The weapon works by basically smashing into something else, transferring most of that kinetic energy into whatever it hits which ultimately ends up as heat. This is the same reason brake pads on cars get hot, transfer of kinetic energy into heat.
When the projectile hits something and stops, the bullet and whatever it hits will get very hot. The projectile is probably made of metal which is in fact very flammable if you get enough oxygen to it. So there is a fireball, either because whatever it hits is flammable or because the projectile/whatever it hits is burning.
When you hit something that fast the behavior of metals changes. The speed of sound (see * below) in metal is high but if you hit something fast enough, then you can actually exceed the speed of sound in a metal and the rear of the projectile will carry on moving as though it hasn't hit anything when the front has hit something. This is the same idea of a shock-wave in air but it's in metal. Heres a good youtube video:
Well needless to say this tends to result in some funky stuff, like the metal bullet tearing it's self apart into lots of small pieces. This is a big driver in some anti-tank weaponry. If you hit the armour just right then you can actually get the inside of the tank to shatter, basically turning the inside of the tank into a shrapnel grenade, killing the operators.
If the projectile shatters then it's going to be hot and have a large surface area and you can get lots of oxygen to it which will result in a fireball, potentially it will burn about as hot as 1000 K. This to me seems like a good thing to design for because the added heat is going to do things like start fires and ignite conventional bullets/warheads and burn through armour.
* The speed of sound refers to the maximum speed at which a mechanical vibration (much like the pressure changes that cause sound. Not like light, RF, or electricity) can travel through a medium. Mach1 refers to that maximum speed of those wave's permeation through air, however different media such as water, metal, and glass will have different values for that maximum speed.
So, as the projectile hits some theoretical immovable object, the front will stop, but the rest will continue collapsing in on the front, faster than the pulse created on initial impact (a mechanical vibration that would otherwise influence the rear of the projectile to slow down) can travel to the rear of the projectile.
A bad, but visual representation of this is if you had a long line off cars driving down the freeway bumper to bumper. The first crashed and was brought to a halt instantaneously. In a normal crash each car behind would generally apply brakes and slow down before impact. However, for this example, everyone is driving faster than their own reaction time, so they are part of the pileup before they have registered an accident happened in the first place.

"The cane toad is native to South and Central America, but when its introduction to regions of Hawaii, the Caribbean, and the Philippines to fight pests in sugarcane fields yielded impressive results, it was quickly imported to various other regions worldwide.
Unfortunately, cane toads have a nasty habit of not just eating crop pests and insects, but also just about any terrestrial animal that they can fit their grotesquely huge mouths around — which is saying something, given that they can grow to over 30 cm in length. They also secrete toxins capable of killing just about any animal they come in contact with (humans have died after ingesting their eggs), meaning that they tend to be seriously lacking in the natural predator department."
so for all those being critical of this vaccine please keep in mind it's not supposed to "make you quit". It's more like it takes away your reason for doing it. Smokers will no longer get the good feelings from a cigarette so they will be more inclined to quit. If used as a vaccine they will be less likely to start again or start in the first place.
The loose-knit collection of hackers said it would shut down jihadist websites in retaliation for the terror attacks on the Paris-based office of the French satirical newspaper and a subsequent attack on a Jewish deli on Friday.
Now it has emerged that the group, which holds freedom of speech sacred, claimed on Twitter that it had struck ansar-alhaqq.net, a French terror-mongering website.
The Twitter account, @OpCharlieHebdo, also posted '#TangoDown', a reference to a military term meaning a terrorist has been eliminated. Source"
This thing actually works, question is, how can we use this tech in a proper
In addition I'd like to point out that there are countless studies that support the conclusion that a cosmic impact triggered the Younger Dryas cold period and only a handful that support otherwise.
"What’s most exciting about this channel of research is that it gets at the kind of complex, subtle prejudices that most people can’t even articulate if asked directly."

They are going to try to find racism where none actually exists and then call white people racist.

This one doesn’t need too much explanation, but try telling your mother that all she was doing for nine months was “knitting.”

Customer: "Hi, I'm A++ and MCP certified and I have a certificate from Devry so I know my stuff but I can't get my internet working"
Me: "What makes you say it isn't working Sir, what exactly is going on?"
Customer: "I can't load any websites except ones I've seen before, I tried restarting but it's just doing the same thing"
Me: "...type ipconfig, what do you see?"
Customer: "...static IP..."
Me: "Sir, do you have a kid who uses your computer for gaming? You have a static IP, that's the issue. follow these instructions and it will work..."
Customer: "No, I certainly don't have a static IP. I looked for that. The issue must be on your end"

One example came from the language training I took. The training was for English speakers to learn French so they spent 30 minutes teaching us a few words, counting and the alphabet in Kurdish. WTF right?...wrong!! it was brilliant. None of us had a clue about Kurdish so when they tested us they found out what we learned in that 30 minutes. That let them know our potential to learn, motivation etc.
SO WHAT? In a job interview you already know they have a certain base of knowledge from their resume. Now give a quick 5-10 minute talk on some obscure programming language, database concept...whatever. Then ask the interviewee questions on it, ask them to expand concepts that were taught. How they react and the quality of their answers will give you great insight into their potential.
