is possible index of checked input, of them nested in different divs. eg such situation: <div class="parent"> <div> <input></input> <input></input> <input></input> </div> <div> <input checked="checked"></input> <input></input> <input></input> </div> </div> so checked input show index = 3 how build such selector? possible? or can show index of children nested directly withing same parent? try invoke .index() on entire collection passing target element, var inputs = $(".parent input:checkbox"); var index = inputs.index(inputs.filter(":checked")); //3 demo a demonstration valid html given here .

i have arduino project using nrf24l01+ radio module on spi (using library: http://tmrh20.github.io/rf24/ ) , rfid reader on softwareserial. sleeping arduino , having them wake via interrupt when message has been received or rfid tag ready read. rfid on pins 4 , 5, while nrf covers pins 9 - 13 number 2 interrupt. both of these modules work fine sleep , interrupt code separately, when combined in single sketch, arduino wake due rfid tag, read it, try send on radio , hang, waiting library call write() return. i have delved bit 2 libraries, can't make heads or tails of softwareserial library. seems maybe using same isr behind scenes nrf module, don't see why should big problem, , don't understand why should cause radio hang. i know may long shot, have idea might going on? maybe knows these libraries? thoughts on work around? thanks. i experiencing same symptoms, , problem turned out buffer overrun in code. overrun due softwareserial dropping bytes because rf

i've watched many videos , tutorials on mongodb , mongoose, , while think mongoose it's job well, isn't contradictory flexibility nosql datastore offers? being schema-less environment. what if want add new property, or array document? have update mongoose schema correct? seems counter-intuitive whole point of flexible document store. if want application more flexible, isn't mongoose wrong choice application? disclaimer: i've been using mongoose 2 years in large enterprisey application, , have been using mongo year on top of pre-mongoose. the docs mention let's face it, writing mongodb validation, casting , business logic boilerplate drag. that's why wrote mongoose. this statement hard appreciate unless you've been through pain. here's dream: application perfect, , store need in 1 collection. can throw data or fetch it. fits linux pipeline , works! i think reality underestimate our data at least relational , implicat

here problem: there number of arrays, example, 2000 arrays, 256 integers in each array. , range of integers quite considerable, [0, 1000000] instance. i want unique elements each array, in other words, remove duplicate elements. have 2 solutions: use thrust unique element every array, have 2000 times thrust::unique . each array pretty small, way may not performance. implement hash table in cuda kernel, use 2000 blocks, 256 thread in each block. , make use of shared memory implement hash table, every single block produce element-unique array. the above 2 methods seem unprofessional, there elegant ways solve problem cuda ? you can use thrust::unique if modify data similar done in question: segmented sort cudpp/thrust for simplification, let's assume each array contains per_array elements , there total of array_num arrays. each element in range [0,max_element] . demo data per_array=4 , array_num=3 , max_element=2 this: data = {1,0,1,2},{2,2,0,0},{0,0

i cannot find answer question, example can have optional of optional of string? tried write small test check out: let : string? = nil; let b : string?? = a; if b!=nil { // error println("has value"); } else { println("fail"); } but since not swift programmer don't know error saying "cannot assign result of expression". yes can; syntax incorrect though. line: if b!=nil is digested compiler as: if (b!) = nil ... thinks you're trying assign nil unwrapped optional. swift doesn't allow make assignments within if statements (in contrast objective-c). instead clearer: if b != nil edit: and, finish thought, proving syntactic sugar making optional optional, if add: if let b = b { print("\(b)") } you should see nil printed output.

i wonder if there efficiency difference between using if statement or switch. example: if(){ \\code } else if(){ \\code } else{ \\code } i believe program needs go , check of if statement if first if statement true. switch(i){ case 1: //code break; case 2: \\code break; but in switch, there break command. approaching right? if not, explain efficiency difference between them? switch perf better if else in case of switch there 1 time evaluation . once evaluated switch knows case needs executed in case of if else has go through conditions in case of worst scenario. the longer list condition, better switch performance shorter list (just 2 conditions), can slower also from why switch faster if with switch jvm loads value compare , iterates through value table find match, faster in cases
