Growing your inner data scientist

So you've recently found a passion for data science. What next? In this talk I'll try to convince you of the value and effectiveness of sharing your work, contributing to open source projects, collaborating with others, and broadcasting your accomplishments (from small to big). In addition to why, I will also discuss how you can most effectively and efficiently do these, including giving pointers for tools you can use to streamline your process for building a public portfolio.
