i'm trying write code reliably show div between times. i'm using moment.js , claim in docs can can't find proper way query times need. my code give idea of want doesn't work because when try turn on or off feature, if time goes before midnight, end negative numbers instead of time. (i using utc times , subtracting 10 hours. can use negative numbers in arrays clarity, i'd stick actual times as possible.) also, way code now, can turn off feature @ time turning off after time better, having on between times best. would guys know how query moment( ).isafter or .isbetween time rather dates? so far i've tried many permutations of: moment().isbetween('7:00:00', '8:00:00', 'hour', 'minute'); , .isafter. the docs don't seem have examples , no 1 on web has posed question in past. thanks! var opensun = [6,7,17,22]; // on hours // sundays ---------------------------------------------- // // setup sunday - on if (mome

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.

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 run query returns 2 rows select table-a condition=something; row1 value1 row2 value2 now, want put in new table in 2 columns of single row select column1, column2 table-b condition=something; row1 column1 column2 value1 value2 can please me this? it unclear how want pick row goes column - here couple of options: select min( ) minimum_value, max( ) maximum_value table_a 1=1; or select max( ) keep ( dense_rank first order rownum ) first_value, max( ) keep ( dense_rank last order rownum ) last_value table_a 1=1; or select * ( select a, rownum rn table_a 1=1 ) pivot ( max(a) rn in ( 1 first_value, 2 second_value ) );

in few different places call: $model=new makecall($form); i have updated makecall class several changes want take affect after given date. renamed original class makecallold how can leave calls to: $model=new makecall($form); intact , within makecall this: class makecall { ... public function __construct($form) { //use legacy makecallold stuff before 2016-10-01 if ($form['date']<'2016-10-01') { $object=new makecallold($form); return $object; } $this->perform several functions , set variables... this returns empty object of class makecallold not appear run constructor in makecallold properties empty. entire object of makecallold dropped $model . what need static factory constructor. way should doing add initialization logic or switch constructors depending on argument. class makecall { public function __construct($form) { $this->form = $form;

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
