How does python view system network traffic information and python network traffic? Preface The traffic information can be directly stored in/proc/net/devTo view, the program implemented by the author uses the command: python net.py interface WhereinterfaceIt is the name of the network card, which network card is used, and which network card is available on the c

. Always feel this logic, not too right. I also really hate app brush companies, but from which point of view to criticize and punish them, it really deserves more discussion of laws and regulations.Do not talk about ethics and regulations, talk about technology, I think technically can follow the following model to deal with false traffic, especially mobile side.Hardware: mobile phone has more hardware information, so through the hardware information

... If we ask for the connectivity of [L, R] City (i.e. [L, r-1] lattice, assuming that the lattice numbering starts from 1 to the left to the right), then you can use something to maintain the entire interval of the lattice, the answer is the entire interval boundary of the 4 points of connectivity .... Found that is not all very similar, that is, multiple grids and a lattice are to take the boundary of the 4 points to judge .... And [L, R-1] can be combined by ... So on the line segment tree

However, I have not done this problem.This problem is a classical model for maintaining the connectivity of line-segment trees.One node of our segment tree represents the connectivity of an interval, with 6 bool values representing the connectivity between points on the 4 corners of the interval.Then the connectivity of the whole inter

in which I point all flows ) –sum ( the Nether Stream where I point all flows out )Assuming that the mi is greater than 0and that the point must also flow out of the free stream to mi , then we connect a single mi edge from the source point to that point. Assuming that Mi is less than 0, this point must also flow in The free stream of MI. So we'll go from that point to the edge of a Mi to the meeting point. Suppose the maximum flow of the s->t is calculated to see if the full stream ( The n
