The Nova-conductor process runs at run time, where a single process consumes CPU 100% periodically, with a period of approximately 2 minutes. debugging and troubleshooting, found that the reason is that nova-conductor in the execution of a database operation, the request data volume is huge, only the database lookup time is 10s, the return data size at 2MB. Causes the data to run out of CPU during serializa
Problem Description: On the bus, the driver and the conductor's activities are:Driver's activity: Start the vehicle, normal driving, stop.The conductor's activities: Closing the door, selling tickets, driving the door. In the continuous arrival, stop and drive of the automobile, the signal volume and p,v operation are used to realize their synchronization. Problem solving; We can use two signals to achieve the synchronization between the driver and the condu
When learning the builder model, there is always a problem that cannot be understood, that is, why there is a conductor class. I feel that no conductor class is just as simple and quick, and even easier to understand than no conductor class. The following is an example program written in C ++: // builder. CPP // use the builder mode # include

The demo thread does not consider the full logic. For example, 50 = 20 + 20 + 5 + 5 or 50 = 10 + 10 + 20 + 5... In this example, only the two cases are determined when the value of 50 is changed to zero. The other cases are not considered. Focuses on demonstrating the thread process ....Code:

/* = Question: Imitate Example 8-10, design five people to buy tickets in queue, and the Ticket Selling R
On the train, a pretty female conductor stared at a middle-aged migrant man and shouted, "check tickets !"
The middle-aged man rummaged all over and finally found it, but it was taken in his hand.
The conductor smiled at him and said, "This is a children's ticket ."
The middle-aged man looked red and said, "Isn't the children's ticket the same as the fare for the Disabled ?"

What happened on the train (tears after laughter! Don't regret it !)
On the train to ***, a very beautiful flight attendant stared at a migrant worker.
Middle-aged People shouted "ticket checking ".
The middle-aged man rummaged all over and finally found it, but it was taken in his hand.
The conductor smiled at him and said, "This is a children's ticket ."
The middle-aged man looked red and said, "Isn't the children's ticket the same as the
supply the power of the system to a device that needs power, providing a stable voltage and a complete current loop, we only focus on three electrical characteristics of the Power distribution system: resistance characteristics, inductance characteristics and capacitance characteristics . The
resistance characteristic Resistor is a physical quantity that characterizes the resistance of a conductor to a DC current, usually denoted by R, whose

Class mythread2 implements runnable {public void run () {// thread body for (INT I = 0; I
Now we use a classic case to illustrate the differences between the two methods:
Ticket sales example. This example is basically available in every Java getting started book!
Requirement: If you have 50 tickets, you need to sell them in three ticket sales windows. You can use two ways to enable the thread to buy tickets. What are the differences between the two methods?

. The builder mode structure is 8-2:
Figure 8-2 builder mode structure
The builder mode structure includes the following roles:
● Builder: It specifies an abstract interface for each part of a product object. Two methods are generally declared in this interface. One method is buildpartx (), they are used to create various parts of a complex object. The other method is getresult (), which is used to return complex objects. Builder can be either an abstract class or an interface.
● Concretebuilde

there is an electric field between the two conductors inside and outside the coaxial cable, there is a certain amount of electric capacity. When the conductor passes through the alternating TV signal, a certain amount of electric sensing will be generated. These inductance and capacitance are distributed in the cable, the capacitance combination of the series Inductor and the parallel capacitor is measured by the electric sensing Volume L and the ele
1. Power: (1) Definition: the number of electric resources contained in an object is expressed by the symbol "Q.
(2) unit: the colon (database), represented by the symbol "C.
(3) inspection: Electric Appliance (structure, principle, and use ).
2. Current: (1) Definition: the electric power passing through the cross-section of the conductor within 1 second is called the current intensity (current ). It is represented by the symbol "I.
