Welcome to Hard Answers
Hello and welcome. I’m Ned Martin. Ever spent a long time finding the answer to something? I have, and when I do, I put it here in the hope that it might help someone else—plus, if I ever need it again… I know where to look.
Got a question? Ask me.
Or, if you’ve found an answer to something you think would help other people, let me know, and I’ll add it to my growing collection of hard answers.
