When I saw this post, my first thought was that it wouldn't fit in the newsletter because it is general to tech and I've seen dozens of posts on the same topic. I chose to include it for its depth, great tips, and the sheer amount of resources presented. It's an exhaustive look at all the things you can do, at any age, if you are looking to land a good job in the tech industry. Almost all of it applies to developers.
Don't let the title fool you. You don't have to be in school to use the info in this post.
