the App UI interface shows the logical principle of the screen:
When Activitythread receives AMS to send a start activity, it creates the specified Activity object. The activity creates the Phonewindow class-decorview class-Create the corresponding view or ViewGroup. Once created, the activity needs to display the created interface to the screen, then call the WindowManag

1. Overview
Linux adopts a ring buffer kernel with a size of __log_buf_len bytes to store system logs, where __log_buf_len equals ( 1
The kernel log buffer is accessible to reading from userspace by/proc/kmsg. /proc/kmsg behaves more or less like a FIFO and blocks until new messages. Please note that the reading from/proc/kmsg consumes the messages in the ring buffer so they is available for other progr

The first step is to create an account that is specific to Git's warehouse, which is also easy to manage. You can refer to the Linux New User command for this article.
#新建一个git用户组sudo groupadd git#新建一个git用户, create a directory, and prevent shell logins from being added to the GIT user group
sudo useradd git-m-s/sbin/nologin-d/home/git-g git
The second step is to create a new git warehouse, called Git bare repository, which is the repository for git.
$ mkdir Repo.git$ chown

Linux and Mac OS X lyx Setup requires that you install a Tex/latex version of the platform separately. Some Linux platforms require you to install additional packages to access a specific LaTeX macro package, such as an AMS Tex package used by a publication from American Mathematical Society.
