A Preliminary Study on WCF-16: Basic knowledge of WCF data protocols, wcf-16Data protocols
"Data agreement" is a formal agreement between the service and the client, used to describe the data to be exchanged in an abstract way. That is to say, for communication, the client and service do not have to share the same type, but only need to share the same data protocol. Data protocols precisely define the parameters or return values that need to be ser
Data Structure BASICS (16) and data structure basics 16Basic Terms of the tree
1. node: {Data Element + several branches pointing to the subtree}
2. node degree: number of branches (number of sub-trees)
3. Tree degree: the maximum degree of all nodes in the tree
4. leaf node: zero degree Node
5. branch nodes: nodes with a degree greater than zero (including the root and intermediate nodes)
6. (from the root to the node) path: consists of the branches
English Name: Hex number system is a representation of the data in the computer. is not the same as our daily decimal notation. It is made up of 0-9,a-f. The corresponding relationship with the 10 binary is: 0-9 corresponds to 0-9; A-f corresponds to 10-15; The number of N-ary can be expressed in 0---(N-1) for more than 9 letters A-F. The 10-in-32 representation of the 16 system is: 20 16 into the 32 into 1
Admittedly, this time the title is a bit long. The title is written in such detail, mainly for the search engine can accurately put the need to understand the GCC generation 16 real-mode code method of the friend brought to my blog. Let's start with the background and write 16-bit code that runs in x86 real mode, which is really a bit retro, so there's less data to find. To run the x86 real-mode program, I
Binary conversion has always been a headache for beginners, the following is a simple list of how each of the binary is converted.# print (' 2-->8: ', Oct (int (' 0b1010 ', 2)) # 2-10-8# print (' 2-->10: ', int (' 0b1010 ', 2)) # 2-10# print (' 2-- GT;16: ', Hex (int (' 0b1010 ', 2)) # 2-10-16# print (' 8-->2: ', Bin (int (' 0o12 ', 8)) # 8-10-2# print (' 8-->10: ', int (' 0o12 ', 8)
input, and the resulting feature map size is 28*28*6. The C1 has 156 parameters that can be trained (each filter 5*5=25 a unit parameter and a bias parameter, altogether 6 filters, a total of (5*5+1) *6=156 parameters), a total of 156* (28*28) =122,304 a connection.2, S2 layer is a lower sampling layer (average pool layer) (using the principle of local correlation of images, sub-sampling of the image, can reduce the amount of data processing and retain useful information, reduce network trainin
Common ratios
At the beginning of the information age of 195x, the most notable feature is that analog technology has turned to digital technology, graphic design has been gradually led by electronic devices from paper to media, and the granularity units have changed, but this is not so much for designers, the problem is the ratio.
Aspect ratio, which is the height ratio, only discusses the three most common categories: photography, video, and display equipment.
The common rates of photograph

According to the microprocessor (CPU) Word length classification by the microprocessor, the microcomputer is generally divided into 4-bit, 8-bit, 16-bit, 32-bit and 64-bit machine.(1) 4-bit microcomputer; 4-bit word-length microprocessor is a CPU, its data bus width is 4 bits, and one byte is divided two times to transmit or process. The 4-bit machine instruction system is simple, the Operation
Currently centos/red Hat (RHEL) 6.2 officially comes with the MySQL version for 5.1,mysql5.5 has come out.The improvements are not only made in several ways compared to mysql5.1,mysql5.5:
The performance has improved a lot.
Change the default storage engine to InnoDB
CPU multi-core processing performance improvement
Enhanced replication, new semi-synchronous replication
Enhanced table partitioning Capabilities

In Java, byte is used in binary notation to occupy 8 bits, and we know that each character of the 16 binary needs to be represented by 4-bit bits (23 + 22 + 21 + 20 = 15), so we can convert each byte to two corresponding 16 characters. That is, the high 4 bits of byte and the lower 4 bits are converted to the corresponding
CRC-16 is used to write a program not long ago, but looking for to find only in Uddf found a Delphi CRC-32 program code, but also use look-up table method, although the speed of look-up table method, but 256 32-bit data I suspect there may be input errors, people are not so relieved, and I do not know this How the table was calculated. Then I found a section about CRC in a notebook two years ago, also do not know where to copy from, fortunately there
When flash is connected to the CPU, according to different data width, such as 16-bit nor flash (A0-A19), the processor address line to (A1-A20) shift left to 1. Why is it one-digit?
From the perspective of software and CPU, an address corresponds to one byte, which is 8-bit data. This is for sure. Do not doubt this.
For a specific device, its bit width is certain. The so-called Bit Width refers to "the smallest data unit during read/write operations"

Junction and right Outer junction. The only difference between them is the order of the tables that are associated with each other. In other words, a left outer join can be converted to a right outer junction by reversing the order of the tables in the From or WHERE clause.9. Differences between internal and external linkagesGenerally speaking, the left connection, outer connection refers to the left outer connection, right outside the connection. Do a simple test, you see. First say lef

The result of the conversion is a decimal number.>>> int (' 0xf ', 16)15Binary to Decimal>>> int (' 10100111110 ', 2)1342Octal to Decimal>>> Int (' 17 ', 8)15You can actually see that the int () function is used regardless of the number of decimal numbers that are converted in
Summary: in the process of using a Linux server, there are 16 commands to help you get a complete picture of your server's health. If you can master these commands skillfully, it is not far from being a professional Linux system administrator!In different Linux distributions, there will be different GUI programs to display various system information, such as the SUSE Linux distribution, there is a very good graphical configuration and management Tools
Then the screenshot of Outlook for Mac 16 leaks, and Cnbeta also brings up the roadmap and detailed updates for the entire product of office for Mac 16. This leaked data shows that next-generation office for MAC 16 will launch a beta test by the end of the year, and will be released by the first half of next year.

The stupidest way to do this is to first select the largest number from 16 numbers and then pick the maximum number from the remaining 15 numbers to get the answer, so you need to 15+14=29 the comparison.Since this question requires that the second largest number be found within 20 comparisons, we would like to have a simple method.Assuming that the largest of the 16 numbers is a, the second largest is B.Fi
