鍵盤快速鍵

首先，認識一下選單上的鍵盤符號對應：

[[File:hotkeys.png|400px]]

終端機設定

一開始覺得很奇怪，為何用 screen 有顏色，不用就沒有顏色。
原因是預設的 TERM 不支援，需改為 xterm-256color 才行。
[[File:mac_terminal_xterm.png|600px]]
修改後，查詢 $TERM 環境變數應該會看到：
```
~$ echo $TERM
xterm-256color
```

Azure

若要使用命令列建立與管理 Azure 資源，您必須具備以下條件：

有 Azure 帳戶 (免費試用版) - 註冊 Azure - https://azure.microsoft.com/zh-tw/ 安裝 Azure CLI - https://azure.microsoft.com/zh-tw/documentation/articles/xplat-cli-install/ 登入使用您帳戶的相關 Azure 資源 - https://azure.microsoft.com/zh-tw/documentation/articles/xplat-cli-connect/

Azure CLI 安裝

Mac OS X

brew install npm
npm install azure-cli -g

雖然 homebrew 裡也有 azure-cli，但版本比較舊，建議用 npm 的版本。
```
~$ brew info azure-cli
azure-cli: stable 0.10.6 (bottled), HEAD
```

Docker

Docker Hub - https://hub.docker.com/r/microsoft/azure-cli/
azure-cli 的 github - https://github.com/azure/azure-xplat-cli
在 Docker主機中，執行：

docker run -it microsoft/azure-cli

小技巧

在 Docker 主機中，有 azure.completion.sh 可以讓 Azure CLI 提供指令的建議。若有需要，請在 Mac OS 的家目錄建立 .bashrc 與 .bash_profile 檔案，並 source 路徑/azure.completion.sh
如果懶得從 docker image 裡面取得 azure.completion.sh 可至以下 gist 路徑取得：

https://gist.githubusercontent.com/jazzwang/4397a4a13507fef8d94010a49337d120/raw/b7dc8b8086198d01c92f52cb5bd363d3811e0b40/azure.completion.sh

以下是我的設定，供參考：

.bash_profile

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
	. "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

.bashrc

## for Intellij IDEA
export JAVA_HOME="$(/usr/libexec/java_home)"
## for terminal 
export CLICOLOR=1
export LSCOLORS="Gxfxcxdxbxegedabagacad"
alias ls='ls -GFh'
source /usr/local/etc/bash_completion.d/git-completion.bash
source /usr/local/etc/bash_completion.d/azure.completion.sh
source /usr/local/etc/bash_completion.d/docker
source /usr/local/etc/bash_completion.d/brew
source /usr/local/etc/bash_completion.d/brew-cask
source /usr/local/etc/bash_completion.d/gradle

Azure 術語與觀念

Azure 建立和處理資源的部署模型有二種：資源管理員和傳統
傳統的文件入口：https://azure.microsoft.com/zh-tw/documentation/articles/virtual-machines-command-line-tools/
Microsoft 建議大部分的新部署使用 Resource Manager model。（常看到的 ARM 縮寫，指的就是 Azure Resource Manager）
資源管理員文件入口：https://azure.microsoft.com/zh-tw/documentation/articles/xplat-cli-azure-resource-manager/

{| class="wikitable sortable"

! 縮寫 !! 全文 !! 說明

| ASM | ARM |


Azure Resource Manager	Azure 資源管理員
Resource Group

Azure CLI 操作與管理

安裝好 Azure CLI 之後，您就能從命令列使用者介面 (Bash、終端機及命令提示字元等) 中執行 azure 命令。例如，若要執行 [說明] 命令，請輸入下列命令：

azure help

若要查看您所安裝的 Azure CLI 版本，請輸入下列命令：

azure --version

參考 https://azure.microsoft.com/zh-tw/documentation/articles/xplat-cli-connect/ 完成帳號綁定
因為使用的是 0.9.10 以後的版本，所以直接使用 azure login

azure login

~# azure --version
0.9.19 (node: 4.2.4)
root@azure:~# azure login
info:    Executing command login
-info:    To sign in, use a web browser to open the page https://aka.ms/devicelogin. Enter the code G*K*N*D*L to authenticate.
/info:    Added subscription Free Trial
info:    Setting subscription "Free Trial" as default
+
info:    login command OK

azure account

檢查 account 狀態

~# azure account list
info:    Executing command account list
data:    Name        Id                                    Current  State  
data:    ----------  ------------------------------------  -------  -------
data:    Free Trial  ####################################  true     Enabled
info:    account list command OK

azure config

由於預設是 ASM 模式，可以透過 azure config mode arm 改成 ARM 模式。
```
azure config mode arm
```

azure location

查詢目前 Azure 的機房位置

=== 建立自己的 Cask ===

* 參考文件：https://github.com/caskroom/homebrew-cask/blob/master/doc/development/adding_a_cask.md
* STEP 1: 
{{{
~$ brew cask create microsoft-azure-storage-explorer
}}}
* STEP 2: 照著修改內容 - 可以先看一下[https://github.com/caskroom/homebrew-cask/pulls 別人的 Pull Request 常被檢討什麼]
{{{
cask 'microsoft-azure-storage-explorer' do
  version :latest
  sha256 :no_check

  url 'https://go.microsoft.com/fwlink/?LinkId=708342'
  name 'Microsoft Azure Storage Explorer'
  homepage 'http://storageexplorer.com/'
  license :gratis

  app 'Microsoft Azure Storage Explorer.app'
end
}}}
* STEP 3: 檢驗是否可以正常下載
{{{
~$ brew cask audit --download microsoft-azure-storage-explorer
}}}
* STEP 4: 檢驗語法是否正確
{{{
~$ cd "$(brew --repository)"/Library/Taps/caskroom/homebrew-cask
homebrew-cask$ brew cask style --fix Casks/microsoft-azure-storage-explorer.rb
}}}
* STEP 5: 檢查安裝與反安裝是否正確
{{{
homebrew-cask$ brew cask install microsoft-azure-storage-explorer
homebrew-cask$ brew cask uninstall microsoft-azure-storage-explorer
}}}
* STEP 6: 建立新的 branch 分支
{{{
homebrew-cask$ git checkout -b microsoft-azure-storage-explorer
}}}
* STEP 7: 加入新的 Cask Formulae
{{{
homebrew-cask$ git add Casks/microsoft-azure-storage-explorer.rb
homebrew-cask$ git diff --cached
homebrew-cask$ git commit -v
}}}
* STEP 8: 送上自己的 gitlab 用來提交 Pull Request ( PS. 必須先 fork homebrew-cask 到自己的 github 帳號下 )
{{{
homebrew-cask$ git push https://github.com/jazzwang/homebrew-cask microsoft-azure-storage-explorer
}}}
* STEP 9: 等 homebrew-cask 的 Travis CI 通過，若有錯誤，就還要反覆修改並重新提交內容。

=== 更新自己的 Cask ===

* 參考: https://github.com/caskroom/homebrew-cask/blob/master/CONTRIBUTING.md#updating-a-cask
* STEP 1: 安裝 `cask-repair`
{{{
# install and setup script - only needed once
brew install vitorgalvao/tiny-scripts/cask-repair
cask-repair --help

# fork homebrew-cask to your account - only needed once
cd "$(brew --repository)/Library/Taps/caskroom/homebrew-cask/Casks"
hub fork
cask-repair --pull origin --push jazzwang microsoft-azure-storage-explorer
}}}
或
{{{
cask-repair microsoft-azure-storage-explorer
}}}
* STEP 2: 照著問題回答，例如修改版號、修改下載網址等
{{{
Type the new version (or leave blank to use the current one)
> 0.8.0
Paste the new URL (or leave blank to use the current one)
> http://go.microsoft.com/fwlink/?LinkId=708342
}}}

=== Homebrew Tap ===

* 舉凡官方不收或是有 license 疑慮的 formula 變可透過 Homebrew Tap 的方式來自已管理。
* [參考] https://blog.gasol.tw/make-your-own-homebrew/

== Tableau ==

* 為了看 DSP 與 DMP 的 Daily Report，可以使用 Tableau 來觀察 CSV 檔的內容。
* Mac 安裝
{{{
brew install Caskroom/cask/tableau-public
}}}

== Hadoop ==

* 在 Mac 上安裝單機版(local mode)的 Hadoop 還蠻簡單的，只需要透過 `brew` 就可以裝好。
* Mac 安裝
{{{
brew install hadoop
}}}

== Hive ==

* 在 Mac 上安裝單機版(local mode)的 Hive 還蠻簡單的，只需要透過 `brew` 就可以裝好。
* Mac 安裝
{{{
brew install hive
}}}

== Spark ==

* 在 Mac 上安裝單機版(local mode)的 Apache Spark 還蠻簡單的，只需要透過 `brew` 就可以裝好。
* Mac 安裝
{{{
brew install apache-spark
}}}

== Gist ==

* http://defunkt.io/gist/
* https://github.com/defunkt/gist
* RubyGems 安裝:
{{{
gem install gist
}}}
* Mac 安裝
{{{
brew install gist
}}}
* Debian / Ubuntu 安裝
{{{
apt-get -y install gist
}}}
* 使用
** 登入 - `gist --login`
** 上傳單一檔案 - `gist file1`
** 上傳多個檔案 - `gist file1 file2`
** 上傳 STDIN 到指定檔名 - `指令 | gist -f "檔名"`
** 複製 gist URL 到剪貼簿 - `指令 | gist -c`

== Bash ==

* 偶爾會用到一些 Bash 的色塊 COLOR
* 參考文件：
** http://www.tldp.org/HOWTO/Bash-Prompt-HOWTO/x329.html
** https://wiki.archlinux.org/index.php/Bash/Prompt_customization
* TLDP 的測試腳本可以在 gist 取得
** https://gist.github.com/jazzwang/55203a9f33386e0e567328fb86ebf7db

== Spring Boot ==

* 假設 project 名稱是 tenmax-audience-library ，主程式的 package 是 io.tenmax
* 要切換 Spring Profile 可以在環境變數中，設定 `SPRING_PROFILES_ACTIVE` 為特定的 profile 名稱
** [參考] http://stackoverflow.com/questions/23367507/how-to-pass-system-property-to-gradle-task
{{{
export SPRING_PROFILES_ACTIVE=dev
}}}
* 若要切換 log4j 的 level 一般要在 `application.yml` 先改好
** [參考] http://stackoverflow.com/questions/20485059/spring-boot-how-can-i-set-the-logging-level-with-application-properties
** 因為有使用 gradle 的 `application` plugin，參考產生出來的 `bin/tenmax-audience-library` start script，發現可以在環境變數中，設定 `TENMAX_AUDIENCE_LIBRARY_OPTS`
{{{
export TENMAX_AUDIENCE_LIBRARY_OPTS="-Dlogging.level.io.tenmax=DEBUG"
}}}

== Intellij IDEA CE ==

* MAC OS X 安裝
