Well most replies already suggested a LLM but good old fashioned search skills work fine too.

For simple questions, as long as you know the correct terminology that is relevant, just asking the question of a search engine is usually good enough to turn up articles or stack overflow answers that'll help

If you don't know the terminology or you struggle to ask a precise question despite your knowledge, going up one level , so to speak, and consuming more information about the stuff in the immediate context, can often either fill in the gaps to allow you to ask the right question, or sometimes it's the missing bit of info you didn't know you needed to solve your actual problem.
