i have code: actioncable.server.broadcast "posts_#{self.post_id}", { object: some_object } i'd send same payload multiple broadcastings. obvious way pass array of broadcastings: actioncable.server.broadcast ["posts_#{self.post_id}", "all_posts"], \ { object: some_object } but seems treat entire array being identifier: [actioncable] broadcasting ["posts_30453", "all_posts"]: ... and neither broadcasting recieves message. it seems there should cleaner way calling actioncable.server.broadcast multiple times. there? i build tiny helper gem ( multicable ) this. adds broadcast_multiple method actioncable::server: > actioncable.server.broadcast_multiple ["broadcasting1", "broadcasting2"], { payload: "whatever" } [actioncable] broadcasting broadcasting1: {:payload=>"whatever"} [actioncable] broadcasting broadcasting2: {:payload=>"whatever"} eith

this question has answer here: sort array containing objects based on array [duplicate] 2 answers here's mean. suppose have array of objects var objs = [ { foo: 5, bar: "something"}, { foo: 4912, bar: "blah" }, { foo: -12, bar: "hehe" } ]; and array defines ordering on bar values, var arr = ["blah", "something", "hehe"] does javascript have way of getting version of objs to [ { foo: 4912, bar: "blah" }, { foo: 5, bar: "something"} { foo: -12, bar: "hehe" } ]; ??? the best way know like objs.sort(function(x,y){ var ix = arr.indexof(x), iy = arr.indexof(y); if(ix<iy) return -1; else if(ix==iy) return 0; else return 1; }); but i'm wondering if there's way more compact. you can refa

i have std::vector filled following structures: #define elementsize 8 struct element { int value; char size[elementsize - 4]; //1 char 1b in size - 4b int }; the size of structure depends on defined elementsize, makes array of chars of specified size in structure. i benchmarking average value of these structures in vector , love know reason why vector filled bigger structures in size takes longer iterate over. for example vector 1 000 000 8b structures takes 1,7ms , same test 128b structures 12,7ms. is big difference because of cache only? if so, explain why? or there other aspect can not see? the structure 16 times bigger, should take 16 times longer iterate through. mathematically 12,7/1,7 = 7,47 times more, matches mathematically. now imagine structure containing 128b elements structure containing 8b elements, same size. see 16 times larger?

i've been told reversing bits of integer in divide-and-conquer fashion (i.e. first swapping every 2 consecutive bits, swapping 2-bit pairs, , on until result) o(logn), fail see how o(logn).. consider case when swapping byte (8 bit): first swap every 2 bits , perform 4 swaps, swap 2-bit pairs have 2 swaps , join in last swap. total: 7 swaps, log(n) have been 3. am right or missing something? you're counting else. if add "individual swaps", that's lot of swaps. whole point of technique (and many similar techniques) "phase", swaps in phase happen in constant number of steps. example step "swap adjacent bits": x = ((x & 0x55) << 1) | ((x & 0xaa) >> 1); .. or equivalent delta-swap formulation, looks no matter how many swaps it's doing (the constants change of course). so, that's constant number of steps right there.
