The Apache Software Foundation Announces Apache Pivot 2.0

Open Source Platform for Building Installable Internet Applications Makes Building GUI Applications Even Easier

Forest Hill, MD – 19 January 2011 – The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache Pivot 2.0, the full-featured, Open Source platform for building installable Internet applications (IIAs). Apache Pivot provides a professional-grade foundation for easily building and deploying sophisticated and engaging GUI applications that can be downloaded and installed like traditional desktop or mobile applications.

Apache Pivot combines the enhanced productivity and usability features of a modern user interface toolkit with the power of Java or any other JVM-compatible language, such as JavaScript, Groovy, or Scala.

"With Pivot, developers use the languages, tools, and APIs they already know, thereby reducing technology sprawl and streamlining solution technology stacks," said Greg Brown, Vice President of Apache Pivot. "It's a truly open solution for creating visually rich, highly functional desktop or Web-based applications."

Apache Pivot is used in hundreds of applications across numerous industries, including retail, software, financial services, manufacturing, aerospace, and education, among others. Many of these applications have been developed for international use as well, as one of the key benefits of using Apache Pivot is ease of localization.

Apache Pivot 2.0 features a number of significant enhancements that include:

- Dynamic data binding – properties of target elements are automatically updated whenever a source value changes;

- Support for named styles – CSS-like style classes are supported, including both typed and untyped style selectors;

- Support for SVG images in addition to standard bitmap-based images (such as JPEG, PNG, or GIF)

- Overhauled TextArea component – includes word navigation. undo/redo, and improved cut/paste behavior;

- Additional color schemes optimized for a variety of popular desktop environments;

- Serializer events – applications can now be notified as structured content such as JSON, XML, or CSV is read from an input stream;

- Eclipse launcher – an Eclipse plugin helps simplify creating launch configurations for Pivot applications.


Oversight and Availability
Apache Pivot is available under the Apache Software License v2.0, and is overseen by a Project Management Committee (PMC), who guide its day-to-day operations, including community development and product releases.

Apache Pivot 2.0 downloads, documentation, and related resources are available at http://pivot.apache.org/.

The Apache Software Foundation Announces Apache Cassandra 0.7


Highly-scalable Open Source Distributed Database for Handling Large Amounts of Data is a Key Component in Cloud Computing

Forest Hill, MD – 11 January 2011 – The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced Apache Cassandra v0.7, the highly-scalable, second generation Open Source distributed database.

"Apache Cassandra is a key component in cloud computing and other applications that deal with massive amounts of data and high query volumes," said Jonathan Ellis, Vice President of Apache Cassandra. "It is particularly successful in powering large web sites with sharp growth rates."

Apache Cassandra is successfully deployed at organizations with active data sets and large server clusters, including Cisco, Cloudkick, Digg, Facebook, Rackspace, and Twitter. The largest Cassandra cluster to date contains over 400 machines.

"Running any large website is a constant race between scaling your user base and scaling your infrastructure to support it," said David King, Lead Developer at Reddit. "Our traffic more than tripled this year, and the transparent scalability afforded to us by Apache Cassandra is in large part what allowed us to do it on our limited resources. Cassandra v0.7 represents the real-life operations lessons learned from installations like ours and provides further features like column expiration that allow us to scale even more of our infrastructure."

Among the new features in Apache Cassandra v0.7 are:

- Secondary Indexes, an expressive, efficient way to query data through node-local storage on the client side;

- Large Row Support, up to two billion columns per row;

- Online Schema Changes – automated online schema changes from the client API allow adding and modifying object definitions without requiring a cluster restart.

Oversight and Availability
Apache Cassandra is available under the Apache Software License v2.0, and is overseen by a Project Management Committee (PMC), who guide its day-to-day operations, including community development and product releases.

Apache Cassandra v0.7 downloads, documentation, and related resources are available at http://cassandra.apache.org/.

The Apache Software Foundation Announces Apache OODT as a Top-Level Project

Open Source middleware for managing, unifying, and archiving data used in critical scientific applications, including NASA Jet Propulsion Laboratory, National Cancer Institute, and Children's Hospital Los Angeles Virtual Pediatric Intensive Care Unit

The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced that Apache OODT (Object-Oriented Data Technology) has graduated from the Apache Incubator to become a Top-Level Project (TLP), signifying that the Project's community and products have been well-governed under the ASF's meritocratic, consensus-driven process and principles.

Apache OODT is "middleware for metadata" (and vice versa), used for computer processing workflow, hardware and file management, information integration, and linking databases. The OODT architecture allows distributed computing and data resources to be searchable and utilized by any end user.

Originally developed in 1998 by Daniel Crichton at NASA's Jet Propulsion Laboratory to build a national framework for data sharing, OODT was quickly applied to other areas in physical science, medical research, and ground data systems. Early implementations include the National Cancer Institute’s Early Detection Research Network, as well as several programs at NASA, including the NASA Planetary Data System, SeaWINDS QuikSCAT project, the OCO/Atmospheric Carbon Observations from Space project, the joint NASA/DOD/NOAA NPOESS Preparatory Project, and the Soil Moisture Active Passive mission testbed. In addition, Apache OODT is also used in a number of research and technology tasks spanning astrophysics, radio astronomy, and climate change research. Apache OODT is also currently supporting research and data analysis within the pediatric intensive care domain in collaboration with Children's Hospital Los Angeles (CHLA) and its Laura P. and Leland K. Whittier Virtual Pediatric Intensive Care Unit (VPICU).

"OODT had been successfully operating within the JPL for years; the time had come to realize the benefits of open source in the broader, external community," said Chris Mattmann, Vice President of Apache OODT. "Bringing new developer talents is integral in enhancing the quality of the OODT code, and making OODT available as an Apache project was an ideal way to introduce new features and capabilities."

OODT is the first NASA-developed software package to become an ASF TLP (OODT was submitted to the Apache Incubator in January 2010). Projects incubating at the ASF benefit from hands-on mentoring from other Apache contributors, as well as the Foundation’s widely-emulated process, stewardship, outreach, support, and community events.

"The Apache Software Foundation has a long history of software innovation through collaboration -- the larger the pool of potential contributors, the more innovation we see," said Mattmann. "The Apache model and the Incubation process provided great guidance. We received solid mentoring, infrastructure, and development support from the Apache Software Foundation."

Oversight and Availability
All Apache products are released under the Apache Software Licence v2.0, and are overseen by a self-selected team of active contributors to the project. Upon a Project's maturity to a TLP, a Project Mangement Committee (PMC) is formed to guide its day-to-day operations, including community development and product releases.

"We are working on improvements to our initial, v0.1 Apache release," added Mattmann. "Our dozen-strong team of contributors are developing new components to more reliably and accurately extract metadata from science datasets."

Apache OODT downloads, documentation, and related resources are available at http://oodt.apache.org/.

About the Apache Incubator and Incubation Process
The Apache Incubator is the entry path for projects and codebases wishing to become part of the efforts at The Apache Software Foundation. All code donations from external organisations and existing external projects wishing to join the ASF enter through the Incubator to: 1) ensure all donations are in accordance with the ASF legal standards; and 2) develop new communities that adhere to our guiding principles. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Apache Subversion to WANdisco: +1 on the code contributions, -1 on the attitude.

In light of some recent press releases and blog posts from WANdisco ([1][2][3]), the Apache Subversion project would like to clarify that WANdisco, Inc participates in Subversion development under the same terms as any other organization.

Those wishing to verify this may prefer to use the project's public mailing lists and change logs as primary sources, rather than WANdisco's press releases.

Below are some of our specific concerns. We look forward to WANdisco's continued participation in improving Subversion, and emphasize that WANdisco's corporate statements do not reflect on our valued developers who happen to be employed there.

  • WANdisco CEO David Richards claims without evidence that bogus changes are being committed to the master tree. He wrote: "We ... believe it's unhelpful when certain unscrupulous committers decide to commit trivial changes in large files to simply get their stats up. That behavior has no place in any open source project; it's a bad form [sic] and wastes everyone's valuable time."

    We are unaware of any such behavior among the Subversion maintainers. Our repository logs are always open for public inspection, yet when asked to show evidence, Richards refused.

  • The first part of [1] would indicate to most readers that WANdisco was involved in the creation of Subversion; only if the reader were to persist for another six paragraphs would they finally encounter a disclaimer to the contrary. [3] has similar problems.

    WANdisco was not involved in the creation of Subversion. The Subversion open source project was started in 2000 by CollabNet, Inc. WANdisco's involvement started in 2008, when it began employing Subversion committers, all of whom had prior history with the project. Subversion became part of the Apache Software Foundation in 2009. (CollabNet continues to participate in Subversion development to this day, on the same terms as all the other individuals and companies who undertake or fund development work.)

  • The Subversion development team is already working towards the enhancements that WANdisco inexplicably portrays ([2], [3]) as bold, controversial steps that must be pushed through in the face of (conveniently unnamed) opposition. WANdisco participates in Subversion development along with many parties, and the Subversion project has always welcomed WANdisco's contributions. However, WANdisco alleges that some entities want to impede technical enhancements; at the same time, WANdisco also implies that it is the corporate leader of the project.

    Neither is true. Since WANdisco does not cite any sources for their specific claims, we cannot explain them. However, a bedrock condition of participation in Apache Subversion is that an individual contributor can have discussions, submit patches, review patches, and so forth, but that companies do not have a formal role. Instead, companies get involved by funding individuals to work on the project. WANdisco's false implication that it is in some kind of steering position in Subversion development discredits the efforts of other contributors and companies.

In conclusion, we reiterate that we welcome WANdisco's involvement in Subversion, and failure on WANdisco's part to address the above concerns will have no effect on the acceptance of technical work funded by WANdisco. We simply felt it necessary to clarify WANdisco's role in Apache Subversion, for the benefit of our users and potential contributors.
