Die Entwickler der Javascript-Bibliothek ExtJS veröffentlichen die Final Beta der Version 3.2 und beseitigen damit  Fehler und fügen einige neue Funktionen hinzu.

While the beta announcement covers most of the details of the new release, a few additional changes made their way in between then and now:

• Ext.ux.SliderTip has been incorporated into the library as Ext.slider.Tip
• Ext.ux.form.SliderField has been incorporated into the library as Ext.form.SliderField
• Significant performance improvements to the Box Layouts, resulting in a 25% speed increase in many cases
• Performance improvements to AnchorLayout and ColumnLayout
• New Themes Viewer example
• Updated Charts
• 60 bug and enhancement tickets have been closed since the beta release

Eine neue Javascript-Engine im Opera 10.52 für den Mac soll die Performance erhöhen. Die Norwegegische Softwareschmiede  Opera hat seinen Browser  für Mac OS X in Version 10.52 veröffentlicht. Die neue Javascript-Engine “Carakan” soll für einen mächtigen  Geschwindigkeits-Boost sorgen. Nach Angaben der Opera Entwickler

Unsere neue JavaScript-Engine ist bis zu 7 Mal schneller.

The new Opera browser for Mac is now more than ten times faster, according to speed comparisons between Opera 10.52 and Opera 10.10. With a powerful new feature set tailored for Mac computers, Opera delivers a much improved user experience. Download Opera for Mac at www.opera.com.

The new Opera is designed with Mac in mind. This version boasts an improved user interface, Cocoa integration, multi-touch trackpad gestures and Growl support. This, combined with the unprecedented speed from the new JavaScript engine, Carakan, and the new graphic library, Vega, provides a faster and smoother browsing experience. The new Opera also features the latest in Web standards, including leading SVG support and HTML 5 video.

Pixastic is an experimental (beta) Image Processing Library which allows you to perform a variety of operations on images using just a bit of JavaScript. The effects supported out of the box include desaturation/greyscale, invert, flipping, brightness/contrast adjustment, hue/saturation, emboss, blur, and many more.

Pixastic works by utilizing the HTML5 Canvas element which provides access to raw pixel data, thereby opening up for more advanced image effects. This is where the “experimental” part comes into play. Canvas is only supported by some browsers and unfortunately Internet Explorer is not one of them. It is however well supported in both Firefox and Opera and support for Safari only just arrived with the recent Safari 4 (beta) release. Chrome currently works in the dev channel. A few of the effects have been simulated in IE using the age old proprietary filters. While these filters are much faster than their Canvas friends, they are few and limited. Hopefully we will one day have real Canvas on IE as well.

In 12 Schritten zum MooTools Master lautet das Motto des Februar MooTools Roundup.

Jacob Thornton’s NetTuts article, 12 Steps to MooTools Master, is a high-level introduction to the MooTools JavaScript framework. The informative article touches on such MooTools topics as Mutators, Prototypal Inheritance, custom events, binding, and more. This tutorial probably isn’t for the complete beginner, but is a good place to start for people still relatively new to MooTools and those considering it for the first time.

Hier der ganze Beitrag

The short story

Here’s the recipe: MooTools modules Native, Class, and Class.Extras (24k uncompressed); jQuery; and Class.Mutatotors.jQuery. Write a MooTools Class and use jQuery for the DOM.

Class.Mutatotors.jQuery

This mutator automatically extends the jQuery object with the class, so you can use conventional jQuery syntax to instantiate and control the class.

Ein schönes jQuerry Plugin gibt es bei workshop.rs. Mit dem jqIsoText lassen sich Texte mit einem pseudo-isometrischen Effekt darstellen. Das Plugin funktionier mit Safari 2+, Internet Explorer 6+, Firefox 2+, Google Chrome 3+, Opera 9+.

jQuery 1.4.2 is now out! This is the second minor release on top of jQuery 1.4, fixing some outstanding bugs from the 1.4 release and landing some nice improvements.

I would like to thank the following people that provided patches for this release: Ben Alman, Justin Meyer, Neeraj Singh, and Noah Sloan.

Downloading

As usual, we provide two copies of jQuery, one minified (we now use the Google Closure Compiler as the default minifier) and one uncompressed (for debugging or reading).

• jQuery Minified (24kb Gzipped)
• jQuery Regular (155kb)

You can feel free to include the above URLs directly into your site and you will get the full performance benefits of a quickly-loading jQuery.

Additionally you can also load the URLs directly from either Google or Microsoft’s CDNs:

• http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js
• http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.2.min.js
