This article is about some notes and Experiences after reading Charles Wyke-Smit's "CSS design guide" over the past few days. I seem to be getting started with web design when I was a freshman, because it is not a computer Major, all of them are self-taught. I remember
4 stages of getting Started with Linux systems for IT Technology Learning Guide (pure Dry ribbon diagram)60% of the world's people are using Linux. Almost no one is "in favor" of the Linux system, and many of the services we enjoy (including Web services, chat services, and so on) are almost always powered by Linux systems, with more than 2 billion people carryin

In this article, we will explore the use of Python programming language tools to retrieve various information about Linux systems. Walk you.
Which Python version?
When I mentioned Python, I was referring to CPython 2 (exactly 2.7). I will explicitly remind those same code that it is not working on CPython 3 (3.3) and provide an alternative code that explains the differences. Make sure you have CPython inst
Linux Kernel 2.1.53 The TCP/IP stack is open and closed with a specific response to a particular packet, and an attacker can use this feature for a secret scan of the port.
Some CGI programs such as Dbman (DB.CGI) have vulnerabilities that allow attackers to see some of the system's environment variables, allowing attackers to gain some useful information about the system.
Although the above categories include the vast majority of vulnerab
It is written in C ++ and modular design. It can be embedded into programs written in any language, or directly called in various popular scripts. All operations are encapsulated in the module. You only need to call the corresponding export function externally. C #, C ++ applications have successfully used this module to develop various information collection systems.
The entire system includes the follow

13. Tools for processing target files14. Summary Links can be done at compile time by a static compiler, or by a dynamic linker at load time and at run time. The linker processes the binary file that becomes the target file, and it has three different forms: relocatable, executable, and shared. The relocatable target file is merged into an executable target file by a static linker, which can be loaded into memory and executed. Shared destination files (shared libraries) are linked an
information about the field declaration or the field name.3. Union: Allows you to reference an object in multiple types, using different fields to refer to the same memory block. The total size of a union equals the size of its maximum field. Unions can also be used to access bit patterns for different data types.4. Data alignment: A type object must be a multiple of a K value (usually 2,4 , or 8). This alignment restriction simplifies the hardware d

Choose a color scheme
Sometimes color matching is a momentary flash of light, but more often, it has a more systematic way to match.
Determine the purpose
Before starting the design, determine the purpose of the design. Ask yourself these questions before you start:
What information do you want to communicate with your design?
What is the purpose of your design? To provide information?
Recently, we've been working on Docker and Kubernetes, both in the go language, in order to get a deeper understanding of Docker and kubernetes, and to learn about the go language.In order to learn in detail, a directory is listed here, will be constantly updated
