C++11 The alignas keyword can be used to force a variable, class data member, declaration or definition of a class, or declaration or definition of an enum, to have a particular alignment, if supported.

This class is called Greeter. Its responsibility is to output a greeting. It has two dependencies. It needs something that will give it the greeting to output, and then it needs a way to output that greeting. Those dependencies are both described as interfaces, IGreetingProvider and IGreetingWriter....

This builds on the previous example of the Greeter class which has two dependencies, IGreetingProvider and IGreetingWriter. The actual implementation of IGreetingProvider might retrieve a string from an API call or a database. The implementation of IGreetingWriter might display the greeting in the ...

Dependency injection means writing classes so that they do not control their dependencies - instead, their dependencies are provided to them ("injected.") This is not the same thing as using a dependency injection framework (often called a "DI container", "IoC container&quo...

Basically you can use type inference whenever it is possible. However, be careful when combining Option Infer Off and Option Strict Off, as this can lead to undesired run-time behavior: Dim someVar = 5 someVar.GetType.ToString() '--> System.Int32 someVar = "abc" someVar.GetType.To...

There is an example of listing content : tar -tvf archive.tar The option -t is used for the listing. For listing the content of a tar.gz archive, you have to use the -z option anymore : tar -tzvf archive.tar.gz

Orders a collection by a specified value. When the value is an integer, double or float it starts with the maximal value, which means that you get first the positive values, than zero and afterwords the negative values (see Example 1). When you order by a char the method compares the ascii val...

YAML does not come with a standard PHP installation, instead it needs to be installed as a PECL extension. On linux/unix it can be installed with a simple pecl install yaml Note that libyaml-dev package must be installed on the system, as the PECL package is simply a wrapper around libYAML call...

This is relevant for apps that implement a BootListener. Test your app by killing your app and then test with: adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n your.app/your.app.BootListener (replace your.package/your.app.BootListener with proper ...
