  • Red Hat Expands the Kubernetes Developer Experience with Newest Version of Red Hat OpenShift 4

    Red Hat, Inc., the world's leading provider of open source solutions, today announced Red Hat OpenShift 4.2, the latest version of Red Hat’s trusted enterprise Kubernetes platform designed to deliver a more powerful developer experience. Red Hat OpenShift 4.2 extends Red Hat’s commitment to simplifying and automating enterprise-grade services across the hybrid cloud while empowering developers to innovate and enhance business value through cloud-native applications.

  • RHEL and Insights combo illuminates threats and spotlights performance for Red Hat systems

    When Red Hat Inc. officially rolled out its Red Hat Enterprise Linux 8, or RHEL 8, operating system in May, the open-source software company also included Red Hat Insights with every subscription for the new release. Based on data supplied by one of the company’s top executives, that has proven to be a wise decision.

    Insights is a software as a service product that works from a rules-based engine to offer continuous connected analysis of registered Red Hat-based systems.

    “We’ve seen an 87% increase since May in the number of systems that are linked in,” said Stefanie Chiras (pictured), vice president and general manager of the RHEL Business Unit at Red Hat. “We’re seeing a 33% increase in coverage of rules-based and a 152% increase in customers who are using it. That creates a community of people using and getting value from it, but also giving value back because the more data we have the better the rules get.”

  • What’s new in Red Hat Dependency Analytics

    We are excited to announce a new release of Red Hat Dependency Analytics, a solution that enables developers to create better applications by evaluating and adding high-quality open source components, directly from their IDE.

    Red Hat Dependency Analytics helps your development team avoid security and licensing issues when building your applications. It plugs into the developer’s IDE, automatically analyzes your software composition, and provides recommendations to address security holes and licensing problems that your team may be missing.

    Without further ado, let’s jump into the new capabilities offered in this release. This release includes a new version of the IDE plugin and the server-side analysis service hosted by Red Hat.

  • Breaking cloud native network performance barriers

    Up until now we have covered virtio-networking and its usage in VMs. We started with the original vhost-net/virtio-net architecture, moved on to the vhost-user/virito-pmd architecture and continued to vDPA (vHost Data Path Acceleration) where the virtio ring layout was pushed all the way into the NIC providing wiresspeed/wirelatency to VMs.

    We now turn our attention to using vDPA for providing wirespeed/wirelatency L2 interfaces to containers leveraging kubernetes to orchestrate the overall solution. We will demonstrate how Containerized Network Functions (CNFs) can be accelerated using a combination of vDPA interfaces and DPDK libraries. The vDPA interfaces are added as a secondary interface to containers using the Multus CNI plugin.

    This post is a high level solution overview describing the main building blocks and how they fit together. We assume that the reader has an overall understanding of Kubernetes, the Container Network Interface (CNI) and NFV terminology such as VNFs and CNFs.

  • The Potential Of Red Hat Plus Power Is Larger Than Exascale

    Red Hat is coming onto IBM’s books at just the right time, and to be honest, it might have been better for Big Blue if the deal to acquire the world’s largest supplier of support and packaging services for open source software had closed maybe one or two quarters ago.

    IBM was at the tail end of one mainframe cycle and at the beginning of a new one during the third quarter of 2019, and was up against a very tough compare in its Power Systems business as well. And as a consequence, despite some pretty healthy growth in its services and consulting businesses and a partial quarter of revenues and profits from its Red Hat division, IBM nonetheless had sales contract by 3.9 percent to just a tad over $18 billion in the quarter ended in September, and more surprisingly, net income was down by 37.9 percent to $1.67 billion as costs across all fronts – sales, administrative, research, development – all rose by 17 percent to $6.58 billion at the same time that intellectual property revenues (which are almost pure profit) fell by 39.6 percent to $166 million.

    To its credit, IBM is investing in its future and is gung-ho about its transaction processing systems based on Power and System z processors as well as its prospects in the coming years with HPC and AI systems based on Power processors and any number of different kinds of accelerators. This, despite not winning either of the two CORAL-2 exascale system awards with the US Department of Energy at Oak Ridge National Laboratory and Lawrence Livermore National Laboratory, where IBM’s GPU-accelerated Power9 systems – “Summit” at Oak Ridge and “Sierra” and Lawrence Livermore – are the pre-exascale incumbents. The Summit and Sierra deals were contracted at $325 million, which is a big chunk of change for any vendor, and the two exascale systems that replace them – “Frontier” at Oak Ridge and “El Capitan” at Lawrence Livermore – are together accounting for around $1 billion in system acquisitions and another $200 million or so in non-recurring engineering (NRE) costs. Those deals did not impact IBM’s books her in 2019, but the fact that IBM did not win either deal will absolutely have a downdraft effect on its revenues in 2022 and 2023, when these two machines are expected to be accepted by their respective labs and therefore generating revenues.

OpenShift 4.2: Console customization

  • OpenShift 4.2: Console customization

    In Openshift 4, we built a brand new UI(Console) from the ground up with the goal in mind of keeping it simple, while still giving admins the ability to customize and extend it for their needs.

  • Faster Winter 4: Export lists

    Without an export, the compiler has to assume that every top-level function can possibly called from the outside, even functions that you think of as “internal”. If you have a function that you do not export, like instr, step_work and step after my change, the compiler can see all the places the function is called. If the function is only called in one place, it may inline it (copy its definition into where it is called), and simplify the code around the edges. And even if it does not inline the function, it might learn something about how the functions are used, and optimize them based on that (e.g. based on Demand Analysis).

  • Ondřej Holý: How to call asynchronous function synchronously

    GLib provides a lot of asynchronous functions, especially to deal with I/O. Unfortunately, some functions don’t have synchronous equivalents and the code has to be split into several callbacks. This is not handy in some cases. My this year’s GSoC student recently asked me whether it is possible to create synchronous function from asynchronous. He is currently working on test suite and don’t want to split test cases into several callbacks. So I decided to write a blog spot about as it might be handy for more people.

  • Sort list alphabetically with python

    You will be given a vector of string(s). You must sort it alphabetically (case-sensitive!!) and then return the first value. The returned value must be a string and have “***” between each of its letters. You should not remove or add elements from/to the array. Above is another problem in codewars, besides asking us to sort the array list and returning the first value in that list, we also need to insert stars within the characters.

  • Abolishing SyntaxError: invalid syntax ...

    Do you remember when you first started programming (possibly with Python) and encountered an error message that completely baffled you? For some reason, perhaps because you were required to complete a formal course or because you were naturally persistent, you didn't let such messages discourage you entirely and you persevered. And now, whenever you see such cryptic error messages, you can almost immediately decipher them and figure out what causes them and fix the problem. Congratulations, you are part of an elite group! Even a large number of people who claim that they can program are almost certainly less capable than you are. Given your good fortune, would you mind donating 5 to 10 minutes of your time to help countless beginners that are struggling in trying to understand Python error messages?

  • Is it too late to integrate GitOps?

    The idiom “missed the boat” can be used to describe the loss of an opportunity or a chance to do something. With OpenShift, the excitement to use this new and cool product immediately may create your own “missed the boat” moment in regards to managing and maintaining deployments, routes, and other OpenShift objects but what if the opportunity isn’t completely gone? Continuing with our series on GitOps (LINK), the following article will walk through the process of migrating an application and its resources that were created manually to a process in which a GitOps tool manages the assets. To help us understand the process we will manually deploy a httpd application. Using the steps below we will create a namespace, deployment, and service and expose the service which will create a route.
