does code have defined behaviour in c++ standard library? std::forward_list<t> list; list.erase_after(list.before_begin()); intuition no, haven't been able locate exact standards wording particular case. the precondition on erase_after is: iterator erase_after(const_iterator position); requires: iterator following position dereferenceable. so example has undefined behaviour, because list empty, list.before_begin() not incrementable, there no iterator following it. if list has @ least 1 element list.erase_after(list.before_begin()) valid.

i've encountered situation can't understand. i've created patch db, drops constraints(private keys) , drops indexes bound constraints. worked flawlessly few times on test environment. when run on prod crashed on first index. test db re-created test production few times(but don't know how done exactly) , there wasn't problems. how possible error didn't occurred while testing? it possible dropping constraint drops supporting index, depending on how constraint , index created in first place, script ought check that. it more robust create non-unique indexes , add primary , unique constraints use indexes, can drop constraint without losing benefits of having index in place. the difference in behaviour when dropping constraints based on existing or system-generated index documented here: http://docs.oracle.com/database/121/sqlrf/clauses002.htm#cjagebig

i saw few blog articles saying angularjs , jquery used in 1 app. seems jquery has functionalities angular doesn't have , angular allows make structured logic web app. the fact is, i'm french take @ french blog articles that, , french tends should never use jquery , angular together. asked why on forum , people said it's because beginners use jquery , angular same things : adding elements dynamically, use ajax requests, etc... i'd use jquery things angular not , allow bootstrap js work on app. what think, jquery , angular bad @ working in 1 single app? or depend on how make them work together? angularjs uses jquery itself, major reason not mix , match described of them stepping on each other's toes. while learning angular lot of time end using jquery alongside because didn't understand angular or know it's full capabilities. after learning better code has continuously less jquery in it, if can't figure out in angular, i'll make sure

i have setup edittext box , set maxlength 10. when copy edittext string mytitles. need mytiles 10 chars long , not dependent on entered in edittext box. mytitles[0] = titlesedit.gettext().tostring(); the edittext filled abcd need add 6 spaces or placeholders after abcd. have seen other post str_pad , substr without success mytitles[0] = str_pad(strtest, 0, 10); mytitles[0] = substr(strtest,0, 10); try like public static string newstring(string str) { (int = str.length(); <= 10; i++) str += "*"; return str; } this return string * replaced empty ones. so, eg, if string abcde , on calling newstring() below mytitles[0] = newstring("abcde"); will return abcde***** output.

i using three.js collada loader import .dae file texture (.png) image applied. need overwrite .png file new texture, , creating texture using canvas element exports .png format. if clear cache, change texture (i naming exported "new" .png texture same filename original .png texture referenced in .dae file). how can ensure new texture recognized/rendered without having user clear cache? example: user creates new texture, , exported on original texture, , collada file re-renders after user clicks button render box. once have javascript image object in memory, regardless of source, can assign objects' materials' textures via .image attribute. you'll need let thre.js know alter binding. example, if have new image called, say, img , mesh called mesh typical material: mesh.material.map.image = img; mesh.material.map.needsupdate = true; should trick. no need send dom elemetn disk .png, use it.

a infinitely long stream of 0's , 1's coming ,you have find out whether number formed far divisible 3 or not. i tried finding decimal equivalent of binary number , summing digits , finding if sum divisible 3 or not. know wrong method because number infinitely long after time number out of range. approach this. another approach find out positions set bits , odd positions set bits , if difference of total number of set bits odd , positions divisible 3 number divisible 3. here after sum time number out of range. is there better approach? just keep track of x = current number mod 3. if b next bit, update: x = (2*x + b) % 3 when x = 0 current number divisible 3
