Unlock any iPhone in minutes!
2009-03-30 10:00:00
A couple of weeks back while on a conversation with a friend from CA, she expressed concern over how it was ridiculous for Apple to lock its iPhone only to be used by AT&T network! She was looking for a possibility if she could ever unlock her Apple iPhone 3G and be able to use it with other networks. I was searching over the net for any such resources and came upon this excellent looking website

Why is most software so bad?
2007-02-03 15:41:00
(from an interview with Bjarne Soustroup in techreview.com) Technology Review: Why is most software so bad? Bjarne Stroustrup: Some software is actually pretty good by any standards. Think of the Mars Rovers, Google, and the Human Genome Project. That's quality software! Fifteen years ago, most people, and especially most experts, would have said each of those examples was impossible. Our

Software Quality and Testing
2007-01-28 15:36:00
From: New Earth Online Testing is one of the fundamentals of Quality Assurance, it outlines where the defects are in a measurable form and helps to make an application "bug free". Remember though that software testing never reveals the absence of bugs, only the presence of them. The purpose of this guide is to help promote the ideals of software quality, and illustrate why it is a good thing.

Performance, Reliability and Security Testing
2007-01-23 12:46:00
Performance testing: Not all software systems have specifications on performance explicitly. But every system will have implicit performance requirements. The software should not take infinite time or infinite resource to execute. "Performance bugs" sometimes are used to refer to those design problems in software that cause the system performance to degrade. Performance has always been a great

Software Bug Tracking : Who Is Responsible?
2007-01-17 09:37:00
From: Soft ware Projects.org Bug tracking. It's the Achilles' heel of software development. It's easy to report bugs found in software, but unless the bugs are properly tracked, all the way through to their resolution, one can never be sure whether these nuances truly have been swatted. Like criminals on the run, without proper bug tracking procedures, those responsible for fixing bugs spend their

I hope you all know about Google Suggest. It as a search interface of GOOGLE, where possible keywords are suggested to you as you keep entering your keyword. Cool feature, right? Google does it by the help of Ajax. It helps the user to narrow down his/her search item based on the suggestions. Check it at: http://www.google.com/webhp?complete=1&am p;hl=en Today I was using it, when I noticed this 'BUG'. Steps to Reproduce the Bug:1. Open Google Suggest (http://www.google.com/webhp?complete=1&a mp;hl=en).2. Enter any keyword3. At any stage enter 'back-slash' () in the keyword field.4. You will get a script error.

Software Errors: Prevention and Detection
2007-01-12 06:55:01
FROM: Mactech ArticlesMost programmers are rather cavalier about controlling the quality of the software they write. They bang out some code, run it through some fairly obvious ad hoc tests, and if it seems okay, they're done. While this approach may work all right for small, personal programs, it doesn't cut the mustard for professional software development. Modern software engineering practices include considerable effort directed toward software quality assurance and testing. The idea, of course, is to produce completed software systems that have a high probability of satisfying the customer's needs.There are two ways to deliver software free of errors. The first is to prevent the introduction of errors in the first place. And the second is to identify the bugs lurking in your code, seek them out, and destroy them. Obviously, the first method is superior. A big part of software quality comes from doing a good job of defining the requirements for the system you're building and...

Test Bed Vs. Test Data
2007-01-02 12:46:02
Test Bed is an execution environment configured for software testing. It consists of specific hardware, network topology, Operating System, configuration of the product to be under test, system software and other applications. The Test Plan for a project should be developed from the test beds to be used.Test Data is that run through a computer program to test the software. Test data can be used to test the compliance with effective controls in the software.

Agile Testing - The BUZZ !
2007-01-02 12:46:02
Agile testing is the new buzz word in testing industy. Testing from beginning of the project and continually testing throughout the product lifecycle is basis of agile testing. If tester can work with client and help him specify the requirements in form of test cases then it makes tham completely unambiguous. So the test cases are ready even before coding starts so developers can start measuring the progress of development using the number of passed test cases. Agile testing is an iterative process wherein there will be constant interaction between developers, testers and clients."Giving the test cases to developers even before coding starts", sounds cool but some testers are skeptical that developers might be writing the code just to pass the given test cases !!!. Well, alternately if testers comes out with all the test cases possible then developer will end up writing code that will handle all the test cases. In traditional testing, the testing team competes with development team ...

How to handle Late Requirements !
2007-01-02 12:46:02
Many of project issues are related to bad requirements management. One particular issue which is hard to tackle is the handling of late requirements.Coping with new requirements after the development has started often leads to problems in the project:1. schedule, cost and scope of the running project become unknown2. delays due to unsufficient impact investigation, which may propagate to other projects in the program.3. rework of finished development4. quality problems, unsufficient time left for testing5. lost accountability of the development team6. drifting moraleBefore starting with the implementation of late requirement, do a feasability study including an impact analysis on the cost, schedule, and scope of the project.The following alternative solutions can be offered for development to handle the late requirements:1. Define a separate update release for the late requirements2. Leave room in the original plan to handle late requirements3. Prioritise requirements, leave some pr...

Bug Priority Vs. Bug Severity !
2007-01-02 12:46:02
Differentiate Priority and Severity. The effect of a bug on the software does not automatically correlate with the priority for fixing it. A severe bug that crashes the software only once in a blue moon for 1% of the users is lower priority than a mishandled error condition resulting in the need to re-enter a portion of the input for every user every time. Therefore, track priority and severity separately, then triage appropriately. It helps to have input from others on the team on priority. The importance of a bug is a project decision, different from the bug's perception by the Customer. In some cases it makes sense to track Urgency, the customer's point of view, separately. Microsoft uses a four-point scale to describe severity of bugs. Sev 1 is a crash or anything that loses persistent data , i.e., messing up your files on disk. Sev 2 is a feature that doesn't work. Sev 3 is an aspect of a feature that doesn't work. Sev 4 is for purely cosmetic problems, misspellings in dial...

Software Test Automation - Facts (Realities) and Fictions (M
2006-12-12 12:32:01
Test automation is a gimmick, most QA/Test managers use, to divert attention from serious issues of a project. This is what I have realised about test automation in all these years. Believe me, I am saying this from my past experience. If you are also in software testing/QA field then you might have noticed this too. Whenever a projects fails to meet its deadline or it fails to meet the expected quality, then only test automation is considered as an option. As if by using this magic bullet, we could attain quality over night ! As the requirements keep changing (mostly new requirements are getting introduced on daily basis) constantly and the testing window is getting smaller and smaller everyday, the managers are realizing a greater need for test automation. This is good news for us (people who do test automation). But, I am afraid this is the only good news.Myths & Facts A number of articles and books are written on different aspects of Software Test Auto mation. "Test Automation...

Common Misconceptions about Software Testing
2006-12-08 06:28:01
From the Book: Global Software Test Automation: A Discussion of Software Testing for ExecutivesThere are many misconceptions about software testing. This article deals with the five most common misconceptions about how software testing differs from other testing.Five Common Misc onceptionsSome of the most common misconceptions about software testing relate to how software testing differs from other testing. Following is a discussion of the five most common misconceptions about software testing:1. You can completely test the system. If you stop to think about the enormity of accomplishing such a task, you will quickly come to realize that it is not possible to completely test any complex software system. First you start with the complexity of the software under test. Layer upon this the complexity of the numerous combinations of data and user input. Add to this the complexity of the countless combinations of computer hardware, system software, network software, and other software that...

1. When you get a resume for interview from your HR Manager, go through the resume and check with yourself whether you can interview such a profile you have recieved and also do let your manager know your comfort level to interview the candidate based on the technical skills of your and of your candidate. 2. Every question you ask, should be towards the objective of revealing how fit the skill of the candidate, is towards the opening you have. 3. Do not ask too much about theory on testing, no two people know the same definition. And in the world of testing, there is no fixed definition for any technical term !4. Have a discussion (not rapid fire questions) and or try to test something with the candidate and see how his/her approach and thought process is towards the testing. 5. Do not ask questions that do not have a standard answer in this world, like - What is the difference between Sanity and Smoke testing? - rather it would be challenging for the candidate, if you ask - If you ...

The Cost of Quality is the Cost of Bugs !
2006-12-06 18:26:01
The first graphic projected on the overhead screen in a QA Class shows a rising curved line representing the cost of finding a bug as the project proceeds. That is, bugs caught during the requirements phase are much less costly than bugs caught during the design phase, the ones identified during the design phase cost less than those caught during coding, and bugs caught during coding cost less than bugs identified during test. The big no-no is to let bugs get caught after delivery. The cost of these bugs is huge, and many a creative graphic artist has depicted this fact by making the bugs larger in the later phases of development.I have a problem with this graphic. I think it is original intent was to dramatize the necessity of front-loading the development effort, i.e., not skimping when it comes to doing requirements analysis or program design. The problem is that this graphic is now used to downplay the importance of system testing and the subject matter expertise needed to do it...
