a site i'm working on displays large number (>50) of complex svg images in scrolling dialog window. when viewing site in chrome, scrolling performance of dialog window poor - noticeably laggy , slow. however, if replace svg images png images, scrolling smooth , responsive. here's demonstration of difference: https://jsfiddle.net/nathanfriend/42knwc1s/ why svg scrolling performance worse png scrolling performance? after browser renders svg image, assume doesn't need rerender image until image manipulated in way (like resizing). scrolling element contains svg images cause images rerendered every frame of scroll animation? ` i think kind of chromium bug, i've found issue on so, because started experiencing on mac. works ok on opera instance. i don't think here able explain why it's slow if bug. i've created chromium bug, please star if want is...

here question. 1. intro a shapefile in polygon type represent study area http://i8.tietuku.com/08fdccbb7e11c0a9.png some point located in whole rectangle map http://i8.tietuku.com/877f87022bf817b8.png i want test whether each point located within/out polygon , further operation(for example, sum grid point amount within study area) 2. idea i have 2 methods information on stack overflow. 2.1 idea rasterize shapefile raster file , test. i haven't done yet, have asked 1 question here , answer. 2.2 idea b i have tried using poly.contain() test scatter point's location, result wasn't match reality. 3. code based on idea b: for example: original data represent pt (a pandas dataframe) contain 1000 grids x,y. shapefile shown study area, want filter original data leaving point within area. 3.1 preparation # map 4 boundaries xc1,xc2,yc1,yc2 = 113.49805889531724,115.5030664238035,37.39995194...

i build c# project on travis-ci like this : # .travis.yml before_install: - sudo apt-get update -qq - sudo apt-get install -qq mono-devel gtk-sharp2 install: - xbuild source/pash.sln travis uses precise (ubuntu 12.04 lts) seems choice them, includes mono 12.10. c# project hits bug in mono 2.10. bug appears fixed in mono 2.11+. i read ubuntu slow pick new builds of mono because depends on it, , can break much. that's fine, travis dependencies aren't problem - machine goes away @ end of build! i have considered compiling new mono in .travis.yml don't want put burden on travis servers. building mcs (mono c# compiler) fix. downloading , installing newer mono somewhere (where?) checking recent mono in git repo. suggestions? if you're going use higher standard distro packages provide, recommend go way , not use unstable 2.11.x series, official/beta 3.x ones. so, grab preview debian/ubuntu 3.0.6 packages ppa: http://www.meebey.net/pos...

i want upload csv file , insert db after huge validation , process. using fibers asynchronous call. fiber process keep executing fiber returns future.wait(); . meteor.methods({ uploadcsv: (calender) { if (meteor.isserver) { var future = npm.require('fibers/future'); var future = new future(); calender = parse(calender); future["return"](savecalender(calender)); //huge process , validation console.log(future); // { value: 1, resolved: true } return future.wait(); } } }); savecalender function executes every time. did missed stop fiber execution or how stop fiber execution?

i'm using libgdx create game got problem: how make sprite move 1 location marked click location marked click? need smooth animation. here's code have done: main application implements applistener , inputlistener. public class lgame implements applicationlistener { public static field field; private spritebatch bat; private listener listener; @override public void create() { field = new field(); bat = new spritebatch(); listener = new listener(); gdx.input.setinputprocessor(listener); } @override public void render() { bat.begin(); bat.draw(field.gettexture(), 0, 0); for(int = 0; <= 31; i++) if(!field.getfigure(i).iseaten()) bat.draw(field.getfigure(i).gettexture(), field.getfigure(i).getposx()*64, field.getfigure(i).getposy()*64); bat.end(); } "render" method iterate collection "field" contained objects on scene. public class listener implements inputprocessor { private int inx; private i...

let's have function takes 2 parameters, regular variable , function. function example(vara, function(){ //do vara? }) can use vara in definition of anonymous function? if run function , pass in vara, anonymous function know vale of vara is? answer no! your definition incorrect. function example(vara, function(){ //do vara? }); during function definition, not know callback , should be: function example(vara, callback){} now in following example: function test(vara){ function notify(){ console.log(vara); } notify(); } test(10) vara accessible because in same scope, if this: function test(vara, callback){ callback(); } test(10, function(){ // throw error, because there no variable called vara console.log(vara); }) and have pass arguments callback. function test(vara, callback){ callback(vara); } test(10, function(vara){ console.log(vara); })

i saw elegant , neat animation on site: http://adam.co/ notice how 'i making great ideas happen' comes view. trying figure out how that. could guide me on how produce similar effect website? it simple without libraries etc.. can pretty done css3. apply 'loaded' class or when page loads , define animation animate width (or scalex) , background positions. @-webkit-keyframes flip-in { 0%{ background-position: 5px -80px; -webkit-transform:scalex(0); } 50% { background-position: 5px -80px; -webkit-transform:scalex(1); } 100% { background-position: 5px 5px; } } .loaded #text-block { -webkit-animation-name: flip-in; -webkit-animation-duration: 0.75s; -webkit-animation-timing-function: ease-in-out; } take (i put webkit styles in example, use chrome or safari): http://jsfiddle.net/adamco/guju4/ the staggered effect simple enough too. can reuse same animation , incr...

in current application user can have "prepaid" amount of money on account. value stored in cents. in case of user tries transfer money 1 account should able use values like: "1,53", "1.53" , "1". need check if entered amount below amount he's able transfer. if (($request->amount * 100) <= $user->calculateamount()) the function $user->calculateamount() returns values example "351" stands 3,51€ (saved in cents). know problem ",", using "." works fine, user should able use both. there better way or did need use str_replace()? you can use this: http://codepad.org/nw4e9hqh currently there no other method parse float.
