In this article, I'll show you how to create a simple yet accurate demonstration of the "rising ionized gas" principle. In other words, a transformer, two metal prongs and lots of evil laughter. Remember those large "towers" in the background of Frankenstein movies with a "lightning bolt" rising upwards every few seconds? That's called a Jacob's Ladder; one of the coolest awe-inspiring demonstrations of high voltage. Here's a video of the final product: Materials and Tools
Piezoelectric Energy In this article, I'll show you how to make a small, wallet-sized device that generates electricity from kinetic energy.

I've come across a few very stubborn Xbox consoles in my day. A previous Null Byte demonstrated how to fix the Xbox with just eight pennies and some electrical tape. But if you've got one of those hell-born boxes that just refuses to be fixed in any way, shape, or form, there is always one last ditch approach. I'm talking about the infamous "towel trick". It works over 90% of the time, from my personal experience. Though, please note: This is only a temporary fix.
If you take two flat mirrors and place them front to back and look at them, you can see an infinite number of reflections. While this is a self-replicating pattern and can be somewhat mesmerizing, it isn't anywhere as interesting as looking at the chaotic scattering of light that can occur between 3 or 4 spheres.
Introduction In this post we will look at how to access a PosgreSQL database in your C/C++ application. It's not as hard as you might think, but you need to understand the procedure and the functions used.
Tomorrow is another day of election (PSG). I have to wake up early to set up the computers on both computer rooms. The election process is computerized, making the counting of votes the responsibility of the computer. What makes this year's election special is that for the first time in 3 years (correct me if I'm wrong), there are competing parties. The result is something to look forward to especially for me who contributed in the creation of the system.
This simple meal is dedicated to all food lovers around the world and to all the Filipino diehard fans of "dinuguan"—otherwise known as pork blood stew, blood pudding stew, and even chocolate meat. I don't know where this recipe originated, but I would like to thank my girlfriend's mom for teaching me how to cook this.
No doubt you've seen some of the hack logs being released. One part that stands out over and over again is the heavy database usage. It used to be early on that virus and hackers would destroy data, usually just for lulz. However, with the explosive commercial growth of the Internet, the real target is turning into data theft. You should learn how this happens so you can protect yourself accordingly. Let's take a look at what makes this possible and dare I say, easy.

Both have been well-reviewed and spent time near the top of the XBLIG sales charts, but its success couldn't be rivaled by what wa...
Three years ago, Double Fine productions held an in-house event called the Amnesia Fortnight. The company was split into four teams, each of which set out to spend two weeks developing an idea for a small game and present it to the other groups at the end of the duration. All of the ideas turned out to be winners, and founder/owner Tim Schafer secured publishing deals for all four games to be released on a combination of XBLA and PSN. In honor of the excellent Trenched becoming the third game...

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.

Welcome to part three in a series about steganography, the art of hiding things in plain sight. We are practicing steganography because it can be a useful skill if you don't have access to encryption software, or need a quick solution to make sure the sender and recipient are the only ones who are able to read your message.
Your IP (Internet Protocol) address is your unique ID on the internet. It's synonymous with your home address. Anyone in the world can contact your computer through its IP address, and send a retrieve information with it.
To go Open Source or go proprietary? There is a common conception that open-source is unsafe and insecure and therefore companies should rather go for proprietary solutions. They think that because software is termed "open-source", that the world can see the vulnerabilities of the software and might exploit it, and less informed people tend to think that open-source software can be modified while it is running.

If you found the world renown Body Worlds exhibition gnarly and perverse, perhaps you'll find this latest parade of plastination a little less so—considering we don't share the same DNA as these specimens of jerky-in-the-name-of-science. The Koerperwelten der Tiere—or Animal Body Worlds–doesn't showcase preserved corporal matter, but rather 20 odd plastinated mammals, currently on display at the Cologne Zoo in Cologne, Germany.
