“Wir hatten aus einer in der Regel sehr zuverlässigen Quelle die Information, dass Nikon demnächst eine Kamera mit dem Modellnamen D400 ankündigen wird. Dementsprechend hatten wir ein Buch dazu bereits fest eingeplant. Bislang hat sich das leider nicht bewahrheitet und uns liegen keine neueren Infos darüber vor, ob und wann Nikon eine Kamera diese Namens herausbringen wird.”

Google translation:

“We had a usually very reliable source of information that Nikon will soon announce a camera with the model name D400. Accordingly, we had a book about this already scheduled. So far, unfortunately this is not true and we are no recent information on whether and when Nikon will release a camera that name.”

”A ”’software framework”’ est une conception réutilisables d’un système logiciel (ou système). Cela est exprimé comme un ensemble de[[:Wikipedia:abstract class|abstract class]]es and the way their instances collaborate for a specific type of software. Software frameworks can be [[:Wikipedia:Object-oriented programming|object-oriented designs]]. Although designs don’t have to be implemented in an object-oriented language, they usually are. A software framework may include support programs, code [[:Wikipedia:Libraries|libraries]]<ref>[[PHP libraries]] bundled with Joomla!</ref>, a [[:Wikipedia:JavaScript|scripting language]]<ref>[[JavaScript libraries]] bundled with Joomla!</ref>, or other software to help develop and ”glue together” the different components of a software project. Various parts of the framework may be exposed through an application programming interface ([[:Wikipedia:Application programming interface|API]]).”

[[:Category:Joomla! 1.5|Joomla! 1.5]] is a three tiered system:-
* The top, Extensions layer, consists of [[Extension|Extensions]] to the Joomla [[Framework]] and its applications:
** [[Module|Modules]]
** [[Component|Components]]
** [[Template|Templates]]
* The middle, Application layer, consists of applications that extend the Framework [[JApplication]] class. Currently there are four applications included in the Joomla distribution:-
** [[JInstallation]] is responsible for installing Joomla on a web server and is deleted after the installation procedure has been completed.
** [[JAdministrator]] is responsible for the back-end Administrator.
** [[JSite]] is responsible for the front-end of the website.
** [[XML-RPC]] supports remote administration of the Joomla website.
* The bottom, Framework layer, consists of:-
** the Joomla [[Framework]] itself, whose classes are listed below.
** [[Library|Libraries]] that are required by the [[Framework]] or are installed for use by third-party developers.
** [[Plugin|Plugins]] extend the functionality available in the [[Framework]].

== Packages and Classes ==
The classes in the {{jf}} are loosely grouped into several different packages, listed below. The links will take you to further information about each class including, where possible, examples of use. You can also browse the Joomla Framework and included libraries on [http://api.joomla.org api.joomla.org] which is automatically generated by the phpDocumentor package from an analysis of the Joomla! source code, making use of specially formatted comments embedded in the source code itself. These two resources, one manually maintained, the other automatic, are intended to complement one another.

If you would like to help us improve this resource, please read [[API Reference Project]].

For an alphabetical list of class names click on the "Class" column heading.

So far, the Google Nexus One unveiling has been the biggest mobile phone news of this festive CES week, but it’s far from the only cell-related news:

• Verizon will be getting both the Palm Pre and Pixi in Plus-sized packages–essentially doubling the storage capacity each one currently sports as currently offered from Sprint (via IntoMobile). An official announcement with release schedule will be happening later today. And it looks like the Pre and Pixi might be going the GSM route over to AT&T later this year as well.
• AT&T will also get into the Android business in 2010 with five planned releases in the first half of the year, including the Dell Mini 3 (currently available in China).

  

  (image courtesy of Wired’s Gadget Lab)
• While not confirmed, one of those Android phones set for AT&T’s stable should be the just announced Motorola Backflip, which rejiggers the typical touchscreen/QWERTY keyboard design we’ve become accustomed to. Instead of hiding sliding out from under the screen, the keyboard folds out from the back (meaning, also, that they keyboard is visible when folded closed).

  Another innovation is the Backtrack trackpad placed on the back of the display and accessible when the phone is flipped open, allowing you to navigate the Backflip’s UI (and potentially play games) without getting your fingers in the way of the screen. And speaking of the UI, it utilizes the social networking-centric MotoBlur overlay to the Android 1.5 OS that’s found on the current Motorola Cliq. Check out Electronista and MobileBurn for video demos.

• For Windows Mobile fans, Gizmodo reports that T-Mobile has announced the launch later this spring of the HTC HD2 smartphone, which runs the same super-fast 1 GHz Snapdragon processor that’s included in the Google Nexus One. It will also sport a 4.3-inch capacitive touch display, Windows Mobile 6.5, and the HTC Sense UI overlay. You can sign up for updates on its release and pricing here.

• And finally… for a bit of profanity-laced NSFW humor, check out this video from Landline TV outlining Google’s newest challenger to the iPhone (via IntoMobile). Warning: it does make liberal use of the F-word (and, to borrow from Craig Ferguson, I’m not talking about “fandango”).
