javascript - Optimum Location for Code Schools -

-

this taken code wars, not looking cheat or anything. have pretty solved problem i'm unsure if method of determining constitutes best location correct.

var optimumlocation = function(students, locations){   //your solution   var listoflocations = [];     (var key in locations) {     var obj = locations[key];     var totaldistance = 0;     (var = 0; <= students.length-1; i+=1) {       console.log(students[i]);       var location = calculatedistance(students[i],[obj.x, obj.y]);       totaldistance += location;     }      listoflocations.push({id:parseint(key), dist:totaldistance});    }    listoflocations.sort(function(a,b){       return a.dist - b.dist;   });    console.log(listoflocations);   var id = listoflocations[0].id;   return "the best location number " + (id +1) + " coordinates x = " + locations[id].x + " , y = " + locations[id].y; }  function  calculatedistance (loc1, loc2) {   var distx = math.abs(loc1[0] - loc2[0]);   var disty = math.abs(loc1[1] - loc2[1]);     var distance = math.sqrt(distx*distx + disty*disty);    return distance;  };

for first test case 

optimumlocation([[3,7],[2,2],[14,1]],[{id: 1, x: 3, y: 4}, {id: 2, x: 8, y: 2}]);

everything fine.

but second test case

optimumlocation([[152,7],[1,211],[14,56],[12,4],[142,7]],[{id: 1, x: 63, y: 55}, {id: 2, x: 55, y: 21},{id: 3, x: 144, y: 12}]);

the correct location location 2 function thinks location 1. method of using least total distance students travel, location 1 has lowest , therefore should optimum solution on location 2.

any appreciated.

i have managed figure out myself. wondering, on complicated problem. question stated students walk in straight lines, not diagonally. instead of using pythagoras theorem, had add x , y distances find total distance.

yii2 - Yii 2 Running a Cron in the basic template -

-
i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
