For those of you who need to regularly switch between programming languages, libraries, tooling and anything else used in software development for work, I'm curious to hear about any practical measures you take to stay afloat and be productive. I've given mind-mapping and flash cards a whirl, but I've found personally that neither have been sustainable in the long-run.<p>One of my motivating reasons for asking this question is because (as a generalist) I feel like imposter syndrome is starting to get the better of me.
Focus on the task not the tools (unless you are building a tool/language/library). Whatever you are trying to build is always going to involve a very small fraction, of all the capabilities every language/library/tool provides. So focus on the capabilities you need. Don't fill your head with stuff that you don't use.
