Validation Suggestions

I was reading some articles about validation routines in Flex (as part of a book I’m writing on Flex + PHP), when I came across a particular article that’s part of  the Adobe Developer Connection. The specifics of the article revolve around validation in Flex, of course, but I thought that the section on “Best Practices for Client-Side Validation” would be good reading for any one doing user interface. There are four suggestions there, all on how an application should treat the user. Those suggestions are:

  2. Give Immediate Feedback
  3. Let the User Work
  4. Innocent Until Proven Guilty

The first rule ties in nicely to a post I just wrote on putting the user in a place where they can succeed.

But, yes, SiteGround offers hosting accounts with several different versions of PHP. I know nothing of the company or the quality of their hosting, but if you want to try PHP 6, without installing it on your own computer, this is a cheap option.

The Economics of Publishing

However, I only have access to my numbers as a writer, so it was interesting to see the publisher side of things. I write computer books published as paperbacks, so my experience may differ from what the Times reported. That being said… (continue reading…)
