hi have strange behaviour in rails 4. have partial next code: #add_tabs = link_to "add tab", "#", id:"test" #data_retrieved :javascript $("#test").bind("click",function(){ alert("i'm working"); }); and everythime reload page alert fired. i'm lost. thanks in advance. update: thanks pavan realised happened. rails 4.1.8 uses turbolinks manages links on site in order preloaded. therefore everytime site reloads links fired. prevent behaviour must (as pointed pavan) set links remote: true in order let them managed ajax/javascript event. this: link_to "add tab", "#", id:"test", remote: true also, , more important, must use gem 'jquery-turbolinks' and sure application.js looks this: /= require jquery //= require jquery.turbolinks //= require jquery_ujs // // ... other scripts here ... // //= require turbolinks last not least, sure binding callbacks s

i'm using codemirror javascript code coloring, , when put string in quotes "like this" colored fine. but when put string line break "like this" color messed on second line. is there way make sure color starts first quote , ends second quote, if there line break? javascript doesn't allow multi-line strings. can use backslash before newline, or use template literals (backtick-quoted strings), if don't, aren't writing valid javascript, , reason why codemirror mode doesn't highlight code expected.

i need provide single update file customer in order update embedded system via usb. system built using yocto . i'm curious if plan have implement usb updating viable, or if i'm missing should obvious. opkg exists on system, in order use opkg update needs have repo pull from. since have no network capabilities need put entire repo on usb drive. since need provide single file customer repo need tar file. procedure plug usb drive in the udev rule calls script , pushes background since long process (see this ) un-tar repo update file opkg update notify user may remove usb drive at least high-level point of view sound way update embedded system via usb? pitfalls might exist? well, regarding pitfalls might exist, 1 of biggest pitfall power outage in middle of process. how recover in case? (the answer might depend on type of embedded device making). (personally, i'm in favour of complete image based upgrades , not package based upgrades). regarding

i'm facing problem @ work on very big system which, because of server performances , ressources, can't have exceptions managment. instead, system architects have decided return nothing when, exemple, database connector finds nothing. system coded in vb.net. i aware returning , passing nothing bad habbit various reasons such violation of of solid principles, noise in code null checks , addition of fragility because of nullpointerexceptions can passed-by. alongside fact returning nothing can mean hell lot of things (did crash?, did encountered error 1 of dependencies?, parameters valid?...) book "clean code" robert c. martin (or uncle bob) talks saying it's not practice. the question alternatives returning null not old doesn't give alternatives on instead of returning nothing. there's null object pattern . read on subject community seems divided in 2 camps, discourage use saying it's hiding faulty design , says it's actualy solution. i

could explain why code running in infinity loop? why movenext() return true always? var x = new { templist = new list<int> { 1, 3, 6, 9 }.getenumerator() }; while (x.templist.movenext()) { console.writeline("hello world"); } list<t>.getenumerator() returns mutable value type ( list<t>.enumerator ). you're storing value in anonymous type. now, let's have @ does: while (x.templist.movenext()) { // ignore } that's equivalent to: while (true) { var tmp = x.templist; var result = tmp.movenext(); if (!result) { break; } // original loop body } now note we're calling movenext() on - copy of value in anonymous type. can't change value in anonymous type - you've got property can call, give copy of value. if change code to: var x = new { templist = (ienumerable<int>) new list<int> { 1, 3, 6, 9 }.getenumerator() }; ... you'll end getting reference in anon

this question has answer here: when used correctly, htmlspecialchars sufficient protection against xss? 3 answers i know both use prevent xss attack. when use htmlspecialchars , seems ok. <script> , <?php ?> displayed on screen. means not functioning, right? so, question , htmlspecialchars enough preventing xss. if so, reason using strip_tag or white list of tag? htmlspecialchars safe enough. common displays same user typed, makes harmless. strip_tags takes tags away, usefull alot of other things.

this situation: - table user (id, name) - table role (id, name) - link table usersroles (iduser, idrole) in link table iduser , idroles fks , both of them marked composite primary key. in ef produces following models: public class user { public int id {get;set;} public string name {get;set;} public icollection<role> roles {get;set;} } public class role{ public int id {get;set;} public string name {get;set;} public icollection<user> users{get;set;} } when inserting role user strange thing happens. user.roles.add(role); context.savechanges(); creates entry in usersroles table , adds role in role table. practically duplicates role trying associate user. is ef related? because fk , pk settings tables? any hint appreciated. does role adding have id value of role exists. if has name ef may add new entry database.

there other way/trick store depth map in database? basically, trying store 300000 double values. if helps can convert array nsmutablearray or similar can serialize it. don’t know yet how it. tried find way convert binary file instead of ascii no luck yet. you can save lot of memory storing raw binary data in blob. if don't have fixed rows , cols of matrix, can put @ beginning of file 2 integers rows , cols. i'll add simple example on how save , load data of matrix, preceded rows , cols. #include <opencv2/opencv.hpp> #include <fstream> using namespace cv; using namespace std; int main() { mat1d m = (mat1d(3, 3) << 1, 2, 3, 4, 5, 6, 7, 8, 9); mat1d n; { ofstream ofs("test.bin", fstream::binary); ofs.write((char*)&m.rows, sizeof(int)); // save rows ofs.write((char*)&m.cols, sizeof(int)); // save cols ofs.write((char*)m.data, m.total()*sizeof(double)); // save data } {

while trying update fedora release got following error: gpg key retrieval failed: [errno 14] curl#37 - "couldn't open file /etc/pki/rpm-gpg/rpm-gpg-key-fedora-x86_64" therefore update not finish. not able install using yum due same error. i'm running of fedora 21 (recently updated fedora 19 using fedup). i looked @ differens of files fedora-updates.repo , fedora-updates.repo.rpmnew in directory /etc/yum.repos.d/ i notiched $releaseserver varialble missing in fedora-updates.repo so changed lines from gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-fedora-$basearch to gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-fedora-$releasever-$basearch after update without problems.
