Open Source Resources for Web Application Developers

CKEditor is a Version 3.0 of FCKeditor. After almost two years of intensive development, the first stable version of CKEditor 3.0 has finally released.

CKEditor is a complete rewrite of our so loved FCKeditor, which got a bit old after six years of great success. Not to say that FCKeditor is doing bad, but there are some new things we could bring to it, and CKEditor is the result of it. There are dozens of new features in CKEditor.

CKEditor is fast to load and fast to use. The development team stayed focused to bring the best performance you can have, using all modern best practices. You’ll be amazed with it.

You’ll note that they have also a brand new UI based on the Kama skin. Other than modern, Kama is colorful like a chameleon, so you can precisely match its color to your needs. This is an innovative and unique feature you’ll find in CKEditor only.

The CKEditor code is also much different now. It’s up to date with the new JavaScript development requirements, offering a rich and powerful integration and interaction API. The editor is totally plugin based, and it can be extended and modified in all senses to fit all needs.

Requirements: Internet Explorer, Mozilla Firefox, Google Chrome, Safari and Opera

MegaZine 3 uses a completely dynamic approach, allowing full configuration through an external XML file. This makes it easy to set up books even if you do not even own the Flash IDE.

MegaZine 3 automatically generates a control bar that allows jumping to every individual page. It also generates thumbnails for the pages, to make it easier for the user to find a page again, or getting a first impression.

Chronoscope is an open source release of a charting and visualization platform for GWT, used as the centerpiece of Timepedia’s website. Chronoscope provides a high performance, cross browser platform for visualizing possibly large and complex datasets. It supports interactive framerates on datasets with tens of thousands of points by using multiresolution representation and incremental streaming.

When the number of points about to be plotted exceeds a certain heuristic, Chronoscope falls back to a lower resolution representation of the dataset, which can be provided by the user, or automatically calculated by various filtering algorithms. This is similar to mip-mapping techniques commonly used in 3D graphics to reduce bandwidth and decrease aliasing. It also gives non-programmers intuitive controls over almost every aspect of the look of a visualization.

Requirements: Google Web Toolkit

Cappuccino is an open source application framework for developing applications that look and feel like the desktop software users are familiar with.

Cappuccino is built on top of standard web technologies like JavaScript, and it implements most of the familiar APIs from GNUstep and Apple’s Cocoa frameworks. When you program in Cappuccino, you don’t need to concern yourself with the complexities of traditional web technologies like HTML, CSS, or even the DOM. The unpleasantries of building complex cross browser applications are abstracted away for you.

Cappuccino was implemented using a new programming language called Objective-J, which is modelled after Objective-C and built entirely on top of JavaScript. Programs written in Objective-J are interpreted in the client, so no compilation or plugins are required.

Instead of doing all or most of the work on the server, Cappuccino applications do as much as possible in the client. A typical application would never reload, but rather send and recieve data using traditional AJAX techniques and then present that data in the client code.

You’re writing an email to invite a friend to meet at a local San Francisco restaurant that neither of you has been to. You’d like to include a map. Today, this involves the disjointed tasks of message composition on a web-mail service, mapping the address on a map site, searching for reviews on the restaurant on a search engine, and finally copying all links into the message being composed. And you haven’t even really sent a map or useful reviews—only links to them.

Mozilla Labs has announced the launch of Ubiquity. Ubiquity empower users to control the web browser with language-based instructions. (With search, users type what they want to find. With Ubiquity, they type what they want to do.) And it enables on-demand, user-generated mashups with existing open Web APIs. (In other words, allowing everyubone–not just Web developers–to remix the Web so it fits their needs, no matter what page they are on, or what they are doing.)

Ubiquity lets you map and insert maps anywhere; translate on-page; search amazon, google, wikipedia, yahoo, youtube, etc.; digg and twitter; lookup and insert yelp review; get the weather; syntax highlight any code you find; and a lot more. Ubiquity “command list” to see them all.

All of the code underlying the Ubiquity experiment is being released as open source software under the  GPL/MPL/LGPL tri-license as well.
