Are traditional web frameworks and languages like RubyOnRail, Spring Boot and PHP dying now when new fast reactive pure JavaScript frameworks and services like Meteor, Node, Angular 2.0 and Firebase are breaking ground?

No.

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.

Are Django versions released too often?

The Django release process is well documented (see Django’s release process) and has been specifically designed to address the concerns of developers who don’t want to have to spend too much time keeping up to date with the latest version.

For a Django application, deployed on Heroku, what are my options for storing user-uploaded media files?

S3 is really a no-brainer for this, it’s extremely inexpensive, very easy to integrate with and unbelievably reliable. It’s so cheap that it will be practically free for testing purposes (expect to spend pennies a month on it).

What advice would Simon Willison give to a beginner Python/Django developer?

Build something and put it on the internet. Make sure you have an easy way to deploy new versions (Heroku is a good bet if you don’t want to figure out Fabric). Pick a project that’s useful to you—a simple blogging engine is often a good bet, or maybe something that aggregates together your posts from Twitter and Instagram and so on. Or come up with something a bit more creative!

How can I detect manual record insert from mysql cansole into my code in django .?

You can’t. The best you can do is have Django periodically poll MySQL to see if anything has changed (maybe with a custom management command run by cron)—having a TIMESTAMP field on every table which will be automatically set to the current time when a record is inserted will help you spot things that have changed.

Django (web framework): What are the Best Practice For Displaying another Website from yours?

This isn’t really a Django-specific question—the answer would be the same no matter what server-side tech you use.

What are some apps, problems you would suggest to solve a new python developer?

The best way to learn python in my opinion is using the interactive prompt. Install ipython (a massive improvement on the standard python shell) and use it to interactively solve some simple tasks—things like downloading a CSV file from the web using the urllib library, parsing it with the csv module, then poking around in the data using python list comprehensions and saving some of the results out to a JSON file.

Why does Django still not have support for multiple joins?

I don’t fully understand the question, but if you’re talking about doing a single join across multiple tables the Django ORM handles that just fine. Let’s say you want to get every BlogEntry written by a User who belongs to the Group with the name “admins”:

What are the tradeoffs (e.g. development speed, performance, scalability) between using various php frameworks, ruby/rails, or python/django?  Is there any reason to choose one overwhelmingly over another?

At this point, I’d argue that the decision between them comes down to programming language rather than framework—the frameworks have mostly converged on a very similar set of features.
