i'm coding cache server in ruby , need make expiration times data i'm storing. when user stores data under key foo example sets expiration time in seconds. data needs deleted @ moment thought scheduling create thread , put sleep until time comes. thread.new(@options[:exp_time], key) |t, k| exp = time.now + t sleep(t) if @data.key?(k) && @data[k][:exp_time] <= exp #check if hasn't been updated @data.delete(k) end end t time user sent , key key under data stored. expiration time changed if user replaces data stored @ key check it. wondering if use of threads or if consumes resources or there's easier way. can't use gems or libraries of type. in advance help that's going create crazy number of threads in short time if put under load. want priority queue elements sorted expiration time , periodic timer checks if first entry expired, processes it, , repeats until there's nothing left expire, goes sleep briefly....

i've noticed rem unit can usable element's sizes, not font-sizes. , usefull html font-size property. html { font-size:1vw } @media , (max-width:720px) { html { font-size:10px } } #el { width:20rem;height:5rem } but proper , trustable? i think thats you. i apply: rem font-sizes px callback, best ! em paddings , margins px, %, vw , vh element sizes and media queries use em, rem , px used too. you can mess children element if use em font-size, not recommended. rem size elements interesting, i'm enjoying lot vw , vh responsive behaviors cases % not enough. and can cool stuff css calc function like width: calc(100% - 85px); fixed size within design. this recommended read units :) hope you.

i looking @ documentation datepickerios component , use getdefaultprops() initialize props in component. getdefaultprops: function () { return { date: new date(), timezoneoffsetinhours: (-1) * (new date()).gettimezoneoffset() / 60, }; }, getinitialstate: function() { return { date: this.props.date, timezoneoffsetinhours: this.props.timezoneoffsetinhours, }; }, what equivalent of using es6 syntax? because have been using: constructor(props) { super(props); this.state = { //equivalent getinitialstate here }; } should this.props = { } set default props? see this: https://github.com/facebook/react/issues/3725 class x extends react.component { } x.defaultprops = {...} if using babel-plugin-transform-class-properties package, can this: class x extends react.component { static defaultprops = {...} }

i have 12-hd-monitor setup, using 2 radeon firepro w600 graphic cards (2gb ram each), running windows 10 os, 16gb ram, , brand new i7-6th gen. cpu. i'm trying write program runs 4 videos across monitors (each video stretched on 3 monitors), yet no matter component use (mediaplayer, vlc.net...) when 3rd video loaded videos start skipping frames. the cpu , memory stats indicate there's no problem system's resources, peaks 20-30%. what's best way play multiple videos simultaneously (smoothly) on 12-monitor system, described, using c#? as turns out, problem lack of vram. 2gb vram each video card, computer can run 2-3 fullhd (1920x1080) monitors smoothly. there's no way force computer use system's memory rendering monitors, our system's bottleneck. by decreasing monitors' resolution, able run more videos, more smoothly, simultaneously on 12 monitors.
