To switch between time zones, you need datetime objects that are timezone-aware. from datetime import datetime from dateutil import tz utc = tz.tzutc() local = tz.tzlocal() utc_now = datetime.utcnow() utc_now # Not timezone-aware. utc_now = utc_now.replace(tzinfo=utc) utc_now # Timezon...

int[] arr = new int[] {1, 6, 3, 3, 9}; for (int i = 0; i < arr.Length; i++) { Console.WriteLine(arr[i]); } using foreach: foreach (int element in arr) { Console.WriteLine(element); } using unsafe access with pointers https://msdn.microsoft.com/en-ca/library/y31yhkeb.asp...

Since PHP objects don't inherit from any base class (including stdClass), there is no support for type hinting a generic object type. For example, the below will not work. <?php function doSomething(object $obj) { return $obj; } class ClassOne {} class ClassTwo {} $classOne= new...

const readline = require('readline'); const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); rl.question('What is your name?', (name) => { console.log(`Hello ${name}!`); rl.close(); });

Install Atom for your distribution here. After that run the following commands from a terminal: apm install parinfer apm install language-clojure apm install proto-repl

Objects will often depend on other objects. Instead of creating the dependency in the constructor, the dependency should be passed into the constructor as a parameter. This ensures there is not tight coupling between the objects, and enables changing the dependency upon class instantiation. This has...

To remove an existing alias, use: unalias {alias_name} Example: # create an alias $ alias now='date' # preview the alias $ now Thu Jul 21 17:11:25 CEST 2016 # remove the alias $ unalias now # test if removed $ now -bash: now: command not found

There are multiple threads in your code and you need to safely communicate between them. You can use a Queue from the queue library. from queue import Queue from threading import Thread # create a data producer def producer(output_queue): while True: data = data_computation() ...

In Objective-C, method swizzling is the process of changing the implementation of an existing selector. This is possible due to the way Selectors are mapped on a dispatch table, or a table of pointers to functions or methods. Pure Swift methods are not dynamically dispatched by the Objective-C run...

Putting a & (ampersand) in front of an argument will pass it as the method's block. Objects will be converted to a Proc using the to_proc method. class Greeter def to_proc Proc.new do |item| puts "Hello, #{item}" end end end greet = Greeter.new %w(world l...

git diff [HEAD|--staged...] --word-diff Rather than displaying lines changed, this will display differences within lines. For example, rather than: -Hello world +Hello world! Where the whole line is marked as changed, word-diff alters the output to: Hello [-world-]{+world!+} You can omit...

In this approach, the single is accessed via the static method: Singleton.getInstance(); To enforce only one instance of the singleton, a private static variable retains the instance, while any additional attempts to instantiate an instance are enforced within the constructor. package { publ...

Cocoa is Apple's API to develop apps for macOS, formerly known as OS X. Cocoa is a container framework, and contains three sub-frameworks. Foundation AppKit CoreData Cocoa Touch is Apple's version of Cocoa to develop apps for iOS, watchOS and tvOS. Cocoa Touch contains the same sub-framewo...

If you want to download an object from GCS that is publicly viewable, the simplest way is to use a web browser or a command line tool to fetch a URL with this pattern: https://storage.googleapis.com/bucketName/objectName. Example: https://storage.googleapis.com/pub/someOfTheTeam.jpg

You can use git merge --squash to squash changes introduced by a branch into a single commit. No actual commit will be created. git merge --squash <branch> git commit This is more or less equivalent to using git reset, but is more convenient when changes being incorporated have a symbolic...

add_filter('template_include', 'custom_function'); function custom_function($template){ /* * This example is a little more advanced. * It will check to see if $template contains our post-type in the path. * If it does, the theme contains a high level templat...
