Help Craig Newmark find a new hobby on Twitter!

Internet celebrities are not celebrities in a sense that you can easily communicate with them on services like Twitter (assuming the services are not down). There’s no such thing as an internet bodyguard except some firewalls in Windows. So this day I found Craig Newmark, Craigslist founder tweeting this:

I suggested him a forward looking hobby:

To my surprise I got an the following answer back:

Well first step in case of every hobby is to ‘like the idea’…even if the brain hurts at the beginning. Tinkering in the backyard is a lot healthier than sitting in front the screen.

  1. 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.
