Copying files in Linux

ven, 08/09/2019 - 09:02

Copying documents used to require a dedicated staff member in offices, and then a dedicated machine. Today, copying is a task computer users do without a second thought. Copying data on a computer is so trivial that copies are made without you realizing it, such as when dragging a file to an external drive.

Mutation testing is the evolution of TDD

ven, 08/09/2019 - 09:01

In "Failure is a feature in blameless DevOps," I discussed the central role of failure in delivering quality by soliciting feedback. This is the failure agile DevOps teams rely on to guide them and drive development. Test-driven development (TDD) is the conditio sine qua non of any agile DevOps value stream delivery.

Goodbye, Linux Journal

ven, 08/09/2019 - 09:00

I first discovered Linux in 1993, when I was an undergraduate physics student who wanted the power of Big Unix on my home PC. I remember installing my first Linux distribution, SoftLanding Systems (SLS), and exploring the power of Linux on my ‘386 PC. I was immediately impressed. Since then, I’ve run Linux at home—and even at work.

Markdown beginner's cheat sheet

jeu, 08/08/2019 - 09:01

Markdown is a widely adopted plain-text formatting syntax used to specify HTML rendering. It is also an essential skill to learn if you want to contribute to open source software. 

Like many concepts in open source communities, there are multiple, domain-specific distributions of Markdown. CommonMark provides an unambiguous rendering specification for defined Markdown incantations while many communities offer extensions to the official specification.

Scrum vs. kanban: Which agile methodology is better?

jeu, 08/08/2019 - 09:00

Because scrum and kanban both fall under the agile methodology umbrella, many people confuse them or think they're the same thing. There are differences, however. For one, scrum is more specific to software development teams, while kanban is used by many kinds of teams and focuses on providing a visual representation of an agile team's workflow. Some argue that kanban is about getting things done, and scrum is about talking about getting things done.

Navigating the Bash shell with pushd and popd

mer, 08/07/2019 - 09:02

The pushd and popd commands are built-in features of the Bash shell to help you "bookmark" directories for quick navigation between locations on your hard drive. You might already feel that the terminal is an impossibly fast way to navigate your computer; in just a few key presses, you can go anywhere on your hard drive, attached storage, or network share. But that speed can break down when you find yourself going back and forth between directories, or when you get "lost" within your filesystem.

Why fear of failure is a silent DevOps virus

mer, 08/07/2019 - 09:00

Do you recognize the following scenario? I do, because a manager once stifled my passion and innovation to the point I was anxious to make decisions, take risks, and focus on what's important: "uncovering better ways of developing software by doing it and helping others do it" (Agile Manifesto, 2001).

Developer: "The UX hypothesis failed. Users did not respond well to the new navigation experience, resulting in 80% of users switching back to the classic navigation."

Unboxing the Raspberry Pi 4

mar, 08/06/2019 - 09:03

When the Raspberry Pi 4 was announced at the end of June, I wasted no time. I ordered two Raspberry Pi 4 Starter Kits the same day from CanaKit. The 1GB RAM version was available right away, but the 4GB version wouldn't ship until July 19th. Since I wanted to try both, I ordered them to be shipped together.

Avoiding burnout: 4 considerations for a more energetic organization

mar, 08/06/2019 - 09:00

In both personal and organizational life, energy levels are important. This is no less true of open organizations. Consider this: When you're tired, you'll have trouble adapting when challenges arise. When your energy is low, you'll have trouble collaborating with others. When you're feeling fatigued, building and energizing an open organization community is difficult.

Navigating the filesystem with relative paths at the command line

lun, 08/05/2019 - 09:02

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. Instead, you use a relative path.

Back then, the thought of releasing source code anyone could change scared many commercial software vendors.

Understanding file paths and how to use them in Linux

ven, 08/02/2019 - 09:02

A file path is the human-readable representation of a file or folder’s location on a computer system. You’ve seen file paths, although you may not realize it, on the internet: An internet URL, despite ancient battles fought by proprietary companies like AOL and CompuServe, is actually just a path to a (sometimes dynamically created) file on someone else’s computer.
