  • Red Hat’s David Egts Talks Open-Source Approaches to Digital Transformation

    David Egts, chief technologist of Red Hat's (NYSE: RHT) North American public sector business, has said that open-source procedures can help organizations meet digital transformation goals while promoting mobility and addressing a skills gap.

    In a Fedscoop interview posted Monday, Egts noted that Red Hat’s Open Innovation Labs works with government customers to help them reduce workload processing time through new software development methods.

  • Empowering the open source community

    Red Hat invests heavily in open source communities, offering our employees' time and skills in many upstreams to advance the pace of innovation and support our customers' interests. And when Red Hat purchases a company, it ensures that any proprietary software becomes available as open source. For instance, just this month, Red Hat shared Quay, the formerly proprietary container registry and security scanner software, as an open source upstream available to all.

    [...]

    Awareness of open source in the Middle East is growing in many sectors, particularly in the telecommunications sphere. As operators seek to evolve from physical to digital players, open source ecosystems and solutions are being implemented to optimise and simplify operations, reduce costs, and facilitate digital transformation agendas. From Egypt, Saudi Arabia, and the UAE, to everywhere in between, open source solutions are being unlocked as cost-effective, flexible, reliable, secure, and alternative foundational systems to drive innovation and digital transformation. For telecommunications organisations, open source will enable improved delivery of digital services, the ability to introduce new digital services faster, and the capabilities to leverage insights from data to create new revenue streams.

10 skills every Linux system administrator should have

Filed under
Server

I know what you're saying. You're saying, "Oh, great, someone else telling me that I need soft skills." Yes, that's what I'm telling you. Honing your interviewing skills can not only determine if you get a particular job, it can also be a major factor in the salary you get. It's true. Let's say, for example, that the salary range for a mid-level SA job is $56k to $85k per year. You might be fully qualified for the top of the range, but the company offers you $70k instead and mentions some nonsense about growth potential or they tell you that they'll bring you along when the time is right.

You need to practice answering questions. Answer the question that's asked. Don't give so much information that you see eyes glazing over, but giving answers that are too short will make you appear arrogant or flippant. Give enough examples of your work to let the interviewer(s) know that you know what you're talking about. They can ask for more details if they want to.

You have to learn to watch other people's behaviors. Are they listening to you? Are they focused on you and the interview? Do they look as though you haven't said enough when you pause to allow them to speak or ask another question? Watch and learn. Practice with other system administrators in your group. Do mock interviews with the group. I know it might sound silly, but it's important to be able to speak to other people about what you do. This practice can also be good for you in speaking with managers. Don't get too deep into the weeds with non-technical people. Keep your answers concise and friendly, and offer examples to illustrate your points.

  • Amazon Talks Up Big Performance Gains For Their 7nm Graviton2 CPUs

    If Amazon's numbers are accurate, Graviton2 should deliver a big performance boost for Amazon's ARM Linux cloud potential. Graviton2 processors are 7nm designs making use of Arm Neoverse cores. Amazon says they can deliver up to seven times the performance of current A1 instances, twice the FP performance, and support more memory channels as well as doubling the per-core cache.

  • AWS announces new ARM-based instances with Graviton2 processors

    AWS has been working with operating system vendors and independent software vendors to help them release software that runs on ARM. ARM-based EC2 instances support Amazon Linux 2, Ubuntu, Red Hat, SUSE, Fedora, Debian and FreeBSD. It also works with multiple container services (Docker, Amazon ECS, and Amazon Elastic Kubernetes Service).

  • Coming Soon – Graviton2-Powered General Purpose, Compute-Optimized, & Memory-Optimized EC2 Instances

    We launched the first generation (A1) of Arm-based, Graviton-powered EC2 instances at re:Invent 2018. Since that launch, thousands of our customers have used them to run many different types of scale-out workloads including containerized microservices, web servers, and data/log processing.

  • AWS EC2 6th Gen Arm Instances are 7x Faster thanks to Graviton 2 Arm Neoverse N1 Custom Processor

    Last year Amazon introduced their first 64-bit Arm-based ECS2 “A1” instances which were found to deliver up to 45% cost savings over x86 Instances for the right workloads.

  • AWS launches Braket, its quantum computing service

    With Braket, developers can get started on building quantum algorithms and basic applications and then test them in simulations on AWS, as well as the quantum hardware from its partners. That’s a smart move on AWS’s part, as it’s hedging its bets without incurring the cost of trying to build a quantum computer itself. And for its partners, AWS provides them with the kind of reach that would be hard to achieve otherwise. Developers and researchers, on the other hand, get access to all of these tools through a single interface, making it easier for them to figure out what works best for them.

  • A blueprint for OpenStack and bare metal

    The bare metal cloud is an abstraction layer for the pools of dedicated servers with different capabilities (processing, networking or storage) that can be provisioned and consumed with cloud-like ease and speed. It embraces the orchestration and automation of the cloud and applies them to bare metal workload use cases.

    The benefit to end users is that they get access to the direct hardware processing power of individual servers and are able to provision workloads without the overhead of the virtualization layer—providing the ability to provision environments in an Infrastructure-as-code methodology with separation of tenants and projects.

  • Software Development, Microservices & Container Management – Part III – Why Kubernetes? A Deep Dive into Kubernetes world

  • Content Lifecycle Management in SUSE Manager

    Content Lifecycle management is managing how patches flows through your infra in a staged manner. In ideal infra, latest patches will always be applied on development servers. If everything is good there then those patches will be applied to QA servers and lastly to production servers. This enables sysadmins to catch issues if any and hence preventing patching of prod system which may create downtime of live environments.

    SUSE Manager gives you this control via content lifecycle. In this, you create custom channels in SUSE Manager for example dev, qa and prod. Then you register your systems to those channels according to their criticality. Now whenever channels gets the new patches it will be available to respective systems (registered to those channels) to install. So if you control channels you control the patch availability to systems.

    In content lifecycle management, suse manager enables you to push patches to channels manually. Like on first deploy all latest patches will be available to dev channels and hence dev systems. At this stage, if you run update commands (zypper up, yum update) they will show latest patches only on dev servers. QA and prod servers wont show any new patches.

  • The Early History of Usenet, Part VII: Usenet Growth and B-News

    For quite a while, it looked like my prediction — one to two articles per day — was overly optimistic. By summer, there were only four new sites: Reed College, University of Oklahoma (at least, I think that that's what uucp node uok is), vax135, another Bell Labs machine — and, cruciallyy, U.C. Berkeley, which had a uucp connection to Bell Labs Research and was on the ARPANET.

    In principle, even a slow rate of exponential growth can eventually take over the world. But that assumes that there are no "deaths" that will drive the growth rate negative. That isn't a reasaonable assumption, though. If nothing else, Jim Ellis, Tom Truscott, Steve Daniel, and I all planned to graduate. (We all succeeded in that goal.) If Usenet hadn't shown its worth to our successors by then, they'd have let it wither. For that matter, university faculty or Bell Labs management could have pulled the plug, too. Usenet could easily have died aborning. But the right person at Berkeley did the right thing.

    Mary Horton was then a PhD student there. (After she graduated, she joined Bell Labs; she and I were two of the primary people who brought TCP/IP to the Labs, where it was sometimes known as the "datagram heresy". The phone network was, of course, circuit-switched…) Known to her but unknown to us, there were two non-technical ARPANET mailing lists that would be of great interest to many potential Usenet users, HUMAN-NETS and SF-LOVERS. She set up a gateway that relayed these mailing lists into Usenet groups; these were at some point moved to the fa ("From ARPANET") hierarchy. (For a more detailed telling of this part of the story, see Ronda Hauben's writings.) With an actual traffic source, it was easy to sell folks on the benefits of Usenet. People would have preferred a real ARPANET connection but that was rarely feasible and never something that a student could set up: ARPANET connections were restricted to places that had research contracts with DARPA. The gateway at Berkeley was, eventually, bidirectional for both Usenet and email; this enabled Usenet-style communication between the networks.

Kubernetes: Helm and Gardener Projects

  • Helm Package Manager for Kubernetes Moves Forward

    The official release of version 3.0 of the Helm package manager for Kubernetes is designed to make it easier for IT organizations to discover and securely deploy software on Kubernetes clusters more easily.

    Taylor Thomas, a core contributor to Helm who is also a software developer for Nike, says for the last year the committee that oversees the development of Helm under the auspices of the Cloud Native Computing Foundation (CNCF) has been structuring the package manager to rely more on the application programming interfaces (APIs) that Kubernetes exposes to store records of installation. Helm Charts, which are collections of YAML files describing a related set of Kubernetes resources, now can be rendered on the client, eliminating the need for the Tiller resource management tool resident in the previous release of Helm that ran on the Kubernetes cluster.

    In addition to providing a more secure way to render Helm Charts, Thomas says this approach provides a more streamlined mechanism for packaging software using Helm. Helm 3.0 also updates Helm Charts and associated libraries.
    Additionally, a revamped Helm Go software development kit (SDK) is designed to make Helm more accessible, with the aim of sharing and reusing code the Helm community has open-sourced with the broader Go community, says Thomas.

  • Gardener Project Update

    Last year, we introduced Gardener in the Kubernetes Community Meeting and in a post on the Kubernetes Blog. At SAP, we have been running Gardener for more than two years, and are successfully managing thousands of conformant clusters in various versions on all major hyperscalers as well as in numerous infrastructures and private clouds that typically join an enterprise via acquisitions.

    We are often asked why a handful of dynamically scalable clusters would not suffice. We also started our journey into Kubernetes with a similar mindset. But we realized that applying the architecture and principles of Kubernetes to productive scenarios, our internal and external customers very quickly required the rational separation of concerns and ownership, which in most circumstances led to the use of multiple clusters. Therefore, a scalable and managed Kubernetes as a service solution is often also the basis for adoption. Particularly, when a larger organization runs multiple products on different providers and in different regions, the number of clusters will quickly rise to the hundreds or even thousands.

    Today, we want to give an update on what we have implemented in the past year regarding extensibility and customizability, and what we plan to work on for our next milestone.

  • AMIA encourages NIH to fund FHIR for interoperability and clinical research

    While the FHIR standard is not a cure-all for interoperability challenges, the protocol has seen big momentum in recent years, and is seen as an important bridge between newer mobile devices and hospital networks.

    As a web-based spec that has seen a significant amount of buy-in, the standard could have a large impact on the ability of researchers to access better data.

  • AMIA: FHIR is not suitable for research, needs NIH R&D funding

    According to AMIA, it is critical that NIH assume a leadership position to coordinate a research and development strategy for using FHIR for research and that the agency devote “substantial resources” to the effort.

    Specifically, AMIA recommended that NIH directly fund FHIR research and development through grants; indirectly fund FHIR through special emphasis notices and project requirements that prioritize projects that will use FHIR; and educate the research community and help represent it in activities supported by HL7, the Office of the National Coordinator for Health IT and other standards developing organizations that have an interest in FHIR.

Linux system administration is a job. It can be fun, frustrating, mentally challenging, tedious, and often a great source of accomplishment and an equally great source of burnout. That is to say, it's a job like any other with good days and with bad. Like most system administrators, I have found a balance that works for me. I perform my regular duties with varying levels of automation and manual manipulation and I also do a fair amount of research, which usually ends up as articles. There are two questions I'm going to answer for you in this article. The first is, "How does one become a system administrator?," and second, "What does a Linux system administrator do?".
