After business consulting, I want to get back into development. Where to start?

After doing coding all through university, and then programming professionally for a few years, I decided to make a switch into business consulting.

Most of this experience was all through linux using Java, C, C++ and some 4GL work for mining companies.

I'm starting to get hungry for coding again, and am wondering what some of the better starting points would be for the type of modern web development employers are looking for these days.

This is not necessarily for moving out of consulting, but skilling up in areas that are relevant these days.

Would it be correct to say these are the areas I should be looking into?

JavaScript/HTML5/CSS3 Python, Django, and PostgreSQL

The link below seems to cover the technologies:

But are there any recommended learning resources/tutorials to get into this?

Thanks in advance.
