OpenLaszlo is an open source platform for creating zero-install web applications with the user interface capabilities of desktop client software.

"Apache Tapestry is an open-source framework for creating dynamic, robust, highly scalable web applications in Java. Tapestry complements and builds upon the standard Java Servlet API, and so it works in any servlet container or application server. Tapestry divides a web application into a set of pages, each constructed from components. This provides a consistent structure, allowing the Tapestry framework to assume responsibility for key concerns such as URL construction and dispatch, persistent state storage on the client or on the server, user input validation, localization/internationalization, and exception reporting. Developing Tapestry applications involves creating HTML templates using plain HTML, and combining the templates with small amounts of Java code. In Tapestry, you create your application in terms of objects, and the methods and properties of those objects -- and specifically not in terms of URLs and query parameters. Tapestry brings true object oriented development to Java web applications. "

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Developed four years ago by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly. Django focuses on automating as much as possible and adhering to the DRY principle. Dive in by reading the overview → When you're ready to code, read the installation guide and tutorial.

Prototype is a JavaScript Framework that aims to ease development of dynamic web applications. Featuring a unique, easy-to-use toolkit for class-driven development and the nicest Ajax library around, Prototype is quickly becoming the codebase of choice for web application developers everywhere.

According to Yahoo!'s Exceptional Performance Team, 40% to 60% of Yahoo!'s users have an empty cache experience and about 20% of all page views are done with an empty cache (see this article by Tenni Theurer on the YUIBlog for more information on browser cache usage). This fact outlines the importance of keeping web pages as lightweight as possible. Improving the engineering design of a page or a web application usually yields the biggest savings and that should always be a primary strategy. With the right design in place, there are many secondary strategies for improving performance such as minification of the code, HTTP compression, using CSS sprites, etc. In terms of code minification, the most widely used tools to minify JavaScript code are Douglas Crockford's JSMIN, the Dojo compressor and Dean Edwards' Packer. Each of these tools, however, has drawbacks. JSMIN, for example, does not yield optimal savings (due to its simple algorithm, it must leave many line feed characters in the code in order not to introduce any new bugs). The goal of JavaScript and CSS minification is always to preserve the operational qualities of the code while reducing its overall byte footprint (both in raw terms and after gzipping, as most JavaScript and CSS served from production web servers is gzipped as part of the HTTP protocol). The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin (becoming 10% after HTTP compression). Starting with version 2.0, the YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter's regular-expression-based CSS minifier.

My view of GWT is changing. When I wrote 5 GWT Anti-Patterns I saw it as the framework controlling my entire application. Now it's my glue. GWT is a wonderful foundation holding together the different parts of your application. It can grow and expand to new technologies and uses we haven't thought of yet, but it can also hold us back. You can get stuck in GWT and never find your way out. Each of these four anti-patterns addresses different ways to write code you wish you hadn't. The solutions are all about opening doors instead of closing them.

not very useful. I prefer script.aculo.us + prototype

Due to browsers' prohibition on cross domain XMLHTTP calls, all AJAX websites must have a server side proxy to fetch content from external domains like Flickr or Digg. From the client-side JavaScript code, an XMLHTTP call goes to the server-side proxy hosted on the same domain, and then the proxy downloads the content from the external server and sends back to the browser. In general, all AJAX websites on the Internet that are showing content from external domains are following this proxy approach, except for some rare ones who are using JSONP. Such a proxy gets a very large number of hits when a lot of components on the website are downloading content from external domains. So, it becomes a scalability issue when the proxy starts getting millions of hits. Moreover, a web page's overall load performance largely depends on the performance of the proxy as it delivers content to the page. In this article, we will take a look at how we can take a conventional AJAX Proxy and make it faster, asynchronous, continuously stream content, and thus make it more scalable.
