Github is my resume. I remember the first time I heard that statement - a couple years back Eric Florenzano said it to me on Twitter when I posted my resume publicly and asked for opinions. At the time I laughed at his statement, because it felt like naive arrogance to ditch the idea of a resume and 'traditional' social networking like Facebook and LinkedIn. How wrong I was... Before I go any further, this isn't to say that education, job history, and references aren't important in getting jobs that utilize a lot of Python. They are important, but I think they go more towards shaping you as a person than getting a job. So if you want access to Python jobs (and possibly other open source languages), you need to be able to show working code. Why is this the case? I can thing of several reasons: Python employers want to review your code in a public repo. That puts the pressure on you doesn't it? Python employers are smart enough to read your commit log.
So as a beginner, what can you do? Github, not LinkedIn. Git cheat sheets. Build software better, together. GitHub Pages.
