Google AdSense Link Unit and a Strange Text box
I have Google adsense link unit on top of my blog just below its main title. And today something strange happened. When I opened my blog http://www.techsutram.com , found some strange text box, marked in red oval shape in above image. I have entered few words in this text box “What should I type in?” and pressed submit button “>>” and redirected to list of ads matching to submitted phrase.
I am bit concerned because it is disturbing overall look of my blog. Has anyone faced similar kind of issue?

Windows Search and Outlook emails
I am a big fan of Windows Search when it comes to Windows OS platform. My first and most favorite use case of windows search is finding emails quickly. I have inbox of over 15GB distributed across multiple achieves of .PST file (Microsoft Outlook). Of course, I am referring to searching emails (in Microsoft Outlook) from those 15GB+ emails.
Lets look at the example of how to find email from Mr. X and sent to Mr. Y and cc to Mr. Z with attachment and containing word “confidential” in its body or attachment.
In windows search box, it is enough to type in following query,
from:Mr. X toaddress:Mr. Y ccaddress:Mr. Z hasattachment:true confidential
That's it. Easy and effective.

Test Metric
A lot has been said and written about test metrics. However, this particular post will stick to defining test metric.
+ So what is Test Metric?
Test Metrics are set of tools that help measure effectiveness of software testing processes. Measuring software processes is necessary for implementation of new software processes and/or for improvement in current set of software testing processes in any organization. So in order to identify and use test metrics, we have to first identify and freeze on software testing processes that we would like to measure.
Can you think of any other definition of test metric? Then let everyone know in comments below.

HTML Vs HTML5
I was trying to understand basic differences of HTML5 against HTML (or HTML4 to be specific) and couldn't find exact information I was looking for. Hence I decided to compile it. Hope others will find it useful too.
| HTML | HTML5 |
| DOCTYPE is much longer as HTML4 is based on SGML-based. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" | DOCTYPE is required to enable standards mode for HTML documents. |
| Audio and Video are not part of HTML4 specification | Audio and Videos are integral part of HTML5 specifications e.g. <audio> and <video> tags |
| Vector Graphics is possible with the help of technologies such as VML, Silverlight, Flash etc. | Vector graphics is integral part of HTML5 e.g. SVG and canvas |
| It is almost impossible to get true GeoLocation of user browsing any website especially if it comes to mobile devices. | JS GeoLocation API in HTML5 helps identify location of user browsing any website (provided user allows it) |
| Browser cache can be used as temporary storage. | Application Cache, Web SQL database and Web storage is available as client side storage. Accessible using JavaScript interface in HTML5 compliant browsers. |
| Web Sockets are not available. Generally used mechanisms are long polling and streaming. | Full duplex communication channels can be established with Server using Web Sockets. Accessible using JavaScript interface in HTML5 compliant browsers. |
| Works with all old browsers | Most of modern browser have started supporting HTML5 specification e.g. Firefox, Mozilla, Opera, Chrome, Safari etc. |
| Does not allow JavaScript to run in browser. JS runs in same thread as browser interface. | Allows JavaScript to run in background. This is possible due to JS Web worker API in HTML5 |
I am not expert in HTML5 and neither in HTML4 specifications. These are just few set of differences in HTML Vs HTML5 that I compiled for immediate reference. I am absolutely sure that there is much more to add to above text. If you find anything wrong in above differences or if you want to add something to above differences of HTML Vs HTML5 then feel free to drop in your comments below.

It is employed by almost every popular site. It is implemented by all kinds of blogs, portals, and news sites and other. As said above, SEO forms essential part of SEM (Search Engine Marketing).

There are two kinds of SEO based on how they use different techniques to optimize web pages for search engines.
1. White Hat SEO – These are SEOs who use legitimate techniques as per search engine policies or guidelines.

What is Flaw?
Surprised to see title of this post! As you have guessed it correctly we are referring to Flaws in software. This is a small post just to differentiate Flaw from the Bug in software testing.
So what is Flaw?
Flaw is a similar to a Bug in a software till certain level. However, in my views, it is buried inside software design and gets implemented in code.
Do you have any other views for Flaw Vs Bug in software testing? then let everyone know in comments below.

Regression Testing ? Questions to ask before proceeding
There are numerous articles about regression testing available. However, most of them do not address essential points about regression testing. Here is my attempt to address that gap by asking few questions.
+ What is regression testing?
+ Why do we require regression testing?
+ What resources do we need?
+ How to justify the cost of regression testing?
+ What to test as a part of regression testing?
+ Do we require separate test plan for regression testing?
+ Does our regression test suite really address changes gone into the product?
+ How are we going to track defects identified out of regression testing?
+ Are performance tests are part of regression test suite?
+ What is the cycle of execution for regression test suite? And when do we start performing regression testing?
+ Are there any customizations possible to the regression test suite? If yes, how do you plan/document those customizations?
+ Have we certified the regression test suite before proceeding?
+ Who is going to certify the test suite for your product? Have we identified all stakeholders?
+ Where are we going to store results of regression test runs (in case your product has different releases)?
