i ssl request through load balancer performing ssl termination , sending decrypted traffic server on port 81. i'm running nginx , have setup listener port 81 , tell rails app ssl request. here how nginx config looks like: server { listen 81; server_name server; root /var/www/app/current/public; error_log /var/log/nginx/app-error.log; access_log /var/log/nginx/app-access.log; passenger_enabled on; client_max_body_size 100m; location / { passenger_enabled on; proxy_set_header x-forwarded-proto https; } } it goes through ruby on rails doesn't detect header request.headers['x-forwarded-proto'], takes request non-https. should add in order rails thinking ssl request? so proxy_set_header not used passenger, need use passenger_set_cgi_param instead: passenger_set_cgi_param http_x_forwarded_proto https;

i'm trying stream data server @ regular intervals , in way fast , not block ui. ui pretty busy trying display data. implementation uses nstimer fires every 50ms, picks network packet out of circular array , sends over: //this timer networkwritetimer = [nstimer scheduledtimerwithtimeinterval:0.05 target:self selector:@selector(sendactivity:) userinfo:nil repeats:yes]; -(void)sendactivityinbackground:(id)sender { [[appconfig getinstance].activeremoteroom.connection sendnetworkpacket:[circulararray objectatindex:arrayindex%arraycapacity]]; } -(void)sendactivity:(nstimer*)timer { // send out [self performselectorinbackground:@selector(sendactivityinbackground:) withobject:nil]; } i'm not satisfied performance of method. time profiling has revealed there's overhead associated performing background selectors, , performance can quite choppy. i'm thinking of additional ways improve performance: improve p...

this question has answer here: parallel algorithms generating prime numbers (possibly using hadoop's map reduce) 1 answer does have idea what's approach parallel prime factorization algorithm ? i can't figure out @ stage of algorithm should divide threads .. how can think prime factorization in parallel way ? consider following 1 thread code: public static void primefactorization(arraylist<integer> factors, int num){ //factors array save factorization elements //num number factorized int limit = num/2+1; if(isprime(num)) factors.add(num); else{ while(num%2==0){ factors.add(2); num=num/2; } (int i=3; i<limit; i+=2){ while (isprime(i) && num%i==0){ factors.add(i); ...

i've drawn graph using data out of database, , want line turn red when number in database gets higher 500 (like below). unfortunately doesn't work way, , i've tried other stuff, no succes. though dashed line work using code .style("stroke-dasharray", ("3, 3")) my question: possible let stroke color turn red when y value gets higher point in d3.js? // adds svg canvas var svg = d3.select("body") // explicitly state svg element go on web page (the 'body') .append("svg") // append 'svg' html 'body' of web page .attr("width", width + margin.left + margin.right) // set 'width' of svg element .attr("height", height + margin.top + margin.bottom)// set 'height' of svg element .append("g") // append 'g' html 'body...
