As a systems engineer, I spend a lot of time in data centers configuring servers and other computer equipment. Two of the items I keep in my toolkit are an RS-232 serial-to-USB converter and a standard DB-9 serial cable. These can be indispensable when you have no other way to access a device. You may need to deploy a new router that has not yet been configured for your network. You might need to troubleshoot a firewall appliance that has become inaccessible via SSH. read more

In a recent article, I mentioned my 2020 New Year's resolution: no more loops in Java. In that article, I chose a common (and simplified) forest management calculation—determining whether an area is forested, based on a legal definition, by calculating the proportion of ground shaded by tree canopies. read more

How many iterations does it take to get a container configuration just right? And how long does each iteration take? Well, if you answered "too many times and too long," then my experiences are similar to yours. On the surface, creating a configuration file seems like a straightforward exercise: implement the same steps in a configuration file that you would perform if you were installing the system by hand. Unfortunately, I've found that it usually doesn't quite work that way, and a few "tricks" are handy for such DevOps exercises. read more

A good amount of my day-to-day involves creating, modifying, and deploying Helm charts to manage the deployment of applications. Helm is an application package manager for Kubernetes, which coordinates the download, installation, and deployment of apps. Helm charts are the way we can define an application as a collection of related Kubernetes resources.  read more

Synopsys has found that 99% of commercial software programs include at least one open-source component. But 91% of those included out of date or abandoned open-source code.

Free-as-in-speech software is wildly popular – keeping libraries, components up to date is not. Ninety-one per cent of commercial applications include outdated or abandoned open source components, underscoring the potential vulnerability of organizations using untended code, according to a software review.…

When you deal with a lot of documents every day, whatever you write—whitepapers, manuals, presentations, different marketing materials, contracts, etc.—at a certain point (most commonly, at the final stage) you have to interact with different people, specifying and discussing details, proofreading and approving them.

If you are following the tech news, you might have seen the announcement that ICANN withheld consent for the change of control of the Public Interest Registry and that this …

Have you ever thought about how secure your Linux machine really is? There are numerous Linux distros, each with its own default settings, on which you run dozens of software packages with different version numbers, and numerous services running in the background, which we hardly know or care about. To find the security posture—the overall security status of the software, network, and services running on your Linux machine—you could run a few commands and get bits and pieces of relevant information, but the amount of data you need to parse is huge.

Stuck indoors like most of the rest of the world, a group of Opensource.com editors and correspondents—Seth Kenlon, Matt Broberg, Alan Formy-Duval, Jessica Cherry, and Chris Hermansen—decided to use their far-flung locations and variable-quality internet connections to try out several open source video-conferencing solutions.
