"stereo effect" isn't descriptive. assuming have stereo video files (one left eye, 1 right eye) you'd play them in left sphere (seen left eye), , right sphere right eye. spheres offset interpupillary distance (ipd) - 55mm. (it'd whatever stereo videos offset by). so, might ask - happens when turn around? ipd goes negative. when or down? goes zero. welcome stereo video. note there ways around this, you're not going them gopro without lot of special processing. @ best can sync idp direction averaged lens separation video streams, you'll stitching errors. equirectangular format (i.e square video) isn't best, you'll wrong answer @ poles. not using sphere how evolve (but it's simplest solution till better one)

i trying make navigation bar drop down menus. i've created navigation bar , used bootstraps "pull-left" class move left. dropdown menu have created using jquery moved left since html code contained in div marked "pull-left" have googled , tried out stuff few hours, couldn't quite find solution. the html navigation bar <div id = "nav"> <div class = "container" > <div class = "pull-left "> <img class = "logo-image" src = "logo2.png" /> </div> <ul class = "pull-left"> <li class "logo"><a href = "#">home</a></li> <li><a href = "#">about</a></li> <li> <a href = "#">projects</a> <ul> <li>&l

i implementing small spring mvc poc, , use jsf view technology since people in company used j2ee primefaces environment. does spring mvc 3 support jsf, or jsp? have read multiple articles mixing two. my need create appealing ui. there simple way using spring mvc jsp view technology? our application uses schedules/calendars in multiples pages. it's time management app you're making conceptual mistake. jsf not view technology. jsf mvc framework. spring mvc, albeit have both different ideology; jsf component based mvc , spring mvc request based mvc. full competitors. cannot mix them. should choose 1 or other. instead, jsp , facelets true view technologies. since java ee 6 (december 2009), jsp deprecated , replaced facelets (xhtml) default view technology jsf. you can use spring mvc jsp view technology . can use spring mvc facelets view technology (and many others ). can not use spring mvc jsf components let alone jsf component libraries primefaces. not makin

this question has answer here: how run node.js app background service? 23 answers i put node application on ubuntu server. started program using nodejs index.js now gives me "listening on *:3000" the problem ssh'd ubuntu server, cursor stuck under "listening" line. 1) how can close ssh session , leave node running? should have started node different user? 2) once close ssh session , node still running. how can stop node once ssh server? 3) ssh server , start run nodejs file, want other simple work unrelated sites on same server. since cursor stuck after "listening" line, how can go doing else? i suggest use screen program. screen terminal multiplexer, allows user access multiple separate terminal sessions inside single terminal window or remote terminal session (such when using ssh). it can started typing

going through php class file @ work found interesting snippet. script dynamically creating variable, dynamically checking if there active $_get[''] variable it's creating , if there it's loading $_get data , if it's not it's writing n/a variable it's dynamically creating. script continues on switch function same logic it's case breaks. 1.) safe? 2.) can attacked? 3.) there easier way this? 4.) why this? $switch_types = array("id","type","page"); foreach ($switch_types $key => $value) { $$value = $value; if(isset($_get[$$value])){ $$value = $_get[$$value]; } else{ $$value = "n/a"; } } this long-winded way write: $id = isset($_get['id']) ? $_get['id'] : 'n/a'; $type = isset($_get['type']) ? $_get['type'] : 'n/a'; $page = isset($_get['page']) ? $_get['page'] : 'n/a'; it

the use case have zip file containing many csv files. each line in each file sent seda queue processing. problem i'm having i'd know when every line has been processed seda queue perform other work. i'm not sure how approach this. currently, i'm investigating using polling test when seda queue empty, produce false results if lines processed faster arrive. code i have class unzips zip file , reads each file inputstream . each line in file sent producer in turn sent seda queue. @component public class csvprocessor { @resource(name = "csvlineproducer") producertemplate producer; public void process(inputstream flatfilestream) throws ioexception { if (flatfilestream==null) return; try { lineiterator = ioutils.lineiterator(flatfilestream, "utf-8"); while (it.hasnext()) { final string recordline = it.nextline(); this.producer.send(new processor() {

<c:foreach items="${list}" var="item"> <div class="block" id="${item.id}" style="background: black"></div> </c:foreach> is possible style div depends on current item.id avoiding jsp <c:choose> <c:when test="${ item.num == 0}"> inside div when first load page? item.num can 1 or 0. need this: if(item.num==0){ style="background: black" }else{ style="background: transparant" } why not use ternary operator? no need jquery here... <c:foreach items="${list}" var="item"> <div class="block" id="${item.id}" style="background: ${item.num==0?'black':'white'}"></div> </c:foreach> update if want correctly, try avoid inline styles , add css class instead. can define styles in separate file. <c:foreach items="${list}" var="

my question there 3 input text field , button, whatever user enters , press button, alert should how many negative numbers , how many positive numbers on text field? here working example code explained below. if want enter number in each of text field , click button tells number of positive , negative numbered entered here code, you html code, <input id="one" type="text"/> <input id="two" type="text"/> <input id="three" type="text"/> <input type="button" onclick="check();" value="check"> now can write script follows, function check(){ //converting values integer var x = parseint(document.getelementbyid("one").value); var y = parseint(document.getelementbyid("two").value); var z = parseint(document.getelementbyid("three").value); //initializing positive , negative count 0 var poscount = 0;

i trying build loop step through each site, site calculate frequencies of response, , put results in new data frame. after loop want able combine of site data frames like: site genus freq 1 50 1 b 30 1 c 20 2 70 2 b 10 2 c 20 but need names (of vectors, dataframes) change each time through loop. think can using sitenum variable, how insert new variable names? way tried (below) treats part of string, doesn't insert value name. i feel want use placeholder %, don't know how variable names. > sitenum <- 1 > (site in coralsites){ > csub_sitenum <- subset(dfrmc, site==coralsites[sitenum]) > cgrfreq_sitenum <- numeric(length(coralgenera)) > (genus in coralgenera){ > cgrfreq_sitenum[genusnum] <- mean(dfrmc$genus == coralgenera[genusnum])*100 > genusnum <- genusnum + 1 > } > names(cgrfreq_sitenum)

i have edittext view on relativelayout , , can capture soft input keyboard keycode keycode_enter (int 66) . key listener: myedittext.setonkeylistener(new view.onkeylistener() { @override public boolean onkey(view v, int keycode, keyevent event) { log.d("softinput", "key received!"); } }); the problem soft keyboard displays key labeled "next" , need display "done". when (successfully) change key "done" using api: myedittext.setimeoptions(editorinfo.ime_action_done); the key listener stops working , can no longer receive anything in key listener. logcat doesnt show anything. literally stops working. when remove above line of code, works again key displays "next". i guessing clearing other flag required notify keys, using editorinfo.ime_action_next works perfect, soft key, of course displays "next". anybody knows workaround this? or reasons why happens? thanks.
