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.

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

If you've tried FreeDOS, you might have been stymied by the command line. The DOS commands are slightly different from how you might use the Linux command line, so getting around on the command line requires learning a few new commands. But it doesn't have to be an "all new" experience for Linux users. We've always included some standard Unix commands in FreeDOS, in addition to the DOS commands that are already similar to Linux. So if you're already familiar with the Linux command line, try these commands to help ease into FreeDOS:

We know that live patching has real benefits because it significantly reduces the downtime associated with frequent patching. But live patching is relatively difficult to achieve without causing other problems and for that reason live patching is not implemented as frequently as it could be. After all, the last thing sysadmins want is a live patch that crashes a system.
