How to Use svnsync Command to Backup SVN Repository ?

 

Platform : Ubuntu 14.04 LTS 64bits

 

1. Create a Null SVN Repository

# sudo svnadmin create Project_Name

 

2. Modify the content of pre-revprop-change file

# cd Project_Name/hooks/

# sudo cp  pre-revprop-change.tmpl pre-revprop-change

# sudo chmod +x pre-revprop-change

# sudo vim pre-revprop-change

=> The Last Line : exit 1

=> The Last Line : exit 0

 

3. Synchornize your SVN Repostiory from my google code project

# sudo svnsync init file:///home/svn/Project_Name https://bohan-debug-utility.googlecode.com/svn/ --username spyker729@gmail.com --allow-non-empty

 

# sudo svnsync sync file:///home/svn/Project_Name https://bohan-debug-utility.googlecode.com/svn --username spyker729@gmail.com

Change the Audio Output on Raspberry Pi

1. Install related package

# sudo apt-get install alsa-utils

 

2. Modify the audio path on Raspberry Pi

# sudo amixer cset numid=3 X

 

Where X is as following:

0 = Auto

1 = 3.5 mm Audio Jack

2 = HDMI

 

numid=1,iface=MIXER,name='Master Playback Volume'

numid=2,iface=MIXER,name='Master Playback ZC Switch'

numid=3,iface=MIXER,name='Capture Volume'

numid=4,iface=MIXER,name='Capture Switch'numid=5,iface=MIXER,name='Mic Boost (+20dB)'numid=6,iface=MIXER,name='Mic Boost2 (+20dB)'numid=7,iface=MIXER,name='Mic Switch'

如何製作虛擬Floppy.img的GRUB開機介面

平台 : Ubuntu(Virtualbox)  Windows7

工具 : Bochs

 

1.開啟終端機，創立一個資料夾，並進入該資料夾

 

2.製作Floppy.img (兩者皆可)

# dd if=/dev/zero of=Floppy.img bs=1024 count=1440

# dd if=/dev/zero of=Floppy.img bs=512 count=2880

 

3.格式化Floppy.img

# mkdosfs Floppy.img

 

4.建立一個讓Floppy.img可以掛在的目錄 floppy

# mkdir floppy

 

5.掛載Floppy.img

# mount –o loop Floppy.img floppy

 

6.來這裡抓GRUB原始檔

 

7. 解壓縮(用0.96)

# tar zxvf grub-0.96-i386-pc.tar.gz

 

8.複製GRUB目錄

# sudo cp –r grub-0.96-i386-pc/* floppy

 

9.卸載floppy

# sudo umount floppy

 

10.安裝Grub

# sudo apt-get install grub

 

11.進入GRUB修改

# grub

 

12.輸入下列資訊

grub> device (fd0) floppy.img

grub> root (fd0)

grub> setup (fd0)

Checking if "/boot/grub/stage1" exists... yes

Checking if "/boot/grub/stage2" exists... yes

Checking if "/boot/grub/fat_stage1_5" exists... yes

Running "embed /boot/grub/fat_stage1_5 (fd0)"... failed (this is not fatal)

Running "embed /boot/grub/fat_stage1_5 (fd0)"... failed (this is not fatal)

Running "install /boot/grub/stage1 (fd0) /boot/grub/stage2 p /boot/grub/menu.lst "... succeeded

Done.

grub> quit

 

13.把檔案複製回Window7介面，開啟Bochs載入floppy.img 如圖設定

14.執行畫面

到此就告一段落

 

(1) 如果已經開發好作業系統者，做完第8個步驟後，加入menu.lst與kernel.elf於指定位址

 

kernel.elf (boot/kernel.elf)

menu.lst ( boot/grub/menu.lst )

title    DclabOS

root    (fd0)

kernel    /boot/kernel.elf

boot

 

(2)然後接著做步驟9之後的動作即可

 

PS : 作業系統只輸出 Test Output to monitor. …

 

搞定收工 !
