Go to the following registry subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber

Type the new port number and then click OK.

Li-Fi

Li-Fi 

Li-Fi (Light Fidelity) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. Coined by Prof. Harald Haas, Li-Fi is a subset of optical wireless communications (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. For now, long restricted to the academic domain, Li-Fi, a light-based data delivery method is suddenly getting all sorts of attention. An Estonian startup Velmenni recently tested an commercial implementation and found it to be superior to Wi-Fi in almost every way – except as something you and I will probably ever use. Velmenni’s technology, called Jungru, uses an LED bulb and transmits data at gigabit speed. It has a theoretical speed of 224 gigabytes per second, the BBC reported. While the Jungru product is commercially viable, it is still based on what seems to be a laboratory-grade MATLAB and Simulink setup paired with photodiodes as opposed to a final product which must transmit data in real world environments full of light pollution and other variables.

What is WebAssembly?

What is WebAssembly?

WebAssembly or wasm is an experimental efficient low-level programming language for in-browser client-side scripting, which is currently in development. Its initial aim is to support C/C++, though other languages are also intended to be supported. WebAssembly is a portable abstract syntax tree which is designed to be faster to parse than JavaScript, as well as faster to execute. The initial version of WebAssembly will be based on asm.js and PNaCl. The team working on WebAssembly includes people from Mozilla, Google, Microsoft, and Apple (who respectively control the four major browsers, Firefox, Chrome, Internet Explorer, and Safari). In summary,WebAssembly is:

⌂ An improvement to JavaScript: Implement your performance critical stuff in wasm and import it like a standard JavaScript module.

⌂ A new language: WebAssembly code defines an AST (so does JavaScript) represented in a binary format. You can author and debug in a text format so it’s readable.

⌂ A browser improvement: Browsers will understand the binary format, which means we’ll be able to compile binary bundles that compress smaller than the text JavaScript we use today. Smaller payloads mean faster delivery. Depending on compile-time optimization opportunities, WebAssembly bundles may run faster than JavaScript.

⌂ A Compile Target: A way for other languages to get first-class binary support across the entire web platform stack.

Expect the contents of this repository to be in flux: everything is still under discussion:

⌂ WebAssembly is efficient and fast: The wasm AST is designed to be encoded in a size- and load-time-efficient binary format. WebAssembly aims to execute at native speed by taking advantage of common hardware capabilities available on a wide range of platforms.

⌂ WebAssembly is safe: WebAssembly describes a memory-safe, sandboxed execution environment that may even be implemented inside existing JavaScript virtual machines. When embedded in the web, WebAssembly will enforce the same-origin and permissions security policies of the browser.

⌂ WebAssembly is open and debuggable: WebAssembly is designed to be pretty-printed in a textual format for debugging, testing, experimenting, optimizing, learning, teaching, and writing programs by hand. The textual format will be used when viewing the source of wasm modules on the web.

⌂ WebAssembly is part of the open web platform: WebAssembly is designed to maintain the versionless, feature-tested, and backwards-compatible nature of the web. WebAssembly modules will be able to call into and out of the JavaScript context and access browser functionality through the same Web APIs accessible from JavaScript. WebAssembly also supports non-web embeddings.

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.

ApplicationPoolIdentity

ApplicationPoolIdentity

ApplicationPoolIdentity is actually the best practice to use in IIS7. It is a dynamically created, unprivelaged account. To add file system security for a particular application pool see IIS.net's "Application Pool Identities". The quick version:
If you application pool is named "DefaultAppPool" (just replace this text below if it is named differently)

1. Open Windows Explorer
2. Select a file or directory.
3. Right click the file and select "Properties"
4. Select the "Security" tab
5. Click the "Edit" and then "Add" button
6. Click the "Locations" button and make sure you select the local machine. (Not the Windows domain if the server belongs to one.)
7. Enter "IIS AppPool\DefaultAppPool" in the "Enter the object names to select:" text box. (Don't forget to change "DefaultAppPool" here to whatever you named your application pool.)
8. Click the "Check Names" button and click "OK".

Oculus Rift

Oculus Rift

The Rift is a virtual reality head-mounted display developed by Oculus VR. It was initially proposed in a Kickstarter campaign, during which Oculus VR (at the time an independent company) raised US$2.5 million for the development of the product.^[5]
The Rift is scheduled for release in the first quarter of 2016, making it one of the first consumer-targeted virtual reality headsets. Oculus has described it as "the first really professional PC-based VR headset".^[4] It has a resolution of 1080×1200 per eye, a 90 Hz refresh rate, and a wide field of view.^[3] It has integrated headphones which provide spatialised audio. The Rift has rotational and positional tracking. The positional tracking is performed by a USB stationary IR sensor, which normally sits on the user's desk, allowing for using the Rift while sitting, standing, or walking around the same room.^[6] .... read more here:https://en.wikipedia.org/wiki/Oculus_Rift
