Running your container using privileged mode opens up a world of pain if your container is abused. Not only are your host's resources directly accessed with impunity by code within your container (a little like enabling the omnipotent CAP_SYS_ADMIN capability) but you're also relinquishing the cgroups resource limitations which were added to the kernel as a level of protection, too.

Last spring a group I follow on Facebook started sharing information about an oil pipeline, called the Dakota Access Pipeline (DAPL), that was planned to go in the ground in North Dakota, and the Water Protectors, teenagers from the Standing Rock Sioux Reservation who were standing up to try to stop that from happening. As I watched the story unfold over the next few months, I knew that I wanted to go out there and see how the nonprofit organization I work for, Geeks Without Bounds, could help. read more

There's much more to managing a project with git beyond just committing code and working with branches. GitHub-Driven Development is a process that will help you organize and manage the progression of a project on GitHub, although much of this could be applied to other systems, such as GitLab, as well. This concept isn't only for developers; it can be used for project managers or anyone involved in the development of a project—it could even be applied to non-code projects. read more

Dost thou know the Seven Immutable Laws of FP? Stob "Today, object-oriented programming (OOP) rules the IT industry absolutely. It is impossible to dislodge. While functional programming (FP) has seen a resurgence of late, it is typically used as an adjunct to OOP." – Louis Cyphre, 'Why are functional programming languages used so rarely in practice?'…

The Automotive Grade Linux project’s IVI platform will first appear on the 2018 Toyota Camry. Yet, Google poses new competition with “Android Automotive.” The Linux Foundation’s Automotive Grade Linux (AGL) project announced its first design win for its open source, Yocto Project based Unified Code Base (UCB) distribution for in-vehicle infotainment (IVI). The 2018 Toyota […]

Until very recently, 3D printing companies sold only proprietary hardware and materials (including plastic filament) to print with them. This plastic was sold at exorbitant prices (up to hundreds of U.S. dollars per kg), even if it was a common material like ABS (the plastic used for Lego blocks). These companies were following the path of traditional desktop printing companies that rake in large profits selling toner and ink. Some companies still attempt to extort their customers by threatening warranty loss if they use filament from other manufacturers. read more

Personal health information and other sensitive data is left exposed as businesses overlook encryption and network security.

In this article, I'm going to explore perhaps the hardest problem when creating and developing microservices: your data. Using Spring Boot/Dropwizard/Docker doesn't mean you're doing microservices. Taking a hard look at your domain and your data will help you get to microservices. read more

An open organization's culture—the unique ways that you work together as a community—can create a strategic competitive advantage. Red Hat, my home for the last 15 years, was born out of the Linux community. For years, maintaining our open and collaborative culture was relatively simple: We just hired as many open source contributors as we could find, people who already embodied the principles of openness like transparency and collaboration. As the leader of the People team (our HR organization), my job was mostly to make sure we didn't mess the culture up! read more
