The Problem Apple's Safari web browser is configured to block third-party cookies by default, unless the user has had prior interactions with the third-party domain: http://webpolicy.org/2012/02/17/safari-trackers/ The Solution The idea is simple, just make sure the user visits the iframe domain (in this example, B.com) at least once. One way is to run a popup that visits B.com (and set the P3P header ), then close the popup. On the parent window: var win = window.open(' http://B.com /startsession.php', '_blank', 'height=200,width=150'); setTimeout(function() { win.close(); // close it after 1 second :) }, 1000); Then in the startsession.php , just set the header will do <?php header('P3P: CP="IDC DSP COR CURa ADMa OUR IND PHY ONL COM STA"'); session_start(); Done.

Been searching for ways to calculate rectangle area with google.maps.geometry.spherical.computeArea(), but hard to find. Here's the snippet of the code I found on stackoverflow .

The image of the zoom Control Set tools were distorted after introducing Twitter Bootstrap Was wondering why the Google Maps Control Set tools works displaying correctly on standalone page but not when the same snippet pasted in my project site. Took me a while to figure out its because of Twitter Bootstrap CSS interfering with Google Maps images. The simple workaround was posted in  Twitter Bootstrap Github Issue . <style type="text/css"> /** FIX for Bootstrap and Google Maps Info window styes problem **/ img[src*="gstatic.com/"], img[src*="googleapis.com/"] { max-width: none; } </style> Hope this helps! :)

1. Download mongo.so from  https://github.com/stennie/mongo-php-driver/downloads 2. Copy mongo.so to MAMP PHP folder. For example, mine is at /Applications/MAMP/bin/php/ php5.4.10 /lib/php/extensions/no-debug-non-zts-20100525/ Remember to select the correct PHP version. You can check your PHP version from your MAMP start page, e.g http://localhost/MAMP/phpinfo.php 3. Enable the extension in PHP Configuration file (php.ini). You can find the path to the file from the PHPInfo (see above example). To enable, add the following line in the " Dynamic Extension " section. extension=mongo.so 4. Restart your MAMP. You should see " mongo " section in PHPinfo .

Got this weird " An error occurred in the upload. Please try again later " error whenever I try to do media uploads in Wordpress. I've checked the folder permission, its correct. In fact, the files were uploaded successfully to wp-content > upload folder. I've tried all kinds of suggestion in forums (disable all plugins, enable them one by one... etc), but still no avail. In the end, I decided to do a "Re-install", and that... worked! And all the uploaded files were intact. ----- Didn't dig deep into finding out what causes the issue. But a wild guess would be something to do with the PHP codes. Because the uploaded files were stored in DB, although the upload status indicated "failed". Most likely something to do with the permission issue highlighted in this blog post .
