architecture," and today it is about operating system-related topics. C + + cross-platform development and OS-related trivia very much, so today will be long-winded, please yours faithfully crossing forgive:-)In order not to bypass the mouth, the following Linux and a variety of Unix collectively known as POSIX system.File System (filesystem hereinafter referred to as FS)New to the beginning of cross-platform development, most of the novice will enco

One afternoon to see a lot of hardware-level knowledge, too much to see too quickly easy to forget. Then write down the reading notes on the blog.About hardwarePC Architecture Interface DevicesThe motherboard chipset is the "North-South Bridge" collectively, the north-south Bridge to control the communication between the components　　 North Bridge connected faster components (CPU, graphics, memory), known as the system bus　　 South Bridge connection s

I. Introduction of FlumeFlume, as a real-time log collection system developed by Cloudera, has been recognized and widely used by the industry. The initial release version of Flume is now collectively known as Flume OG (original Generation), which belongs to Cloudera.But with the expansion of the FLume function, FLume og code engineering bloated, the core component design is unreasonable, the core configuration is not standard and other shortcomings e

What is the difference between UI and UX? For small and medium-sized business children's shoes, may feel that these two posts is a post ah, there is no difference ah, they are collectively referred to as design or UI, but they really no difference? If it doesn't make any difference, why do big companies set up UI posts and UX posts? The following is the UI and UX, the difference between the job responsibilities, for everyone to introduce the details o

. According to the monitoring data of the global non-PE samples by Golden Hill poison PA Safety Laboratory, the current confusion about JScript scripts is changed as follows:Under the characteristics of different confusing operation, the actual sample case is analyzed and summarized, and finally, the method of detection is given for different confusion ways.Scripting confusionScript confusion in a variety of ways, often using coding, encryption, deformation, segmentation and other operations

original typeFirst, there are a few terms. A class or interface whose declaration has one or more type parameters (type parameters), which is referred to as a generic class or generic interface [jls,8.1.2,9.1.2]. For example, the list interface has a single type parameter E, which represents its element type. The full name of the interface is List (read as a list of "E"), but people often call it list. Generic classes and interfaces are collectively

Originally wanted to write a blog about the Java class loading mechanism, later found that the subject is a bit large, which involves too much detail, a blog post, words I am afraid can not speak clearly, so decided from the whole to the local, first to talk about the life cycle of class, from the overall grasp a class from "Born" to "apoptosis" process, It involves the class loading, using, unloading and so on each stage, has the whole cognition, then thorough detail and unifies the concrete ex

[Previous] In addition to introducing the IOC through custom controllerfactory, it is possible to use the default defaultcontrollerfactory to make an IOC based controller active. The main way is to customize Controlleractivator and Dependencyresolver. Iv. controlleractivator v.s. dependencyresolver As the following code fragment shows, Defaultcontrollerfactory has two constructor overloads, one with a parameter of type Icontrolleractivator interface. We will implement the type of the interface
