How to indent in Facebook post/comment on OS X

1. Put your cursor on the text box of the post/comment you want to indent
2. Go to the menubar at the top of the screen
3. Edit > Emoji & Symbols
4. On Characters window, click setting icon. It's a gear nearly the top-left of the window, close to 3 color buttons.
5. Choose Customize Lists...
6. Choose Code Tables > Unicode and Done
7. Go to Unicode section at the end of the most left panel of Characters window
8. Look for the character number 3000. It's called "IDEOGRAPHIC SPACE"
9. Double click on that character to insert it to your text box. You can insert it as many characters as you want.

On OS X, Java Control Panel and Terminal show different Java versions

That's because Java Control Panel shows version of JRE for normal Mac user, but command line on Terminal shows version of JDK. To update JDK version, need to download the full package from Oracle website.
Older JDK version won't be replace automatically to allow us to switch back if we want. So we have to manually remove it by following the instruction here http://docs.oracle.com/javase/8/docs/technotes/guides/install/mac_jdk.html#A1096903

Get terminal to speak after finished a long processing command on OSX

Just append
 && say "Done"

For example;
 $ sleep 10 && say "Done"

This trick could be useful if you are running some tasks and want switch to work on something else while it's running but also want to get back to it immediately after it finished.

[Fixed][VIM] E354: Invalid register name: '*'

This error occurs when you or some of your vim plugins try to access register '*' which is a system clipboard. In default Mac OSX vim, it is compiled without system clipboard support enable. You can check this by run command :version inside vim. In the result, you will see -clipboard. Disable is -, enable is +.

To solve this issue, you need to compile vim with +clipboard yourself. I suggest OSX users to use brew to help this process. Out-of-the-box brew compiles vim with +clipboard. To do this run

brew install vim

Then you might need to create a new symbolic link from your vi command to point to the newly installed vim.
First you need to know the path of your new vim. Run

brew info vim

You should see something similar to /usr/local/Cellar/vim/7.3.875 in the result which means your vim binary file is at /usr/local/Cellar/vim/7.3.875/bin/vim. To create a new symbolic link for vi, first you need to remove the existing link

sudo rm /usr/bin/vi

Then you can create a new link.

sudo ln -s /usr/local/Cellar/vim/7.3.875/bin/vim /usr/bin/vi

Mac OS X Terminal shortcut keys

Terminal is one of the most frequently using application everyday but I have never had a chance to master its short keys. Today is a good day to start.

As I know, Terminal's short keys come from Emac, when I refer to meta short keys it means that you can use esc button or setting option(alt) button as a meta key. (Settings > Keyboard > Use option as meta key)

• Ctrl + a = Go to the beginning of the line
• Ctrl + e = Go to the end of the line
• Ctrl + l or Command + k = Clear screen
• Ctrl + r = Search for previous commands (pressing more r to get earlier commands)
• Ctrl + w = Delete the word before cursor
• Meta + d = Delete the word after the cursor
• Ctrl + u = Clear the line before cursor
• Ctrl + k = Clear the line after cursor
• Meta + t = Swap last 2 words before cursor
• Ctrl + d = Delete a character after cursor
• Meta + f = Move cursor to the right one word
• Meta + b = Move cursor to the left one word
