WonderHowTo is a how-to website made up of niche communities called Worlds, with topics ranging from Minecraft to science experiments to Scrabble and everything in-between. Check in every Wednesday evening for a roundup of user-run activities and how-to projects from the most popular communities. Users can join and participate in any World they're interested in, as well as start their own community.
It was brought up a while back in a Community Call to Arms that *math* is handy for encryption (and let's face it, everything) so let us go over things you just have to know. "In its simplest meaning in mathematics and logic, an operation is an action or procedure which produces a new value from one or more input values."[source]
Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. Luckily, we can whip up our own etchant at home with everyday chemicals! Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride.
Creating any object you want is as simple as point and click if you have a 3D printer at home. If you don't have one handy, there are a few companies that offer printing services online. But to help services realize your design in extruded plastic, you have to make a 3D computer model for the printing machine. For beginners, the free Google SketchUp application is the best choice of software. Using only a few tool bar buttons and a scroll wheel computer mouse, you can model literally any obje...
Graffiti is a great way of getting your message out to the masses. The earliest known graffiti dates back to 30,000 years ago and used the traditional apply-paint-to-wall technique. Though our paint now comes in cans and not from scavenged berries, the actual graffiti process hasn't really evolved from those first cave paintings.
Homemade circuits are amazing. You can build any kind of circuit on a simple perfboard, as we have seen in previous projects. However, some projects require very tiny circuit boards. We could special order some boards from a printed circuit board (PCB) factory, but that will most likely involve a high price per board and a few thousand miles of delivery service to pay for.
You want to put out a live web server, but you don't want to be owned in the process. An expert eye for security is not needed if you take a few basic steps in locking down the hatches. Most successful attacks today are not the complex, time-consuming tasks you might think, but simple lapses in policy that a hacker can take advantage of to compromise your server.
If you're a frequenter of Null Byte, I bet you have at least some interest in information security. Furthermore, you have a hobby that if applied in certain ways, will get you arrested. I've received quite a few messages from the community here about federal cybercrime law and how it applies to them, so I decided to get together with my lawyer to come up with some answers.
Remember that scene in The Matrix when Trinity uses a realistic Nmap port scan, followed by an actual SSH exploit (long since patched) to break into a power company? Well, believe it or not, but that scene is not far fetched at all. If you want to exploit vulnerabilities and root boxes, you'll need to learn how to perform the necessary reconnaissance first. In fact, you will spend far more time researching your target then you will exploiting it. In this article, I am going to show you the fi...
Welcome to Minecraft World! Check out our tutorials, post to the community corkboard, and come play on our free server!
Many windows users, if not all, run into a virus infection once in a while. This is unavoidable when using Microsoft's operating system. Without digressing too much, the fact that Windows is such a popular OS with no controlled software sources makes it easy for viruses and malware to spread. And while there's a plethora of antivirus tools for Windows, sometimes infections (such as certain scareware) can disable the install and/or use of antivirus systems and render your OS unusable until cle...
Amazingly, a lot of people I know haven't even heard of SOPA or PIPA. Now, every English-reading person with an internet connection will finally have those two four-letter acronyms emblazoned in their minds. For the entire day today, Wikipedia's English-language site will be in total blackout in protest against the proposed legislation in the United States. And that's not all. MoveOn, Reddit, BoingBoing, Mozilla, WordPress, TwitPic and other popular websites are down today in protest.
Welcome to Minecraft World! Check out our advanced tutorials and come play on our free server. Part 5 in Minecraft World's Ultimate Survival Guide is, for me, the longest article to write. Since I squeezed out a lot of information from other areas to put into survivability, its going to be a fairly long read. Of course, you can just skip to your topic of choice.
WonderHowTo is made up 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.
It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. I also thought we'd take a look at building a model that has appeared in numerous posts. It's the simplest of the intersecting plane modular origami sculptures: The WXYZ Intersecting Planes model.
Problem: You're a PC gamer who absolutely loves The Elder Scrolls series and were eagerly anticipating the release of the newest game, Skyrim. But as much as you'd like to pick up the new game, money is tight. What do you do?

Welcome to Minecraft World! Check out our advanced tutorials and come play on our free server. While mining is a basic aspect of Minecraft, it is often overlooked. Every adventure requires iron and diamonds and other ore and if you're playing in hardcore mode then you need all the help you can get.
It's Monday, and once again it's time to highlight some of the community submissions posted to the Math Craft corkboard. In addition, I thought we'd take a look at having fun with the geometrical properties of polygons and circles by using one of the best circles I know, the penny.
Last week's challenge brought up a good question (thanks Lisa) regarding the functionality of the Official Scrabble Players Dictionary, 4th Edition, both online and in print form. The word TACTICAL was the answer to the first puzzle in that challenge, but when you search for the word directly in the print version, it can't be found. Likewise, when you search the online dictionary on Hasbro's site, you won't find it either. Go ahead, try it. You won't find it looking for TACTICAL specifically.
It's Monday, time to highlight some of the community submissions posted to the Math Craft corkboard. One of these posts inspired me so much, I think it merits a closer look. Today, I present a "simple" method for making a golden spiral using just a straight edge, a compass, and a template, inspired by RJ Ellicock's golden ratio post.
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:
If you're interested in bypassing Windows and Linux passwords, there is a great tool from the good people at Kryptoslogic. Have you ever forgotten your administrator password? Have you ever bought a used computer with a password on it? Well, Kryptoslogic have created a boot-disc call 'Kon-Boot', which allows you to bypass any Windows 32 or 64 bit OS, as well as Linux passwords. There is both a paid and freeware version available.
It may not be your number one spot for finding cool apps for your Android device, but the Amazon Appstore for Android is running a new promotion this week called "Geek Week," where eight of the most popular productivity and utility apps are now on sale for 48 percent off or more.
You wouldn't think that something so simple as a "suggested users" list would create so much controversy, but Google+ seemed to have accidentally ignited a firestorm when they introduced a new feature over the weekend: the "Suggested People to Follow" list now appears when a new user joins Google+.
The manual that's included with the Canon EOS 5D Mark II is a great starting point for learning the camera, but it's definitely not the only place you should be getting your information from if you intend to master your 5D Mark II. If you don't have the manual, you can download a copy of it here from Canon's website. It's great for learning the basics of the camera, but sometimes it can be vague and hard to follow. In order to capture the full potential of the 5D Mark II, you need to go a lit...
Circles. They are both the best thing and worst thing about Google+. They're great because they allow you to fine-tune who you're following and who you want to keep in touch with, making it easy to keep your family and friends separate from each other. On the other hand, they can be a pain to maintain, and you can easily become overwhelmed from the "noise" of popular posts, which make it hard to concentrate on some of the people you want to focus on. But if you invest a little bit of time in ...
It's no secret that Apple has retail stores in China, along with a large amount of Premium and Authorized Resellers. But a recent post by blogger BirdAbroad has caused quite a commotion in the world of all things Apple, claiming that in her home city of Kunming, there is another breed of Apple Store locations... "Un"Authorized ones.
Hangouts are one of the most fun features in Google+. As long as you have a webcam and a microphone, you can "hangout" with up to 10 of your buddies on Google+ and do just about anything. Of course, sometimes it can get kind of awkward when you are hanging out and you don't really have anything to say. This problem can be mitigated if you host hangouts with a plan.
One of the things I consistently notice amongst fellow internet users is that many people don't know how to properly search for stuff. Google may have served you well in the past, but I'm going to share a few little tricks with you to help make your search results even spiffier.
Okay, stop me if you've heard this one. You have a document that you want your co-workers' advice on. You attach said document onto a mass email. The first reply comes back with an edited version of the document. You begin to make changes, but another email comes in, with yet another edited version. Soon you're drowning in a desktop folder full of mismatched documents, all with the same name.
This weekend, I was on a trip to Binghamton. In the midst of unpacking my toiletries at the hotel, I found that my brand new razor blade had lost its cap. How did I find that out? Well, when I pulled my hand out of the bag, I found that my right pointer finger was missing a bit of its tip and dripping blood on everything. Thankfully, Nathan G. H. Shlivovitz was with me and knew what to do, but the experience helped me to realize that everyone needs a little first aid knowledge in life. Here a...
Earlier in June, we learned that Project Fi was going to carry three new phones, one of which was a device previously thought to be AT&T-exclusive, the LG V35 ThinQ. After much waiting, preorders are now open.
Ever since Apple launched 3D Touch in 2015, we've wondered when the feature would come to Android in earnest. While Android has supported pressure sensitive displays since Nougat and a few fringe manufacturers have taken advantage of it, none of the big OEMs have thrown their hats in the ring — that is, until now.
Snapchat users have clamored for the ability to share their Stories since the app's inception, and we're finally going to be able to with "Stories Everywhere." Similar to how Twitter gave people the ability to embed tweets in 2011, Snap, Inc. aims to make Stories even more accessible for those outside of the platform.
Just as we started running through the features packed into the Android Oreo beta for the Galaxy S8, Samsung has started pushing out the second beta to eligible devices. According to DroidVendor, the update is rolling out as build G955USQU1ZQK1 for the Galaxy S8 Plus. The rollout should arrive as an OTA for anyone that is currently running the first beta.
Some iPhone users who updated to iOS 11 can no longer see the "Message" icon in the share sheet when in apps such as Photos, which means they can only text or iMessage an image from within the Messages app itself now. This is a bug with remote management software which will hopefully get fixed soon, but until then, the solution isn't pretty.
Basically, I have been pondering this a bit. First Off:
Welcome back, my neophytes! Many of you might have a personal diary and might think Why do I spend so much time to write in the damn diary? or Why waste money on the diary, even though you would be wanting it? It's time you found out a solution!
While the OnePlus One is a great value, you could be plagued with a touchscreen issue or two. The most common problems come in the form of ghost touches and touches not registering with apps.
