Why Apple made antivirus iOS apps unavailable


In March 2015, Apple cracked down on antivirus apps, pulling a huge number of them from the App Store. Many believe the reason behind this move is to eliminate concerns about whether or not iOS devices are susceptible to virus and malware attacks.

One of the apps removed from the App Store indicated it was a virus barrier. Apple informed them that the app’s description was “misleading” and could potentially lead customers to believe that viruses are present in iOS.

Why is Apple so confident in their ability to protect against vulnerabilities?

Google-owned Boston Dynamic’s Robo-Dog is Amazing!


Have you ever watched one of those “smartphone drop test” videos on YouTube? Robots that move around are essentially like these smartphones, too – impact caused by a fall can cause major damage to their components or motors.

That’s why developers are creating measures to ensure robots stay intact in case they suffer a nasty fall. Two researchers from Georgia Tech have come up with an algorithm that instantly sends information to robots, so they can correct themselves and brace for impact as soon as they lose their balance.

They indicate when you fall down, you try to dissipate energy. And every time you make contact with the ground, some of that energy is dissipated.

According to the researchers, the key to protecting the robot’s internal components is to make it go limp instead of tensing up to prepare for impact. They plan to expand the algorithm further, to ensure the robot avoids falling on a person.

BigDog and Spot

The algorithm created by the Georgia Tech researchers is very similar to the one built into BigDog and Spot, two robot dogs created by researchers from Google-owned Boston Dynamics.

MIT UAV drone achieves autonomous flight


Drones have entered a new level of advancement. The Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has successfully developed a system that lets drones detect obstacles in their flight path and therefore avoid them.

In test flights, this has allowed the drone to fly autonomously through trees and an open field at speeds of more than 30 miles an hour (48 kph). And this was achieved using only a pair of cameras and two processors no more powerful than the ones being used in a smartphone. Check out the video below to see it in action.

What is the dark web (aka deep web, deepnet, hidden web, invisible web, undernet)?


Many of you have likely heard the terms dark web, deep web, deepnet, hidden web, invisible web, or undernet in some of your discussions, books, or even movies. This is another layer of World Wide Web (WWW) content that exists on these darknets which is overlayed using the public Internet however you require specific software and configurations to access. This hidden content is not considered part of the surface web we all use on a daily basis. Big search engines like Google or Bing do not crawl and index this darknet content.

One of the most well-known underground sites was the anonymous narcotics bazaar called the Silk Road. It had been running for 2.5 years until the FBI shut it down in the fall of 2013. When they seized the website, they also got $4 million in bitcoins which was the cryptocurrency being used to buy drugs on the Silk Road. The Silk Road generated an estimated $1.2 billion in revenues since its creation.

How do you access the dark web?

The invisibility cloak is in our future


We’ve all fantasized about being able to turn invisible. And maybe having an invisible cloak à la Harry Potter. Well, it looks like some people are actually trying to turn that fantasy into reality.

Though we are still decades away from being able to hang up an actual invisibility cloak in our closets, researchers at the Pennsylvania State University have come close to creating something amazingly similar. A team of scientists have formulated a concealing screen made of material only 80 nanometers thick – that’s a thousand times thinner than actual human hair!

Small land-based robots to be used for deliveries


Most of us have heard about Amazon’s plans to use aerial drones to make deliveries. Starship Technologies, a company built by two of Skype’s cofounders believes that concept isn’t really practical – they believe using self-driving earthbound drones is a safer, cheaper, and way better solution.

Their delivery bots are CO2 emission-free, and are capable of delivering groceries and small packages weighing up to 40 pounds. The packages will be safe and secure inside the robots, as they are designed to be very difficult to break into.
