QUES: Law professor, writer and political activist Lawrence Lessig, along with many other copyleft and free software activists, has criticized the implied analogy with physical property (like land or an automobile). They argue such an analogy fails because physical property is generally rivalrous while intellectual works are non-rivalrous (that is, if one makes a copy of a work, the enjoyment of the copy does not prevent enjoyment of the original). Other arguments along these lines claim that unlike the situation with tangible property, there is no natural scarcity of a particular idea or information: once it exists at all, it can be re-used and duplicated indefinitely without such re-use diminishing the original. Stephan Kinsella has objected to intellectual property on the grounds that the word "property" implies scarcity, which may not be applicable to ideas.

QUES: The total energy of a system can be subdivided and classified in various ways. For example, classical mechanics distinguishes between kinetic energy, which is determined by an object's movement through space, and potential energy, which is a function of the position of an object within a field. It may also be convenient to distinguish gravitational energy, thermal energy, several types of nuclear energy (which utilize potentials from the nuclear force and the weak force), electric energy (from the electric field), and magnetic energy (from the magnetic field), among others. Many of these classifications overlap; for instance, thermal energy usually consists partly of kinetic and partly of potential energy.

What usually consists partly of kinetic and partly of potential energy?
What is the answer?
ANS: thermal energy
QUES: On April 20, 2011, Sony shut down the PlayStation Network and Qriocity for a prolonged interval, revealing on April 23 that this was due to "an external intrusion on our system". Sony later revealed that the personal information of 77 million users might have been taken, including: names; addresses; countries; email addresses; birthdates; PSN/Qriocity logins, passwords and handles/PSN online IDs. They also stated that it was possible that users' profile data, including purchase history and billing address, and PlayStation Network/Qriocity password security answers may have been obtained. There was no evidence that any credit card data had been taken, but the possibility could not be ruled out, and Sony advised customers that their credit card data may have been obtained. Additionally, the credit card numbers were encrypted and Sony never collected the three digit CVC or CSC number from the back of the credit cards which is required for authenticating some transactions. In response to the incident, Sony announced a "Welcome Back" program, 30 days free membership of PlayStation Plus for all PSN members, two free downloadable PS3 games, and a free one-year enrollment in an identity theft protection program.

What didn't Sony call the special offer they handed out to respond to the breach?
