In a Linux system, files, blocks, directories, sockets and other items are referred by corresponding file descriptors. If your system is reporting errors that the file descriptor is bad, one of possible causes is that file system is corrupt and thus, you require restoring from backup. But if backup is not valid enough to restore complete information, you need to use advanced Linux Data Recovery applications. As an instance, you might encounter the below error message with your Linux based system: “Bad file descriptor” You might receive this error while trying to access a file or while trying to boot the system. Cause Possible reasons for the ‘Bad file descriptor’ error to occur are: Linux systems use a special file, called /dev/null (also called the null device). This file removes all the data that is written to it after reporting that the write process has succes... (more)

Canoo Releases Free Open Source XML Tool for Java RIA Development

Canoo has announced the release of ULC XML, a tool that allows developers to create UltraLightClient user interfaces from XML files. ULC XML is a free and open-source tool for Canoo’s Java RIA library. It is available for download at the ULC XML project site (https://ulcxml.dev.java.net/) at Java.net. ULC XML is an UI generator for UltraLightClient applications. The XML file is parsed at runtime and rendered into Java objects. ULC XML is similar to the solution offered by the open source project SwiXml: Java classes are mapped to element names; property names translate into attribute names. Developers familiar with SwiXml have little effort learning how to use ULC XML. The Canoo tool offers a Rich Internet Application (RIA) option for SwiXml/Swing developers. The download package includes free samples such as the ULC XML version of the ULC OnlineShop demo. ULC... (more)

IBM Reads Orwell’s “1984,” Tries Rewriting History

Opening Keynote at Cloud Expo Once the news got out that it had welched on its 2005 patent pledge to the open source community and had threatened TurboHercules (TH) with patent infringement, IBM had to come up with some cover story or another to contain the fallout. So it switched places with many of its observers and turned conspiracy theorist, accusing Turbo Hercules of guilt by association. Besides calling TurboHercules a couple of dirty names - a stock response to any threats to its monopoly in order to scare away its rivals' customers... And besides claiming that it didn't really flat out actually and in fact accuse TH of infringing - "we did not make any explicit assertions or claims," it said, "that TurboHercules had violated" that list of 173 patents and patent applications we sent them under the assertion that "IBM believes [this IP] will be infringed by an...

Google Fires First Shot in Brewing Codec War

Google fired a shot across Apple's bow Wednesday and considering the way things have been going Apple will probably seek to return fire in the not-too-distant future with an armor-piercing lawsuit. The latest fray started when Google got up at the Google I/O developers conference - like it was widely expected to do - and open sourced VP8, the video codec it got when it acquired On2 Technologies, the video compression house, in February for about $125 million. VP8 will try to displace H.264, the proprietary codec that Apple and Microsoft are invested in. VP8 is now part of a thing called the WebM project, which also includes the open source Ogg Vorbis audio format, and a container format based on a subset of the open source Matroska multimedia container. Needless to say, WebM is royalty-free and already has the support of the majority of the browser community: the Mo... (more)

BlogMobs – The Attack of the Fifth Estate

The events in Egypt over the past few days made me think about an article I was compelled to write back in late June 2006. It pondered the question, “Can any traditionally organized government withstand the ideological forces of a technologically empowered proletariat?” Call them blogmobs, txtmobs, tweetmobs or simply publishers, everyone in Egypt has a voice – and no matter how the government tries to silence them, in the Information Age, information will find a way. Here’s what I’ve been thinking about: Throughout history, the Estates of the Realm have come under various attacks. In the past, the asymmetry of wealth usually struck the decisive winning blow for the first or second estate, and all was set right with the world. Truth be told, the fourth estate (the press) has been under the complete control of the first (clergy) and second (nobility) estates throughout... (more)

Flashback: Investing in 'Professional Open Source' - Exclusive 2004 Interview with David Skok, Matrix Partners

April: Exclusive Interview with Dale Fuller This past February David Skok's new VC firm - Matrix Partners - orchestrated, with Accel, a $10 million investment in JBoss, Inc. This first round of funding in an open source company was a bold play, but then David Skok, famous in the Java arena as the founder of SilverStream Software - acquired by Novell in 2002 - is no stranger to bold moves. The first question then, naturally enough, is to ask Skok whether this investment is somehow a contradiction, or whether there is indeed money to be made from open source? "We think that there's definitely money to be made," Skok says without hesitation. "Red Hat's a clear example," he adds. "They're now profitable on around a $100m annual revenue run-rate. And we're still in the early days of the open source movement."   Curious about the business model he sees underlying OSS, I ... (more)

AJAX and Mozilla XUL with JavaServer Faces

In our previous JDJ article - Rich Internet Components with JavaServer Faces - we discussed how JavaServer Faces can fulfill new presentation requirements without sacrificing application developer productivity building Rich Internet Applications (RIA). We discussed how JSF component writers can utilize technologies, such as AJAX and Mozilla XUL, to provide application developers with rich, interactive and reusable components. In order to use AJAX and Mozilla XUL with JSF, component writers have to make sure to provide any resource files need by these technologies, such as images, style sheets, or scripts. The standard approach to providing resource files for a JSF component library is to serve them directly out of the web application root file system. These resources are usually packaged in an archive (such as a ZIP file), and shipped separately from the JSF componen... (more)

Open Source and the Flash Platform: What Should Adobe Do Next?

Open source must in some way present itself as a bit of a dichotomy to Adobe, now that it has acquired Macromedia. It is generally accepted that open source solutions foster innovation and adoption. However, with an open file format and a free player, is it possible that some projects could eventually challenge Flash's own role by creating competing tools? Jim Phelan writes: In a major repositioning effort in June of 2005, Macromedia - now Adobe - unveiled the "Flash Platform." The conception of Flash, the company had decided, needed to change: Flash had evolved from a tool for designers to an interoperating set of technologies appropriate for web application development. The time had come to abandon Flash's winsome singularity and start talking in terms of solutions rather than products. The OSFlash Initiative Around the same time, a group of developers was working t... (more)

Government IT Expo: eGov and Open Standards

When President Obama appointed his new federal CIO, Vivek Kundra, last week, Kundra announced ambitious plans to "democratize" federal government data by making it accessible in open formats and in data feeds. His plan calls for the creation of a single point of access to all public federal information. The idea is to enable the data to be accessed by developers whose applications will open up federal data to the sunlight of millions of citizens by encouraging them to scrutinize how the Recovery Act's dollars will be spent. As chief technology officer for the District of Columbia, Kundra raised the bar by making government data more readily accessible to its residents, leveraging pre-existing Web 2.0 technologies like Facebook and YouTube. Federal agencies are now banding together to plan for how they are going to provide this information in an open, standardized ma... (more)
