Then I wrote something that was not written yesterday. Recently, I received a mail about the elderly. The elderly living alone, living alone, or being sent to the nursing home, were so sad. Coincidentally, chestnuts criticized me last week and said, "Let me go home and see more. He is different from me. Otherwise, he will go back every week. I usually don't pay much attention to what he says, but he can always come up with something unexpected to me from time to time. Think about it too. Why do

; Nan has other amazing features. For any floating point operation, if one or more of its operands is Nan, the result is Nan. This rule is very reasonable, but it has strange results. For example, the following program prints false: class Test { public static void main(String[] args) { double i = 0.0 / 0.0; System.out.println(i - i == 0); }} The principle behind this Nan calculation rule is that once a computation produces Nan, it will be damaged, and no further computation can f

Due to the level limit, the node must be 1 or less than the level of M, then for each of the upper and lower difference between the interval of M to find the shortest possible, and finally take the minimum value.Easy to understand, draw a very bad picture, we gather live to lo

is to get it through the constant () function. To determine if a constant is already defined, you can use the defined (Stringname) function to return true successfully, otherwise false. 1.3 Defining variables and assigning values to variablesUnlike many languages, it is not necessary to declare a variable before using it in PHP (PHP4.0 needs to declare a variable before), just assign a value to the variable.1.4 operatorOperators, like other languages, include +-*/() | ^ ~ 1.5 Functionsfunction

When the test is on the real machine, it appears for example the following information, and the application hangs.Restore the connection to "" XXX "for IPod" and run "xxx" again, or if "xxx" is still running, you can attach to it by selecti ng Debug > Attach to Process > XXX.This is because the application suddenly consumes a lot of memory, and then allocates the scheduling memory, an error occurs, causing the system to shut down the app process.Be able to see if it's loaded with lots of picture

First, a simple understanding, and then add: To solve the consistency problem of hadoop distributed systems, many people have proposed many protocols, including the paxos algorithm (proposed by latex, algorithms need to be learned ), However, Chubby is not an algorithm or protocol. It is a service and a lock service. The implementation of this service is a distributed file system. Why not use protocol? In addition to implementing consistency, this s

number greater than proposal K, Assumed to be proposal K2. Similarly, the value of proposal K2 is equal to the value of proposal K or proposal K3, and KAs we can see, the P2C condition is basically the key point of the above two-phase protocol 1, but there is a problem, this p2c condition requires to find out this "maximum ordinal value" and the proposed proposal must be an atomic operation , which is actually difficult to achieve, so, The two-phase protocol is a clever way to avoid this proble
