i have 2 ways use model generated entity framework. can not find use when , why. method 1 odataqueryoptions<key_result> options (passed function argument) private odataquerysettings settings = new odataquerysettings(); iqueryable<key_result> result; try { result = options.applyto(dataaccessfunction.key(keyids), settings) iqueryable<key_result>; } method 2 iqueryable<log> result; try { result = accessmodel.log; } so far, have used them in code without knowing correct or why both used. can't find material me too. also, first 1 using in odata endpoints created using table valued functions in sql while second 1 using endpoints created using simple tables , views. but if entity framework consistent, shouldn't matter. , should able use 2 approaches interchangeably. can used interchangeably, difference makes them preferred 1 situation (table value

i trying find width , height of screen none of ways have tried work in class created, code below. does know how find it? cannot use way trying below because .getwidth() deprecated? public class crate { public int acrosscrate; public int updowncrate; context thecontext; windowmanager wm = (windowmanager)thecontext.getsystemservice(context.window_service); display display = wm.getdefaultdisplay(); int width = display.getwidth(); public crate() { acrosscrate = 650; updowncrate = 650; //int width = ; //int height = ; } } use below code private int getscreenheight(context context) { int height; if (android.os.build.version.sdk_int >= 13) { windowmanager wm = (windowmanager) context.getsystemservice(context.window_service); display display = wm.getdefaultdisplay(); point size = new point(); display.getsize(size); height = size.y; } el

i have: <div id="alerts"> <div class="alert">alert 1</div> <div class="alert">alert 2</div> </div> and want remove these alerts one-by-one after 4000 ms interval of 500 ms in pure javascript . i have this: window.onload = function(){ alerts = document.getelementbyid( 'alerts' ); if( alerts ){ alert = alerts.getelementsbyclassname( 'alert' ); settimeout( function(){ for( var i=0; < alert.length; i++ ){ ( function( ){ settimeout( function(){ alerts.removechild( alert[i] ); }, 500); } )(i); } }, 4000); } } i think not right way of using settimeout . the getelementsbyclassname returns live collection means when selected element removed or changed in dom referred collection changes. so in example when

suppose user of parent shell foo . if run sudo -u bar -i , in child shell user bar . so, how can find out user of parent shell inside child shell? namely, in case above, how can know user of parent shell foo ? update understand that, hack, possible achieve using ps . however, more interested in less hacky , more standard way, if possible. update 2 answers, resorted following solution: # parent shell, user foo $ sudo -u bar -i parent=foo # child shell, show parent user foo $ ps u -p $ppid | grep parent | cut -d= -f2 you can use $ppid variable assist along command or two: #!/bin/bash user=`ps u -p $ppid | awk '{print $1}'|tail -1` echo $user

the following 2 gql queries work: select * customer firstname = "john" select * customer rating > 4.0 but, when combine them... select * customer firstname = "john" , rating > 4.0 ... empty result set though running queries individually finds entity looking for. how compare more 1 property? here's i've done: i made sure @ least 1 entity exists both true. i created index properties: patrick costello @ google answered question: you need index on (firstname, rating). current index cannot answer query. basically, problem created index on properties. however, each "type" of query (in case, query comparing firstname , rating) needs own index (i.e. index firstname , rating). hope helps someone!

i'm trying create variable when call or use variable, runs function stuff , return variable. example make more sense: def establish_client(): = none if true: = 'a' return >>> print establish_client 'a' it possible this? there way of running method , returning without using parenthesis? in general case: no. but there techniques might come close. properties allow members in object. class demo(object): @property def establish_client(self): = none if true: = 'a' return d = demo() print d.establish_client but properties don't work local or global variables. also can use __str__ string conversion, works when need behavior when variable used in way converts string. not case. see mescalinum answer how that.

this question may seem silly cannot find way solve myself. need multifold integrations (at least 4 fold) range infinite matlab, , did not found suitable functions. for example, how should following integral: integrate[f(x,y,z,w),{x,-\infty,\infty},{y,-\infty,\infty},{z,-\infty,\infty},{w,-\infty,\infty}] where function f may defined as f=1/(x-y)*1/(z-w) exp(-0.25 (x^2+y^2+z^2+w^2)) in matlab, 1 needs add dot behind arguments function can executed, confused about. i appreciate if help. i assume mean symbolic integration. that define symbolic variables . define function of symbolic variables. apply int repeatedly integrate respect each variable. assumes function satisfies hypotheses of fubini's theorem (which example function). so: >> syms x y z w %// step 1 >> f = exp(-x^2-y^2-z^2-w^2) %// step 2 f = exp(- w^2 - x^2 - y^2 - z^2) >> f = f f = exp(- w^2 - x^2 - y^2 - z^2) >> f = int(f,
