Problem: You need to match text of a certain format, for example: 1-a-0 6/p/0 4 g 0 That's a digit, a separator (one of -, /, or a space), a letter, the same separator, and a zero. Naïve solution: Adapting the regex from the Basics example, you come up with this regex: [0-9]([-/ ])[a-z]\...

Following script illustrates how to receive events according to visibility to a set camera. This script uses several performance heavy methods for brevity. using UnityEngine; using System.Linq; public class CullingGroupCameraBehaviour : MonoBehaviour { CullingGroup localCullingGroup;...

The regular composition works for unary functions. In the case of binary, we can define (f .: g) x y = f (g x y) -- which is also = f ((g x) y) = (f . g x) y -- by definition of (.) = (f .) (g x) y = ((f .) . g) x y Thus,...

Meteor uses Cordova to package your application into a hybrid Mobile App. Once packaged, the App can be distributed like native Apps (through Apple App Store, Google Play Store, etc.) Add the target platform(s) to your Meteor project: meteor add-platform android meteor add-platform ios # Only...

Considering a (post)model: public class User { public string FirstName { get; set; } public bool IsAdmin { get; set; } } With a view like so: @using (Html.BeginForm()) { @Html.EditorFor(model => model.FirstName) <input type="submit" value="Save" /...

A bibtex catalogue cna easily be included with the YAML option bibliography:. A certain style for the bibliography can be added with biblio-style:. The references are added at the end of the document. --- title: "Including Bibliography" author: "John Doe" output: pdf_documen...

In a statically typed language like F# we work with types well-known at compile-time. We consume external data sources in a type-safe manner using type providers. However, occassionally there's need to use late binding (like dynamic in C#). For instance when working with JSON documents that have...

The simplest way to get an event handler called on a key press is to connect the handler to the key-press-event signal. In this example, we register for the event for the whole window, but you can also register for individual widgets too. The most important part is the connection of the handler to ...

The number that follows the associativity information describes in what order the operators are applied. It must always be between 0 and 9 inclusive. This is commonly referred to as how tightly the operator binds. For example, consider the following fixity declarations (in base) infixl 6 + infixl ...

If the shift count value is a negative value then both left shift and right shift operations are undefined1: int x = 5 << -3; /* undefined */ int x = 5 >> -3; /* undefined */ If left shift is performed on a negative value, it's undefined: int x = -5 << 3; /* undefined */ I...

Pressing C-h a will run the emacs function apropos-command which makes emacs prompt for words (or a regexp) to search for. It will then show a buffer containing a list of names and descriptions related to that topic, including key bindings for each of the functions available via keystrokes. Pressin...

C-h k runs the function describe-key, which looks up the function mapped to the key strokes provided, and presents a description of the function which will be run when these keys are pressed. C-h c runs the function describe-key-briefly, which only displays the function name mapped to given key seq...

Binaries in elixir are created using the Kernel.SpecialForms construct <<>>. They are a powerful tool which makes Elixir very useful for working with binary protocols and encodings. Binaries and bitstrings are specified using a comma delimited list of integers or variable values, booke...

A few pre-requisites in the build.gradle for vectors to work all the way down to API 7 for VectorDrawables and API 13 for AnimatedVectorDrawables (with some caveats currently): //Build Tools has to be 24+ buildToolsVersion '24.0.0' defaultConfig { vectorDrawables.useSupportLibrary = true ...

If you want to Download image as Bitmap using Picasso following code will help you: Picasso.with(mContext) .load(ImageUrl) .into(new Target() { @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) { // Todo: Do some...

Arrow functions are lexically scoped; this means that their this Binding is bound to the context of the surrounding scope. That is to say, whatever this refers to can be preserved by using an arrow function. Take a look at the following example. The class Cow has a method that allows for it to pr...
