- How to create and present presentations from the Linux command line
- In the Linux world, there are several different ways you can choose to give a presentation. For example, Impress.js has a large number of multimedia displays and excellent visual impact, Beamer is specially provided for LaTex users, and so on. And if you're looking for an easy way to create and display text presentations, mdp can help you achieve it. What is MDP? mdp is the next ncurses-based command line demonstration tool for Linux. What I like about mdp is its support for markdown, which makes it easy for me to create slideshows in the familiar markdown format. Naturally, it can also easily publish slideshows in HTML format. Another benefit is that it supports UTF-8 character encoding,

- Win+linux dual system installation
- 1. The step of installing the system U disk with UltraISO should not go into too much detail. Whether you are installing a windows or ubuntu system, making a system U disk is necessary. The blogger is using the system USB disk installed by UltralSO. You must download the Ubuntu image before installation. You can choose which version you want according to your needs. 2. Set the U disk to boot. Enter the BIOS to set the U disk to boot. This step is also a necessary step to install Win10. Different brands have different setting methods. You should set it according to your own model. After setting, the U disk can be automatically started after plugging in the system disk. 3. Win10 creates a disk partition. Win+X enters the disk partition directory and sets the disk partition prepared for the Linux system.

- Old Boy Linux Issue 23 A must-read for operation and maintenance personnel: How to increase your salary in Beijing, Shanghai, Guangzhou and Shenzhen?
- If you want to make more money, you need to cultivate your abilities above the knees (from the space of the old boy teacher). Students living in Beijing, Shanghai, Guangzhou and Shenzhen who are not satisfied with their wages should take a closer look! It’s the Spring Festival. I write this article to share with you. I wish you a happy Spring Festival! Opening: Operation and maintenance personnel, please don’t belittle yourself! Some operation and maintenance personnel are in operation and maintenance positions themselves, and they really belittle the operation and maintenance position and think that development is awesome. Of course, that is just a "siege", linux system image download, dear! Operations and maintenance are the same as development. They are both IT jobs. Although pure operation and maintenance are similar to pure development, they are both quite miserable. Development is mostly more miserable. You work overtime very late to get the project online quickly. Sometimes you don’t see anyone in closed development for a month. The 23rd issue of Renlaoboylinux has been launched and bugs and functions have been improved every day!

- Nginx+Tomcat deployment operation of Angular+javaweb project
- Initially, I used ngbuild-prod-aot to compile and package. Note here that since it is now officially built-in, you only need to enter ngbuild–prod when packaging. Here you can compare it with the size of my project: ngbuild: 8,348,761 bytes ngbuild–aot: 9,232,405 bytes ngbuild–prod: 1,839,811 bytes ngbuild–prod–aot: 1,839,811 bytes Finally, it can be seen that ngbuild–prod can be completed. Minimum packaging for productization. I don’t understand something here. The pre-compiled build is larger than the regular build. I hope it will be bigger.

- Solutions to Linux subsystem errors under Win10
- In order to better test Linux applications, many users will install the Linux subsystem on Windows 10 system computers. However, a friend recently reported that he encountered an error message of 0x80070057 when turning on the Linux subsystem function. What should I do? Next, the editor of PConline will share with you the solution. The details are as follows: 1. This error is because win10 has released a new version, but the computer's win10 has not yet been upgraded to the latest version. When it failed like mine, the latest released version number was 1703, but the current version was not caused by 1703; 2. We can press [Win+I] to open the settings, and then click [System] > [About] to view the current version.

- Linux kernel auxiliary tool function inventory: analysis and application of container_of macro
- Scan and pay attention to learn embedded, learn together, and grow together. The Linux kernel is an independent software. He does not use any C language library. He has implemented many tools and auxiliary tools by himself. This series of articles will take stock of some auxiliary tool functions provided by the kernel. When compiling a driver program for the Linux driver kernel, we can use the tool functions provided by the kernel to easily achieve the target function. The macro definition of macro container_of is very famous, and many articles have analyzed it, but this macro is often seen in the kernel and drivers. The function of this macro is to derive the address of the structure through the address of the structure members and the structure type. li under the toolsincludelinuxkernel.h file of the linux source code

- Explore the basics of Linux: the mysteries of hard drives and partitioning techniques
- 1. Linux basic knowledge points Hard disk drive is a medium that can store a large amount of information resources. The hard drive we usually see is a square and heavy iron box. Although the hard drive is round, after adding some control circuits, it is designed into a round case for easy portability. And the hard disk is really round. I'm not going to lie to you. How else would it be called a disk? Second, what you need to know is that hard drives can be partitioned. You can partition a hard disk into multiple partitions and exit without saving under Linux. It seems that a partition is both a ranking and a tense. What are the partitions called rankings? Today's hard drives are getting larger and larger, storing more and more resources. In order to more reasonably manage the use of hard disk resources and more effectively improve query speed and access quality, we can define hard disks as many

- What are pipes and named pipes used for in Linux? One article will help you understand
- The editor would like to share with you the uses of pipelines and named pipes in Linux.

There is a lot to gain, let’s find out together below! In Linux, pipe allows you to send the output of one command to another command. Pipes, as their name suggests, redirect the standard output, input, and errors of one process to another process for further processing. The sentence pattern of the "pipeline" (or "unnamed pipeline") command is to add the | character between the two commands: Command-1|Command-2
