Does creating a Twilio Capability Token require a request to Twilio's servers? -

does creating twilio capability token require request twilio's servers? if understand correctly, creating twilio capability token involves kind of encryption process happens exclusively on own server. when call library create one, not making call twilio's servers, correct? if purely encryption process, encryption process that's designed "slow". if so, how slow? i believe creation of token according c# api, happens on own server. process creates json web token , returned generatetoken call. cannot see cause above call slow @ all. i know server side code, process blindingly fast, in our production servers, when token expires twilio client, requests new 1 server , initialises again, process takes less 2 seconds complete , client once again able either make or receive calls, depending on allowed capabilities. perhaps if share more experiencing slow, 1 able more? i hope helps.

ruby on rails - Cross-Origin Request Blocked with Ajax after taking site to SSL -

we using ruby 2.1.2 rails 3.2.14. getting following error on browser's console ajax requests after moved our site ssl. cross-origin request blocked: same origin policy disallows reading remote resource @ https://sitename.com/xxx/xx?id=xx. can fixed moving resource same domain or enabling cors. we've tried adding headers: { 'access-control-allow-origin': '*' }, crossdomain: true but no effect. here ajax code : $.ajax({ type: "get", data: {id: id}, url: path+id, headers: { 'access-control-allow-origin': '*' }, crossdomain: true, success: function(data) { } }); any other suggestions?? you have set headers on server side. not on client. simplest way use in applicationcontroller: after_filter :set_access_control_headers def set_access_control_headers headers['access-control-allow-origin'] = '*' end

if statement and visible statement dont work but the things inside it work? ACTIONSCRIPT 3 -

yeah here's code if(defaultmeter.visible = true) { meter1.visible = true; meter1.x = 124.10; meter.y = 63.10; jizz.visible = false; } thing things inside { } work the if statement doesnt apply when defaultmeter not visible, stuff inside {} still applies :c please if mc.visible = true assign true value mc.visible make mc visible true . to compare in level, use == (equal) operator check if 2 values equal or != (not equal, different ) check if 2 values not equal. so in case can : if(defaultmeter.visible == true){ // instructions here } or if(defaultmeter.visible != false){ // instructions here } or simply if(defaultmeter.visible){ // instructions here }

java - Continuous testing with IntelliJ Idea -

i'm looking intellij idea plugin run tests each time change code. looked such solution , found: infinitest , works, inconvenient because need add facet each module, , opens new tool window each module (which means 15 tool windows me). fireworks - didn't work me, maybe doesn't work idea 14 (in its repo can see last changes made in 2009). intellij reports throws exceptions. there lots of ways run tests (including writing simple script this), i'm looking tool smart enough rerun failed tests first, , understand module dependencies (so after change in module run tests of dependent modules). i prefer free options, if there's paid reasonable price, accept well. intellij has toggle auto-test in run dialog. run run-configuration , select toggle auto-test in run dialog. it's not intelligent have hoped. reruns when detects changes.
