The Linux kernel stack is a tempting target for attack. This is because the kernel needs to keep track of where it is. If a function gets called, which then calls another, which then calls another, the kernel needs to remember the order they were all called, so that each function can return to the function that called it. To do that, the kernel keeps a "stack" of values representing the history of its current context.

Say hello to Plasma 5.16, a the newest iteration of KDE's desktop environment, chock-a-block with new features and improvements.

In only two years, the Linux kernel will be 30 years old. Think about that! Where were you in 1991? Were you even born? I was 13! Between 1991 and 1993 a few "proper" Linux distributions were created, and at least three of them—Slackware, Debian, and Red Hat–provided the backbone the Linux movement was built on. read more

Artificial intelligence (AI) tools and other algorithmic systems are increasingly impacting social, political, and economic structures around us. Simultaneously, and as part of this impact, these systems are increasingly used to inform—or directly make—decisions for policymakers and other institutional leaders. read more

In this tutorial, we will show you how to install and configure the Varnish HTTP accelerator as a reverse proxy for an Apache web server. Varnish is a proxy server focused on HTTP caching. It's designed as an HTTP accelerator and can act as a reverse proxy for your web server.

Markdown is a lightweight markup language that is useful for adding formatting while still maintaining readability when viewing as plain text. Markdown (and Markdown derivatives) are used extensively as the priumary form of markup of documents on services like GitHub and pagure. By design, Markdown is easily created and edited in a text editor, however, […]

Have you ever thought about trying Dungeons & Dragons but didn't know how to start? Did you play Traveller in your youth and have been thinking about returning to the hobby? Are you curious about role-playing games (RPGs) but not sure whether you want to play one? Are you completely new to the concept of tabletop gaming and have never heard of RPGs until now?

How long is your open source story? Did it just begin within the last year? Or have you been a member of the community since before it was called "open source"? We asked our writers to share how long they have been interested in open source. Here are eight stories of how they got started.

News briefs for June 10, 2019.

Kubernetes has two types of objects that can inject configuration data into a container when it starts up: Secrets and ConfigMaps. Secrets and ConfigMaps behave similarly in Kubernetes, both in how they are created and because they can be exposed inside a container as mounted files or volumes or environment variables.

Kubernetes is the de facto open source container orchestration tool for enterprises. It provides application deployment, scaling, container management, and other capabilities, and it enables enterprises to optimize hardware resource utilization and increase production uptime through fault-tolerant functionality at speed. The project was initially developed by Google, which donated the project to the Cloud-Native Computing Foundation.
