C is a high-level language with close-to-the-metal features that make it seem, at times, more like a portable assembly language than a sibling of Java or Python. Among these features is memory management, which covers an executing program's safe and efficient use of memory. This article goes into the details of memory safety and efficiency through code examples in C and a code segment from the assembly language that a modern C compiler generates.

When you enter a command into your terminal, whether it's to launch a GUI app or just a terminal app, there are often options (sometimes called switches or flags) you can use to modify how the application runs.

A process, in POSIX terminology, is an ongoing event being managed by an operating system’s kernel.

There's a café a few streets away from where I live, and I go there every Sunday for a regularly scheduled game of D&D. They have a menu, and the first few times I ordered, I looked over the menu for several minutes to see what my choices were. Being a creature of habit, I eventually stopped referring to the menu because I knew exactly what they have for sale, and I know exactly what I want. read more

A few days ago, contributors to Opensource.com were asked to share our personal stories about how we got into programming. Many entertaining and fascinating responses were submitted. It would be interesting to quantify these data in time. Intriguing patterns emerged. The 70s generation was nostalgic about Fortran, punch cards, and dial-up access to shared mainframes. 80s kids (amongst which I qualify) shared stories of C, BASIC, or Pascal and their beloved Atari and Commodore computers. Surprisingly few stories from the 90s arrived. Almost like there's a generation gap. read more

When I'm working on projects that require provisioning cloud infrastructure, my workflow has two disparate components: one is infrastructure orchestration, which includes Terraform to bring up the infrastructure (for instance, new EKS clusters), and the second is the provisioning component, which includes Ansible or Bash scripts to instantiate and initialize that infrastructure to accept new deployments (for instance, installing Cluster Autoscaler, kube-state-metrics, and so on.) read more
