  • Rocky Linux release candidate is now available and is exactly what CentOS admins are looking for

    If I didn't know the new Rocky Linux ISO image was a release candidate (RC), I'd have thought it to be a final release. It's not, and the developer wants to make sure everyone is aware this first unleashing is not ready for production environments. For all the warnings, the Rocky Linux RC is remarkably stable and gives us a clear view of what's to come from the original creator of CentOS.


    The Rocky Linux RC1 release is available for x86_64 and AArch64 architecture and can be downloaded as a minimal, boot and full installation. Kurtzer opted to go with the same installer as CentOS, RHEL and AlmaLinux (Anaconda), so installation will be instantly familiar to anyone who's installed any of the aforementioned Linux distributions.

  • May the Fourth be with you via Podman

    Happy May Fourth, everyone! A few weeks after Star Wars first released, I was lucky enough to see it in a Dolby theatre in Denver, CO. I was hooked, completely, and totally hooked. Over the past decade or so, I’ve built a really nice large screen television with surround sound setup and rarely go to the movies anymore. I wait for them to be streamed or hit Blue-Ray. I make an exception for Star Wars movies. Those I go see at least once at a theatre. Then yes, I buy a copy to watch at home when available.


    So after a colleague said I should run it from a container, I thought I’d try doing so. I made a few attempts at getting it to run but ran into issues with Telnet both in the container and on my host. Google to the rescue. I discovered the ascii-telnet-server project.

  • Rocky Linux, AlmaLinux, CentOS & syslog-ng

    Last year, the CentOS project announced a major shift in strategy. Until recently, CentOS Linux has been a rebuild of Red Hat Enterprise Linux (RHEL) sources, each RHEL release was quickly followed by a corresponding CentOS Linux release. While CentOS 7 keeps working this way, CentOS 8 will reach its end of life by the end of this year. The CentOS project is focusing on CentOS Stream. It is a continuous stream of bug fixes and new features.

    Some of the users were not happy about the change, that is how Rocky Linux and AlmaLinux were born.

    As about 80% of syslog-ng Open Source Edition (OSE) installations run on CentOS and RHEL (if we do not count Kindle devices…), support for CentOS Stream and CentOS Linux alternatives is a returning question. From this blog, you can learn about CentOS Stream and CentOS Linux alternatives and how the situation is affecting syslog-ng OSE users.

  • Compliance clarity with Red Hat Insights

    Compliance and security management are interdependent. Compliance depends on security rules for enforcement. Security depends on clear compliance guidelines. Any lack of visibility to the enforcement of security policies as related to specific regulations can expose an organization to risk. With increased regulation, new business processes due to COVID, and reduced budgets, CIOs, compliance officers, system administrators and legal teams are seeking ways to work together to reduce risk.

    Organizations routinely conduct audits to identify gaps as regulations increase, but audits are not the best way to discover issues. Audits create stress for all. Red Hat Insights for Red Hat Enterprise Linux (RHEL) simplifies the management of compliance and security. Insights helps organizations address compliance in a systematic fashion and reduce operational costs. Insights can help enforce a variety of cybersecurity policies, (including PCI-DSS, HIPAA, CIS, etc.) that your organization needs to meet.

  • Event-driven APIs and schema governance for Apache Kafka: Get ready for Kafka Summit Europe 2021

    As a developer, I’m always excited to attend the Kafka Summit, happening this year from May 11 to 12. There are so many great sessions addressing critical challenges in the Apache Kafka ecosystem. One example is how changes to event-driven APIs are leading developers to focus on contract-first development for Kafka.

    In preparation for the upcoming Kafka Summit, this article discusses the journey Kafka users have taken to get on the API bandwagon and how developers are using contracts to describe brokers without losing control of their data in the cluster. A critical component for effective schema governance is having a schema registry such as Apicurio Registry. See the end of the article for information about Red Hat’s sessions during the Kafka Summit Europe 2021.


    Implementing an event-driven architecture using Apache Kafka alongside the traditional API approach has brought new challenges and expectations. The conventional code-first workflow (of implementing the code first and then sharing the resulting API specification) includes many bottlenecks that prevent efficient progress. Developers are seeking a new direction for discoverability and access to event-stream endpoints.

  • Red Hat Announces The Open Source StackRox Community

  • Custom policies in Red Hat 3scale API Management, Part 2: Securing the API with rate limit policies

    In Part 1 of this series, we discussed the policy framework in Red Hat 3scale API Management—adding policies to the APIcast gateway to customize API request and response behavior. In this article, we will look at adding rate limiting, backend URL protection, and edge limiting policies to the APIcast gateway. We’ll also review which policies are appropriate to use for different use cases.

  • IT job hunt: 3 tips to get a recruiter's attention

    There’s a skill shortage for tech talent. If you’re a developer or data scientist, you might think that puts you in the driver’s seat for most jobs. While supply and demand play a role, for top IT roles it’s still essential to stand out early in the process. Here are three ways to do that.

  • 4 Artificial Intelligence (AI) skills IT pros must have

    Artificial Intelligence (AI) has arguably become a household term in modern enterprises. By now, most companies have embraced some type of business initiative that includes AI in their digital transformation.

    Artificial Intelligence is a broad term, but much current research and development focuses on machine learning (ML), a subdiscipline whereby machines learn from data as opposed to being explicitly programmed.


    The essential question is whether such data has the potential to solve the business problem at hand. While the answer is not always immediately obvious, it begins with a hypothesis stemming from prior analysis or perhaps simply based on intuition. For example, a business experiencing high customer churn might hypothesize that recent changes in commercial activity could predict future attrition.

  • Optimizing the Clang compiler’s line-to-offset mapping

    Recently, I’ve been trying to improve the speed of the Clang compiler for C and C++. When I profile the Clang pre-processing step on a large file, one function quickly stands out:

    clang::LineOffsetMapping::get(llvm::MemoryBufferRef Buffer, llvm::BumpPtrAllocator &Alloc)
    This function basically allocates a vector (through Alloc) that maps line numbers to offsets in a file (loaded in Buffer). That’s a surprisingly standalone function, so it’s easy to extract it in a micro-benchmark and go for an optimization journey. This article is a kind of log book of that trip.

  • 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.
