Utkarsh - The Contragravity

The World Once Laughed at North Korean Cyberpower.  No More. North Korea is country that believes peace can only be made when the enemy surrenders. In recent years North Korea has grown to be the most feared nation, not only in nuclear attacks but cyber warfare as well. Here’s a look at some of the biggest attacks put forth by North Korean agencies on the world. WannaCry On May 12, 2017, organizations across the world reported ransomware infections affecting their computer systems. The infections, caused by a ransomware strain referred to as WannaCry, restrict users' access to a computer until a ransom is paid to unlock it. Reportedly, 300,000 users in at least 150 countries were affected by the ransomware. In April 2017, an anonymous online group known as the Shadow Brokers released what it alleged was a series of surveillance-enabling tools stolen from the National Security Agency (NSA) that, among other things, exploited a Microsoft Windows security vulner...

IBM scientists have successfully made a new world record by storing 330 terabytes of data on a single magnetic tape. 330 terabytes of data are equivalent to the data stored by almost 330 million books. The record is of storing 221 gigabits per square inch which are almost 20 times more data density as stored by currently used devices. In earlier times, to store megabytes of data drum like space was required. Today the technology of compressed data has evolved to such an extent that the data could be stored on a magnetic tape. This tape would fit with the length of our palm. This tape has punches that increase its data density up to 20 times more than the devices used today. This punch card magnetic slip is re-writable. This invention would probably give a thousand-fold increase in the data storage density. In this nanotechnology, holes are drilled in a plastic which has 10 nanometers of spacing. This tape has punches that increase its data density up to 20 times more than the d...

Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture , curate, manage, and process data within a tolerable elapsed time. The term has been in use since the 1990s, with some giving credit to John Mashey for coining or at least making it popular. CHARACTERSTICS: Volume: big data doesn't sample; it just observes and tracks what happens Velocity: big data is often available in real-time Variety: big data draws from text, images, audio, video; plus it completes missing pieces through data fusion Machine Learning: big data often doesn't ask why and simply detects patterns Digital Footprint: big data is often a cost-free byproduct of digital interaction BIG DATA Vs. BUSINESS INTELLIGENCE: Business Intelligence uses descriptive statistics with data with high information density to measure things, detect trends, etc.. Big data uses inductive stats. and concepts from non-linear system identification to inf...

The term   virtual reality   is commonly used by the popular media to describe imaginary worlds that only exist in computers and our minds.   Virtual   is defined to be   being in essence or effect but not in fact .    Reality   is defined to be   something that constitutes a real or actual thing as distinguished from something that is merely apparent; something that exists independently of ideas conceiving it.   Virtual reality is based upon a complete simulation of a real world environment which the user can explore and interact with by means of a head mounted display (HMD) and input device, e.g. data glove. The user loses or immerses themselves in this environment. While instead of replacing reality, augmented reality adds cues onto the already existing real world.  Computer graphics are embedded into the real world and ideally the human mind would not be able to tell the difference between computer-generated images and the r...

Ionic   is a complete open-source Software Development Kit for hybrid mobile app development. Built on top of AngularJS and Apache Cordova,   Ionic   provides tools and services for developing hybrid mobile apps using Web technologies like CSS, HTML5, and Sass. Ionic was created by Max Lynch, Ben Sperry, and Adam Bradley of Drifty Co. in 2013. After releasing an alpha version of the framework in November 2013, a 1.0 beta was released in March 2014, with a 1.0 final in May 2015. Need For Ionic With Ionic, we wanted to build an HTML5 mobile development framework that was focused on   native   or hybrid apps instead of mobile websites. So Ionic apps aren’t meant to be run in a mobile browser app like Chrome or Safari, but rather the low-level browser shell like IOS’s UIWebView or Android’s Web View, which are wrapped by tools like Cordova/Phone Gap. Services and Features Ionic provides all the functionality that can be found in nativ...

How do you remember importan t things that you think you might forget? Some rely on their brain to memorize information while oth ers prefer writing things down on post-it notes. There are ton of digital note-taking apps – from  Evernote  to  Trello  – that can also help you remember anything with ease. There’s another interesting option from Google that you may wish to explore for remembering things. It’s called  Google Assistant , the voice assistant app that is now available on newer Android phones. If you don’t have one, you can still use Google assistant inside the  Google Allo  app that is available for both iPhone and Android. To get started, say “ OK Google ” to launch Google Assistant on your phone and then say “ Remember  ... ” followed by information you would like Google to remember. For instance, you could say: ·       ...

Today 100% anonymity can't be achieved and so does the privacy. But to some extent it can be maintained a lot and VPN is the solution. VPN stands for Virtual Private Network. If you google about VPN then here's what Wikipedia defines it as:"A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across the VPN may therefore benefit from the functionality, security, and management of the private network."  As the name suggests; Virtual Private Network, it is a virtual network inside a network, just for saying. For example, you are connected to the Internet via a network, be it an ISP(Internet Service Provider), Wifi or wireless, your mobile data or some other way round. When you are connected to the network, it is public and anyone can know what...
