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.

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.

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.
