a href=”javascript:location=’bijeenkomsten.html’;
window.open(‘bijeenkomsten.html’,’Bijeenkomsten’,
‘height=600,width=200,top=10,left=10,toolbar=no, menubar=no, scrollbars=no,
resizable=no,location=no, directories=no,
status=no’)”>Bijeenkomsten<./a>
Notice that I added two more
attributes, top and left. You can determine where to position the window as
well. If you need to use the function, your call is good, except for one
possible item. Is newwindow the title of the window? If not, replace newwindow
with the title (could it be Bijeenkomsten?)
As for the function itself,
remove config=.
Here it is:
<.SCRIPT
LANGUAGE=”javascript”>
function nieuw(a,b) {window.open (a, b,
‘height=600,width=200,toolbar=no, menubar=no, scrollbars=no,
resizable=no,location=no, directories=no, status=no’)}
<./SCRIPT>
code:
<.a href=”javascript:location=’bijeenkomsten.html’;
window.open(‘bijeenkomsten.html’,’Bijeenkomsten’,
‘height=600,width=200,top=10,left=10,toolbar=no, menubar=no, scrollbars=no,
resizable=no,location=no, directories=no,
status=no’)”>Bijeenkomsten<./a>

Q. Where is the tutorial on
mouse over for “click here”?
A. You should be able to find one in the JavaScript Primers on the HTML
Goodies site. Here is a link to the Table of Contents: https://www.htmlgoodies.com/primers/jsp/index.php

Q. When you open a new window
is it possible to close the original window? When I run this code I just
get an error message after the new window opens.
window.open(“page.html”,
“whatever”, config=”height=500,width=500″) self.close;
I’ve tried replacing
self.close with main.close and window.close but I always get errors.
main.close only works for closing new windows.
A. The reason you are getting the erros is that you have the wrong syntax
for your window close. The correct syntax should
be:
self.close()
or:
window.close()
to close the original
window. The other problem that you will have is that when you use
JavaScript to close the original or main window an alert will popup asking you
wether you want to close it or not. This is a security feature that keeps
someone from closing the window without the viewer’s permission.
JavaScript is not allowed to close the main window.

Q. I am trying to open a new
window using Javascript and I have suceeded in doing so. But I have encountered
a problem: the window opens with half on the screen and half the window off.
Basically if a user wants to see the other half of the new window, they must
drag it into a new position. Do you have any sugestions on how to get the window
to open on a specified place on the x-axis and the y-axis of the user
monitor?

A. One method is to use the top and left properties. Here is an
example:
function OpenWin()
{ PopMen=window.open
(“poplink.html”,”popwin”,config=”width=175,height=225,location=no,status=no,directories=no,toolbar=no,scrollbars=no,menubar=no,resizable=no,top=0,left=0″);
}

function OpenWin()
{ PopMen=window.open
(“poplink.html”,”popwin”,config=”width=175,height=225,location=no,status=no,directories=no,toolbar=no,scrollbars=no,menubar=no,resizable=no,top=0,left=0″);

Q. I was using the tutorial in my HTML goodies book on JavaScript. I
used the code in the book, but i altered it for my own use. I cant get it
to work, and I dont know why. It seems like a perfectly sound code to me,
but when I try and run it, I get an Object Expected error for the
<.onLoad> command. (code was attached)

A. In your script, you have “funtion dateinbar()”, just change it to
“function dateinbar()” and the problem should go away.
[This is such a common
type of error – no matter what your level of experience, have someone else look
at your code. Often a fresh pair of eyes sees something so obvious that we
ourselves keep missing it!]
