i'm using jquery live filter plugin: (function($){ $.fn.livefilter = function(inputel, filterel, options){ var defaults = { filterchildselector: null, filter: function(el, val){ return $(el).text().touppercase().indexof(val.touppercase()) >= 0; }, before: function(){}, after: function(){} }; var options = $.extend(defaults, options); var el = $(this).find(filterel); if (options.filterchildselector) el = el.find(options.filterchildselector); var filter = options.filter; $(inputel).keyup(function(){ var val = $(this).val(); var contains = el.filter(function(){ return filter(this, val); }); var containsnot = el.not(contains); if (options.filterchildselector){ contains = contains.parents(filterel); containsnot = containsnot.parents(fil

i'm new in android. i'm having problem right now. app crashes when starting 3rd activity here code package com.example.anagramgame; import android.app.activity; import android.os.bundle; import android.database.cursor; import android.widget.toast; public class level_list extends activity{ @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.level_list); dbadapter db = new dbadapter(this); db.open(); cursor c = db.getallquestions(); if(c.movetofirst()) { { displaytitle(c); }while (c.movetonext()); } db.close(); } public void displaytitle(cursor c) { toast.maketext(this, "id: " + c.getstring(0) + "\n" + "answer: " + c.getstring(1) + "\n" +

so made query: db.zips.find( { loc : { $geowithin : { $box :[ [ -90 , 30 ] , [ -80 , 40 ] ] } } } ) and here 1 (out of many) outputs: { "city" : "apison", "loc" : [ -85.016404, 35.014926 ], "pop" : 1614, "state" : "tn", "_id" : "37302" } my question how able sort population , limit 10? when try {$sort{pop:1}} errors doesn't know pop, when add {$limit:10} @ end or query doesn't limit 10 entries shows me last column. any appreciated! db.zips.find({loc:{$geowithin:{$box:[[-90,30],[-80,40]]}}}).sort({pop:1}).limit(10)

i have interface, resource , supposed wrap something , expose few operations on wrapped object. first approach write following, strategy pattern in mind. interface resource<t> { resourcestate read(); void write(resourcestate); } abstract class abstractresource<t> implements resource<t> { // strategy comes in. protected abstractresource(resourcestrategy<t> strat) { // ... } // both read , write implementations delegate strategy. } class exclusiveresource<t> extends abstractresource<t> { ... } class shareableresource<t> extends abstractresource<t> { ... } the 2 implementations above differ in locking scheme used (regular locks, or read-write locks). there resourcemanager , entity responsible managing these things. idea of usage client, be: resourcemanager rm = ... mycustomobject o = ... mycustomreadwritestrategy strat = ... rm.newresourcefor(o, "id", strat); this way, client know
