// this function add custom interval (5 minutes) to the $schedules function five_minutes_interval( $schedules ) { $schedules['five_minutes'] = array( 'interval' => 60 * 5, 'display' => '5 minutes'; ); return $schedules; } // add a custom in...
The hash codes produced by GetHashCode() method for built-in and common C# types from the System namespace are shown below. Boolean 1 if value is true, 0 otherwise. Byte, UInt16, Int32, UInt32, Single Value (if necessary casted to Int32). SByte ((int)m_value ^ (int)m_value << 8); Char...
Generally, it's not a good idea to use a regular expression to parse a complex structure. But it can be done. For instance, you might want to load data into hive table and fields are separated by comma but complex types like array are separated by a "|". Files contain records with all fiel...
Fluent methods in Kotlin can be the same as Java: fun doSomething() { someOtherAction() return this } But you can also make them more functional by creating an extension function such as: fun <T: Any> T.fluently(func: ()->Unit): T { func() return this } Which the...
The BukkitRunnable is a Runnable found in Bukkit. It's possible to schedule a task directly from a BukkitRunnable, and also cancel it from inside itself. Important: The time on the tasks is measured in Ticks. A second has 20 ticks. Non-RepeatingTask: JavaPlugin plugin; //Your plugin instance ...
Enable the module by typing: sudo a2enmod ssl Restart the web server (apache2) so the change is recognized: sudo service apache2 restart Optional (but a good idea): Create a directory that will contain our new certificate files: sudo mkdir /etc/apache2/ssl Create the key and self-signed ...
Pointers can be dereferenced by adding an asterisk * before a pointer. package main import ( "fmt" ) type Person struct { Name string } func main() { c := new(Person) // returns pointer c.Name = "Catherine" fmt.Println(c.Name) // prints: Cathe...
A question that occasionally on StackOverflow is whether it is appropriate to use assert to validate arguments supplied to a method, or even inputs provided by the user. The simple answer is that it is not appropriate. Better alternatives include: Throwing an IllegalArgumentException using cust...
You can have a config.yml file that loads directly from your jar file. It must be added to your project's folder, the same way as the plugin.yml file is. In this file you have the default values for your configuration. Example config: # This is an YML comment adminName: "Kerooker" mod...
Instead of getting a reference to the DOM you can simply change the index of the tab using the selectedIndex attribute on the ion-tabs HTML: <ion-tabs [selectedIndex]="tabIndex" class="tabs-icon-text" primary > <ion-tab tabIcon="list-box" [root]=&qu...

The WMI type provider allows you to query WMI services with strong typing. To output the results of a WMI query as JSON, open FSharp.Management open Newtonsoft.Json // `Local` is based off of the WMI available at localhost. type Local = WmiProvider<"localhost"> let data = ...
Classes implement an interface to meet the interface's contract. For example, a C# class may implement IDisposable, public class Resource : IDisposable { private MustBeDisposed internalResource; public Resource() { internalResource = new MustBeDisposed(); } ...

Slices are pointers to arrays, with the length of the segment, and its capacity. They behave as pointers, and assigning their value to another slice, will assign the memory address. To copy a slice value to another, use the built-in copy function: func copy(dst, src []Type) int (returns the amount o...
