Why is software testing so critical? The answer is simple. Software bugs and errors are so widespread and so detrimental that they cost the US economy an estimated 0.6 percent of the gross domestic product. This amount approximately translates into a whopping $100 billion annually. Of this amount, half the costs are borne by the users and the other half by the software developers and software vendors. We must remember that nearly every business and industry in the United States depends on development, marketing, and after-sales support of software services and products. A study conducted by the Department of Commerce's National Institute of Standards and Technology (NIST) has assessed that more than a third of the costs can be eliminated by improved software investigating infrastructure consisting of a paraphernalia of testing tools for load testing, stress testing, and performance testing.
Many are not aware what software testing is all about. Countless people believe testing of software is high-tech jargon beyond easy comprehension. This perception unfortunately is a myth. In this electronic era, we need not be experts to be familiar with the basic concepts of software investigation. Understanding of the key features and advantages of software investigation helps a wide cross section of professionals and businesspersons in their day-to-day business. Here are answers to some basic question on software analysis.
What Is Software Testing?
In a nutshell, software testing is a process to recognize the accuracy, comprehensiveness, security, and quality of the developed software. In fact, it is a technical investigation intended to assess the quality-related information of the product for which it is planned to be used.
Different Web Testing Applications and Their Functions
The checklist of web testing applications is broad constituting many items. Here we shall deal with a few of them.
* Performance testing: A web application should sustain heavy workload, especially during peak times when many users access the same page simultaneously. In addition, the site must be able to handle input data from a large number of users simultaneously. A performance test also includes stress testing where the system is tested beyond its specification limits.
* Security testing: Security testing is done by various methods. One of the methods is by pasting internal URL directly in the browser address bar without logging in to ensure that the page does not open. Additionally, the product should use SSL for security measures. Web directories and files should not be accessible without the download option.
Most importantly, all error messages, login attempts, including security breach attempts, must get registered somewhere on web server.
What Is The Road Map To Higher Quality Software?
Software testing is a continually evolving process. Software investigating and evaluating companies are consistently striving to identify and remove software bugs. If all software bugs could be identified and removed in real time, the benefits to industry and business are huge and unquantifiable. Plenty of inadequacies are still plaguing the software market. Standardized testing tools must ensure a rigorous testing certification process. The road map to higher quality software is undoubtedly improved and foolproof software testing.

Important Data Recovery Tips
by: Holly Altman
File Recovery Services
Data recovery services can be an emergency situation. Of less importance of whether the device is repairable, the more concerning part is whether your important data, documents, and family pictures are able to be saved. All data recovery technicians and associated labs should be able to prove a consistent, reliable, and most of all industry trusted reputation.
Faulty Hard Drive
There can be two main reasons your data is in accessible - mechanical & non-mechanical. Mechanical failures are problems of the physical hard drive heads, platters, or even main board of the hard drive. For this there are two main services to perform. Firstly to repair the drive and try to get a read of the drive's contents. Secondly transfer the recovered data to a new drive. Non-Mechanical issues are usually whereby data has been corrupted, and/or there are bad sectors on the drive. Additionally other problems with the drive could lead to data access issues. For this repair type it I usual to attempt repair of the drive to a readable level, then start the recovery processes to obtain the drive's data.
Backup Software Tools
Current backups can be one of the most time and money saving assets when a data loss event happens. File recovery services can be mitigated with a recent backup and usually savings can be hundreds, and sometimes thousands of dollars with loss productivity and valuable documents. There exist many cloud (online) backup tools and also a simple USB portable hard drive can assist with some additional tools. If consistent changes are being completed on important documents it may not be convenient to keep a recent backup so consider arranging an Hotmail account and email the various dated versions to this account. This process will give you a dated archive as well as a current version in the case of a hard drive failure which can be ideal.
Estimated Recovery Prices
Generally a data recovery lab will be able to give you an idea of costs. A data recovery lab should be able to give you a general estimation of costs, or at least give an idea of what it could cost depending on what the issues are. Usually the cost is around $100-$250 for low level recoveries. $250-$700 for medium and upper level recoveries. With the top range of $700 and more for extensive damage to a drive and likely physical malfunctions of the hard drive itself. As always keep a back up to save you this expense and stress, and if you do have such a problem, call around to find a trusted repair centre in your area.

Storage Area Networks For Dummies
by: William Hauselberg
A Storage Area Network (SAN) is a collection of storage devices that are tied together via a high-speed network to create one large storage resource that can be accessed by multiple servers. SANs are typically used to store, share and access enterprise data in a more secure and efficient manner compared to traditional dedicated storage models. With dedicated storage, each server is equipped with, and uses an attached storage capability. A SAN meanwhile basically acts as a common, shared storage resource for multiple servers. The storage devices in a SAN can include disk arrays, tapes and optical jukeboxes all of which can be accessed and shared by all of the attached servers.
How a Storage Area Network Works
In a storage area network, the pooled storage resources and the servers that access this storage are separated by a layer of management software. The software allows IT administrators to centralize and manage multiple storage resources as if it were one consolidated resource. Because of the software, each of the servers sees just one storage device, while each of the storage devices in the SAN sees just one server. Data can be moved at will to any of the devices on a SAN.
Factors Driving SAN Adoption
A variety of factors have been driving enterprise adoption of SAN architectures over the past few years. One of the biggest factors has been increased cost-efficiencies. Storage area networks allow companies to optimize the utilization of their storage resources. With an attached storage disk, any extra storage capacity on that disk would remain unused because no other server could use it. With a SAN on the other hand, all memory resources are pooled, resulting in better usage of existing capacity. Since SAN�s allow data to be moved freely, enterprises can also move old and outdated data to inexpensive storage devices while freeing up the more costly devices for more important data.
Storage area networks make it easier for companies to expand their storage capacity, add resources on the fly, allot additional resources to an application, and maintain systems far more easily than traditional storage technologies. In addition, SANs allow companies to swap out a disk or tape-drive more easily and enable faster data replication. Importantly, SAN architectures allow storage devices from multiple vendors to be tied together into a common shared storage pool. Another advantage of SAN architectures is that they allow the storage network to be located at long distances away from the server hardware, thereby enabling greater disaster recoverability.
SAN Security a Big Concern
Despite such benefits, there are some caveats associated with the implementation of SAN architectures. Storage area network security is by far the biggest issue that companies need to do deal with when moving to a SAN storage model. With a SAN, companies are literally putting all of their most important data in one central resource. As a result the need for security controls such as firewalls, intrusion detection systems, SAN encryption and network monitoring are greatly heightened.

How To Resolve System Table Mismatch Error In SQL Server
by: Mark Willium
In Microsoft SQL database, there is some value (data) in the metadata structure that describe each and every table. These values change due to metadata corruption that can result in inaccessibility of data saved in the SQL Server table. Some causes for metadata structure corruption are SQL database damage, mallware function, power failure and human errors. Once the table is damaged, an error pops up describing the cause for the corruption. To surpass the error and to access the SQL database table records, you need to restore the records from an updates and latest backup. However, if in case, the latest backup fails to restore the desired records, then you will need to use an advanced SQL recovery application to repair the damaged table.
Consider a scenario, wherein the below error message pops up when you attempt to access a SQL database table:
System table mismatch: Table 'O_NAME' object ID O_ID has index id 1 in sysindexes but the status in sysobjects does not have the clustered bit set. The table will be checked as a heap.
Since the error message appears while trying to read the records of SQL table, the records saved in the table become inaccessible mode.
Root cause of corruption:
The above error message occurs when the metadata structure describing the table gets corrupted.
Way to solve:
For resolving above error message you can follow provided steps below:
To resolve the SQL table error, if caused due to physical corruption of a system component, you will need to change the damaged system with a new one.
The above error message, if caused due to logical corruption, you can be resolved by running DBCC CHECKDB command with correct repair clause. However, if the above error persists even after running the repair command, then you will need to opt for SQL repair tool for repairing the table.
Stellar Phoenix SQL Recovery is an MDF file repair software that is able to repair .MDF files from all instances of corruption.

Proxy Site and how it Works
by: Farrukh baig
A proxy site is a web page that enables you to surf your favorite web sites even if your access to such web sites might be blocked by some content filter, for instance Web Sense (site name) or Smart Filter. Using such proxy site will keep your visit to those sites hidden so the content filter will not know that it was unsuccessful in blocking that visit.
So how do these sites work? In this short article we will explain...
Proxy sites allow you to browse blocked websites through proxy site bypassing the internet service provider. Proxy site do that by providing its user to key in the address of that website and be directed to the page in a window in that vary site. Now the advantage here is that this window is coded as the proxy site address and not the actual site address that the user is visiting. Also the information caught in the temporary internet files will appear as the related to the proxy site not the blocked web page.
So how these sites do are blocked in the first place. Web sites are blocked using a number of programs in particular the security software. These software works with the web browsers which let users to surf World Wide Web. Now days many web browsers are coming up with their own filters which keep the blocked content from appearing. In local area networks the system administrator can also block web sites on that network level. Ninja Proxy, Ninjaproxy and Vtunnel!!! Ninja Proxy is a free browser based anonymous proxy service.
So why should one run a free proxy site one guesses but if you look the financial aspects of such service. It’s because they are very simple to advertise and one can earn up to 10$ a day. But on the other hand the cost includes a server that would allow the proxy to run on them as using a shared host would not be able to hand the web traffic and go down in days. But still when you are managing web traffic through your proxy site the earning much more then any other ordinary web page.
The question come then what you need to run a proxy site. You would need a domain name, a virtual private server, proxy script like PHP proxy and last you would add an adsense (or your own name) and adbrite (or your own name) account. When you got the domain and virtual private server you need to download the script on to your virtual private server make the necessary configurations and upload the script. When you have register for an adsense (or your own name) and adbrite (or your own name) account then insert adsense in your index page and adrite on proxy pages. Do not insert adsense on the proxy pages because it’s against the terms of the use. And last Advertise more and more.
I’ve read several news articles about proxies and how they are being used by hackers all over the world, some employed by foreign governments, to get into millions of computer systems around the world. The goal is to create what they call a boot net which allows them to use all these computers to do all sorts of nefarious things from the safety of these millions of computers. All of this activity then points to the owners of the computers through their IP address and ISP.

Computer and Internet Privacy Basics
by: Anna Sonen
The Computer Privacy protection is a very serious issue to be ignored these days."Everything you do online and offline is monitored by someone.", say many people out there and they are right not because of their paranoia but because the Private Information is too valued for its owner. But is it possible to protect our Computer Privacy without plugging the cable?
See how somebody could steal your Private Information. Reveal what is the difference between Computer Privacy and Internet Privacy. Read how to generate Secure Passwords that hackers can not break.
1. What is Computer Privacy?
This is the power to control what computer information you reveal about yourself and to control who can access this personal information.
2. What is Internet Privacy?
It is a part of the computer privacy. It is the power to control what information you reveal about yourself in Internet, the power to control which web sites, remote scripts and web applications can access this personal information, and the power to know if these web sites, scripts, and web applications are enough trustworthy.
3. What is Private Information?
No doubt, your computer keeps tons of information about:
* all web sites you have visited
* all documents, folders, pictures, videos, files you have opened and created
* all e-mail, forum names and passwords you have
* all bank and credit card information you have saved
* all Skype-to-Skype calls and ICQ chats you have made
* all technology, writing or art you have invented
* your online shopping activities: when you visit the online store order page of some web site
* your shared photos, videos, age data, hobbies, preferences, even thoughts with everyone out there
* generally all your computer habits and things-to-do
All computer and web data you consider to private is your private information.
4. How to Generate Secure Passwords that Hackers can not break?
We use passwords every day to access our computer accounts, e-mail accounts, bank accounts, Facebook and Twitter accounts and hundreds of other services. There is great temptation to use one password for all accounts and to make it short and easy to remember. However, this has devastating effect on our security and privacy. If you think that you have nothing to hide, think again.
In most cases the passwords are hacked to use your computer as spam bot, to steal your money and private information, to infect your computer with computer viruses and spyware and so on.
Learn to avoid the following weak and easy to crack passwords:
* Generic passwords and default passwords. Examples: admin, administrator, user, guest, pass, password, iloveyou, 2010, etc. These are the first passwords that are tried by the password cracking software.
* Meaningful words or names. Examples: sandbox, NY, lion, john, mary, USA, love, myspouse, dragon, etc. Easily cracked by the dictionary-assisted cracking tools.
* Words or names with added numbers. Examples: john123, pass123, 123456, number1, abc123, 654321, etc. Easily cracked by the automated cracking tools.
* Personal names, birthdates or similar information. These are used a lot as passwords and are very easily cracked. For example, if the password is a birthday, there are only hundreds or few thousands (if the year is included) possible combinations, which is very weak for a password.
Learn to generate strong random passwords through these rules:
* Choosing "randomly" letters and numbers. It appears random but only at first sight. Numerous research studies have proven that humans are not very good at random picks - they always try to spread the things too evenly, which is not random behavior.
* "Random" typing on the keyboard with closed eyes. This is slightly better than random choosing but still nowhere random enough.
* Online random password generators. Much better than the previous two alternatives but have 2 major drawbacks. The first is the possibility that the generated password may be saved on the website with malicious purposes or someone may eavesdrop on your connection and intercept the generated passwords. The second major problem is the quality of the random number generators, which very often is not up to the task. Many of them are naively implemented and provide a lot fewer combinations than theoretically possible (no more that tens or hundreds of millions, which is not strong password by any means - see the table in the previous chapter).
* Specialized random password generator programs. The best option as long as they are implemented properly and come from trusted source.

* "Random" typing on the keyboard with closed eyes. This is slightly better than random choosing but still nowhere random enough.
* Online random password generators. Much better than the previous two alternatives but have 2 major drawbacks. The first is the possibility that the generated password may be saved on the website with malicious purposes or someone may eavesdrop on your connection and intercept the generated passwords. The second major problem is the quality of the random number generators, which very often is not up to the task. Many of them are naively implemented and provide a lot fewer combinations than theoretically possible (no more that tens or hundreds of millions, which is not strong password by any means - see the table in the previous chapter).
* Specialized random password generator programs. The best option as long as they are implemented properly and come from trusted source.
