I’m sort of obsessed about iteration speed. I’ve written about this in the past and it deserves more posts in the future, but the quick summary is that iteration speed is always going to be the strongest competitive advantage in this industry. There’s of course many ways we can iterate faster, but for today let’s focus on two particular aspects of it: testing and deploying more often.
Do you think of yourself as a Python programmer, or a Ruby programmer? Are you a front-end programmer, a back-end programmer? Emacs, vim, Sublime, or Visual Studio? Linux or macOS? If you think of yourself as a Python programmer, if you identify yourself as an Emacs user, if you know you’re better than those vim-loving Ruby programmers: you’re doing yourself a disservice. You’re a worse programmer for it, and you’re harming your career. Why? Because you are not your tools, and your tools shouldn’t define your skillset.
