i'm creating framework execute processes @ specific time (cron-like) , test i'm using chai-mocha-grunt. the architecture of solution based on this example . basically, have: a master process, calls child (via child_process.fork) specific number of times. a child process, executes using setinverval(); a process call master.start() function. with architecture how test ensure threads executed @ correct time using mocha , chai (with 'assert' library)? in other words, how make chai 'listen' threads , check if executed @ correct time? i'm not sure need chai listen threads. if you're building off of example linked should pretty straight forward because master.js eventemitter , it's emitting events hears child processes. your test structure simple this: describe('forkexample test', function() { // set appropriate test timeout here this.timeout(1000); it('should stuff @ right time', function(done) {

i noticed other day 1 of web pages looking ugly. buttons on page looked totally different , based on whether contained 1 line of text or two. after digging, i've learned typical button uses nsroundedbezelstyle , has fixed height. so, if text going wrap, firefox (and chrome , safari) change button use nsshadowlesssquarebezelstyle can have variable height. i'd petition maintainers of these browsers change , researching best alternative. after finding already-filed bug , doing reading, suggested maybe use nstexturedsquarebezelstyle instead. turns out in mavericks looks same nsroundedbezelstyle button. same in yosemite, except has no border. changing setbordered has no effect. so question, on behalf of browser developers everywhere: is possible draw nstexturedsquarebezelstyle button border ? or, there way around browser vendors have missed? rewritten answer i'm not seeing nstexturedsquarebezelstyle button showing borderless in yosemite: this stoc
