i creating new objects in array , want able assign dynamic name can access easier. below sample of looking do. want value 'iwantthisdynamic' able variable can name whatever choose when push array. i using javascript. ideas? in advance! myarray = []; myarray.push({iwantthisdynamic:{'color' : 'red', 'image':'3.jpg'}}); you can't arrays since array items accessed index, not key. that's objects for. myobj = {}; myobj.iwantthisdynamic = {'color' : 'red', 'image':'3.jpg'}; or if name dynamic: var dynname = 'dynamic'; myobj[dynname] = 1;

how can order sqlite query clause. for example: -------------------------------------- | id | body | -------------------------------------- | 1 |the boy going bed | -------------------------------------- | 2 |the boy child | -------------------------------------- | 3 |the boy playing computer| and search input is: "the boy going bed" so sql query be. select * data body '%the%' or '%boy%' or '%is%' or '%going%' or '%to%' or '%bed%' i want the id 1 first because have many correct clause. in sqlite, result of boolean expression 0 or 1, can add these comparison expressions: select * data body '%the%' or body '%boy%' or body '%is%' or body '%going%' or body '%to%' or body '%bed%' order (body '%the%' ) + (body '%boy%' ) + (body '%is%' ) +

im using 3 fragments in viewpager adapter . loading data parse(parse.com) , displaying them in recycler views. following code causing app crash. understanding when mainactivity loads, first fragment ie, gets viewed user setuservisiblehint function gets called , in v.findviewbyid code causes null pointer exception since setcontentview hasnt/ may not been called. proof if add 1sec delay setuservisisblehint code works properly. now want add server pull requests using parse, add data in list adapter , populate recyclerview after user views page so 1) should add code in setuservisisblehint , add 0.5secc delay gets executed after setcontentview called ensuring dont null pointer exception error or 2) there better way/ other functions can use achieve same? public class newsfeed extends fragment { linearlayoutmanager mlayoutmanager; boolean _arelecturesloaded=false; view v; progressbar bar; public newsfeed() { // required empty

i'm using python 3 process file produced microscope, collection of thousands of jpeg xr compressed images. need read of them memory. i'm reading data in binary mode, saving them in .jxr file , call jxrdecapp.exe convert tiff , read memory. apparently major bottleneck performance because involves lot of file read , write. from gather, imagemagick delegates task jxrdecapp.exe. using wand wouldn't help, either. right? then i'm wondering if there way decode jpeg xr in memory using python? thanks ! imageio ? it supports jpeg xr, , can read can read filenames, file objects, http, zipfiles, bytes, webcams.

what syntax in glmmpql multiple random effects? with glmer code looks like: fit<- glmer(a~b+c+ (1 | d)+ (1 | e), family = gaussian, data=data) how rewrite same exact thing using glmmpql ? i trying: fit<- glmmpql(a~b+c, random=c (~1 | d, ~1 | e), family = gaussian, data=data) but gives error. and major difference between glmer , glmmpql ? based on example provided, model glmmpql specified as: fit <- glmmpql(a ~ b + c, random = list(d = ~1, e = ~1), family = gaussian, data = data) afaik, major difference between glmer (which provided package lme4 ) , glmmpql (which relies on function lme , nlme pacakge) parameter estimation algorithm used in nlme not optimized dealing crossed random effects, associated sparse design matrix, while lme4 takes advantage of structure; see, e.g., pinheiro & bates, "mixed-effects models in s , s-plus", springer, 2000, pp. 163. further references on differences between lmer/glmer , lme usual: ht

i don't have clue start this. need casperjs run through 15 different pages, each page runs through needs data 150 different locations need set cookie values. each location, need check data 5 different dates. any 1 of these seems pretty straight forward, trying 3 happen confusing me. i tried set way: for(iterate through urls){ for(iterate through locations){ for(iterate through dates){ phantom.addcookie({ // cookie data here based on location , date }); casper.start(url) .then(function(){ // stuff here }) .run(); } } } essentially loop through everything, load page based on last link, @ last location, on last date. every other location gets skipped. there easier way this? perhaps better, there way tell javascript loop wait casper finish doing needs before jumping next loop iteration? i'm happy provide more details if needed. tried simplify process best can without cutting out needed info.

i'm working on gallery drag scroll trough images in gallery, similar this . the drag detection working fine, don't sliding of content work properly. detects dragging , manages set proper position, jumps beginning when drag again. this how function runs on drag looks like: dragcontent: function(e) { var delta = e.pagex - project.dragstartx; project.isie ? $('#gallery-content').css("margin-left", delta) : $('#gallery-content').css("translatex", delta); }, have @ jsfiddle have recreated problem. i think need save position content stops , somehow start position on next drag detected. want smooth easing example, still rolls bit on "mouseup". i'm hoping want share thoughts on how solve without using plugins. you need store current state of slider. right now, you're correctly calculating delta, distance mouse (or pointer) has traveled. you're setting delta margin, meaning start @ 0. i mo

i've been having consistent issue every =filter() function on spreadsheets stop working, display "n/a" "no matches found in filter evaluation". filtering data same sheet, not importing it. i have copy function, delete it, hit enter apply changes cell, paste in , hit enter apply function again. after work expected. this happens no rhyme or reason, , affects worksheets in document. how prevent this? there way automatically fix without copy/pasting functions dozens of times on regular basis? edit: function example =filter(organize!f2:k1000, organize!d2:d1000 = b6, organize!c2:c1000 =a6, (organize!e2:e1000 = "doug") + (organize!e2:e1000 = "rach owes doug")+ (organize!e2:e1000 = "both")+ (organize!e2:e1000 = "rach owes doug split")) this shows "n/a" "no matches found in filter evaluation" till delete , paste in.

so i'm teaching myself graph algorithms, on kruskal's, , understand it's recommended use union-find checking whether adding edge creates cycle takes o(log v) time. practical purposes, see why you'd want to, strictly looking through big o notation, doing affect worst-case complexity? my reasoning: if instead of union find, did dfs check cycles, runtime o(e+v), , have perform v times runtime of o(v^2 + ve). it's more union find, o(v * logv), bulk of complexity of kruskal's comes deleting minimum element of priority queue e times, o(e * loge), big o answer. don't see space advantage either since union-find takes o(v) space , data structures need maintain find cycle using dfs. so overly long explanation simple question: using union-find in kruskal's algorithm affect worst-case runtime? and understand it's recommended use union-find checking whether adding edge creates cycle takes o(log v) time this isn't right. using union find
