Objects come in their own class, so a simple example would be a car (detailed explanations below):
public class Car {
//Variables describing the characteristics of an individual car, varies per object
private int milesPerGallon;
private String name;
private String color;

Preconnect
The preconnect relationship is similar to dns-prefetch in that it will resolve the DNS. However, it will also make the TCP handshake, and optional TLS negotiation.
This is an experimental feature.

Suppose you have a hot observable for which you would love to keep the count of. It could be the IObservable<StockTick> and you want to keep count of the average trade volume. You can use Scan for that.
var tradeVolume = stockTicks.Select(e => e.Price)
.Scan(0.0m, (aggregated, newtick...
Development and Evaluation Installations
Alfresco provides a number of different installers for different operating systems and platforms. However, these installers are not recommended for production environments.

When you run sails lift with blueprints enabled, the framework inspects your
controllers, models, and configuration in order to bind certain routes automatically. These implicit blueprint routes allow your app to respond
to certain requests without you having to bind those routes manually in your
...
Blueprint actions (not to be confused with blueprint action routes) are
generic actions designed to work with any of your controllers that have a model
of the same name (e.g. ParrotController would need a Parrot model). Think of
them as the default behavior for your application. For instance, if...
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...
set alpha 1
proc myproc {} {
puts $alpha
}
myproc
This code doesn't work because the two alphas are in different scopes.
The command set alpha 1 creates a variable in the global scope (which makes it a global variable).
The command puts $alpha is executed in a scope that is created ...
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...
Python programs can read from unix pipelines. Here is a simple example how to read from stdin:
import sys
for line in sys.stdin:
print(line)
Be aware that sys.stdin is a stream. It means that the for-loop will only terminate when the stream has ended.
You can now pipe the output of anot...
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...
Consider the following three equations:
x0 + 2 * x1 + x2 = 4
x1 + x2 = 3
x0 + x2 = 5
We can express this system as a matrix equation A * x = b with:
A = np.array([[1, 2, 1],
[0, 1, 1],
[1, 0, 1]])
b = np.array([4, 3, 5])
Then, use np.linalg....
Create a select list that can be used to choose a single or multiple items from a list of values.
library(shiny)
ui <- fluidPage(

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...
In Tcl itself, a string consisting of a single word does not need to be quoted. In the language of expression strings that expr evaluates, all operands must have an identifiable type.
Numeric operands are written without any decoration:
expr {455682 / 1.96e4}
So are boolean constants:
expr {tr...
