  • An awesome experience!

    GUADEC has been a week full of memorable moments. As my friend Rares mentioned in his post, our newcomers group was welcomed by friendly community members right as we arrived at the hotel. For someone who has never attended a similar event before, this really helped with getting into the conference atmosphere.

    In the first couple days of the conference, I found myself meeting a lot of people that I knew from IRC. It felt really nice to finally know the person behind the internet nick. I was especially excited about getting to meet my mentor, Carlos Soriano =). In between the presentations I also took the time to prepare my own lightning talk about compressed files in Nautilus. Speaking in front of the GNOME community for the first time was a unique experience.

  • Commvault Announces Support of Red Hat Virtualization 4 with Commvault Software
  • Modularity Infrastructure Design

    The purpose of our Modularity initiative is to support the building, maintaining, and shipping of modular things. So, in order to ensure these three requirements are met, we need to design a framework for building and composing the distribution.

    In terms of the framework, in general, we are concerned about the possibility of creating an exponential number of component combinations with independent lifecycles. That is, when the number of component combinations becomes too large, we will not be able to manage them. So that we don’t accidentally make our lives worse, we must limit the number of supported modules with a policy and provide infrastructure automation to reduce the amount of manual work required.

  • more, less, and a story of typical Unix fossilization

    In the beginning, by which we mean V7, Unix didn't have a pager at all. That was okay; Unix wasn't very visual in those days, partly because it was still sort of the era of the hard copy terminal. Then along came Berkeley and BSD. People at Berkeley were into CRT terminals, and so BSD Unix gave us things like vi and the first pager program, more (which showed up quite early, in 3BSD, although this isn't as early as vi, which appears in 2BSD). Calling a pager more is a little bit odd but it's a Unix type of name and from the beginning more prompted you with '--More--' at the bottom of the screen.

    All of the Unix vendors that based their work on BSD Unix (like Sun and DEC) naturally shipped versions of more along with the rest of the BSD programs, and so more spread around the BSD side of things. However, more was by no means the best pager ever; as you might expect, it was actually a bit primitive and lacking in features. So fairly early on Mark Nudelman wrote a pager with somewhat more features and it wound up being called less as somewhat of a joke. When less was distributed via Usenet's net.sources in 1985 it became immediately popular, as everyone could see that it was clearly nicer than more, and pretty soon it was reasonably ubiquitous on Unix machines (or at least ones that had some degree of access to stuff from Usenet). In 4.3 BSD, more itself picked up the 'page backwards' feature that had motived Mark Nudelman to write less, cf the 4.3BSD manpage, but this wasn't the only attraction of less. And this is where we get into Unix fossilization.

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.
