question: write single method declaration can accept both list<int> , int[] my answer involved this: void testmethod(object param) // object base class can accept both int[] , list<int> but not intended answer, said so. any ideas how method signature ? you can use ilist<int> both, int[] , list<int> implement: void testmethod(ilist<int> ints) on way can still use indexer or count property( yes, array has count property if cast ilist<t> or icollection<t> ). it's greatest possible intersection between both types allows fast access, using for -loops or other supported methods . note methods not supported if can called add , you'll notsuportedexception @ runtime("collection of fixed size") if use array.

i use multiple dimensions in crossfilter (e.g. dimensions date, category, status). works expected, want have id-dimension fast retrieving single data object. problem is: if filter iddimension.filter(myid), , @ same time other filters (which filter out object id=myid) applied, crossfilter won't find given data object. (afterwards reset iddimension.filter(null)). is there way bypass other filters single crossfilter query? or there should method save , restore current filters. doing filter on unique value dimension in order retrieve single record inefficient in crossfilter. remove records except single record groups, add them when remove filter. means group aggregation addition , subtraction functions run twice on each of these records, no reason @ all. it depends on exact need is, think better option keep array of records outside of crossfilter sorted on id property , use crossfilter.bisect find record, or create map of records keyed on unique id (use es6 map if

i added "xunit.net runner visual studio" v0.99.8 via extensions manager, when open test explorer window, not seem pick of unit tests. also, resharper 9 eap version of resharper supports vs2015 seem yet have plugin xunit test runner. how then, can run xunit unit tests in vs2015 preview? you can find answer here: http://blogs.msdn.com/b/webdev/archive/2014/11/12/announcing-asp-net-features-in-visual-studio-2015-preview-and-vs2013-update-4.aspx visual studio supports running , debugging asp.net 5 xunit tests through test explorer. need add xunit dependencies , test commands test project's project.json file, shown below (note: install xunit packages need add https://www.myget.org/f/aspnetvnext/api/v2 nuget package source): "dependencies": { "xunit.krunner": "1.0.0-beta1" }, "commands": { "test": "xunit.krunner" }, if asking how add https://www.myget.org/f/aspnetvnext/api/v2 nuge

what trying asking user enter in format like: cd directory. store "cd" in string , "directory" in string. here code: void main() { char buf[50], cdstr[2], dirstr[50]; printf("enter something: "); fgets(buf, sizeof(buf), stdin); //store cd in cdstr strncpy(cdstr, buf, 2); printf("cdstr: %s(test chars)\n", cdstr); //store directory in dirstr strncpy(dirstr, buf+3, sizeof(buf)-3); printf("dirstr: %s(test chars)\n", dirstr); } the output below input: cd pathname cdstr: cdcd pathname //incorrect answer (test chars) //an "\n" dirstr: pathname //correct answer (test chars) //an "\n" that's why? this because after doing strncpy(cdstr, buf, 2) , don't have null-terminated string in cdstr char array. can fix changing cdstr length 3 , adding: cdstr[2] = '\0' : void main() { char buf[50], cdstr[3], dirstr[50]={0}; printf("

hey i'm trying insert 800 rows @onetomany relationships, seems slow. don't quite understand why, since i've read guides said should quick. hope kind soul tell me if there i've misunderstood , can me increase performance of insertions. the repository: @repository public interface footnoterepository extends crudrepository<footnotesentity, long> { @query("from footnotes number =?1 , footnote_type=?2 order date_start desc,id asc") public list<footnotesentity> findfootnotebynumberandtype(long number, string transportnumber, pageable pageable); } the domainclass: @autowired private entityrepository entityrepository; @autowired private footnoterepository footnoterepository; /** * handles jpa interface * * @param * @return success of operation */ @transactional private boolean insertupdatefootnoteentities(list<footnotesentity> footnotes) { boolean success = true; system.out.println("footnotes: " + footn

i'm wondering how storage template option "deleteonexit" works in cloudify 2.7.1 stable. i'm working on openstack cloud, , in case, option "deleteonexit" in "small_block" storage template set true. using dynamic storage allocation way create (with small_block template), attach, mount , format storage via context storage api. when undeploy application, storage not destroyed. normal behavior? thanks. yes normal behavior, dynamic storage, responsible deleting volume when undeploy. here example of deleting volume when 'shutdown' lifecycle event executed: shutdown { context.storage.unmount(device) context.storage.detachvolume(volumeid) context.storage.deletevolume(volumeid); }

i want make simple settings page, went google's documentation below: http://developer.android.com/guide/topics/ui/settings.html created new android testing project, created preferencescreen xml, , preferencefragment class inside mainactivity class. i want settings screen appear when press settings icon, instead shows 1 unclickable item named settings. i know question basic, tried lot make work no results. any please? if want open settings menu inside action bar, shown below : first, need define menu item inside menu.xml file activity : <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" tools:context=".mainactivity"> <item android:id="@+id/action_settings" android:title="@string/action_settings" android:orderincategory="100" android:showasaction="never" /> </menu> second, need i

i'm having troubles current data model , wondering if suggest better way structure data. nodes labelled 'person' have 5-10 properties each like: name, address, nationality, phone, age... , there no unique property use index. since don't want duplicates, every time create new person use merge instead create. problem doing merge i'm matching 5-10 properties on node slows down queries enormously. so taking out properties in each person node separate nodes labeled address, nationality, phone, age performance of merge query? other possible solutions? thanks in advance! how generating guid/uuid that's unique each person , using id each person? merge on property , use on create set other properties e.g. merge (p:person {id: 'abcd-efgh-...'}) on create set p.name = "mark", p.address = "..." or if not maybe hash or combination of properties key e.g. merge (p:person {id: "name-address-nationality-phone"}) on c

is there single property concerning local machine guaranteed unique on both windows , os x regardless of network attached , accessible java? for instance, mac address returned change when active nic changes (user switches between wired , wireless), hence mac address not meet criterion. a hostname closest meeting these criterion: inetaddress localhost = inetaddress.getlocalhost(); hostname = localhost.gethostname(); though in virtual machine environments vm guest cycled nightly, hostname can change (we have such users).

i wondering 2 things. 1) hashset added duplicate value? believe replaces value? if case, linkedhashset? i'm pretty sure doesn't change order, still replace value? (why it?) 2) if wanted use ordered collection doesn't allow duplicates, replace existing value it's duplicate, re-ordering position? ie. linkedhashset, except duplicate values added replaced , positions updated. there collection might this? or have write own? don't want have write own! 1) adding duplicate set not (it returns false immediately, , contents of set not affected), regardless of particular implementation, hashset, treeset or linkedhashset. 2) check out linkedhashmap, is, probably, closest want. has boolean argument constructor, lets specify whether want use "insertion-order" (false) or "access-order". former same linkedhashset, latter "bump" key if re-insert it, , also if up: map<string, integer> map = new linkedhashmap(10, 0.75, true); m

i have tabs working fine , adding 'active' class when clicked. want have text links within tabs content linking each other. have working can't find way tab active: jsfiddle: http://jsfiddle.net/sarah3585/01vas55s/ so here want apply active class tab2 when link clicked within tab1. html: <div class="tabs"> <div class="selection"> <ul class="tab-links"> <li class="active"><a class="tab-link button" href="#tab1">button1</a></li> <li><a class="tab-link button" href="#tab2">button 2</a></li> </ul> </div> <div class="internal-container tab-content"> <div id="tab1" class="tab active"> tab 1 content <a href="#tab2" class="tab-link">link tab2</a> </div>
