Ellison on the prolonged investigation of the European Commision
The European Commission’s prolonged investigation of Oracle’s proposed acquisition of Sun, which isn’t expected to finish much before the agency’s mid-January deadline, is costing Sun $100 million a month in revenues, according to Oracle CEO Larry Ellison.
Ellison, who was interviewed on-stage after a Churchill Club dinner Monday evening by former Sun president and COO Ed Zander of all people, told the crowd, “The longer this takes, the more money Sun is going to lose, and that’s not good for anybody. We want to get this done to save as many jobs as possible.”continue to article

Oracle Acquires BEA Systems for $8.5 Billion
Oracle Corporation (NASDAQ: ORCL) and BEA Systems (NASDAQ: BEAS) announced today they have entered into a definitive agreement under which Oracle will acquire all outstanding shares of BEA for $19.375 per share in cash. The offer is valued at approximately $8.5 billion, or $7.2 billion net of BEA's cash on hand of $1.3 billion. "We expect this deal to be accretive to Oracle's earnings by at least 1-2 cents on a non-GAAP basis in its first full year after closing," said Oracle President and Chief Financial Officer Safra Catz.
"The addition of BEA products and technology will significantly enhance and extend Oracle's Fusion middleware software suite," said Oracle CEO Larry Ellison. "Oracle Fusion middleware has an open "hot-pluggable" architecture that allows customers the option of coupling BEA's WebLogic Java Server to virtually all the components of the Fusion software suite. That's just one example of how customers can choose among Oracle and BEA middleware products, knowing that those products will gracefully interoperate and be supported for years to come."

Support the Free Software Foundation
Dear free software supporter,
At the 2007 annual Associate Members meeting held in March at MIT in Cambridge, the FSF board and staff gathered with members from around the world to discuss our activities and the tremendous successes we have had together in the past year. We fought Digital Restrictions Management through our DefectiveByDesign.org campaign, released version 3 of the GNU General Public License to help neutralize anti-free-software laws like the Digital Millennium Copyright Act and defend against Microsoft's attempts to make free software proprietary through patent promises, released the GNU Affero GPL to support developers building network server software, supported fully free software distributions like gNewSense, backed high-priority software development projects like the free Flash player Gnash, and saw the continued success of our campaign to lift the "Java trap" with Sun's ongoing release of the Java platform under the GPL. Finally, following on from our discussion at the beginning of 2007 with major manufacturers and our release of the white paper, "Hardware Free From Restrictions," general-purpose computers are now available from major retailers with free software preloaded.

Ubuntu Home Server Edition Project
Ubuntu Home Server Edition has been established to facilitate a new Home Server Edition of Ubuntu.
The idea of a Home Server Edition of Ubuntu was recently outlined in this thread on the official Ubuntu forums:
Ubuntu is a leading free operating system for use on personal computer and servers: Ubuntu.com
The UHS project is community driven. It is not (yet) an official Ubuntu project.
Goals:
Ubuntu Home Server (UHS) will be an edition of the Ubuntu operating system which allows users to administer their home network. With Ubuntu Home Server you will be able to store all your music, songs and pictures in one central location, to access your files over the internet and to backup all the computers in your house.
The goal is to have a working release available with the upcoming Gutsy Gibbon release of Ubuntu (or perhaps Gutsy+1 at the latest).
Status
The project was recently launched. Presently the specifications are under heavy development and work on several components has begun.

New elements in HTML 5 - Structure and Semantics

Hypertext Markup Language (HTML) 5 introduces new elements to HTML for the first time since the last millennium. New structural elements include
Development of Hypertext Markup Language (HTML) stopped in 1999 with HTML 4. The World Wide Web Consortium (W3C) focused its efforts on changing the underlying syntax of HTML from Standard Generalized Markup Language (SGML) to Extensible Markup Language (XML), as well as completely new markup languages like Scalable Vector Graphics (SVG), XForms, and MathML. Browser vendors focused on browser features like tabs and Rich Site Summary (RSS) readers. Web designers started learning Cascading Style Sheets (CSS) and the JavaScript™ language to build their own applications on top of the existing frameworks using Asynchronous JavaScript + XML (Ajax). But HTML itself grew hardly at all in the next eight years.

Hypertext Markup Language (HTML) 5 introduces new elements to HTML for the first time since the last millennium. New structural elements include
aside, figure, and section. New inline elements include time, meter, and progress. New embedding elements include video and audio. New interactive elements include details, datagrid, and command.Development of Hypertext Markup Language (HTML) stopped in 1999 with HTML 4.

Eventually, the two efforts will likely be merged. Although many details remain to be argued over, the outlines of the next version of HTML are becoming clear.
This new version of HTML—usually called HTML 5, although it also goes under the name Web Applications 1.0—would be instantly recognizable to a Web designer frozen in ice in 1999 and thawed today. There are no namespaces or schemas. Elements don't have to be closed. Browsers are forgiving of errors. A p is still a p, and a table is still a table.
At the same time, this proverbial unfrozen caveman Web designer would encounter some new and confusing elements. Yes, old friends like div remain, but now HTML includes section, header, footer, and nav as well. em, code, and strong are still present, but so are meter, time, and m. img and embed continue to be used, but now there are video and audio too. However, closer inspection by the caveman designer would reveal that these elements aren't that different. Many of them might be things the designer needed back in 1999 but didn't have. All these new elements are easily learned by simple analogy with elements the designer already understands. In fact, they're a lot easier to learn than Ajax or CSS.
Finally, when the caveman fired up the 300MHz laptop running Windows 98 that was also frozen in 1999, they might be astonished to realize that the new pages display fine in Netscape 4 and Windows® Internet Explorer® 5. Sure, the browser wouldn't recognize or do anything with the new elements, but the page still displays, and the content is all there.
That's not a happy coincidence. HTML 5 was explicitly designed to degrade gracefully in browsers that don't support it. The reason is simple: We are all cave people. Browsers now have tabs, CSS, and XmlHttpRequest, but their HTML renderers are stuck in 1999. The Web can't move forward without accounting for the installed base. HTML 5 understands this. It offers real benefits to page authors today while promising even more to page readers tomorrow as browsers are slowly upgraded. With that in mind, let's look at what HTML 5 brings you.
Structure Even well-formed HTML pages are harder to process than they should be because of the lack of structure. You have to figure out where the section breaks go by analyzing header levels. Sidebars, footers, headers, navigation menus, main content sections, and individual stories are marked up by the catch-all div element. HTML 5 adds new elements to specifically identify each of these common constructs:
-
section: A part or chapter in a book, a section in a chapter, or essentially anything that has its own heading in HTML 4 -
header: The page header shown on the page; not the same as theheadelement -
footer: The page footer where the fine print goes; the signature in an e-mail message -
nav: A collection of links to other pages -
article: An independent entry in a blog, magazine, compendium, and so forth

JavaFX Script is a highly productive scripting language that enables content developers to create rich media and content for deployment on Java environments. This article, aimed at traditional Java developers, is a brief but thorough introduction to Sun's exciting new technology.
JavaFX Pad - A JNLP that starts the JavaFX Pad application, wuhich will allow yo to iteratively enter JavaFX code and watch the results at the same time.
OpenJFX Website - The Official Site for JavaFX Technology.
Getting started with the JavaFX Script for Swing Programmers - This tutorial shows you how to use the graphical widgets present in the JavaFX scripting language. Because many of these widgets map directly to the underlying Swing components, those who are familiar with programming Swing will be able to read quickly through this document.
JavaFX Script 2D Graphics Tutorial - Similar to JavaFX Pad, this JNLP will help you learn to use the 2D graphics functionality inside JavaFX technology.

Developer's Tool - The Integrated Development Environment (IDE)
Developer's Tool - The Integrated Development Environment (IDE)
What is an IDE?
An integrated development environment (IDE), also known as integrated design environment and integrated debugging environment, is a type of computer software that assists computer programmers in developing software.
IDEs normally consist of a source code editor, a compiler and/or interpreter, build-automation tools, and (usually) a debugger. Sometimes a version control system and various tools to simplify the construction of a GUI are integrated as well. Many modern IDEs also integrate a class browser, an object inspector and a class hierarchy diagram, for use with object oriented software development. Although some multiple-language IDEs are in use, such as the Eclipse IDE, JDeveloper, Code::Blocks, Komodo IDE, NetBeans, Borland Developer Studio, KDevelop or Microsoft Visual Studio, typically an IDE is devoted to a specific programming language, as in the Visual Basic IDE.
An example for a multiple-language IDE, Eclipse's base installed language is Java. It also has plugins for C/C++, Python, Perl, Ruby, Fortran, Cobol, PHP, JSP/Servlet, J2EE, OOD/OOP design tools and many more plugins. These all can be installed on the same IDE at the same time. They all have their own debugger and integrated IDE options.

History
IDEs initially became necessary when doing development in front of a console or terminal. Early languages did not have one, since they were prepared using flowcharts, coding forms, and keypunches before being submitted to a compiler. BASIC was the first language to be created with an IDE (and was also the first to be designed for use while sitting in front of a console or terminal). Its IDE (part of the Dartmouth Time Sharing System) was command-based, and therefore did not look much like the menu-driven, graphical IDEs of today. However it seamlessly integrated editing, file management, compilation, debugging and execution in the manner characteristic of a modern IDE.
Today, the term "IDE" is a contrast to unrelated command-line tools, such as vi, emacs, or make. While one could think of Unix as an IDE, most developers think of an IDE as being a single program with an IDE-style interface, in which all development is done. This program provides typically large numbers of features for authoring, modifying, compiling, deploying and debugging software - the idea being that the IDE abstracts the configuration necessary to piece together command line utilities in a cohesive unit, which theoretically reduces the time to learn a language, and increases developer productivity. It is also thought that the tight integration of various development tasks can lead to further productivity increases (for example, code can be compiled while being written, providing instant feedback on syntax errors). While most modern IDEs are graphical, IDEs in use before the advent of windowing systems (such as Microsoft Windows or X11) were text-based, using function keys or hotkeys to perform various tasks (Turbo Pascal is a common example).
An interesting development is the emergence and popularization of Open Source IDE such as Eclipse and NetBeans in recent years. The combination of the Open Source philosophy with an open, extensible framework, encourages the creation of a community of people to extend the capabilities of the IDE, allowing even exotic languages and applications to be supported by the environment.
