The first Firefox 3.1 beta has been made available for download, bringing with it a number of cool new features. However, possibly the coolest of those features, the lightning-fast TraceMonkey JavaScript engine, is disabled by default. Fortunately, it’s a quick fix to turn it on:

“To activate it, type “about:config” into the Smart Bar, then type “javascript.options.jit.content” into the filter. Double-click on the preference listed to change the boolean setting from “false” to “true.” Close the window and you should notice an immediate improvement to the JavaScript rendering speed.”

He used the SunSpider JavaScript Benchmark test to demonstrate the improvements in the new engine, which completed the test in 2788 milliseconds, compared to 5447 ms for Firefox 3.0.3. Always the skeptics, we tried the benchmark ourselves, and witnessed an even more dramatic improvement.  For us, speed more than doubled, from 4725 ms to 2227 ms.

So if you’re trying out the 3.1 beta, enable the TraceMonkey engine and see what it can do for you. Share your experiences after the jump.

Let a 404 error be an opportunity for you not the death knell to a visit to your site.

How often have you mistyped a file name in a web address? Have you ever clicked on a search result listing link to a dead page?

How many times did this result in the frustratingly uninformative ‘404 - page not found’ thrown up by search engines or, worse, by ISPs flooding your screen with irrelevant ads? What do you? Try again or just go elsewhere? I’d put money on it being the latter!

Just remember how you feel when this happens to you and you’ll understand how important t is for you to make sure this doesn’t happen to your visitors.

RSS wears many a hats - rich site summary, really simple syndication- RSS or even Resource Description Framework (RDF).

RSS is basically a lighter XML format designed for sharing Web content. As it is one of the simplest uses of XML, RSS has become widely distributed. The RSS file can include a logo, a site link, an input box, and multiple news items. Each news item consists of a URL, a title, and a summary.

Because the data is in XML, and not a display language like HTML, RSS information can be flowed into a large number of devices. In addition to being used to create news summary web pages, RSS can be fed into stand-alone news browsers or headline viewers, PDAs, cell phones, email ticklers and even voice updates.

RSS files are created by content publishers and then delivered to people who have subscribed to that feed using a “feed reader” application also called a news aggregator. The feed reader program checks with the originator of the content regularly and if it finds any new content available from a particular site, downloads the information about it, called metadata, into the application automatically.
