sql - Is there a faster alternative to "group by" aggregation in Netezza? -

-
this minimal query statement want execute. select count(*) temper_300_1 group onegid; i have "where" clauses go along though. trying build histogram query , determine number of elements particular "onegid". query takes 7 seconds on 800 million rows. suggest faster alternative or optimization. i trying plot heatmap spatial data consisting of latitudes , longitudes, have assigned grid id each elements, "group aggregation" coming out pretty costly in terms of time. you're not going faster group by , though current query won't display group item associated each count. make sure table distributed with select datasliceid, count(1) temper_300_1 group onegid; the counts should equal. if they're not, dba needs redistribute table on better distribution key. if is, ask dba create materialized view on specific column, ordered column. may see performance gains.

java - Create all combinations of mappings of characters to truth values -

-
i have set of characters {'p', 'q', 'r', ...} , want call run() (not important does) on permutations of mappings characters boolean values. example, if set of characters {'p','q','r'} , naively went through every permutation manually, this: private static void runmaps(){ hashmap<character,boolean> m = new hashmap<>(); m.put('p', true); m.put('q', true); m.put('r', true); run(m); m = new hashmap<>(); m.put('p', true); m.put('q', true); m.put('r', false); run(m); // ... // 8 permutations } it's bugging me because know can (and should able to) use recursion here i'm struggling. edit : after while managed working. there's added stuff in code below general idea shown. private static boolean runmaps(syntaxtree formula, arraylist<string> chars, hashmap<string, boolean> map, int index) { if (i...

r - Add rows by groups -

i observe frequencies (eff) of different characters (code) in population @ different dates (date2). datas <- data.frame(date2 = rep(seq(sys.date() - 2, sys.date(), = "day"), each = 2), date1 = sys.date(), code = rep(letters[1:2], 3), eff = c(50, 30, 20, 10, 20, 20), total = 100) > datas date2 date1 code eff total 1 2015-07-25 2015-07-27 50 100 2 2015-07-25 2015-07-27 b 30 100 3 2015-07-26 2015-07-27 20 100 4 2015-07-26 2015-07-27 b 10 100 5 2015-07-27 2015-07-27 20 100 6 2015-07-27 2015-07-27 b 20 100 for each dates2 add code "fill" difference between sum of frequencies day , total population observed day (total). for example, output i'm expecting : date2 eff date1 total code 1 2015-07-25 50 2015-07-27 100 2 2015-07-25 30 2015-07-27 100 b 3 2015-07-25 20 2015-07-27 100 ko 4 2015-07-26 ...

r - Fill target array with dynamically shifted source array -

-
what way shift array number given per column? i have following method filling full size array ("o") values of different array ("p", dimnames(p) exist in "o"). # empty target array o <- array(dim=c(6,3),dimnames=list(c(1:6),c(1:3))) # partially filled source array p <- array(c(10:16),dim=c(2,3),dimnames=list(c(2:3),c(1:3))) > p 1 2 3 2 10 12 14 3 11 13 15 # fill target array p o[(match(names(p[,1]),names(o[,1]))),(match(names(p[1,]),names(o[1,])))] <- p > o 1 2 3 1 na na na 2 10 12 14 3 11 13 15 4 na na na 5 na na na 6 na na na now rewrite matching array call shift each column value in column header (only simplification picked 1:3). in example, shift first column 1, 2nd column 2 , on). the result this: 1 2 3 1 na na na 2 na na na 3 10 na na 4 11 12 na 5 na 13 14 6 na na 15 is there way solve without going manual looping? i have tried in direction o[(match(names(p[,1]),as.integer(name...

xcode6 - Particle Emitter not acting consistently -

-
i'm using same particle emitter in multiple scenes, , i'm noticing in scenes when run app on phone emitter isn't appearing when supposed to. changes different scene next time open app it's inconsistent. thought creating different emitter each scene seems pointless if 1 emitter can used across scenes. saw question related: spritekit particle emitter not appearing in xcode editor but no answers, wondering if else has same problem? problem sourced z position of emitter node, set equal background can assume caused act strangely when set z position higher stopped.

javascript - A Store of Actions for optimistic updates is a good approach in Redux/Flux? -

-
i've been working optimistic updates in react+flux application , saw 2 things: what happens if user attempts close window when exists uncompleted actions. example in facebook, message appears in wall if wasn't persisted (this optimistic updates does, more responsive application user). but, if user post in wall , close application (on logout or window close), post fail , not alerted. i don't idea of stores managing own entities (for example messages) , situation of action triggered persiste message (loading, succesfull, failed?). mixes things. so work on , create actionstore manage state of actions triggered components. here is source code , here is live demo. it works more or less this: the root of components hierarchy (container in redux) fetch nextid of new action , pass childs props (this ugly). a child component fires action: keeps actionid ask store after , call action creator. the action creator creates new action , returns function middleware. ...

i've been going through exercises book on algorithms (with emphasis on python), , strange behavior when try solve problem. exercise straightforward , goal generate random integer k range(n) , , locate number through sequence of "yes / no" questions. following code works long n isn't large, when infinite loop. shouldn't happen because in worst case step_size equal 1 , position crawl towards value of k until position == k . when print both step_size , position seems position isn't updating when gets large, i'm guessing has value getting approximated , truncated (this why tried explicitly cast long, may not in fact doing anything). minor parts of code unnecessary, wanted have work general n . ideas what's going on (you have increase n behavior i'm talking about)? from random import randrange math import ceil n = 10**15 k = randrange(n) success = false step_size = ceil(n / 2.0) position = long(ceil(n / 2.0)) print(k) while suc...
