  • Team OpenCensus or OpenTracing? It'll be neither and both now: Hello, OpenTelemetry

    Something odd happened at KubeCon 2019. Rather than snipe at each other from the safety of Twitter, two very similar open-source projects opted to pool their ideas into one: OpenTelemetry.

    The project is geared towards solving the problem of working out just what the heck is happening in today's microservices or container-based apps. Logging without incurring a chunky overhead both in terms of generating useful telemetry and actually collating the output.

    Distributed tracing is a bit more than fancy logging, as one commentator put it. Think more a transaction log over all the containers, services and components used in an application.

    Two projects emerged to deal with the challenge – OpenCensus from Google and OpenTracing, co-created by Ben Sigelman of Lightstep.

  • PHP 7.4 as Software Collection.

    Version 7.4.0-alpha1 will be soon released. It's now enter the stabilization phase for the developers, and the test phase for the users.

    RPM of this upcoming version of PHP 7.4, are available in remi repository for Fedora 29, 30 and Enterprise Linux 7, 8 (RHEL, CentOS, ...) in a fresh new Software Collection (php74) allowing its installation beside the system version.

    As I strongly believe in SCL potential to provide a simple way to allow installation of various versions simultaneously, and as I think it is useful to offer this feature to allow developers to test their applications, to allow sysadmin to prepare a migration or simply to use this version for some specific application, I decide to create this new SCL.

  • HEIC / HEIF images support

    The HEIF image format (High Efficiency Image File Format) is now widely used, especially since iOS 11, so it make sense to be able to process these images.

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.
