For a web application, It is always a good idea to provide access to it from other platforms like mobile or desktop programs.

As web designers/developers, desktop applications are harder to create considering they have a totally different environment.

In order to fill this gap, we can make use of site-specific browsers which enable us to lock a website inside an application-looking browser that can interact with the system tray/dock & display notifications.

Some usage examples for site-specific browsers:

• displaying new orders, support tickets for an e-commerce website
• showing system tray alerts when a new visitor visits your website
• or even locking your whole application inside a site-specific browser and offering it as a desktop application.

To sum up, they simply help us convert a website into a desktop application. Here are free & mature tools for creating site-specific browsers:

Mozilla Prism (Win-Mac)

Prism is a very easy-to-customize tool that supports Windows & Mac.

Applications created can be:

• minimized to system tray/dock & a navigation can be added there
• set to display status messages & popups in the system tray/dock

Prism apps. will be running seperately from the browser & will stay alive even if the browser isn't.

P.S. You can also read a more detailed post about Prism at WRD.

• limitting the number of <items> to be processed
• excluding XML nodes with certain words, numbers or symbols

The platform is definitely a gold mine for making cross-browser tests quickly & easily.

P.S. Spoon allows you to convert your own apps to Spoon apps & post them on the web. You can check the platform's homepage for that.

Many PHP developers use print_r() & var_dump() for debugging which output hard to read/unformatted results.

Krumo is a replacement for these functions which can display structured information about any PHP variable.

Once Krumo is ran, the output is displayed in a collapsible DHTML tree built around the structure of the dumped PHP variable.

Also, it speeds up the debugging process by the ability of turning it "off" rather than disabling every dumping route inside the code.

Krumo runs on PHP 5 & to see how useful it can be, check the examples.

There is also a full-featured knowledgebase, that supports unlimited categories, where users can find answers to their questions themselves.

P.S. HESK has a free & paid version where the only limitiation of the free version is a backlink.

Closure Tools is set of opensource (release info) developer tools by Google which are used while building Gmail, Google Maps, Google Docs  & many others.

The tools include a JavaScript compiler, library & templating system.

JavaScript Compiler

It compiles JavaScript into compact, high-performance code. The compiler removes dead code and rewrites and minimizes what's left so that it downloads and runs quickly.

It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.

The compiler also offers a Firebug extension, named Inspector, for better debugging.

Closure Library

It is a broad, well-tested, modular, & cross-browser JavaScript library.

Only what you need can be pulled from a large set of reusable UI widgets, controls, lower-level utilities for DOM manipulation, server communication, animation, data structures, unit testing, rich-text editing, & more.

Closure Templates

They simplifty the task of dynamically generating HTML.

In contrast to traditional templating systems, in which you use one big template per page, you can think of Closure Templates as small components that you compose to form your user interface.
