Snipplr is a website where you can store / share your code snippets and find the ones that are already shared by other users.
It is great to find real-world working code examples with an organized interface which saves a lot of time.
Snipplr covers almost every language from ASP, ASP.NET, PHP to Ruby, Django or AS3.

A feature I like is seeing the codes shared by a specific user (nice feature for following users whose coding style is much familiar to you).
Snipplr is absolutely a must-bookmark for a developer.
Convert HTML To ASP, PHP Or JSP? The title might seem fancier than the reality.
Response.Right is a web based tool which converts HTML into a variable (which is, probably, one of the top 10 hated tasks of a web developer).
This tool is very useful, for example, when creating a html mail that will be sent via a dynamic scripting language or converting large amounts of html that will be used inside these dynamic languages.

Supported programming languages:
- ASP - Javascript
- ASP - VBScript
- JSP
- PHP
Accessify.com offers some other free web based tools like Insta-Select (XHTML-compliant select list generator), Acrobot (converts all your acronyms/abbreviations using the <acronym> and <abbr> tag) & more.
