Should I use Django forms or pure HTML in order to do not establish borders for the growth of my app?

Use Django forms. Django scales horizontally on the front-end, so if your site needs to handle large amounts of traffic you just need to run multiple front-end servers—your form handling code will scale up just fine.

Which web/software development conferences a student should attend and why?

Offer to volunteer at conferences. If accepted, you’ll get in for free and you’ll get to meet loads of people (including spending time with the speakers)—in exchange for a full days work manning desks, finding speakers in time for their talks, giving people directions and generally helping organise and clean things up.

Has JSON pretty much replaced XML for string processing for the web, or are there use cases where XML is still necessary?

It’s replaced XML as the default format for most APIs. XML is still necessary for Atom/RSS feeds and other existing standards built on top of XML.

How do you change page content and URL without reloading the whole page?

This can only be done using JavaScript. You use XMLHttpRequest to pull in new information from the server (also known as Ajax—most people use a JavaScript library such as jQuery to handle this) and then use the HTML5 history API, in particular the pushState method, to update the URL.

How long until Ruby developers are as cheap as PHP developers? is it already happening? should I still learn it or it only has a couple years left and I’m better off with SSJS?

If you want to be a highly paid engineer, you should worry less about your expertise in a specific language and more about developing broad and deep skills across a wider range of development topics.

Why do websites contain multiple webpages when they could use AJAX?

Because it shouldn’t require a full-blown JavaScript interpreter just to access content on the Web.
