    v7 v8  
    3232  * simtest IPP->PSPS test configuration debugging continued.

     34  * Wrote new perl function to implement safe stdio redirection. Modified many of the ippScripts to use it.
     35  * 1 day as official processing czar and many hours "assisting". Since the number of nodes with free disk space is currently small the IPP has more errors to repair.
     36  * Postage stamp server monitoring and repair: We had quite a bit of activity last week. The error rate was much higher than expected so I investigated. The problem was primarily caused by ipp005 outage from several weeks ago. Components were marked as gone when they should not have been. Repaired these.
     37  * At the end of the week it was decided that the update processing was placing too large a load on the database and processing nodes. Tuned some parameters for both of those.
     38  * Made postage stamps from some special processing that Gene did for Niall.
     39  * Started looking at the 450% worse false streak reporting that is affecting M31 observations this year. The M31 team considers the data '''unusable''' as is. It does not seem to be due to the new template or tessellation. This Summer's counts were worse than 2010 before we switched.
