  • Red Hat technologies make open hybrid cloud a reality

    It’s important to make the distinction between open hybrid cloud and multi-cloud environments. A hybrid cloud features coordination between the tasks running in the different environments. Multi-cloud, on the other hand, simply uses different clouds without coordinating or orchestrating tasks among them.

    Red Hat solutions are certified on all major cloud providers, including Alibaba Cloud, Amazon Web Services, the Google Cloud Platform, IBM Cloud, and Microsoft Azure. As you’re defining your hybrid cloud strategy, you can be confident that you won’t be going it alone as you work with a cloud provider. You won’t be the first person to try things on Cloud x; you’ll have the promise of a proven provider that works with your hybrid architecture.

  • Successful OpenShift 4.1 Disconnected install

    My new position has me working with Red Hat customers in the financial services industry. These customers have strict regulations for controlling access to machines. When it comes to installing OpenShift, we often are deploying into an environment that we call “Air Gapped.” What this means in practice is that all install media need to be present inside the data center, and cannot be fetched from online on demand. This approach is at odds with the conveniences of doing an on-demand repository pull of a container image. Most of the effort involves setting up intern registries and repositories, and getting X509 certificates properly created and deployed to make access to those repositories secure.

    The biggest things we learned is that automation counts. When you need to modify a file, take the time to automate how you modify it. That way, when you need to do it again (which you will) you don’t make a mistake in the modification. In our case, we were following a step-by-step document that got us about halfway through before we realized we made a mistake. Once we switched from manual edits to automated, we were far more likely to rollback to a VM snapshot and roll forward to make progress. At this point, things really started getting smoother.

  • NEST 2.18.0 (and 2.16.0) are ready for use on NeuroFedora

  • Capture and playback UDP packets

    Generating some random statsd communication is easy, it’s text-based UDP protocol and all you need to have is netcat. However things change when statsd server is integrated with real application flodding it with thousands of packets of various attributes.

  • Apache Hive vs. Apache HBase: Which is the query performance champion?

    It's super easy to get lost in the world of big data technologies. There are so many of them that it seems a day never passes without the advent of a new one. Still, such fast development is only half the trouble. The real problem is that it's difficult to understand the functionality and the intended use of the existing technologies.

    To find out what technology suits their needs, IT managers often contrast them. We've also conducted an academic study to make a clear distinction between Apache Hive and Apache HBase—two important technologies that are frequently used in Hadoop implementation projects.

  • Geeking outside the office

    Sysadmins have plush, easy desk jobs, right? We sit in a nice climate-controlled office and type away in our terminals, never really forced to exert ourselves. At least, it might look that way. As I write this during a heat wave here in my hometown, I'm certainly grateful for my air-conditioned office.

    Being a sysadmin, though, carries a lot of stress that people don't see. Most sysadmins have some level of on call. In some, places it's a rotation. In others, it's 24/7. That's because some industries demand a quick response, and others maybe a little less. We're also expected to know everything and solve problems quickly. I could write a whole separate article on how keeping calm in an emergency is a pillar of a good sysadmin.

    The point I'm trying to make is that we are, in fact, under a lot of pressure, and we need to keep it together. While in some cases profit margins are at stake, in other cases lives could be. Let's face it, in this digital world almost everything depends on a sysadmin to keep the lights on. Maintaining all of this infrastructure pushes many sysadmins (and network admins, and especially information security professionals) to the brink of burnout.

    So, this article addresses how getting away from the day job can help you keep your sanity.

  • Rook v1.0 Adds Support for Ceph Nautilus, EdgeFS, and NFS Operator

    Rook, a storage orchestrator for Kubernetes, has released version 1.0 for production-ready workloads that use file, block, and object storage in containers. Highlights of Rook 1.0 include support for storage providers through operators like Ceph Nautilus, EdgeFS, and NFS. For instance, when a pod requests an NFS file system, Rook can provision it without any manual intervention.

    Rook was the first storage project accepted into the Cloud Native Computing Foundation (CNCF), and it helps storage administrators to automate everyday tasks like provisioning, configuration, disaster recovery, deployment, and upgrading storage providers. Rook turns a distributed file system into storage services that scale and heal automatically by leveraging the Kubernetes features with the operator pattern. When administrators use Rook with a storage provider like Ceph, they only have to worry about declaring the desired state of the cluster and the operator will be responsible for setting up and configuring the storage layer in the cluster.

  • Open-Source Project Unveils Detailed Road Map for New Mainnet

    An open-source project that aims to create a smart economy based on blockchain technology has unveiled a new program designed to fuel its ecosystem’s growth — while setting out a detailed road map for its new mainnet. Neo says its EcoBoost scheme has been designed to support developers and projects that are already in its ecosystem, as well as those that wish to join. A total of $100 million has been allocated to the initiative — and in the first phase, the firm is seeking to establish long-term partnerships that will fuel the organic growth of its network. Media outlets, exchanges, decentralized application (DApp) distribution platforms and other blockchain infrastructures are being encouraged to express an interest in becoming an EcoBoost Partner, and Neo says it has already received numerous applications from “leading institutions and projects in the industry.”

  • 5 Arenas Where Open Source is the Undisputed Champion

    Open source software has come of age. It has now reached a level of maturity and capability where it simply cannot be ignored. Recent research[1] suggests that 82 percent of large organizations are more receptive to open source than they were five years ago and that C-level IT executives are now most likely to prefer an open source solution over proprietary alternatives. Over the years, everyone’s confidence and trust in open source software has been steadily growing. We’ve now reached the point where open source is the dominant player in many of the key technology trends shaping our world. [...] It’s widely acknowledged that Linux is the power behind the vast majority of public internet servers and that Unix-like operating systems are being used by about 70 percent of all web servers, with Linux taking the lion’s share. Why is that important?  Because even though we pay them little thought or attention, web and internet servers are responsible for stitching together the digital fabric that most of us rely on for communications and services every day. [...] There’s no denying that open source is here to stay.  I’ve been working with open source for almost a decade now and over that time I’ve seen how quickly open source solutions have taken off, gained acceptance and become the front runner is so many areas.

  • U-Boot Has Been Seeing Better x86 Support, EFI Improvements

    Google's Simon Glass who is part of the Chromium / Chrome OS team presented at this week's Embedded Linux Conference in San Diego on U-Boot.  U-Boot continues making good progress particularly on the embedded front for where this bootloader is most well known, but it's also been seeing increasing x86 support. Currently U-Boot supports around 10 different Intel SoCs and can handle booting from Coreboot on most boards. Intel Apollolake support is forthcoming to U-Boot. Additionally, FSP2 support for the newer version of Intel's firmware support package is being worked on for U-Boot. Also new on U-Boot's x86 front is slimbootloader support. 

  • Dustin J. Mitchell: Outreachy Round 20

    Outreachy is a program that provides paid internships working on FOSS (Free and Open Source Software) to applicants from around the world. Internships are three months long and involve deep, technical work on a mentor-selected project, guided by mentors and other developers working on the FOSS application. At Mozilla, projects include work on Firefox itself, development of associated services and sites like Taskcluster and Treeherder, and analysis of Firefox telemetry data from a data-science perspective. The program has an explicit focus on diversity: “Anyone who faces under-representation, systemic bias, or discrimination in the technology industry of their country is invited to apply.” It’s a small but very effective step in achieving better representation in this field. One of the interesting side-effects is that the program sees a number of career-changing participants. These people bring a wealth of interesting and valuable perspectives, but face challenges in a field where many have been programming since they were young.

  • First‑of‑its‑kind spyware sneaks into Google Play
  • Open-source spyware bypasses Google Play defenses — twice

    Radio Balouch — the app in question — is a legitimate radio application serving Balouchi music enthusiasts, except that it also included AhMyth, a remote access espionage tool that has been available on GitHub as an open-source project since late 2017. Lukas Stefanko, ESET researcher who uncovered the campaign, said the app was uploaded twice on Google Play — once on July 2 and a second time on July 13 — only to be swiftly removed by Google within 24 hours upon being alerted by the security team. It continues to be available on third-party app stores. While the service’s dedicated website “radiobalouch.com” is no longer accessible, the attackers also seem to have promoted the app on Instagram and YouTube. The app, in total, attracted over 100 installs.
