Myself and Raghavendra (@rabhat) have been discussing about BitRot[1] and came up with a list of high level tasks (breakup items) captured here[2]. The pad will be updated on an ongoing basis reflecting the current status/items that are being worked on. As always, contributions in any form (design, code, doc, etc..) are more than welcome (just make sure you're heard on the pad/email :))<br>
