News: Mimesys Combines Mixed & Virtual Reality Holoportation Capabilities into One Solution

Mimesys, whose core focus has always been about creating holographic representations of humans for virtual and augmented reality, has released a video showing off their holographic communication platform in action. This new communication tool uses a combination of virtual reality, with the HTC Vive and a Kinect, and mixed reality, with the HoloLens, to allow the users to have virtual meetings from anywhere in the world as though they are in the same room.

How To: Make Your Android's Screen Stay On in Certain Apps

The default screen timeout on most Android devices is 30 seconds. This usually offers a good balance of usability and battery savings, but sometimes, you need the screen to stay on longer. For instance, practically every time I try to show something on my phone to someone else, the screen locks before they get a chance to see it. But increasing the system-wide screen timeout isn't a great solution either, because this can lead to unnecessary battery drain and even screen burn-in.

Exclusive: Dual-Boot Android on Your iPhone (iOS 7+)

Today we are pleased to announce the end to the Apple vs. Android war. About a year ago, our Gadget Hacks team started working on a top-secret project to dual-boot both Android and iOS on the same phone—and we couldn't be more proud to announce that we've finally succeeded! Your phone can now run both iOS and Android—whenever you want. Right now.

Brought to you by Tomcat. Falling snow, warm fireplace, delicious hot cocoa, quiet reading time, mouse. Quick quiz - which one is not like the other? Nothing can ruin a perfectly cozy afternoon in your home like a pest on the loose. With dropping temperatures, you may have some unwelcome residents, like mice, looking for shelter from the cold.

News: Google Releases "Dogfood" YouTube App to Google Play

If you watched a YouTube video on your Android device today, you may may noticed something just a little different. If you haven't, go check out the app in your drawer or homepage. Google today pushed out an update to their YouTube app, but by all accounts, it was never meant to hit the public. This is labeled a dogfood build, which is a term used to describe products going through in-house testing, in effect "eating their own dogfood".

News: Hackers Can Remotely Set HP Printers on Fire: Is Yours Vulnerable?

Do you own an HP printer? If so, it may be vulnerable to malware attacks. Researchers at Columbia University discovered that 25% of Hewlett-Packard printers have significant vulnerabilities that put your printer in danger from hackers—even your home. With a budget of just $2,000, researchers Salvatore Stolfo and Ang Cui were able to hack into the printers using remote firmware to install malware, and in some cases even cause the printer to catch on fire. The main issue is with the printer's c...

How To: Write a literature review for thesis writers

In this tutorial, we learn how to write a literature review for thesis writers. The three elements are: discuss the most relevant theory, introduce and define key terms, and discuss recent research in the field. You will need to include the most important literature, quote directly only if you discuss at some length, and use indirect quotes as well. Focus on notions you will use in your empirical study. It should be ten pages or less and sources of all quotes must appear in your works cited p...

How To: Understand completing the square

In this video, we learn how to understand completing the square. First, you will write the quadratic expression out. Then, you will write the open bracket so you write it out in the correct format. Now, find the number in front of the 'x' term, which is the coefficient. Then, write this number on the other side of the equation in the parenthesis. From here, you will need to follow the proper rules of math to find out what the square is equal to. When you are finished, make sure you label the ...

How To: Understand negative exponents

In this video, we learn how to understand negative exponents. The one rule you have to remember is when you have a number with a negative power, then you need to divide it over one. You can take this term and put it in the denominator of your fraction to make it a positive exponent. For example, if you have 5 to the -1, then you can move the 5 to the denominator and get 1/5, which is the same exact thing! This is one of the most basic rules in math. Once you understand this, simplifying fract...

How To: Calculate a limit at infinity with a radical

In this video, we learn how to calculate a limit at infinity with a radical. The idea is to take out the higher power of 'x' in the denominator first. If the x squared is under a radical, take that out so you're left with just 'x'. After this, divide every term by 'x'. Once you are finished with this, you can rewrite the equation. Next, you will use the rules of math to find the answer of the equation. This is hard math to do if you aren't used to it! Make sure you practice with the samples i...

How To: Describe chemical formulas

This is a video tutorial in the Education category where you are going to learn how to describe chemical formulas. A chemical formula represents the actual number of atoms of each element within a molecule. Different visual representations of molecules include the ball and stick three dimensional model, a line drawing that represents the structure in two dimensional terms, and a shorthand used by organic chemists. If a molecule has 4 green atoms and 2 orange atoms, the ratio of green to orang...

How To: Find the interior & exterior angles of a triangle

In this tutorial, we learn how to find the interior and exterior angles of a triangle. I triangle has three angles and their measurement when added together will equal 180. For example, if one angle is 80 and another is 30, then start off saying the equation equals 180. Write in 80+30+X in front of the equals sign, then subtract the combined like terms from the 180. After this, you will have found the value of x, which will also be the measurement of the last angle. Make sure to write out the...

How To: Understand fractional exponents

In this tutorial, we learn how to understand fractional exponents. Starting with an example, let's say you have the square root of four as an equation. The answer to this is two. A fractional exponent is not much different than this problem. Let's say you have 4 to the 1/2 power. This would be equal to (2 squared) 1/2. Now, using the third exponent law, the term becomes 2 to the power of two x 1/2. This will leave you with the answer of two. Now you know how to get the correct answer and can ...

How To: Find abc, curve direction & y-intercept (quadratic eq)

In this tutorial, we learn how to find abc, curve direction & y-intercept (quadratic eq). First, you need to find the a,b, and c of the equation. A will equal what the coefficient is in the equation, B will equal the second, and C will equal the third term. This tells us if the numbers are positive or negative, so so know if the parabola opens up or down. To graph C, you will know what the y-intercept is going to be, then find the matching units. After this, you will use B to shape the parabo...
