BioBarCamp is due in circa 3 weeks and we have now 45 BioBarCampers signed up on the list of attendees and our host the Institute For The Future has the capacity for around 55 more campers, roughly for 100 people in general. We already have a very valuable mix: researchers, biologists (grad, postdoc, PI), coders-engineers-bioinformaticians, biotech entrepreneurs, doctors, science journalists.
Here is the list so far and that’s also a chance for you to decide whether you want to join and meet us there in Palo Alto on the 6th and 7th, August and share, ask and answer, be the donor and receptor of ideas from all around biogeekdom. I am continuously trying to collect some links on the campers on the BioBarCamp FriendFeed Room to make future Campers preconnected.

Deep, healthy lifespan extension 
I’m going to be away during that time, so I regret I will be unable to attend. I’ll be expecting you to fill us all in.
It’s sound interesting.
All animals are equal, but some animals are more equal. (Proclaimed equality doesn’t mean true equality).
Soft-updates guarantees that the only filesystem inconsistencies on unclean shutdown are leaked blocks and inodes. To resolve this you can run a background fsck or you can ignore it until you start to run out of space. We also could’ve written a mark and sweep garbage collector but never did. Ultimately, the bgfsck is too expensive and people did not like the uncertainty of not having run fsck. To resolve these issues, I have added a small journal to softupdates. However, I only have to journal block allocation and free, and inode link count changes since softdep guarantees the rest. My journal records are each only 32bytes which is incredibly compact compared to any other journaling solution. We still get the great concurrency and ability to ignore writes which have been canceled by new operations. But now we have recovery time that is around 2 seconds per megabyte of journal in-use. That’s 32,768 blocks allocated, files created, links added, etc. per megabyte of journal.
