The Giving Plant: Same Asian Plant Used for Arthritis Treatment Gives Us Powerful HIV Drug

Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.

How To: OSX VM Image Install Guide

I was on our new #nullbyte IRC channel when someone told me how tedious it is to install an OSX Virtual Machine on Virtual Box (I think it was wawa). We all know Linux rocks (gets acknowledgement from the crowd), but there are morons out there, multiplying at a never before seen rate, who use OSX. We at nullbyte should be prepared for anything and everything. So, in this guide I take you step by step to creating your OSX Yogemite VM.

Behind the Hack: How I Discovered the 8-Try Master Combo Lock Exploit

In my last guide, I showed how you could crack the combination of any Master Lock combination padlock in 8 tries or less using my online calculator. Now, as promised, I'll be showing you how I devised the attack, which is based off the well-known technique that reduces the 64,000 possible combinations of a Master Lock down to just 100. Here, I will be drilling open a Master combo lock to show you how the insides work.

How To: Make a Super-Simple Steampunk iPad Case Out of Leather

I chose to make this a Steampunk iPad case, but you can change the details and make it look as modern as you'd like. As I said earlier, Steampunks probably shouldn't buy iPhones or iPads, but if you're going to get one, you may as well make it look cool, right? The iPad pictured below was borrowed from a friend of mine, though I should add that this design will easily work with tablet computers of any variety, Apple, Android, or otherwise.

How To: Generate Private Encryption Keys with the Diffie-Hellman Key Exchange

When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.

How To: Everything You Should Know About Rolling Shutter on Your Phone's Camera

Smartphone videos get better and better each year. Seven or eight years ago, who would have thought iPhone and Android phones could support 4K video recording. Some phones can even shoot slow-motion at 960 fps. But no matter the resolution or frame rate, a phone's rolling shutter can make quick movements in front of the camera appear wobbly, distorted, or with artifacts.

How To: Find the area of a rectangle using geometry

This video shows how to compute the area of a rectangle given the length of one of its sides and its diagonal. First start by drawing the picture of the rectangle. Now draw the diagonal and label the known lengths. In the diagram, the diagonal and two sides of the rectangle form a right-angled triangle. The breadth of the rectangle can be computed using the Pythagorean theorem. Finally, compute the area of the rectangle by multiplying its length to its breadth.

How To: Change percents into fractions

Fractions are numbers written in the form a/b, where a, b are integers. Fractions can also be expressed in the form of percents by multiplying the value of the fraction with hundred. So we can always change percents to fractions and also fractions to percents. Remember that percent means hundredth. So percent means a fraction with a denominator of hundred. When you are given percents and asked to calculate its fraction, divide the percent with hundred. Now this fraction can be further reduced...

How To: Dimensional Analysis

What Is Dimensional Analysis? Dimensional analysis is used to convert units. It's the process of analyzing units to decide which conversion factor to use. It's used by multiplying units by conversion factors, rates equal to 1.

How To: Solve Proportions

The Solution The first step to solving proportions is cross multiplying. For example, we are told to solve the proportion 13/3 = x/9. We cross multiply 13 •9 and 3 • x. Remember, the equal sign does not go away, so don't forget about it! The equation is now 3x = 117. We need to isolate the variable so we do 3x ÷ 3, which is x, and 117 ÷ 3, which equals 39. We now know that x = 39. Practice Time
