  • Red Hat collaborates with NVIDIA to deliver record-breaking STAC-A2 Market Risk benchmark

    We are happy to announce a record-breaking performance with NVIDIA in the STAC-A2 benchmark, affirming Red Hat OpenShift's ability to run compute heavy, high performance workloads. The Securities Technology Analysis Center (STAC®) facilitates a large group of financial firms and technology vendors that produces benchmark standards which enable high-value technology research and testing software for multiple financial applications.

    Red Hat and NVIDIA collaborated to create this latest STAC-A2 entrant, and STAC performed an independent, third-party audit. These are the first public STAC-A2 results using Red Hat OpenShift. Compared to all other publicly reported results to-date, this solution based on Red Hat OpenShift and NVIDIA DGX A100 set several new records for performance metrics and energy efficiency...

  • Improving the performance and space efficiency of SELinux

    Performance is important when it comes to security features such as SELinux. While the performance impact of typical workloads has been long known to be small for most workloads (see for example the SELinux benchmarks of Fedora 31 by Phoronix), certain specific operations are slower than they could be.

    In addition, there are also memory and disk space usage issues, which can lead to unnecessarily large virtual machine images or minimum memory requirements.

    In this post, I will present some of these gaps that I found and fixed upstream. Together, these improvements:

  • Biometric authentication with WebAuthn and SSO

    Providing users with secure, convenient authentication that doesn't rely solely on passwords is a challenge for many application developers and administrators. Passwords can be compromised through leaks, or cracked by malicious intruders, and strong passwords may be too complex for users to remember.

    WebAuthn support in version 7.5 of Red Hat's single sign-on technology (SSO) makes it possible to use biometric data for user authentication. With WebAuthn, users can authenticate using a fingerprint scanner or face recognition, features available in most modern smartphones and laptops.

    This article shows you how to configure Red Hat's SSO to use WebAuthn for biometric user authentication. Our example is based on a JavaScript application built using the React framework, along with the Google WebAuthn emulator.

  • Automating JDK Flight Recorder in containers

    This article is part of a series of hands-on guides to using Cryostat 2.0, or JDK Flight Recorder for containers. This article introduces Cryostat's new API for automated rules. We'll walk through two use cases highlighting the API's compact but powerful rule definitions. You'll see how to use rule definitions to specify a match expression for one or more target Java applications, and how to configure the type of flight recording you want to start on these targets.

    Once you've created a rule, Cryostat immediately matches it against all existing discovered targets and starts your flight recording. Cryostat will also apply the rule to newly discovered targets that match its definition. You can create multiple rules to match different subsets of targets or to layer different recording options for your needs.

    The automated rules API is brand new in Cryostat 2.0, and we haven't yet developed the user interface (UI) for it. For now, we'll use curl to interact with the Cryostat HTTP API directly.

  • 4 realities IT leaders should know about remote developers now

    The pandemic brought a lot of change in the way teams interact with each other. Along with many workers being forced into home office setups came new challenges – with communication, remote workstation access, and cybersecurity (now of heightened importance). Hopefully, by now your organization has figured out a way to support remote work. But this isn’t temporary; a more distributed and remote-capable workforce is where things are headed.

    As IT leaders think about remote and hybrid models of work for teams, and adopt tools for virtual meetings and file sharing, it’s vital to consider the individual needs of a valuable team role - the developer. Here are a four factors to consider:

  • 3 essential soft skills IT pros need

    IT continues to be one of the fastest-growing employment sectors. However, as remote work environments become increasingly common and technology becomes further intertwined with other business functions, the role of the IT professional is evolving.

    As today’s IT professionals engage with more colleagues throughout the business, their skills must extend well beyond technical expertise. Over 40 percent of respondents to a recent study by West Monroe admitted encountering IT professionals who struggle with collaboration, hampering productivity. As a result, hiring managers are looking for IT prospects with comprehensive soft skills to add greater value to their business.

What is a technical marketing manager?

  • What is a technical marketing manager?

    First off, from one organization to the next, there will be different names for these roles and different alignments of responsibilities. Red Hat is a unique company with a unique culture, so this may not represent how technical marketing works in your organization.

    My work revolves around three roles: product marketer (PMM), technical marketing manager (TMM), and product manager (PM).

    Product managers work as a lead for their product or feature. They help write features with engineering, cast vision for their roadmap, and work with marketing to build a story that ties the market problem together with the component designed to fix it.

    Product marketers help define the message: Why would an organization care about the feature we are building? What business problems do we need to address? I'll leave a more in-depth overview of these roles to others, but in short, that is their purview.

  • 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.
