i have spring 3.0 webmvc application running on tomcat 7. on application startup kick off background thread load in-memory cache records db. thread typically takes on hour load data db. in same application have @controller annotated class exposes rest interface clients can objects loaded cache. one of our requirements rest requests made prior data load being finished return service_unavailable (503) http code client immediately. accomplish set simple check of boolean flag each request method in controller makes before doing work. if value false method should return 503 code. loader thread set flag true once completed load allow request methods function normally. the problem background thread seems causing http requests sent controller timeout after 30 seconds instead of hitting flag , returning 503 code client. i'm not expert in tomcat threading issues , wonder if i'm doing wrong when creating long running background thread? using "implements runnable" method

in c# form i'am trying make nicely looking button cant on text "padding" problem. problematic button desired button i made mind of how should can't achieve it. supposed flat button black borders , "options" text in (like on second picture). kind of "padding" hides pretty big part of text. changing font size kinda helped want perserve button's ~16px height , font small can fit in there unreadable. i've tried setting button's padding property 0. thinking workaround overriding onpaint event / making multiple controls (like, combine label) i'am worried performance impact. hm took shot @ it, best do. i used image flat button, border providing grey area beyond black border. sort of workaround. whatever. here image button background . and code button: // // button1 // this.button1.backcolor = system.drawing.color.fromargb(((int)(((byte)(64)))), ((int)(((byte)(64)))), ((int)(((byte)(64))))); this.button1.b

i wondering how can process array each value returns promise in same order they're specified. example, let's want call multiple ajax calls in order: var array = [ 'http://example.org', 'http://otherexample.org', 'http://anotherexample.org', ]; there's basicaly same question: how can use rxjs hold off requests ajax call until previous 1 resolves , suggests using flatmapfirst . since i'm using angular2 ( beta-15 @ moment) in typescript uses rxjs@5.0.0-beta.2 found out flatmapfirst has been renamed exhaustmap . but operator isn't listed in observable.ts , therefore can't use it. it's not present in bundled version of rxjs https://code.angularjs.org/2.0.0-beta.15/rx.js . so, how supposed use it? or there other way need? package.json lists lot of build scripts, should force use 1 of them? edit: should mention i'm using reactivex/rxjs library, not reactive-extensions/rxjs operator concatmap() d

i new react . i writing component arrayinput contains multiple(based on state) input box. and arrayinput need handle each input box's onchange event. i hope specific props/attribute (in case , "index") on these dramatically generated input box i search many posts , docs can't find correct way. i know can use this.ref[inputboxref] (react 14+) actual dom node , find has no "attribute" or "data" when using $(domnode).attr('index') or $(domnode).data('index') . window.arrayinput = react.createclass({ ......other methods handlechange:function(ref,event){ var dominputbox = this.refs[ref]; //trying index attribute of input } render:function(){ var self = this; return ( <div classname="input-wrapper" > <label&g

trying port app ionic 1 ionic 2, got few queries: how can setup push/pop pages links work when click on image, rather button? do background images still work same ionic 1, doesn't seem work in ionic 2? what correct way paste entire css ionic app, rather seperate bits in ionic 2 compile scss files? how can comment out typescript? have tried /* , how list of products stored in factories.js used , imported in ionic 2? jsfiddle(dot)net/vgthumsm/ where controller code , js functions underneath pasted .ts file? jsfiddle(dot)net/qov7bh0w/ in order push (or pop) page on navcontroller stack, need respond event in code afaik. background images should work fine using css. app/theme/app.core.scss best bet comments work same javascript comments. // line commented /* commented out stuff on several lines */

for computer simulate system of n particles in universe interact each other, 1 use rough algorithm: for interval dt=10ms each particle in universe each particle b in universe interact(a,b,dt) each particle in universe integrate(a,dt) it heavy, calling interact n^2 times per tick - thus, unfeasible simulate many particles. of time, though, particles near interact less strongly. idea take advantage of fact, creating graph each node particle , each connection distance. particles near interact more particles far. example, for interval dt=10ms each particle in universe each particle b 0m <= distance < 10m interact(a,b,dt) interval dt=20ms each particle in universe each particle b 10m <= distance < 20m interact(a,b,dt) interval dt=40ms fro each particle in universe each particle in b 20m <= distance < 40m interact(a,b,dt) (...etc) interval dt=10ms each particle in universe integrate(a,dt) this super

this has been driving me nuts. when load page initiate window.onfocus function: initializefocusdetecttor: function () { window.onfocus = function () { var options = { usefade: false } $.overwatch.worker.getview("/overwatch/updatewatch", function () { $.overwatch.init(); }, options); } } however don't want behavior on every page don't know how remove/reset this. i have tried window.onfocus = null; window.onfocus = function(){return;}; window.onfocus = ""; but not work if change use jquery event handling, can remove (e.g. off ). initializefocusdetecttor: function () { $(window).on('focus.mine', function () { var options = { usefade: false } $.overwatch.worker.getview("/overwatch/updatewatch", function () { $.overwatch.init(); }, options); }); }); // condition - turn off $(window).off(&
