  • The x86 Platform Drivers For Linux 5.12 Have Several Prominent Additions - Phoronix

    The "platform-drivers-x86" area of the kernel that is primarily made up of driver support around Intel/AMD laptops and other platform drivers is seeing a number of noteworthy additions for the newly-opened Linux 5.12 merge window.

  • OProfile Kernel Code Slated For Removal In Linux 5.12 - Phoronix

    OProfile as a system profiler for Linux systems was started twenty years ago during the Linux 2.4 kernel days. While the user-space components are still going strong, the kernel-side support is redundant in an era of the perf subsystem and thus slated for removal with Linux 5.12.

    The OProfile user-space tools remain used and are still maintained (OProfile 1.4 came out last summer), but the kernel-side OProfile code is no longer needed since the user-space code has been refactored to make use of the Linux kernel's wonderful perf capabilities. Thus the kernel OProfile code has basically gone unused for quite a while unless running very vintage OProfile user-space tools.

  • Review of Five popular Hyperledger DLTs- Fabric, Besu, Sawtooth, Iroha and Indy

    As companies are catching up in adopting blockchain technology, the choice of a private blockchain platform becomes very vital. Hyperledger, whose open source projects support/power more enterprise blockchain use cases than others, is currently leading the race of private Distributed Ledger Technology (DLT) implementation. Working from the assumption that you know how blockchain works and what is the design philosophy behind Hyperledger’s ecosystem, in this article we will briefly review five active Hyperledger DLTs. In addition to DLTs discussed in this article, Hyperledger ecosystem has more supporting tools and libraries that I will cover in more detail in my future articles.

    This article mainly targets those who are relatively new to Hyperledger. This article would be a great resource for those interested in providing blockchain solution architect services and doing blockchain enterprise consulting and development. The materials included in this article will help you understand Hyperledger DLTs as a whole and use its high-level overview as a guideline for making the best of each Hyperledger project.

  • 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.
