+
+```bash
+rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
+```
+
+Your system is prepared for the PHP installation from yum repositories. Use one of the following commands to install PHP 7.3 or PHP 7.2 or PHP 7.1 on your system based on your requirements.
+
+```bash
+yum --enablerepo=remi-php73 install php
+yum --enablerepo=remi-php72 install php

+# dotnet 调用算法方案
+
+## 1. Python 开发算法内核
+
+### 1.1 跨服务调用
+
+#### 方案说明
+
+将 Python 算法封装为服务，提供 HTTP 接口，dotnet 作为客户端调用服务。
+
+#### 优点 & 缺点
+
+优点
+
+- 客户机不需要有较高的配置，也不需要安装 Python 环境，服务端可采用 Linux，配置 cuda 等 GPU 计算环境，服务端一直处于热部署状态，性能较好；
+- 通过联网对客户有更好的控制；
+- 软件架构分为客户端和服务端，开发成本低，各端定位问题比较简单；
+- 保密性好
+
+缺点
+
+- 架构较复杂，需要客户端联网才能使用；
+- 需要考虑服务端成本；
+
+### 1.2 封装为动态链接库
+
+#### 方案说明
+
+将 Python 功能封装为 dll 提供给 C# 调用
+
+#### 优点 & 缺点
+
+优点
+
+- 客户端不需要联网，使用比较方便
+- Python 开发成本较低
+
+缺点
+
+- Python 自带包里的方法封装为 dll 是可行的，但对于依赖大量通过 pip 安装的包来说，是否可行需要调研，相较于上一个方案，开发成本较高；
+- 客户端软件+硬件安装较复杂，需要安装 Python 环境，甚至需要安装 cuda 驱动、配置 GPU 计算环境；
+
+### 1.3 不封装或者封装为可执行文件
+
+#### 方案说明
+
+使用 Python 开发算法内核，将源文件放在 C# 工程中，客户端配置好 Python(or Anaconda) 环境，直接调用 Python 解释器执行脚本，或者将脚本封装为 exe 调用，参考 https://github.com/Nuitka/Nuitka 将 Python 源码编译为 exe 文件。
+
+#### 优点 & 缺点
+
+优点
+
+- 开发成本低
+
+缺点
+
+- 保密性不好，客户端有可能查看到算法源代码（待定，目前调研 Blender 是用 Nuitka 封装的）
+
+## 2 C++/C# 开发算法内核
+
+#### 方案说明
+
+使用 C++/C# 开发算法内核，并封装为 dll 提供给 C# 调用。已知一个 C++ 可用的分类代码库：https://github.com/dsteinberg/libcluster
+
+#### 优点 & 缺点
+
+优点
+
+- 运行效率高
+- 难以被反编译
+
+缺点
+
+- 开发成本较高
+- C++ GPU 编程需调研
+
+## 3 Matlab 提供算法
+
+#### 方案说明
+
+使用 Matlab 开发算法内核，封装为 dll 提供给 C# 调用。
+
+#### 优点 & 缺点
+
+优点
+
+- 运行效率高
+- 难以被反编译
+- 开发成本可控
+
+缺点
+
+- GPU 开发需要调研
+- 使用 Matlab 可能需要授权

+# git 配置
+
+## 账号配置
+
+### 配置密钥
+
+按邮箱生成密钥
+
+```bash
+ssh-keygen -t rsa -f ~/.ssh/id_rsa_your_custom_name -C "your email"
+```
+
+添加密钥
+
+```bash
+ssh-add ~/.ssh/id_rsa_your_custom_name
+```
+
+编辑 `~/.ssh/config` 文件，添加如下内容：
+
+```text
+Host github.com
+    HostName github.com
+    User Your_Custom_name
+    IdentityFile ~/.ssh/id_rsa_your_custom_name
+```
+
+### 配置单用户
+
+cd 到项目的根目录，查看 git 配置：
+
+```bash
+git config --list
+```
+
+看一下 `user.name` 和 `user.email` 是否和希望上传的账号匹配，否则使用如下命令进行修改：
+
+```bash
+git config user.email "your@email.com"
+git config user.name "your name"
+```
+
+### 配置多用户
+
+File `~/.ssh/config` is also very useful when you have to work with multiple git accounts.
+
+```config
+Host github.com
+    HostName github.com
+    User git
+    IdentityFile ~/.ssh/github
+
+Host github_as_alice
+    HostName github.com
+    User git
+    IdentityFile ~/.ssh/github_alice
+
+Host github_as_bob
+    HostName github.com
+    User git
+    IdentityFile ~/.ssh/github_bob
+```
+
+Default `github.com` will work by default.
+
+For alice: replace 'git@github.com' with 'git@github\_as\_alice' when you use `git clone` or `git remote add origin`.
+
+For bob: replace 'git@github.com' with 'git@github\_as\_bob' when you use `git clone` or `git remote add origin`.
+
+## 跨平台提交代码配置
+
+在 windows 系统中设置
+
+```bash
+git config --global core.autocrlf input
+git config --global core.safecrlf true
+git config --global core.eol lf
+```
+
+## 设置编辑器
+
+```bash
+git config --global core.editor vim
+git config --global merge.tool vimdiff
+```
+
+## 编译高版本 git
+
+```bash
+yum -y install zlib-devel curl-devel openssl-devel perl cpio expat-devel gettext-devel openssl zlib autoconf tk perl-ExtUtils-MakeMaker
+```
+
+下面的命令将 git 安装到 `/usr/local/bin/` 中，可以自行设置 `--prefix` 项
+
+```bash
+cd /path/to/git/source
+./configure --prefix=/usr/local
+make
+make install

+# Archlinux Installation based on BIOS/MBR
+
+## 1 安装准备
+
+下载 archlinux 安装镜像，并刻录到 U 盘，windows 可以用 Etcher 刻录，Linux 系统可以直接用命令刻录：
+
+```bash
+dd if=archlinux.iso of=/dev/sdx bs=512k
+```
+
+## 2 进入 Live 系统
+
+安装 Archlinux 需要联网，如果是有线网并且路由器支持 DHCP，插上网线后执行 `dhcpcd` 获取 IP 地址。
+
+更新系统时间：
+
+```bash
+timedatectl set-ntp true
+```
+
+## 3 分区
+
+查看磁盘：
+
+```bash
+fdisk -l
+```
+
+选择磁盘，创建 MBR 分区，将 `sdx` 更改为自己的磁盘，如 `sda`, `sdb` ...
+
+```bash
+fdisk /dev/sdx
+```
+
+我个人习惯分三个区：`/boot`, `/`, `/home`
+
+1. 输入 `n` 创建一个新的分区，首先输入起始扇区，选择默认就好，然后输入分区大小，这里输入 `+512m` 创建引导分区;
+2. 输入 `n` 创建第二个分区，选择默认起始扇区，输入 `+20g`;
+3. 输入 `n` 创建第三个分区，选择默认起始扇区，直接回车使用默认大小;
+
+输入 `w` 将分区的改动写入磁盘，并执行格式化。注意引导分区要格式化成 FAT32 的格式。
+
+```bash
+mkfs.fat -F32 /dev/sda1
+mkfs.ext4 /dev/sda2
+mkfs.ext4 /dev/sda3
+```
+
+## 4 安装
+
+挂载分区：
+
+```bash
+mount /dev/sda2 /mnt
+mkdir /mnt/boot /mnt/home
+mount /dev/sda1 /mnt/boot
+mount /dev/sda3 /mnt/home
+```
+
+选择镜像源：
+
+```bash
+vim /etc/pacman.d/mirrorlist
+```
+
+或者手动输入（这里选择了清华的镜像）
+
+```bash
+Server = http://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch
+```
+
+接下来安装基本的组件：
+
+```bash
+pacstrap /mnt base base-devel linux-lts414 dhcpcd
+```
+
+这里选择的 linux 内核版本是 4.14 LTS 版，想安装其他版本的内核只需要改下名称（`linux`, `linux-lts`），例如 linux 表示最新版本的内核，linux-lts 表示最新版本的 LTS 版内核。这一步需要等下载完成后安装。
+
+## 5 配置
+
+### 5.1 配置 fstab
+
+执行下面的命令，生成自动挂载分区的 fstab 文件：
+
+```bash
+genfstab -L /mnt >> /mnt/etc/fstab
+```
+
+检查生成的文件是否正确：
+
+```bash
+cat /mnt/etc/fstab
+```
+
+## 5.2 配置系统
+
+```bash
+arch-chroot /mnt
+```
+
+如果系统出现问题，只要插入 U 盘启动，然后将系统根分区挂载到 `/mnt` 下，再通过命令即可进行修复。
+
+### 设置时区
+
+```bash
+ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
+hwclock --systohc
+```
+
+### 安装必须的软件包
+
+```bash
+pacman -S vim dialog wpa_supplicant ntfs-3g networkmanager
+```
+
+### 设置 locale
+
+```bash
+vim /etc/locale.gen
+```
+
+设置 `en_US.UTF-8` 然后执行 `locale-gen`。
+
+```bash
+echo "LANG=en_US.UTF-8" >> /etc/locale.conf
+echo $hostname >> /etc/hostname
+```
+
+### 设置 hosts
+
+编辑 `/etc/hosts`，加入
+
+```text
+127.0.0.1 localhost
+::1 localhost
+```
+
+### 设置 root 密码
+
+```bash
+passwd
+```
+
+### 安装 intel-ucode
+
+非 intel CPU 跳过
+
+```bash
+pacman -S intel-ucode
+```
+
+### 配置 boot
+
+```bash
+pacman -S os-prober ntfs-3g grub
+```
+
+部署 grub：
+
+```bash
+grub-install --target=i386-pc /dev/sdx
+```
+
+生成配置文件：
+
+```bash
+grub-mkconfig -o /boot/grub/grub.cfg

+# Debtap – Convert DEB Packages Into Arch Linux Packages
+
+For this purpose, we are going to use an utility called “Debtap”. It stands DEB To Arch (Linux) Package. Debtap is available in AUR, so you can install it using the AUR helper tools such as Yay.
+
+To unstall debtap using pacaur, run:
+
+```bash
+$ yay -S debtap
+```
+
+And, make sure your Arch system should have bash, binutils, pkgfile and fakeroot packages installed.
+
+After installing Debtap and all above mentioned dependencies, run the following command to create/update pkgfile and debtap database.
+
+```bash
+$ sudo debtap -u
+```
+
+Sample output would be:
+
+```bash
+==> Synchronizing pkgfile database...
+:: Updating 6 repos...
+ download complete: archlinuxfr [ 151.7 KiB 67.5K/s 5 remaining]

+==> Generating base group packages list...
+==> All steps successfully completed!
+```
+
+You must run the above command at least once.
+
+Now, it’s time for package conversion.
+
+To convert any DEB package, say Quadrapassel, to Arch Linux package using debtap, do:
+
+```bash
+$ debtap quadrapassel_3.22.0-1.1_arm64.deb
+```
+
+The above command will convert the given .deb file into a Arch Linux package. You will be asked to enter the name of the package maintainer and license. Just enter them and hit ENTER key to start the conversion process.
+
+The package conversion will take from a few seconds to several minutes depending upon your CPU speed. Grab a cup of coffee.
+
+Sample output would be:
+
+```bash
+==> Extracting package data...
+==> Fixing possible directories structure differencies...
+==> Generating .PKGINFO file...
+
+:: Enter Packager name:
+quadrapassel
+
+:: Enter package license (you can enter multiple licenses comma separated):
+GPL
+
+*** Creation of .PKGINFO file in progress. It may take a few minutes, please wait...
+
+Warning: These dependencies (depend = fields) could not be translated into Arch Linux packages names:
+gsettings-backend
+
+==> Checking and generating .INSTALL file (if necessary)...
+
+:: If you want to edit .PKGINFO and .INSTALL files (in this order), press (1) For vi (2) For nano (3) For default editor (4) For a custom editor or any other key to continue:
+
+==> Generating .MTREE file...
+
+==> Creating final package...
+==> Package successfully created!
+==> Removing leftover files...
+```
+
+Note: Quadrapassel package is already available in the Arch Linux official repositories. I used it just for demonstration purpose.
+
+If you don’t want to answer any questions during package conversion, use -q flag to bypass all questions, except for editing metadata file(s).
+
+```bash
+$ debtap -q quadrapassel_3.22.0-1.1_arm64.deb
+```
+
+To bypass all questions (not recommended though), use -Q flag.
+
+```bash
+$ debtap -Q quadrapassel_3.22.0-1.1_arm64.deb
+```
+
+Once the conversion is done, you can install the newly converted package using “pacman” in your Arch system as shown below.
+
+```bash
+$ sudo pacman -U <package-name>
+```
+
+To display the help section, use *-h* flag:
+
+```bash
+$ debtap -h
+Syntax: debtap [options] package_filename
+
+Options:
+
+ -h --h -help --help Prints this help message
+ -u --u -update --update Update debtap database
+ -q --q -quiet --quiet Bypass all questions, except for editing metadata file(s)
+ -Q --Q -Quiet --Quiet Bypass all questions (not recommended)
+ -s --s -pseudo --pseudo Create a pseudo-64-bit package from a 32-bit .deb package
+ -w --w -wipeout --wipeout Wipeout versions from all dependencies, conflicts etc.
+ -p --p -pkgbuild --pkgbuild Additionally generate a PKGBUILD file
+ -P --P -Pkgbuild --Pkgbuild Generate a PKGBUILD file only
+```
+
+And, that’s all for now folks. Hope this utility helps. If you find our guides useful, please spend a moment to share them on your social, professional networks and support OSTechNix!
+
+More good stuffs to come. Stay tuned!
+
+Cheers!

+## 匿名映射
+
+使用映射区完成文件的读写十分方便，父子进程间通信也容易，但缺陷是每次创建映射区一定要依赖一个文件才能实现。通常为了创建映射区要 open 一个 temp 文件，创建好了再进行 unlink、close，这样比较麻烦，可以直接使用匿名映射来替代。Linux 系统提供了创建匿名映射区的方法，无需依赖文件即可创建映射区，同样需要借助标志位参数 flags 来指定。使用 `MAP_ANONYMOUS`(or `MAP_ANON`) 如：
+
+```c
+int *p = mmap(NULL, 4, PROT_READ | PROT_WRITE, MAP_SHARED | MAP_ANONYMOUS, -1, 0);
+```
+
+4 是举例表明该位置表大小，可依据实际需要填写。
+
+需要注意的是 `MAP_ANONYMOUS` 是 Linux 操作系统特有的宏，在类 Unix 系统中如果没有该宏的定义，可使用如下两步完成匿名映射区的建立：
+
+```c
+fd = open("/dev/zero", O_RDWR);
+p = mmap(NULL, 4, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);

+## Write Protect File From Command Line
+
+### Change File Flags With the chflags Command
+
+The chflags command modifies the file flags. First, open the terminal and to set system immutable flag type the following command:
+
+```bash
+sudo chflags schg fileName
+```
+
+The owner can set the user immutable flag as follows (no need to use sudo or superuser password):
+
+```bash
+chflags uchg fileName
+```
+
+In this, example set user immutable flag on resume.txt file, enter:
+
+```bash
+chflags uchg resume.txt
+```
+
+To list flags, enter:
+
+```bash
+ls -lO resume.txt
+```
+
+Sample outputs:
+
+```bash
+-rw-r--r--  1 vivek  wheel  uchg 18424 Jun  2 18:48 resume.txt
+```
+
+Now, try deleting or writing to the same file, enter:
+
+```bash
+rm resume.txt
+```
+
+Sample outputs:
+
+```bash
+override rw-r--r--  vivek/wheel uchg for resume.txt? y
+rm: resume.txt: Operation not permitted
+```
+
+### How Do I Remove User Immutable Flag?
+
+Use the command as follows:
+
+```bash
+chflags nouchg resume.txt
+ls -lO resume.txt
+```
+
+Sample outputs:
+
+```bash
+-rw-r--r--  1 vivek  wheel  - 18424 Jun  2 18:48 resume.txt
+```
+
+Putting the letters no before causes the flag to be cleared.
+
+### How Do I Remove System Immutable Flag?
+
+Use the command as follows:
+
+```bash
+sudo chflags noschg resume.txt
+ls -lO resume.txt<
+```
+
+Please note that above commands works on both the file and folder (remember, under UNIX everything is file).

+#    https://docs.rs/glutin/*/glutin/event/enum.VirtualKeyCode.html#variants
+#
+#    Instead of using the name of the keys, the `key` field also supports using
+#    the scancode of the desired key. Scancodes have to be specified as a
+#    decimal number. This command will allow you to display the hex scancodes
+#    for certain keys:
+#
+#       `showkey --scancodes`.
+#
+# Then exactly one of:
+#
+# - `chars`: Send a byte sequence to the running application
+#
+#    The `chars` field writes the specified string to the terminal. This makes
+#    it possible to pass escape sequences. To find escape codes for bindings
+#    like `PageUp` (`"\x1b[5~"`), you can run the command `showkey -a` outside
+#    of tmux. Note that applications use terminfo to map escape sequences back
+#    to keys. It is therefore required to update the terminfo when changing an
+#    escape sequence.
+#
+# - `action`: Execute a predefined action
+#
+#   - ToggleViMode
+#   - SearchForward
+#       Start searching toward the right of the search origin.
+#   - SearchBackward
+#       Start searching toward the left of the search origin.

+#       the line when already at the first cell of the row.
+#   - High
+#       Top of the screen.
+#   - Middle
+#       Center of the screen.

+#    `args` array of command line parameter strings. For example:
+#       `{ program: "alacritty", args: ["-e", "vttest"] }`
+#
+# And optionally:
+#
+# - `mods`: Key modifiers to filter binding actions
+#
+#    - Command
+#    - Control
+#    - Option
+#    - Super
+#    - Shift
+#    - Alt
+#
+#    Multiple `mods` can be combined using `|` like this:
+#       `mods: Control|Shift`.
+#    Whitespace and capitalization are relevant and must match the example.
+#
+# - `mode`: Indicate a binding for only specific terminal reported modes
+#
+#    This is mainly used to send applications the correct escape sequences
+#    when in different modes.
+#
+#    - AppCursor
+#    - AppKeypad
+#    - Search
+#    - Alt
+#    - Vi
+#
+#    A `~` operator can be used before a mode to apply the binding whenever
+#    the mode is *not* active, e.g. `~Alt`.
+#
+# Bindings are always filled by default, but will be replaced when a new
+# binding with the same triggers is defined. To unset a default binding, it can
+# be mapped to the `ReceiveChar` action. Alternatively, you can use `None` for
+# a no-op if you do not wish to receive input characters for that binding.
+#
+# If the same trigger is assigned to multiple actions, all of them are executed
+# in the order they were defined in.

+# ## About ##
+#
+# This is our team's starting point for our git commit messages.
+# You can edit this template as you like, to customize it.
+#
+# For more information about git commit ideas and help:
+# https://github.com/joelparkerhenderson/git_commit_message
+#
+#
+# ## Usage ##
+#
+# Put the template file here:
+#
+#     ~/.git_commit_template.txt
+#
+# Configure git to use the template file by running:
+#
+#     git config --global commit.template ~/.git_commit_template.txt
+#
+# Or add the template file to the ~/.gitconfig file:
+#
+#     [commit]
+#         template = ~/.git_commit_template.txt
+#
+# If you prefer other file locations or ways of working,
+# you can freely adjust the usage as you like.
