Informally, a monad is a container of elements, notated as F[_], packed with 2 functions: flatMap (to transform this container) and unit (to create this container). Common library examples include List[T], Set[T] and Option[T]. Formal definition Monad M is a parametric type M[T] with two operatio...

Returns an int value representing the ASCII code of the leftmost character of a string. SELECT ASCII('t') -- Returns 116 SELECT ASCII('T') -- Returns 84 SELECT ASCII('This') -- Returns 84 If the string is Unicode and the leftmost character is not ASCII but representable in the current collatio...

Returns the start index of a the first occurrence of string expression inside another string expression. Parameters list: String to find (up to 8000 chars) String to search (any valid character data type and length, including binary) (Optional) index to start. A number of type int or big int. ...

Returns a char represented by an int ASCII code. SELECT CHAR(116) -- Returns 't' SELECT CHAR(84) -- Returns 'T' This can be used to introduce new line/line feed CHAR(10), carriage returns CHAR(13), etc. See AsciiTable.com for reference. If the argument value is not between 0 and 255, the CHAR...

SQL Server 2012 Returns a string that is the result of two or more strings joined together. CONCAT accepts two or more arguments. SELECT CONCAT('This', ' is', ' my', ' string') -- returns 'This is my string' Note: Unlike concatenating strings using the string concatenation operator (+), when ...

Returns the Unicode character(s) (nchar(1) or nvarchar(2)) corresponding to the integer argument it receives, as defined by the Unicode standard. Parameters: integer expression. Any integer expression that is a positive number between 0 and 65535, or if the collation of the database supports sup...

An interface contains the signatures of methods, properties and events. The derived classes defines the members as the interface contains only the declaration of the members. An interface is declared using the interface keyword. interface IProduct { decimal Price { get; } } class Product...

By default, plot() creates a new figure each time it is called. It is possible to plot on an existing axis by passing the ax parameter. plt.figure() # create a new figure ax = plt.subplot(121) # create the left-side subplot df1.plot(ax=ax) # plot df1 on that subplot ax = plt.subplot(122) # c...

All integers or pointers can be used in an expression that is interpreted as "truth value". int main(int argc, char* argv[]) { if (argc % 4) { puts("arguments number is not divisible by 4"); } else { puts("argument number is divisible by 4"); } ... ...

ScopedTypeVariables let you refer to universally quantified types inside of a declaration. To be more explicit: import Data.Monoid foo :: forall a b c. (Monoid b, Monoid c) => (a, b, c) -> (b, c) -> (a, b, c) foo (a, b, c) (b', c') = (a :: a, b'', c'') where (b'', c'') = (b <&g...

If an array happens to have one or more nil elements and these need to be removed, the Array#compact or Array#compact! methods can be used, as below. array = [ 1, nil, 'hello', nil, '5', 33] array.compact # => [ 1, 'hello', '5', 33] #notice that the method returns a new copy of the array w...

The code sample below shows one way to retrieve records from an MSSql Server in a background thread using FireDAC. Tested for Delphi 10 Seattle As written: The thread retrieves data using its own TFDConnection and TFDQuery and transfers the data to the form's FDQuery in a call to Sychronize...

In this example, a model will learn to classify fruits given certain features, using the Labels for training.

PHP's source code is hosted on GitHub. To build from source you will first need to check out a working copy of the code. mkdir /usr/local/src/php-7.0/ cd /usr/local/src/php-7.0/ git clone -b PHP-7.0 https://github.com/php/php-src . If you want to add a feature, it's best to create your own bra...

We can use flatten() in order to lazily reduce the nesting of a multi-dimensional sequence. For example, lazy flattening a 2D array into a 1D array: // A 2D array of type [[Int]] let array2D = [[1, 3], [4], [6, 8, 10], [11]] // A FlattenBidirectionalCollection<[[Int]]> let lazilyFlatten...

Melting: The basics Melting is used to transform data from wide to long format. Starting with a wide data set: DT = data.table(ID = letters[1:3], Age = 20:22, OB_A = 1:3, OB_B = 4:6, OB_C = 7:9) We can melt our data using the melt function in data.table. This returns another data.table in long...

To create a libary , you should use File -> New -> New Module -> Android Library. This will create a basic library project. When that's done, you must have a project that is set up the following manner: [project root directory] [library root directory] [gradle] build.gradle...

To use the library, you must include it as a dependency with the following line: compile project(':[library root directory]')

Perform the following steps to create the library: Create a GitHub account. Create a Git repository containing your library project. Modify your library project's build.gradle file by adding the following code: apply plugin: 'com.github.dcendents.android-maven' ... // Build a j...
