For one and a half year, I built and used a personal knowledge base that works in my terminal and a web browser. I have found some interesting things: * if we go overboard, organizing, not learning, often becomes the goal in itself. * searching is far more effective than organizing. My knowledge base became a buffer for my web search. * a knowledge base needs to be local first and open source because learning is for life, and services and software come and go. * we will never one day sit down and read our knowledge base. * a personal knowledge base enables us to simply share a piece of knowledge with others. Doing so saves time when complex ideas need to be conveyed. * adding ideas to a knowledge base is like committing to a source control, reducing my cognitive overhead. Ultimately, having a personal repository of knowledge has helped me learn and save time.
