Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

	Brick –> is basic storage (directory) on a server in the trusted storage pool.
	Volume –> is a logical collection of bricks.
	Cluster –> is a group of linked computers, working together as a single computer.
	Distributed File System –> A filesystem in which the data is spread across the multiple storage nodes and allows the clients to access it over a network.
	Client –> is a machine which mounts the volume.
	Server –> is a machine where the actual file system is hosted in which the data will be stored.
	Replicate –> Making multiple copies of data to achieve high redundancy.
	Fuse –> is a loadable kernel module that lets non-privileged users create their own file systems without editing kernel code.
	glusterd –> is a daemon that runs on all servers in the trusted storage pool.
	RAID –> Redundant Array of Inexpensive Disks (RAID) is a technology that provides increased storage reliability through redundancy
