Migrate to New Technology
Lesson 1: Changing Technology
Read the following newspaper articles:
o IBM Unveils its Runner in the PC Stakes (SMH 10/2/1983)
o The PC Turns 25 (SMH 11/8/2006)
Discuss the Changes in computers since 1983.
Lesson 2: Selecting New Technology
How do YOU cope with new technology?
To learn about new technologies, you will have to refer to trade magazines,
manuals and web sites relevant to the particular technology.
The more software packages you have learned, the easier it is to learn the next
one.
The more different networks you have worked with, the easier it is to learn about
the next new one.
The greater the range of hardware you have worked on, installed and maintained,
the easier it is to work with a new hardware product.
Why is this?
Many features of technology are similar, no matter how old or new the
technology.
For example,
Word processing packages contain many similar features
Programming languages all contain some basic types of statements
Networks conform to a limited range of standards.
So, when getting started with some new technology, "the expert" looks for the
features that are the same or similar.
Once you have identified and used features of the new technology that are
familiar, you can begin to investigate the less familiar features of new technology.
To do this you use skills in reading and understanding product documentation
(manuals, on line help, web sites, magazine articles) as well as experimenting
with the product.
Sometimes you might attend training sessions or user group meetings.
Learning a new product is not always easy, especially if you have to teach
yourself.
Often the most effective way is to find a task or project that needs to be done
using the new technology, then work on the new task or project, learning features
of the new technology as you go.
From an organization's point of view, new technology is only useful and
worthwhile if it can be:
Put to use quickly
Used for tasks that couldn't be done before
Used to complete tasks more efficiently.
New technology is not useful just because it is interesting or fun. But new features
of technology can sometimes provide new ways to solve organizational problems.
The support person's role is to:
Learn enough about the new technology to install or set it up
Ensure that information such as documentation about the technology is
available
Learn how to use the new technology
Show other people how to use the new technology
Use the new technology to solve organizational problems.
WRITTEN ACTIVITY 1
Migrate To New Technology - 2
1. Using the Internet investigate other software that is similar to Microsoft
Office. For example, Word Perfect is a word processor like Microsoft
Word. Investigate the differences and similarities between these software
packages.
2. Mozilla Firefox is a web browser similar to Internet Explorer. Compare the
two products. How are they similar? How are they different? Which do
you prefer and why?
101 things that the Mozilla browser can do that IE cannot:
The following lists 101 things that one can do with the Mozilla browser
component (version 1.2) that one cannot do with IE (version 6.0). I used the
Windows version of IE 6.0; the list will vary slightly for the Mac version:
1. Tabbed browsing
Lets you display more than one site in a window using multiple tabs.
You can open a new tab by selecting Navigator Tab from the New
submenu of the File menu (or press Ctrl+T). You can also open a link
in a new tab by using the right-click menu. You will find configuration
options in the Tabbed Browsing preferences panel.
Note that CrazyBrowser is a different product than IE.
2. Popup blocking
Block all those popup ads. To disable popup windows, select
Advanced and then Scripts & Plugins from the Preferences window.
Then uncheck the box that reads "Open unrequested windows".
3. Prevent scripts from doing various things
You can prevent scripts from moving windows, closing them, changing
the status bar and setting cookies. To change these settings, select
Advanced and then Scripts & Plugins from the Preferences window.
Then uncheck the desired boxes.
4. Site Navigation toolbar
Displays content from the tags provided by a document, allowing
one to navigate to various parts of a site.
5. Sidebar
The sidebar provides a number of tabs by default, and others can be
added by the user.
6. Can add custom panels to sidebar
Custom sidebars can be implemented in HTML or XUL and can be
installed from a remote site without much hassle. Sites can add
sidebars using the window.sidebar.addPanel() function.
Migrate To New Technology - 3
7. More control over text zooming
Can zoom text to any size. IE only supports five sizes and has no
keyboard shortcut that I could determine. For sites that use fairly small
fonts, having more larger sizes in necessary for those without perfect
vision.
Note that using the mouse isn't a keyboard shortcut.
8. Can zoom any text, even that with fixed pixel sizes
Can zoom text no matter what units were specified, an often cited issue
with IE.
9. Can select from multiple stylesheets provided by page
When a page provides multiple (or alternate) stylesheets, one can
select between them by choosing from the Use Style sub-menu in the
View menu.
10. Page info dialog
Provides additional information about encoding, MIME type, referrer
and meta tags. Some of this information is also available in IE's
properties dialog although it isn't as detailed and the window isn't
resizable.
11. Detailed form/link/media info dialog
The page info dialog provides tabs which have lists of the form
elements, links, images and other media in a page. You can even
preview images and save them from this window.
12. Save plugins
Mozilla saves plugins when saving a Web page as complete. You can
also save them from the Page Info window.
13. Themes
Provides two themes by default (Classic and Modern), but others may
be installed.
There is a theming system that is part of Windows XP, however this isn't supported
by Microsoft. It also isn't part of any other version of Windows. Mozilla's themes work
on all versions of Windows and on all platforms; you can change your theme by
selecting Apply Theme from the View menu.
14. Bookmark window displays more detail
Displays more information about the bookmark in the bookmark
window. IE's favorites dialog is a bit awkward and is modal, which
means you can't interact with the browser window while it is open. You
also cannot add bookmarks from the window.
15. Bookmark keywords
Migrate To New Technology - 4
Keywords to look up bookmarks quickly. Keywords have the advantage
that the part entered after the keyword is filled in where '%s' appears in
the bookmarks's URL.
16. Bookmarks can be checked at a certain schedule
One can set bookmarks to be checked at various schedules and notify
when the content has changed. At least, in theory. IE has something
like this, which is intended for synchronizing content for offline viewing.
It can only check once per day, and provides no notification that the
page has changed other than changing the icon or sending an email.
Mozilla can check updates on certain days only and at any interval.
17. Cookie Manager
The cookie manager lets you view the cookies that have been set, their
values and their expiry times.
Some people have mentioned that one can view Cookies by pressing a View Files
button in the Options, but that just provides a list of all cached files. While the list
does include cookies, hidden amongst the other files, it isn't tailored to cookies (it is
just a generic file listing), so one cannot really view the data or expiry times easily.
18. Can delete cookies individually
The cookie manager lets you delete individual cookies without having
to search around your file system. In IE's file view, it's tricky to
distinguish cookies from similar domains, and all cookies from the
same domain are stored in the same file.
19. Block images from third party sites
One can block images that come from a third party domain. This
means that you can block images found on a page that come from a
site other than that of the page. To set this in Mozilla, open Privacy &
Security from the Preferences Window, and then select the Images
panel. Choose "Accept images that come from the originating server
only".
20. Can block images from certain sites
Images can be blocked from particular domains, such as those that
commonly display ads. You can disable an image from a site by right-
clicking on an image, and then selecting "Block images from this
Server". You can change the list of blocked images from the Image
Manager, opened from the Tools menu.
21. Download Manager
The download manager provides a tabular view of all of the files that
you have ever downloaded, allowing you to open them without having
to search around on your file system. It provides progress indicators in
the window as items download.
Migrate To New Technology - 5
On the topic of downloading files, IE does not begin to download a file
until you have selected where to save it to, while Mozilla begins as
soon as the link is clicked, downloading in the background while you
are selecting a place to save it.
22. Can pause downloads
In Mozilla, one cause pause downloads. Some people may find this
useful during long downloads.
23. View Source
View the syntax coloured source of a page, without having to view it in
Notepad.
Some people have mentioned that one can edit the page using Notepad (or at least a
copy of it). True, but that's what Edit in the File menu is for. Some people like a
simple source viewer for viewing content.
24. JavaScript Console
The console displays a log of errors that you can easily scroll through,
or ignore if so desired.
25. JavaScript Console displays script warnings
The console separates warnings and errors. The warnings allow you to
see obsolete script usage and so forth.
26. JavaScript Debugger
This is a utility for debugging JavaScript.
27. DOM Inspector
View the structure of a document using a nifty tree view. Also lets you
view script properties and style applied to each element. You can open
it from the Tools -> Web Development men.
28. DOM Inspector image capture
The DOM Inspector has a tool to capture an image of part of a page,
although it doesn't seem to work all too well.
29. Select text and perform search
Select some text, bring up the context menu, and choose 'Search' to
search for the selected text.
30. Can select custom search engine
You can select any search engine you wish, not just one that has been
chosen for you.
31. Can display search results in sidebar
Migrate To New Technology - 6
When one does a search via a search engine, results are automatically
interpreted and displayed in the sidebar. You can then view pages
without hiding the search results.
32. Supports any Sherlock search plugin
Supports the Macintosh Sherlock search format, so any search engine
that supports it can be used.
33. Can manage saved passwords
Lets you view and delete stored login and passwords. Choose the
Password Manager from the Tools menu.
34. Can fill-in complete forms automatically
Stores complete forms which can be later be filled in automatically.
This is useful if you want to register for something 600 times. To fill in a
form, choose Fill In Form from the Edit menu.
35. Master password encrypts info
A single master password can be used to protect all of your other
passwords.
36. Can disable tooltips
Not very exciting, but useful if someone thinks they get in the way.
37. Caret Browsing
Press F7 and a cursor appears on the page. This can be used to
navigate a page and select text using only the keyboard.
Some people thought this was this the same as setting contenteditable="true" on an
element. While that does show a cursor in IE, it actually allows the content to be
edited, and disables all links and mouse events with-in the content. Caret browsing in
Mozilla is designed to allow one to browse, navigate links and select text using only
the keyboard.
38. Type Ahead Find
Press a few keys to search for links with that text. More information
39. View Selection Source
Select some text, bring up the context menu, and choose 'View
Selection Source' to view the source just for the selected content. This
can also be used to view the generated source after an XSLT
transformation.
40. Properties dialog lets you see info about various tags
Right click on certain links and images and so on, and view info about
them, such as language and whether links will open in a new window.
The window can also be resized.
Migrate To New Technology - 7
41. View scripts and stylesheets directly
Mozilla can display scripts and stylesheets directly as plain text without
a separate application which is useful if you just want a quick peek at
something.
42. More font options
One has more control over the fonts used, including customizing the
various CSS fonts. To change this, select Appearance and then Fonts
from the Preferences window.
43. Can set minimum font sizes
Can set the minimum font size that text is displayed in which is useful
on some sites. To change this, select Appearance and then Fonts from
the Preferences window.
44. Mouse wheel options
Pressing Alt and scrolling the wheel will navigate back and forward in
the browser history. One can also configure the wheel for other
modifier keys for scrolling and changing the font size.
45. Multiple profiles
Can handle multiple profiles so you can use one for testing, or share
them between multiple persons. You can do something like this in
Windows with multiple user accounts, although it affects all
applications.
46. May be installed quickly and anywhere
Mozilla may be installed on any drive and at any location. It may
installed on a network drive and run directly from there. In fact, it really
doesn't have to be installed at all.
47. Can be easily uninstalled
One can uninstall in the same manner as one does with other
applications.
48. May have multiple versions installed at once
One can have as many different versions of Mozilla installed at once
which is useful if you need to test on various versions.
49. Cross-platform
Mozilla is available for a number of different platforms. (8 to 12
depending on the exact version). It has the same the same features on
all of them. IE only runs on Windows and Mac and supports quite a
different set of features on each. Limited versions of IE for Unix
platforms were available at one time, but are no longer available.
Migrate To New Technology - 8
50. XUL
The XML User Interface Language is used to create complex user
interfaces using markup.
51. XBL
The eXtensible Bindings Language is used to create custom widgets or
elements and bind them to other XUL, XML or HTML elements.
52. RDF
Mozilla can read and manipulate Resource Description Framework
files.
53. MathML
MathML is a markup language for displaying math equations.
54. XPCOM
Native interface accessible via C++ or JavaScript which lets you
perform various Mozilla functions.
55. Properly handles MIME types
Properly displays content using the content type supplied by the server
instead of various other incorrect things. You can learn more
information about this.
56. Supports documents sent as application/xhtml+xml (XHTML)
The debate is still on whether this content type should be used for
XHTML, but Mozilla supports it. Mozilla also supports XHTML sent as
text/xml.
57. Can render XML documents with styling
Can render XML documents with associated style sheets. IE must
convert the documents into HTML before displaying them.
58. Link Prefetching
Mozilla allows one to set documents or images to prefetch in the
background. They are loaded after the document has finished loading
so as to not affect performance. Usually, this would be used for the
next page in a sequence.
More information
59. Displays ABBR/ACRONYM underlined and with titles in tooltips
Content in these tags are displayed with an underline and the titles of
various elements are displayed in a tooltip. (IE does display tooltips for
acronyms though).
Migrate To New Technology - 9
