Virtual Iron, a start-up trying to commercialize the open-source Xen virtualization software, has just gotten a new chief executive, and he wants to grab some of the attention lavished on rivals in the suddenly high-profile market.

The new CEO is Ed Walsh, who led Avamar Technologies, a company focusing on economizing storage by reducing duplicative data, which EMC acquired in 2004. John Thibault, who was named Virtual Iron's CEO in 2005, will remain executive chairman of the 73-employee Lowell, Mass.-based company, Virtual Iron plans to announce Monday.

Virtual Iron has been in the virtualization business for three years, … Read more

A month ago, Network Appliance sued Sun Microsystems, alleging the server and software company's ZFS file system infringes seven NetApp patents. Sun on Thursday fired back with a suit that claims NetApp violates 12 of Sun's.

Sun's suit also argues that NetApp's patents are invalid and that it doesn't infringe them anyway. And it requests an injunction prohibiting the company from selling any products that infringe Sun's patents.

Patent suits are often expensive and acrimonious proceedings, and they're particularly unpleasant when fought among Silicon Valley rivals who often share mutual customers and sometimes … Read more

A day after Sun Microsystems Chief Executive Jonathan Schwartz said his company will sue to have Network Appliances' file-server products removed from the market, NetApp's founder Dave Hitz brushed off the threat and took issue with Schwartz's open-source reasoning.

"This sounds like Sun's broad threats when they sued Azul, but in the end, Sun didn't put Azul out of business or even stop them from shipping products. I'm quite confident that two years from now--or however long it takes this suit to reach court--NetApp will be doing just fine," Hitz said in a blog posting … Read more

The SCO Group, working to emerge from Chapter 11 bankruptcy protection, hopes to sell its Unix assets to York Capital Management for up to $36 million, the company said this week in regulatory and bankruptcy court filings.

Through the deal, York would provide SCO with $10 million in cash; up to $10 million in credit to fund its Linux-related legal fight and to get 20 percent of revenue from that action; $10 million for a 20 percent stake in the company; and $6 million to license the Hipcheck products from SCO's Me mobile device software effort and to share … Read more

Updated at 2:31 p.m. PDT: Sun Microsystems plans to countersue Network Appliance later this week, Chief Executive Jonathan Schwartz said Wednesday, a suit that will include a request to remove the company's products from the market.

Schwartz said on his blog that he has "no interest whatever in suing them" and therefore "reached out" to Chief Executive Dan Warmenhoven. But, he said, NetApp's demands--that Sun "retract" its ZFS file system from open-source community and restrict its use to computing and not storage devices--can't be met.

Consequently, "Later this … Read more

Unfettered sharing is one of the hallmarks and touted virtues of open-source programming, but even companies closely allied to the movement can grow uncomfortable with such liberal principles.

Case in point: Palamida and Black Duck Software, two rivals that offer software and services to help companies ensure open-source and proprietary software aren't inappropriately intermixing.

On Monday, Black Duck announced its Open Source License Resource Center, described as "an online guide of particular interest to companies developing or deploying software that includes code governed by version three of the GNU General Public License (GPL) or Lesser General Public License (… Read more

Mozilla, the group behind the open-source Firefox Web browser, disclosed its 2006 revenue Monday night: $66,840,850.

That's a 26 percent bump up from the $52.9 million that Mozilla garnered in 2005. And with 2006 expenses slicing off only $19.8 million, Mozilla has a tidy sum left at its disposal, even if it's no Microsoft.

"The highlight is that Mozilla remains financially healthy: we're able to hire more people, build more products, help other projects, and bring more possibilities for participation in the Internet to millions of people," foundation Chairman Mitchell Baker said in a blog posting. … Read more

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

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
