Unison: An Elegant File Sync App

Ever since I got an 24" iMac at work, how to sync between this iMac and my MacBook has being a problem for me. First of all, the place I work has a very tight security policy and everything has to go through either VPN or an SSH gateway. I eventually figure out how to do SSH tunnel, but that's the topic for another day.

Once I set up the SSH connection between the iMac and the MacBook, it is easy to use rsync to sync files. However, I am not really into this whole command-line thing, otherwise I'd just get a linux box. Fortunately, I found this nice little app called Unison, which provides a GUI for Mac OS X. The setup is straightforward. There is only one catch: both machines should have Unison installed. I actually found this out by scanning through the console log. One small complain: there is practically no documentation, everything has to be found through google.

Below is quoted from Unison website

Unison runs on both Windows and many flavors of Unix (Solaris, Linux, OS X, etc.) systems. Moreover, Unison works across platforms, allowing you to synchronize a Windows laptop with a Unix server, for example.

Since I cannot find a screenshot of Unison running on OS X on its website, I figured it'll be helpful to upload one here:

Plain text in Mail.app by default

I generally prefer plain text when writing emails. However, in the place where I work, a lot of people use Microsoft Outlook or its web version. By default, it sends out emails in HTML. Even worse is the fact that the font size in those emails is too small. To reformat all incoming email and display them as plain text, quit Mail.app, type

# defaults write com.apple.mail PreferPlainText -bool TRUE

Relaunch Mail.app and enjoy.

To revert back, use

# defaults delete com.apple.mail PreferPlainText

Play rmvb format using MPlayer

MPlayer is my favorite media player on Mac OS X. I really don't understand the great disparity in terms of user numbers between VLC and MPlayer, as shown on osx.iusethis.com. In my experience, MPlayer plays more formats than VLC does and has better subtitle support. I don't mean to diminish VLC but I think at least these two players should be similar in every aspect.

In any case, both MPlayer and VLC are way better than the bloated RealOne player. However, sometimes I need play rmvb file but it is not supported by MPlayer out of box. In this case, first download RealOne, then copy all the bundles in

RealPlayer.app/Contents/Frameworks/HXClientKit.framework/HelixPlugins/Codecs

to

/usr/local/lib/codecs

If you don't have the second folder then create it first.

Oh, don't forget to delete RealOne afterwards.

A 'Perfect' iTunes Equalizer Setting

I recently came across this post on MacOSXHints.com. The modified equalizer sounds amazing. Simply copy the applescript below and run it in script editor

tell application "iTunes"
 tell EQ preset 1 -- the Manual setting which you can then save
  set band 1 to -8
  set band 2 to -5
  set band 3 to -3
  set band 4 to -4
  set band 5 to -5
  set band 6 to -6
  set band 7 to -4
  set band 8 to -2
  set band 9 to 0
  set band 10 to -3
  set preamp to 6
 end tell
end tell

This is how it looks.

Save the preset and enjoy!

Single window mode in Safari

Another hidden preference...

# defaults write com.apple.Safari \
  TargetedClicksCreateTabs -bool true

Right click on a mac laptop

I've been using control+click for right click for ages on my macbook and I have complained about the lack of a control key on the right side of the space bar. But now I just found out that there is an option in System Preferences under Keyboard & Mouse that allows you to right click by putting two fingers on the trackpad. See the screenshot.



This is just way better than control+click!

Collect all open windows to one space

I love using Space, especially after replacing an aging 15" PowerBook (more than 4 years old) with a brand new MacBook with a relatively small 13" screen.  However, sometimes I found my application windows are all over the four spaces I opened and I need a quick way to move them into one space.

Here is the trick: Enter space, press c, all windows will be collected into the first space.  Press shift+c to watch the slow motion.  Enjoy!

Several Mac OS X tips

1. Getting tired of the default background of login window? You can change it by

# sudo defaults write \
  /Library/Preferences/com.apple.loginwindow \
  DesktopPicture '/Path/To/Your/Picture'

2. Set default path for every application in Mac OS X:

# mkdir ~/.MacOSX
# defaults write ~/.MacOSX/environment "PATH"  $PATH

Log out then log in and you are all set. You can also use this method for other shell variables.

3. When you use spotlight to search content of PDF files, clicking on the result will bring up Preview.app, showing the highlighted text at a very large scale, effectively rendering this feature useless. To change it,

# defaults write com.apple.Preview Preview \
  -dict-add PVPDFSpotlightSelectionSize 1
