i expect replacing tzinfo using 'us/central', give same result using timezone object ( pytz.timezone('us/central') ), apparently it's not: in [5]: import arrow in [6]: d = arrow.get() in [7]: cst = pytz.timezone('us/central') in [8]: d.replace(tzinfo=cst) out[8]: <arrow [2015-07-22t17:40:30.947579-06:00]> in [9]: d.replace(tzinfo='us/central') out[9]: <arrow [2015-07-22t17:40:30.947579-05:00]> note how output of line 8 has different utc offset output of line 9. which way correct way of replacing timezone using arrow , pytz? this seems bug. guessing seeing issue 154 - .to() incompatible pytz.timezone you may seeing same thing .replace() method. issue still open. i use arrow one, seems arrow , pytz not compatible.

i'm experimenting local android tests (the ones run on local jvm, not on device). understand classes in android.jar can't used unless mocked, reason when try instantiate new view (or own class inherited view)- null. totally breaks belief "new" never returns null in java. here's test code ( src/test/java/com/example/footest.java ): package com.example; import android.view.view; import org.junit.test; public class footest { @test public void testview() { view v = new view(null); system.out.println("view = " + v); } } this code prints in test report output view null. here's build.gradle (the rest of project generated android create project , of no interest): buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.3+' } } apply plugin: 'android' android { compilesdkversion 'android-22' buildtoolsversion...

i have class template cfoo<t> . want allow implicit casts other instantiations of cfoo , template argument base class of t . i tried use sfinae, neither of attempts worked on compiler tried (vc 2012 or gcc): #include <type_traits> template <class t> class cfoo { public: template <class q> operator // typename std::enable_if<std::is_base_of<q, t>::value, cfoo<q>&>::type // should work? // typename std::enable_if<1, cfoo<q>&>::type // should work? cfoo<q>& // compiles, doesn't restrict on q want () const { return *(cfoo<q>*)this; } }; class {}; class b : public {}; int main(int argc, char* argv[]) { cfoo<b> b; cfoo<a>& = b; return 0; } why don't either of commented out attempts @ sfinae work here? in both cases error invalid initialization of a , if operator didn't called. according...

evening everyone, i've spent while having play on google learning how create basic form powershell. i'm having problem coming grips how basic form output html file @ click of button have managed work services ie - get-service | convertto-html | out-file "location" however i'm wanting input data on form , once submit button pressed, puts data table , outputs html file. add-type -assemblyname system.drawing add-type -assemblyname system.windows.forms $form = new-object system.windows.forms.form $form.text = "basicform" $form.width = 800 $form.autoscroll = $true #vrn label $objlabel = new-object system.windows.forms.label $objlabel.location = new-object system.drawing.size(50,75) $objlabel.text = "num:" $objlabel.autosize = $true $form.controls.add($objlabel) #vrn textbox $objtextbox = new-object system.windows.forms.textbox $objtextbox.location = new-object system.drawing.size(100,75) $objtextbox.size = new-object system.drawing...
