[TimeStamp] attribute can be applied to only one byte array property in a given Entity class. Entity Framework will create a non-nullable timestamp column in the database table for that property. Entity Framework will automatically use this TimeStamp column in concurrency check. using System.Compon...

It can be difficult to test functions with poor asymptotic complexity using quickcheck as the random inputs are not usually size bounded. By adding an upper bound on the size of the input we can still test these expensive functions. import Data.List(permutations) import Test.QuickCheck longRunn...

We can create a Map from a list of tuples like this: Map.fromList [("Alex", 31), ("Bob", 22)] A Map can also be constructed with a single value: > Map.singleton "Alex" 31 fromList [("Alex",31)] There is also the empty function. empty :: Map k a ...

We can wrap a class decorator with another function to allow customization: function addMetadata(metadata: any) { return function log(target: any) { // Add metadata target.__customMetadata = metadata; // Return target return target; ...

Constructors are special methods named after the class and without a return type, and are used to construct objects. Constructors, like methods, can take input parameters. Constructors are used to initialize objects. Abstract classes can have constructors also. public class Hello{ // construct...

Normally, to remove files that are staged to be committed using the git reset commit, reset has a lot of functions depending on the arguments provided to it. To completely unstage all files staged, we can make use of git aliases to create a new alias that uses reset but now we do not need to remembe...

impl<K, V> Serialize for MyMap<K, V> where K: Serialize, V: Serialize { fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where S: Serializer { let mut state = serializer.serialize_map(Some(self.len()))?; ...

// A Visitor is a type that holds methods that a Deserializer can drive // depending on what is contained in the input data. // // In the case of a map we need generic type parameters K and V to be // able to set the output type correctly, but don't require any state. // This is an example of a...

In build.sbt, make sure you include (here for Mysql and PostGreSQL): "mysql" % "mysql-connector-java" % "5.1.20", "org.postgresql" % "postgresql" % "9.3-1100-jdbc4", "com.typesafe.slick" %% "slick" % "3.1.1&...

Shortcode is a small piece of code that can be added into the WordPress editor and will output something different once the page is published or previewed. Frequently, shortcodes are added to the theme functions.php file, but that's not a good practice as shortcodes are expected to keep working aft...

A function that is declared constexpr is implicitly inline and calls to such a function potentially yield constant expressions. For example, the following function, if called with constant expression arguments, yields a constant expression too: C++11 constexpr int Sum(int a, int b) { return ...
