Ask Ed Cyber
Dear Ed,
I am a teacher at a public school. I recently purchased a new computer for
use at home. It came installed with Windows 98. Windows 2000 is supposed
to be released on the 17th. Should I upgrade?
'98 Education User
Dear Mr. or Ms. User,
You ask a very good question. Let me summarize the following by saying
that I don't think you need to upgrade to 2000. Why?
Windows 2000 will be a good operating system for business users, providing
the stability and security they need while working in a business
environment. While your school may need to seriously consider upgrading,
it is not such a must for the individual user, especially considering the
cost.
Actually, 2000 is more of an upgrade for Windows NT than it is for 95/98
but the upgrade will work fine with Windows 98. It provides greater
stability (in other words, it doesn't crash as frequently) than Windows
95 / 98 but is just different enough in the way that it works that I
recommend waiting a while.
Don't get me wrong. Windows 2000 is definitely the operating system of
the future in its support for new technologies like USB, AGP and IEEE 1394
(FireWire). I won't discuss these technologies here, but over the next
few years these are the technologies that will be used to connect things
to your computer. However, the gains you make aren't likely to make the
cost of upgrading worth it. At the very least, I recommend waiting until
the dust settles on the new release to make sure there aren't major bugs
that need to be ironed out.
When the dust settles and if this new OS is all that it is touted to be,
you might want to consider this upgrade again in a year or so. By then,
depending of course on what happens in the courts, it's likely that the
cost of upgrading will have come down considerably.
Web Site Review
Super Bowl Commercials
http://www.yahoo.com/promotions/superspots/
Did you miss any of the superbowl commercials? Some
were good and some were not but they are all available for viewing online
at yahoo.
Whether you think advertising has become too prevalent or not (see this
month's Edunotes for Educators for an article on Advertising in schools)
you have to admit there were some interesting commercials here.
Tables without Edges
Sounds kind of strange, doesn't it? Only we're
not talking about the kitchen table. Tables are very useful for formatting
web pages.
When you create a file in a word processing program like MS Word or Corel
WordPerfect, you have complete control over the layout and can be certain
that the intended reader will see exactly what you see.
When you create an html file, on the other hand, there is no such
guarantee. The file you create may look great on your PC with your 1024 X
768 monitor settings but look absolutely terrible on a computer where the
settings are 800 X 600.
Tables can solve a lot of the formatting problems. When you create a page
in html, whether you press the space bar once or 20 times, you still only
get one space. Tabs are useless. Rather than get into why this is so, let's
focus on what we can do to get around this.
If you put text in a table, it will let you create the same look as having
nicely tabbed pages. For example, if you had a price list with tabs it
might look like this:
| Motley Fool |
$10.40 |
| Wall Street Journal |
$12.76 |
| Internet Bubble |
$18.90 |
But in HTML it would look like this
Motley Fool$10.40
Wall Street Journal$12.76
Internet Bubble$18.90
Create a table in HTML and it goes back to looking
like this
| Motley Fool |
$10.40 |
| Wall Street Journal |
$12.76 |
| Internet Bubble |
$18.90 |
The cool thing about using a table is that in HTML
you can set the border to "0" and it would like just like the
first example above.
You can also use the tables to control how wide your pages are. As we
mentioned above, there is no way to control what screen dimensions the
person viewing your page has, but you can use a table to make it look
almost the same for every viewer.
When you create a table, you set the width by either a percentage or by
the number of pixels. A table set to a width of 100% would fill the whole
browser from left to right. A table set to 600 pixels, on the other hand,
would not fill up a whole browser if the screen dimensions are 1024 X 768.
So if you're starting to make your own web pages, use tables to control
the way the pages look and provide a consistent viewing experience for
those viewing your pages. |
DSL is Here
The promise of high speed Internet access has
arrived in a big way. DSL (see EduWords for definitions), along with
cable, is transforming the way we access the Internet and even the way we
use the Internet.
One of the things that makes DSL so palatable to the general public is
that it doesn't involve running a completely new infrastructure. Since
it uses the plain old telephone service (POTS) that already exists, the
companies that sell DSL don't have to start all over and thus they can
charge consumers less.
The bandwidth of a 56K modem doesn't even begin to compare with the
bandwidth of DSL. Running in optimal conditions, a 56K modem can download
data from the Internet at 52 Kbps (52,000 bits per second) while an ADSL
line ranges from 1.5 to 9 Mbps (1,500,000 to 9,000,000 bits per second).
If you're browsing for fun, this might not be such a big deal although
graphics will load in your browser much faster. The business user will
find a big benefit in downloading files or programs much faster. Following
the old adage that time is money, you'll save big with DSL.
Perhaps the most exciting thing about DSL is the way it can and is
changing the way we use the Internet. If you have enough bandwidth to
quickly download programs, you can download the program you need, be it a
spreadsheet program, word processing program, or calendaring program,
without having to buy or license an expensive suite of programs. If you
don't think this has Microsoft worried, you're still living in the
20th century.
DSL is available in large parts of the Denver Metro area. Companies like
Covad, Jato, and Concentric are aggressively marketing their DSL services
to compete with US West's megabit service. Visit their respective web
sites to learn more.

It had to be too good to last. The incredible inter-
networked world we have created and dubbed the Internet is vulnerable.
The last week or so, we have seen large web sites get attacked and
rendered inaccessible for hours. The attackers haven't broken into the
web sites, instead they have simply bombarded them so that no one else can
get through in what is called a "Distributed Denial of Service."
How does it work? Since the culprits have yet to be tracked down, we can't
say for sure exactly but it works something like this A Hacker hacks into
a computer on a network with low security and high speed Internet access.
He or she then plants a program and exits. Later, at the appointed time,
the hacker activates the program, which then begins bombarding the target
site. Several of these programs distributed around can be quite effective
in bringing down or tying up a web site.
So what does it all mean? Unfortunately it probably means that a lot of
lawyers will make a lot of money as the companies / schools that own the
computers that were hacked into are revealed and the companies being
attacked sue.
It also means that if you have a computer network, you should take
security seriously. Had everyone implemented appropriate security, the
attack wouldn't have been possible, as the computers wouldn't have
been hacked into in the first place.
For those in the IT business, it's good news in the form of increased
job security but for businesses large and small, it will mean an increase
in the money and personnel resources they set aside to ensure their
network is safe.
