A new programming Language Introduced by Facebook - { hack }

Facebook has just released [ Introduced ]  a new programming language called 'HACK', designed to build complex websites and other software quickly and without many flaws and also the main motive of decreasing resource conservation. The company has already migrated almost all of its PHP-based social networking site to HACK over the last year, but it has nothing to do with Hacking.

Facebook :- 
Today we're releasing Hack, a programming language we developed for HHVM that interoperates seamlessly with PHP. Hack reconciles the fast development cycle of PHP with the discipline provided by static typing, while adding many features commonly found in other modern programming languages.
We have deployed Hack at Facebook and it has been a great success. Over the last year, we have migrated nearly our entire PHP codebase to Hack, thanks to both organic adoption and a number of homegrown refactoring tools.
We're also proud to release an open source version of Hack to the public at http://hacklang.org/ as part of our HHVM runtime platform, which will now support both Hack and PHP.

Official site :- http://hacklang.org/

Thus, Hack was born! Facebook Team decides to develop a new programming language that could combine elements of static-type programming languages such as C or C++ with dynamic-type languages like PHP, now called "HACK Programming Language".

"Hack has deep roots in PHP. In fact, most PHP files are already valid Hack files." Facebook said, "We have also added many new features that we believe will help make developers more productive."

HACK is a new version of PHP, requires Facebook’s HHVM (Hip Hop Virtual Machine) which is designed to execute programs written in Hack and PHP. The top 20 open source frameworks on Github run on HHVM.

by Facebook's - { hack } official site  :- 
The following are some of the important language features of Hack. For more information, see the full documentation, or follow through the quick interactive tutorial.
  • Type Annotations allow for PHP code to be explicitly typed on parameters, class member variables and return values:
class MyClass {
const int MyConst = 0;
private string $x = '';
public function increment(int $x): int {
$y = $x + 1;
return $y;
  • Generics allow classes and methods to be parameterized (i.e., a type associated when a class is instantiated or a method is called) in the same vein as statically type languages like C# and Java):
class Box<T> {
protected T $data;
public function __construct(T $data) {
$this->data = $data;
public function getData(): T {
return $this->data;
  • Nullable Types are supported by Hack through use of the ? operator. This introduces a safer way to deal with nulls and is very useful for primitive types that don’t generally allow null as one of their values, such as bool and int (using ?bool and ?intrespectively). The operator can be used on any type or class.
  • Collections enhance the experience of working with PHP arrays, by providing first class, built-in parameterized types such as Vector (an ordered, index-based list), Map(an ordered dictionary), Set (a list of unique values), and Pair (an index-based collection of exactly two elements).
  • Lambdas offer similar functionality to PHP closures, but they capture variables from the enclosing function body implicitly and are less verbose:
function foo(): (function(string): string) {
$x = 'bar';
return $y ==> $x . $y;
function test(): void {
$fn = foo();
echo $fn('baz'); // barbaz
Other significant features of Hack include ShapesType AliasingAsync support, andmuch more

Download Beta VLC Player for Winodws - 8 & Windows 8 RT

VLC now available for Windows 8 one of the best multimedia players has finally come to Windows 8 and Windows 8 RT. A few hours ago that they have posted on the official blog announcing a beta version, but perfectly functional.

VLC for Windows 8 development has been paid thanks to a round of funding on Kickstarter that got nearly $80,000. The application is tailored to the interface ModernUI that characterized the new generation of Windows and can be downloaded directly from the app store.

The usual VLC in other systems notice less fluid than usual operation and some minor problems to work with subtitles, while taking into account that we are talking about a beta, developers work is more than notable. A year later, Windows 8 users can now enjoy great VLC. this is given in VLC's one of the blogpost

Today, the first Beta of VLC for WinRT is getting deployed on the store.
As many of you know, the road to come to this point has been long... Very long.
I've been driving or helping some ports of VLC on mobile, but this port has been the hardest, by an order of magnitude.
I'll speak a bit more about the lateness of this port, another time. Today, I'll introduce a bit to this application.


This application, version 0.2.0, is a BETA stage of the port of libVLC on WinRT. WinRT is the runtime of Windows 8/8.1 Metro/ModernUI, Windows Phone 8 and Xbox 1.
As this is a beta, some features are still not perfectly stable, but we are working on that. We thought we should share it with the users, so that people could test and help us.
This application:
  • works on Windows 8.0 and 8.1: too many people are still on 8.0, so we had to use that. This decreases the stability of the application, though...
  • is compiled for Intel x86 CPUs: Windows RT version will follow as soon as we are able to compile it. ARM version will also apply to Windows Phone.
  • plays all video and audio formats of VLC, including MKV, Ogg and Mov files or FLAC and MPC;
  • supports the same codecs as the VLC application for desktop, from MPEG-1 to H.265, through WMV3 and VC-1;
  • supports multiple-audio tracks selection;
  • supports embedded subtitles;
  • supports Background Audio playback;
  • features a easy-to-navigate but complete UI, notably for audio browsing;
  • supports Live Tiles!
  • supports removable storage and DLNA servers.
However, there are a few limitations:
  • This app is currently slow, and is slower than VLC for desktop for video decoding and has no hardware acceleration;
  • Subtitles support is not very good yet, and notably it only supports embedded subtitles; this is our major point of focus for now.
  • Audio does not seem to work in all configurations;
  • Playlists and streams are not supported in the UI (they are present in the core)
  • It's clearly not as stable as it should be.
We are working on all those points, but notably on subtitles and audio quality and stability. Since we now have a release, it will be easier to do releases quite often, as soon as we can.
We also have longer terms goal to work on, and we'll share them when we know more :)
We hope you like this application, and if you don't, we'll fix that soon :)

Micromax Canvas Knight A350 review: Octa-core phone for Rs 19,999

First things first. This is a phone from Micromax, but it does not look like a phone from Micromax. In fact, it looks like a phone from a well-heeled international brand, the sort that Micromax wants to become in the near future. This is the Micromax Canvas Knight, the phone that will take over the flagship mantle for the company from today.
Quick Tech Specs: 5-inch IPS display (1920×1080 pixels, 443 ppi) | 2GHz Tru Octa core MediaTek MT MT 6592 processor | 2GB RAM | 32 GB storage + no microSD slot | 16MP rear camera, 8MP front camera, 1080p Full HD video | 3G, Wi-Fi 802.11 b/g/n, Bluetooth 4.0 | 2350mAh battery | Android 4.2 JellyBean
Price: Rs 19,999

Design: As I said this phone does not look like a Indian phone. In fact, it has the cuts and sides of the Apple iPhone 5s and even reminded me a bit of the Lava Iris Pro 30, which also had a similar design language. The unibody design is reinforced by what seems, and feels, like a graphite frame. There are mico-SIM slots on both sides that can be accessed by a pin. And, no there is no space for a SD card. Another thing that sets this phone apart is the power key, that is now placed along with the volume keys on the right. This take a bit of getting used to.

The camera, the 16 MP sensor that it houses, results in a significant bump on the rear and there is an extra rear cover to sort of protect it. This feature is a bit like the one on the Nokia Lumia 502 and it becoming common in slim phones with large cameras. The phone is very light and easy to handle despite the large screen.
Screen & Audio: The Full HD IPS panel is one of the best features of this phone. To start with, there is hardly any light bleed on the sides. The phone can be bright enough to be legible in bright sunlight. The audio quality is good, but not great. The overall experience, however, is quite good.
Performance: This is a Tru Octa core phone. So performance should not be, and is not, and issue at all. In fact, the Antutu benchmark scored it in the top draw and exclaimed ‘amazing’. Yes, that doesn’t mean much for an average used. What matter for him is the fact that there is no lag anywhere and that multi-tasking is a breeze. We tried multi-tabbed browsing on Chrome and the experience was superb. However, with some games we noticed that the device did heat
Micromax has officially launched the Canvas Knight Smartphone in India for Rs 19,999. The company launched this device first in Russia while it launched its operations there. Micromax Canvas Knight is the company’s first Octa-Core smartphone and also the first to have 16-MegaPixel camera on board. This device comes with a powerful 2GHz Octa-Core MediaTek processor coupled with 2GB of RAM.
This smartphone is the most advanced and the best one from Micromax till now. The design of the device looks inspired from iPhone 5 but what it does different is have different layout and larger screen. It sports a 5-inch multi touch HD display with a resolution of 1920x1080 pixels with an amazing pixel density of 443 pixels per inch.
This smartphone come with Android 4.2.2 Jelly Bean Operating System and is expected to get Android KitKat Update soon. Other features of the phones include a 16-MegPixel camera on the rear side with LED flash and Autofocus for photography and a 5-MP front facing camera for Video calling. This smartphone uses a 2,350mAH battery for the power supply. Previously the company launched the Canvas Turbo and Canvas Turbo Minismartphone with amazing price and features.

Google’s Project Ara of a Modular Smartphone Could Start at $50

Last year, designer Dave Hakkens positioned the concept of a modular smartphone--or Phonebloks--as a way to cut down on the electronic waste of handsets. Motorola would go on to work with Phonebloks to eventually bring the idea to fruition, with the end result being Google's Project Ara. And according to a report from Time, these customizable phones could be out next year for an incredibly affordable price point.

"The smartphone is one of the most empowering and intimate objects in our lives," said Paul Eremenko, who heads up Project Ara for Google ATAP. "Yet most of us have little say in how the device is made, what it does, and how it looks." Interestingly, the Advanced Technology and Projects (ATAP) group was one sector Google kept following the sale of Motorola to Lenovo.
Google thinks Project Ara could offer an entry point into the smartphone market for emerging regions, citing the over five billion people in the world who are still without one. According to the Time report, Google wants Ara smartphones on the market by 2015, for as little as $50.
On January 29, Google announced that it had agreed to sell Motorola, its phone-manufacturing business, to Chinese electronics giant Lenovo. Thus concluded the company’s brief, unprofitable foray into smartphone hardware, which began when it revealed plans to acquire Motorola Mobility in August, 2011.
Granted, the $50 handset will only have base features--perhaps even lacking cellular functionality--but it's still an interesting starting point. Since users could swap out the modules for better features at whim, Ara has the potential to be a fully customizable, truly affordable smartphone.

The current plans call for three different sizes of modular smartphones, from the $50 mini up to a large phablet. And given the opportunity for unique modules, there's no telling what developers may dream up. Google will host a series of developer conferences for Ara, beginning in April. But anyone can check the devices out, thanks to a free live-stream.

Except that it didn’t really end there. It turned out that Google was holding onto one organization within Motorola: the Advanced Technology and Projects (ATAP) group. Headed by Regina Dugan, the former director of the U.S. Defense Department’s fabled Defense Advanced Research Projects Agency (DARPA), ATAP aims to bring the same approach to mobile-gadget innovation that DARPA used to kickstart the Internet, satellite navigation, stealth fighters and other technologies that started small and eventually mattered a lot.
In retrospect, it’s completely logical that Google would choose to retain ATAP. The technologies and projects it specializes in are the wildly audacious ideas Google likes to call moonshots. The company already has another group devoted to such efforts — Google X, which is working on Google Glass, self-driving cars, broadband balloons and more — but it’s hard to imagine it handing off any moonshots in progress to Lenovo or anyone else.
Among the ATAP initiatives that have been announced, one in particular is quintessentially Google-y. It’s Project Ara, which aims to reinvent the smartphone by breaking it down into modules that can be assembled and customized in a limitless number of configurations. The company first disclosed that the project existed on October 29 of last year, when it released some intriguing photos but little in the way of concrete details. Today, it’s lifting the veil further as it prepares for an Ara developer conference it’s holding at Silicon Valley’s Computer History Museum on April 15-16. A year or so from now, it hopes to have a product on the market.
