Video games have been a purely digital medium for some decades now. They exist in the electronic nether, embedded on discs and projected on screens. Since digital distribution has gained popularity, even the physical manifestation of the game disc is going away, leaving games (especially digitally distributed indie games) more ethereal than ever before. It is unclear whether this slightly unsettling fact was on the minds of the three people who made Receipt Racer, but regardless, it stands as...
Have an old-school tabula recta lying around? No? Then just print out the chart below. Nothing ensures better password security than this centuries-old cipher technique. Here's how it works, via Wikipedia:
Using copper pennies (be sure they are older than 1983), lemon juice, paper towels and sandpaper, you can construct your own DIY battery that generates enough juice to light up an LED.
How to train a cat to use a toilet - really. I could not invent this stuff. When I first saw this video, I knew my life would never be quite the same. This ranks up there with the invention of electricity or the discovery or DNA. Now, I don't need to smell that litter. I don't have to change it. I don't have to buy it in the store anymore.
There is a near-infinite amount of ways a computer can be broken into. But that does not mean that there isn't a reason to secure our computers as best as we possibly can. It's like the principles of a secure house. Which are the most secure houses? The ones with locks and advanced alarms, obviously, but not for the reasons people normally think.
PETA wouldn't consider James Auger and Jimmy Loizeau's ingenious flypaper clock very eco-friendly, but I might beg to differ. The clock doesn't require any electricity or batteries. Instead it captures flies and converts the bodies of the dead insects into energy. Eight dead flies makes for roughly twelve days of power. Not bad.
Make My Mondays Meatless! One day a week join in on cutting out the meat! This Presidential initiative revived by The Monday Campaigns in association with Johns Hopkins, rolled out this program to the Baltimore public schools, then San Francisco went meatless and now celebrity chef extraordinaire Mario Batali and his fleet of fabulous restaurants said I'll play too! Now you too can help fuel this fire!
An experiment was carried out at our laborataries to investigate the flow through two pipes of same diameter fitted at the same height from water level inside of a water tank as shown. It is found the longer pipe line inside the water tank generates a higher speed resulting more powerfull flow. Flow in this pressure pipe develops due to gravitational accelaration on a horizontally flowing water column also, when it is an enclosed stream of flow. If this length is short it is not possible to d...
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.
More password cracking action from Null Byte! Today we aren't going to be cracking passwords per se, rather, we are going to learn the basics of generating rainbow tables and how to use them. First, let's go over how passwords are stored and recovered.
The noble board game has stalwartly staved off elimination in the face of more technologically advanced video games for four decades. Try as they might, video games just can't seem to surpass them as an easy-to-use diversion for large groups of seated indoor people.
In 2008, Audiosurf came out on Steam, creating the psychedelic music game genre. If you haven't played it in the intervening three years, you're missing out on one of the coolest things in video games. The player selects any MP3 on their computer, then the game builds a unique level based on that song, which the player must then navigate whilst playing a block-matching, Tetris-like puzzle game. It's an incredibly compelling audiovisual experience, one with immense replay value and surprisingl...
Welcome back to the two-part series of Ten foods to eat for clear, acne-free skin. Check out part 1 here.
From ZDNet: "A group of students in China have created PhotoSketch, a project that does exactly what I just described: it takes a rough, hand-drawn sketch, scours the web for photos that match, and runs them through an algorithm, stitching it all together."
Ever wonder how all of those tiny chips and components can fit inside your laptop or smartphone? If you tried to squeeze them in there yourself, your laptop would quickly become too heavy for your lap, and your mobile phone would need wheels to stay mobile.
In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet. The idea originally (at least, prominently) came from Nikola Tesla (read more about this amazing inventor here), who used his Tesla coils to transfer wireless energy to light bulbs in demonstrations (photo below). However, the circuit described in this article consists of a flyback transformer, n...
It's another Monday, which means it's once again time to highlight some of the recent community submissions posted to the Math Craft corkboard. Additionally, I thought we'd take a look at the process of stellation and make some stellated polyhedra out of paper.Rachel Mansur of Giveaway Tuesdays posted a video from animator Cyriak Harris, which zooms into fractal hands, where each fingertip also has a hand and fingers. A few more details can be found here, as well as some other really cool pic...
In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "sta...
If you've gained entry into Google+, one of the first things you should do is adjust your Google account settings. Your settings will now look quite different, and you can adjust your notifications, password retrieval methods, and more. There are many settings that you may not have been aware of before.
Minecart rides primarily serve two different functions—transportation or entertainment. We rarely see minecart-based transportation systems in Minecraft these days because most servers support warps or allow users to set multiple homes that they can simply teleport to. That leaves the primary purpose of entertainment.
