Internet phone company Skype is testing a new version of its cheap call service that supports high quality video conferencing for the first time.
Skype 4.0 beta can stream full screen, high resolution video calls over a standard broadband connection.
In the current version of the software, video chat is limited to a postage-stamp sized box in the corner of the screen.
Video calls already account for a quarter of all traffic on Skype.
The company’s product development manager Mike Bartlett said: “There’s now a video call button for every one of your contacts. We’ve tried to make it easier to get up and running.
“We’ve made the picture a lot bigger and you can now resize the image plus you can run an instant message conversation along side it really easily.”
New interface
But users must first connect to a friend and then hunt around for a tiny camera icon after the audio link has already been established.
The new software, which Skype calls a “major” update, treats video, text and audio conversations equally.
Other 4.0 features include a brand new user interface, automatic detection of hardware settings and simpler record-keeping functions.
It is designed to work with software from other manufacturers, allowing users to import contacts from services like Microsoft Outlook, Hotmail and Yahoo! Mail for the first time.
Tighter integration with the PayPal money transfer service should make it easier to send cash to friends, contacts and shops over the Skype network.
Making money
Skype, which is owned by the auction giant eBay, works over the standard internet instead of traditional phone lines, letting users make calls between computers for free.
Calls to other landlines and some mobile phones are charged at between 2 pence and 14 pence a minute.
Skype claims to have 309m registered members and 12m users at the busiest times of the day. But although it is the largest company of its type in the world, it has struggled to make money.
EBay recently said the business is worth $1.4bn less than the $2.6bn it paid for it in 2005.
According to some reports, it is thinking of selling Skype before the end of the year if it cannot find a way to integrate the technology into its main auction site.

News Corp.’s MySpace is set to release a major redesign next week, company representatives said late Thursday evening. The site doesn’t look that different; it’s still clearly MySpace. But a number of features have been revamped to improve user experience: namely, the homepage, navigation tools, profile editor, search features, and the MySpaceTV player.
A formal release is set to go out on Monday, and the first new features will show up on the site on Wednesday.
The redesign effort has been under way for more than six months, with the goals of appealing to a broader demographic and letting users interact with the site more (i.e. keeping them around), and has involved in-home studies for testing purposes.
The relaunch of the homepage proper has been kept somewhat under wraps, likely because a “major” advertiser is set to take over the site when it debuts. But MySpace has been liberal with the details of most of the other new improvements. They’re not particularly revolutionary, but should still do a thing or two to combat user experience complaints on the social network.
The MySpace profile editing tool, for example, has been modified so that HTML expertise is less of a prerequisite. A sidebar lets users browse through themes and alter them with a color palette, rather than hard-coding changes.
The MySpaceTV player, which technically competes with YouTube, has been improved to support high-definition video and improved full-screen mode as part of the Flash 9 release. The embeddable player now has internal search as well as a way to view the top MySpace videos; it’s still playing catch-up with the likes of YouTube, but it’s still a big improvement.
One of the most heavily altered sections of the new MySpace is search; now, MySpace members will navigate through a set of tabs to search personal profiles, music profiles, the entire MySpace site, videos on MySpaceTV, or the Web as a whole. The site has also worked with the Lucene open-source search engine project.
MySpace’s chief rival, Facebook, is also set to unveil a redesigned profile page in the near future; developers on its application platform are already testing it out. MySpace’s redesign does not appear to alter the experience for developers who are building on its OpenSocial-compatible platform.
MySpace additionally has a data portability project, “Data Availability,” on the way.

Most of today’s web sites and web applications are built using the JavaScript scripting language. Some may say that a trend towards the fine-tuning of JavaScript interpreters in modern browsers was just a matter of time since any such optimization translates into performance gains. Mozilla recently launched the browser speed race with Firefox 3, which delivers more speed than any other previous Firefox version. Apple answered with Safari 4, claiming the browser’s JavaScript engine has been accelerated by 53%. Welcome to the browser speed race.
Safari 4 has just been seeded to the developers at Apple’s developer conference. The manufacturer claims that the software has a 53% faster JavaScript engine than the preceding and current version 3.1 (based on the SunSpider JavaScript Performance test conducted on iMac with an Intel Core 2 Duo processor at 2.8 GHz, with 2 GB of RAM and running under Mac OS X Snow Leopard.) Although Firefox 3 RC3 was the first to deliver significant JavaScript performance improvement, Apple apparently is exceeding those gains with Safari 4.
Apple uses a new and improved JavaScript interpreter code-named SquirrelFish, which is provided on an open-source basis from the WebKit project, the same organization that makes the open-source engine used by Safari to render web pages. According to the WebKit project, the SquirrelFish engine is 1.6 times faster than the JavaScript engine in Safari 3.1.
SquirrelFish does its magic by turning JavaScript script into so-called bytecodes, an optimized code much more suitable for run-time execution than natural language-based JavaScript commands, which are longer and more complicated to interpret – and therefore are slower.
Why JavaScript performance matters
Most today’s web applications and web 2.0 sites rely on the JavaScript scripting language originally created by current Mozilla CTO Brendan Eich while he was employed by Netscape. JavaScript acts as glue that connects a user interface rendered in a web browser with a database and programming logic running in a web server. The browser’s JavaScript engine is solely responsible for interpreting and executing JavaScript commands embedded in HTML code. As a result, a browser’s JavaScript engine performance is directly related to the performance and responsiveness of a web application, contributing to an improved user experience.
The fact that many applications grow in size and become more bloated with each release means that a browser that can run web applications faster and make user interfaces more responsive on any computer is actually a big deal. You don’t have to have any specific market forecasting talent to predict that this trend may be impacting browser market shares: Speed can directly translate into more usability for most of us. Clearly, JavaScript handling is on its way to become a powerful weapon in the browser market.
SpiderMonkey, SquirrelFish, Tamarin and more
Mozilla was the first to introduce significant speed gains with Firefox 3 beta 5 (the final version is expected to ship by mid-June). Firefox has its Gecko engine to render web pages, which is generally considered to be slightly slower than Safari’s WebKit – which is largely responsible for the “fastest browser in the world” status Safari enjoys. Firefox’ JavaScript implementation is based on Mozilla’s own and decade old SpiderMonkey technology, which many considered to be the fastest JavaScript interpreter until SquirrelFish came out.
Although in beta, Firefox 3 scored with many reviewers who are praising the browser’s performance improvements, with WSJ’s Walt Mossberg declaring the browser a “winner.” But now that the SquirrelFish/Safari combination appears to be offsetting the speed gains in Firefox 3 and may set a new benchmark, we can expect more direct competition between Mozilla and Apple. Mozilla has plans to expand SpiderMonkey with Adobe’s JavaScript engine called Tamarin, included in Flash 9, which has a so-called “tracing” feature designed to enable faster code execution. However, the SunSpider JavaScript benchmark claims that SquirrelFish is at least 1.9 times faster than Tamarin.
Mozilla plans to wedge Tamarin into Firefox and match the API’s of both technologies “There are areas in which SpiderMonkey is faster than Tamarin and areas where it’s not. We’re looking to build hybrids that are best-of-breed for both worlds and we’re going to pull those into the Firefox release when ready,” Mozilla co-founder Mike Shaver recently said.
Can IE8 compete?
The big variable in this game is Microsoft’s Internet Explorer 8, currently in beta 1 phase. IE8 is expected to deliver speed gains in JavaScript performance as well. However, Microsoft is facing a tough task. The fact that the software giant is often criticized for delivering bloated and inefficient software certainly doesn’t help. In our tests, the first beta of IE8 shows no noticeable speed gains in running web applications.
Quite the opposite is the case, actually. Websites and web applications run noticeably slower than in IE7. The whole browsing experience generally appears to be less responsive. Of course, IE8 is in an early development stage and you can bet Microsoft is going to tweak its performance. The only problem is that the software giant will have to work to raise the stakes in the browser race. If IE8 under-delivers, the market could respond with further market share erosion for IE. It is evident now that JavaScript engine performance has become a key metric in the newest race for the title of fastest browser.
The battle ahead is nicely summed by Mozilla co-founder Mike Shaver who said the following: “They [Apple] have dropped SquirrelFish in now and got a big speed up there. We’ve got more coming on our side. You’ll see this leapfrog pattern over and over. We’re not going to let anybody slack on that and the other browser vendors need to keep up, too.”
According to Net Applications, Firefox 3 captured almost one fifth (18.41%) of the browser market in May, followed by Safari 3.1 which hit 6.25%. Microsoft’s Internet Explorer continues on its pace of a slow but steady decline, ending up at 73.75% in May. Microsoft has scheduled second beta of IE8 for an August release, with a generally expected final release in the fourth quarter of this year.
