Assuming you are shooting the paintball at the average velocity of 91.44 m/s (300 ft/s is the maximum velocity that fields will allow you to use although the paintball could be fired faster but with less accuracy), the paintball's maximum height it could obtain would be 426 m (1397.64 ft) above the shooter. However at this height, the paintball has no more energy.

If the drone is flying at 1000 ft (304.8 m), you can expect the paintball to be moving at 48.86 m/s (160.30 ft/s). At this speed, the paintball probably won't even break on the target.

Conclusion, you might be able to hit the UAV and *possibly* break something but chances are you will miss anyway and the paintball won't even break.

Also, none of this accounts for drag or wind speed which would slow it down even more.

Install tons of super bright IR LEDs inside the bus. Most cameras will probably pickup the IR light and it will hopefully overexpose any shots they try to take [with their phone they smuggled in after you confiscated all devices before they got on]. In addition, install IR filters on your own cameras to try to filter out the IR light being blasted inside.

It was mostly things like remote controlled power strips, IP cameras, thermostats, and electronic door locks. I'm not surprised they stopped selling the service since most of those things either don't need a computer to control (IP cameras with a built-in server or a central reciever for multiple cameras) or could just be set to a timer (power outlets and thermostats). It was a neat service for people who didn't want to put in the effort to setup their own stuff and wanted a all-in-one deal to control all of those things but kind of useless in the end.

Considering the application runs on your phone, it pulls the number from the phone automatically. You also need to log into the application using a username and password so the phone number isn't used for anything really affecting your login. The phone number is used to help anyone that has your phone number in their contacts to find you on snapchat. Unless you make your snapchat username the same as your real name, there is nothing tying some random collection of letters to your phone number other than this DB.

Also, the previous exploit only worked if you knew a valid phone number that also happened to be a snapchat user.

In some carburetors, the newer ethanol mixed gasoline will separate so that the ethanol gums up inside the carb and basically disables the engine until you break it down and clean it out. I've never had the issue with a car but I've had at least a couple of ATVs where the fuel separated after a long time in storage.

So when it gets released and pushed out over Windows Update, the average user's install won't break because some little driver has an issue with how Windows 8.1 does things. Having the RTM out early also allows OEMs to make sure they are picking hardware that will work best with Windows 8.1 and have 8.1 machines ready for to be sold when 8.1 drops. By not having an RTM, Microsoft is telling everyone to go screw themselves and that they'll have to figure out if stuff works on Release Day.

Scale is used to describe how an objectâ(TM)s size and/or weight relates to the world around it. The scale at which something is built also strictly determines which materials and techniques will best be suited for that particular situation. Engineering is a complex field and the scale of things is one of the main reasons for that. I should point out at this juncture that I am not a structural engineer myself, more civil (in both meanings of the word!)."

nk497 (1345219) writes "Flash memory could soon be a thing of the past, according to US startup Crossbar, which claims it's close to bringing resistive RAM (RRAM) to the market. Crossbar is touting impressive specs for the RRAM technology, promising 20 times the write performance at a fraction of the power consumption and size of the current best-in-class NAND flash modules — and squeezing terabytes of storage capacity onto a single chip the size of a postage stamp. The company also claims its technology can retain data for up to 20 years, compared with the standard one to three years with NAND flash."
