Belated, and probably most of you knew already, but just in case you didn’t, the 2009 Bioinformatics Open Source Conference (BOSC) was accepted on Dec 16 as a Special Interest Group (SIG) meeting by the respective ISMB 2009 review committee. Special thanks and congratulations to Kam Dahlquist, who agreed again this year to chair the conference, and who pulled the proposal together.
