capitalization specification to name variables that do not change in the program's life cycle. There is another formula for full capitalization: The global variable name is all capitalized . Another way to simulate functionality using a specification is private members, and developers find it easier to use only an underscore prefix to represent a private property or method. The following are some common _private specifications:

Overview of the two basic specificationsDTS (device tree syntax, another way of saying device tree source) is a plant-based file that is used in text format for readability and modification. The DTC (device tree compiler) is a small tool that is responsible for converting DTS into a DTB (device tree blob). DTB is a binary form of DTS for use by machines. In use, we first modify the DTS file according to the hardware, and then at compile time through the DTC tool to convert the DTS file to a DTB

1. Strictly use indentation to embody the logical affiliation of the code.Python's indentation of the code is a hard requirement, which must always be noted. If the indentation of a piece of code is incorrect, then the whole program is wrong, either the syntax error cannot be executed, or the logic error results in the error, and checking for such an error can take a lot of time.2. Each import statement imports only one module, preferably in the order of standard libraries, extension libraries,

First, the Golden law: The always follows the same set of coding specifications. No matter how many people join the same project , make sure that each line of code is written as if it were the same person. html section Span style= "font-family: Microsoft Jacob Black;" > syntax Use two spaces instead of tabs (tab)- This is the only way to ensure consistent presentation in all environments. Nested elements

Decided to start the Python road, using spare time, for more in-depth study of Python. Programming languages are not art, but work or tools, so it is necessary to organize and follow a set of coding specifications. So this afternoon I made a copy according to Pep 8, and I'll follow this code, and I'll keep updating it.PEP8 Python Coding SpecificationA code orchestration1 indent. Indentation of 4 spaces (the editor can do this), no tap, no mix of taps

Let's say you touch something new. You may feel at a loss, but assuming it's the old thing, is it hard for you to learn? First,ODBC, our old friend. the ODBC (Open database Connectivity) is the interface specification for Microsoft Corporation and the database. Essence Point:1.ODBC , set up a set of specifications and provide a set of standards for access to the database API , standard application Data interface. 2.ODBC is to use C language Implementa

I think we all know what ODBC is? ODBC (opendatabaseconnectivity, open Database interconnect) is an integral part of the database in the Microsoft Open Service Architecture (wosa,windowsopenservicesarchitecture), which sets up a set of specifications and provides a set of standard APIs (application programming interfaces) for database access.JDBC (Java Data Base Connectivity,java database connection) is a Java API for executing SQL statements that pro

When crossing the road, I suddenly noticed the traffic lights, and the recent new traffic rules were also in full swing, So I thought about the "design specifications. When it comes to design specifications, many people think it is a very virtual and not pragmatic performance project. Many enterprises design specifications for design

The recent launch of the In-app billing IAB built-in billing API for Google Play found that a more annoying problem was that the application had to be formally signed while testing, and that the default Eclipse ADT Debug run was using a temporary generated debug certificate. The default is C:\Users\XXX\. Android\debug. KeyStore. So every time you debug built-in billing you have to use ADT's export signed application package to play with formally signed packages, more cumbersome. ADT was later fo

The MAC Address Table size of a device reflects the maximum number of nodes that can be supported by the device. 14. Maximum number of power supplies. In general, the core equipment provides a redundant power supply, after a power failure, the other power supply can continue to power, does not affect the normal operation of the equipment. When there are multiple power supplies, pay atten

Programming | coding | who can write code! A few months of programming experience allows you to write "Running applications." Make it easy to run, but coding in the most efficient way requires more effort! You know, most programmers are writing "run code," not "efficient code." We mentioned earlier in this guide course, do you want to be your company's "Most distinguished professional"? Writing "Efficient Code" is an art that you must learn and practise. Naming conventions and

model design is the IDEF1X method, which is a semantic modeling technique applied to the semantic data model by the entity-contact method, which is used to establish the system Information model. The steps to create an E-R model using the IDEF1X method are as follows: 2.1 The 0th step--Initialization of the project The task at this stage is to start with the objective description and scope description, to identify the modeling objectives, to develop the modeling plan, to organize the modeling t
