is there mechanism provide server push technology using plain html, without using javascript (or other script languages on client side). under "server push" mean process server update part of page content when needed. i don't know of way true server push can used without javascript in page. without javascript, thing i'm aware of meta refresh tag tell browser refresh page after particular time interval. tag applies whole page only. if wanted part of page updated, use iframe , have iframe updated. of course, not server push, client-driven auto-update , run on predetermined interval, not when there new data. smarter this, need javascript. the efficient server-push use javascript page connect server on websocket , have server send data page via websocket whenever wants (true server-push). client's javascript can respond receipt of websocket data updating particular piece of page.

i have setup android project through sbt (0.13.1) in idea 13.0.2. mixed java 7 , scala 2.10.3. uses sbt support in idea. even though in build.sbt have following: scalacoptions += "-target:jvm-1.7" javacoptions ++= seq("-source", "1.7", "-target", "1.7") here result when make project idea: java: javactask: source release 1.7 requires target release 1.7 any please? finally solved. you need this: javacoptions in compile <<= (javacoptions in compile) map { _ collect { case "1.5" => "1.7" case s => s } } i suppose due fact, default javacoptions supplied plugin 1.5, , adding setting doesn't work, replacing it.

a processor has 4 cores each core has 2 - hyper threads its clock frequency 2 ghz on average, instruction needs 4 cpu cycles execute on each hyperthread how many instructions can execute in 1 second? need equations use. know 1 ghz has 1 cpu cycle @ 1 nano second therefore 2 ghz 1 cpu cycle in .5 nano seconds. well, i'll started, it's basic math problem. 2ghz - frequency, in [cycles/second]. 4 - instruction duration, in [cycles/ops]. so 2ghz [cycles/second] / 4 [cycles/ops] = 0.5ghz [ops/second] . note cycles unit cancels out , "feels right" because we're left units being asked :) do similar math account hyper-threads , cores - multiplication. (you can carry through units, e.g. [ops*threads*cores/second] , can dropped in context of answer asking ops/second across all v-cores.)

im trying using continually running thread perform tasks @ high rate in app. in app have list of 1000 or time stamps. poll them until it's time , instruct ausampler play. the problem have seem fundamentally not understand how nsthread works. in simple example below cpu shoots 100% despite no tasks being run. in way using nsthread incorrectly? better way create a fast polling mechanism doesnt hog cpu? mythread =[[nsthread alloc]initwithtarget:self selector:@selector(test) object:nil]; [audiothread setthreadpriority:0]; [audiothread start]; -(void)test { while(mycondition) { // work // cpu == 100% } } the solution find minimum interval between sampler fire times (based on bpm/ resolution) , make thread sleep amount.

i've looked high , low around web looking answer question answers don't quite give me i'm looking for... i have e-commerce site i'd add share button order confirmation page that, when clicked, shares specific product have purchased. how go doing this? each product needs have unique url in order shared. url use when generating share button. when implementing share button , you'll need javascript sdk (as mentioned in link) , once have that, you'll need have html on page: <div class="fb-share-button" data-href="http://your-product-url" data-type="button_count"></div> the data-href attribute want dynamic , swap out each product want share.

basically want attach .mdf file located in d(you can see picture), got error. idea why happened , how fix it? there may 2 solutions that 1) may start sql server management studio application right clicking , selecting "run administrator" run , try attach database in d: 1) may put database in default directory of database c:\program files\microsoft sql server\mssql10_50.mssqlserver\mssql\data etc ....

say have set d of multisets: d = { {d, g, o}, {a, e, t, t}, {a, m, t}, } given multiset m , like m = {a, a, m, t} i algorithm f give me elements of d subsets (or more precisely, "submultisets") of m : f = {{a, m, t}} if 1 such query, scanning on elements of d (in o(#d) time) optimal. if want answer many such queries same d , different m , might able make faster preprocessing d smarter data structure. we toss of d hashtable , iterate on possible subsets of m , looking each in hashtable, that's o(2^#m) . fine small m , not fine medium large m . is possible in polynomial time in #m ? or maybe reduce known np-complete problem one, prove it's impossible fast? edit: realized in worst case, need output of d , #d still going appear in time complexity. let's assume size of output bounded constant. here quick implementation of ternarysearchtree (tst) can in problem. number of years ago, inspired article in drdobbs. can read more...

i'm new angular , have ng-grid table. want save clicked elements in array (so elements uniquely correspond table cells) , strike cells through, in array. has happen in "toggleable" way. so far cells like: <div ng-click="myfunc(args)" ...><span>text</span></div> and myfunc takes care of array, in factory. did dom manipulation same function thought angular way should create directive span element, evaluates array , depending on whether object corresponds cell containing particular span css class attached. fyi: elements in array contain coordinates of cells (x,y), stored interaction server. bind array scope , use ng-class syntax bind class matching condition. condition not straightforward, wrote function evaluate condition , works fine ng-class

i've added player* _player pointer helloworldscene scene in cocos2d-x v.2.2.2. i've defined class player : public cocos2d::object , it's referenced counted. create method helloworldscene looks scene* helloworldscene::createscene(player* player) { auto scene = scene::create(); auto layer = helloworldscene::create(); layer->_player = player; player->retain(); scene->addchild(layer); return scene; } where player instantiated in appdelegate::applicationdidfinishlaunching() . now, since i've retained _player (and feel nice guy today), i've decided release well: helloworldscene::~helloworldscene() { if (_player) { _player->release(); } } so far good. however, when helloworldscene popped, following called void director::popscene(void) { ccassert(_runningscene != nullptr, "running scene should not null"); _scenesstack.popback(); ssize_t c = _scenesstack.size(); if (c == 0) { end(); } else ...

i understand interface command can used pass a function subroutine. example in main program i'd define function , pass subroutine like: mainprogran use .... implicit none type decorations etc interface function test(x,y) real, intent(in) :: x, y real :: test end function end interface call subroutine( limit1, limit2, test, ans) end mainprogram is correct way of doing this? i'm quite stuck! within subroutine there need put let know function coming in? subroutine in case library don't want have keep recompiling change function. module: module fmod interface function f_interf(x,y) real, intent(in) :: x, y real :: f_interf end function end interface contains function f_sum(x,y) real, intent(in) :: x, y real f_sum f_sum = x + y end function function f_subst(x,y) real, intent(in) :: x, y real f_subst f_subst = x - y end function subroutine subr(limit1...

i'm running windows 2012 r2 server set in november 2013. while started getting warnings icon in notification area informing me "[the] remote desktop service trial period end in x days". warning pops every time or of co-workers connect machine in question. has me bit puzzled. @ first, assumed wouldn't have worry it, deadline comes ever nearer, i'm growing bit concerned. do need "remote desktop service" in order connect machine remote location or can still manage machine after trial period expires? physical location of server in question makes troublesome me manage without form of remote desktop tool. thanks in advance! yes. there licensing specific rds on servers. check microsoft online , should able tell required.

in unity3d i've got script adds variable 'eaten' component. using unityengine; [addcomponentmenu("my game/iseaten")] public class iseaten : monobehaviour { public bool eaten; } yay! can add script access 'eaten' using unityengine; using system.collections; public class test : monobehaviour { private eaten somescript; // use initialization void start () { somescript = getcomponent<iseaten>(); bool temp = somescript.eaten; print(temp); // false } } which works fine. have access variable dot notation script? ie if (mycube.eaten == true) { // } you know, in unity 1 create whole script add single property object. common approach think of scripts 'components' (which are, in fact). let me explain this, component single piece of code add functionality gameobject , ability animate, or behave laws of physics. so, maybe, better reform iseaten class form true component, pi...
