作業系統: Windows10

更改主機名稱後，會發現rabbitmq無法啟動，這時候要重新安裝Service。
注意:需要備份的資料先備份起來

1. 利用rabbitmq提供的bat(RabbitMQ Service - remove.bat)，並且以系統管理員執行
2. 利用rabbitmq提供的bat(RabbitMQ Service - (re)install.bat)，並且以系統管理員執行重新安裝service
3. 利用rabbitmq提供的bat(RabbitMQ Service - start.bat)，並且以系統管理員執行重新安裝service啟動服務
4. 成功後會看到log資料夾出現新的log，rabbit@(新的主機名稱).log，代表成功了。

vim版本:8.2

安裝套件管理員Vundle

1. 下載Vundle plugin manager並且放到VIM套件資料夾

   1	git clone https://github.com/gmarik/Vundle.vim.git ~/.vim/bundle/Vundle.vim

2. 建立套件管理檔

   1	touch ~/.vimrc

3. 將下面指令複製到~/.vimrc檔案裡面

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

   set nocompatible " required filetype off " required " set the runtime path to include Vundle and initialize set rtp+=~/.vim/bundle/Vundle.vim call vundle#begin() " alternatively, pass a path where Vundle should install plugins "call vundle#begin('~/some/path/here') " let Vundle manage Vundle, required Plugin 'gmarik/Vundle.vim' " add all your plugins here (note older versions of Vundle " used Bundle instead of Plugin) " ... " All of your Plugins must be added before the following line call vundle#end() " required filetype plugin indent on " required

4. 安裝套件

   1. 先開啟vim
   2. 輸入:
   3. PluginInstall

操作

• 分割畫面

  1. .vimrc 加入下面幾行

     1 2 3 4 5

     "split navigations nnoremap <C-J> <C-W><C-J> nnoremap <C-K> <C-W><C-K> nnoremap <C-L> <C-W><C-L> nnoremap <C-H> <C-W><C-H>

  2. ctrl加上vim的方向鍵(J下, K上, L右, H左)就可以移動到不同地方的split

• Buffers

  • :ls可以看到buffer清單
  • 可以在輸入:ls後直接:b ，就可以不用記下buffer number

• 程式碼收折

  • 在.vimrc加入下面幾行

    1 2 3 4 5 6

    " Enable folding set foldmethod=indent set foldlevel=99 " Enable folding with the spacebar nnoremap <space> za

  • 之後就可用空白鍵收折程式碼

  • 如果想要看到收折的程式碼的docstrings 可以在.vimrc加入這行

    1	let g:SimpylFold_docstring_preview=1

Visual Studio 2019
CMake 3.24

設定Opencv

• 編譯OpenCV

• 設定windows的環境變數 OpenCV_ROOT 到OpenCVConfig.cmake所在的資料夾(CMake 3.12之後的功能，文件

• 從編譯好的OpenCVConfig.cmake我們可以看OpenCV提供了那些CMake變數給我們使用，可以參考這裡

• 讓CMake複製dll文件

• 設定CMake尋找Python.h

CMake尋找Python

OpenCV

從(cmake 3.12)[https://cmake.org/cmake/help/v3.12/policy/CMP0074.html]之後，可以利用環境變數來告訴cmake套件的位置，在Windows下很方便，因為windows不像linux會把函式庫集中放在一起。設定方法就是利用設定環境變數

1

<PackageName>_ROOT

其中<PackageName>就是你的套件名稱，例如在這裡我們要設的環境變數就是OpenCV_ROOT，注意<PackageName>必須要和你寫在CMakeLists.txt裡面find_package(<PackageName>)大小寫都要一致

設定完後會看到cmake輸出找到的路徑

1
2
3

Environment variable OpenCV_ROOT is set to:

    D:\lib\build_opencv

另外由於相容性的關係，cmake預設不會使用環境變數的OpenCV_ROOT，我們必須在CMakeLists.txt中設定打開這個功能

1

cmake_policy(SET CMP0074 NEW)

成功設定後可以看到cmake會有以下輸出

1
2
3

-- Found OpenCV: D:/lib/build_opencv (found version "4.6.0")
-- OpenCV library status:
--     version: 4.6.0

詳細寫法可以參考這個範例

Eigen3.4.0

使用find_package(Eigen3 REQUIRED)後需要get_target_property(EIGEN3_INCLUDE_DIR Eigen3::Eigen INTERFACE_INCLUDE_DIRECTORIES)
，根據這個issue的寫法https://gitlab.com/libeigen/eigen/-/issues/2486

1. ssh-copy-id

• linux

• windows
  在powershell中沒有ssh-copy-id這個指令，不過我們可以用下面指令達成相同目標

  1	type $env:USERPROFILE\.ssh\id_rsa.pub | ssh {IP-ADDRESS-OR-FQDN} "cat >> .ssh/authorized_keys"

參考:
https://www.chrisjhart.com/Windows-10-ssh-copy-id/

1. 切割壓縮檔
   -v50m 表示每50MB切一包

   1	7za.exe" a -v50m "Release4.zip" "*.xlsm"

參考:

https://info.nrao.edu/computing/guide/file-access-and-archiving/7zip/7z-7za-command-line-guide#section-14

https://documentation.help/7-Zip/syntax.htm

如果在powershell 發現找不到7z 指令，可以用下面的script替代

}

Set-Alias 7zip $7zipPath

$Source = "c:\BackupFrom\backMeUp.txt"
$Target = "c:\BackupFolder\backup.zip"

7zip a -v50m -mx=9 $Target $Source #-v50m 代表將檔案分割成每50MB一包
