there lot of topics when synchronization in java appears. in many of them recommended using invokation of collections.synchronized{collecation, list, map, set, sortedmap, sortedset} instead of collection, list, etc. in case of multithreading work thread-safe access. lets imagine situation when threads exist , of them need access collection via methods have synchronized block in bodies. so then, necessary use: collection collection = collections.synchronizedcollection(new arraylist<t>()); or only collection collection = new arraylist<string>(); need to? maybe can show me example when second attempt instead of first cause evidently incorrect behaviour? to contrary, collections.synchronizedcollection() not sufficient because many operations (like iterating, check add, etc.) need additional, explicit synchronization. if every access collection done through synchronized methods, wrapping collection again syncronized proxy useless.

i need ccrendertexture (white rect) render sprite here (1st picture), render @ lower-left corner (2nd picture). how can change value? first picture second picture rendertextrure.position = ccp(p.x, p.y); rendertexture.sprite.position = ccp(p.x, p.y); rendertexture.sprite.anchorpoint = ccp(0.5, 0.5); edit ccrendertexture initial position ccrendertexture size , position in cocos2d-iphone i found these answers, didn't help. possible change position or not? check if helps you. note uiimage optional incase want use uiimage. ccrendertexture *renderer = [ccrendertexture rendertexturewithwidth:tx height:ty pixelformat:kcctexture2dpixelformat_rgba8888 depthstencilformat:gl_depth24_stencil8]; [renderer beginwithclear:0 g:0 b:0 a:0 depth:1.0f]; [1st_pic_sprite visit]; [renderer end]; uiimage *img = [renderer getuiimage];

from model, how access username of user being edited in cakephp 2.4? i'm using miles johnson's excellent file uploader userpics in cake 2.4 app, using callback in behavior's actsas config determine name file saved under: 'namecallback' => 'getusername', which calls following function: public function getusername() { return cakesession::read("auth.user.username"); } this works great when it's user editing own picture, comes apart when it's admin editing user: callback returns admin's username, not user's. the file uploader uploads file , saves under filename , location specified actsas config: in case, i'm having save images under /webroot/img/uploads , using getusername() function username filename. uploader saves file's url in user model under field image . you can use authcomponent::user('usernane') value if user. http://book.cakephp.org/2.0/en/core-libraries/components/authen...

i'm trying write right linear context free grammar , in difference between numbers of 0's , 1's should even. example: 010001 = 4 - 2 = 2 (even) i had similar problem . maybe help! i'm trying write on prolog. did other 10 exercises difficult me. ideas on how it? my code s --> []. s --> [1],a. s --> [0],b. --> [1],s. --> [0],c. b --> [1],c. b --> [0],s. c --> []. c --> [1],b. c --> [0],a. it's work many cases i'm not sure if well. the problem can simplified little math. let a number of 0, b - number of 1, n - length of word. want abs(a - b) even. do math: a + b = n b = n - a - b = - n + = 2*a - n 2*a even, abs(a - b) iff n even. so task check if length of word even. solution: s --> []. s --> digit, digit, s. digit --> [0]. digit --> [1].

i'm trying design class represent card i've decided use enums represent rank , suit. however, need able take input user and, unfortunately, it's not possible take enum directly cin. for reason, intending take in string , use std::map map each string enum value represents (as described in this question ). didn't want input case sensitive created regex should shift characters lowercase before matching. the code came here: istream& operator>>(istream& is, card& d) { std::map<std::string,card::rank> mr; std::map<std::string,card::suit> ms; mr[std::regex("/two/i")] = card::two; mr[std::regex("/three/i")] = card::three; mr[std::regex("/two/i")] = card::four; mr[std::regex("/two/i")] = card::five; mr[std::regex("/two/i")] = card::six; mr[std::regex("/two/i")] = card::seven; mr[std::regex("/two/i")] = card::eight; mr[std::regex("/two/i")] = card::nine; mr[std...

i know it's been asked many times , i've gone through 15 - 20 questions trying figure out how work. json {"menu": { "title":"title one", "link":"link one", "title":"title two", "link":"link two"} } php $string = file_get_contents("test.json"); $json_a = json_decode($string,true); foreach($json_a['menu'] $key => $value) { echo $key . ": " . $value . "<br />"; } this far displays title: title 2 link: link 2 as opposed to title: title 1 link: link 1 title: title 2 link: link 2 also correct in thinking $json_a[menu] not need apostrophes because $json_a not function? works or without. thanks in advance. you can't have multiple entries same key in array. while json might allow it, when it's parsed php, last definition of key,value pair wins. it looks menu should array of objects instea...
