Comment on Good ALT Attributes by bop nam

Attributes exist in two forms: attributes that are defined in the Common Language Runtime's base class library and custom attributes that you can create, to add extra information to your code. This information can later be retrieved programmatically.

[...]It’s sobering to see how many errors there are in a site that you thought you’d coded with great care to meet all the rules - but that’s what makes this tool so valuable[...]

Lorelle writes about the W3C Multipage Validator. Validating markup of the entire site with the traditional validator was time consuming and usually led to skipping some pages. The multipage validator makes it very convenient. It internally uses the same validator, but indexes multiple pages of your website and reports using AJAX. You can give your feedback and contribute to the tool. A great find, thanks Lorelle!

Comment on How can I hide my HTML Source? by Dominic

However, I think that copyright makes sense. What makes no sense is to try to use technology to prevent people to copy your work that is available on the Internet. They try to do that with videos, but it does not really work. It sends the wrong message. People think that if they can defeat the technology, then it’s fine. It isn’t.

I think the best way is to rely on the standard copyright approach that we use for books, etc. In the same way as authors and publishers, even though there is no technological constraint, do not use copyrighted work, web designers and web masters should not use copyrighted material in their web site. Why this approach, which works fine with books, does not work with website material? I think that the only reason is that a different category of people, less respectful of the work of others, design and maintain websites.

This is not easy work, but the rewards are significant: a stronger civil society where all mem- bers feel included, respected, and responsible for building community. ,
