Note: Our initial performance observations were focused on touch response and not system-wide performance, and were based on a Galaxy Nexus being used by one of Google’s staff. The demo units during the show were definitely smoother in operation. All of them featured an early build of Ice Cream Sandwich, however, so we’ll make our final calls on the phone once we have a review unit in hand.
Is that a "misstep," then? It seems to me that the logic of a too-tight misstep would be that the information simply does not get out. What would be the reason for FB (or whoever) to notice that too little of my information is getting out? I suppose the "misstep" is in the eye of the beholder. :)
note that this is just part 1 of 4.
(I am assuming you didn't read all four parts, because that material would have to be covered impressively quickly to fit in 20 minutes)
Well, 20 minutes was perhaps an exaggeration, but in our first lecture we covered everything up to the end of part 2 and most of part 3. I think in the second lecture we did a significant amount of part 4, but then we went in a different direction.
We certainly did changes of basis and arbitrary dimensional rotation in our first lecture. We didn't do quaternions, and in fact never did in the context of these sorts of things.
Of course, we had done basic vectors and matrices in secondary school - we certainly knew how to multiply N dimensional matrices, and were expected to invert 2-D matrices by hand and compute the determinant of 3-D matrices. They were on the final exam.
portal: the flash version seems to work well enough.
The directions are constant, but the momentum gives you time to shift your heading as you enter/exit portals
Like all good lessons, this one starts with a little lie and tells you the truth later on...
"Supriya : But how I will create different types of Chutneys?
Shekhar : Now you will see the missing phase of MapReduce — Shuffle phase. MapReduce will group all the outputs written by every Map based on the key. This will be automatically done for you. You can assume key as just a name of ingredient like Onion. So all the onion keys will be grouped together and will be transferred to a grinder which will just process onions. So, you will get onion Chutney. Similarly all the tomatoes will be transferred to the grinder marked for tomato and will produce tomato Chutney."
