  • AMD Zen 3 Scheduler Model Finally Added To LLVM/Clang - Phoronix

    While last minute AMD Zen 3 "znver3" improvements managed to make it for GCC 11 that was recently released, the recent debut of LLVM 12.0 wasn't so lucky on the Zen 3 support front. There was the very basic enablement that landed in LLVM 12 but now the more complete support isn't expected until LLVM 13 this autumn.

    The initial "-march=znver3" support made it into LLVM 12 but the Zen 3 tuned scheduler model hadn't landed even though the initial scheduler model updates were posted for review in January. It was only this weekend that the Zen 3 scheduler model has now landed within LLVM Git for LLVM 13.0 that will debut as stable in September~October or slightly before that if making a LLVM 12.0.1 release with it back-ported.

  • New features in OpenMP 5.0 and 5.1

  • DevOps vs Software Engineer: What's the Difference?

    Software Engineers rule the IT planet. But during this era of DevOps, DevOps Engineers have also quickly emerged as the backbone of the IT industry.

    Some of these DevOps Engineers are here in the industry with a fresh start while others have evolved from being Software Engineers themselves.

    The roles and responsibilities of DevOps and Software Development overlaps in many areas, so it is easier to get confused between the two.

    I'll explain the difference between DevOps and Software Engineer. Before you look into these roles with an industrial point of view, it is essential to learn these areas of expertise individually.

  • Learn the Lisp programming language in 2021

    People who love thinking about the design of programming languages often love Lisp because of how its syntax and data share the same structure: Lisp code is essentially a list of lists, and its name is an acronym for LISt Processing. People who love thinking about the aesthetics of programming languages often hate Lisp because of its frequent use of parentheses for scoping; in fact, it's a common joke that Lisp stands for Lots of Irritating Superfluous Parentheses.

    Whether you love or hate its design philosophies, Lisp is an interesting glimpse at the past and, thanks to Clojure and Guile, into the future. You might be surprised how much Lisp code there is lurking within big codebases in any given industry, so it's a good idea to have at least a passing familiarity with the language.

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.
