In order to get the job you want, or keep the job you like, much focus is often around what experience, certificates, and accreditations you have picked up as a sysadmin. However, once you have the job you want, it isn’t just the hard skills that make you enjoy it. There are also some soft skills that, when applied correctly, can turn your working situation from stressful and uncomfortable to challenging and inspiring. In this article, I focus on the three top soft skills that I believe are most useful for a sysadmin to bring along on the journey towards a great working environment.

Super Blueprints Integrate the 5G Open Source Stack from Core to Door
There is an exciting convergence in the networking industry around open source, and the energy is palpable. At LF Networking, we have a unique perspective as the largest open source initiative in the networking space with the broadest set of projects that make up the diverse and evolving open source networking stack. LF Networking provides platforms and building blocks across the networking industry that enable rapid interoperability, deployment, and adoption and is the nexus for 5G innovation and integration.
LF Networking has now tapped confluence on industry efforts to structure a new initiative to develop 5G Super Blueprints for the ecosystem. Major integrations between the building blocks are now underway–between ONAP and ORAN, Akraino and Magma, Anuket and Kubernetes, and more.
“Super” means that we’re integrating multiple projects, umbrellas (such as LF Edge, Magma, CNCF, O-RAN Alliance, LF Energy, and more) with an end-to-end framework for the underlying infrastructure and application layers across edge, access, and core. This end-to-end integration enables top industry use cases, such as fixed wireless, mobile broadband, private 5G, multi-access, IoT, voice services, network slicing, and more. In short, 5G Super Blueprints are a vehicle to collaborate and create end-to-end 5G solutions.
Major industry verticals banking on this convergence and roadmap include the global telcos that you’d expect, but 5G knows no boundaries, and we’re seeing deep engagement from cloud service providers, enterprise IT, governments, and even energy.
5G is poised to modernize today’s energy grid with awareness monitoring across Distribution Systems and more.
This will roll out in 3 phases, the first encompassing 5G Core + Multi-access Edge Computing (MEC) using emulators. The second phase introduces commercial RANs to end-to-end 5G, and the third phase will integrate Open Radio Access Network (O-RAN).
The 5G Super Blueprint is an open initiative, and participation is open to anyone. To learn more, please see the 5G Super Blueprint FAQ and watch the video, What is the 5G Super Blueprint? from Next Gen Infra.
Participation in this group has tripled over the last few weeks! If you’re ready to join us, please indicate your interest in participation on the 5G Super Blueprint webpage, and follow the onboarding steps on the 5G Super Blueprint Wiki. Send any questions to superblueprint@lfnetworking.org.

Exploring ARM64 runtime patching alternatives
IntroductionSome of today’s modern CPUs come with dedicated instructions to optimize specific operations. For example, ARMv8 has CRC32 instructions to accelerate CRC calculations. The problem is that those instructions can only be executed by a processor that supports them. Although the CPU has a feature register to identify its capabilities, checking the register before executing an instruction is time-consuming. Fortunately, the Linux kernel has…

Learn About Magma, the Open Source Project Bringing High Speed Internet to Remote Areas, in This Free Course
Magma is an open source project supporting diverse radio technologies, including LTE, 5G and WiFi, which can help extend network access into remote, sparsely populated areas. It helps connect the world to a faster network by providing operators an open, flexible, and extendable mobile core network solution. Its operational simplicity and lower cost structure also empower innovators to build fixed and mobile wireless networks never previously imagined.
Magma has already been deployed in production environments. Muralnet, for example, is using Magma to extend network access to Native American communities, while Brisanet has similarly deployed it into remote areas of Brazil. With high speed internet access having huge impacts on regions’ economic fortunes, Magma has the potential to be a game changer around the world.
However, as a relatively new technology, there are not enough individuals with expertise in Magma at present. That’s why Linux Foundation Training & Certification and the Magma Core Foundation have partnered to develop a free, online training course to help technology strategists and decision makers at telcos – as well as rural ISP operators and systems integrators – learn the fundamentals of Magma.
Introduction to Magma: Cloud Native Wireless Networking is designed to provide an understanding of the overall Magma architecture and how it fits into the bigger picture of cellular network architectures, particularly 4G/LTE and 5G. Participants will learn to recognize and understand the main functions of a mobile wireless network, understand the key use cases and value proposition of Magma, the overall architecture of Magma at a functional block level, and the functions performed by each of the main Magma components (Access Gateway, Federation Gateway, and Orchestrator). The course will also provide resources to learn to deploy Magma on standard hardware.
The course was developed by Bruce Davie and Larry Peterson. Davie is a computer scientist noted for his contributions to the field of networking who has served in senior roles at VMware, Software Defined Networking (SDN) startup Nicira, and Cisco. He has over 30 years of networking industry experience. Peterson is the Robert E. Kahn Professor of Computer Science, Emeritus at Princeton University, where he served as Chair from 2003-2009. His research focuses on the design, implementation, and operation of Internet-scale distributed systems, including the widely used PlanetLab and MeasurementLab platforms.
With Magma adoption still in relatively early stages, now is the time for telco and networking professionals to begin learning about this exciting technology. Enroll today!

The GNU Privacy Guard (GPG or gpg) tool is a native/baseos security tool for encrypting files. According to the gpg man page:
gpg is the OpenPGP (Pretty Good Privacy) part of the GNU Privacy Guard (GnuPG). It is a tool to provide digital encryption and signing services using the OpenPGP standard. gpg features complete key management and all the bells and whistles you would expect from a full OpenPGP implementation.

One of the most frequent questions I am asked about rootless Podman is how to debug issues with volumes mounted into the container. This question is deceptively hard. In many ways, running Podman without root is almost identical to running it as root. Unfortunately, this is not always true, and volumes are one of the areas with the most significant differences. Here, I’ll explain in detail what these differences are, what kinds of errors they can cause, and how you can work around them.
