It's a good practice to scope patches using Refinements, but sometimes it's nice to load it globally (for example in development, or testing). Say for example you want to start a console, require your library, and then have the patched methods available in the global scope. You couldn't do this wit...

Refinements have special limitations. refine can only be used in a module scope, but can be programmed using send :refine. using is more limited. It can only be called in a class/module definition. Still, it can accept a variable pointing to a module, and can be invoked in a loop. An example show...

func multiply2(item: Int)-> Int { return (item + 2) } let multiply2ToMe = multiply2 // passing the function directly to the function as param print(math.performOperation(inputArray: arrayToBeProcessed, operation: multiply2ToMe)) Output: [3, 5, 7, 9, 11, 13, 10, 8, 6, 4, 102] ...

Using the --remote-debugging-port to expose a debugger accessible over HTTP is one way appliances can connect and interact with the document using the Chrome Debugging Protocol. chrome --headless --remote-debugging-port=9222 https://stackoverflow.com You can then navigate to http://localhost:9222 ...

This example is was modeled after an example that I found on the internet. I can't find the link or I would give the author credit. I took the sample that I found and modified it to work for my application. Add the following references: System.Xaml, PresentationCore, PresentationFramework,...

You can't improve something you can't measure. To improve the performance of React components, you should be able to measure it. ReactJS provides with addon tools to measure performance. Import the react-addons-perf module to measure the performance import Perf from 'react-addons-perf' // ES6 var ...

Once you have everything prepared to write your Unit Tests it is worth to mention about mocking. There is new framework called "SimpleStubs" which enables you to create mocks based on the interfaces. Simple case from GitHub documentation: //Sample interface: public interface IPhoneBook ...

When you want for example enforce the use of the parameter Password if the parameter User is provided. (and vise versa) Function Do-Something { Param ( [Parameter(Mandatory=$true)] [String]$SomeThingToDo, [Parameter(ParameterSetName="Credentials", man...

Function Do-Something { Param ( [Parameter(Mandatory=$true)] [String]$SomeThingToDo, [Parameter(ParameterSetName="Silently", mandatory=$false)] [Switch]$Silently, [Parameter(ParameterSetName="Loudly", mandatory=$false)] ...

A synchronous producer-consumer solution ensures that the consumer reads every data item written by the producer exactly one time. Asynchronous solutions allow the consumer to sample the output of the producer. Either the consumer consumes the data faster than it is produced, or the consumer consume...

This example uses the main procedure as the producer task. In Ada the main procedure always runs in a task separate from all other tasks in the program, see minimal example. ------------------------------------------------------------------ -- Sampling Consumer -- --------------------------------...

You can source configuration from environment variables by calling .AddEnvironmentVariables() on you ConfigurationBuilder. It will load environment variables prefixed with APPSETTING_ It will then use colon : as the key path separator. This means that : following environement settings : APPSETTI...

You can also source configuration from an in memory object such as a Dictionary<string,string> .AddInMemoryCollection(new Dictionary<string, string> { ["akey"] = "a value" }) This can reveal helpful in integration/unit testing scenarios.

In order to be able to directly deploy web project changes to an Web Server, the following steps must be followed. If target server has Internet access, the process is quite simple, as Microsoft has a Web Platform package to do almost everything that is needed. Cleanup Make sure that C:\Progra...

Fully configuration of Web deployment without Internet connection (offline) is harder to make because Web platform installer (UI) operates by querying packages list and content from an Internet location. Cleanup Make sure that C:\Program Files\IIS does not contain older version of Microsoft We...

The Java Native Interface (JNI) allows you to call Java functions from native code. Here is a simple example of how to do it: Java code: package com.example.jniexample; public class JNITest { public static int getAnswer(bool) { return 42; } } Native code: int getTheAnswer(...
