A Threadpool has a Queue of tasks, of which each will be executed on one these Threads. The following example shows how to add two int arrays using a Threadpool. Java SE 8 int[] firstArray = { 2, 4, 6, 8 }; int[] secondArray = { 1, 3, 5, 7 }; int[] result = { 0, 0, 0, 0 }; ExecutorService po...

When committing changes it is possible to specify that the commit will in future be squashed to another commit and this can be done like so, git commit --squash=[commit hash of commit to which this commit will be squashed to] One might also use, --fixup=[commit hash] alternatively to fixup. It is...

What you need is to get an entitlements file so the app can access your iCloud and write records using CloudKit. Follow the steps to grant access to iCloud from your app: 1- Select the project in the Project Navigator, and then open the General tab. 2- In the Identity section, set your developer ...

Given a Day, we can perform simple arithmetic and comparisons, such as adding: import Data.Time addDays 1 (fromGregorian 2000 1 1) -- 2000-01-02 addDays 1 (fromGregorian 2000 12 31) -- 2001-01-01 Subtract: addDays (-1) (fromGregorian 2000 1 1) -- 1999-12-31 addDays (-1) (fromGregorian...

Like Getting a result from another Activity you need to call the Fragment's method startActivityForResult(Intent intent, int requestCode). note that you should not call getActivity().startActivityForResult() as this will take the result back to the Fragment's parent Activity. Receiving the result c...

This program draws some shapes and 'hello world!' and let an image go to every corner of the window. the complete code: import pygame,sys from pygame.locals import * pygame.init() FPS = 30 #frames per second setting fpsClock = pygame.time.Clock() #set up the window screen = pygame.disp...

EditableAttribute sets whether users should be able to change the value of the class property. public class Employee { [Editable(false)] public string FirstName { get; set; } } Simple usage example in XAML application <Window x:Class="WpfApplication.MainWindow" ...

The two mapAccum functions combine the operations of folding and mapping. -- A Traversable structure -- | -- A seed value | ...

Charts can be created by working directly with the Series object that defines the chart data. In order to get to the Series without an exisitng chart, you create a ChartObject on a given Worksheet and then get the Chart object from it. The upside of working with the Series object is that you can s...

The starting point for the vast majority of charting code is to create an empty Chart. Note that this Chart is subject to the default chart template that is active and may not actually be empty (if the template has been modified). The key to the ChartObject is determining its location. The syntax...

A tuple is a heterogeneous collection of two to twenty-two values. A tuple can be defined using parentheses. For tuples of size 2 (also called a 'pair') there's an arrow syntax. scala> val x = (1, "hello") x: (Int, String) = (1,hello) scala> val y = 2 -> "world" y:...

x = np.random.random([100,100]) x.tofile('/path/to/dir/saved_binary.npy') y = fromfile('/path/to/dir/saved_binary.npy') z = y.reshape(100,100) all(x==z) # Output: # True

// application/controllers/Company_controller.php <?php if(!defined('BASEPATH')) exit('No direct script access allowed'); class Company_controller extends CI_Controller { public function __construct() { parent::__construct(); $this->load->model('companies_mo...

There are two approaches for influencing when a memory cleanup is performed. They are influencing how often the automatic process is performed and the other is manually triggering a cleanup. The garbage collector can be manipulated by tuning the collection thresholds which affect the frequency at w...

(Caveat emptor: there are many, many programmers who go into absolute conniptions if they meet code that uses recordsets instead of commands and stored procedures.) <% dim rs, sql dim SelectedUser SelectedUser = request.form("user") if IsNumeric(SelectedUser) then SelectedUser...

The syntax for using the aws cli is as follows: aws [options] <command> <subcommand> [parameters] Some examples using the 'ec2' command and the 'describe-instances' subcommand: aws ec2 describe-instances aws ec2 describe-instances --instance-ids <your-id> Example with a ...

ActionMailer also allows attaching files. attachments['filename.jpg'] = File.read('/path/to/filename.jpg') By default, attachments will be encoded with Base64. To change this, you can add a hash to the attachments method. attachments['filename.jpg'] = { mime_type: 'application/gzip', enco...

Using Ubuntu you have different ways to read a text file, all similar but useful in different context. cat This is the simplest way to read a text file; it simply output the file content inside the terminal. Be careful: if the file is huge, it could take some time to complete the printing process!...

public static string CreateBLOBContainer(string containerName) { try { string result = string.Empty; CloudMediaContext mediaContext; mediaContext = new CloudMediaContext(mediaServicesAccountName, mediaServicesAccou...

Sometimes conversion of primitive types to boxed types is necessary. To convert the array, it's possible to use streams (in Java 8 and above): Java SE 8 int[] primitiveArray = {1, 2, 3, 4}; Integer[] boxedArray = Arrays.stream(primitiveArray).boxed().toArray(Integer[]::new); With lowe...
