This is a short tutorial on using symbolic links to sync files that live outside of your Dropbox or other sync folder. 

I use this to synchronize my Omnigraffle stencils and Adobe templates across multiple Macs.  Although untested, this may also be used to get around the restriction that Live Mesh imposes on not allowing items within system folders to be synced (e.g. Library on Mac or Application Support on Windows).

What is a Symbolic Link?
They are basically the UNIX equivalent to an “Alias” to a file on a Mac or a “Shortcut” in Windows.

Why do I care?
Because they are actually more powerful and can be used to do some nifty tricks.  Symbolic links can point directly to the actual file from multiple locations.  An alias or shortcut is a file in itself, and in some ways is treated like any other file.  If you were to synchronize an alias, the shortcut reference file is copied over, not the file it points to.  So we can use symbolic links to synchronize preferences or system files that live outside of your Dropbox, Live Mesh, or specific backup folder.

The readme file explains how to install, as there are a couple ways to do it depending on which Mac OS you are using.

As of this date of this posting, here is the full list of the iPhone 3GS Voice Control commands available.  Hopefully as this is adopted, they will roll out more – like finding a contact’s info or initiating an email by speaking the name.

Start Voice Control:
Press and hold the Home button or your headset middle button until the Voice Control screen appears and you hear a beep. 

Cancel Voice Control:
Tap the cancel button on the screen or say “cancel” to close Voice Control.

Call someone in your contacts:
   * call + [name of the person or phone number]
   * dial + [name of the person or phone number]

 If the person has more than one phone number, add:
   * home
   * mobile
   * work
   * other

Make a correction:
   * no
   * nope
   * not that
   * not that one
   * wrong

Music playback:
   * play
   * play music
   * play + album + [name]
   * play + artist + [name]
   * play + playlist + [name] 
   * pause
   * pause music
   * next song
   * previous song
   * shuffle

Music Info:
   * what’s playing
   * what song is this
   * who is this song by
   * who sings this song

Use Genius to play similar songs:
   * Genius
   * play more like this
   * play more songs like this

For best results:
Speak clearly, naturally (like you are making a phone call), pausing slightly so each word is distinct.  Use only iPhone commands and full names or numbers.

The steps:

1. Mount your network drive (check step-5 if you are getting error in mounting).

2. Change the preferences by running following command in a terminal window:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

3. Now turn on Time Machine.

4. Select your network drive.

5. If you lose your network mount, you will need to reset your preferences by running the following:
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 0

* AT&T: Log in at mymessages.wireless.att.com. Under Preferences, you’ll see the text-blocking and alias options. Here’s also where you can block messages from specific e-mail addresses or Web sites.

* Verizon Wireless: Log in at vtext.com. Under Text Messaging, click Preferences. Click Text Blocking. You’re offered choices to block text messages from e-mail or from the Web. Here again, you can block specific addresses or Web sites. (Here’s where you set up your aliases, too.)

* Sprint: No auto-blocking is available at all, but you can block specific phone numbers and addresses. To get started, log in at www.sprint.com. On the top navigation bar, click My Online Tools. Under Communication Tools, click Text Messaging. On the Compose a Text Message page, under Text Messaging Options, click Settings & Preferences. In the text box, you can enter a phone number, email address or domain (such as Comcast.net) that you want to block.

* T-Mobile: T-Mobile doesn’t yet offer a “block text messages from the Internet” option. You can block all messages sent by e-mail, though, or permit only messages sent to your phone’s e-mail address or alias, or create filters that block text messages containing certain phrases. It’s all waiting when you log into www.t-mobile.com and click Communication Tools.

With this method, you can create your own custom file which will override the default Mac Apache 2 server settings without modifying the original httpd.conf file.

Why not just change the httpd.conf file itself?

Well, Apache updates may overwrite this file with a new default if you reinstall and I find consolidating custom changes in one small file is easier to edit and troubleshoot. You may need admin editing permissions to do this.

How to:

1. Be sure web sharing is turned on from the “sharing” control panel in your System Preferences:

2. PHP is not enabled by default, so you need to switch this on. Open your user-specific .conf file located in the “users” directory:
/private/etc/apache2/users/.conf

The main apache config file (httpd.conf) loads its settings then will load any additional config files within the “users” directory.

3. Paste the following code into your config file:
#LoadModule php5_module libexec/apache2/libphp5.so

This can also be copied and pasted from the original config file: /private/etc/apache2/httpd.conf
or merely de-commented (remove the #) from right there if you want to set that up for all users in one go.

4. That’s it! Save your file, restart web sharing, and you should be good to go.
