Global basis: Blueprint API configuration is defined in /config/blueprint.js file. You can enable or disable all three types of blueprint routes for all controllers from there. As example, if you want to disable blueprint shortcut routes for all of your controllers but want to keep both acti...

To print the value of a pointer to an object (as opposed to a function pointer) use the p conversion specifier. It is defined to print void-pointers only, so to print out the value of a non void-pointer it needs to be explicitly converted ("casted*") to void*. #include <stdlib.h> /*...

PHP provides support for the HTTP PUT method used by some clients to store files on a server. PUT requests are much simpler than a file upload using POST requests and they look something like this: PUT /path/filename.html HTTP/1.1 Into your PHP code you would then do something like this: <?p...

Sometimes we need to fetch and print the value of a TensorFlow variable to guarantee our program is correct. For example, if we have the following program: import tensorflow as tf import numpy as np a = tf.Variable(tf.random_normal([2,3])) # declare a tensorflow variable b = tf.random_normal([2...

When dealing with an unbalanced design and/or non-orthogonal contrasts, Type II or Type III Sum of Squares are necessary. The Anova() function from the car package implements these. Type II Sum of Squares assumes no interaction between main effects. If interactions are assumed, Type III Sum of Squar...

The current frame rate (in FPS, Frames Per Second) and total number of SKNodes in the scene (nodeCount, each sprite is an SKNode but other objects in the scene are also SKNodes) can be shown in the bottom right hand corner of the view. These can be useful when turned on (set to true) for debugging ...

An SKView does not need to fill the whole screen and can share space with other UI controls. You can even have more than one SKView displayed at once if you wish. To create a smaller SKView amongst other controls with Interface Builder, first create a normal ViewController, then drag and drop a new...

When a function returns an object (as opposed to using one that's passed in by the caller), be careful an exception doesn't cause the object to leak. function MakeStrings: TStrings; begin // Create a new object before entering the try-block. Result := TStringList.Create; try // Execu...

The angular.copy function takes an object, array or a value and creates a deep copy of it. angular.copy() Example: Objects: let obj = {name: "vespa", occupation: "princess"}; let cpy = angular.copy(obj); cpy.name = "yogurt" // obj = {name: "vespa", ...

In order to print the value of a variable such as, set tempVar "This is a string." The argument in the puts statement is preceded by a $ sign, which tells Tcl to use the value of the variable. % set tempVar "This is a string." This is a string. % puts $tempVar This is a s...

We can use org.apache.commons.lang3.RandomUtils to generate random numbers using a single line. int x = RandomUtils.nextInt(1, 1000); The method nextInt(int startInclusive, int endExclusive) takes a range. Apart from int, we can generate random long, double, float and bytes using this class. R...

What happens if I don't set base_url ? You will not get any Impotency error to set this and proceed. You can continue without setting, but you should know about HTTP header injection If I did't set it what will show up? You will get http://[::1]/ instead of your actual URL. What does this m...

Any project that targets netstandard1.X can be packed into a NuGet package by running: dotnet pack The resulting package can be uploaded to NuGet, MyGet, or hosted in a local package source.

This example describes how to create a SurfaceView with a dedicated drawing thread. This implementation also handles edge cases such as manufacture specific issues as well as starting/stopping the thread to save cpu time. import android.content.Context; import android.graphics.Canvas; import and...

If you want to write strings containing other languages (JSON, regexes), it's hard to keep up with escaping symbols, and it would be nice to get some code assist. Put your cursor inside an empty string ALT + ENTER Pick "Inect language or reference" Pick the desirable language (...

When using clustered index, the rows of the table are sorted by the column to which the clustered index is applied. Therefore, there can be only one clustered index on the table because you can't order the table by two different columns. Generally, it is best to use clustered index when performing ...

Nonclustered indexes are stored separately from the table. Each index in this structure contains a pointer to the row in the table which it represents. This pointers are called a row locators. The structure of the row locator depends on whether the data pages are stored in a heap or a clustered tab...

Below code showcases multiple Producer/Consumer program. Both Producer and Consumer threads share same global queue. import java.util.concurrent.*; import java.util.Random; public class ProducerConsumerWithES { public static void main(String args[]) { BlockingQueue<Integer> ...
