Following the article http://blog.csdn.net/simonchi/article/details/41722511, I think it is necessary to give a detailed talk about the TCP three handshake and four waves of the process, to help you understand the process.First, take a look at Tcpdump crawl network packet, how to grab packet Analysis reference the link given aboveThe red box in the figure is the three-time handshake to establish the connectionFirst time: The client sends the SYN message and sets the Seq=0,Second time: The server
the road between the C Road, Ai, and bi. Ask how to rebuild the city that can rebuild the most, and let the number of cities in the reconstruction of the formation of the dictionary of the smallest problem-solving ideas: In fact, to ensure that the largest match, the smallest dictionary order. For this one point can be multiple matching problem, we can split the point into K. Then let the K-break point be connected to the point where the point should be connected when it is not demolished. Then
Hello, Kallan brother.I seem to have seen a similar example in the matplotlib example a few days ago, but that seems to be three-dimensional.After seeing your question, I went back to find it.And then I thought, the question is essentially showing the text on the figure. Should be possible with the text method.Without your data, I can only simulate it.For example: Display numbers on a curve and adjust different colors based on valuesImport NumPy as NP Import = np.linspace (0.0, 5.0, += Np.cos (
To give you illustrator software users to detailed analysis to share the plot of the complex smooth curve tutorial.

Complex smooth curve is not refers to the macroscopic shape of lines, such as a lot of bumps, depressions, transitions and mutations, and so on, it is a macroscopic view of a whole curve, smooth refers to the curve transition smooth, whether the rapid or soft transition, are smooth.

In R, plotting is done by specifying the col parameter of the plotting function, for example, par (BG = "cornsilk") # given the plotting background color x = rnorm (1000) y = cumsum (x) plot (Y, type = "L", Col = "red", xlab = "X Series ")
Col can assign Vectors
Method 1:
Use the color name, such as "Red", "green", and "Black "...
There are 657 colors available in R, which can be viewed and used through the colors () function.
CL = colors ()
X = r
A good enumeration + simulated question. Change thinking perspective

However, a careful analysis shows that each vertex is traversed in all eight directions 100x100x100 ^ 8. X points, select from 8 when each point goes, TLE
So we changed it to another angle:
Take the compliant point as the turning point and walk in two vertical directions to find the farthest distance. In this way, you only need to know the length of each vertex and combine the corresponding values.

Then the n × n matrix follows.
The input ends with n = 0.

Preliminary Exploration of Cytoscape plot and Preliminary Exploration of cytoscape
Cytoscape is a js plug-in for network diagrams. It is easy to use and powerful. This is its website: Click to open the linkTo use this function, you need to import two files: one is a js file and the other is a css file. Download from the official website.
Here, a function is implemented, that is, retrieving data from the background database, then returning to the front
Android: Let's talk about the Toast plot (BASICS) and androidtoast in Android apps.
Preface
Toast, a pretty girl who has been fascinated by thousands of software developers, especially android Developers, has always appeared frequently in various star applications. Toast is a magic horse ~ I heard it's a kind of toast. can you eat it? If the phone screen is made of chocolate, I think it tastes good. Let's get down to the truth. Let's talk about the To

Java fractal plot cohe snowflake curve code sharing
The section is similar to the whole in a certain form and is called a fractal. The cohe curve is a geometric curve with a shape like snowflake. Therefore, it is also called a snowflake curve. It is one of the fractal curves, the description is as follows:
First, let's give an example:
We can see that a small cluster of broccoli is a branch of the entire flower cluster, and they have their own shape
. The incoming edges are reversed, OK, and inbound = outbound. The same is true for the entry point. So what should I do if it is not connected to S or t? The connection condition with S is "out"> "in", and "T" is "in"> "out", so this is neither a point connected with s nor T, as early as the beginning, = has been satisfied. In the network flow process, these points are "intermediate points ". We know that the traffic at the intermediate point is not allowed to accumulate. In this way, the incom
