Best architectural approaches for building iOS networking applications (REST clients)

People implement complex logic to get valid, predictable caching like e.g. monoidal caching with projections base...
Why #define TRUE (1==1) in a C boolean macro instead of simply as 1?

Aside from template extension, Jade brings nothing worthwhile to the table that Angular doesn't already supply. Let's be honest: Using the sound principle of "favour compo...
Why no love for SQL? [closed]
...e.
If you're doing a very simple script or application, you can afford to mix SQL calls in your code wherever you like. However, if you're doing a complex system, isolating the database calls in separate module(s) is a good practice and so it is isolating your SQL code. It improves your code's read...
