Recalling the lambda notation…

I found an interesting guide for (not obvious) Javascript code optimization.

Remember these quotes before reading the article:

• “Premature optimization is the root of all evil” - Donald Knuth
• “On the othere hand, we cannot ignore efficiency” - Jon Bentley

The article is here.

This article introduces AJAX to ASP.NET developers implementing an example web page in different ways using ASP.NET Atlas, ASP.NET callbacks, Ajax.Net, Anthem.Net and MagicAjax.Net.

Last week IE Team has released a new version of IE Developer Toolbar. Althrough it’s still beta 2 (as latest), it’s a new build.

You can download it from here.

1. Introduction to Ajax
2. Make asynchronous requests with JavaScript and Ajax
3. Advanced requests and responses in Ajax
4. Exploiting DOM for Web response

A really nice and working sample.

ZDNet.com presents an article with a list of websites using AJAX/Web 2.0 technology. Many of them are office software. I’ve tried some and I’m impressed, but most of them are in an early stage.

I tried:

• http://www.aypwip.org/webnote/ - like Post-it
• Kiko - an online PIM
• Writely - Word Processor

An useful tool for who develops web pages. It’s a plugin for Internet Explorer (like Web Developer for Mozilla Firefox) that adds several features to the browser of Microsoft:

• Explore the DOM
• Validation of HTML, CSS, RSS
• Manage images
• Cache information
• Many other features

Silksite analyzes a web site with 120 tests in order to estimate of the aspects of marketing, design, accessibility, experience.

Mine is still too young, but the results are good (I’ll test it later):

• Marketing: How well marketed, and popular the website is. - 2.3
• Design: How well designed and built the website is. - 8.8
• Accessibility: How accessible the website is, particularly to those with disabilities. - 9.3
• Experience: How satisfying the website is likely to be. -7.4
• Visitor rating: Average user rating for this site’s design (website needs more votes) - No votes
• Overall: Summary score for this website. - 5.9

you can verify these results here.
