Anonymous is everywhere.
Anonymous has no identity.
Anonymous is an unstoppable force.
Anonymous doesn’t fall in battle, anyway.

These are all some famous quotes about anonymous , lets get into our topic . Anonymous browsing or Proxy Surfing  is simply browsing the World Wide Web with most of your identity hidden. Proxy surfing is necessary for two cases

1. Securing Information
2. Freedom to browse all websites from Internet

Why do we need it?
Case 1 : Securing Information
If you are connected with network or Internet , your computer or network device will be assigned by one unique IP address , using that address only the computers can transfer the data from one to another and also all information might be collected such as your location , packets information, personal data. so we need to protect our data.

Case 2: Freedom to browse all websites from Internet
In college or school , Management will use proxy server to ban some websites for security purpose. Its necessary to prevent student to browse an inappropriate websites but due to this they cannot surf all the information from Internet. Some times the proxy server will block some important websites. Internet is like a universe , There would be good and bad things in it . You are the responsible person to collect the information based on your need.so freedom for browsing is needed for this case.

How to do it ?
User can install proxy software to browse all information from Internet . In our case lets take Ubuntu Linux for installing tor.  The following software are needed for proxy surfing in Ubuntu Linux Operating System .

1. tor  – The Online Router
2. privoxy -  A web based program often used with tor
3. torbutton  – Firefox add-on for tor

The tor package using socks 5 connection which is specially used for proxy server communication . You can install these packages using synaptic package manager in Ubuntu or manually download the following files and just click on it

• Libc6
• Lib Event
• Tsocks
• Tor
• privoxy
• torbutton-1.2.2-fx

After installing these packages, Just open the Firefox and enable the tor button which would be in bottom-left corner. If you are using some other browser like Opera then manually assign the Ip address in Network Option .

Tor manual IP

Finally We need to add two lines in privoxy config file . Goto  /etc/ptivoxy/config file in root mode

#sudo su

#gedit /etc/privoxy/config

In section 4.1 add the following line

Your-IP-address :8118

In my case

192.168.34.23:8118

Add the following at end of the config file

forward-socks4a / localhost:9050 .

Note : Space and dot also very important , do not mistype anything . I have attached sample configuration file for your reference

Click hete to download sample privoxy config file

Enjoy the freedom of browsing the INTERNET …..

I’ve listed 5 of the best apps to hide, resize and do some funky stuff like translucency, all in the name of productivity. Check them
out:

1. KDE Window Resizer

One of the things I absolutely adore in KDE Window Resizer is how they handle window resizing and moving. You simply hold down the ALT key, just about grab the window from anywhere and you can move the window around. No need to grab the title bar. Perfect for situations  when the title bar is off screen due to change in screen resolution. To resize the window, just hold the ALT key and click and drag the right mouse button and the window starts resizing according to the movement.

2. Window Hider

Window Hider is a simple application that you can use for managing the open windows. It does two things – it can hide the window you want  by simply moving your mouse cursor to the corner or it can kill the application you specify.

You can give Window Hider a list of programs and a shortcut key then when you press that shortcut key it hides only those windows in your list. You can also activate hot corners on screen which hides all the programs in your list by simply moving the mouse cursor to the hot corner. Pretty cool.

3. Desk TopMost

So you have a lot of open windows? And you want to access the desktop icons? You could hit Win+D, but then you wouldn’t be able to return to the windows as they were opened, you would have restore the window from the taskbar yourself. Windows7 and Aero peek does an excellent job of it. In case you are not using Windows 7 or your computer doesn’t support the slick Aero Peek, you should try Desk Topmost. Just hit Ctrl + Alt + D and it provides you with a translucent overlay of your desktop over the open windows. After you are done, just right click anywhere and its gone.

4. Power Resizer

Allows you to mimic another one of the Windows 7 features, power resizer neatly fits your open windows to half screens or maximises them as you drag them to a screen edge or to the top of the screen. Simon covered it earlier here.

5. WindowTabs

WindowTabs attaches a small tab to the top of your windows. You can then drag tabs on top of each other to group them into tabbed windows. Use Alt + Right Arrow and Alt + Left Arrow to cycle through the tabs. Clicking on the tab with your mouse cursor willl take you to the tab as well. The application has a trial and a full version. While the trial version doesn’t have any time limits or nag screens, you would be limited to 3 tabs per group, which is not so bad of a deal.

How did those apps help you with your cluttered screen? Know of any more applications that fit the criteria? Or perhaps better alternatives to the above? Let’s hear about them in the comments.

Method 1

a^2 – b^2 = (a+b) (a-b)               ——-          Eqn 1

a^2 – a^2 = (a+a) (a-a)               ——-          Eqn 2

a^2 – a^2 = a (a-a)                      ——-          Eqn 3

Equate 2 and 3

a (a-a)  = (a+a) (a-a)

=>  a = (a+a)

If a =1 then 1 = (1+1)

=>   1 = 2  (Proved)

Method 2

If a^m = b^n then

m =n

1^0 = 1^1

=> 0 = 1

Add one on both sides

0+1 = 1+1

=> 1 = 2 (Proved)

With the move to host your own blog comes many complications and many more liberties. This article will discuss some of the free and open source wordpress plugins every wordpress blog should have.

The top WP plugins

WP Captcha Free

Comment spam is the bane of the blogging world. The problem was so severe on my blog that I had to use an SQL query to delete the database! Not everyone can do that or spend dozens of hours deleting spam comments.

The Akismet plugin that comes with the wordpress installation has been known to get over-zealous and mark a legitimate comment as spam. Personally I am not a big fan of ugly looking CAPTCHAs at the bottom of the comment form either.

To put it simply it uses javascript code to report to the server that the person sending this comment is a real human being. This is important and the reason this plugin is better than the others because comment bots cannot run javascript. So they will not be able to report to the server authenticating their comment. This places no burder on the commenter asking them to enter the result of 2 + 2 or what looks like ‘wAKle2′ in a text box.

All In One SEO Pack

This plugin adds many input fields in your administration panel to customize the HTML meta tag’s  keywords, description and title of each page of the web page. This will help search engines to better understand the content of the page.

When a user sees your web page among the various pages in your search results, you are competing with the 9 other pages for attention. The best way to improve the chances of your page getting the click is by being more relevant to the purpose of the user. The searcher judges the relevance of your article from the brief text they see below the link to your web page.  They do this in a fraction of a second.

If there isn’t any meta description tag, Google displays a random excerpt from your page which is only probably relevant to the searcher. So to get more search traffic customizing the meta keywords and meta description of each blog post is important. WordPress doesn’t provide the facilities to customize these attributes by default. Thats where this plugin comes to your rescue.

Contact Form 7

Many bloggers make it incredibly difficult to collaborate with them. Blogging doesn’t happen in a vaccum. You need to work with other bloggers of the same topic to become successful. This involves guest posting opportunities or product promotion opportunities. How can these come your way if you don’t make it easy to contact them. This can also be used to make yourself available to your readers.

Where did they go from here

This is the blogging equivalent of Amazon’s “Customers who bought this also bought…”. It adds a section of links at the bottom of your blog post (not the home page that lists the blog posts) that point to similar blog posts you have blogged. Good way to keep visitors on your blog.

Google Analyticator

This plugin allows you to add Google analytics to your website without having to edit the wordpress theme. This saves you the effort when you have to change the wordpress theme for some reason.

Google XML Sitemaps

This plugin, as the name implies, creates a XML sitemap to submit to Google  Webmaster Tools. Even pages that are not directly linked will be crawled easily.

Wp DB Backup

Your website with all of its posts can disappear because of a crash on your hosting server. This post specify a backup frequency. The entire mysql database is backed up and is either saved to your server, sent as an email to you or download it on demand.

Add To Any

This plugin adds a small chicklet to allow users to add your post to social bookmarking and social networking websites. This is essential to get social media traffic to your blog.

1. Email ID limited to 100
2. Sub Domains are limited to 1000
3. Storage Space is only 5GB [ Based on Request , This may be increased ! ]
4. We can not create permanent links for our post when we use blogging softwares  like Word press
5. No Access for .htaccess file  [ So we can't install Drupal in Yahoo small business ]
6. No SSH [ Secure Shell ] Service

I could not find any alternate solution for SSH service  and .htaccess file . but i found one solution for permanent link which is useful for search engine optimisation . Lets get in to the problem first . When you use word press software , By default each and every post will be represented by numbered link.

For Example  :   http://www.rajarajan.in/?p=10

http://www.pradeepkumar.org/?p=362

These links are not indexed properly while search engines crawl your site. You need to assign proper name for every posts . you can follow the following standard procedure for assigning name for your post

Naming Post Links [Click Image To Enlarge

1. Day and name     http://www.openpeta.com/2009/05/25/sample-post/
2. Month and name     http://www.openpeta.com/2009/05/sample-post/
3. Numeric     http://www.openpeta.com/archives/123
4. Custom Structure

Here the problem is coming ,  when you change default to other in word press , The links will not work because of .htaccess problem with Yahoo small Business. But you can do one alternate thing to assign the permanent link to your posts. Just add index.php after the main url  or link.

Custom Permanent Links [Click Image To Enlarge

1. Day and name     http://www.openpeta.com/index.php/2009/05/25/sample-post/
2. Month and name     http://www.openpeta.com/index.php/2009/05/sample-post/
3. Numeric     http://www.openpeta.com/index.php/archives/123
4. Custom Structure   /index.php/%postname%/

Then all links  will work properly , If you find some solutions to these problems , please post your solutions through comments of this page.

Get this Firefox Extension From https://addons.mozilla.org/en-US/firefox/addon/1730

Then came Gmail – the most spectacular AJAX application that showed everyone what can be done if you use the XMLHTTPRequest object in the various browsers. This made it easier for both the web application developers and the users. Javascript frameworks were created and user interface libraries created to facilitate developing web applications based on this tool.

As web applications got more and more complex, these libraries could not keep up with the demand of better user interface widgets and a more flexible API.

While all this was happening Macromedia, now Adobe has been working on Adobe Flex. Until recently only enterprise users were able to create UIs  in this fabulous platform. But Adobe (which acquired Macromedia) released the SDK as an open source project.

This article will discuss all the reasons why your application should use Adobe Flex for creating the user interface:

1. Flex Is Easier To Develop Than Javascript

The programming in Flex is done using Actionscript. This language is 90% similar to javascript. If you know Javascript, its only a matter of knowing the differences and adopting the object oriented mindset to get started coding in Flex.

Actionscript is extremely similar to Java in that it supports inheritance, private variables, packages and interfaces.

2. Binding Is Much Simpler

This one feature is sure to appeal to many developers. If you want to detect the change in some variable  or the value of a text box, perhaps to do some validation, it takes dozens of lines of code in Javascript but it is done automatically from the MXML markup. With javascript, you would have to manually create the div element that showed the error message and manually enter the error message using innerHTML.

3. Leverage Actionscript Lirbaries

There are numerous actionscript libraries that are available for performing operations that are not available in Javascript. Actionscript libraries exist for performing complex encryption and even manipulating images! Something that cannot be done in Javascript. I suspect Pixlr is a flex application

4. Complex Widgets

HTML wasn’t meant to create the interfaces of applications. It was meant for displaying styled documents. Embedding such widgets as DataGrid requires you to define the widget in terms of a lot of markup and hundreds of lines of javascript code to add the necessary behavior and style.

Actionscript however comes with pre-built advanced interfaces such as Accordions, Tabs, Tab Bars, Menus, Context menus, form items and stacked widgets. With flex it would be possible to make web applications feel like desktop applications.

5. Porting To  Adobe AIR Is Trivial

If you have created your application to work on the browser, then the same code can be easily turned into a desktop application with the exact same interface. The best part is the application will run in Windows, Macintosh and Linux with the native look and feel.

Tip: the default look and feel of the flex applications can quickly get boring. Go to Scale9 to get style sheets and flex skins. This will give each of your projects a unique look and feel.
