IBM/Red Hat: Security Enhanced Linux, Open Data Hub and More

Submitted by Roy Schestowitz on Wednesday 3rd of June 2020 01:42:25 AM
  • SELinux Sees Nice Optimizations With Linux 5.8

    Security Enhanced Linux is seeing some nice optimizations with the in-development Linux 5.8 kernel.

    One of the optimizations in Linux 5.8 for SELinux is changing around some of their internal data structures for improving performance. One notable area is using a hash table for SELinux role transitions. For storing role transitions within a hash table, on Fedora where there are around 428 role transitions, the run-time was cut by about 50% when testing with Stress-NG benchmarks.

  • [Red Hat] Edge investments, data navigators, and more industry trends

    As part of my role as a senior product marketing manager at an enterprise software company with an open source development model, I publish a regular update about open source community, market, and industry trends for product marketers, managers, and other influencers. Here are five of my and their favorite articles from that update.

  • Open Data Hub 0.6.1: Bug fix release to smooth out redesign regressions

    It is just a few short weeks since we released Open Data Hub (ODH) 0.6.0, bringing many changes to the underlying architecture and some new features. We found a few issues in this new version with the Kubeflow Operator and a few regressions that came in with the new JupyterHub updates. To make sure your experience with ODH 0.6 does not suffer because we wanted to release early, we offer a new (mostly) bugfix release: Open Data Hub 0.6.1.

  • Open Sourcing Red Hat Advanced Cluster Management for Kubernetes

    Recently, at Red Hat Summit Virtual Event, we announced Red Hat Advanced Cluster Management for Kubernetes, a new management solution designed to help organizations further extend and scale Red Hat OpenShift, the leading enterprise Kubernetes platform.

    This new product is based on technology that originated with IBM, and that technology was not fully open source. In accordance with Red Hat policy, we are in the process of opening the source code for this new product. This same open source technology will then also be used by IBM for its CloudPak for Multicloud Management. At Red Hat, we believe using an open development model helps create more secure, stable and innovative technologies. And the commitment to that open source model is what we have based our business model on. Even after joining forces with IBM, this commitment remains unchanged. We have worked more than 25 years to invest in open projects and technologies.

  • Role of APIs in an increasingly digital world

    COVID-19 has had a major impact on the world. It has affected the way we do business, where we work, how we provide services and how we communicate. We must find new ways to accomplish these pursuits, and application programming interfaces (APIs) can help.

    In a digital-driven world, applications have become fundamental to our economy and even our society – and these applications commonly need to communicate and integrate with a range of other applications and systems in order to perform their essential functions. APIs are one way to unlock the change.

  • RHEL 7.8 and the final update to container tools

    Before we get started with the updates for Red Hat Enterprise Linux 7.8, we recommend taking a serious look at moving to Red Hat Enterprise Linux 8. RHEL 7 is now in Maintenance Support and will no longer receive newer versions of container tools. Users who need access to the latest versions of Podman, Buildah and Skopeo, should move to RHEL 8 where the container-tools module is updated once a quarter. For those of you required to use containers on RHEL 7, this post will provide you a strategic and technical update.

    Red Hat understands that many customers cannot upgrade immediately. So, similar to our update of container tools in RHEL 7.7, we have released one final update to the container tools provided in RHEL 7.8.

  • Advancing open source in telecom demands interoperability: How do we get there?

    More and more, open source technologies are gaining traction in the telecommunications industry as service providers reinvent their networks and push the boundaries with cloud-native networking functions and principles. But challenges remain, in particular around integration and interoperability of the many components that make up their infrastructures.

    This was a central theme at the Open Networking Summit Europe in Antwerp, Belgium, an event focused on the future of open source networking and aimed at enabling collaborative development and innovation across enterprises, service providers, and cloud providers.

    As digital service providers begin realizing value from open source platforms like OpenStack – including faster time to market, reduced costs, and improved reliability, scalability, and agility – they are in a better position to deliver the services their customers want: mobile 5G streaming video, audio, and more.

  • Exploring and modeling COVID data

    “If your prediction proves to be very good, then it’s probably too good to be true,” says IBM developer advocate and data scientist Damiaan Zwietering.

    Damiaan loves his profession, which he has been practicing for almost 25 years, and by now he has come across most of the pitfalls. He likes to share his knowledge and experience with others, from developers to people in the business, and therefore, has a prominent role during the June 12, 2020, Code @ Think digital event. To register for this event, click here.

    In two sessions, he’ll introduce anyone who wants to know more about data science into the world of COVID-19 data and where the opportunities and pitfalls lie.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
