"HTML 5 experimentation and demos I've hacked together. Click on the browser support icon or the technology tag to filter the demos (the filter is an OR filter)."

(Not strictly speaking ASP.Net MVC, but very relevant to MVC sites too.) "Mayday detects changes in users behaviour, validation and javascript errors providing insights into users experience & what problems happen."

"Super Simple Auto Spriting, Minification and Bundling solution No need to tell RequestReduce where your resources are Your CSS and Javascript can be anywhere - even on an external host RequestReduce finds them at runtime automatically"

"One thing that always annoys me when working on a web app is having to write those inevitable pages full of admin functions some of which are just a single button. When hacking up one such page I had a thought - a plug in library providing a command line for your web app might save me a lot of time. NetBash is what I came up with."

"FubuMVC is a "Front Controller" pattern-style MVC framework designed for use in web applications built on ASP.NET."

"In general, you should avoid building strings of HTML in your applications. There are plenty of template/view engines that are much more suitable for generating dynamic markup. However, there are some situations that require you to build snippets of HTML from code (e.g., view extensions in FubuMVC or HtmlHelper extensions in ASP.NET MVC). HtmlTags is the best way to build those snippets."

"Optimizing application performance is a key element for business. There are several ways by which we can optimize the applications performance. It can be done either by server side code optimization, caching or some client side optimization. In this post I am going to discuss about one handy and smart way to optimize web applications performance using Bundling and Minification features which is introduced with ASP.NET 4.5 Developer Preview. ASP.NET 4.5 Developer Preview introduced bundling, which combines multiple JavaScript files for faster loading with less number of requests for download and minification, which reduces the size of JavaScript and CSS files by removing unneeded characters . Combination of these bundling and minification helps web pages to load very faster. Let's have a looks how it works."

" Naked Objects takes a domain object model, written as POCOs but following a few very simple conventions, and dynamically creates one or more complete user interfaces for it, using reflection (not 'code generation' or 'scaffolding'). It is highly effective in support of Domain-Driven Design, OO Modelling, and/or Agile Development. Naked Objects MVC builds upon the core framework to create a complete web-based user interface, using ASP.NET MVC 3. The generic user interface may be customised via the .CSS, by adding custom views, or custom controllers, as needed. Entity Framework is used to persist objects on a database. Security may be handled simply via Forms Authentication and attribute-based authorisation, or more comprehensively via Microsoft WIF and an STS. "

"TekPub is an interesting study in a company who started on ASP.NET MVC and quickly moved to Ruby on Rails. InfoQ had the opportunity to talk with Rob and James about TekPub and their journey from using ASP.NET MVC to Ruby on Rails."

Quite a thought provoking interview for us .Net veterans.

Here are 3 other groups, 2 of mine, and 1 of Johann's that might be more suited to some of the recent shared links:
Javascript Masters (and wannabes) http://groups.diigo.com/group/javascript-masters-and-wannabes

"jQuery throttle / debounce allows you to rate-limit your functions in multiple useful ways. Passing a delay and callback to $.throttle returns a new function that will execute no more than once every delay milliseconds. Passing a delay and callback to $.debounce returns a new function that will execute only once, coalescing multiple sequential calls into a single execution at either the very beginning or end."

" An HttpModule that hooks onto the Response.Filter property of the current request and tries to compress the output, based on what the browser supports"

" The open source HttpCompress library is very easy to incorporate into an ASP.NET web site. First, download the latest version of HttpCompress from the official web site. "

"In this post I would like to cover a couple of asynchronous patterns that are available in ASP.NET MVC and jQuery as it is used in MVC."

"The AsyncController class enables you to write asynchronous action methods. You can use asynchronous action methods for long-running, non-CPU bound requests. This avoids blocking the Web server from performing work while the request is being processed. A typical use for the AsyncController class is long-running Web service calls."

" AsyncController is introduced in ASP.NET MVC 2 while SessionLess controller is introduced in ASP.NET MVC 3. AsyncController allows you to perform long running I/O operation(s) without making your thread idle(i.e., waiting for I/O operations to complete). On the other hand, SessionLess controller allows you to execute multiple requests simultaneously for single user, which otherwise execute multiple requests sequentially due to session synchronization. Understanding these concepts may be easy for you but I have seen a lot of guys become confused on these concepts. In this article, I will show you how to use AsyncController and SessionLess controller in ASP.NET MVC application. I will also compare them and tell you what to use when, where, and the why."

This is some awesome out of the box thinking!

"jQuery's $(document).ready() event is something that you probably learned about in your earliest exposure to jQuery and then rarely thought about again. The way it abstracts away DOM timing issues is like a warm security blanket for code running in a variety of cold, harsh browser windows."

"A new ASP.NET MVC project includes preconfigured Membership, Profile and RoleManager providers right out of the box. Try it yourself - create a ASP.NET MVC application, crack open the web.config file and have a look. "

"A little bit of thinking and compromise can remove unnecessary complexity from the routes in an MVC application. "
