  • Learn to Code: Wisdom and Tools for the Journey (Publication)
    It's no surprise that more and more people, from all kinds of backgrounds, are deciding to learn to code. But, each person who tackles the task is soon faced with an unpleasant reality: Learning to program is hard. Contrary to expectations, the feeling of "I don't get it," may persist unabated long into the journey, making once bright-eyed beginners feel hopeless, lost, and ready to give up. The moral of the story is this: Be prepared. The path to programmer paradise is a long one, and without the right mindset at the beginning, it can quickly lose its appeal. In this article, I'll attempt to give you some guidance on what to expect on your journey, how best to go about it, and what tools and resources you may find helpful along the way.
  • A Digital Nomad Adventure: Traveling with Hacker Paradise (Publication)
    The nomadic lifestyle is not a vacation. There remains an impermeable barrier between the work world within the computer, and the real world outside of it. Yet there is so much intellectual stimulation and inspiration to be found on the road, it's a genuine shame that we can’t build on it in the work we do, and with those we find around us. Making that dream a reality is the goal of Casey Rosengren and Alexey Komissarouk, founders of Hacker Paradise.
