This article presents some twitter-sizeprograms that trigger the bug. The mechanics are so simple that can be easily explained to anybody possessing some minimal knowledge about how operating systems works. Beside being a good educational example this is also a scary proof that very mature code can still be vulnerable in rather unsophisticated ways."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
