Power Restored

It's been a long time since I last put in an entry because I just got power restored. An ice storm hit Wednesday night last week and I was out of power until now. The short of things is that I haven't worked on the NCNI project since my last entry, but I Ketan and I have done a lot of rethinking and remodeling of the TiVo Nation simulator.

Our first and second attempts ran into problems because we didn't accurately consider several things, and used parameters that really don't matter at all (although they seemed somewhat important before). Right now, I'm changing the model so that we don't care about compression but instead are only interested in at what point of error does a fully aware system perform better than a semi-aware human. We also did not include a utility decay factor in my previous simulations, although I remember we had talked about that a long time ago; that's why I have always had a timestamp attached to objects. Without this decay making old shows less useful, since a user can never watch as many shows as could be recorded, the cache simply becomes saturated at some point.

So, I'm going to do some runs this weekend and meet with Ketan on Monday to discuss things. I'm think we'll get some good results this time. The submission date has been pushed back to December 31, so we have some time left to do this right.
