i working monthly climate data , want dates data covers in form of yyyy-mm such 2015-01, 2015-02, etc. attribute of dataset says 'hours since 1800-1-1 00:00:00'. data covers period 1948-2015 @ monthly resolution. i tried following both not giving me expect: months<-as.posixlt(time_slp, origin='1800-1-1 00:00:00') months<-as.date(time_slp, origin ="1800-1-1 00:00:00") sample time_slp : time_slp <- c(1569072, 1569816, 1570488, 1571232, 1571952, 1572696, 1573416, 1574160, 1574904, 1575624) you can try: as.posixct("1800-01-01 00:00:00")+as.difftime(time_slp, units="hours") to know month of each date, use months : months(as.posixct("1800-01-01 00:00:00")+as.difftime(time_slp, units="hours")) to have in format asked in comments, try strftime (say x object obtained first line): strftime(x,format="%y-%m")

i'm using async library asynchronous programming on nodejs. want make helper method (that use async method), rather put code in same place. here sample code: var solve = function() { async.waterfall([ // long working task. huh function (callback) { settimeout(function() { console.log('hello world!'); callback(); }, 2000); }, function (callback) { authorservice.helperasync(); }, function (callback) { settimeout(function() { console.log('bye bye!'); }, 2000); } ]); }; solve(); in other file, make async function: var helperasync = function() { async.waterfall([ function(callback) { console.log('task 1'); callback(); }, function (callback) { console.log('task 2'); callback(); } ]); } i want result should be: hello w

i have php/laravel best practice question. here scenario: have object "type" property in it. type property set integer of kind. depending on "type" integer in object, different actions have happen. what best way process object? trying desperately think of way avoids using whole bunch of if/else statements feels wrong , ugly way approach this. i.e. don't want this: if($obj->type == 1) { //process actions type 1 } else if($obj->type == 2){ //process actions type 2 } would appreciate advice. thanks! thanks @ryan vincent found resource ( https://sourcemaking.com/design_patterns/strategy/php ) , changed strategy design pattern bit. avoiding hard-coded type values check how dynamic class loading done in strategycontext::__construct method. new class instance initiated $type variable name. class names should strings in php way forces types strings not numbers. different original example in article, attached strategycontext

i developing customized setup wizard in android 5.0+. after google login, call google's restore activity following codes, restore activity shows "dark" theme, not "light" other google page. did miss something? intent intent = new intent(); intent.setaction("com.google.android.setupwizard.restore"); bundle options = new bundle(); options.putboolean("useimmersivemode", true); options.putboolean("setupwizard", true); options.putstring("theme", "material_light"); intent.putextras(options); startactivityforresult(intent, restore_code); you can use cyanogenmod's method of adding: options.putstring("scripturi", "android.resource://com.google.android.setupwizard/xml/wizard_script"); it works, activity crashes when going next screen, there's way around it, haven't looked it.
