Even if we the spread of the virus is contained in the next 30 days (personally I am very pessimistic), the devastation left by it is going to last a while - already hundreds of thousands of people have lost their jobs and this is going to worsen.

How can someone with no money, but some tech skills/time/willingness, help in this situation?

Edit : Also, how can ordinary Joe/Jane be prepared for something like this in future without looking up to the government and the generosity of a handful of billionaires like Bill Gates (nothing against him, he is doing great work)? I understand the normal stuff - keep some savings, keep some canned food, be in as good health as possible etc. But these aren't enough?
