that's use attempt. first pieces of adjustment work fine, visibility , color. position doesn't want adjusted. i tried $('#feedback_message_signup_final').css({"visibility": "visible", "color": "#347c17", "position": "absolute", "left":"22.8%"}); and this $('#feedback_message_signup_final').css({"visibility": "visible", "color": "#cc0000", "left":"25.8%"}); they different variables idea same , won't work in both cases. what's error? typically when run problems positioning (especially after elements have been display:none'd) -- comes initial dom render doesn't know actual width/height/position of invisible element be. seems rear head on me when use percentages instead of fixed pixels on these elements. can try fixed pixels instead of percentages?

i configured resterrorhandler in restclient: restclient.setresterrorhandler(restclienterrorhandler); but it's not called. i debugged code , see in generated restclient_ class resttemplate.exchange throwing exception, try catch calls resterrorhandler being generated response.getbody() , not entire method. is bug in androidannotations or doing wrong? i'm using androidannotations restclient inside robo spice request. thanks! this aa issue has been fixed today :) may use snapshot until release new version.

i have div 100% height, 70% viewport height, , overflow:scroll . now want create overlaying div touch devices can use scroll whole page instead of div . i created div position:absolute , full page height. if android users drag on div , whole page scrolls, expected. however, on ios7 underlying div scrolled, touch event goes right trough div . jsfiddle .scrolldiv{ width:100%; height:200px; overflow-y:scroll; border:solid 1px #f00; -webkit-overflow-scrolling: touch; } .pagescroller{ position:absolute; right:0; top:0; bottom:0; width:50%; background-color: rgba(0,0,0,0.7); } if use ios7 , drag on page div on scrolling div , scrolling div scrolled instead of page. does know solution this? on .pagescroller scroller element, add overflow-y: scroll; , -webkit-overflow-scrolling: touch; attributes, postive z-index . prevents scroll action reach "layer" beneath. .pagescroller{ position:absolute;

consider following use case: have quickcheck test suite consisting of 2 test cases prop_testcase1 , prop_testcase2 . using hpc can observe code coverage of test suite. however, i'd separate results coverage of prop_testcase1 , prop_testcase2 (to further process results). 1 way out run executable several times explicitly specifying test case command line argument , process generated tix file after each run. yet, prefer hide away logic in library. in reality run more 2 test cases. explicitly re-executing binary each test case seems rather inconvenient. @ same time i'd imagine hpc keeps coverage data in kind of intermediate data structure during program execution. question: there way recognize program has been compiled hpc symbols , somehow access data hpc generates @ runtime? i think found way achieve desired effect. required functions provided trace.hpc.reflect module. unfortunately documentation lacking. nevertheless, here minimal example seems work:

my app charges premium customers $x.00 per month, however, actions give customers credit against monthly subscription fee. example, if customer submits record database, given credit (stored in database). each credit earn give them $0.50 off of next month's subscription, however, if cancel subscription, not want seem owe them money (it should usable towards subscription fees). best way achieve through stripe api? if makes difference, using rails 4, ruby 2, stripe, koudoku subscriptions, , devise authentication. thanks! you want set app handle stripe web hooks if haven't done so. when new invoice created, if have web hook url set up, notify via hook , wait hour before processing payment. design setup want. when notified invoice has been created, if there credits user, create 1 or more negative invoice items represent credits. since aren't creating credits in stripe until right before payment processing, scenario of them canceling credit doesn't apply.

i want write surface view without creating thread. possible create surfaceview ,without calling thread. if possible, please provide me simple example. your question doesn't entirely make sense me, i'll try answer think you're asking. yes, can draw on surfaceview without creating dedicated thread. not recommended approach; should rendering off main thread app doesn't become slow respond, it's not absolute requirement. i don't know if counts "simple" example, grafika's "multi-surface test" draws on 3 overlapping surfaceviews ui thread. these static images, drawn once, there's not need separate thread. if start animation on 1 of surfaces (with "bounce" button) kicks off new thread, because it's easier manage way.

i trying figure out if there way avoid unchecked cast in function (using java 7): private static <o> valuevalidator<o> newforalways(always valid_orinvalid) { @suppresswarnings("unchecked") valuevalidator<o> vldtr = (valuevalidator<o>)(valid_orinvalid == always.valid ? newforalwaysvalid() : newforalwaysinvalid()); return vldtr; } here signatures of 2 functions being returned: private static <o> valuevalidator<o> newforalwaysvalid() { private static <o> valuevalidator<o> newforalwaysinvalid() { (and here's always enum, boolean substitute: enum {valid, invalid;}; ) all 3 functions have same return type , contain unbounded generic. these 2 questions explain why happens, although both bounded generics: why doesn't ternary operator generic types bounded wildcards? generics compilation error ternary operator in java 8, not in java 7 so though works valuevalidator<integer

i'm having issue android maps v2 displaying blank screen of users. have 100k users using app, there small percentage complain can not see app (blank) no matter do. have had them restart app , clear google play store data in hopes it'll work. i have looked @ logs(snippet below) , see classic "authorization failure". @ first thought perhaps user did not have valid internet connection, i'm checking online, plus make web calls work. suspected did not have google play services installed/enabled, do. questions: 1. there problem using android maps v2 api in other countries not know about? 2. suspected @ 1 point these users have proxy in place, google prevent downloading map under conditions? 3. see "04-06 14:57:19.804 e/googleplayservicesutil( 7295): google play services resources not found. check project configuration ensure resources included." in logs well, have read in several locations ignore error. should more that? 3. i'm fresh out of ideas,

i have 2 d classes in 1 module. class have property, can accessed class , class b. how this? class { int = 5; // make accessible to, , to, b. } class b { this(in pa) { int b = pa.a; } } private private module, not class. so, marking symbol private makes stuff in module can access it. package makes stuff in same package can access symbol. protected makes stuff in class , in classes derived class can access symbol (unlike others, protected makes no sense outside of classes). public makes can access symbol. private , package functions never virtual, whereas protected , public functions virtual unless compiler able determine don't need (which @ point, can pretty happen when function final , doesn't override function in base class). so, long 2 classes in same module, , members private, can access each others members - can else within module - nothing outside module can access them. there no way restrict access within module e

i'm still learning sml, apologies if rather dumb question. wondering if there better way pattern matching on constructs outside of functions. for example, let's have type type coord = int * int * int and have value b of type coord . understand can pattern matching in functions, example: fun get_x_coord ((x, y, z) : coord) = x but let's we're working b inside of function not given parameter. feel doing case b of (x,y,z) => (* stuff *) is rather clunky if have single result want (for example know there 3 integer values , want isolate them). is there better way this? sure - can use pattern matching in val -bindings too, this: fun foo (b : coord) = let val (x, y, z) = b in (* stuff *) end

what faster realtime game server, 1 port per user on server in each user passed thread , receives port assignment, or 1 port per user in each thread handed socket after being established on main thread? it's not question of 'faster'. once connection established doesn't matter. real issue first alternative not implementable without lot of code in slow things down in connect phase. tcp server socket listens on single fixed port clients know about, , connect port. if want move them port have open it, tell them port is, , accept connection. it's pointless.
