 He said something like "we could spend a day just fixing the stuff our error logs turn up"  indeed that does sound plausible!  a day?  I'm sure we could make a week out of it... <^demon> Well, more I'm sure. But there's a *lot* of low-hanging fruit in the logs.  heh, indeed <^demon> Simple stuff like val/ref mismatch, missing params, fatals for stupid mistakes, etc.  a day would be a good place to start  Like ^demon said we could just hand out stuff to people  I guess I should spend that time trying to fix those stupid permissions issues on the cluster

At the NOLA Hackathon some attendees attempted to work on this. They chose a moment when very few errors were showing up in the logs, so they did not have much to work with. However, Roan fixed an issue that was cluttering up the logs with symbolic links errors. Therefore we expect that log sizes will go WAY down, helping save space and ensuring more serious errors are easier to find.
