Many factors go into the security of a Web site, particularly an e-commerce one. While creating a secure Web application in the first place is a key component, there's an easy way to improve the security of a site over time: by maintaining secure passwords. In this post, I'll explain what this means.
A feature of many of today's Web sites is the ability for users to upload files to the server. While often necessary, this process presents a new type of risk to servers and sites, whether any user can upload a file or just an administrator can. In this post, I explain what steps you can take to limit the risks of allowing for file uploads.
The bulk of security-related advice is based upon preventing break-ins, hacks, and attacks, but responsible e-commerce developers and administrators know that it's just as important to have created an emergency plan well before trouble occurs. In this post, Larry Ullman talks about why an emergency plan is important and what, exactly, that means.
The security of an e-commerce site depends upon so many things: the hosting involved, keeping all the software updated, using secure passwords, and so forth. But when it comes to the software you write--the Web application itself--the most fundamental security concept is that incoming data is validated, validated, and validated. In this post, Larry Ullman writes about what that means, from the concept to the implementation.
Working with text in Flex 4 has changed significantly thanks to support for the Text Layout Framework (TLF). In this post you'll learn what the TLF is, what it does, and how you use it.
Application effects are, of course, nothing more than eye candy, but I think we can all admit that a little eye candy here and there is nothing to be ashamed of. Certainly the folks at Adobe think so, as they upped the effects library in Flex 4. In this post, I discuss the current state of effects in Flex, and how you use them.
One of the tricks to Rich Internet Applications is getting them to handle standard user requests in the same way as basic Web pages. One such issue involves making a Flash application respond appropriately when the user uses the back and forward buttons, the browser history, and their bookmarks. I'll tell you exactly how to do that in this post.
View states provide the Flex developer an easy way to adjust the look and behavior of a Flash application on the fly, normally in response to some user actions. How view states are created and used have changed in Flex 4, for the better. In this post, you'll learn everything you need to know to add view states to your Flex applications.
If, like me, you believe that data is the key to a great Rich Internet Application, then the Data/Services tools built into Flash Builder are for you! Check out this post to learn how the new Data/Services panel will help you develop a bug-free client-server application in no time.
The Flash Builder IDE is a powerful tool, making Flex development that much easier. You can streamline your development process even more by taking a peek into the application's Preferences panels to customize its behavior to suit your style. One tweak that will pay off immediately is to edit the file templates, as I'll explain here.
A wonderful addition to Flash Builder is its Network Monitor, a tool for detailed reporting of all Flex-server communications. The Network Monitor can be used to test, debug, and improve the use of Web services in your Flex applications. You'll learn everything you need to know about this valuable new tool in this post.
