RSS Workshop Bryan Bell's RSS Badge

Publish and Syndicate Your News to the Web

"If you build it and have great content, they will come"

Tutorial URL: http://rssgov.com/rssworkshop.html

Workshop Description

In this workshop you'll learn how to create, validate, parse, publish, and syndicate your own RSS news channel. The emphasis will be the practical application of the two most popular varieties of RSS for dynamic publishing.

You can use RSS channels to allow customers to keep up on industry specific news, check weather, look for jobs, view upcoming concerts or university lectures, monitor specific websites, and much more. Some examples of the varieties of applications that government agencies and others have created:

Government Examples

More examples: see RSS in Government blog

 

 

 

 

 

Business Examples

 


This workshop will also teach you how others can incorporate your news into their pages automatically. The workshop will showcase the use of tools that are readily available to you.

What is RSS?

RSS is a protocol, an application of XML, that provides an open method of syndicating and aggregating Web content. Using RSS files, you can create a data feed that supplies headlines, links, and article summaries from your Web site. Users can have constantly updated content from web sites delivered to them via a news aggregator, a piece of software specifically tailored to receive these types of feeds. RSS is the hottest thing in Web communication. It powers many popular applications such as weblogs, knowledge management networks, and news syndication.

Weblogging, a term coined by Jorn Barger in December 1997, is one of the most popular and fast growing applications of RSS. A blog is someone's personal dated 'log' frequently updated with new information about a particular subject or range of subjects.

RSS is changing the world of publishing news and searching for news. Here's how, Chad Dickerson, the Chief Technology Officer at at InfoWorld describes the change:

" I've spent a lot of time in conference rooms patiently explaining RSS to business folks here at InfoWorld and to developers at some other IDG publications, always emphasizing how simple it is: you can do it and here's how. ...It was only recently (April 28, 2003, to be exact) that I felt like RSS had completely turned the corner at InfoWorld when the various constituenices at InfoWorld (sales, editorial, and technology) agreed to include links to our feeds prominently on our home page. Getting something on the home page is recognition that something has been politically mainstreamed within an organization. So, what's my point? RSS is now burned into InfoWorld's organizational brain like the words Kleenex and Xerox. Names can change, specs can change, people involved can change, and any number of other things can change, but in the end, if any of the business folks ask me.... I'll just say: don't worry about the name, it's really just RSS...." Source.

RSS 0.91 (Rich Site Summary)

Netscape released version 0.91 xml rss feed in July, 1999 and has since been upgraded by Dave Winer of Userland to 0.92 xml rss feed, and in August 2002 to 0.94 and 2.0 xml rss feed. The latest version is the first to support extensionability with optional namespaces in its first module, blogChannel. For more detail see Ben Hammersley's Content Syndication with RSS, chapter 4 (pdf) and chapter 8 and Sam Ruby's RSS in Depth with Quick Summary.


RSS 1.0 (RDF Site Summary)

RDF or Resource Description Framework, provides an XML structure for describing document metadata content. The RSS-DEV Working Group created RSS version. 1.0 (official specification) in December 2000 supporting RDF thus allowing the description and syndication of site content and metadata. It differs from the earlier version because of its extensibility via modules based on XML-Namespace technology. This lets content providers use it in their own documents plugging functionality into a basic syndication platform, saving time and effort, and ensuring compatibility. RSS 1.0 documents can draw upon any RDF-compatible extension syntaxes called modules. Current standardized modules exist for Dublin Core, Syndication, Content, and Annotation. For more detail see Ben Hammersley's Content Syndication with RSS, chapter 6 and Sam Ruby's RSS in Depth with Quick Summary.

.

What Does a RSS File Look Like?

It's a good idea to learn how an RSS file is structured before you begin creating them. RSS files are written in XML [this orange XML logo is used to represent a link or pointer to the syndicated form of a news feed].

Let's take a look at and compare the two flavors of RSS:

XMLHack ..................... 0.91 xml rss feed | 1.0 xml rss feed
Dive into Mark .............. 2.0 xml rss feed

tima thinking outloud ..... 2.0 index xml rss feed |
2.0 full xml rss feed | 1.0 xml rss feed

Some things both formats have in common:

  • the XML declaration: <?xml version="1.0"?>, often including the encoding scheme
  • channel elements:
    • title - the name of the channel
    • description - a short description of the channel
    • link - an HTML link to the channel Web site
    • language/dc:language - the language encoding of the channel (for example en-us)
    • image - an optional link to a site logo
  • one or more item elements with titles, links, and descriptions

Notice the differences. The1.0 version feed is wrapped in the RDF namespace declartion, <rdf:RDF> ... </rdf:RDF>,, has a table of contents in the channel block (used by aggregators), and employs Dublin Core metadata fields.

Want to know the full details about the various elements used in 0.92 feeds? See Matthew Trump's RSS 0.92: A Step-by-Step Beginner's Guide. and Mark Pilgrim's article What is RSS?

RSS 1.0 conforms to the W3C RDF specification. RDF is a model for describing metadata for describing resources from a collection of web sites, a single web site, parts of web pages, a specific HTML or XML element, documents, printed books, recipes, etc. A property is an attribute or characteristic used to describe a resource and is specified in the RDF Schema specification. The resource together with a named property plus the value of that property is an RDF statement. All statements are enclosed in an RDF element which has a namespace prefix pointing to the RDF syntax specification:

<?xml version="1.0"? encoding="UTF-8"?>
<rdf:RDF xmlns:rsdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"</rdf:RDF>

The RDF schema, calls for each channel to have a title, description, link to the channel on your Web site, and then item elements. You can include optional information about the channel: language, PICS rating, copyright statement, pubDate or publication date of the channel, lastBuildDate showing the date it was last updated, docs, link to the managingEditor, link to the webMaster, an image such as a logo, textinput strings, skipHours telling automated aggregators when not to collect RSS data, and skipDays telling aggregators days that data should not be collected.

News stories in your RSS feed are items defined by the <item> tag and usually containing a headline <title>, the URL to the RSS feed or <link>, and an optional <description>. RDF feeds were traditionally limited to 15 items, but that limitation is largely a matter of convention. Syndic8's Headlines Per Day shows that some feeds can number in the hundreds, but keep them reasonable so they readily load into feed readers.

Don't put HTML markup code within a headline. If necessary in a description, such as for a link, the HTML characters &, ", <, and > will need to be encoded as &amp;, &quot;, &alt;, and &gt; . The RSS 2.0 specification specifically allows it. Ben Hammersley argues against putting HTML coding in description for two reasons. It requires that client software have the ability to parse it, and combining presentation markup along with the content diminishes the ability of RSS in being able to provide indexable metadata.


Find a Viewer to View RSS Channels

To get acquainted with RSS, we'll first view a RSS channel through a RSS reader or viewer. In this workshop, we'll view ResearchBuzz (0.91) xml rss feed and Perl News (1.0) xml rss feed using an online viewer and a client-side news aggregator. Try this exercise:

    1. Go to UKOLN's RSS-Xpress RSS channel viewer and editor.
    2. Click view to see the HTML presentation. Click "edit and then "save" or "source" to view XML.
      Optional: For comparsion, view Perl News using Redland RSS 1.0 Viewer. Check "yes" to format the results in a simple box.

    Now we'll find these same two feeds in Syndic8, the largest RSS syndicator. Notice the tabs at the bottom of the page. Click "headlines" to read the current feed. Click the "integration" tab to access files prepared for several other alternative readers including NewsIsFree, Headline Viewer, Fyuze, Radio Userland, Snewp, Amphetadesk, and BottomFeeder.

    Let's take a look at one of these client-side readers that you may wish to install on your computer:

    Andrey Tumashinov's NewsZCrawler – ($25). This Windows reader has many features and is easy to set up. It synthesizes RSS news feeds, NNTP newsgroups, and news web sites. It can write as well as read news.

    See our Searching RSS Channels for News Workshop for information about other spiffy news aggregators that you can download and configure.


Create your own channel and news headlines

You can create a RSS file using any text editor, but you almost certainly will find syntax errors. You may find it preferable to create channels using one of these editors and then maintain them using a text editor. This isn't a bad practice, if the channel is for something ephemeral. If the channel items are not archived and if the channel isn't integrally associated with a particular site, editing the channel with a text editor is easy and fast. Otherwise, you'll probably prefer to use a content managment system (CMS) tool to maintain channel data.

In this workshop, we are going to construct a simple RSS channel. We're going to start with "Documents in the News" a news page constructed in standard HTML by Government Documents Librarian, Peter Kraus, at the University of Utah Marriott Library. The "before" page is the page as it existed on September 24, 2002, and "current" is the page as it currently exists.

When you're done with today's workshop, you will have created a RSS channel (either in 0.9 or 1.0 xml rss feed ) and you will have published the same page with the information now dynamically appearing as an RSS channel (style sheet optional).

We'll create a channel for "Documents in the News" by using the first two tools listed here:

  • UKOLN's RSS-Xpress by Andy Powell and Pete Cliff is a superb web-based RSS channel editor and directory. RSS-xpress editor forms RSS 1.0 XML, but is currently restricted to 15 items per channel. Click "add event details" for additional fields. Edit, save files locally, then load them to your server. Nice for distributed RSS content management.
    "Documents in the News" RSS example - xml rss feed


  • WebReference's RSS Channel Editor - like UKOLN's, this editor is limited to 15 items, but this online form will generate valid RSS 0.91 feeds. Build a new channel or "fetch" an existing one, click "build RSS," and then save the resulting file. A similar web-based generator that can be used to construct RSS 0.91 feeds is Andy Holt's RSS Headline Generator.

If you're interested in more than an individual channel, then you're better off using a blogger or content management product that use RSS. Most support automatic archiving to store old posts, permalinks (to link to them), date headers and time stamps that record when new headlines were posted. Some provide hosting for you site for free or for a low cost. Some require a client-side download; some are managed entirely through a web interface. [Suggestion: include a "generator" comment line such as <!-- generator="Movable Type/2.51" --> on the line following the XML declaration. This allows Syndic8 and others to track the usage of these tools.]

Here is an incomplete list that links to several of the more popular alternatives.

  • Blogger Products is a server-side product line, including subscription services, for creating RSS 0.91 feeds. Blogger Pro has spellcheck, image uploading and team blogging. Blogger is a creation of Evan Williams and Meg Hourihan of Pyra and is generally credited for first popularizing blogging. Pyra was recently purchased by Google.

  • Radio Userland - Dave Winer's easy-to-use blog host with client-side CMS product for Windows and Mac with facilities for creating, reading, and archiving RSS feeds for a single blog. It can be made collaborative by use of the Multi-Author Weblog Tool. It is designed to be used from one main location, though updates can be remotely if you have remote access to your workstation. Manilla is a server-side product that supports building a community of blogs and Frontier is the overall CMS.

  • Movable Type by Benjamin and Mena G. Trott -- popular and feature-rich, extensible, server-based Perl CMS, free for personal or non-profit use; $150 for government agencies Commercial Pro version due out in summer. Easy to use for maintaining regularly-updated news or journal sites, like weblogs. Supports XML-RPC and creates custom 0.92 and 2.0 (.xml) and 1.0 (.rdf) RSS channels. Supports the creation of "collaborative weblogs", i.e. multiple authors and visitors can contribute postings and/or make comments. Has language packs that translate the display into other languages such as Spanish. Imports Radio Userland created channels and archives, but comments are lost. Must have server access. Example of a subscription list. Utilizes "trackback pings" enabling you to see all sites that have referenced a post on your site and to read related posts (trackback example) enabling distributed communications. See admin interface screenshots.

  • Typepad - Ben and Mena Trott's centrally hosted commercial weblogging service. It's like using Movable Type only easier and with some unique features.

  • NewZCrawler - this client-side news reader also creates outgoing channels in RSS 0.92 to which you can add your news using its news composer (template-based news feed output allows you to create any output text format). If you have a webblog, the program also has a Blog Client allowing you to post news via the blogger XML-RPC API.

  • News Is Free - Once registered, you can register multiple channels and manage them simultaneously using their online "Post to Your Blog" editor.

  • Onclave - a free web-based system in beta testing by Drew Peloso, Dave Reid, Steve Hatch, and Per Kreipke for creating and managing multiple online collaborative weblogs, managing the information with directory-like taxonomies. Users can put information into appropriate categories, or create new topics as needed. You can create RSS 0.91 channels by creating a personal or collaborative (cblog) onclave, adding a weblog channel, and syndicating as RSS. There is no software to download. Publishing is done dragging the Share-it! editor to your browser toolbar. When you see an article you want to share with others, click Share-it, enter the item title and description, and click publish. Click the syndicate button to create the RSS XML file or the simple javascript code to parse and display the channel to your site. Visitors can subscribe by email to your syndicated channel by clicking the notify button and you can post entries by email. gilsUtah example. - receive channel by email.

  • WebCrimson - content management tool by John Hiler's company for free, easy-to-use online browser creation of a "weblog" , adding a weblog to an existing site, creating a WebZine on your site or hosted on theirs, or contribute "articles" using browser editor. Includes full FTP, templates, WYSIWYG editor, permissions and admin contro for group contributions, and optional hosting on their servers.

  • pMachine Free - free PHP product and hosting service that supports collective weblogs and installs, like Movable Type, on your own server. The commercial pMarchine Pro supports multi-layered interactive news sites.

  • Blosxom - a free lightweight, yet feature-laden weblog creator by Rael Dornfest; in Perl (runs on any OS, but built to take advantage of the Mac OS X). Possibly the most useful "61 lines of code" on the Internet. A simple PERL plug-in by DJ Adams allows you to post entries by email. Pyblosxom is a python version (Abe Fettig's example).

  • Noah Grey's Greymatter [mirror] - free opensource Perl, server-based weblogging and journal software.

  • Tidakada.com's B2 - a PHP4 open source blogging tool that creates RSS 1.0 and 2.0 feeds. Pages are generated dynamically from a MySQL database.

  • LiveJournal - a large weblogging hosted community whose servers can host your online journal. Their downloadable client software supports Mac, Windows, BeOS and UNIX.

  • Byline - an open source Python weblogging system that can operate in either a client-based or server-based mode, but lacks a web-based interface

  • Textpattern - a PHP/mySQL content managed blogging system currently in beta.

  • Syncato - Kimbro Staken's weblogging system that stores posts in an XML database (Requires Python and Sleepycat Berkeley DB XML)

  • PyDS (Python Desktop Server) - George Bauer's combined Weblog authoring tool, XMLRPC/SOAP server, and news aggregator (Requires Python).

  • Blogware - Tucows' new weblog platform software available only through a licensed Blogware Reseller.

  • Serence Corporations's KlipFarm - register as a Klip Provider to make channels. The service also has an alert service, an XML-based Windows desktop application that grabs streaming RSS feeds, and Klip Folio, a free Windows client-side viewer that you can download.

  • Tom Dyson's Mailbucket - some aggregators allow you to post entries to a blog via email. Mailbucket is an experimental email-to-RSS service that allows you to create a public RSS 1.0 feed and post to it by email. Perhaps useful for creating mailing list feeds.

  • Some popular open source, server-side, portal content management systems such as PostNuke, (php), PHP-Nuke,(php) phpWebLog (php), SlashDot (Perl), Squishdot (Zope), Rusty Foster's Scoop (Perl), Roller (Java), and Drupal (php) can also create and display RSS feeds using their built-in news aggregators. They are very popular for community sites. Scott Johnson has a tutorial for creating feeds using Drupal. Both Drupal and Scoop can support multiple blogs and Drupal have a module for customized news aggregation. Here are two of my favorite community implementations:

A handy tool for comparing features between over 25 of the more popular RSS creators is:

Machine Created RSS Channels

Content created in HTML by yourself or others can be converted to RSS feeds by means of "scraping". Scrapers try to identify "headlines" in a page and they create feeds that are OK but not of the quality of human produced feeds. You can use one of the free online scraping services or download their source code to your own server and run a scraping service of your own.

You can assist these scraping programs by putting special span tags around content that you want syndicated. The text inside the tags is pulled out and put into an RSS file.

Put <span class="rss:item"> ... </span> tags around any items on a page that you want to syndicate by RSS (such as a list of links or events).

Then submit the URL to:

    Ian Davis' myRSS is a python program that converts web data into XHTML RSS channels. Enter a web page URL in the Create a Channel form.. Channels are created in RSS 0.91, RSS 1.0, and in javascript include formats, and are updated daily. myRSS delivers, using a heuristic algorithm, the last 15 headlines or hyperlinked resources that have been added to the page. This could be a very useful tool for syndicating a site what's new page, agency news, new acquisition lists, donations received, and the like. A myRSS style sheet can be associated to a feed if you wish to display a myRSS channel on a page. The services uses item link redirects on the myRSS server that in turn link to the referred to resources. Anyone can "sponsor" a channel for a $10 annual fee and have the redirect links removed. Anyone can pay $25 per year to have a channel updated hourly instead of daily. Noteworthy channels created in this manner are reviewed, and if acceptable, are annotated and are included in the DMOZ Open Directory project and in Syndic8.com's database. You can download the entire myRSS Channel Catalog in OCS, an xml format for describing channel catalogs. MyRSS turned this workshop into these two RSS 1.0 xml rss feed xml rss feed channels; new items posted to the State of Utah homepage are in this xml rss feed channel.

    Syndic8 Syndicate Your Page- an online form to generate the feed and list it with the Syndic8 aggregator. What to syndicate content created by someone else? Use the Syndica8 "suggest" service to create channels using myRSS.

    RSSify at Voidstar.com - an online form by Julian Bond to generate a RSS 0.92 feed

If you want to do the creation yourself, download and install either:

    Blogfeed. - a Perl script from Adam Kalsey's Consulting Group

    RSSify - a PHP script by Julian Bond that creates RSS 0.92 channels with up to 25 items.

    Eric Vitiello's Slurp - a downloadable Perl script that retreives HTML pages and converts them into RSS 1.0.

Some tools specific to Radio Userland are:

  • eVictor's rssDistiller - a commercial tool for RadioUserland that extracts RSS feeds from most HTML pages and allowing you to join the results of several filters into a single feed. For example, Bruce Loebrich has used this tool to creat RSS channels from Google News xml rss feed and Columbia University Newsblaster xml rss feed syndications.

  • Mark Paschal's Stapler - a Radio Userland RSS extractor tool


Validate Your RSS

As a channel editor, it is your responsibility to ensure that your file can be parsed by the XML parser of any subscribing site. Your RSS creation software should validate XML at the time of creation, but some do not. Minor errors can make the feed unreadable. You may wish to load your RSS file to your server and then enter the URL in one of the following validators to check the syntax.

  • Feed Validator (formerly RSS Validator) by Mark Pilgrim and Sam Ruby. Version 1.2.3 now validates multiple syndication formats: RSS 1.0, RSS 0.9x/2.0, and the new Pie/Echo/Atom 0.2 feeds. It includes validation for common namespaces. If you have access to a server with a Python distribution, you can download the open source code and follow the instructions to install it locally.


  • Dave Becket's Redland RSS 1.0 Viewer. RSS to HTML converter, but acts as a RSS 1.0 validator also. Viewer offers several parsing methods. Links to a great collection of feeds about RSS.

  • Experimental Online RSS 1.0 Validator. The Schematron is by Rick Jelliffe and the report by David Carlisle modified by Leigh Dodds validates for namespace, core structure, core content, field lengths, RSS 0.91 module structure and content, and Dublin Core module structure. Leigh's beta test validator further checks core modules and some proposed modules.

  • Userland RSS Validator - for RSS 0.91, RSS 0.92

.

Parse and Display Your RSS Channel on Your Site

Since RSS files are written in XML, you cannot readily display them in a page without parsing them for the information you want to show. Content management and blogging systems like Radio Userland, Movable Type, and Drupal automatically parse and publish this to your site without any extra effort on your part.

If you are using a text editor to create channels, or if you want to display your RSS content on another site such as one created with DreamWeaver or Frontpage, you'll need to insert an "include" that calls upon an external parsing program.

These parsing programs coupled with stylesheets allow you to display this content the way that you want it to appear. You can choose the fonts and colors, the number of channel items to display, whether or not to show the headline summaries or descriptions, and whether or not to show the time/date stamps. Parsers will allow you to display multiple channels, if you so desire, all on the same page.

There are many solutions to choose from. In many cases all you need to do is to put a single-line javascript into a page, connecting the location of the RSS channel to the location of the parser. If the feed already exists as a javascript (.js file), you just need to call it. For example, to display the LockerGnome daily tip just insert:

<script language="JavaScript" src="http://www.lockergnome.com/syndicate/tip.js"></script>

Which displays as:



Other examples:

<script type="text/javascript" language="javascript" src="http://www.epnworld-reporter.com/news/headline_feed.php"></script>

<script language="javascript" type="text/javascript" src="http://agency.utah.gov/cgi-bin/parsername.cgi?rss=http://agency.utah.gov/rsschannelname.xml"></script>

<script type="text/javascript" language="Javascript" src="http://mkdoc.com/news/headline.js"></script>\

You may want to include a NOSCRIPT option for users who either have javascript disabled or who are using screen readers. Kansas City infoZine uses a javascript include that looks like this:

<script language="JavaScript" src="http://rss.infozine.com/feed/rss2js.php?src=http://rss.infozine.com/kc/headlines.xml">
</script>
<!-- alternative for no javascript -->
<noscript>
<a href="http://rss.infozine.com/feed/rss2html.php?src=http://rss.infozine.com/kc/headlines.xml">View infoZine Headlines</a>
</noscript>

 

Some scripts will allow you to use style sheets to customize the look and feel of the channel to match that of your site.

Here's how the process works:

Start with empty page shell

add the channel by inserting the javascript

attach the link to the - style sheet , and

voila!

You have two choices. You can either install one of these parsing programs on your own server, or you can point the "include" to a script residing on someone else's server. Let's test the waters first by pointing to a parser on another server. Here are a few options:

Adam Curry's RSS-Box Viewer [mirror] - a service in beta that parses all versions of RSS. Use the online form to select table size, fonts, colors, maximum item numbers, and whether to display compact or expanded. It then creates the javascript with embedded variables. Supported stylesheet classes are: .rssBoxTitle, .rssBoxContent, rssBoxItemTitle and rssBoxItemContent. Write to Adam for the full code if you want to host it locally (written in Rebol, an Internet messaging language). The script to insert, for our "Documents in the News" example, looks like this:

<script language="javascript" src="http://publish.curry.com/rss/rss-box.r?url=http://gils.utah.gov/secure/rss/kraus91.rss&align=
left&width=350&frameColor=white&titleBarColor=%23ffffff&titleBarTextColor=cc0000&boxFillColor=white&textColor=
black&fontFace=Times New Roman&maxItems=7&compact=&xmlButton=&javascript=true"></script>


"Documents in the News" demo - XML - stylesheet



RSSxpress-Lite by Andy Powell and Pete Cliff of UKOLN. Click "try it" and Select a channel - -
Enter the URL of the channel that you just created and loaded to your server. It produces a line of javascript that you just cut and paste. You can use style sheets to customize the colors, fonts, and display. Support documentation. For example:

<script src="http://rssxpress.ukoln.ac.uk/lite/viewers/rss.cgi?rss=http://slashdot.org/slashdot.rdf"></script>

After you have tried this, you'll probably want to load a script to your own server so that you have more customization options and assurances of reliability. Most are open source and free to download and use, and they come in a wide variety of programming languages.

Our RSS Parsing Programs page describes many of these options with links to working examples, documentation, and the urls where you can download them.

Allow other Sites to Publish Your RSS Channel

You'll want to let others read your channel and publish it to their site. Syndication is the process of sharing content among sites. This other other websites and applications to include your updated headlines. Websites should create an information page, about syndicating their headlines. One standard that was created by UserLand and is being used increasingly is to include this XML image somewhere on your site and link it to the RSS XML for that page. To publish other feeds on your site, first check licensing agreements; an example is that of MagPortal.com.

Another thing you can do is to allow people to subscribe to your site by email. Onclave supports this as well as:

Bloglet - a super slick XML-RPC, RSS-to-email conversion subscription service by Monsur Hossain for the blogs you create. Allows others to receive email subscriptions of your blog and you can receive daily stats on your subscribers. Also can be used to stay up-to-date on your favorite sites by subscribing to any existing RSS feed. Add a subscription box to your site, for your own or anyone elses channel. It creates the code to add. Use the FeedMe toolbar icon to automatically subscribe to feeds that incorporate auto-discovery. For example:

Enter your email address below to subscribe to Utah and National Public Library News!xml rss feed

Register Your Channel with a RSS Aggregator

Before going public, proofread to make sure that your channel has a correct URL link, descriptive title, and an informative and accurate description. DMOZ weblog editor, Laura, has compiled some useful tips.

Next, submit your channel to aggregators just as you would submit your website to search engines. You'll be amazed at the traffic it will generate.

An aggregator is a web site or system that collects RSS feeds from multiple sources and then does something with them. Usually this will involve collating and displaying the contents of each feed and perhaps creating new composite feeds from them. Here are a few of the larger aggregators:

  • Syndic8 - the largest aggregator with almost 10,000 feeds-- recommend your own or another's; created by Jeff Barr

  • Userland

  • OnContent - add your feed to their database and use their server to syndicate your content; registering allows you to display feeds from there on your own site

  • Calaba's XMLTree - a directory

  • NewsIsFree - by Mike Krus has headlines from a fast-growing collection of more than 3,600 feeds.

  • News4Sites - a commercial aggregator that monitors 8,000 web pages from 2,500 domains producing more than 25,000 news headlines organized into over 2,200l channels of up to 20 headlines per channel. Feeds are generated in ten formats: javascript, RSS, PHP, ASP, C#, VB.NET, WDDX, XML RPC, CDF, and PERL. They can be parsed or delivered by email. The feeds are available for free with advertisements. Suggest a site for inclusion.

  • Submit a Weblog to the EatonWeb Portal - search for over 8,000 RSS channels or browse by category

  • Daypop - if your channel offers news or current events, add to this excellant Google-like search of over 7,500 news feeds. Use Daypop Backlinks to see who is linking to you.

  • Shanti Braford's PopDex: the website popularity index - crawls sites and analyzes links to rank the most popular stories from Internet news sites, blogs, and weblogging resources. Use Popdex Citations to see who is linking to you and Searchbox to search other blogs from your site. Email Shanti.

  • Backwash - a PHP driven community site of independent columnists who recommend the best specific Internet content. Bills itself "the ultimate recommendation engine." Register and then submit.

  • Morton Frederickson's Syndication Subscription Service consolidates the multiplicity of aggregation services. A green subscribe icon subscribe - subscribe on a page will take you to a page (example) that lets you choose the subscription link for the aggregator of your choice. Clicking the icon there will add the linked RSS feed to your subscription list.


Some of these sites provide categorized lists of their channels in OCS (Open Content Syndication) and OPML (Open Processor Markup Language) formats. OCS is an xml format for describing channel catalogs.

.

Use Auto-Discovery Aggregation

You can facilitate aggregators finding your channel by inserting a LINK specification within the HTML <head> that tells the location of your RSS feed. If your tool hasn't already implemented this, you can add this a simple one-line statement using the HTML link tag:

<link rel="alternate" type="application/rss+xml" title="RSS" href="http://yoursite.com/rss.xml">

Some real world examples by Rael Dornfest and Mike Krus:

<link rel="alternate" type="application/rss+xml" title="RSS" href="http://www.oreillynet.com/meerkat/?_fl=rss10" />
<link rel="alternate" type="application/rss+xml" title="XML" href="http://www.newsisfree.com/news/index.rdf">

Each RSS feed that you have should have its own defined LINK tag with its own unique title.

Mark Pilgrim's Auto-subscribe Bookmarklets. Drag the link to your link toolbar and whenever you visit a site that you want to add to your news aggregator of choice, click your "Subscribe" button on your link toolbar, and it will try to find the site's RSS feed and auto-subscribe you. Nifty!

Likewise, Onclave comes with a Share-It bookmarklet and the latest version of Movable Type comes with a "MT It!" allowing you to use the bookmarklet from your right-click menu.

More and more news aggregators and programs are supporting auto-discovery including:

  • NewsIsFree - If you create an account with this headline aggregator by Mike Krus, you can use the web site as a cloud-based personal aggregator. Any of the feeds it collects can be added to custom pages that you define. Their OCS Service List is an XML of exportable RSS channels.

  • Jeff Barr's Syndic8

  • LiveJournal, a collaborative open source free service for most platforms allowing you to create an online journal from syndicated feeds. Once you've created a journal, add /RSS to the end of the URL to view it in RSS format.

  • Rael Dornfest's Meerkat

  • Drupal has a powerful built-in site-cloud News Aggregator for reading and blogging news from other sites.

  • Joe Gregorio's Aggie 1.0 RC3 opensource, native .NET newsreader. Enter a URL of a web page into the Add Channel box and if the web page supports auto-discovery Aggie will find its RSS file.

  • Keith Devens' PHP RSS Aggregator

  • BlogLinker.com is a unique free tool from Zaeem Maqsood.for reciprocal linking and increasing traffic to your site. Register, insert a javascrfipt and add links. If the website you link to is also registered, then your site will automatically appear in their list of links.

  • Mark Pilgrim, of dive into mark, has created autorss.py, a Python script to find a site's RSS feed and to search for a referring site's RSS feed in auto-linkbacks. It can be used programmatically (the autorss.getRSSLink function) or on the command line:

    [f8dy]$ python autorss.py http://diveintomark.org/
    http://diveintomark.org/xml/rss.xml

  • Technorati - enter the URL of your page and it will show you the pages currently linked to you ranked by "blog authority" and "freshness." For a fee, create a "watchlist" based on your own URL or search terms and and have Google send you a daily email or RSS feed..

  • Julian Bond's GNews2RSS - a free online form (and PHP script that you can put on your own serve) that will that will perform a Google News search query and turn the results into an RSS feed.

  • Phil Pearson's Blogging Ecosystem - analyzes links between members of weblog communities. It scans nearly 14,000 blogs and lists the 501 most popular blogs (by back links) and the blogs that each listed blog in turn links to (forward links). Use it to check blog popularity and to see who is linked to whom. For example, at this writing, Phil Windley's Enterprise Computing is the 220th most popular because 74 others link to it. Calculates nearest neighbors, levels of linkedness, degrees of separation between any two blogs.

See the DMOZ RSS Autodiscovery category for more links.

The CGI Resource Index has links to a considerable number of PERL programs, such as Moreover's News Fetcher, that allow you display headlines from other RSS feeds on your site.

Conoce alguien de un ATA inalámbrico ?

Anyone know of a wireless ATA ?

Q / I have a project to interface an ATA to "standard" security alarm panels. I have already got quite close with an Sipura SPA3000 ATA, however, a potential marketing company want a "plug and play" solution where all the customer has to do is unplug the RJ11 from their existing alarm monitoring, connect it into an ATA, power up the ATA and that's it. They do not want the customer to start running ethernet cables through their homes to a router that is in the lounge one week and a bedroom the next. The only wireless ATA I have managed to find so far is from a company called SMC. It has custom tone generation (which I require), but it does not have remote provisioning - which would be nice. Anyone know of another wireless ATA ?

**Please note I am not sending DTMF over a VoIP channel. I use IP dialing to send data via UDP.

Steve N.

A/ Steve:

You could connect your SPA3000 to a WBP54G and it (SPA3000) will be a wireless ATA. Yo can buy it from amazon.com for about US$38.

Apple Introduces Innovative Cellphone

By JOHN MARKOFF

Published: January 10, 2007

SAN FRANCISCO, Jan. 9 — With characteristic showmanship, Steven P. Jobs introduced Apple's long-awaited entry into the cellphone world Tuesday, pronouncing it an achievement on a par with the Macintosh and the iPod.

Apple

Apple iPhone.

 

The creation, the iPhone, priced at $499 or $599, will not be for everyone. It will be available with a single carrier, Cingular Wireless, at midyear. Its essential functions — music player, camera, Web browser and e-mail tool as well as phone — have become commonplace in hand-held devices.

But it was the ability to fuse those elements with a raft of innovations and Apple's distinctive design sense that had the crowd here buzzing.

Apple's goal, Mr. Jobs said, was to translate the Macintosh computer's ease of operation into the phone realm. "We want to make it so easy to use that everyone can use it," he said. And he was clearly betting on translating Apple's success with the iPod music player to a hot category of multifunction devices.

Underscoring the transformation of a quirky computer maker into the dominant force in digital music, and signaling his ambitions to extend that reach, Mr. Jobs also announced that Apple was dropping "computer" from its name and would henceforth be known as Apple Inc.

Investors took quickly to the pitch, sending Apple's stock price up to a record close, while shares of established cellphone makers slumped.

Still, the phone is a gamble on a new business for Apple. And even with its success with the iPod and a reborn line of computers, it has not been immune to marketplace failures, like the Macintosh Cube introduced in 2000.

But in his two-hour presentation before an audience of reporters, analysts and Apple employees at the Macworld Expo trade show, the parallel he repeatedly drew was between the new phone and the Macintosh personal computer, which had a vast impact on the computer industry when it arrived in 1984.

Noting that there are occasionally new products that change everything, Mr. Jobs said, "Apple has been able to introduce a few of these into the world."

He said Apple had set the goal of taking 1 percent of the world market for cellphones by the end of 2008. That may seem small, but with a billion handsets sold last year worldwide, that would mean 10 million iPhones — a healthy supplement to the 39 million iPods that Apple sold last year.

"Steve can make the internal combustion engine appear to be something new and cool," said Reed E. Hundt, the former commissioner of the Federal Communications Commission. "He will provide a certain magic even to the 30-year-old cellphone."

Mr. Jobs's product tour de force was even more remarkable for its timing, as questions continue to be raised over the company's stock options practices and his role in them.

"The truth of the matter is everything is fine," he said during an interview after his presentation. "We've shared it all with the S.E.C."

He acknowledged the controversy over the timing of some of Apple's stock option grants, which Apple appears to have fanned recently with a disclosure to the Securities and Exchange Commission that contained a circumspect description of his role in the options award process.

"It's raised questions," he said, "but some of the journalism has been so off the mark. But I know the truth. It's painful to read some of this stuff, but I know it's kind of ridiculous and will pass."

If he is in any trouble, Mr. Jobs showed no signs of it either on stage, where he was treated with great warmth by his audience of 4,000, or in an interview afterward in which he showed obvious delight in highlighting subtle industrial design features.

Mr. Jobs showed a series of applications including e-mail, advanced voice mail, photo collections and visually appealing Web searching. He promoted the fact that the new iPhone is powered by the same core OS X operating system that the Macintosh computer is based on, offering power-management features and advanced graphics abilities.

The user interface relies heavily on a high-resolution touch screen that makes it possible to use a finger to control the phone. It has features that are still more subtle, including sensors that track light and movement and proximity, to prompt the phone to control screen brightness and physical orientation and other aspects of its operation. For example, when the phone is placed next to the user's face, the keyboard is automatically turned off.

Apple chose the name iPhone even though Cisco Systems, the network and consumer wireless company, has recently introduced a Wi-Fi-based phone with the same name. Mr. Jobs had been negotiating with Cisco executives over the trademark in recent days.

The $499 version of the device will have four gigabytes of storage, and the $599 version will offer twice that.

"At $499 and $599, it's a pretty expensive deal," said Rob Glaser, chief executive of Real Networks, whose online music store is a rival of Apple's iTunes Store. "Steve is more focused on not cannibalizing iPod sales than on driving volume of phones. Those are not high-volume prices."

Mr. Jobs defended the higher price of the new phone in a market where prices of so-called smartphones — those combining voice calling with Internet functions — are rapidly plunging to $200 and below. He contrasted the iPhone, which has only one mechanical button on its surface, with the BlackBerry and smartphones from Motorola and Palm. Rather than what he called "small plastic keyboards," the iPhone will have a display that becomes both the keyboard and control panel, morphing to suit the current application.

"After today I don't think anyone is going to look at these phones in the same way," he said.

Apple's relationship with Cingular began two years ago when Mr. Jobs phoned Stanley T. Sigman, Cingular's chief executive, and proposed that they speak about a relationship. The two had an initial meeting in February 2005 in a New York hotel.

Apple spoke with other carriers before committing itself to its exclusive link with Cingular, Mr. Jobs said, but he would not give details.

In addition to the Apple relationship with Cingular, which Mr. Jobs said was forged without offering the wireless carrier even a peek at an early prototype, the iPhone will offer special applications from both Google and Yahoo. Users will be able to use both services' search and e-mail services as well as a custom version of Google Maps.

Eric E. Schmidt, who is chief executive of Google as well as a member of Apple's board, and Jerry Yang, co-founder of Yahoo, came on stage to endorse the new hand-held.

"I'm not a board member of Apple, but I would like one of these, too," Mr. Yang said.

Regis McKenna, the veteran public relations specialist and corporate strategist who tutored Mr. Jobs in the art of high-tech marketing beginning in the late 1970s, said: "This compares favorably with the launch of the Macintosh. The price is high, but it will come down."

Despite the widespread comment and enthusiasm that the phone generated, there were also many questions about its design and about Apple's strategy.

Some analysts and industry executives noted that the Apple designers had shunned Cingular's higher-speed digital cellular network. Mr. Jobs said later models would have additional networking standards.

Others questioned whether the device would be as versatile as other smartphones if it was not truly open — that is, able to accommodate many programs from third parties, as personal computers are.

Mr. Jobs would not say how open the phone would be to other developers, but added: "I don't want people to think of this as a computer. I think of it as reinventing the phone."

He also said he was anxious to help protect the Cingular network from the kind of viruses and worms that bedevil the PC world today.

The phones will go on sale in June through Apple and Cingular (online, by phone and in stores). Mr. Jobs said the phone was being announced ahead of its availability to head off disclosure that might have resulted in the course of Federal Communications Commission licensing.

Although it will be a half-year before it is possible to know whether Mr. Jobs has another hit product, there was no shortage of enthusiasm based on the first glimpse today.

"It's like they read our minds," said David Myers, executive chef at Sona restaurant in Los Angeles and chief executive of the Food Arts Group, where the employees currently use the Treo smartphone from Palm. "This is the next step in not accepting poor design any longer."

Before he introduced the phone, Mr. Jobs said Apple TV, the digital video system that he announced as iTV last year, would be available for $299 in February. The device will store up to 50 hours of video and permit wireless streaming of content from a computer to a television.

New Mobile Phone Signals Apple's Ambition

Published: January 9, 2007

SAN FRANCISCO, Jan. 9 — Steven P. Jobs introduced an Apple wireless phone today that he said would lead to a new synthesis of communications, video, music and computing.

Steve Jobs, Apple's chief executive, said the iPhone would "reinvent" the telecommunications sector.

Paul Sakuma/Associated Press

Steve Jobs introduced AppleTV at the MacWorld Conference & Expo in San Francisco today.

 

In an exclusive partnership with Cingular, the nation's largest cellular phone carrier, Mr. Jobs brought his legendary product design sense to bear on one of the world's most ubiquitous products. He said Apple had set the goal of taking 1 percent of the world market for cell phones, or 10 million phones per year, by the end of 2008.

Underscoring the transformation of a quirky computer maker that during the past half decade has come to dominate the world of digital music, and signaling his ambition to become a force in new markets, Mr. Jobs announced that the Apple was dropping the "computer" from its name and would henceforth become Apple Inc.

Repeatedly during his two-hour presentation before an audience of journalists, analysts, Apple employees and customers, Mr. Jobs drew parallels between the Macintosh personal computer, which had a vast impact on the computer industry when it was introduced in 1984, and the new phone.

Noting that there are occasionally new products that change everything, Mr. Jobs noted, "Apple has been able to introduce a few of these into the world."

Apple's stock price rose more than 7 percent after the announcement, climbing over $92. Shares of two companies that make competing smart wireless devices, Palm Inc. and Research in Motion, fell more than 5 percent.

Touting the fact that the new iPhone is powered by the same core OS X operating system that runs Macintosh computers, Mr. Jobs showed a series of applications including e-mail, advanced voice mail, photo collections and visually appealing Web searching all on a device that will be priced beginning at $499. That model will have four gigabytes of storage, and an eight-gigabyte model will be available for $599.

The iPhone will offer five hours of operating time and 16 hours of audio playback, Mr. Jobs said. The phone will be compatible with Cingular's digital EDGE data network as well as Wi-Fi and Bluetooth networks.

Mr. Jobs defended the higher price of the new phone in a market where smartphone prices are rapidly plunging to $200 and below. He compared the iPhone, which has only one mechanical button on its surface, to smartphones from Motorola, Research In Motion and Palm. Rather than what he called "small plastic keyboards," the iPhone will have a display that becomes both the keyboard and control panel, morphing to suit the current application.

Regis McKenna, the veteran public relations specialist and corporate strategist who originally tutored Mr. Jobs in the art of high-tech marketing beginning in the late 1970s, said: "This compares favorably with the launch of the Macintosh. The price is high, but it will come down."

The new phone will not go on sale at Apple and Cingular stores in the United States until June of this year, Mr. Jobs said, noting that he had chosen to avoid early public disclosure on a Federal Communications Commission Web site.

The iPhone will be introduced in Europe during the fourth quarter and in Asia in 2008.The user interface of the iPhone rests heavily on a high-resolution touch screen that makes it possible to use a finger to control the phone. It also has several more subtle features, including sensors that track light and movement to prompt the phone to control screen brightness and physical orientation and other aspects of its operation. For example, when the phone is placed next to the user's face, the keyboard is automatically turned off.

One of the immediate questions that analysts and industry executives posed about Apple's new product was why the designers eschewed the higher-speed Cingular digital cellular 3-G network. Mr. Jobs said later models would support additional networking standards.

Apple chose to name the new phone iPhone despite the fact that Cisco Systems, the network and consumer wireless company, has recently introduced a Wi-Fi-based phone with the same name. Mr. Jobs had been negotiating with Cisco executives over the trademark in recent days. Both companies claim the name.

Tips for Protecting the Home Computer

By JOHN MARKOFF

Botnet programs and other malicious software largely take aim at PCs running the Microsoft Windows operating system, because Windows' ubiquity makes it fertile ground for network-based attacks.

Using a non-Windows-based PC may be one defense against these programs, known as malware; in addition, anti-malware programs and antivirus utilities for the PC are available from several vendors. Windows users should use the Windows Update feature.

Microsoft itself entered the computer-security business last year and now offers a free malware-removal tool for download from its Web site. The company says the program removes about two million pieces of malware each month, of which 200,000, or about 10 percent, are botnet infections.

Like Windows, Microsoft's Internet Explorer browser is also a large, convenient target for code-writing vandals. Alternative browsers, like Firefox and Opera, may insulate users. Microsoft's most recent browser release, Internet Explorer 7, is said to offer significantly improved defenses.

Adding software to your browser like Noscript, a plug-in utility, can limit the ability of remote programs to run potentially damaging programs on your PC.

Security experts also offer these tips:

¶Don't share your computer (on which you pay your bills) with your children (who download games).

¶Use a firewall program that warns you about outgoing connections that botnets make to communicate with control software.

¶Don't use the same password on more than one financial site.

¶Don't let your browser store your password for such sites.

¶Don't buy anything offered by a spammer.

¶Don't click if someone offers you something too good to be true. It is.

Attack of the Zombie Computers Is Growing Threat

By JOHN MARKOFF

In their persistent quest to breach the Internet's defenses, the bad guys are honing their weapons and increasing their firepower.

With growing sophistication, they are taking advantage of programs that secretly install themselves on thousands or even millions of personal computers, band these computers together into an unwitting army of zombies, and use the collective power of the dragooned network to commit Internet crimes.

These systems, called botnets, are being blamed for the huge spike in spam that bedeviled the Internet in recent months, as well as fraud and data theft.

Security researchers have been concerned about botnets for some time because they automate and amplify the effects of viruses and other malicious programs.

What is new is the vastly escalating scale of the problem — and the precision with which some of the programs can scan computers for specific information, like corporate and personal data, to drain money from online bank accounts and stock brokerages.

"It's the perfect crime, both low-risk and high-profit," said Gadi Evron, a computer security researcher for an Israeli-based firm, Beyond Security, who coordinates an international volunteer effort to fight botnets. "The war to make the Internet safe was lost long ago, and we need to figure out what to do now."

Last spring, a program was discovered at a foreign coast guard agency that systematically searched for documents that had shipping schedules, then forwarded them to an e-mail address in China, according to David Rand, chief technology officer of Trend Micro, a Tokyo-based computer security firm. He declined to identify the agency because it is a customer.

Although there is a wide range of estimates of the overall infection rate, the scale and the power of the botnet programs have clearly become immense. David Dagon, a Georgia Institute of Technology researcher who is a co-founder of Damballa, a start-up company focusing on controlling botnets, said the consensus among scientists is that botnet programs are present on about 11 percent of the more than 650 million computers attached to the Internet.

Plagues of viruses and other malicious programs have periodically swept through the Internet since 1988, when there were only 60,000 computers online. Each time, computer security managers and users have cleaned up the damage and patched holes in systems.

In recent years, however, such attacks have increasingly become endemic, forcing increasingly stringent security responses. And the emergence of botnets has alarmed not just computer security experts, but also specialists who created the early Internet infrastructure.

"It represents a threat but it's one that is hard to explain," said David J. Farber, a Carnegie Mellon computer scientist who was an Internet pioneer. "It's an insidious threat, and what worries me is that the scope of the problem is still not clear to most people." Referring to Windows computers, he added, "The popular machines are so easy to penetrate, and that's scary."

So far botnets have predominantly infected Windows-based computers, although there have been scattered reports of botnet-related attacks on computers running the Linux and Macintosh operating systems. The programs are often created by small groups of code writers in Eastern Europe and elsewhere and distributed in a variety of ways, including e-mail attachments and downloads by users who do not know they are getting something malicious. They can even be present in pirated software sold on online auction sites. Once installed on Internet-connected PCs, they can be controlled using a widely available communications system called Internet Relay Chat, or I.R.C.

ShadowServer, a voluntary organization of computer security experts that monitors botnet activity, is now tracking more than 400,000 infected machines and about 1,450 separate I.R.C. control systems, which are called Command & Control servers.

The financial danger can be seen in a technical report presented last summer by a security researcher who analyzed the information contained in a 200-megabyte file that he had intercepted. The file had been generated by a botnet that was systematically harvesting stolen information and then hiding it in a secret location where the data could be retrieved by the botnet master.

The data in the file had been collected during a 30-day period, according to Rick Wesson, chief executive of Support Intelligence, a San Francisco-based company that sells information on computer security threats to corporations and federal agencies. The data came from 793 infected computers and it generated 54,926 log-in credentials and 281 credit-card numbers. The stolen information affected 1,239 companies, he said, including 35 stock brokerages, 86 bank accounts, 174 e-commerce accounts and 245 e-mail accounts.

Sensor information collected by his company is now able to identify more than 250,000 new botnet infections daily, Mr. Wesson said.

"We are losing this war badly," he said. "Even the vendors understand that we are losing the war."

According to the annual intelligence report of MessageLabs, a New York-based computer security firm, more than 80 percent of all spam now originates from botnets. Last month, for the first time ever, a single Internet service provider generated more than one billion spam e-mail messages in a 24-hour period, according to a ranking system maintained by Trend Micro, the computer security firm. That indicated that machines of the service providers' customers had been woven into a giant network, with a single control point using them to pump out spam.

The extent of the botnet threat was underscored in recent months by the emergence of a version of the stealthy program that adds computers to the botnet. The recent version of the program, which security researchers are calling "rustock," infected several hundred thousand Internet-connected computers and then began generating vast quantities of spam e-mail messages as part of a "pump and dump" stock scheme.

The author of the program, who is active on Internet technical discussion groups and claims to live in Zimbabwe, has found a way to hide the infecting agent in such a way that it leaves none of the traditional digital fingerprints that have been used to detect such programs.

Moreover, although rustock is currently being used for distributing spam, it is a more general tool that can be used with many other forms of illegal Internet activity.

"It could be used for other types of malware as well," said Joe Stewart, a researcher at SecureWorks, an Atlanta-based computer security firm. "It's just a payload delivery system with extra stealth."

Last month Mr. Stewart tracked trading around a penny stock being touted in a spam campaign. The Diamant Art Corporation was trading for 8 cents on Dec. 15 when a series of small transactions involving 11,532,726 shares raised the price of the stock to 11 cents. After the close of business that day, a Friday, a botnet began spewing out millions of spam messages, he said.

On the following Monday, the stock went first to 19 cents per share and then ultimately to 25 cents a share. He estimated that if the spammer then sold the shares purchased at the peak on Monday he would realize a $20,000 profit. (By Dec. 20, it was down to 12 cents.)

Computer security experts warn that botnet programs are evolving faster than security firms can respond and have now come to represent a fundamental threat to the viability of the commercial Internet. The problem is being compounded, they say, because many Internet service providers are either ignoring or minimizing the problem.

"It's a huge scientific, policy, and ultimately social crisis, and no one is taking any responsibility for addressing it," said K. C. Claffy , a veteran Internet researcher at the San Diego Supercomputer Center.

The $6 billion computer security industry offers a growing array of products and services that are targeted at network operators, corporations and individual computer users. Yet the industry has a poor track record so far in combating the plague, according to computer security researchers.

"This is a little bit like airlines advertising how infrequently they crash into mountains," said Mr. Dagon, the Comic Sans MS Tech researcher.

The malicious software is continually being refined by "black hat" programmers to defeat software that detects the malicious programs by tracking digital fingerprints.

Some botnet-installed programs have been identified that exploit features of the Windows operating system, like the ability to recognize recently viewed documents. Botnet authors assume that any personal document that a computer owner has used recently will also be of interest to a data thief, Mr. Dagon said.

Serry Winkler, a sales representative in Denver, said that she had turned off the network-security software provided by her Internet service provider because it slowed performance to a crawl on her PC, which was running Windows 98. A few months ago four sheriff's deputies pounded on her apartment door to confiscate the PC, which they said was being used to order goods from Sears with a stolen credit card. The computer, it turned out, had been commandeered by an intruder who was using it remotely.

"I'm a middle-aged single woman living here for six years," she said. "Do I sound like a terrorist?"

She is now planning to buy a more up-to-date PC, she said.
