  • Do You Know ? AMD Bulldozer

    AMD Bulldozer

    AMD’s new Bulldozer processors are finally here. This is AMD’s attempt at making an architecture with significant multi-threaded performance but at a price which most people can afford. Many believe that AMD’s last “great” architecture arrived back in the Socket 754 / 939 days when the Athlon 64 processors found themselves competing against and in many ways beating the Pentium 4 black and blue. In those days names like Clawhammer, Sledgehammer, Newcastle and San Diego came to the forefront but [...]

    Encrypting Data with Mcrypt

    MD5 hashes work just fine if you never need to see your data in readable form. Unfortunately, that’s not always an option—if you offer to store someone’s credit card information in encrypted format, you need to decrypt it at some later point. One of the easiest solutions is the Mcrypt module, an add-in for PHP that allows high-grade encryption. The Mcrypt library offers more than 30 ciphers to use in encryption and the possibility of a passphrase that ensures that [...]

    Protecting Data with a One-Way Hash

    This script performs a one-way transformation on data—in other words, it can make a hash signature of someone’s password, but you can’t ever decrypt it and go back to the original password. Why would you want to do that? The application is in storing passwords. An administrator doesn’t need to know users’ passwords—in fact, it’s a good idea that only the user knows his or her password. The system (and the system alone) should be able to identify a correct [...]

    Using SafeHTML

    The problem with the previous script is that it is simple, and it does not allow for any kind of user markup. Unfortunately, there are hundreds of ways to try to sneak JavaScript past someone’s filters, and short of stripping all HTML from someone’s input, there’s no way of stopping it. Currently, there’s no single script that’s guaranteed to be unbreakable, though there are some that are better than most. As you’ll learn in more detail in “Verification Strategies” on [...]

    Preventing Basic XSS Attacks

    XSS stands for cross-site scripting. Unlike most attacks, this exploit works on the client side. The most basic form of XSS is to put some JavaScript in user-submitted content to steal the data in a user’s cookie. Since most sites use cookies and sessions to identify visitors, the stolen data can then be used to impersonate that user—which is deeply troublesome when it’s a typical user account, and downright disastrous if it’s the administrative account. If you don’t use cookies [...]

    PHP security – How to secure your website from sql injection attack

    Because the queries that PHP passes to MySQL databases are engrossed in the regnant SQL programing module, you run the try of someone attempting an SQL injection onset by using MySQL in web query parameters. By inserting despiteful SQL encrypt fragments into grade parameters, an wrongdoer attempts to delapidate into (or disable) your server. Let’s say that you have a form parameter that you eventually place into a variable named $product, and you create some SQL like this: $sql = [...]

    Sony HDR-PJ50 camcorder with built-in projector and hard-drive

                    Sony’s Handycam HDR-PJ50 should make recording and playback of videos a much easier affair with its built-in hard-drive, projector and stereo speakers. The camcorder’s built-in projector can display videos that measure 60-inches diagonally when the projection surface is at a distance of three meters. The built-in stereo speakers can playback sound with which Sony claims are “powerful” should make for a fairly decent playback experience. These cams are retailing in India for [...]
