In light of the Heartbleed bug, Darcy Casselman would like to nominate OpenSSL for the FLOSS Fund. He writes:
So according to this article, the OpenSSL Foundation gets about $2000/year
in outright donations, mostly in small amounts.
I think this week we've come to realize how important their work is to the
Internet in general. We could probably toss them a few coins.
