The Singularity Institute for Artificial Intelligence, the nonprofit I work at, is currently running a Summer Challenge to tide us over until the Singularity Summit in October (Oct 15-16 in New York, ticket prices go up by $100 after September starts). The Summer Challenge grant will double up to $125,000 in donations, ends at the end of August, and is currently up to only $39,000 which is somewhat worrying. I hadn't meant to do anything like this, but:

I will release completed chapters at a pace of one every 6 days, or one every 5 days after the SIAI's Summer Challenge reaches $50,000, or one every 4 days after the Summer Challenge reaches $75,000, or one every 3 days if the Summer Challenge is completed. Remember, the Summer Challenge has until the end of August, after that the pace will be set. (Just some slight encouragement for donors reading this fic to get around to donating sooner rather than later.) A link to the Challenge and the Summit can be found in the profile page, or Google "summer singularity challenge" and "Singularity Summit" respectively.
