WonderHowTo is made up of niche communities called Worlds. If you've yet to join one (or create your own), get a taste below of what's going on in the community. Check in every Wednesday for a roundup of new activities and projects.
Welcome to Math Craft World! This community is dedicated to the exploration of mathematically inspired art and architecture through projects, community submissions, and inspirational posts related to the topic at hand. Every week, there will be approximately four posts according to the following schedule:
Welcome to the Google+ Insider's Guide to all things Google+. We're dedicated to keeping you updated with all the latest news, tips and tricks on Google+, and this official index will serve as a one-stop catalog of all our How-To articles, as well as all the news & updates we've covered over time.
Making your way into an online community can be really exciting. Some life-long friendships and lasting romances begin in humble chat rooms and message boards. But for the novice internet user, one of the biggest hurdles can be trying to figure out just what people are saying to one another.
The CNA certification exam can be stressful at times, especially on the clinical exam portion. However, despite the exam difficulties, everything has a solution. Qualified nursing assistants are preparing various CNA study techniques and CNA study guides just to reduce any test anxieties and stress.
Business owners and marketeers are diverting from traditional marketing techniques, including billboards, radio and TV advertising, brochures, and any other outdoor promotions, to cheaper but effective Internet marketing strategies. Under the new arrangement, business owners reach out to the final consumers through advertising on the World Wide Web.
Pranks are fun, but finding a way to maximize the affect of a prank can be tricky. Toilet papering the whole campus or repainting all of the parking spaces slightly smaller can take a long time and a lot of resources. A better plan of attack is to booby trap the choke points where your victims are forced to pass through. Think like a guerrilla. A dorm doorway is a good idea.
Today's fancy cars come with all sorts of options, from power mirrors to working seat belts. Some of us condemned to live in the reality of capitalist recession have no car, or perhaps a very modest one. But your modest car can still have some cutting edge technology wedged into the trunk and dashboard if you know what you want and where to look for parts. Today, we make a parking sensor using a sonic range finder, just like in the vehicles our owners drive!
If there ever was a time for Null Byte to need people to contribute, it's now. Let's make Null Byte a place where anyone, from novice to master computer user, come and learn. It has been sometime since the last "Call to Arms" for Null Byte, and even longer since the last "Weekend Homework". We all know that this time of year is busy for everyone, but that didn't stop occupytheweb otw from creating a great article in his continuing "Hack Like a Pro" series.
To create an elegant WordPress blog or website from scratch without being noticed that you're a complete beginner, you need that drive and pairs of eyes and ears. It may seem difficult at first but it can truly be fun and exciting.
Hobby rockets are tons of fun. Vicarious astronaut adventures abound with every launch. What if you want to be closer to the action though? What if you want to feel what it's like to be in a rocket at takeoff? With the discovery of tiny keychain cameras, we have technology small and cheap enough to fit inside a model rocket!
Another week has passed on the online battlefield as the CISPA legislation continues to grind away at our freedom. Here at Null Byte, we try to keep our community informed and knowledgeable at the same time—and that means creating content for them to learn from.
Lying is awesome. From a very young age, children learn that flat out denying the truth gets you out of trouble and helps keep you calm in the face of horror. But what happens when you just have to know if someone, say, used your toothbrush? You could ask them to take an expensive and arduous polygraph test.
When I was attending college, my friends had a phantom thief in their dormitory. Almost every night, a different item of food would go missing, never to be seen again. There was constant speculation as to whom the thief was and how to catch them. Security cameras were deemed too invasive, but none could think of another method of surveillance... until today.
Bikes are a great form of transportation. They use human energy more efficiently than any other machine. You can keep it in your closet or hallway. You can even take it on the train in a pinch. However, this portability is also the bike's biggest draw back. If you own a bike in the city, chances are it will be stolen. Locks barely deter thieves armed with bolt cutters and crowbars. Throw the bike thieves for a loop and make a tilt-sensitive alarm. It will hopefully startle your bike's assaila...
House plants are a refreshing reminder of the rich biosphere teaming with life just outside of our hermetically sealed human dens. They calm us and clean our air. But what would you do if you came across a glowing green flower on your dinner table? I would be startled, but not shaken.
Rockets are lots of fun when you are launching them. However, finding them can be an arduous if not maddening task. Fancy space rockets have lots of tracking equipment to make touchdowns as simple as pie. Today, we look at embedding LEDs into your hobby rocket for easy night flight fun!
Since the rise of private property and industrial production, modern capitalism has been on a undeniable crash course with Mother Nature. It's no so much that we'll end up murdering the entire planet, but just that the planet will quietly smother us with a pillow of famine, heat, cold and hurricanes. We over-farm land and replace the nutrients in the soil with oil. To package our oil-based produce, we wrap them in synthetic oil-based plastics, soon to be discarded in a trash heap or ocean.
The only thing better than successfully pulling off a new experiment is doing it with household materials. You get to laugh in conceit as professional scientists everywhere spend all their grant money on the same project you just accomplished with some under-the-sink chemicals! However, there are times when DIY gets dangerous. Some household chemicals are not pure enough to use and some are just pure dangerous. Let's take a look at two problems I have encountered in the course of mad sciencing.
Glass is one of the least reactive substances known to chemistry. It is the standard container material for almost all lab chemicals because it's so inert. But there are a couple of substances that have strong reactions with glass. Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away! So, the next time you clog up your drains with broken glass beakers and flasks, rest assur...
You're never too young to start building your vast swarm of robotic minions. Taking over the world requires a whole lot of robots. The sheer volume of robots needed means your first wave will have to be made of cheap materials. After they take over key resources, you can upgrade to Kevlar and titanium. But to start, let's make popsicle stick insect robots!
Science-fiction writer Jules Verne predicted many scientific breakthroughs, including the moon landing, tasers, and nuclear submarines. In his 1874 book The Mysterious Island, Verne writes:
Around the world, X-People (yes... there are X-Women, too) are under attack from an intolerant sapiencentric ruling class. Integration without equality is a farce. Autonomy is denied outright. Human prejudice cannot abide a mutant state. Human fear, born to hate, imposes itself on the life of every mutant.
If you've read my darknet series, you've probably got a pretty good idea of what I2P actually is and is capable of. One of the features of I2P is that it's designed with P2P file sharing in mind. Using a built-in service called I2PSnark, you can host and seed torrents quickly and easily!
Everyone dreams of having super powers. Flying, invisibility, and x-ray vision are popular, but my favorite is fire power! I've always wanted to be Wheeler from the Captain Planet kids show, and now I can with these handheld fireballs of awesomeness. The fireballs burn at a low temperature, so they are safe to hold in your hand and throw (shoot) at imaginary enemies.
Here at Null Byte, we try to inform and teach the community on ways to navigate the Internet in that special way, as well as staying safe along the trip. That being said, I need some help from all of you! There is a lot of information to cover and I know we have some smart users lurking around. We would love to hear from you.
Taking apart batteries is one of those things that every adult you've ever known has warned you against. Today, we break the taboo and dive into a lithium battery. Lithium has some pretty cool properties—it burns instantly in water and glows blindly bright under flame. And with just one AA battery, you can make a blinding light beam inspiring supernatural awe in all dictatorial adults who doubted you.
Writing secret notes with lemon juice was one of my favorite pastimes as a child. All it took was a small flame to lightly scorch the paper and reveal the hidden message. Now that I'm tall and pay bills, lemon ink just isn't exciting enough anymore. Luckily, we can use another kind of invisible ink to write in fire! By using the saltpeter, we can whip up invisible fire ink in no time.
Last time, we looked at archaic cryptography, so you should have a basic understanding of some of the concepts and terminology you'll need. Now, we'll discuss one of the most important advances in computer security in the 20th century—public key cryptography.
Last week, we had a great contribution from Christopher Voute, who introduced us all on some of the basic moves in Python. Now, who else will share their knowledge and tackle some of the topics below?
Did you know there is hidden data in your digital pictures? Well, there is, and that data might be a security risk to you. Think back at all of those pictures you're in and are connected with. I'm sure some of those you'd like to distance yourself from. And surely you wouldn't mind checking out the metadata in a few of those images. In this article, we'll be going over how to do just that.
There is a vast amount of knowledge out there on computers! In fact, it is so vast that no single person could ever possibly ever learn everything there is to learn about hacking or computers in general. People usually specialize in a certain field: cryptography, computer security, networking, software development, testing, and so on...It's probably a bit premature to decide what you want your speciality to be, but keeping the question in the back of your mind will help give you direction in ...
Jet engines combine oxygen from the surrounding air with on-board fuel to burn at very high temperatures and create thrust in the direction of the flame. Rockets, which we will learn about in a later post, are similar but carry oxygen internally and can therefore function in space!
Cryptography is a quintessential part of computer security in the modern world. Whenever you buy something on eBay or log into Facebook, that data is encrypted before it's sent to the server in order to prevent third parties from eavesdropping and stealing your sensitive information.
I recently posted a link to what seemed to be a very useful guide on Lifehacker for creating a TOR button in Chrome. However, when I tried it myself, it did not work. Also, it lacked a warning on the limits of Tor, which I think are important. Therefore, I decided to create an updated and more comprehensive tutorial.
Are you the expert hacker we're looking for? Do you have a great idea for an article on Null Byte? Do you have a passion to write, and more importantly... teach?
If you're hungry, eat now, because this list is probably going to put you off consuming vittles for so long that you'll end up looking like the love child of Nicole Richie and Skeletor. Now that you've been officially warned, help me count down the ten most WTF food items on this beautiful blue marble we call Earth.
Grab your thinking caps and get your hack on. Null Byte is officially seeking contributors on a weekly basis who are willing to take the time to educate the Null Byte community on anything, from hardware hacks to life hacks. Contributors that write tutorials will be featured on the Null Byte blog, as well as the front page of WonderHowTo (providing it's up to par, of course).
We had a blast during last week's social engineering calls. One of our attending social engineers was so clever that she convinced several people on Craigslist that lost items were hers, even if it seemed she couldn't be trusted. But females are better social engineers, naturally. Some say that females have a special knack for manipulating men, but I think that's preposterous. I can't see why that would be true in a million years (note my sarcasm).
Law enforcement can make a lot of folks cringe. Too often do we hear on the news, and even experience in our own lives, the unjust way that an unacceptable portion of law enforcement treat the very citizens they are supposed to protect. People's rights are violate each and every day by law enforcement, simply because they are timid and uneducated with the laws of society. This dirty trickery shouldn't be played on harmless citizens under any circumstances.
