unique_lockis an RAII (Resource Acquisition Is Initialization) wrapper for locking and unlocking the given mutex. It's conceptually identical to thelockstatement in C#. It simplifies exception handling by tying the mutex acquisition and release to the lifetime of theunique_lockinstance....
Yeah, in most high-level languages exception handeling is preffered to goto. But some lower-level languages like C don't have that construct. Note that exception handling allows to go straight from inside a function to the error-handling code outside the function, which is an advantage over...
This question has some great suggestions for handling this in a way that is engaging and fun for both the DM and the player: I gave a too powerful magic item at too low level for a bad reason, what to do? This situation is a little bit different than...
Understanding the relationship between urban form and structure and spatial inequality of property flood risk has been a longstanding challenge in urban planning and emergency management. Here we explore eight urban form and structure features to explain

Dial-peers can be configured with both inbound and outbound match statements so matching the same dial-peer for both the in-leg and out-leg is possible if a valid inbound and outbound matching configuration is applied to that specific dial-peer. Note: The exception to this r...
Abstraction is a mechanism to' hide irrelevant details and represent only the essential features so that one can focus on important things at a time; It allows managing complex systems by concentrating on the essential features only. For example, while d

This kind of handling is repetitive and buries the actual intention under a lot of boilerplate. As Haskell uses layout (i.e. indentation) instead of curly brackets to separate blocks the code will end up in what is called the dreaded staircase: it marches to the right of the screen....
In that specific sense, from the compiler’s perspective, a stack frame is just the entry and exit code for the routine, that pushes an anchor to the stack – that can also be used for debugging and for exception handling. Debugging tools may scan the stack data and use these anchors fo...
