2012-10-11T08:56:34  <ecthiender> arvind_khadri, so what do I look into it?
2012-10-11T08:56:40  <ecthiender> arvind_khadri, I mean what do I do?
2012-10-11T08:57:44  <arvind_khadri> He was saying that probably look into that images thing, where you can create a street view kind of thing using them.  And also about that spinning issue.

2012-10-11T11:50:58  <arvind_khadri> ecthiender, yes :D
2012-10-11T11:51:01  <arvind_khadri> hilarious
2012-10-11T11:51:15  <ecthiender> arvind_khadri, what is hillarious? :o
2012-10-11T11:51:42  <arvind_khadri> ecthiender, the one that I gave you, and the one that you sent was nice.  Great explanation
2012-10-11T11:52:13  <ecthiender> arvind_khadri, I didnt know anything about compiler optimizations. so I didnt know about branch predictors and stuff. found pretty interesting
2012-10-11T11:52:31  <arvind_khadri> ecthiender, yea.
2012-10-11T11:52:44  <arvind_khadri> It was interesting.
2012-10-11T11:52:56  <ecthiender> arvind_khadri, btw what will the bitwise operation do : int t = (data[c] - 128) >> 31;
2012-10-11T11:52:57  <ecthiender> sum += ~t & data[c];
2012-10-11T11:54:25  <arvind_khadri> ecthiender, it will right shift 31 by so many 0's
2012-10-11T11:55:16  <ecthiender> arvind_khadri, umm I'm pretty bad with bitwise. I dont the language you are speaking :P. I want to know how it is equivalent to :
2012-10-11T11:55:32  <ecthiender> if(data[c] >= 128) { sum += data[c]; }
2012-10-11T11:55:39  <ecthiender> arvind_khadri, ^
2012-10-11T11:58:38  <arvind_khadri> ecthiender, hmm, so let us say that data[c] = 138, then the if evaluates to true and sum becomes 138, assuming sum = 0.
2012-10-11T11:59:32  <ecthiender> arvind_khadri, what? did you follow the question?
2012-10-11T11:59:54  <ecthiender> arvind_khadri, I asked how are the bitwise statements achieving the same thing as above.
2012-10-11T12:00:21  <arvind_khadri> yes that is what am explaining.  Let me finish man :)
2012-10-11T12:00:34  <ecthiender> ok
2012-10-11T12:00:59  <ecthiender>  so you should indicate that with .... probably :P
2012-10-11T12:02:57  *** pradi <pradi!~Adium@122.167.217.160> has joined #amclug
2012-10-11T12:03:19  <arvind_khadri> so then ``int t =  (data[c] - 128) >> 31;`` will evaluate to 10 >> 31
2012-10-11T12:04:26  <arvind_khadri> which is 0
2012-10-11T12:06:01  <arvind_khadri> and sum evaluates to 0, as sum = 0 + 1 & 138
2012-10-11T12:06:42  <arvind_khadri> ecthiender, ^
2012-10-11T12:08:06  <ecthiender> 10 >> 31 is 0?
2012-10-11T12:08:08  <ecthiender> arvind_khadri, ^
2012-10-11T12:09:28  <arvind_khadri> ecthiender, yes :)
2012-10-11T12:09:36  <ecthiender> and then what is ~t?
2012-10-11T12:09:46  <arvind_khadri> complement of t
2012-10-11T12:11:44  <ecthiender> so complement of t will be 1
2012-10-11T12:11:48  <ecthiender> arvind_khadri, ^
2012-10-11T12:12:11  <ecthiender> what will be 1 & 138? arvind_khadri ?
2012-10-11T12:12:15  <ecthiender> 1 right?
2012-10-11T12:12:15  <arvind_khadri> yes that is why the equation becomes what I mentioned above
2012-10-11T12:12:25  <arvind_khadri> ecthiender, no, that will be 0 too
2012-10-11T12:12:34  <ecthiender> 1 & 138 is 0?
2012-10-11T12:12:44  <ecthiender> so sum becomes 0?
2012-10-11T12:12:50  <arvind_khadri> yes
2012-10-11T12:12:58  <ecthiender> arvind_khadri, but sum should be 138.
2012-10-11T12:13:13  <arvind_khadri> ecthiender, oh wait

2012-10-11T12:16:55  <arvind_khadri> ecthiender, you need to convert the decimals into binary or hexadecimal
2012-10-11T12:17:03  <ecthiender> arvind_khadri, binary
2012-10-11T12:17:07  <ecthiender> its bitwise.
2012-10-11T12:17:36  <arvind_khadri> bitwise works also on hexadecimal, the compiler would convert into binary anyway

2012-10-11T12:29:45  <arvind_khadri> awesome to see you
2012-10-11T12:29:48  <ecthiender> static, sorry man there is some other rohit. he is bit irritating
2012-10-11T12:30:01  <static> you guys got some other rohit
2012-10-11T12:30:11  <arvind_khadri> ya man..
2012-10-11T12:30:14  <ecthiender> static, thats why all this. yeah we were discussing branch prediction problem.
2012-10-11T12:30:18  <ecthiender> static, yeah :(
2012-10-11T12:30:28  <static> yes its simple
2012-10-11T12:30:48  <static> see the guy who posted this problem basically had a vector of numbers
2012-10-11T12:30:58  <static> he wanted to sum up all those > 128
2012-10-11T12:31:05  <static> so the if condition is there
2012-10-11T12:31:23  <static> this is replaced by the two lines you guys were discussing about
2012-10-11T12:31:34  <static> now there are two cases
2012-10-11T12:31:45  <ecthiender> static, ya we understand :) ust got stuck with bitwise operations.
2012-10-11T12:31:45  <static> one : the number is bigger than 128
2012-10-11T12:31:54  <ecthiender> ok
2012-10-11T12:31:55  <static> and second its smaller
2012-10-11T12:32:20  <static> now if its greater than we get a +ve quanitity
2012-10-11T12:32:30  <static> and 32 bits
2012-10-11T12:32:35  <static> 32/8 = 4 bytes
2012-10-11T12:32:48  <static> which  is the size of an integer
2012-10-11T12:32:57  <static> now right shift it by 31
2012-10-11T12:33:06  <static> last bist that is the left most is for the sign
2012-10-11T12:33:17  <static> so basically it gives us all zeroes
2012-10-11T12:33:39  <static> negate that and and with the original gives us the original number
2012-10-11T12:33:44  <static> so we skipped the branch
2012-10-11T12:33:54  <static> so no branch oprediction for the compiler
2012-10-11T12:34:14  <static> and is its a negative number(second cse) wher the data[c] is less than 128
2012-10-11T12:34:22  <static> the  leftmost bit is 1
2012-10-11T12:34:37  <static> so the right shift operation will make all 1's
2012-10-11T12:34:58  <static> since in right shift the extra bits a re padded according to what is there in the leftmost bit
2012-10-11T12:35:08  <static> so negate that will give all zeroes
2012-10-11T12:35:16  <static> and with anything you get zero
2012-10-11T12:35:19  <static> add it to sum
2012-10-11T12:35:26  <static> so the sum remains the same
2012-10-11T12:35:28  <static> :)
2012-10-11T12:35:41  <static> hence voilla the number is not added here
2012-10-11T12:36:18  <ecthiender> static, yeah nice. thanks :)

2012-10-11T12:57:43  <arvind_khadri> ecthiender, fucking amazing
2012-10-11T12:57:58  *** ChanServ sets mode: -o arvind_khadri
2012-10-11T12:58:33  <ecthiender> arvind_khadri, no :) imagine you and I can have a supercomputer. :) and go crazy with 64 processors :P
2012-10-11T12:58:54  <arvind_khadri> ecthiender, everyone in this world can have one :)
2012-10-11T12:59:08  <arvind_khadri> I am just dumbfounded
2012-10-11T12:59:09  <ecthiender> arvind_khadri, even the architecture is pretty amazing. and they only consume 9 watts.
2012-10-11T12:59:54  <ecthiender> we can really learn parallel programming
2012-10-11T13:01:13  <ecthiender> arvind_khadri, did you study any maths yet?
2012-10-11T13:01:25  <arvind_khadri> No man
2012-10-11T13:01:44  <arvind_khadri> I just go home and sleep
2012-10-11T13:01:57  <ecthiender> hmm. I have studied some 2 chapters of graph theory. the basic ones.
2012-10-11T13:03:48  <arvind_khadri> Nice
2012-10-11T13:20:13  <ecthiender> arvind_khadri, email the trip photos na
2012-10-11T13:20:32  <arvind_khadri> ecthiender, will do today
2012-10-11T13:20:40  <ecthiender> arvind_khadri, cool =
