Recently busy studying Glusterfs, was going to write a few blog weekend, but due to debug some of the new features of Glusterfs used a whole day, and a day to accompany the wife of adults to go shopping! This evening after browsing the microblogging discovery time has come to blog one, this blog content is mainly in the previous period of time to study the Thrift code generator of the source of detailed analysis, no specific analysis of parsing, becau
Q: A boot CPU like a generator is very loud, and then the main version of the interface after the hint: CPU fan errow! Press F1 to enter the next step, but will appear to prompt you in Safe mode, the last normal configuration or the normal start of the interface, and then choose a can sometimes go in, sometimes can not go in, but anyway the CPU still very loud, this how?

This immediately aroused my interest. Serial numbers (serial number) are widely used in the program, and the generation rules are different. (for example, our company's membership card number rules inside there is a "card number encountered 4 Skip" option. I went to Google a simple search, found that a

The building has recently been fascinated by random algorithms, and random numbers are the basis for generating random algorithms. Building ready to use linear congruential (Linear congruential method) to generate a random sequence, this method needs to set four non-negative in
-increase field or sequence). We can use Generator-class=native's primary key generation method on the primary key generation mechanism provided by the database. It is worth noting, however, that some databases provide a primary key generation mechanism that is not necessarily the most efficient, and that large amounts of concurrent insert data can cause interlocking between tables. The primary key generation mechanism provided by the database is ofte

Many years ago used Li Tianping predecessors, their own change, and then the teacher Li did move soft, not to the source code, modification is not very convenient. Plus I need to go to the Java direction now, so I decided to do it myself. So far it has taken one weeks to look at the current results.The last is the code engineering file, developed in C #, the IDE is VS2010To achieve maximum template freedom, a proprietary template syntax is designed. Based on C #, but has been made as simple as p
program, except for the local lambda function.GeneratorThe generator originates from the iterator, and the role of the iterator is to invoke next () to get the next element, if we want the iteration to generate the next value in some way and return to the next () call. This is one of the motivations for developing a birth generator.The generator is a function with a yield statement. A function or subroutin

Separates the construction and representation of complex objects so that different representations can be created during the same construction process. Note the following points.
(1) Construction and representation separation: indicates the structure of the generator mode. The construction process is encapsulated in the navigator, And the generator is responsible for implementing the s
1 What the generator function meansA generator is a function that returns an object that can be iterated, and it is a special iterator, but the level of abstraction of the iterator is higher and more complex requires many methods to be implemented. The generator is simple to use compared to iterators. 2 How generators are created 2.1

To get a deeper understanding and use of C #, we started this series of technical lectures on the "C # Discovery Tour". Given that most of you are in the Web database development, and the so-called discovery is found that we are unfamiliar with the field, so this series of lectures will be C # in the Web database development outside the application. The main content of the current planning is graphic development and XML development, and plans to organize a number of courses. In the next C # Disc

The Hibernate primary key generator is used to generate the primary key for data table records. There are several common primary key generation methods.Key GeneratorPrimary key generator:First, we will introduce several common primary key generators:1) IncrementIncrement: generates an auto-increment primary key for long, short, or Int data columns.The primary key increments in numerical order. The implementation mechanism of this method is to maintain
This article mainly introduces what is a generator and how to use it. the following example shows how to use it.
What is a generator?
A generator is a function that contains the special keyword yield. When called, the generator function returns a generator. You can use the s
Python BASICS (14): variable scope and generator, 2015 python
Variable ScopeThe identifier's scope is defined as its declared applicability, or the variable visibility we call it. That is, we can access a specific identifier in the part of the program.Global variables and local variablesVariables defined in a function have local scopes, and the most advanced variables in a module have global scopes.A feature of global variables is that they will survi
