The simplest approach to the problem (and the most commonly used so far) is to split sentences into tokens. Simplifying, words have abstract and subjective meanings to the people using and receiving them, tokens have an objective interpretation: an ordered sequence of characters (or bytes). Once sen...

The core data structure in numpy is the ndarray (short for n-dimensional array). ndarrays are homogeneous (i.e. they contain items of the same data-type) contain items of fixed sizes (given by a shape, a tuple of n positive integers that specify the sizes of each dimension) One-dimensional ar...

Open Visual Studio Select File --> New --> Project menu or push Ctrl + Shift + N buttons Select Outlook VSTO Add-in template Add the following code to the project: private void ThisAddIn_Startup(object sender, System.EventArgs e) { MessageBox.Show("Hel...

Associated objects are useful when you want to add functionality to existing classes which requires holding state. For example, adding a activity indicator to every UIView: Objective-C Implementation #import <objc/runtime.h> static char ActivityIndicatorKey; @implementation UIView (Ac...

Integral type ranges ( IntRange , LongRange , CharRange ) have an extra feature: they can be iterated over. The compiler takes care of converting this analogously to Java's indexed for-loop, without extra overhead for (i in 1..4) print(i) // prints "1234" for (i in 4..1) print(i) // pri...

if you want to iterate over numbers in reverse order? It's simple. You can use the downTo() function defined in the standard library for (i in 4 downTo 1) print(i) // prints "4321"

Is it possible to iterate over numbers with arbitrary step, not equal to 1? Sure, the step() function will help you for (i in 1..4 step 2) print(i) // prints "13" for (i in 4 downTo 1 step 2) print(i) // prints "42"

To create a range which does not include its end element, you can use the until function: for (i in 1 until 10) { // i in [1, 10), 10 is excluded println(i) }

By default structures are padded in C. If you want to avoid this behaviour, you have to explicitly request it. Under GCC it's __attribute__((__packed__)). Consider this example on a 64-bit machine: struct foo { char *p; /* 8 bytes */ char c; /* 1 byte */ long x; /* 8 bytes */ ...

This will be a very basic app which will illustrate different ModalpresentationStyle in iOS. According to documentation found here, There are 9 different values for UIModalPresentationStyle which are as follows, fullScreen pageSheet formSheet currentContext custom overFullScreen overCurrent...

When generating new Angular 2 components in a .NET Core project, you may run into the following errors (as of version 0.8.3): Error locating module for declaration SilentError: No module files found OR No app module found. Please add your new Class to your component. Identica...

Like other value types, GUID also has a nullable type which can take null value. Declaration : Guid? myGuidVar = null; This is particularly useful when retrieving data from the data base when there is a possibility that value from a table is NULL.

const foop = { get value() {}, set value(v) {} }; it('can spy on getter', () => { spyOnProperty(foop, 'value', 'get').and.returnValue(1); expect(foop.value).toBe(1); }); it('and on setters', () => { const spiez = spyOnProperty(foop, 'value', 'set'); foop.v...

Dim rng As New Random() This declares an instance of the Random class called rng. In this case, the current time at the point where the object is created is used to calculate the seed. This is the most common usage, but has its own problems as we shall see later in the remarks Instead of allowin...

The following example declares a new instance of the Random class and then uses the method .Next to generate the next number in the sequence of pseudo-random numbers. Dim rnd As New Random Dim x As Integer x = rnd.Next The last line above will generate the next pseudo-random number and assign ...

The following features added in SQL Server 2000 from its previous version: New data types were added (BIGINT, SQL_VARIANT, TABLE) Instead of and for Triggers were introduced as advancement to the DDL. Cascading referential integrity. XML support User defined functions and partition views. In...
