i can number of times number multiply until reach limit: var velocity = -5.706875; var friction = 0.9925; var limit = 0 var times = 0; while (math.floor(math.abs(velocity)*10) > limit) { velocity *= friction; times += 1; } // times = 538 is there way times without loop? tried math.log(5.706875, 0.9925) gives result. sure, there are: times = math.ceil(math.log(-0.1/velocity)/math.log(friction)); edit: actually, taking account limit var, be: times = math.ceil(math.log(-(0.1+limit/10)/velocity)/math.log(friction));

suppose have rdd (50m records/dayredu) want summarize in several different ways. rdd records 4-tuples: (keep, foo, bar, baz) . keep - boolean foo , bar , baz - 0/1 int i want count how many of each of foo &c kept , dropped, i.e., have following foo (and same bar , baz ): rdd.filter(lambda keep, foo, bar, baz: foo == 1) .map(lambda keep, foo, bar, baz: keep, 1) .reducebykey(operator.add) which return (after collect ) list [(true,40000000),(false,10000000)] . the question is: there easy way avoid scanning rdd 3 times (once each of foo , bar , baz )? what mean not way rewrite above code handle 3 fields, telling spark process 3 pipelines in single pass. it's possible execute 3 pipelines in parallel submitting job different threads, pass through rdd 3 times , require 3x more resources on cluster. it's possible job done in 1 pass rewriting job handle counts @ once - answer regarding aggregate option. splitting data in pairs (keep, foo

how write function copy 0-15 bits 16-31? unsigned int n = 10; // 1010 copyfromto(n); assert(n == 655370); n = 5; copyfromto(n); assert(n == 327685); n = 134; copyfromto(n); assert(n == 8781958); you want copy bits in 0-15 16-31. should understand multiplying 2 equivalent shifting bits of number once left (moving higher bits). if number n , n << 16 shifting number 16 bits left. equivalent multiplying n 16th power of 2, happens 65536. to copy bits, , keep original bits in 0-15, command n = n + (n << 16); should work. however, issue (as pointed out in comments), upper 16-31 bits still set in n + term. need clear these bits. note 65535 corresponds 2^16 - 1, , have first 0-15 bits 1, , others 0. correct command n = (n && 65535) + (n << 16);
