COVID-19: How can developers help combat it?

How can we use our unique skillset to help our communities?

As developers we can easily work from home; in fact many of us already do this everyday. The current lockdowns being enforced around the world mean we'll now spend even more time at home - and no doubt on our computers!

We also have a unique skillset that means we have the ability to help our communities even though we are isolated.

This could be as simple as offering IT support to those in our local communities / families who are not very tech-savvy.

Today for example, I am helping a neighbour set up Zoom so she can remain connected. I plan to create a simple website that contains simple setup info for this and other apps for similar people to use.

But I think we can use our skills to do more.

This site was recently created to help nurses and the most vulnerable during the COVID-19 crisis stay at home and not risk their lives:

This site by @trekhleb shows the dynamics (the curvature of the graph) of oronavirus distribution per country.

Do you know of any other sites like this?

What else could we build as a community that could help others?
Perhaps something that makes it easier to organise collection of food / medical supplies?

Do we even need something - are WhatsApp etc enough?
