Navigating the filesystem with relative paths at the command line

Mon, 08/05/2019 - 15:02

If you’re on your way to work, but you stop by a deli for breakfast first, you don’t go back home after breakfast so you can restart your journey. Instead, you continue from where you are because you understand where your office is located relative to your current location. Navigating your computer is the same way. If you change your working directory in a terminal to a subdirectory, such as Pictures, you don’t necessarily have to go home again just to make your way into Documents.

Understanding file paths and how to use them in Linux

Fri, 08/02/2019 - 15:02

A file path is the human-readable representation of a file or folder’s location on a computer system.

Fri, 08/02/2019 - 15:01

While science is supposed to be about building on each other's findings to improve our understanding of the world around us, reproducing and reusing previously published results remains challenging, even in the age of the internet.

Failure is a feature in blameless DevOps

Thu, 08/01/2019 - 15:00

DevOps is just another term for value stream development. What does value stream mean?

Value is what arises during our interactions with customers and stakeholders. Once we get into value stream development, we quickly realize that value is not an entity. Value constantly changes. Value is a process. Value is a flow.

Hence the term stream. Value is only value if it's a stream. And this streaming of value is what we call continuous integration (CI).
