What is HTML validation?

You may not bother with html validation or writing simple and clean code when designing your web site. Later you may find your site is slow loading, appears incorrectly in the main browsers and does not rank well for the major search engines.
Now there are sites that still do rank well even though the html code has many errors. This is because most of the current major browsers are still very forgiving of html mistakes, however future browsers will become more html compliant as the Internet advances. Sites that have not bothered with html code validation will then fall by the wayside or take time and money to be corrected.
That's why you should take the necessary steps NOW to make sure that the code on your web site is validated.

NXL and its properties

What is NXL? NXL is a leading group of talented transportation engineers, surveyors, and construction managers who provide their clients with services of the highest caliber.

It is that pledge for excellence that has transformed NXL into a company with over 100 talented employees providing services on world-class projects throughout the United States and abroad.

What is RSS and benefits!

What the heck is the RSS thing? Is it just hype, or is there really something to it? Why should I care? I have had these same questions myself along the way to my current total dependence on RSS. Please allow me to add to the hype you've already heard: RSS has changed the way I use the web. It's funny, developer.* has offered RSS feeds for a long time—and as a reader I experimented with some early RSS aggregators a few years ago—but it was awhile before I really jumped on the bandwagon for my personal web reading. Now I subscribe to a few dozen feeds, and I add more to my subscription list all the time.

What I like best about RSS is that it gives me a lot of control over my web reading experience. I can target my reading much more specifically, and I don't miss new things from sites and bloggers that I might forget to check. (A lot of the RSS feeds I read are for blogs, but all kinds of web sites have RSS and Atom feeds now. For example, a couple friends of mine have an RSS feed for their online web comic. You can even watch CraigsList categories with RSS.) When the web sites one wants to keep up with number in the dozens it becomes too much to remember to go check those sites, many of which will be updated on an irregular or infrequent basis. If a site or blogger I like has a feed, I'll add it to my list.
