Just called apple. They said they can replace the device but I have to pay $149 to replace it. What was a clear manufacturing issue (i did no damage to the phone) now is going to cost me money. Plus I am out of the phone for a few months now. They just turned me from an apple lover to apple hater.
1. 1. 0. The XOR gate (sometimes EOR gate, or EXOR gate and pronounced as Exclusive OR gate) is a digital logic gate that implements an exclusive or; that is, a true output (1/HIGH) results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is one or the other but not both. XOR can also be viewed as addition modulo 2. As a result, XOR gates are used to implement binary addition in computers. A Half adder consists of an XOR gate and an AND gate.
Aggregate functions can be used in both the SELECT and HAVING clauses (the HAVING clause is covered later in this chapter). Aggregate functions cannot be used in a WHERE clause. Its violation will produce the Oracle ORA-00934 group function is not allowed here error message.
