When we use @SpringApplicationConfiguration it will use configuration from application.yml [properties] which in certain situation is not appropriate. So to override the properties we can use @TestPropertySource annotation. @TestPropertySource( properties = { "spring...

In order to compare query sequences against reference sequences, you must create a blastdb of your reference(s). This is done using makeblastdb which is included when you install blast. makeblastdb -in <input fasta> -dbtype nucl -out <label for database> So if you had a file referen...

This is an example of an implementation of the identity monad in JavaScript, and could serve as a starting point to create other monads. Based on the conference by Douglas Crockford on monads and gonads Using this approach reusing your functions will be easier because of the flexibility this monad...

In this example, a destructor is explicitly invoked for an object that will later be automatically destroyed. struct S { ~S() { std::cout << "destroying S\n"; } }; int main() { S s; s.~S(); } // UB: s destroyed a second time here A similar issue occurs when a st...

This simple example shows how to start multiple threads in Java. Note that the threads are not guaranteed to execute in order, and the execution ordering may vary for each run. public class HelloMultithreading { public static void main(String[] args) { for (int i = 0; i < 10; i...

First you need to load the email library. Do this either in the controller file that will be sending the email: $this->load->library('email'); Or load it globally in the autoload.php file in the config folder: $autoload['libraries'] = array('email'); While you're there, you may want t...

This basic example shows how an application can instantiate a classloader and use it to dynamically load a class. URL[] urls = new URL[] {new URL("file:/home/me/extras.jar")}; Classloader loader = new URLClassLoader(urls); Class<?> myObjectClass = loader.findClass("com.exampl...

This example combines multiple variants of MonoBehaviour singletons found on the internet into one and let you change its behavior depending on global static fields. This example was tested using Unity 5. To use this singleton, all you need to do is extend it as follows: public class MySingleton ...

To use additional packages within the Rcpp ecosystem, the correct header file may not be Rcpp.h but Rcpp<PACKAGE>.h (as e.g. for RcppArmadillo). It typically needs to be imported and then the dependency is stated within // [[Rcpp::depends(Rcpp<PACKAGE>)]] Examples: // Use the RcppAr...
