System.Numerics.Vectors

System.Numerics.Vectors

System.Numerics.Vectors is a library of vector types that can take advantage of SIMD hardware-based acceleration. Hardware acceleration can result in significant performance improvements in mathematical, scientific, and graphics programming. System.Numerics.Vectors includes 2-dimensional, 3-dimensional, and 4-dimensional vectors of type Single. The generic Vector<T> structure allows you to create a vector of any primitive numeric type. (The primitive numeric types include all numeric types in the System namespace except for Decimal.) In addition, the Vector class provides a library of convenience methods that you can call when working with vectors. Also, System.Numerics.Vectors includes two matrix types: Matrix3x2, which represents a 3x2 matrix; and Matrix4x4, which represents a 4x4 matrix. In addition, System.Numerics.Vectors includes a Plane type and a Quaternion type.

Note 1: Vector<T> Structure represents a single vector of a specified numeric type that is suitable for low-level optimization of parallel algorithms. 

Note 2: System.Numerics.Vectors.WindowsRuntime provides extension methods for converting between System.Numerics.Vector2 and Windows.Foundation.Point and Size. Its commonly used type is: System.Numerics.VectorExtensions.

SIMD

SIMD

SIMD is short for Single Instruction/Multiple Data, while the term SIMD operations refers to a computing method that enables processing of multiple data with a single instruction. SIMD is a class of parallel computers in Flynn's taxonomy. It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Thus, such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but only a single process (instruction) at a given moment. SIMD is particularly applicable to common tasks like adjusting the contrast in a digital image or adjusting the volume of digital audio. Most modern CPU designs include SIMD instructions in order to improve the performance of multimedia use.

CSRF Protection: When It Breaks, It Breaks Very Quietly

CSRF Protection: When It Breaks, It Breaks Very Quietly

Cross-site request forgery (CSRF) is tricking the browser with a malicious (or compromised) site B to access something on site A.  Since requests for site A would include site A's cookie whether requested by A or not, an image tag or embedded JavaScript on site B can submit some requests on site A that a logged-in user can do, like accessing private info with the appropriate POST parameters to make it happen. Rails has a mechanism that defends against CSRF: all one should to do is include a few lines of code as:

class ApplicationController < ActionController::Base

  protect_from_forgery

end

class FooController < ApplicationController

  protect_from_forgery except: :index

Rails will then basically generate cryptographically secure random number, totally transparently to the developer; it is called the CSRF token.

AJAX To Send CSRF Token Authenticity

AJAX To Send CSRF Token Authenticity

To send CSRF (XSRF) token authenticity in all AJAX requests:

$.ajaxSetup({

     headers: { 

 'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content') 

 }});
