i'm building nodewebkit app keeps local directory in sync remote ftp. build initial index when app run first time download index file remote server containing hash files , folders. run through list , find matches in user's local folder. the total size of remote/local folder can on 10gb. can imagine, scanning 10gb worth of individual files can pretty slow, on normal hdd (not ssd). is there way in node efficiently hash of folder without looping through , hashing every individual file inside? way if folder hash differs can choose expensive individual file checking or not (which how once have local index compare against remote one). you iteratively walk directories, stat directory , each file contains, not following links , produce hash. here's example: 'use strict'; // npm install siphash var siphash = require('siphash'); // npm install walk var walk = require('walk'); var key = siphash.string16_to_key('0123456789abcdef');

i'm new c++ hope question isn't dumb, plus i've searched around , couldn't find answer. so brings my question, there difference in loading times between calling std::cout , calling cout when using namespace std added code? imagine if there difference should unnoticeable, i'd sure before turning in project. by way, in university told using namespace std okay (i've read @ lengths on , whether practice or not not in question right now). there no difference. , performance should last of concerns when making these kinds of "micro" code decisions.

i trying create multiple choice quiz. if user selects correct answer shown alert saying "correct" , quiz moves on next question. if user selects incorrect answer shown alert saying "incorrect". want quiz give user 1 last attempt before moving on next question. have tried using variable "tries" keep track of how many times user has attempted question. currently, code proceeds next question if user selects correct answer, if incorrect answer chosen, "incorrect" alert pops , quiz proceeds next question anyway. i have external 2-d array stores questions , respective multiple-choices , solution. renderquestion() takes corresponding choices each question , writes html display question webpage. checkanswer() goes through each choice until finds choice user selected. if it's correct, increments correct counter , if it's incorrect want tell user "incorrect" , quiz give user 1 last attempt on question before proceeding next one.

i have strange problem define set of event listeners inside document.ready or window.load , nothing happens when load page , try trigger 1 of them. i first thought might dom issue, if console.log() each element i'm binding listener to, logged successfully, indicating me it's not problem dom. if bind listeners other elements on page, seem work fine. if copy/paste code below console, works fine. i've tried not wrapping them in document.ready or window.load function, makes no difference. i've tried adjusting location of script. i've placed in head, footer, , in separate file loaded through asset pipeline in rails. again, makes no difference. there no other listeners tied these elements anywhere in code. missing here? $(document).ready(function () { // console.log() statement returns correct dom element console.log($('#direct-apply-btn')); // one: console.log($('[data-toggle="popover-filter"]')); var popov
