Three meaningful jokes When my wife had just taken a shower and her husband was about to start the shower, the doorbell rang. After a few seconds of quarrel about who should go to the door, his wife wrapped a towel and hurried down to open the door. She opened the door and saw Bob, his neighbor. Before she spoke, Bob said, "If you take the towel, I will pay you $800! When my wife thought about it, she took off the towel and stood naked in front of Bob

I woke up early this morning and will take a road test next week to learn to drive. When I got up at, the sky was not bright yet. My mother had already swallowed the bottle that Tongtong and ruirui had been drinking at night. My mother was thin and worn out. She had to take care of two children every night for more than two months, feed them. When he got down from the building, the master had not yet come down and pressed his doorbell (he lived on t

Reminder) 「 Sorry, the shipping person has already left. Maybe it's a traffic jam. It's coming soon .」The doorbell rang. "Mrs Li, this is your roast duck. Please sign the order .」(Acceptance Warehouse receiving to accounts payable) At, my daughter's phone number: "Mom, can I bring some friends home for dinner now ?」(The order is urgent and must be in stock) 「 No, daughter. Today, my mother needs to prepare two meals. It's too late,I am really sorry.

phone is really very old, and the old ones even have no letters on the buttons. He tried to dial the phone number to query the phone number, but the call was not slow. The card had a balance of more than 30 yuan. How long can this college student use the money? He opened the drawer and pulled out his old phone that had not been used for a long time but remained quite intact. Because this phone is not a chord ringtone and does not have the Internet function, he is eliminated. I still remember th

different objects, the interface is used. If you want to design small and concise functional blocks, use interfaces.3. If you want to design a large functional unit, use the abstract class. If you want to provide general implemented functions among all the implementations of the component, use the abstract class.4. abstract classes are mainly used for closely related objects. interfaces are suitable for providing general functions for irrelevant classes. The following is a metaphor I have seen

She dressed herself hastily. She hurriedly put on her clothes. 386. She hired a car by the hour. She rented a car billed on a hourly basis. 387. Someone is ringing the bell. Someone is ringing the doorbell. 388. The Smiths are my neighbors. The Smith family is my

product level 360 degrees free rotation, vertical 35 degrees tilt adjustment. The most important of its use of idle mobile phones as the main computing and display platform, greatly saving the cost of equipment, allegedly its host price only need more than 300, than the industry, a home can be much cheaper.(3) Housekeeping King Smart CameraThe first reporter was just attracted by its lovely appearance, and then found that it is a smart camera, support WiFi and 3G network, the product has video

. And an important feature is the large amount of data transmitted, can transmit video stream.So. Below we do a simple networking:Figure 1 WiFi Networking1, first. Computers, tablets, and mobile phones will have their own WiFi modules, so they communicate with the smart router over WiFi.2, for television, if the TV broadcast is network TV or network video, you need to use WiFi.In particular, most of today's TVs are equipped with WiFi or USB ports, which can be used to connect storage devices suc

following analogy:Like iron doors are doors (abstract class), you want a door I can't give (can't instantiate), but I can give you a concrete iron gate or wooden door (polymorphic); and can only be the door, you can not say it is a window (single inheritance), a door can have a lock (interface) can also have a doorbell (multi-implementation). The door (abstract class) defines what you are, and the interface (lock) specifies what you can do (an interf

hard to come, the old king squint his small eyes, curled up his hands to the sofa on the leaning.Ding dong! Ding dong! A few melodious doorbell, across the old Wang's heart."Come on, come on, Xiao Li?" The old king hurried up to the door to walk."I am Xiao Li!" "There is a poetic sound outside."Hurry in, please come in!" Come, take a rest on the sofa first, the old Wang smiled at the sister, this girl ran full head is Khan."Manager ... No... I ... "N

The number of instances of a class can only be instantiated once.For example: Xiao Wang and Xiao Li through the doorbell to communicate, first of all to judge the small Wang home whether there is a door, if there is no door, if there is a door directly back to the door.var Xiaowang = (function (argument) {var men;var Xiaowangjia = function (message) {this.menling = message;}var info = {Sendmsg:function (message) {if (!men) {Men = new Xiaowangjia (mess

Sign one word on the ticket ."(Acceptance, warehouse receiving, transfer to account payable) At, my daughter called: "Mom, can I bring some friends home for dinner now ?"(Oh, it's an urgent order intention, and the spot is required) "No, daughter. Today, Mom needs to prepare two meals. It is too late. I am really sorry. I wi

star network topology, and an important feature is that it can transmit video streams with a large amount of data. Therefore, the following is a simple networking: Figure 1 wifi networking 1. First, computers, tablets, and mobile phones all come with WIFI modules, so they communicate with smart routers through wifi. 2. For a TV, if the TV is playing a network TV or a network video, wifi is required. In particular, most of the current TVs are equipped with WIFI functions or USB interfaces, whi

inheritance ); A door can have a lock (Interface) or a doorbell (multiple implementations ). A door (abstract class) defines what you are and an interface (LOCK) specifies what you can do. (One interface is best to do only one thing. You can make a sound without a lock (interface pollution )) The following is an example of using an interface to implement polymorphism: 01. Create a New flying Interface Using System; using System. collections. generi

(read), then serve the Guest (send), the whole down waiter (process) in many places is blocked. With more guests (HTTP requests), the restaurant can only be serviced by calling more waiters (the fork process), but because the restaurant resource is limited (CPU), once the waiter is too much of a management cost (CPU context switch), this enters a bottleneck.Let's see how the Nginx is going to handle it.

resource is limited (CPU), once the waiter is too much of a management cost (CPU context switch), this enters a bottleneck. Let's see how the Nginx is going to handle it. The door of the restaurant hangs a doorbell (registered Epoll model of the Listen), once a guest (HTTP request) arrives, send a waiter to receive (accept), then the waiter went to busy other things (such as to receive guests), waiting for the guest to order a good meal called the wa
