What is DevOps? How does it relate to other ideas and methodologies within software development? Linux Journal Deputy Editor and longtime software developer, Bryan Lunduke isn't entirely sure, so he asks some experts to help him better understand the DevOps phenomenon. The word DevOps confuses me.

The internet has a sustainability problem. Many of its critical services depend on the dedication of unpaid volunteers, because they can't be monetized and thus don't have any revenue stream for the maintainers to live on. I'm talking about services like DNS, time synchronization, crypto libraries—software without which the net and the browser you're using couldn't function.

IMPORTANT NOTICE FROM LINUX JOURNAL, LLC: On August 7, 2019, Linux Journal shut its doors for good.

David Howells put in quite a bit of work on a script, ./scripts/syscall-manage.pl, to simplify the entire process of changing the system call tables. With this script, it was a simple matter to add, remove, rename or renumber any system call you liked. The script also would resolve git conflicts, in the event that two repositories renumbered the system calls in conflicting ways.

Hands On Container wunderkind Docker has released a preview of Docker Desktop for Windows Subsystem for Linux 2. This peek at Docker Desktop 2 is based on the work Microsoft has done to make Windows Subsystem for Linux a full virtual machine (VM) with its own complete Linux kernel, instead of redirecting system calls as is done in the first version of WSL. This means that the docker daemon can run in WSL rather than in a separate Hyper-V VM.

The original UNIX operating system was created, in large part, to facilitate porting a video game to a different computer. And, without UNIX, we wouldn't have Linux, which means we owe the very existence of Linux to...video games. It's crazy, but it's true.

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." read more

When a platform exclusive game is announced, for Windows users this is the difference between buying/playing via one store or launcher vs. another, but for a Linux user, it's a whole other bag.

Investigative journalist Tim Verheyden, who broke the story on how Google employees listen to people’s audio recordings, explains in an interview how he got hold of the story, why he is now using the encrypted contact form Secure Connect by Tutanota and why the growing number of "ghost workers" in and around Silicon Valley is becoming a big issue in Tech.

If you've written any amount of bash code, you've likely come across the trap command. Trap allows you to catch signals and execute code when they occur. Signals are asynchronous notifications that are sent to your script when certain events occur. Most of these notifications are for events that you hope never happen, such as an invalid memory access or a bad system call. However, there are one or two events that you might reasonably want to deal with...

The jargonized new name means "Day 2 IQ," with Day 2 being a DevOps term that refers to the operations part of the software development lifecycle and with IQ equating to "smart."

There are several different ways to remove directories in Linux systems.

But, if you are working on a headless server or want to remove multiple directories at once your best option is to delete the directories (folders) from the command line.
