By Larry UllmanFeb 25, 2011

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.

By Larry UllmanFeb 24, 2011

A feature of many of today's Web sites is the ability for users to upload files to the server.

In this post, I explain what steps you can take to limit the risks of allowing for file uploads.

In this post, Larry Ullman talks about why an emergency plan is important and what, exactly, that means.

Validate, Validate, Validate: Five Critical E-Commerce Security Tips in Five Days

By Larry UllmanFeb 22, 2011

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.

Understand Your Hosting, Five Critical E-Commerce Security Tips in Five Days

By Larry UllmanFeb 21, 2011

People often think that the security of an e-commerce site is primarily based upon the software they write. Although the Web application itself must also be secure, the biggest factor, in my opinion, is the Web hosting being used. In this post, you'll see why hosting is such a critical consideration, as well as what additional steps one might take depending upon the hosting involved.

Choosing the Right Color Value

By Jason Cranford TeagueDec 14, 2009

Q: Should I use Hex or RGB values to define colors in CSS?

The short answer is RGB.

The slightly longer answer is that Hex values have become the de facto standard for use in CSS code and both developers and designers are used to them.

The long answer is that, in the final design on the screen, there is no difference between using Hex or RGB values in your code. Which system you use is really a matter of you own personal preference (and those of the team you are working with) as to whether or not you use Hex or RGB values to define colors.

Expand Your Font Repertoire

By Jason Cranford TeagueNov 30, 2009

Q: Are there alternatives to Arial, Times, and Georgia for Web designers?

The short answer is YES!

The slightly longer answer is that most designers use Arial, Times, or Georgia, and, to a lesser degree, Verdana, Trebuchet MS, Courier, and Comic Sans because they think that’s all they have at their disposal, but they are wrong.

The long answer is that the core Web fonts (the one listed above plus Impact and Web Dings) are used because they are almost guaranteed to be installed on the vast majority of computers your designs are likely to be installed on. One fact of life in Web design is that unless the end user's computer has access to the font file, then the browser cannot use it.

Everyone is a Web Designer

By Jason Cranford TeagueAug 10, 2009

Q: What is a Web Designer anymore? It was easier to make Web sites all by yourself, even 5 years ago, but now there is just too much technology for one person to handle. If I want to make a Web site for a very small business, don't have I to be web "developer" now?

The short answer is that everybody is a Web designer now.

The slightly longer answer is that Web designers are practitioners of a highly specialized discipline that requires years of study to truly master.

The long answer is that a good Web designer is a good designer, and this can come “naturally” or from training, but is not medium-dependent. However, a professional Web designer has to understand the medium well enough to know its strengths and limitations. Any designer can pump out something that looks brilliant when displayed in a Web browser window, but is slow to load, static when loaded, and completely unusable.
