Waves-like! The click animation effect of the cool interactive experience, waves cool
Waves click effects are inspired by Google's material design and are easy to use. You only need to introduce waves.min.css and waves. min. js to the HTML file. Use touchstart and touchend events to support mobile devices. Come and try
Google Material Design believes you also know a lot, but at present both the application side or the Web side, can refer to the case is still few. In addition to "Material design some related Chinese materials/resource Collection Summary" for the purpose of the article, introduced a kind of Google Material design circular wave (ripple) Click Effect Plugin waves.Google Material Design has a special effect, click on a color block area will have a circular wave (ripples) of the effects of the fade

When you see this animation on the left, you may not believe that it was actually made from a computer. This is the charm of the special effect of water waves. This small animation is fromProgramIf you want to execute the source program and see the actual effect, you can download ripsample.zip (92 K ). (Contains the source program and executable files.

Researchers at the Japan's ATR International Electrical Communications Apex Technology Institute and Kyoto University in Japan say they created an AI that can read human brain waves. They build a neural network that can not only read, but also reconstruct your mind.
Specifically, according to the Zme Science website, "the team created an algorithm that can interpret and accurately reproduce (reproduce) images or imagined images that a person sees." ”
last few lines can be a good way to reduce the number of time_wait sockets, but for squid, the effect is not small. This parameter controls the maximum number of time_wait sockets, preventing squid servers from being dragged to death by a large number of time_wait sockets.Reference articlesHttp://www.cnblogs.com/tankxiao/archive/2012/10/10/2711777.htmlhttp://blog.csdn.net/whuslei/article/details/6667471http://molewan.blog.51cto.com/287340/114592http://www.jellythink.com/archives/705Https://wiki
The introduction of water wave texture, the early need to use a variety of filters to produce black and white watermark effect, and then color. The use of filters when the parameter settings are more important, depending on the actual picture size to be set.Final effect

. At this point, 3 handshake completed, connection established!State transitions when disconnectingBecause TCP connections are full-duplex, disconnecting is a little more hassle than establishing a connection. The client sends a FIN message to the server, requests a disconnection, and its status changes to Fin_wait1. After the server receives the fin, an ACK occurs to the client, and the server state changes to close_wait. When the client receives an ACK, it enters the fin_wait2 state. The conne
As the saying goes, the rainbow after the storm, but after the financial turmoil, the rainbow in all walks of life need their own to create. In the economic stability but lack of growth momentum of the situation, each industry is a surprise, want to in the post-crisis era to create a better future for themselves, so as to keep pace with the times to maintain steady growth. In the face of such an economic environment, the domain name industry has also been frequent moves, set off a wave of
With the popularity of netbooks in Europe and the United States, a large number of manufacturers before the production of cottage machines began to switch to the cottage, more constantly have thousand-yuan netbook news to the newspaper, to the old Yao to the whole industry understanding, domestic CPU 2009 difficult to overturn waves.

In fact, any point on the wate
This tutorial introduces the high waves and beautiful mermaid methods in the crystal ball produced by PhotoShop to a friend of PHP chinnet. The results produced by this tutorial are very beautiful and difficult, we recommend that you go to the PHP Chinese web. if you like it, let's take a look at it. this tutorial introduces a friend of PHP Chinese web to how PhotoShop creates high waves and beautiful merma
to be sent or actively sending data. However, the client has already entered the closed status, and the server will remain waiting, which wastes the server's connection resources. Four Waves The release of a TCP connection takes four steps. Therefore, it is called "four waves 』.We know that the TCP connection is bidirectional, so in the four waves, the first t

PrefaceThrough this chapter, can know in fact three times handshake and four waves actually really good simple, through this chapter of learning, I believe you will also think, in the future do not need to hear others ask three times the process of shaking hands and oneself a face Meng forced, think someone good dick, in fact, he knows you do not understand, only this, do not understand to learn. Learn you will feel that in fact, there is no serious,

Specifically as follows:This is based on JavaScript implementation of the piano button waves picture arrangement effect, the mouse in the picture list move, the current picture highlighted, to this as the basis, the surrounding picture gradually become small, so have a finger across the piano k
A lot of new Java projects need to be online recently, but a lot of Java related libraries are not very familiar with, the project met with a great deal of resistance, survived for several days of the night. Now the work is basically completed, so I intend to summarize the relevant Java tools library, in the future need to help you, good in Java under the ocean, the waves . (Want to be like a pony in a movie programmer J)The
removal of TCP connections requires sending four packets, so called four waves (Four-way handshake). Either the client or the server can initiate a wave gesture, and in socket programming, any party performs a close () operation to generate a wave. See Wireshark Grab bag, the measured capture results are not strictly according to the wave timing. I reckon the time interval is too short to cause. 1. Establish Connection Agreement (three handshake)(
of initiating active shutdown, the specific process such as:Figure 4 waving at the same timeProcess and status in the already very clear, here no longer repeat, you can refer to the previous four waves wave resolution steps.Iv. notesOn the three-time handshake and four waves usually have a typical face test, which is presented for the needs of the XDJM for reference:(1) What is the three-time handshake or
