Droptiles: Metro style Live Tiles enabled Web 2.0 Dashboard
Droptiles is an Open Source Windows 8 Start like Metro style Web 2.0 Dashboard. It builds the experience using Tiles. Tiles are mini apps that can fetch data from external sources. Clicking on a tile launches the full app. Apps can be from any existing website to customized website specifically built to fit the Dashboard experience. Droptiles is built almost entirely of HTML, Javascript and CSS and thus highly portable to any platform. The sample project is built using ASP.NET to show some server side integration, like Signup, Login and getting dynamic data from server. But with very little change you can port it to PHP, Ruby, JSP or any other platform. Droptiles is the sequel of my Dropthings, which is the first Open Source Web 2.0 Dashboard.

UFrame: goodness of UpdatePanel and IFRAME combined
UFrame combines the goodness of UpdatePanel and IFRAME in a cross browser and cross platform solution. It allows a DIV to behave like an IFRAME loading content from any page either static or dynamic. It can load pages having both inline and external Javascript and CSS, just like an IFRAME. But unlike IFRAME, it loads the content within the main document and you can put any number of UFrame on your page without slowing down the browser. It supports ASP.NET postback nicely and you can have DataGrid or any other complex ASP.NET control within a UFrame. UFrame works perfectly with ASP.NET MVC making it an replacement for UpdatePanel. Best of all, UFrame is implemented 100% in Javascript making it a cross platform solution. As a result, you can use UFrame on ASP.NET, PHP, JSP or any other platform.

Fast ASP.NET web page loading by downloading multiple javascripts in batch
A web page can load a lot faster and feel faster if the javascripts on the page can be loaded after the visible content has been loaded and multiple javascripts can be batched into one download. Browsers download one external script at a time and sometimes pause rendering while a script is being downloaded and executed. This makes web pages load and render slow when there are multiple javascripts on the page. For every javascript reference, browser stops downloading and processing of any other content on the page and some browsers (like IE6) pause rendering while it processes the javascript. This gives a slow loading experience and the web page kind of gets 'stuck' frequently. As a result, a web page can only load fast when there are small number of external scripts on the page and the scripts are loaded after the visible content of the page has loaded.

Fast page loading by moving ASP.NET AJAX scripts after visible content
ASP.NET ScriptManager control has a property LoadScriptsBeforeUI, when set to false, should load all AJAX framework scripts after the content of the page. But it does not effectively push down all scripts after the content. Some framework scripts, extender scripts and other scripts registered by Ajax Control Toolkit still load before the page content loads. The following screen taken from www.dropthings.com shows several script tags are still added at the beginning of <form> which forces them to download first before the page content is loaded and displayed on the page. Script tags pause rendering on several browsers especially in IE until the scripts download and execute. As a result, it gives user a slow loading impression as user stares at a white screen for some time until the scripts before the content download and execute completely. If browser could render the html before it downloads any script, user would see the page content immediately after visiting the site and not see a white screen. This will give user an impression that the website is blazingly fast (just like Google homepage) because user will ideally see the page content, if it's not too large, immediately after hitting the URL.

My first book - Building a Web 2.0 Portal with ASP.NET 3.5
My first book "Building a Web 2.0 Portal with ASP.NET 3.5" from O'Reilly is published and available in the stores. This book explains in detail the architecture design, development, test, deployment, performance and scalability challenges of my open source web portal http://dropthings.omaralzabir.com. Dropthings is a prototype of a web portal similar to iGoogle or Pageflakes. But this portal is developed using recently released brand new technologies like ASP.NET 3.5, C# 3.0, Linq to Sql, Linq to XML, and Windows Workflow foundation. It makes heavy use of ASP.NET AJAX 1.0. Throughout my career I have built several state-of-the-art personal, educational, enterprise and mass consumer web portals. This book collects my experience in building all of those portals.
