XPCOM ( Cross Platform Component Object Model ) is a cross-platform component model from Mozilla.

On the developer side, XPCOM lets you write components in C ++, C, JavaScript, Python, or other languages for which special bindings have been created, and compile and run those components on dozens of different platforms, including these and others where Mozilla itself is supported.

The flexibility to reuse the XPCOM components from the Gecko library and develop new components that run on different platforms facilitates rapid application development and results in an application that is more productive and easier to maintain.

The networking library, for example, is a set of XPCOM components that can be accessed and used by any Mozilla application.

XPConnect ( Cross Platform Connect ) is a technology which enables simple interoperation between XPCOM and JavaScript.

A main goal is that objects communicating from either side of an XPCOM style interface should not generally need to know or care about the implementation language of the object on the other side of the interface.

In particular, the technology is heavily based on XPCOM, which is similar to Microsoft COM.

At the end of 2004, all major browser companies using NPAPI agreed on NPRuntime as an extension to the original NPAPI to supply scripting, via an API that is similar in style to the old C-style NPAPI and is independent of other browser technologies like Java or XPCOM.

* XPCOM ( Cross Platform Component Object Model ) — developed by Mozilla for applications based on it ( e. g. Mozilla Application Suite, SeaMonkey 1. x )

Applications that want to access the various Mozilla XPCOM libraries ( networking, security, DOM, etc.

However, many of the powerful features of Mozilla ( such as privileged XPCOM objects ) remain unavailable to unprivileged XUL documents unless the script has a digital signature, and unless the user obtains grants of certain privileges to the application.

Mozilla was already using XPCOM to define the interfaces to many objects implemented in C ++.

Examples of memory leak detection tools used by Mozilla are the XPCOM Memory Leak tools.

File I / O, security, password management, and profiles are also separate XPCOM components that programmers can use in their own application development.

XPConnect glues the front end to the C ++ or C programming language-based components in XPCOM, and it can be extended to include scripting support for other languages: PyXPCOM already offers support for Python, PerlConnect and plXPCOM provide support for Perl, and there are efforts underway to add CLI and Ruby language support for XPConnect.

XPCOM adds a lot of code for marshalling objects between different usage contexts ( e. g. different languages ).

This leads to code bloat in XPCOM based systems.

The Gecko developers are currently trying to reduce superfluous uses of XPCOM in the Gecko layout engine.

Software systems based on IDLs include Sun's ONC RPC, The Open Group's Distributed Computing Environment, IBM's System Object Model, the Object Management Group's CORBA ( which implements OMG IDL, an IDL based on DCE / RPC ), Mozilla's XPCOM, Facebook's Thrift and WSDL for Web services.

Venkman builds on the js / jsd portion of Bandhauer's 1998 work, exposing it as an XPCOM component.

XPConnect allows JavaScript objects to transparently access and manipulate XPCOM objects.

It also enables JavaScript objects to present XPCOM compliant interfaces to be called by XPCOM objects.

For remote HTML / XHTML / XUL documents, most XPCOM objects are not accessible by the scripts as they have limited privileges due to security reasons.

It also included a new JavaScript engine ( JägerMonkey ) and better XPCOM APIs.

But there's one thing I never seen or heard of, one thing I just don't think there is, and that's a sportin' way o' killin' a man ''!!

I seized the rack and made a western-style flying-mount just in time, one of my knees mercifully landing on my duffel bag -- and merely wrecking my camera, I was to discover later -- my other knee landing on the slivery truck floor boards and -- but this is no medical report.

The true artist is like one of those scientists who, from a single bone can reconstruct an animal's entire body.

In fact, one important aspect of their very religion is the annihilation of men ''.

It took thirty of our women almost six moons to build this one, which is higher and stronger than the old one.

I clapped the big man with the bleached hair on his shoulder and said heartily, hoping it would make an impression on the women: `` This one is the maku Frayne.

`` This one is a tender chicken, oui??

but he presents it publicly so enmeshed in hypocrisy that it is not an honest one.

My definition of this much abused adjective is that a reconstructed rebel is one who is glad that the North won the War.

For one thing, this is not a subject often discussed or analyzed.

The general acceptance of the idea of governmental ( i.e., societal ) responsibility for the economic well-being of the American people is surely one of the two most significant watersheds in American constitutional history.

A third, one of at least equal and perhaps even greater importance, is now being traversed: American immersion and involvement in world affairs.

Today, as new nations rise from the former colonial empires, nationalism is one of the hurricane forces loose in the world.

Historically, however, the concept is one that has been of marked benefit to the people of the Western civilizational group.

It is one of the ironic quirks of history that the viability and usefulness of nationalism and the territorial state are rapidly dissipating at precisely the time that the nation-state attained its highest number ( approximately 100 ).

But it is more than irony: one of the main reasons why nationalism is no longer a tenable concept is because it has spread throughout the planet.

Accidental war is so sensitive a subject that most of the people who could become directly involved in one are told just enough so they can perform their portions of incredibly complex tasks.

Only one rule prevailed in my conversations with these men: The more highly placed they are -- that is, the more they know -- the more concerned they have become.

However, the system is designed, ingeniously and hopefully, so that no one man could initiate a thermonuclear war.
