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

For some teachers, summer is here and thus a long (hopefully, relaxing) break. All the teachers I know are proud lifelong learners, though, and at the end of the summer break there's a new school year awaiting. To help you get the most out of your summer, but also satiate the real need to plan for the coming school year, we've collected some of our favorite concise guides to help you plan. 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.

Throughout the 1980s and into the 1990s, I was primarily a DOS user. I loved the command line environment offered in DOS, which became more powerful with each successive release. I even learned how to write my own DOS programs in the C programming language so I could extend the DOS command line, and write more powerful replacements for the standard DOS commands. I'd experimented with Microsoft's Windows—but if you remember Windows 3 from that time, you know it was slow and tended to crash. But I preferred the command line anyway, so I stuck to DOS. read more

The serverless Java journey started out with functions—small snippets of code running on demand. This phase didn't last long. Although functions based on virtual machine architecture in the 1.0 phase made this paradigm very popular, as the graphic below shows, there were limits around execution time, protocols, and poor local-development experience. read more

A useful feature in almost every command-line environment is the environment variable. Some of these variables allow you to control the behavior or features of the command line, and other variables simply allow you to store data that you might need to reference later. Environment variables are also used in FreeDOS. read more

A faster startup and smaller memory footprint always matter in Kubernetes due to the expense of running thousands of application pods and the cost savings of doing it with fewer worker nodes and other resources. Memory is more important than throughput on containerized microservices on Kubernetes because: read more
