Most of the projects that we work on involve either development or testing on MAC. It is, therefore, essential to know the keyboard shortcuts for MAC. Often the novices find it extremely difficult to garner the required information (in the case of PC Keyboard for MAC), so to make things easy the commonly used MAC commands are compiled and listed in this section. Before moving on to the shortcuts, the user should be familiar with the keyboard equivalents. The PC equivalent of the MAC keys are as follows :
Running multiple iOS Simulator instances is very helpful for testing purposes. This is helpful in testing same application on different devices simultaneously or with different user credentials simultaneously. The default behaviour does not allow to run more than one simulator instance from XCode. But it is possible to do it from the command line. For this change the directory into Developer/Applications in XCode.app package and run simulator with the "open" command.
To implement push notification for a project, we first created a new custom plugin to push messages into a custom table. When the cron runs, the messages stored in the queue table will be processed and saved to the custom table. For this, create a new directory "push" in message_notify/plugins/notifier/ and use it just like email or sms. The directory may contain 2 files: push.inc MessageNotifierPush.class.php In push.inc, create a plugin with class and view modes

Eighty percent of the internet website audience already watch some form of video, but mainly in short form; the average length of an Internet video stream today is only about three minutes. This is changing rapidly and the long-form video, streamed, real-time, or batched, will soon become the dominant form of content. Delivering long-form video content is bandwidth-intensive. While most low-end websites have resorted to posting video content on YouTube, this might not be a good option for those media who wish to monetize the content exclusively on their website.
