Windows XP, Format USB Drive – NTFS

By default Windows XP will only allow you to format your USB drive with the FAT or FAT32 file system. With a bit of tweeking you can format it with the NTFS File System.

An Intro to robots.txt

Intro

The robots.txt protocol also known as Robot Exclusion Standard or Robots Exclusion Protocol basically defines how web spiders and crawlers (search indexing tools) have access to your site.
The Web Administrator can Allow or Disallow access to certain parts of the site, e.g. temporary, private, cgi directories. It is a plain text file, where the rules for the these spiders, crawlers, where they can go and where not. You can also typically block a folder e.g. /images, because you find it both meaningless and a waste of your site’s bandwidth.

Syntax of robots.txt

# All comments is followed by a the pound sign
User-agent : [crawl agent name or * for all]
There are currently three statements you use in robots.txt

  1. Disallow: /path
  2. Allow: /path
  3. Sitemap: http://example.com/sitemap.xml

Note:

  • Crawl-delay: [a number that represent the time in seconds] is not a supported standard, but some bots do obey it.
  • Each crawler user agent section must be separated by a blank line.
  • Not all search engines respects some pattern matching. E.g. to block any directory name that begins with the name picture: Disallow: /picture*/
  • It is recommended if you use multiple User-agents, that the block of code addressed to all spiders (User-agent: *) is the last one. This is to reduce interpretation problems with some old robots.
  • Directives are case-sensitive. E.g. junk.html and Junk.html are seen as two different files.

User-agents

At User-Agents.Org is a very good list of these bots.
At the Web Robot’s page you can see a list of common robots – User-agent names.

Blocking

Blocking the entire site:
Disallow: /

Blocking a specific directory, images, and it’s contents:
Disallow: /images/

Blocking a specific file:
Disallow /junk.html

Blocking a specific file type:
Disallow: /*.xls$

Examples:

# Disallowing all robots

User-agent: *
Disallow: /

# Blocking only one robot, e.g. Altavista’s Scooter and allow all others

User-agent: Scooter
Disallow: /

User-agent: *
Disallow:

Now this is something we learned out of trial and error. In this example it looks like if we want to block MSNBot from a certain directory, and also disallow all other bots (including MSNBOT) from some more directories and give them, except for MSNBOT, access to the directory junk.
THIS DOES NOT WORK LIKE THAT!

User-agent: MSNBot
Disallow: /junk/

User-agent: *
Disallow: /cgi-bin/
Disallow: /private/

You need to disallow the directories for all the bots (User-agent: *) also for MSNBot!!! It should be:

User-agent: MSNBot
Disallow: /junk/
Disallow: /cgi-bin/
Disallow: /private/

User-agent: *
Disallow: /cgi-bin/
Disallow: /private/

Validation:

Here is a few sites, where you can validate your robots.txt file:

Happy coding 🙂

How To Hide Ads On Go-Daddy Free Site

If you have a Go-Daddy free-site this is how you can hide the advertisements to display in the browsers.
It is this simple!

Update your existing CSS files by adding the following code:
/*Hide Go-Daddy Ads on free-site*/
#conash3D0
{
display:none;
}

If you do not have an existing CSS file, it is quite easy to create.
Just follow these steps:

1. How to create a CSS (Cascading Style Sheet) File:

  • Open your favourite text editor.
  • Copy a paste the above code in it.
  • Save the file as, e.g. style.css
  • Upload the file to the root directory or a directory(folder) of your choice to your Web host.

2. How to link a CSS file in your existing Web Pages
Add the following code before the </head> tag in your existing pages.

  • If the CSS file is in the root directory:
    <link rel="stylesheet" href="/style.css" type="text/css" / >
  • If the CSS file is in the same directory as your Web Page:
    <link rel="stylesheet" href="style.css" type="text/css" / >
  • If the CSS file is in another directory, replace the words directoryName with the actual directory name:
    <link rel="stylesheet" href="/directoryName/style.css" type="text/css" / >

Remember to save or upload the files to your Web Host.
