This is a tutorial on how to programmatically rotate the orientation of a view controller in iOS, specifically from landscape to portrait and vice versa, using techniques applicable to both tab bar apps and non-tab bar apps. Here’s a summary of the key points: To switch between landscape and portrait orientations programmatically, you’ll need to set the isPortrait or isLandscape property on your app delegate. This can be achieved using code like this: [(AppDelegate*)[[UIApplication sharedApplication] delegate] setIsLandscapePreferred:NO];

Group, Index, and Compute Size of Consecutive Duplicates In this article, we’ll explore how to group consecutive duplicates in a dataset, compute the index of each group, and calculate the size of each group. We’ll also discuss the importance of understanding groupby operations and how they can be applied to various data manipulation tasks.

Understanding LEFT OUTER JOINs and Filtering Results ===================================================== As a developer, you’ve likely encountered the concept of a LEFT OUTER JOIN in your SQL queries. This type of join returns all records from one table (the left table) and matching records from another table (the right table). However, sometimes you want to filter the results based on conditions that only apply when a match is found. In this post, we’ll explore how to achieve this using LEFT OUTER JOINs.
