I am software developer. An oft-repeated belief among my kind is that many problems have already been solved, and so the wise thing to do is to reuse existing solutions made by people smarter than you instead of falling into the trap of reinventing the wheel. This frees you up to deal with other problems that aren’t already solved for you.
I often spend time looking to find the accepted “solution” at any moment, and then find myself forgetting and repeating the same research to solve the same problems myself in the future. I figured I may as well document my findings over time to help my future self and potentially others as well, and from that idea a blog was born.
