Search a website or blog without search box

January 29th, 2009 admin

I was looking for a tool to search a blog since it did not have a search box.
So i Searched google but did’nt find any but surprisingly while searching i
came across a article in yourshortestpath which gave the answer and was
very simple.

Use Google To Search A Website or Blog Without A Search Box.

Steps to search a website or blog without search box:

* Go to Google search
* type the word you want to search space site:+”url of the site”

Example : dotnet site:http://fordevs.com

This returns the result with the pages having the word dotnet.

And to note the search returns only the pages indexed by google for that website/blog.

What is JSON?

January 12th, 2009 admin

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition – December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others.
