The United States is celebrating Thanksgiving today. Thanksgiving is my favorite holiday, because it allows everyone, regardless of their religion or personal philosophy, to join together as a nation in thanks for the many wonderful things this world provides.
This year is a particularly great Thanksgiving, because we have a newly elected President. Billions of people throughout the world hope that our new leadership will contribute to multinational efforts to reduce global warming, to use resources wisely and fairly, and to reduce violence and disease.
As someone who specializes in the field of biomedical informatics, I am personally grateful for the infrastructure that permits me to contribute to society, just by sitting at my computer and using the publicly available digital resources.
Here is the list of free resources that I am particularly grateful for (many of which accept charitable contributions):
Languages and software
Nomenclatures and ontologies
Standards and protocols
There are many many others, but these are all that I can think of at the moment. Please feel free to add your favorite free data resources, for which you are particularly thankful.
