i have run various spark jobs these last months , have done performance analysis not in depth (not as have liked). have noticed drop of performance added per core when add more , more cores, expected because spark must have constant cost (or @ least not parallelizable) operations, amdhal's law applies. however, not enough explain i'm seeing. i trying reason in abstract way cost of shuffling data on network depending on number m of machines in cluster. reasoning following : hypothesis the total data size in bytes d there n >= m partitions the data randomly (in terms of partitioning function) equally (same amount d/m of data) distributed before shuffle the partitioning function balanced (=> each partition represents 1/n of data) each machine must end same number of partitions n/m on optimize distribution of data reasoning since data randomly distributed, each machine contains 1/m of each partition before shuffling. since each machine must have n/...

i novice in nodejs , have read buffer not clear. some examples:- 1) var buffer = new buffer(12); 2) var buffer = new buffer([12,54,89]); 3) var buffer = new buffer("confusing buffer", "utf-8"); here queries are, what buffer , way define/implement. what meaning of above examples. in javascript, strings not binary safe. there characters illegal in strings. this of course makes difficult process binary data such images or mp3 files since i/o in javascript deal strings. the solution node developers implemented buffers. think of buffers strings binary data (and remember, text subset of binary data). as specific questions, answer second question answers first question: the example code posted examples of how define buffers .

the following print screen shows layout: i have main view , top view , picture. when press on picture, want semi transaprent black screen appearing on entire view: let scrennrect = uiscreen.mainscreen().bounds let coverview = uiview(frame: scrennrect) coverview.backgroundcolor = uicolor.blackcolor().colorwithalphacomponent(0.3) self.view.addsubview(coverview) but want picture stay on top of coverview ? there way can bring picture in front of coverview ? the problem coverview , imageview have different super views. that's why cannot bring imageview front. in order bring imageview front need move outside of top view view contains top view , imageview. then, can add coverview main view, , bring imageview front. another solution: place image view inside coverview @ exact same position.
