There are a few partial solutions on the web but none of them properly deal with sites using HTTPS, so here's my solution:
This is a slightly edited response I recently wrote to someone who asked how to learn skills that would be useful at a hackathon. It's my usual response when someone asks how to get started programming.
You should start by approaching the problem from a different perspective. You should be thinking "I want to build X. Now what do I need to learn to build that?" not "I want to learn to build stuff. What can I learn?"

I've also discovered that learning to code can have a big impact on your personality. Coding uses a lot of thinking patterns that I hadn't really used since my math and statistics classes in college, and even back then not in this intensity. As a result I've become more focused, more logical and smarter. But I've also become more detached from everyday life and less fun to hang out with.
