Preparing to run a new (or convert an existing) application in Kubernetes takes work. Working with Kubernetes requires defining and creating multiple "manifests" for the different types of objects in your application. Even a simple microservice is likely to have a deployment.yaml, service.yaml, configmap.yaml, and other files. These declarative YAML files for Kubernetes are usually known as "manifests." You might also have to set up secrets, ingresses, persistent volumes, and other supporting pieces.

Detecting vulnerabilities and managing the associated patching is challenging even in a small-scale Linux environment. Scale things up and the challenge becomes almost unsurmountable. There are approaches that help, but these approaches are unevenly applied. In our survey, State of Enterprise Vulnerability Detection and Patch Management, we set out to investigate how large organizations handle the dual, linked security concerns of vulnerability detection and patch management.

The Linux Foundation Public Health is releasing the infrastructure for the first international COVID-19 passport. It's being considered for use by both the United Nations and the European Union.

One thing I appreciate from growing up with DOS computers is that the boot process is relatively easy to understand. There aren't a lot of moving parts in DOS. And today, I'd like to share an overview of how your computer boots up and starts a simple operating system like FreeDOS. read more

Compiling source code produces a binary. During compilation, you can provide flags to the compiler to enable or disable certain properties on the binary. Some of these properties are relevant to security. Checksec is a nifty little tool (and shell script) that, among other functions, identifies the security properties that were built into a binary when it was compiled. A compiler might enable some of these properties by default, and you might have to provide specific flags to enable others. read more

Even if you haven't used DOS before, you are probably aware of its command-line shell, named simply COMMAND.COM. The COMMAND.COM shell has become synonymous with DOS, and so it's no surprise that FreeDOS also implements a similar shell called "FreeCOM"—but named COMMAND.COM just as on other DOS systems. read more

Kubernetes, the de facto standard for container orchestration, has quickly grown to dominate the container environment both in terms of infrastructure management and application development. As an open source platform with a huge community of enthusiasts and professionals, and being a part of the Cloud Native Computing Foundation, Kubernetes has become not only a powerful and impressive orchestration system itself but it has fostered a huge ecosystem of related tools and services to make it easier to use and extend its functionality with ever more powerful and sophisticated components. read more

I am a control freak. I like to be in control. I got my pilot’s license so I could fly an airplane for fun, but it also helped me understand what is happening when I fly commercial. So now I find myself explaining to other travelers that, while not a normal occurrence, landing with the malfunctioning flaps in the up position is something that all pilots train extensively for. Yes, that is something that happened to my wife and me on a commercial flight a couple of years ago.

Maintaining open-source code is a vital but stressful job. Despite that, a recent Tidelift survey found that almost half of code maintainers aren't paid at all.
