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. read more

Having an offsite backup in your RV is great, and after a year of use, I've discovered some ways to make it even better.

Jonathan Corbet wrote a document for inclusion in the kernel tree, describing best practices for merging and rebasing git-based kernel repositories. As he put it, it represented workflows that were actually in current use, and it was a living document that hopefully would be added to and corrected over time.

How to get started using Python's asyncio.

A look into what causes kernel panics and some utilities to help gain more information.

Containerizing the GUI separates your work and play. Virtualization has always been a rich man's game, and more frugal enthusiasts—unable to afford fancy server-class components—often struggle to keep up. Linux provides free high-quality hypervisors, but when you start to throw real workloads at the host, its resources become saturated quickly. No amount of spare RAM shoved into an old Dell desktop is going to remedy this situation. If a properly decked-out host is out of your reach, you might want to consider containers instead.

This article introduces a tool you can use to work on three-dimensional DNA origami. The package is called cadnano, and it's currently being developed at the Wyss Institute. With this package, you'll be able to construct and manipulate the three-dimensional representations of DNA structures, as well as generate publication-quality graphics of your work.

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.

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.
