Before jumping right into becoming the next James Neely or Moose Peterson, you're going to have get situated with your new digital SLR. No matter if you purchased the Canon EOS 5D Mark II body and lens separately or together, you've got everything you need to get started except the CompactFlash (CF) card. If you plan on shooting in RAW or capturing HD video, I suggest getting an 8GB or larger CF card. If you can afford it, maybe even opt for a high-speed UDMA card.
In this article, I'll be showing you how to make a simple yet effective static electricity generator. Basically, this device allows you to carry a constant static charge on your body and discharge it on anything grounded or of opposite polarity. The electricity generated is around 8-10 kV, at a very low current. The shock is enough to startle your friends, just like a static shock from a trampoline or carpeted room. You'll need a little experience in soldering and circuit design to build the ...
Welcome to another Community Byte announcement from Null Byte! The goal of the Community Bytes is to teach people in a co-operative, hands-on manner. Learning from experience and immersing yourself in a subject is the best way to learn something foreign to you, so that is exactly what we do! In our sessions, we have started to both code and complete HTS missions. This means that there is something for everyone here, so make sure you join us.
I just found out that I might be expected to tip all the vendors... on top of the exorbitant fee they charge! Sigh... Here is a great tipping cheat sheet courtesy of theknot.com.
1. Extend your engagement. A longer planning period means a better chance of getting the best vendors in your price range. Plus, you can typically lock in rates that might increase by the time your wedding date arrives.

Devil2005 has created a video on compiling and configuring dhcp daemon, or dhcpd, from source. He's using the Fedora 9 distribution of Linux for the video, but the lessons learned should be applicable to other distros. For that matter, even if you are not interested in installing dhcp in this way it's still a good lesson on how to download and compile various applications from source. Compile and configure dhcpd from source in Fedora 9.
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.
In this series on weaponized lasers, I'll be exploring the function, operation, strength and building instructions for three basic laser weapons; CO2, Diode, and Flashlamp. These laser types are just a few of many, selected because of their simplicity and basic construction (depending on your experience).
Find a great location, set up area with an attractive advertisement sign charging $5 for the foot bath, a recliner, foot tubs filled with poo & labeled with scented poo names and tubes of water. Each tub will have a recliner or 1 recliner then let person choose the foot bath they want. Have a table prepared with towels, and lets not 4get the foot bathers.
Airsoft doesn't get any better than a cloud chamber BB machine gun, aka Cloud BBMG. This design has an incredible rate of fire. If you've got a full charge of compressed air, it can easily fire more than 50 rounds per second at a 350 ft/s muzzle velocity. Since this is a legit airsoft build, it should be handled safely with the same care as any other airsoft firearm, and you should be wearing the same protective gear—protective mask, safety glasses, etc. My video details the build of this bea...
Dandruff -- the embarrassing white flakes that end up like snowfall on your shoulders and clothing. There are plenty of dandruff shampoos on the market to choose from, unfortunately, they are all very expensive. If you have ever wondered what ingredients make them so expensive, the simple answer is there are no expensive ingredients that make them so effective. So, the next question might be, why are they so expensive? And the answer to that is dandruff shampoo companies know they can charge ...
Musical boxes are best known for their kitschy designs and somewhat trivial renditions of musical masterpieces. They tend to frequent the dresser of young girls or elderly woman hanging on to their youth, and for the most part, they remain cutesy and harmless, but when featured in movies like The Silence of the Lambs and Black Swan, they become downright creepy.
Want to stick it to your mobile carrier by porting your cell number to Google Voice? Now you can! On Wednesday, January 19th, Google Voice began allowing select users to transfer their personal numbers to Google Voice for a one-time fee of $20. Though the feature is still in limited release, Google has stated that they intend to make the feature available to all Google Voice users "in the near future." Terrific, right? Not entirely!
Eventually, we plan on doing some root the box competitions here at Null Byte, but we're still looking for a server to play on. Anyone want to donate one? You won't regret it. Root the box is like 'king of the hill', except you have to hack a server and maintain access. Each server will have numerous known security holes, but until then, let's get back to the regular weekly coding sessions and realistic hacking missions on HackThisSite.
We'd like this to be one of the last HTS mission announcements, at least for now. As soon as Null Byte finds a server to play with (anyone want to donate one?), we are going to start doing root the box competitions, which is like king of the hill, except you have to hack a server and maintain access. Each server will have numerous known security holes. But for now, back to the normal flow of things...

The community tore up the first realistic mission last week. You've applied the techniques learned in the basic missions to a real scenario, so I'm pretty content. The realistic missions are where the learning gets intense and where we can apply real knowledge to extremely realistic situations. We will also be continuing the normal Python coding and hacking sessions. These sessions are created to bring our community together, to learn from each other, and grow together. Everyone is welcome, f...
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.

Here's a noncomprehensive list of current features confirmed and experienced in Minecraft 1.8. If you have anything to add, please do so in the comment section below.
The iPhone and iPod touch are nearly identical devices, especially now that Apple has added a front-facing camera to the iPod touch. All that's missing is the phone part. With the help of Lifehacker and apps like Skype and Line2, you can save some money by turning your iPod Touch into an iPhone, without the need to jailbreak.
Between school, work, and your personal life, there's a good chance you have multiple Google accounts. Most Google apps let you log into all of them simultaneously to receive applicable alerts when they arrive. Well, there's a dead-simple way to switch between these accounts, and it just takes one swipe
I came across this post, and while it's not specifically steampunk, I think it's still very applicable. Every steampunk wants to have cool pictures, but not every steampunk knows how to get them. A good photographer will help you pose, but not everyone has access to professional photographers. Since you can't rely on having posing advice during a shoot, you should familiarize yourself with some of the tips in this post. Maybe someone on this site can write a steampunk-specific guide to posing!
We all love it when the Google logo changes to celebrate or commemorate special events— pop-culture touchstones, civic milestones, scientific achievements and holidays— their latest one for this holiday season is a Christmas card to everyone— an interactive Google Doodle with 17 artworks from different artists, each depicting a seasonal greeting from a variety of cultures and countries.

Police in Milledgeville, Ga., say they handcuffed a 6-year-old kindergartner for safety after she allegedly threw a tantrum at school, tearing items off the principal's wall and upending furniture, WMAZ-TV reports.
Tesla coils are electrically satisfying in so many ways. But what happens when a guitar-playing city coil has a run-in with a backwoods, banjo-playing, inbred coil? A musical duel to the death! Watch these two Tesla coils battle it out as they play Dueling Banjos. Shocking. Just shocking. Okay, so it's no secret that Tesla coils can create a wonderful light show of electricity, but by modulating the frequency, they quickly turn into powerful singing Tesla coils—the key to any electromaniac's ...

You might be sitting there thinking that I'm crazy, but the truth is you're only partially right. You can get free text messaging for life, all for a cheap, one-time fee. But, how can that be possible? An exploit in AT&T's prepaid GoPhones is the culprit behind this sweet, oh-so rare opportunity for exploitation. The exploit grants a lifetime of free texting, assuming that the company stays afloat from now until the end of time.
