Wordpress Blog Site
WordPress is a web publishing system (a.k.a. content management
system) written in PHP and founded on a MySQL database. WordPress
is used to manage frequently-updated Web content, especially
Weblogs. It is distributed under the GNU General Public License and is
available free of charge.
PHP (Personal Home Page) Tools is a server-side, cross-platform, HTML
embedded scripting language that lets you create dynamic web pages. PHP-
enabled web pages are treated just like regular HTML pages and you can
create and edit them the same way you normally create regular HTML
pages. Connecting these pages to a database or user input via forms on a
web page makes them able to serve to the end user dynamic content.
MySQL (pronounced "my ess cue el") is an open source relational database
management system (RDBMS) that uses Structured Query Language (SQL),
the most popular language for adding, accessing, and processing data in a
database. Because it is open source, anyone can download MySQL and
tailor it to their needs in accordance with the general public license. MySQL
is noted mainly for its speed, reliability, and flexibility.

Anatomy of a Wordpress site
Blog Site Parts
RSS is a family of web feed formats,
specified in Extensible Markup Language
(XML) and used for Web syndication. RSS is
used by (among other things) news websites,
weblogs and podcasting. The abbreviation is
variously used to refer to the following
Really Simple Syndication (RSS 2.0)
Rich Site Summary (RSS 0.91, RSS 1.0)
RDF Site Summary (RSS 0.9 and 1.0)
Web feeds are widely used by the weblog community to share
the latest entries' headlines or their full text, and even attach
Since mid-2000, use of RSS has spread to many of the major
news organizations, including Reuters, CNN, PR Newswire,
Business Wire, and the BBC. These providers allow other
websites to incorporate their "syndicated" headline or headline-
and-short-summary feeds under various usage agreements.
RSS is now used for many purposes, including marketing, bug-
reports, or any other activity involving periodic updates or
publications. Many corporations are turning to RSS for delivery of
their news, replacing email and fax distribution.

Administration - Posting and editing
A blog entry typically consists
of the following:
Title - main title, or headline, of
Body - main content of the post.
Permalink - the URL of the full,
Post Date - date and time the
post was published.
A blog entry optionally includes
Comments - comments added
Categories (or tags) - subjects
that the entry discusses
Trackback and or pingback -
links to other sites that refer to
Trackbacks & Pingbacks
TrackBack is a mechanism for communication between blogs: if
a blogger writes a new entry commenting on, or referring to, an
entry found at another blog, and both blogging tools support the
TrackBack protocol, then the commenting blogger can notify the
other blog with a "TrackBack ping"; the receiving blog will
typically display summaries of, and links to, all the commenting
entries below the original entry. This allows for conversations
spanning several blogs that readers can easily follow.
Pingback is a method for Web authors to request notification
when somebody links to one of their documents. This enables
authors to keep track of who is linking to, or referring to their
articles. Some weblog software, like WordPress, supports
automatic pingbacks where all the links in a published article can
be pinged when the article is published.
Adding a media file to a post
Notes about media files
Multiple media file types can be added to a post to help satisfy all
users computer capabilities
*.flv files open in a window in the blog post and play with a click
*.mp3 files are music files that play on an MP3 player
*.mov or *.mp4 are Ipod video compatible files
*.avi and *.wmv files are windows media files that play in
Windows media player
In order for an IPOD with I-Tunes to see the audio / video file, the
IPOD capable audio or movie file needs to have the RSS
checkbox selected so that it gets “Included” in the RSS feed.
You can change the order of the files attached to a post - use the
“MOVE UP” button in the Podcasting media files dialog under the
Themes & Plugins
Using themes and the theme system you can make WordPress
look however you want. A few of the more generous members of
the community have decided to create themes for anyone to use.

Plugins are tools to extend the functionality of WordPress. The
core of WordPress is designed to be lean, to maximize flexibility
and minimize code bloat. Plugins offer custom functions and

The term "weblog" was coined by Jorn Barger in December

Why a wiki?
Wiki’s aim to make it easier to author documents, even if doing so limits
the types of documents being authored.
Wiki doesn't make any attempt to do everything that can be done in
HTML - What Wiki does try to do is make it easy to link Wiki to other
"non-wiki" web documents, to embed Wiki pages inside of complex web
pages, and to allow other web documents to easily link to Wiki.
Although this wasn't at all the original intent of Wiki, it became quickly
obvious that WikiWikiWeb principles could be used to make it easier for
groups to collaboratively design and maintain a public web site

Podcasting, a portmanteau of Apple's "iPod" and "broadcasting",
is a method of publishing files to the Internet. It first became
popular in late 2004, used largely for audio files.
Podcasting is the method of distributing multimedia files, such as
audio programs or music videos, over the Internet using either
the RSS or Atom syndication formats, for playback on mobile
devices and personal computers.
The term podcast, like 'radio', can mean both the content and the
method of delivery.
The host or author of a podcast is often called a podcaster.
Podcasters' web sites may also offer direct download or
streaming of their files.
Neither podcasting nor listening to podcasts requires
an iPod or other portable player, and no over-the-air
broadcasting is required. In fact, some believe that
more people listen to podcasts on personal
computers more often than on portable devices
While the name was primarily associated with
audio subscriptions in 2004, the RSS enclosure
syndication technique had been used with video
files since 2001, before portable video players were
Video Blog (Vlog)
A vlog or video blog is a blog (short for weblog) which uses video as the
primary content; the video is linked to within a videoblog post and
usually accompanied by supporting text, image, and additional
metadata to provide context.
With development of RSS enclosures, which provide the ability to attach
media files to a feed item/blog post, it is possible distribute media to the
masses via the Internet.
As of 2006, videoblogging is rising in popularity, especially since the
release of the new Apple Video iPod and the availability of iTunes
Store's video content.
Problems? current inability of search engines to create rich metadata or
"search engine" data from the stream.
For Vlogs to be fully embraced as part of web culture, some indexing
solution will need to emerge.
In early 2000s, various experiments with "video blogging", never
In 2004, Steve Garfield announces 2004 is the year of the
videoblog. There are still only a handful of regular videobloggers.
During the second half of 2004, big media discovers
videoblogging, with articles in the NYT and a few others.
January 2005 - VloggerCon, the first videoblogger conference, is
held in New York City.
May 2005 - vlogdir.com, the videoblog directory launches.
October 2005 - Apple announces the 5G iPod will play video, and
that iTunes Store will serve video content.
February 2006 - Rocketboom(rocketboom.com), popular vlog
earns $40,000 in eBay auction, promising five 15-second ad
spots to ATM maker TRM.
News Aggregator / RSS reader
An aggregator or news aggregator is a type of
software that retrieves syndicated Web content that
is supplied in the form of a web feed (RSS, Atom
and other XML formats), and that are published by
weblogs, podcasts, vlogs, and mainstream mass
An aggregator is able to subscribe to a feed, check
for new content at user-determined intervals, and
retrieve the content. The content is sometimes
described as being "pulled" to the subscriber, as
opposed to "pushed" with email or IM.

The principle is exactly the same as in a loudspeaker, only reversed.
Dynamic microphones are robust, relatively inexpensive, and
resistant to moisture, and for this reason they are widely used on-
stage by singers. They tend to have a poor low-frequency
response, which is advantageous for reducing handling noise as
a vocal mic, but tends to exclude them from other uses.

Web Cam / Video Cam
A web camera (or webcam) is a real-
time camera whose images can be
accessed using the World Wide Web,
instant messaging, or a PC video
Webcams typically include a lens, an
image sensor, and some support
Consumer webcams usually offer a
resolution in the VGA region, at a rate
of around 25 frames per second
(320x200 to 640X480)
Makes it ideal for posting pictures and
video to the web
Installing the Web Cam
Place the driver disk in the computer and
install driver software
Plug in the web cam and let drivers install
Go to My Computer and you should see it as
a device next to the hard drive and CD
From here on, you should be able to get access to
the camera hardware through other programs

The Seven Deadly Camcorder Sins
1. Headhunting--placing every subject in the center of your frame.
2. Motorzooming--overuse of on-screen zooms.
3. Rooting--staying in one spot instead of looking for interesting
4. Firehosing--panning all over the scene.
5. Upstanding--shooting everything from standing eye-level.
6. Snapshooting--taping only two or three seconds per shot.
7. Backlighting--too much light falling on the background instead of
on the subject.
Twelve Helpful Tips for Shooting
1. Use manual focus if your camcorder has it.
2. Set white balance at every location.
3. When shooting outdoors, keep the sun behind you.
4. Plan your shoot.
5. Use a tripod or other image stabilization device.
6. For handheld stability, imagine that your camcorder is a very full cup of
7. Use the zoom to compose your shot. Avoid zooming while the tape is
8. Move the camcorder only when necessary.
9. Shoot to edit.
10. Keep your average shot length between 5 and 10 seconds.
11. Keep the shot steady (no zoom or pan) for at least 10 seconds
12. While shooting, be as inconspicuous as possible to best capture the
true behavior of your subject
The Basic Function of Podcast Autocue
software is to provide a smooth scrolling text
to the reader, who can feed the required text,
set an appropriate speed and other settings,
and then start the Autocue, so that it can

Save Vlog to a Hard Drive or Network: This publishing option saves
your show to an output file on your hard disk or network. You can then
distribute the file however you choose, including copying it to a DVD or
CD with your favorite DVD or CD burning software.
Send video in an email: This method works essentially the same as
saving to a hard drive except that at the end the wizard creates a new
email message and attaches the vlog to it. This requires an e-mail
program such as Outlook Express that is installed locally on the
computer; it does not work with web-based email that you access
through your Internet browser.
Publish video to a server on the Internet: This option is essentially
the same as the Upload to the Vlog Host method, except you must
specify the FTP address to which the file will be posted. Also, this
method does not give you a dialog for adding a link to your blog.
Publish video as a Vlog: Select this option to have Vlog It! post the
