News: Astronomical Observing News (4/4 to 4/10)
There isn't much going on this week, but be sure to try viewing the Spica-moon conjunction. It will be hard to view with the full moon, but it will be spectacular if you can snag a peak.

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.

If you've ever had teeth removed/minor surgery, you most likely received some laughing gas, or nitrous oxide. This gas creates a happy, lightened feeling, and causes instant laughter. In this article, I'll show you how to make some. BUT BE CAREFUL!!! DO NOT proceed in this experiment unless you have EXTENSIVE knowledge of chemistry!!! Misuse of this procedure could result in the production of LETHAL GASSES! However, the set-up is quite simple, if done correctly should not lead to any issues. ...
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!
I'm back with the third part to my laser weapon series (see part one and two), and I'll be explaining the function, application, and potential of semiconductor lasers, aka laser diodes.

So far, I've talked a lot about what's going on in the world around us, but it's time I come back to politics for a bit. That said, the name of this world is somewhat misleading, in the sense that I talk about everything, not just politics! But I digress again.
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.
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.
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.
¬¬Just about every business has a website these days but very few businesses know how to effectively use their websites to get more customers. There are two different things that a business owner needs to do to increase their website traffic: optimize their site so that search engines can find them easier and promote their site on the internet so that they have greater visibility. This article will discuss how to optimize a website.
In this article I am going to take a look at the Google keyword tool, which is one of many keyword tool programs that you can use to find your keywords.
In this article, I'll be exploring the basics of Python, i.e. variables, input and output. You'll need Python (2.7+), a computer, and some free time.
Today's guide is on creating a password protected folder on Windows 7 without any additional software. Yes, you heard that right. No extra software at all! This guide is intended for beginners. But please note, this method should not be used to store financial or otherwise highly confidential material. It might be a good place to hide a planning document for a family member's birthday party or similar occasion where you need to keep something secret temporarily.
In the first part of this series, we learned about darknets, as well as how they came about. But these patches of forgotten Internet are not the oasis of free information you might think. Despite being hidden—or just harder to come across—these networks are no more safe then anywhere else on the 'clear' Internet. The nature of networking and routing means your location is always known in server logs. It only takes one phone call to your ISP with your IP address to obtain both your physical ad...
In each day of our life, we see inflammation. We see it during sore throats and abscess formations in our bodies, and even slight tooth pain is a form of inflammation. Sometimes it's good when it fights to protect us from invading organisms, but sometimes it becomes bad when it occurs in inappropriate ways, like acne.

Lock picking is defined by locksmiths as "the art of opening a lock without the key". There's many ways to accomplish this, but I'm specifically interested in using a lock pick set. Since locks vary in shapes and size, it's better to stick with just one kind of lock at first. Most locks are based on fairly similar concepts, so sharing methods across locks is possible.

Dealing With Stress
In this article, I'll show you how to make a portable prank stun-baton. Powered by static electricity, simply charge up the baton, and discharge it for a static surprise. The concept behind this device ties in with Leyden jars, and their tendencies to retain static electricity.
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.
In this article, I'll show you how to make a glowing orb. The orb is a fun, round flashlight useful for lighting your path in a magical way. Consisting simply of LEDs, a tennis ball, a battery and a switch, it's a great simple project for beginners with electronics. Here's a video of it in action: Tools and Materials

Note: This shower is only visible in the Northern Hemisphere. The Quadrantid meteor shower is one of my personal favorites, mainly because of the amount of meteors it produces. You can sight more than 100 meteors per hour- that's more than 1 meter per minute. Even though that doesn't sound like much, it will make your observing experience much more exciting. The peak is short, typically lasting no more than an hour or so. It is more easily observed on the fourth, with its peak at 1:00 AM EST.
Windows 8 Beta (Developer Preview) It wasn't that long ago Windows 7 was released - now Windows 8 Beta is here. I did do a Google search to see when the stable version will be out but wasn't able to find an official statement from Microsoft. However - I saw several articles on Google hinting that the final release might be in August or there about.

Welcome to Minecraft World! Check out our advanced tutorials and come play on our free server. Welcome back to Minecraft World's Ultimate Survival guide! A few days ago, we reviewed a good way to start off right when you spawn, plus a small rundown of the mobs. Now we will continue on to combat strategies. Note that these are strategies, not specific How-To's, so the best way to get better at it is to do it yourself!

MineCon 2011 (held at the Mandalay Bay in Vegas) was in a word, awesome. The crowd was overwhelmingly young, the vibe was fun and nerdy, and best of all, the costumes were inspired. Below are my favorites, which unfortunately aren't of the best quality (lighting was low and super yellow, which wasn't helped much by my standard point-and-shoot). If you happened to attend Minecon as well, post about your experience to the community corkboard... if you're pictured below, please comment!
Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.
"Google+ is dead." How many times have you read that in the past few weeks? It seems like I can't get away from this notion that Google+, as a social network, is a total failure. Don't feel too sorry for them, though. +Bradley Horowitz isn't worried. In an interview with VentureBeat, he explains, “Six months from now, it will become increasingly apparent what we’re doing with Google+. It will be revealed less in what we say and more in the product launches we reveal week by week.” Indeed, som...

Aesthetic Houses: What are they? If you've played Minecraft for some time now, you most surely know how hard it is to build a great looking house to live in, that meets both your vision of your dream house and expectations for functionality. This brings us to the definition: in terms of Minecraft, its a structure that dosen't compromise beauty and appeal for functionality.
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.
It’s been a pretty big week for Google, and Google+ itself. There were a number of articles proclaiming the end of Google+, because allegedly traffic dropped over 60% after it opened to the public. Then +Steve Yegge accidentally posted a long rant on Google+ itself, which was originally meant only for Google employees and colleagues to see. Interestingly enough, the most inflammatory content wasn’t actually about Google itself, but about the horrible work environment at Amazon. The accidental...
