I agree with the author that you will have more opportunities if your code is online.

After graduating, I spent some time putting my personal and class projects on my website. Later in the summer I got a call from a dev manager who found my website accidentally when searching for programming info. He flew me out for an interview and offered me a job.

The job offer gave me the courage to apply where I really wanted to work: Amazon Web Services. It also sped up the Amazon hiring process.
