javascript - Displaying Special Case Of Sorted Firebase Arrays (with AngularJS) -


so have set of clubs, , set of users. each club , each user has specific latitude , longitude. showing clubs user easy ng-repeat, i'm trying show clubs within distance of each user. i've come far:

var arr = []; $scope.clubs.$loaded().then(function() {     angular.foreach($scope.clubs, function(value, key) {        if($scope.getdistance(value.lng, value.lat) == true) {         console.log(value.name + " it's close enough!");          arr.push( {id: value.$id, description: value.description, name: value.name});        }     });     console.log(arr); }); $scope.narr = arr;

is there more elegant way this? i'm singling out data firebase array, , putting smaller array (arr) , ng-repeating through it. it's not firebase array... ideas?

p.s. don't think can use of built in firebase sorting, because distance unique each user, , each location requires latitude , longitude.

why not evaluate $scope.getdistance() in template?

you'll need create $firebasearray() on $scope.

$scope.cabyns = $firebasearray(ref);

then in template can call $scope.getdistance() item in ng-repeat. using ng-if direction, can state whether should loaded.

<ul>   <li ng-repeat="item in cabyns">      <span ng-if="getdistance(item)">       {{ item.name }}     <span>    </li> </ul>

another thing try doing using geofire if you're doing geofencing.

java - pagination of xlsx file to XSSFworkbook using apache POI -

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
