i have written code calculate effects using delta method in r i have dataframe dpcp variables x1 , x2 , x3 , x4 , matrix of 1000 draws multivariate normal, m4[1000,4] . this code calculates effects, takes long run. how can run faster: n = nrow(dpcp) (i in 1: n) { (j in 1: 1000) { marg_effects[i, j] = (m4[j, 1] * dpcp[i, ] $x1) + (m4[j, 2] * dpcp[i, ] $x2)+ (m4[j, 3] * dpcp[i, ] $x3) + (m4[j, 4] * dpcp[i, ] $x4) } } the code takes upwards of 5 hours 2000 observations. you may want check this out first. however, speed computation, use matrix multiplication instead of looping marg_effects <- as.matrix(dpcp) %*% t(m4) the %*% operator matrix multiplication , t() function transpose m4 hope helps.

working on loop receives messages , processes them accordingly, websocket echo-er keep-alives , authentication, , i've been stuck in keep-alive part little while now. the concept simple, when server starts create goroutine ticker, , initialize uint64 pointer, each time ticker ticks (every 2 seconds), increment pointer atomic.adduint64(clockticks, 1), each websocket connection goroutine, check variable every tick compare , atomic.loaduint64(clockticks), , send ping/pong message. edit: seems blocking loop until message received, result: i := atomic.loaduint64(clockticks) if != cur { cur = if act != true { fmt.println("quit nao u filthy bot.") return } else { fmt.println("keep going.") act = false } } in snippet, := atomic.loaduint64(clockticks) & if block runs when message sent (prints "keep going." on msg), not want, want snippet run every iteration, ...

so learned bit hidden class concept in v8. said should declare properties in constructor (if using prototype based "pseudo classes") , should not delete them or add new ones outside of constructor. far, good. 1) properties know type (that shouldn't change) not (initial) value ? for example, sufficient this: var foo = function () { this.mystring; this.mynumber; } ... , assign concrete values later on, or better assign "bogus" value upfront, this: var foo = function () { this.mystring = ""; this.mynumber = 0; } 2) thing objects. know object wont have fixed structure, want use hash map. there (non verbose) way tell compiler want use way, isn't optimized (and deopted later on)? update thanks input! after reading comments (and more on internet) consider these points "best practices": do define all properties of class in constructor (also applies defining simple objects) you have assign something the...

i m using full calendar web app project , sync google calendar of client, moment public calendar. is there way sync private calendar ? note : use 0auth identify , sync google account. thanks i think work private calendar using correct authorization. authorizing requests oauth 2.0 all requests google calendar api must authorized authenticated user. here sample create alexandre : <script type="text/javascript"> var clientid = '<your-client-id>'; var apikey = '<your-api-key>'; var scopes = 'https://www.googleapis.com/auth/calendar'; function handleclientload() { gapi.client.setapikey(apikey); window.settimeout(checkauth,1); } function checkauth() { gapi.auth.authorize({client_id: clientid, scope: scopes, immediate: true}, handleauthresult); } function handleaut...

i have process a. has various scripts s1, s2, s3, s4, s5. previously process merely calls script functions. s1->tick(currenttime). however, standardize sandboxing of these scripts , move them external processes. my question is: what best portable c++ (linux/osx/win32) method signal subprocesses new tick dataset available. what best portable c++ way make data available. for instance, perhaps write data shared memory area (writable primary process) , have sub processes read memory area? would faster having sort inter process communication?

this method within factory: kbuser.getcurrentuserdetails = function(){ return $rootscope.ref.child("user/" + firebase.auth().currentuser.uid).once('value', function(snap){ return snap.val(); }); } i call method in controller this: return kbuser.getcurrentuserdetails().then(function(details){ // here need .val() once again (var attrname in details.val()) { kbuser.userobject.details[attrname] = details.val()[attrname]; } kbuser.copyfirebasedatatouser(firebaseuser).then(function(){ return true; }); }); this returned: details = w {a: p, w: u, g: ve} , doesn't correspond database. when read details variable here, have details.val() again expected json object database. don't why result of snap.val() isn't returned in method, 'raw' firebase datasnapshot snap . know why occurs? assume factory setup correctly. basically need use chain promise when snap.val() gets return can data in it. ...

i have been experimenting nifi (via hortonworks hdf) , can't grasp seems basic. start file..i want filter records based on value (e.g., field number 2 contains "xyz")...then write matching records hdfs. i have non-filtered flow working can't find docs or examples showing how apply schema (or in way understand "content") of file. what missing? (i have seen references flowfiles being "schema-less" - not sure how useful). for example, file this: [app1][field1][field2] [app2][field1][field2] [app2][field1][field2][field3] [app3][field1] i want filter select records containing "[app2]" , create hdfs file looks this: field1,field2 field1,field2,field3
