pinnacle surveyors

cooperative measurement and non cooperative measurement according to the knowledge of the surveyors, and the protocols used in the measurement are divided into the measurement based on BGPOSPF and other routing protocols, Based on the measurement of TCP/IP network and Transport layer protocol and the measurement of Application layer protocol based on SNMP,DNS, the measurement can be divided into topological measurement and performance measurement.

like a life link, through the top and bottom, poetic poetry with the lunar cycle of the birth and fall and twists and turns. The month went through the process of rising--hanging--West inclined--falling. In the moon, the river, sand, sky, wilderness, Maple, Huaring, flying Frost, White sands, boat, high-rise, mirror, Anvil, long fly of the goose, diving into the fish dragon, sleepless women and wandering wandering, composed of a complete poetry image, showing a full of life philosophy and life

: Redis is an example of single-threaded asynchronous network programming Nginx is the pinnacle of multi-process network programming, modular Although memcached is C + +, the pinnacle of C style, multithreaded network programming Data Structures Databases: SQLite, a paradigm of data theory.

software. It is dedicated to keeping the system design as simple, clean and expressive as possible at all times.Here is a copy of the case in the book to illustrate the difference between poor design and agile design:Scene: A radio app, the original design boss only need to put music on the good, this demand is very simple, the first version of the design is as follows:Well, it looks pretty good, and you're going to get a raise for this great programming skill. Marry mating embark on the

. Create simpler and more secure modules with a non-global environmentIf you have just reached the pinnacle of our high (AI) Zhe (Teng) crowd, you are naïve.The pinnacle is to get beyond, remember our non-global environment? That's the setfenv function. Let's take a look at the following code:Local M == = m;setfenv (1, M); function play () print (" Then , start "); Endfunction quit () print (" you go,

the relationship between NP and P-type problems.Obviously, all P-Class problems are NP -related. That is, to solve a problem polynomial, it is necessary to be able to polynomial to verify the solution of a problem-since the positive solution has come out, verify that any given solution can only be compared. The point is that people want to know if all NP problems are P-type. We can use the view of the collection again to illustrate. If all P-class problems are classified as a set P, and all NP

that time, the network has emerged, Novell production network operating system occupies the network dominance, but the emergence of NT, Novell's life has come to an end.Jobs, who were driven out of Apple, did not stop his pace, After Jobs left Apple, Pixar, which now has the pinnacle of the three-dimensional animation, has been forced to recall jobs to save Apple's increasingly decadent landscape as Apple's competition for Microsoft has gradually dec

that the most difficult problem in informatics-the "NP problem"-is actually exploring the relationship between NP and P-type problems.Obviously, all P-class problems are NP-related. That is, to solve a problem polynomial, it is necessary to be able to polynomial to verify the solution of a problem-since the positive solution has come out, verify that any given solution can only be compared.

If all P-class problems are classified as a set P, and all NP problems are classified into another set NP, then it is obvious that p b

comes too suddenly!" To the pinnacle of life @ According to Miyan: Today with the source of China's pen, signed a contract. Looking forward to 2015 new beginnings a small compilation of this seniority is still shallow ah, or the first time to see the open source pen, but open-source mug, open-source underwear and so can bring you good luck, no bugs, but also with you to the pinnacle of life! If not satisf

do not expect a polynomial-level algorithm to solve a problem in which a solution is not available. It is believed that readers soon understand that the most difficult problem in informatics"NP problem" is actually discussing the relationship between NP problem and P-type problem.。 Obviously, all P-class problems are NP-related. In other words, to solve a problem in polynomial way, it is necessary to validate the solution of a problem by polynomial-Since the positive solution is all out, verify

For love, for love, but also for greater fraternity for greater fraternity, the melancholy man once again faced with the lover death, sacrifice himself.And precisely because of this movie, because of this movie,, let Casablanca become romantic and poignant synonymous with poignant, countless called "Casablanca Casablanca" "Café also springing up after Chunsun, and no matter how small its shop and no matter h

A lot of friends ask me, want to know more about the Linux operating system but can not find the starting pointThe advice I give you is: So C is an essential skill to learn Linux in depth, you can see Rectification's green Book, although a lot of black people, but the entrance is sufficient. > The next step is to read more about the C code of the excellent Linux project. On the 4th, the answer to a question on the understanding, harvest a lot of praise, hop

A lot of friends ask me, want to know more about the Linux operating system but can not find the starting point learn C,c language and *uix is a piece of growth, so the Linux operating system API is described in C language. So C is an essential skill in learning Linux in depth. , we can see the rectification of the Green Book introduction, although black people a lot, but the entry is enough. On the 4th, I answered a problem , the unexpected

servers. In this way, hardware investment and management and maintenance costs are reduced. 6. software programmers, APS programmers, and web designers A program compiled by a programmer needs to run in multiple environments and multiple systems. In the past, programmers can only find multiple computers or install different environments on one computer repeatedly (single-host environment, network environment, different IE versions, and other issues, database environment, etc) or multiple syst

The Internet will eventually become an organizational structure highly similar to the human brain. We call it the Internet virtual brain. After creating a panoramic view of the Internet virtual brain, we will view the physical sensory system, Visual System, and, auditory System. We will introduce them together with the motor neural system. The Internet body sensory neural system sensors are mainly composed of electronic sensors that can detect and feel external signals, physical conditions (suc

simplified situation that we will introduce later. After the reader is familiar with the simple factory model introduced in this section, it is not difficult to master the factory method model.Q At the beginning of this section, it is not said that the factory mode is to change ...... is the class instantiated? Why is the new operator still used in the specific implementation? There are three fruit classes in the small orchard system in this section. Why is there only one product class in Figu

="/usr/lib/libtcmalloc.so" Ld_preload is tricky, and we do not recommend this method very much. Tcmalloc also contains a heap checkerAnd a heap surveyor.. If you want to link the tcmalloc version that does not contain the heap surveyors and the checker (for example, to reduce the size of static binary files), you can accesslibtcmalloc_minimal. Tcmalloc assigns a local cache for each thread. Small allocation can be satisfied directly by the local cache
