  • 3 solid self-review tips for sysadmins | Enable Sysadmin

    At every job I’ve held, the general opinion about self-reviews tends to fall into one of two categories. Either employees view them as arduous and frustrating or they simply don’t care about them. However, I believe that a well-written self-review can help you accelerate your career, whether your goal is a raise, a promotion, or merely some well-deserved recognition for your efforts. In this article, I’ll discuss my approach to performance reviews. While there is no one-size-fits-all strategy, this approach has served me well through several organizations and positions.

  • Red Hat OpenShift drives a strong 5G open RAN ecosystem

    As the telecommunications industry ramps up its evolution towards cloud-native architectures and containers, communications service providers (CSPs) are working to scale their networks to support increased demand. In this effort, open radio access network (RAN) solutions offer standardized disaggregation of the RAN, decoupling hardware and software, to give CSPs more freedom of choice. Many organizations are looking to implement a container platform like Red Hat OpenShift that is ready to take on the intensive demands of this evolution for their RAN and for new 5G use cases, such as network slicing, IoT and industrial IoT. Moving to a cloud-native platform creates the opportunity for many of them to work with new suppliers, boost innovation and better differentiate using new operating models.

    Red Hat is excited to play a key role in this transformation. Last year, we shared the news of our expanded collaboration with Altiostar to develop an infrastructure and workload automation framework for a container-based RAN reference architecture that allows a consistent approach to a disaggregated RAN for both our customer and partner ecosystem. We’re now excited to build on this momentum by extending our architecture in collaboration with Mavenir, to transform mobile network infrastructures.

  • AIOps vs. MLOps: What's the difference?

    In late 2019, O'Reilly hosted a survey on artificial intelligence (AI) adoption in the enterprise. The survey broke respondents into two stages of adoption: Mature and Evaluation.

    When asked what's holding back their AI adoption, those in the latter category most often cited company culture. Trouble identifying good use cases for AI wasn't far behind.

  • Debuginfod project update: New clients and metrics - Red Hat Developer

    It’s been about a year since our last update about debuginfod, an HTTP file server that serves debugging resources to debugger-like tools. Since then, we’ve been busy integrating clients across a range of developer tools and improving the server’s available metrics. This article covers the features and improvements we’ve added to debuginfod since our last update.

    [...]

    Debuginfod is a part of the elfutils project. Tools that already use elfutils to find or analyze debugging resources automatically inherit debuginfod support. Tools like Systemtap, Libabigail, and dwgrep all inherit debuginfod this way. In Systemtap, for example, debuginfod offers new ways to specify which processes to probe. Previously, if you wanted to explore a running user process, you would have to provide either a process identifier (PID) or the executable path. With debuginfod, Systemtap can probe processes according to build-id, as well. So, it is possible to investigate specific versions of a binary independently from the location of the corresponding executable file.

    Debuginfod includes a client library (libdebuginfod) that lets other tools easily query debuginfod servers for source files, executables, and of course, debuginfo—generally, DWARF (debugging with attributed record format) debuginfo. Since last year, a variety of developer tools have integrated debuginfod clients. As of version 2.34, Binutils includes debuginfod support for its components that use separate debuginfo (readelf and objdump). Starting in version 9.03, the Annobin project contains debuginfod support for fetching separate debuginfo files, and support for Dyninst is planned in version 10.3.

  • Fedora Community Blog: A sneak peek at Fedora Zine

    So my Outreachy internship is winding to a close, as is the creation of the first-ever edition of our very own Fedora Zine!

    It has been a crazy journey so far and I have thoroughly enjoyed working on this awesome project, especially getting to see and work with all of these great submissions from the community. I have learned so much; from how to balance my design visually, how to pair fonts and use other typographic effects, how to use guides for a perfectly aligned design and also that you should read your printing specs very, very carefully before getting to work on a project.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
