The Web development frameworks Rails and Merb have decided to end their rivalry and join forces in a single project, they said last week.

Palamida, a vendor that sells software and services around open-source software security and legal compliance, has named 25 open-source projects companies should not hesitate to use.

A recently-approved technology standard should help software developers to tap the latent processing power of graphics chips and transform regular computers into veritable supercomputers -- at least for certain applications. Poised to take advantage of the technology first is Apple.

Opera Software Thursday launched a preview of its next browser, Opera 10, that aces the Acid3 Web standards test, a mark that most browser makers have pursued without success.

Microsoft on Wednesday unveiled a free plug-in for Firefox to translate Open XML documents, an update to its document translator and a toolkit for Java developers that was built under the umbrella of its Document Interoperability Initiative.

"It is enough that the people know there was an election. The people who cast the votes decide nothing. The people who count the votes decide everything." -- Joseph Stalin

Late last year, Google announced that it would give US$10 million worth in prizes to software development companies to develop innovative and useful applications for their open source mobile Android platform.

Developers who adopt the Google App Engine for their cloud computing platform today may fear data lock-in, since the only way to import or export data is using a Python-based API. Google is working on a tool to improve data exchange to improve data portability.

Once the domain of monolithic, multimillion-dollar supercomputers from Cray and IBM, HPC (high-performance computing) is now firmly within reach of today's enterprise, thanks to the affordable computing power of clustered standards-based Linux and Microsoft servers running commodity Intel Xeon and AMD Opteron processors. Many early movers are in fact already capitalizing on in-house HPC, assembling and managing small-scale clusters on their own.

When Scott Thompson left Visa to take the CTO role at PayPal in 2005, the Web company's data centre surprised him. "Wait a minute," he recalls saying, "they run a payment system on Linux?"

Jorge Villagran supervises one of the most important and sensitive projects in Guatemalan history: preserving and digitizing a massive trove of documents from the National Police files so that the country can gather evidence about human-rights abuses and bury the last vestiges of a brutal civil war.

Repeated efforts at Nationwide Mutual Insurance to try Linux on the mainframe faced opposition, some of it from IT employees worried that a mainframe-server consolidation would be a threat to their jobs. But their resistance offered James Vincent, a mainframe systems engineering consultant at Nationwide, a lesson that he put into use after the project was approved.

The city of Munich got more media attention than respect after it decided on a migration to Linux and open source software on the desktop. After a careful and deliberately open movement towards deciding its IT future, Munich was slammed in the media, then became a target for Microsoft negotiators and a project at risk from a proposed European move to U.S.-style software patents.

In one of the final scenes of the movie, "Charlie Wilson's War," the story of America's part in Afghanistan's victory over the Soviet Union, Congressman Wilson is shown asking for more funding to rebuild Afghanistan, a request that is denied.

Paul Cormier is Red Hat's executive VP and head of Red Hat products and technologies divisions. His experienced thumb is firmly planted in many Red Hat pies; including engineering, product management and product marketing. The company credits the introduction of Red Hat Enterprise Linux (RHEL) to Cormier's leadership and experience in enterprise technology. Cormier has returned Down Under on another visit to Red Hat's research and development team in Brisbane, and took some time out to chat with Computerworld about the anticipated boom in virtualisation, cloud computing, Microsoft's open source initiatives, CentOS, JBoss Application Server 5.0, how open source software can aid the current economic downturn, and of course, the growing role of Linux and RHEL in the enterprise.

While perhaps best known as a major social networking site in the Web 2.0 vein, Facebook is becoming a popular place to interface with potential customers, similar to what companies such as Scribe and iLike have done. Facebook also is being viewed as a place for enterprise collaboration, with Serena Software leveraging the site for this purpose. To get perspective on Facebook, InfoWorld Editor at Large Paul Krill recently spoke with Aditya Agarwal, Facebook director of engineering. Agarwal formerly worked in the Oracle server technologies division.

Computerworld is undertaking a series of investigations into the most widely-used programming languages. Previously we spoke to Alfred v. Aho of AWK fame, and in this article we chat to Chet Ramey about his experience maintaining Bash.

The Internet engineering community will be eating its own dog food tonight. For one hour, the 1,250 network experts at the Internet Engineering Task Force meeting will be able to access the Internet only through IPv6. The IETF created IPv6 in the mid-1990s, but this upgrade to the Internet's main communications protocol has not yet been widely deployed -- even by the technology's biggest proponents here. Network World National Correspondent Carolyn Duffy Marsan talked with IETF Chair Russ Housley about the group's IPv6 experiment, why the transition to IPv6 is taking so long, and whether the IETF leadership is starting to panic about IPv4 addresses running out. Here are excerpts from their conversation:

The question of why so many Google products are classified "beta" -- and classified thusly for so long -- has knocked around the tech press for some time. However, no one really seemed to know the answer, at least no one outside of Google.

I love lampooning the FOSS community. These self-righteous cyber-hippies are almost always good for a blog entry or two per month. And because many of them can't resist airing their own community's dirty laundry, I have no shortage of story ideas to choose from.

I'm continually amazed at how the premier Web properties are willing to share what they are doing. We get to peek behind the curtain routinely. Google and Yahoo both have good lab pages, but there's some seriously experimental stuff on the Mozilla labs page. Here's what they're up to.

For a technology that has been in stable release since May 22, 2000, PHP 4 has finally reached the end of its official life. With the release of PHP 4.4.9, official support has ended and the final security patch for the platform issued.

The obvious thought came to me while writing last week's column, that about the only folk (other than the deluded and amoral management of the SCO Group) that want the SCO Group effort attacking Linux and other open source initiatives to succeed is Microsoft. So I decided to explore that side in this follow-up column, but a bit of reading led me to the conclusion that things are not as simple as they appear.

Need to do forms development sans Access or Filemaker? Want rapid Web apps without Ruby on Rails? Want a rich Internet interface and abhor Ajax? Need PostgreSQL development, but don't do PHP? Just want a Java application without the, well, Java? Why not check out the once:radix Web-based RAD environment from once:technologies. And, by the way, did I mention it's open source?

Are you looking for a Windows alternative for serious office work? Many people are starting to wonder about their non-Microsoft operating system options, especially given Windows Vista's hefty hardware demands, upgrade costs and license restrictions. We've already examined using Mac OS X in the workplace; now, I take a hard look at Linux by using an enterprise distribution exclusively at work. I'm not simply playing with a test machine; I've been using Novell's SUSE Linux Enterprise Desktop 10+ day in, day out to do my job as Computerworld's online managing editor in the U.S.

As open source software pushes its way further into the enterprise, a new set of risks has arisen regarding IP (intellectual property). The problem is that developers happily borrow code from various projects to save themselves from having to reinvent it. This help is all well and good as long as the resulting software complies with the licenses of the donor projects. The problem managers have is that they cannot know what parts of their code base comes from open source projects. A code snippet reused from a newsgroup posting could actually have come from a copyrighted open source project. And its use could legally require the company to open source its entire product. If the company is an ISV, it might even be faced with being required to offer its product at no cost.

Dutch Internet company Chinglish promises to break down the communication barrier between Chinese and English speakers with its free, bilingual e-mail service. But the service falls short, plagued by translation errors that are common to all machine translators.

Earlier this month, Apple Computer CEO Steve Jobs unveiled new hardware at the company's Worldwide Developers Conference (WWDC) -- and more importantly, offered an early look at Mac OS X 10.5, code-named Leopard. Although Jobs noted that some features of the company's next operating system, which is due out sometime early in 2007, would remain secret for now, he did take developers through a tour of some of the software's new features.
