This is a design that comes up in roundups every once in awhile, and small wonder, it’s neat. Newspond is a sort of news aggregator with a science and technology focus. They determine article importance with their own automated metrics rather than solely by user votes. It’s kind of like TechMeme before they decided to start having editors, but much better looking.

You may already be familliar with the problem of MySQL Injection, a common exploit that can cause irreparible damage to a database.

The ?’s are place holders until the next line where we bind our parameters to be the username and password. The rest of the code is pretty much just calling methods which you can read about by following some of the links at the end of the article.
