Red Hat and Fedora: HPC, Ansible and More Flock Reports

  • HPC workloads in containers: Comparison of container run-times

    Recently, I worked on an interesting project to evaluate different container run-times for high-performance computing (HPC) clusters. HPC clusters are what we once knew as supercomputers. Today, instead of giant mainframes, they are hundreds, thousands, or tens of thousands of massively parallel systems. Since performance is critical, virtualization with tools like virtual machines or Docker containers was not realistic. The overhead was too much compared to bare metal.

  • A project manager's guide to Ansible

    For project managers, it's important to know that deploying Ansible will improve the effectiveness of a company's IT. Employees will spend less time trying to troubleshoot their own configuration, deployment, and provisioning. Ansible is designed to be a straightforward, reliable way to automate a network's IT tasks.

    Further, development teams can use the Ansible Tower to track applications from development to production. Ansible Tower includes everything from role-based access to graphical inventory management and enables teams to remain on the same page even with complex tasks.

    Ansible has a number of fantastic use cases and provides substantial productivity gains for both internal teams and the IT infrastructure as a whole. It's free, easy to use, and robust. By automating IT with Ansible, project managers will find that their teams can work more effectively without the burden of having to manage their own IT—and that IT works more smoothly overall.

  • Flock to Fedora '19

    I had a wonderful opportunity to go to Fedora’s annual contributor summit, Flock to Fedora in Budapest, Hungary. This is me penning down my takeaway from a week full of learning!

    [...]

    Apart from the talks, the conference outshone when it came to meeting mind-blowing developers. I got to know the most about Fedora and Red Hat through those interactions and it was a really pleasant experience. It was also super amazing to finally meet all the people I had been interacting with over the course of the internship in real life.

    My advice for any future Flock attendee would be to always make time to talk to people at Flock. Even I have a hard time interacting but the people are extremely nice and you get to learn a lot through those small interactions and end up making friends for a life time.

    Definitely taking back a tonne of memories, loads of pictures, and plethora of learning from this one week of experience.

  • Paul W. Frields: Flock 2019 in Budapest, Hungary.

    Last week I attended the Flock 2019 conference in Budapest, like many Fedora community members. There was a good mix of paid and volunteer community members at the event. That was nice to see, because I often worry about the overall aging of the community.

    Many people I know in Fedora have been with the project a long time. Over time, people’s lives change. Their jobs, family, or other circumstances move them in different directions. Sometimes this means they have less time for volunteer work, and they might not be active in a community like Fedora. So being able to refresh my view of who’s around and interested in an event like Flock was helpful.

    Also, at last year’s Flock in Dresden, after the first night of the conference, something I ate got the better of me — or I might have picked up a norovirus. I was out of commission for most of the remaining time, confined to my room to ride out whatever was ailing my gut. (It wasn’t pretty.) So I was glad this year also to be perfectly well, and able to attend the whole event. That was despite trying this terrible, terrible libation called ArchieMite, provided by my buddy Dennis Gilmore...

    [...]

    I also attended several sessions on Modularity. One of them was Merlin Mathesius’ presentation on tools for building modules. Merlin is on my team at Red Hat and I happened to know he hadn’t done a lot of public speaking. But you wouldn’t have guessed from his talk! It was well organized and logically presented. He gave a nice overview of how maintainers can use the available tools to build modules for community use.

    The Modularity group also held a discussion to hear about friction points with modularity. Much of the feedback lined up well with other inputs the group has received. We could solve some with better documentation and awareness. In some cases the tools could benefit from ease of use enhancements. In others, people were unaware of the difficult design decisions or choices that had to be made to produce a workable system. Fortunately there are some fixes on the way for tooling like the replacement for the so-called “Ursa Major” in Fedora. It allows normal packages to build against capabilities provided by modules.

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.
