whilst learning develop servlets added c:\program files\apache\tomcat8\lib\servlet-api.jar j2ee project's build path servlets work. fine: i decided instead add entire folder c:\program files\apache\tomcat8\lib "external class folder" , i'm "javax.servlet cannot resolved". this seems make no sense when compared how eclipse adds tomcat library - looks identical: [ i guess questions are: what wrong including entire folder "library"? how 1 add folder appears proper library in "apache tomcat v8.0" library eclipse adds via wizard class-folders folders compiled classes not folder libs. use user-library feature of eclipse in generell have add every jar hand.

i have scoured web days. understand if redirect ($state.go, etc) in resolve, transition cancelled , resolves run again. but, if need prevent going child state. , fetch data in resolves don't need, nor want, fetch again. i can't believe unusual scenario people. if has idea, please me plnkr working! http://plnkr.co/edit/gfdcrqopxkbd1zzwylo9?p=preview var app = angular.module('plunker', ['ui.router']); app.config(['$stateprovider', function($stateprovider){ $stateprovider .state('posts', { url: "/posts", templateurl: "posts-index.html", controller: "postsindexcontroller", resolve: { posts: function(post) { console.log('hi'); return post.all() } }, onenter: function($state, posts) { if (posts.length > 1 && confirm("redirect first post?")) { console.log('howdy') // $st...

given evernote don't publish exact api rate limits (at least can't find them), i'd ask guidance on it's usage. i'm creating application sync user's notes , store them locally. i'm using getfilteredsyncchunk this. i'd know how can make api call without hitting limits. understand limits on per-user basis, acceptable call every 5 minutes latest notes? tia the rate limit on per api key basis. you'll okay calling getfilteredsyncchunk every 5 minutes, although it's little more efficient call getsyncstate instead. in case haven't seen yet, check out this guide info on sync (accessible this page ).

i'm building custom post types wordpress project, not understand why in examples on internet it's possbile find this: register_post_type('omb_prodotti', array( 'labels' => array( 'name' => __( 'customposttype' ), 'singular_name' => __( 'customposttype' ) ) what "__(" used for? related translations? wouldn't possible write instead: register_post_type('omb_prodotti', array( 'labels' => array( 'name' => 'customposttype', 'singular_name' => 'customposttype' ) sorry i'm beginner in both php , building custom wp themes. thank much. it's impossible search __ in search engine wordpress double underscore found answer in wordpress documentation: description retrieves translated string translate(). usage <?php $translated_text = __( $text, $d...

i have 2 dimensional numpy array , using python 3.5. starting learn boolean indexing way cool. can 2 dimensional array, arr. mask = arr > 127 arr[mask] = 0 this works perfect trying change logic use boolean indexing for x in range(arr.shape[0]): y in range(arr.shape[1]): if arr[x,y] < -10: arr[x,y] = 0 elif arr[x,y] < 15: arr[x,y] = arr[x,y] + 5 else: arr[x,y] = 30 i tried multiple conditional operators indexing following error: valueerror: boolean index array should have 1 dimension boolean index array should have 1 dimension . i tried multiple versions try work. here 1 try produced valueerror. arr_temp = arr.copy() mask = arry_temp < -10 mask2 = arry_temp < 15 mask3 = mask ^ mask3 arr[mask] = 0 arr[mask3] = arry[mask3] + 5 arry[~mask2] = 30 i received error on mask3. new know code above not efficient trying work out it. any tips appreciated.

i'm trying random numbers between 0 , 100. want them unique, not repeated in sequence. example if got 5 numbers, should 82,12,53,64,32 , not 82,12,53,12,32 used this, generates same numbers in sequence. random rand = new random(); selected = rand.nextint(100); add each number in range sequentially in list structure. shuffle it. take first 'n'. here simple implementation. print 3 unique random numbers range 1-10. import java.util.arraylist; import java.util.collections; public class uniquerandomnumbers { public static void main(string[] args) { arraylist<integer> list = new arraylist<integer>(); (int i=1; i<11; i++) { list.add(new integer(i)); } collections.shuffle(list); (int i=0; i<3; i++) { system.out.println(list.get(i)); } } } the first part of fix original approach, mark byers pointed out in answer deleted, use single random instance. th...

i have class a defines implicit conversion b . case class a(number:int) case class b(number:int, tag:string) implicit def atob(a:a) = b(a.number,"hello world") i have function retrieves a , invoke function takes argument implicit b : def hello()(implicit b:b)= {....} def execute = { implicit val a:a = .... hello() //doesnt compile missing implicit parameter b } how can code work without explicitly defining b ? i.e val b:b = define function this: implicit def implicitbfroma(implicit a: a): b = and either have in scope when call hello , or put companion object of b . this function not implicit conversion. states, there implicit value of type b available, if there implicit value of type a available in scope. note work, should either defined after atob in file, or atob should have explicitly specified return type: implicit def atob(a:a): b = b(a.number, "hello world") , or should explicitly call atob in body: implicit d...
