this.InitializeComponent();
SettingsPane.GetForCurrentView().CommandsRequested += OnCommandsRequested;

I'm new to the world of BDD, but I'd like to get a grip of it as soon as possible. It's one of my first tests:

if (this.constructor === Fluent) {
throw new Error("Can't initialize an abstract cl...0
In my MUD game engine, I built a messaging api that allows objects to subscribe to concrete implementations of an IMessage interface. Is there anything glaringly bad about the approach I have taken?
The intended use-case is for objects, such as an IPlayer implementation, to subscribe to WhisperM...

What is considered to be a good programming practice for returning value from the function, for example if we have a function in C named list* after( list *node) which returns the node which is after the node pointer. Here we have the first option:-
node *after(node *first_ptr, node *nod_ptr)

Advanced Format is a generic term pertaining to any disk sector format used to store data on magnetic disks in hard disk drives (HDDs) that exceeds 512 to 528 bytes per sector, such as the 4096-byte (4 KB) sectors of the first-generation Advanced Format hard disk drives. Larger sectors use the storage surface area more efficiently for large files but less efficiently for smaller files, and enable the integration of stronger error correction algorithms to maintain data integrity at higher storage densities.
Advanced Format is also considered a milestone technology in the history of HDD storage,...
