When someone submits a credit card number to your PHP Website, you can validate if the number has the correct format for each credit card company. The Modulus 10 calculation with a few checks can tell you which company issued the card, if the number is in the correct format, but not if there are funds on the card or if it is stolen. Reversing the mod10 calculations can create valid credit card numbers that can pass the mod10 checks, but without funds, they could only fool systems that approve cards by format and value without a back-end check at the bank.

Apple provides a JavaScript utility to generate the required tags to embed QuickTime content in a web page. Using this utility greatly simplifies the necessary code to embed a movie, as it automatically supplies such information as the QuickTime Class ID, code base, and plugins page. This has two main advantages over typing the tags manually: it requires much less code; and it works seamlessly with Internet Explorer for Windows, versions 6 and later, avoiding the “Click OK to enable ActiveX control” dialog box.

MX Record Configuration
Log on to your hosting provider or third-party domain name system manager.
Change your MX records to:
MX 0 = smtp.secureserver.net
MX 10 = mailstore1.secureserver.net

Domain-specific aliases are easier to remember:
CNAME mail.mydomain.com -> pop.secureserver.net or smtpout.secureserver.net
CNAME pop.mydomain.com -> pop.secureserver.net
CNAME smtp.mydomain.com -> smtpout.secureserver.net

POP (Incoming mail server)
Port: 110
Server: pop.secureserver.net
Username: your whole email address
SSL: Nope, that sucks unless you get certs

SMTP (outgoing mail server)
Port: 80 (Not the standard port 25!)
Server: smtpout.secureserver.net
Username: your whole email address
SSL: Nope, that sucks unless you get certs
SMTP must authenticate
You do not need to check mail before sending mail

For beginners in graphic design and computer graphics, the concepts of Image Resolution and Image Dimensions can be confusing. The notion that images have a resolution does not always correlate to the dimensions of the image at first, but the concepts are simple and the knowledge is quite necessary for graphic designers as well as PHP Programmers. The graphic designer needs to understand these concepts before starting a project, and the PHP Programmer must understand these concepts to apply automated image manipulation using PHP. (more…)

Software developers using Asynchronous Javascript and XML (AJAX) techniques to jazz up corporate Web sites are failing to pay attention to some very fundamental security issues, security researchers warned at the Black Hat USA conference in Las Vegas on Wednesday. As a result, many companies that have rushed to AJAX-enable their sites may be dangerously vulnerable to a variety of Web-based threats of which they’re not even aware. (more…)
