Hacking a voting machine usually involves getting inside and swapping out a chip or two, so you would think they would make them really hard to open up. Sure enough, it you look at a Diebold (now called Premier Election Solutions) AccuVote-TS machine, there's a locked cover keeping everything secure. The only problem is that even election officials lose their keys occasionally, so Diebold sells new ones to "Diebold account holders" through their online store.
Now this is where it gets really dumb. Right there on the order page is a picture of the keys (since removed), showing exactly what they look like. Dumber still, it turns out that every AccuVote-TS machine uses the exact same key, and dumbest of all, it's essentially the same as many of the keys used for hotel mini bars and office file cabinets. A group studying voting machine security at Princeton University found that with three blank keys, a file, and a small vice, they could easily make two working keys by copying the key pattern from the Diebold website.

RC cars are the cars of all ages; it doesnt matter if you are eighty or sixteen, there is simply the kind of radio-controlled car that you would enjoy. If you know how to take fun with these vehicles, you certainly will cherish the endless excitement brought about by them.
If you are getting your first radio-controlled car, you might consider the three most important things:
Ready-to-run (RTR) car or a kit
The RTR cars are most ideal for the beginners and those who do not have the skills for assembling the car. These cars will let you automatically enjoy their features and start them running through electricity-powered batteries. RTR cars tend to be a little inexpensive than building the car.
On the other hand, the kit will let you do the assembly works. For the enthusiasts, this has more advantages, as it will allow you to maintain it easily. If there are alterations and repair jobs needed, you would find these yet another easy task as you know how the chassis, engine, and other parts were put together.
On-road or off-road
On-road cars are designed for such speed needed in a smooth, paved surface. Also, if you intend to get into the race competitions, these are clearly your option.
Off-road vehicles are those trucks and buggies that have the ability to negotiate rough terrains, jumps, and obstacle courses. Naturally, these are not intended for racing events.
Electric or nitro-powered car
Simpler and slower vehicles are the choices for the beginners. As mentioned, rechargeable batteries are used to power the cars. Though they are clean and quiet, one disadvantage is they do not exude realism for radio-controlled car racing.
Nitro- or gas-powered cars are those intended for racing and higher-level of performance and power. In the recent years, the quality of these cars has much improved in terms of performance, safety, reliability, and aesthetics.
Having all these factors answered, you are now ready for your visit to the store. If you prefer building your own car, you will have the kit.
After getting the kit, you will need your red tool box and make sure every necessary tool is included. Specifically, the things you would need are: screwdrivers, flat blade screwdrivers, pliers, slip-joint, hobby knife (no. 11 blades), flush cutter, and needle-nose varieties. Adding soap could be used as a dry lubricant for the tight parts.
RC car kits cost a few hundred dollars but if you want higher performance and power you may add another bit of expenses. You can elect to acquire few pieces of RC car accessories or necessary parts for the upgrade. You can also finish the car with your own design you have in mind. Accessories and add-on parts are offered through local stores or online stores and you can check out their availability through them
To avoid getting mistakes along the process, study well the owners manual. Familiarizing with every step and process will make it easy for you to finish the job. Completion of the process will not finish in one sitting, so you better prepare yourself for this task. It would be wise to work in a clear, well-lit, and with an uncluttered area to avoid mistakes.
Get relevant information on how to start with your RC car kit
There are books, e-books, and other materials containing information and ideas about building cars from a kit that you can use for additional help. Accordingly, obtaining wisdom from experienced RC car racers would be very beneficial for you. Once you get all those things and information needed, you can build the fastest RC car in no time at all.

Northrop Grumman engineers in Redondo Beach, Calif., lower the LCROSS spacecraft into a vacuum chamber that simulates conditions in space. It will be destroyed while seeking water ice on the moon.
Astronomers hate the moon.
Its so bright that it blinds telescopes like the sun in a drivers eyes. Theres no atmosphere, and the geology is basically dead. Maybe thats why, decades after Neil Armstrong and Buzz Aldrin walked there, we have clearer maps of Mars than of our nearest neighbor.
But now, NASA needs to know more. The agency plans to return astronauts to the lunar surface in 12 years as the first step in establishing a permanent outpost. The base could be an ideal location for manufacturing processes best suited for low gravity, or for helium-3 mining to fuel future fusion reactors. The agency also sees the moon as the perfect construction site and launchpad for eventual manned journeys to Mars.
Water is a key ingredient in these grand schemes, because it can be broken down into oxygen for lunar bases and fuel for rockets. In 1998 a probe called Lunar Prospector spotted tantalizing signs of hydrogen in craters at the lunar poles. But no ones sure if the hydrogen is the chemical signature of water ice, possibly deposited by comets and meteors.
NASAs first step toward a moon base is the $491 million Lunar Reconnaissance Orbiter (LRO), a satellite designed to map the terrain in intimate detail. In January 2006, after several years of development, LRO engineers decided to use a larger Atlas V to launch LRO, creating 2200 pounds of extra cargo capacity. The agency put out the word to its 10 research centers: What can you come up with to make use of that space—before the earliest LRO launch window in October 2008?
Moon Crash
Here are some images for you of the moment when the spaceship touches the Moon.
