Citrix completed its $500 million acquisition of XenSource, the primary sponsor of the open-source Xen virtualization software, the company said Monday at its iForum conference in Las Vegas.

XenSource will become the core of the company's new virtualization and management division, and XenSource Chief Executive Peter Levine will report directly to Citrix CEO Mark Templeton. Xen co-founder Ian Pratt will continue to lead the Xen project and now is a Citrix employee, the company said.

Xen, like competing virtualization packages from companies including VMware, SWsoft, Qumranet and Microsoft, lets a single computer run multiple operating systems simultaneously. The idea … Read more

I've been hearing more and more that proprietary companies are fighting back against open-source companies by giving away their software. "We can compete with free!" they chortle as they discount their license fees to zero, occasionally winning deals (with customers who don't yet fully understand that open source is far more than price tag).

But with every deal they win on these terms, they lose. Their cost structure can't support giving away million-dollar deals that cost (literally, at times) a million dollars to close. Talking with a friend at Oracle, he tells me they expend upwards of 18 months and 100 or so people working on their million-dollar deals.

In other words, they spend money like crazy so that they can win the deal and hold onto that maintenance revenue.… Read more

Today bluepulse, a free mobile social network, announced a platform shift that will give smartphone users access to the free service for the first time. Bluepulse is now Webware.

Until now, the strictly-mobile social network installed on JAD and JAR downloads to Java and Symbian cell phones, but wouldn't run on smartphones like Pocket PCs or Palm Treos. Migrating to a wholly Web-based app opens the door for smartphone users to take advantage of the service's instant messaging and social discovery mash-up.

In addition to making the switch to Web, bluepulse also adds an all-in-one message in-box and … Read more

Digby has partnered with well-known retailers like Barnes & Noble and Fossil to create a downloadable shopping app that lets you purchase goods from your (RIM 4.1 or above) BlackBerry smartphone.

Digby has done a good job minimizing typing and fast-tracking purchases with select retail partners. Simply scroll through the brand list, clicking deeper within the stripped-down interface to see items and special deals. You can set the alert function to nag you to buy a gift before an important occasion. You'll have to do much of that buying on faith, though--there's no built-in functionality to preview an item or research product ratings for items, at least none that I perused.

When the purchase is nigh, enter your locally-stored password and Digby will do the rest, passing the transaction along to the vendor to process. Credit card information is password protected and stored, encrypted, on the device.… Read more

Carbon counting, it seems, is a growth business.

Carbonetworks, from Victoria, British Columbia, has developed software that gives companies a way to make financial decisions around their carbon emissions. It's one of several organizations sprouting up and looking to build a business or derive revenue from regulatory limits on carbon.

Although North America does not yet have regulations that cap greenhouse gases like carbon dioxide, companies are already keeping track of their emissions, said CEO Michael Meehan, who started Carbonetworks in early 2006.

Even after doing an inventory, though, companies don't have a unified way of managing that … Read more

The Marble of Doom is a cute site created by some folks who clearly have a good sense of humor about waiting for their computer to finish processing. It's Mac-centric, and aimed to track all the time you've lost due to the Mac's version of the hourglass, also known as the "marble of doom" and "spinning beach ball of death." Whenever this happens, you just have to sit there and wait it out, leading to a somewhat inevitable destruction of any productivity.

The site tracks this time, and sorts it out by the … Read more

SAN FRANCISCO--One area where Sun Microsystems' Java caught on was in mobile phones, but a leader of the project is working to eventually replace the mobile-specific version of the software.

Java Standard Edition (SE), geared for desktop computers, will gradually supplant Java Micro Edition (ME) as technology improvements let more computing power be packed into smaller devices, said James Gosling, the Sun vice president often called the father of Java.

"We're trying to converge everything to the Java SE specification. Cell phones and TV set-top boxes are growing up," Gosling said at a Java media event here … Read more

What do you get when you cross a Firefox with a chameleon?

An open-source Web browser whose user interface is adapted to the look of the operating system it's running on. One change planned for the upcoming Firefox version 3, code-named Gran Paradiso, is this more native appearance.

"The Web browser is an incredibly central piece of the user's operating system, and we don't want the user's initial reaction to be that they have modified their computer to add some type of strange, foreign application," said Mozilla interface designer Alex Faaborg in a blog posting last week. &… Read more

Open-source software start-up Cleversafe has a new twist on an ages-old warning not to put all your eggs in one basket.

If it were up to the Chicago-based company, you'd protect your data by putting slices of your eggs in multiple baskets scattered across the globe.

In the earlier version of the company's software, you could reconstruct your entire egg collection even if five of eleven baskets were destroyed in earthquakes, swamped by tsunamis, consumed in an overheated data center inferno or otherwise lost. A new version released Tuesday, though, lets users choose their own egg slice and … Read more
