Leap Year

为什么要设置闰年

四年一闰
百年不闰
四百年又闰

$$ 回归年 = 365 天 5 小时 48 分 46 秒 \approx 365.2422(天) $$

如果不加以调整，那么经过800年，差距为194天，夏天可以过新年：

$$ 0.2422 \times 800 \ \approx 194(天) $$

如何吸收误差

把这些差距转化为以天为单位：

$$ 5 小时 48 分 46 秒 = a = \frac{10463}{43200} = \frac{1}{4 + \frac{1}{7 + \frac{1}{1 + \frac{1}{3 + \frac{1}{5 + \frac{1}{64}}}}}} \approx 0.242199074(天) $$

由a1可知每4年加一天比较好一些, 故四年一闰。

$$ a_1 = \frac{1}{4} = 0.25(天) $$

由a2可知每49年加7天比较好一些。

$$ a_2 = \frac{1}{4 + \frac{1}{7}}= \frac{7}{49} \approx 0.2413793(天) $$

由a3可知每33年加8天比较好一些，那么99年就是24天，故百年不闰。

$$ a_3 = \frac{1}{4 + \frac{1}{7 + \frac{1}{1}}} = \frac{8}{33} \approx 0.2424242(天) $$

由a的真实值可知，每43200年应该加10463天，但是按照100年加24天的逻辑来算，43200年才加了10368天。

$$ \frac{24}{100} \times 43200 = 10368(天) $$

与真实值间差距为95天。

$$ 10463 - 10368 = 95(天) $$

因为大约40000年少加100天，所以，大约每400年又加1天，故四百年又闰。

按照现在及的计算逻辑，在这43200年中，一共加的天数是：

$$ 10368 + \frac{1}{400} \times 43200 = 10476(天) $$

比实际多加了

$$ 10476 - 10463 = 13(天) $$

解决办法是每3323年减去一个闰年。

$$ \frac{43200}{13} \approx 3323.0769(年) $$

Linux 2FA Authentication

Prepare

1. Install Google Authenticator or Microsoft Authenticator in your telephone.

2. Install libpam-google-authenticator in your Linux.

For Debian/Ubuntu:

sudo apt-get install libpam-google-authenticator -y

For CentOS/RHEL:

sudo yum install epel-release -y
sudo yum install libpam-google-authenticator -y

Configure

1. Run google-authenticator in your Linux.

google-authenticator

2. Configure the settings.

• Do you want authentication tokens to be time-based (y/n) y

• Then scan the QR code into your phone:

• Enter code from app (-1 to skip): -1

• Do you want me to update your "/home/auther/.google_authenticator" file? (y/n) y

In this file you will find the secret key for your authenticator. When your tokens are lost, you can use these token to login in emergency.

• Do you want to disallow multiple uses of the same authentication token? This restricts you to one login about every 30s, but it increases your chances to notice or even prevent man-in-the-middle attacks (y/n) y

您是否要禁止多次使用同一个身份验证令牌？这会限制您每 30 秒登录一次，但这会增加您注意到甚至阻止中间人攻击的机会 (y/n)

• By default, a new token is generated every 30 seconds by the mobile app. In order to compensate for possible time-skew between the client and the server, we allow an extra token before and after the current time. This allows for a time skew of up to 30 seconds between authentication server and client. If you experience problems with poor time synchronization, you can increase the window from its default size of 3 permitted codes (one previous code, the current code, the next code) to 17 permitted codes (the 8 previous codes, the current code, and the 8 next codes). This will permit for a time skew of up to 4 minutes between client and server. Do you want to do so? (y/n) n

默认情况下，移动应用程序每 30 秒生成一个新令牌。 为了补偿客户端和服务器之间可能出现的时间偏差， 我们允许在当前时间之前和之后生成一个额外的令牌。这允许身份验证服务器和客户端之间的时间偏差最多为 30 秒。如果您遇到时间同步不佳的问题，您可以将窗口从默认的 3 个允许代码（一个前一个代码、当前代码、下一个代码）增加到 17 个允许代码（8 个前一个代码、当前代码和 8 个下一个代码）。这将允许客户端和服务器之间的时间偏差最多为 4 分钟。 你想这样做吗？（是/否）

• If the computer that you are logging into isn't hardened against brute-force login attempts, you can enable rate-limiting for the authentication module. By default, this limits attackers to no more than 3 login attempts every 30s. Do you want to enable rate-limiting? (y/n) y

如果您登录的计算机没有针对暴力登录尝试进行强化，您可以为身份验证模块启用速率限制。 默认情况下，这会将攻击者的登录尝试次数限制为每 30 秒不超过 3 次。 是否要启用速率限制？（是/否）

Modify the configuration file

1. Edit the configuration file of PAM, enable 2FA.

sudo vim /etc/pam.d/sshd

Add the following lines to the top of the file.

auth required pam_google_authenticator.so

2. Edit the configuration file of SSH, enable 2FA.

sudo vim /etc/ssh/sshd_config

• ChallengeResponseAuthentication

ChallengeResponseAuthentication yes

ChallengeResponseAuthentication 是 SSH 服务端（sshd_config）的一个配置选项，用于控制是否启用 质询-响应认证（Challenge-Response Authentication） 机制。 它允许服务器向客户端发送一个或多个“质询”（例如文本提示、验证码请求等），客户端需正确响应才能完成认证。

• UsePAM

UsePAM yes

若 ChallengeResponseAuthentication yes，必须同时启用 UsePAM yes，否则质询无法通过 PAM 模块传递。

• KbdInteractiveAuthentication

KbdInteractiveAuthentication yes

KbdInteractiveAuthentication：控制是否启用键盘交互认证（UI 交互层）。

• AuthenticationMethods

AuthenticationMethods publickey password keyboard-interactive

使用公钥、密码和验证码的方式进行登陆

3. Config overview

FZF

Official Website

• Github repo

• HandBook

Install

# Clone the fzf repository
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf

# Run the install script
~/.fzf/install

Setting .bashrc

A basic example, to show how to link progress with fzf.

# add a alias to change git branch
alias gcb="git branch | fzf --preview 'git show --color=always {-1}' \
                 --bind 'enter:become(git checkout {-1})' \
                 --height 60% --layout reverse"

Then, setting ENV vars of fzf, unlock advanced function.

# fzf init
eval "$(~/.fzf/bin/fzf --bash)"
[ -f ~/.fzf.bash ] && source ~/.fzf.bash

Default fzf self build-in Ctrl+R to display history cmd, Ctrl+T to show files and dirs of local path, Alt+C to exec cd cmd. Well, you can rewrite these function.

# CTRL-Y to copy the command into clipboard using pbcopy
export FZF_CTRL_R_OPTS="
  --bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
  --color header:italic
  --header 'Press CTRL-Y to copy command into clipboard'
  --height 80% --layout reverse"

# Preview file content using bat (https://github.com/sharkdp/bat)
export FZF_CTRL_T_OPTS="
  --walker-skip .git,node_modules,target
  --preview 'batcat -n --color=always {}'
  --bind 'ctrl-/:change-preview-window(down|hidden|)'
  --height 80% --layout reverse"

# Print tree structure in the preview window
export FZF_ALT_C_OPTS="
  --walker-skip .git,node_modules,target
  --preview 'tree -C {}'
  --height 80% --layout reverse"

# ripgrep->fzf->vim [QUERY]
# sudo apt install -y ripgrep
rfv() (
  RELOAD='reload:rg --column --color=always --smart-case {q} || :'
  OPENER='if [[ $FZF_SELECT_COUNT -eq 0 ]]; then
            vim {1} +{2}     # No selection. Open the current line in Vim.
          else
            vim +cw -q {+f}  # Build quickfix list for the selected items.
          fi'
  fzf --disabled --ansi --multi \
      --bind "start:$RELOAD" --bind "change:$RELOAD" \
      --bind "enter:become:$OPENER" \
      --bind "ctrl-o:execute:$OPENER" \
      --bind 'alt-a:select-all,alt-d:deselect-all,ctrl-/:toggle-preview' \
      --delimiter : \
      --preview 'batcat --style=full --color=always --highlight-line {2} {1}' \
      --preview-window '~4,+{2}+4/3,<80(up)' \
      --query "$*"
)

In fzf model, you can press Esc to quit fzf model.

CI & CD

Overview

CI/CD, which stands for continuous integration and continuous delivery/deployment, aims to streamline and accelerate the software development lifecycle.

Continuous integration (CI) refers to the practice of automatically and frequently integrating code changes into a shared source code repository. Continuous delivery and/or deployment (CD) is a 2 part process that refers to the integration, testing, and delivery of code changes. Continuous delivery stops short of automatic production deployment, while continuous deployment automatically releases the updates into the production environment.

Why is CI/CD important?

CI/CD helps organizations avoid bugs and code failures while maintaining a continuous cycle of software development and updates.

As apps grow larger, features of CI/CD can help decrease complexity, increase efficiency, and streamline workflows.

Because CI/CD automates the manual human intervention traditionally needed to get new code from a commit into production, downtime is minimized and code releases happen faster. And with the ability to more quickly integrate updates and changes to code, user feedback can be incorporated more frequently and effectively, meaning positive outcomes for end users and more satisfied customers overall.

Jenkins CI

Jenkins Variables

Jenkins 提供了许多内置变量，可以用来生成唯一的镜像标签。常用的变量包括：

• BUILD_ID：当前构建的唯一 ID。

• BUILD_NUMBER：当前构建的编号（每次构建递增）。

  

• GIT_COMMIT：当前 Git 提交的 SHA-1 哈希值（前 7 位即可）。

• BRANCH_NAME：当前 Git 分支的名称。

Generally, you can find GLIBCXX_3.4.32 in your system. Next, just copy libstdc++.so.6* to default path that in error log.

sudo cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6* /home/knight/miniconda3/lib/

Vim Support System Clipboard

Check Vim version

vim --version | grep clipboard

Output:

knight@Lenovo:~$ vim --version | grep "clipboard"
-clipboard         +keymap            +printer           +vertsplit
+ex_extra          +mouse_netterm     +syntax            -xterm_clipboard

-clipboard -xterm_clipboard means that vim not support system clipboard.

Remove vim

Uninstall vim if you have installed.

sudo apt remove vim && sudo apt autoremove

Install vim-gtk3

sudo apt install vim-gtk3

Check Vim version again

vim --version | grep clipboard

Output:

knight@Lenovo:~$ vim --version | grep clipboard
+clipboard         +keymap            +printer           +vertsplit
+ex_extra          +mouse_netterm     +syntax            +xterm_clipboard

Confirem the key value is +clipboard or +xterm_clipboard.

Edit .vimrc

set clipboard=unnamedplus

The last you can use "*y to copy the text to system clipboard.

Use Xclip

sudo apt install xclip

Modify .vimrc

vnoremap Y :w !xclip -i -sel c<CR>

Then you can select some contents in visual mode, and press Y. Finally, you can use <Ctrl-v> to paste it anywhere.

Useful Scripts

In Linux, you can use some scripts to do some repetitive tasks.

Push Docker Images to Private Registry

Tips：When install images, you need open the proxy, but you must close it before push.

Extract Images Name to File

From the Helm's values.yaml, extract the images name and tag to images.tmp.

Usage：get_images.sh values-nginx.yaml

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com

# * Description   : Extracts Docker image names and tags from a YAML file and writes them to images.tmp
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <values-nginx.yaml>"
  exit 1
fi

# 从命令行参数获取文件名
input_file="$1"

# 清空或创建 images.tmp 文件
> images.tmp

while read -r line; do
  if [[ $line == *"repository:"* ]]; then
    repository=$(echo $line | cut -d':' -f2 | xargs)
  elif [[ $line == *"tag:"* ]]; then
    tag=$(echo $line | cut -d':' -f2 | xargs)
    # 将结果写入 images.tmp 文件
    echo "$repository:$tag" >> images.tmp
  fi
done < "$input_file"

Pull Docker Images

Install all dcoker images in images.tmp file, one by one. If you have else docker images_list file, you can use it instead, just confirm every lines only has one docker image name.

Usage：pull_images.sh images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com

# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <images.tmp>"
  exit 1
fi

# 从命令行参数获取文件名
input_file="$1"

# 读取文件并拉取每个镜像
while read -r image; do
  if [ -n "$image" ]; then
    echo "正在拉取镜像: $image"
    docker pull "$image"
  fi
done < "$input_file"

Rename Docker Images

The modified image names will be saved in the new_images.tmp file. And you can modify the private_registry to change the registry you want to push to.

Usage：update_images.sh images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-13 16:06
# * Filename      : update_and_tag_images.sh
# * Description   : Updates image paths and tags Docker images based on a specified file
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <images.tmp>"
  exit 1
fi

# 从命令行参数获取文件名
input_file="$1"
output_file="new_images.tmp"
private_registry="192.167.3.18/"

# 创建或清空输出文件
> "$output_file"

# 处理文件内容并执行 docker tag 命令
while IFS= read -r original_image; do
  # 检查行是否为空
  if [[ -n "$original_image" ]]; then
    # 在镜像名称前加上私有仓库地址
    new_image_name="${private_registry}${original_image}"
    
    # 输出正在标记的镜像信息
    echo "正在标记镜像: docker tag $original_image $new_image_name"
    
    # 执行 docker tag 命令
    docker tag "$original_image" "$new_image_name"
    
    # 将新的镜像名称写入输出文件
    echo "$new_image_name" >> "$output_file"
  fi
done < "$input_file"

echo "所有镜像已成功标记并保存到 $output_file"

After Tag docker images, you must check the new_images_name.tmp, ensure the image names are correct. And you must confirm about projects created in your private harbor.

Push Images

Push images to a remote registry. This script reads a list of image names from a file named "new_images.tmp", and pushes them to a remote registry.

Usage：push_images.sh new_images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com

# * Description   : Push Docker images to a registry
# **********************************************************

# 检查是否传入文件名作为参数
if [ "$#" -ne 1 ]; then
  echo "用法: $0 <images.tmp>"
  exit 1
fi

# 从命令行参数获取文件名
images_file="$1"
target_registry="192.167.3.18/library/"

# 遍历images.tmp文件中的每一行
while IFS= read -r line; do
    # 检查行是否为空
    if [ -z "$line" ]; then
        continue
    fi

    # 打印操作信息
    echo "正在推送镜像: $line"

    # 推送镜像
    docker push "$line"

done < "$images_file"

echo "所有指定的镜像已被推送。"

Delete Images from Local

Delete images from local.

Usage：delete_images.sh new_images.tmp

#!/bin/bash
# **********************************************************
# * Author        : Burgess Leo
# * Email         : liuxp731@qq.com
# * Create time   : 2024-09-14 09:02
# * Filename      : delete_images.sh
# * Description   : Delete images that pushed
# **********************************************************

# 检查是否有参数传递
if [ $# -ne 1 ]; then
    echo "Usage: $0 <path-to-file>"
    exit 1
fi

# 指定包含镜像名称的文件路径
images_file="$1"

# 检查文件是否存在
if [ ! -f "$images_file" ]; then
    echo "Error: File '$images_file' not found."
    exit 1
fi

# 逐行读取文件中的镜像名称
while IFS= read -r image; do
    # 删除镜像，忽略不存在的镜像
    if docker rmi "$image" &>/dev/null; then
        echo "Image $image has been deleted."
    else
        echo "Image $image does not exist or could not be deleted."
    fi
done < "$images_file"

echo "All listed images have been processed."

All Kinds of Proxy Setting

In china, you can't access to the real Internet directly. So you have to use some proxy in some software.

Configure System Proxy

Edit a Script

sudo vim  /etc/profile.d/proxy.sh

#!/bin/bash

set_proxy() {
    # set proxy config via profile.d - should apply for all users
    export http_proxy="http://127.0.0.1:7890/"
    export https_proxy="http://127.0.0.1:7890/"
    export ftp_proxy="http://127.0.0.1:7890/"
    export no_proxy="127.0.0.1,localhost"
    # For curl
    export HTTP_PROXY="http://127.0.0.1:7890/"
    export HTTPS_PROXY="http://127.0.0.1:7890/"
    export FTP_PROXY="http://127.0.0.1:7890/"
    export NO_PROXY="127.0.0.1,localhost"
    echo "Proxy has been set."
}

unset_proxy() {
    # unset proxy config
    unset http_proxy
    unset https_proxy
    unset ftp_proxy
    unset no_proxy
    # For curl
    unset HTTP_PROXY
    unset HTTPS_PROXY
    unset FTP_PROXY
    unset NO_PROXY
    echo "Proxy has been unset."
}

case $1 in
    set)
        set_proxy
        ;;
    unset)
        unset_proxy
        ;;
    *)
        echo "Usage: source $0 {set|unset}"
        ;;
esac

Add Exec Permission

sudo chmod +x  /etc/profile.d/proxy.sh

Apply Setting

source /etc/profile.d/proxy.sh
