Automapper can be installed from nuget running the following command in Package Manager Console: Install-Package AutoMapper Then it can be included in different files within the project it has been installed to by using directives: using AutoMapper;

Using Alternatives Many Linux distributions use the alternatives command for switching between different versions of a command. You can use this for switching between different versions of Java installed on a machine. In a command shell, set $JDK to the pathname of a newly installed JDK; e.g....

es = Elasticsearch(hosts=hosts, sniff_on_start=True, sniff_on_connection_fail=True, sniffer_timeout=60, sniff_timeout=10, retry_on_timeout=True)

The standard Ada programming language is defined in the Ada Reference Manual. Interim version changes and release notes are discussed in the corresponding rationale documents. Implementations typically document their compliance with the standard in the form of a user guide and/or reference manual, f...

Using requestAnimationFrame may on some systems update at more frames per second than the 60fps. 60fps is the default rate if the rendering can keep up. Some systems will run at 120fps maybe more. If you use the following method you should only use frame rates that are integer divisions of 60 so th...

First, let's see three different ways of extracting data from a file. string fileText = File.ReadAllText(file); string[] fileLines = File.ReadAllLines(file); byte[] fileBytes = File.ReadAllBytes(file); On the first line, we read all the data in the file as a string. On the second line, we r...

Iterating over connected serial ports using System.IO.Ports; string[] ports = SerialPort.GetPortNames(); for (int i = 0; i < ports.Length; i++) { Console.WriteLine(ports[i]); } Instantiating a System.IO.SerialPort object using System.IO.Ports; SerialPort port = new SerialPort(); ...

A conversion that involves calling an explicit constructor or conversion function can't be done implicitly. We can request that the conversion be done explicitly using static_cast. The meaning is the same as that of a direct initialization, except that the result is a temporary. class C { std:...

static_cast can perform any implicit conversion. This use of static_cast can occasionally be useful, such as in the following examples: When passing arguments to an ellipsis, the "expected" argument type is not statically known, so no implicit conversion will occur. const double x = ...

You can use built-in functions to run PHP processes as forks. This is the most simple way to achieve parallel work if you don't need your threads to talk to each other. This allows you to put time intensive tasks (like uploading a file to another server or sending an email) to another thread so you...

1 Tag Name Represents a tag name available in the DOM. For example $('p') selects all paragraphs <p> in the document. 2 Tag ID Represents a tag available with the given ID in the DOM. For example $('#some-id') selects the single element in the document that has an ID of some-id. 3 ...

static_cast can convert from an integer or floating point type to an enumeration type (whether scoped or unscoped), and vice versa. It can also convert between enumeration types. The conversion from an unscoped enumeration type to an arithmetic type is an implicit conversion; it is possible, but ...

A pointer to member of derived class can be converted to a pointer to member of base class using static_cast. The types pointed to must match. If the operand is a null pointer to member value, the result is also a null pointer to member value. Otherwise, the conversion is only valid if the member ...

Generally execute() command is used for fire and forget calls (without need of analyzing the result) and submit() command is used for analyzing the result of Future object. We should be aware of key difference of Exception Handling mechanisms between these two commands. Exceptions from submit() ar...

Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF or XSRF, is a type of malicious exploit of a website where unauthorized commands are transmitted from a user that the website trusts. Learn more To enable CSRF protection, add the CsrfViewMid...

Detailed instructions on getting kettle set up or installed.

Python3 - sudo pip3 install tornado Python2 - sudo pip install tornado Packages which will are optional but recommended to install alongside Tornado : concurrent.futures pycurl pycares Twisted monotonic or monotime

C99 Since C99 the C library has a set of safe conversion functions that interpret a string as a number. Their names are of the form strtoX, where X is one of l, ul, d, etc to determine the target type of the conversion double strtod(char const* p, char** endptr); long double strtold(char const* p...

Official documentation: http://erlang.org/doc/tutorial/nif.html NIFs were introduced in Erlang/OTP R13B03 as an experimental feature. The purpose is to allow calling C-code from inside Erlang code. NIFs are implemented in C instead of Erlang, but they appear as any other functions in the scope of ...

Starting with Java 8, you can use lambda expressions & predicates. Example: Use a lambda expressions & a predicate to get a certain value from a list. In this example every person will be printed out with the fact if they are 18 and older or not. Person Class: public class Person { p...
