Webcams are one of the oldest tricks on the Internet. Back when Netscape was young, my friends and I used to wander by the fish cam all the time. It is hyped as being one of the oldest live cameras on the Internet, starting on or before September 13, 1994.
If you want to set up a Web cam of your own, you'll need to get a camera and some software. I use a Logitech QuickCam, but you can use any type of camera you would like.
Most of the cameras you buy on the market right now come with webcam software, but if they don't you'll need to get software that will both capture the picture and FTP it to your Web site. I use w3cam for Linux, but the Internet Conferencing site has many other lists of webcam software.
Setting Up the Page
Many people, when they decide to build a Webcam, focus all their time and energy on getting the camera and the software. But the Web page it's on is nearly as important. If you don't have certain things set correctly, your webcam can become a "webcan't".
First there's the image. Make sure:
The image should have a generic filename - no timestamps - I recommend something like webcam.jpg
Know what size image your camera snaps, and use that in the HTML. Don't resize your camera images with the HTML - they are usually fairly grainy and hard to view in the best of times.
Check your FTP settings and know where the image will be uploaded to.
Write your image tag, the way you would any valid XHTML image tag. Include height and width and don't forget the alt text:
Then there's the Web page itself. Your page should automatically reload and it should not be cached. This will insure that your cam viewers get a new image every time. Here's how you do that:
In the refresh meta tag, if you want your page to refresh less often than every 30 seconds, change the content="30" to something other than 30 - 60 (1 minute), 300 (5 minutes), etc. The expires tag is important because it affects the cache of Web browsers, so that the page is not cached but rather pulled from the server on every load.
The Fish Cam is now the oldest live camera site on the web. Reliable sources say that it was online on or shortly before 13 September 1994 Search is on home.netscape.com, type in “the amzing cam”

Reuters and RSS Reuters news and television recently incorporated the use of RSS. So, yes, now you can read the latest headlines from 19 news channels and 4 TV channels in your favorite aggregator. Individuals and non-profit organizations can even display live Reuters RSS Feeds in their web logs or sites. To download and/or subscribe to Reuters RSS feeds, http://www.reuters.co.uk/news.jhtml http://www.reuters.co.uk/newsrss.jhtmWhat is RSS? RSS (Really Simple Syndication) is an XML format designed for sharing web content like news headlines. An RSS service (also known as an RSS channel) consists of a list of items, each of which contains a headline, description, and a link to a web page. For Reuters.co.uk RSS service, the full content, such as a full-text article or video, is made available on www.reuters.co.uk and can be accessed by the link in the RSS service.
How do I use RSS? To use RSS, you will need a special RSS news reader or aggregator that will allow you to collect and display RSS service. RSS news readers allow you to view the service you select all together in the same place and, by automatically retrieving updates, stay current with new content soon after it is published.
There are many different news readers available, many for free. Most news readers are applications that you download and install. Some others are web-based service you sign-up for that work inside your browser.
