i have application pretty modular , such, jshint giving me 'x' defined never used error. my setup goes this: app/assets/scripts/bootstrap.js: var x = 5; app/assets/scripts/kickstart.js: console.log(x); and here's output jshint: app/assets/scripts/bootstrap.js line 1 col 6 'x' defined never used. app/assets/scripts/kickstart.js line 1 col 13 'x' not defined. 2 problems i know /* exported x */ cumbersome if have lots of variables this. is there anyway solve these 2 issues without disabling specific options? because come in handy in other, more important, situations. you can add @ top of file. /*jshint unused: false, undef:false */ notice options can applied specific scopes. works unused , apparently not undef .

i have small program needs print numbers in following format: 0 1 2 3 4 3 2 1 0 which try accomplish c code: int main() { int i; (i = 0; < 5 && !fork(); i++) { printf("%d ", i); } wait(null); return 0; } but prints 0 1 2 3 4 0 1 2 3 0 1 2 0 1 0 and can't figure out how omit digits. can see what's wrong? each iteration fork s new child. parent exits loop , wait s child, , child prints iteration number. however, because there no newline, characters remain buffered. however, each fork duplicates buffer in current state. so, each child inherits of printed values ancestors, , waits child die before exiting. so, last child exits, buffers this: parent: "" child-0 : "0 " child-1 : "0 1 " child-2 : "0 1 2 " child-3 : "0 1 2 3 " child-4 : "0 1 2 3 4 " child-4 exits (because wait not block), causing stdout buffer flushed. causes child-3

i want upload following project heroku: https://github.com/eranbetzalel/tick-logger . you've noticed doesn't contain "heroku files" (procfile, different configs, etc...). i want create following configuration local repository: heroku branch - contain "heroku files". master branch - contain source code (no heroku stuff). my plan regularly push local heroku branch heroku remote repository (to master branch) , push local master branch github remote repository (to master branch). does make sense? any suggestion better practices highly welcome. this isn't idea. it's best explicit project -- means making easier other developers figure out how stuff works. with heroku, don't need add project, dependency file, , procfile (usually). i'd vote in favor of including files directly @ top-level avoid future confusion. i can't see benefit of keeping them separate.

is there way detect change of time in getcurrenttime() of youtube api ? purpose:to play single video limited time(<1 min) in page , move on next video. i thinking use object.watch works variables not functions. i try bind in original source code https://s.ytimg.com/yts/jsbin/www-widgetapi-vfl9twtxr.js complicated. because youtube player wrapped in iframe, dependent on player exposes, , while they've exposed current time via getcurrenttime() function, haven't exposed events raised whenever time might updated (in fact, time updated exposed function 6 or 7 times per second, , isn't consistent). so option set javascript timer. lots of ways that; simple 1 this: setinterval(function(){ // here you'd raise sort of event based on value of getcurrenttime(); },100); // polling 8 times second, make sure every time changes. as postmessage iframe isn't consistent, have interval timer greater. or use requestanimationframe poll 60 times second.
