For all of those topics, I use domain specific sites. So for research I’ll look at arxiv or one of the sites that make research freely available. For programming, I’ll search language mailing lists, documentation, and examples. Searching GitHub also isn’t a bad idea, but watch out for license issues.

Be wary of using tools like got to summarize articles or outright answer questions. There’s no guarantee it will be correct, and if you don’t know the answer you won’t know it’s wrong.
