A web browser understands data transfer protocols such as http, ftp, file and the like. It picks up the protocol component from the URL and then takes the next step that depends on the identified protocol. For example, if you enter the URL http://www.hinduonnet.com, the browser identifies the data transfer protocol as `http' and proceeds to contact the web server for collecting the relevant web page. Likewise, when you type the URL file://c: into its address box, the browser displays the local files from the `C' drive.
Another bookmarklet repository worth visiting is the Jesse's Bookmarklets Site (http://www.squarefree.com/bookmarklets/), which also hosts innumerable free bookmarklets.
The site features versatile bookmarklets which deal with a range of subjects that include `Link Bookmarklets' (tools for manipulating the URLs on the current web page), `Text and Data Bookmarklets' (bookmarklets that allow you to view the text of a web page in different ways) and `Web Development Bookmarklets' (that lets you debug a web page). Another site worth visiting for bookmarklets is Favelets (http://tantek.com/favelets/).
Apart from the repositories mentioned above, bookmarklets created by specific services are also in place. For example, many of you may be users of the popular web-based newsaggregator service Bloglines (http://www.bloglines.com) that can be used to read several newsfeeds from various sites on a single web page. To subscribe to an RSS feed with this service, normally you need to go through such steps as invoking the browser, accessing the `Bloglines' site and moving on to the subscription page. But, if you use the subscription bookmarklet, `Subscribe with Bloglines' provided by the service (http://www.bloglines.com/help/easysub), you can directly subscribe from any site with a single mouse click, while on your favourite news site, just click on the 'Subscribe' bookmarklet.
Crimson text editor
Anyone who has ever attempted to use the Windows editor, Notepad, to create such specialised text files as HTML, Java and PERL would know the limitations of this program. For an alternative text editor, have a look at the free, feature-packed text editor, Crimson.
This tool has features such as the facility to edit multiple files, spell checker, tool to record key strokes that can be played back using the `Replay Macro' button and so on. Another highlight of this editor is the built in calculator that can evaluate simple mathematical expressions. For more details: http://www. crimsoneditor.com/
Bloogz: A blog search engine
For many netizens, blogs have become one of the major on-line sources for keeping up-to-date with the latest information on any subject. But, as tens of hundreds of blogs are available on the Net, locating the ones that are relevant to an information seeker becomes a little difficult task.
One solution to get around this blog overload is to use a search service that tracks blogs. Bloogz (http://www.bloogz.com/) is one such search service for locating appropriate weblogs.
