i've started learning react , i'm trying build simple audio player. i'm using example reference it's built in 1 file https://github.com/cezarluiz0/react-cl-audio-player the 1 i'm trying make done in "react" way ui has reusable components i'm having trouble separating code meaningful , working components. example, if try move of rendering code parent component (audioplayer) (playbutton), audio methods created on mounting of parent component becomes inaccessible child components. here code repo. https://github.com/vincentchin/reactmusicplayer it works i'd improve it. it'd great if can point out huge flaws in since i'm sure i've broken rules or standards coding in react. you can access parent component's methods child component passing method prop, , invoking inside child component. for example (in child component's render method): <button onclick={this.props.methodfromtheparent}>click me</button

is possible run interactive shell inside tclsh? it's easy run interactive shell such bash or tclsh inside bash, have not found way reverse. if run "exec tclsh" or "exec bash" inside tclsh don't prompt until type "exit" , hit enter, or use "ctrl-c" kills parent tclsh. i prefer not use external package, if @ possible. provided don't want pass values (other exit code) back calling tcl code can pretty redirecting standard channels tcl doesn't capture them: exec tclsh <@stdin >@stdout 2>@stderr this work pretty subprocess (i've tested vi ) , tclsh magically in interactive mode if decides try running subprocess. if want more complex that, need using expect there's long list of tricky gotchas otherwise.

i have rails (3.2) app runs on nginx , unicorn on cloud platform. "box" running on ubuntu 12.04. when system load @ 70% or above, nginx abruptly (and seemingly randomly) starts throwing 502 bad gateway errors ; when load less there's nothing it. have experimented various number of cores (4, 6, 10 - can "change hardware" it's on cloud platform), , situation same. (cpu load similar system load, userland 55%, rest being system , stolen, plenty of free memory, no swapping.) 502's come in batches not always. (i run 1 unicorn worker per core, , 1 or 2 nginx workers. see relevant parts of configs below when running on 10 cores.) i don't know how track cause of these errors. suspect may have unicorn workers not being able serve (in time?) looks odd because not seem saturate cpu , see no reason why wait io (but don't know how make sure of either). can you, please, me how go finding cause? unicorn config ( unicorn.rb ): worker_proces
