“The application-identifier entitlement is not formatted correctly; it should contain your 10-character App ID Seed, followed by a dot, followed by your bundle identifier.”

From what I can tell, the way to fix this to create a NEW entitlements file (see my previous post on creating adhoc builds for instructions on how to do this).  Previously we’d only had to create an entitlements file and uncheck “get-task-allow”.

However now it appears you also need to add a new “keychain-access-group” and add an item which includes your App Identifier (get this from the iTunes Provisioning Portal) and your bundle identifier (com.mycompany.bundle_name).

See an example below:

Hold down the “option” key and then go to the “Virtual Machine” menu option. You’ll notice that the options switch from “Shutdown” to “Force Shutdown” when you hold down the “option” key.  Simply choose your required “Force” option and you should be back in business!

How do you do this?  I’d recommend taking the following steps:

1. Get this great OAuth Twitter PHP library from Abraham Williams
2. Sign up for a Twitter application and get an application setup.  You’ll need the “Consumer Key” and “Consumer Secret” values from Twitter. You will also need to set a “callback url” that Twitter will send the user back to.  Make sure you set this correctly.
3. Include the “twitterOAuth.php” library provided by Adbraham Williams in your code

Now, the process through which OAuth works with Twitter (and any other platform) is as follows:

Firstly, you need to get the user to authenticate with twitter and permit your application to perform actions on their behalf.  To do this, you need to send the user to twitter with a special “authorisation token”.

You request an authorisation token from Twitter, using your Consumer Key and Consumer Secret values you obtained when you signed up for a Twitter Application:

$connection = new TwitterOAuth($consumer_key, $consumer_secret);
$request_token = $connection->getRequestToken();

The $request_token returned contains the “request token” information, which you should store somewhere:

$userData['Twitter_Request_Token'] = $token = $request_token['oauth_token'];
$userData['Twitter_Request_Token_Secret'] = $request_token['oauth_token_secret'];
$db->Save_User_Data($userData); // Replace with your own saving method

Now that you have your request token, you can send the user off to Twitter to authenticate:

$authenticateUrl = $connection->getAuthorizeURL($token);
header("Location: $authenticateUrl");
exit;

Twitter will now authenticate the user and confirm they want your application to have access to their account.  Your next interaction will be on the “callback url” you setup when you created your Twitter application.  In this script you will need to use the “twitter request tokens” you saved previously to then request the “Access token” from Twitter:

$to = new TwitterOAuth($consumer_key, $consumer_secret,
$userData['Twitter_Request_Token'], $userData['Twitter_Request_Token_Secret']);
$tok = $to->getAccessToken();

Now that you’ve got the access token, you should save it as you’ll use this in future requests to Twitter:

$userData['Twitter_Access_Token'] 	= $tok['oauth_token'];
$userData['Twitter_Access_Token_Secret'] = $tok['oauth_token_secret'];
$db->Save_User_Data($userData);

Now confirm you have access to the user on Twitter:

$to = new TwitterOAuth($consumer_key, $consumer_secret,
$userData['Twitter_Access_Token'], $userData['Twitter_Access_Token_Secret']);
$result = json_decode($to->OAuthRequest('https://twitter.com/account/verify_credentials.json', array(), 'GET'));
if ($result->id){
// Everything is fine
}

Now you have access to Twitter via OAuth!  You can now run commands like this:

$to = new TwitterOAuth($consumer_key, $consumer_secret, $access_token, $access_token_secret);
$result = json_decode($to->OAuthRequest(
      'https://twitter.com/statuses/update.json',
       array('status' => $tweet), 'POST'));

The above should give you a few pointers on how to actually get up and running using OAuth/PHP on Twitter.  I hope this post helps a few people get it all working.

1. Click the Apple Icon in the top left corner of the screen
2. Select “System Preferences” from the drop-down menu
3. Select “Accounts” then click the “Login Items” tab
4. From here you can now remove or add applications that start automatically when you log in

Backblaze is a backup-to-the-cloud service which costs $5 a month for unlimited backups. It deals with external hard drives, duplicate files, etc etc and requires zero configuration. Simply install and you’re done. Thoroughly recommended.

To do this, simply type:

dig domaintolookup.com +trace

1. Copy the cells you want to flip
2. Right-Click “Paste Special”
3. Tick the Transpose checkbox

You’re done! Best Excel trick ever!

rm -rf `find . -type d -name .svn`

Symptoms are pretty simple to diagnose – you start MAMP, and it’s control panel pops up and shows that everything is running:

But for some reason you can’t access your webserver or database:

What to do?  Restarting the servers generally doesn’t solve the problem.  However, there is a trick I’ve discovered.  Open up the control panel and click the “Preferences…” button.  Once this popups up, choose the “Ports” tab, change nothing – and click OK:

MAMP will automatically restart – and you should be up and running!

svn switch --relocate http://oldserver.com/PROJECT 

http://newserver.com/PROJECT

This will recursively modify all the .svn folders contents so they point to the correct location.
