THE WEB IS DYNAMIC
If you want a permanent copy of some
information that’s stored on the web, you have to save it locally because the
content can change any time, even while you’re viewing the page.

If you’re browsing that information, you
don’t have to install a new version of the help system, buy another book, or
call technical support to get updated information., just launch your browser
and a check out what’s there .
If you’re publishing on the web, you can
make sure that your information is up-to-date all the time. You don’t have to
spend a lot of time re-releasing updated
documents. There’s no cost of materials. You don’t have to get bids on
numbers of copies or quality of output. Color is free. And you won’t get calls
from hapless customers who have a version of the book that was obsolete four
years ago.
Consider a book published and distributed
entirely online, such as thinking in java by Bruce Eckel
(which you can find at www.mindview.net/books/TIJ/) . he can correct any mistakes in the book and
simply upload the revised text to t\his website, making it instantly available
to his readers. He can document new features of java and include them in the
latest version of the book on his site. The website for the book appears in
FIGURE 1.1.
NOTE
The pictures throughout this book usually
are taken from firefox funning on Mac
OS X . the only reason for this use is
that I’m writing this book on an apple power book. If you’re using a different
operating system, don’t feel left out. As I noted earlier, the glory of the web
is that you see the same l\information regardless of the platform you’re
s\using. So, ignore the buttons and window borders and focus on what’s inside
the window.

java.
For some sites, the capability to update
the site on the fly, a any moment, is precisely why the site exists. Figure 1.2
shows the home page for Yahoo! News, an
online news site that’s updated 24 hours a day to reflect up-to-the minute news
as it happens. Because the site is up and available all the time, it has an
immediacy that neither hard-copy newspapers nor most television news programs
can match . visit Yahoo! News at http:// news .yahoo.com.
