To my surprise, tonight the ibox shows the OS as 19,968,578,256, as of 9/14/09. Thats 5 Billion more than the sum of the Float (13,833,983,958) and Restricted (1,134,594,248). Something is clearly amiss. Thinking that maybe i misread the ibox Friday, I've checked with others, but, they remember it the same as do I.
That's peculiar indeed. I'll be curious to here about your chat with the TA on Monday.
