  • Dirk Eddelbuettel: RcppArmadillo 0.10.7.0.0 on CRAN: New Upstream

    Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 912 other packages on CRAN.

    This new release brings us Armadillo 10.7.0 released this morning by Conrad. Leading up to this were three runs of reverse dependencies the first of which uncovered the need for a small PR for subview_cols support which Conrad kindly supplied.

  • PoCL 1.8 OpenCL Implementation Coming With LLVM 13 Support, Better SPIR-V On CUDA

    PoCL is the open-source project implementing OpenCL for CPU-based execution as well as multi-device support by getting its Portable Computing Language implementation working atop NVIDIA GPUs via CUDA, AMD GPUs via HSA, and other experimental implementations through leveraging LLVM/Clang.

  • Arm Begins Adding Armv9 Support To The GNU Compiler Toolchain

    Arm engineers have begun landing their Armv9 enablement work in the GNU compiler toolchain.

    Yesterday brought the initial Armv9 commits to GNU Binutils. This included adding armv9-a to -march for the GNU Assembler as well as for GAS adding the Cortex-X2, Cotex-A510, and Cortex-A710.

  • Awesome Python Video Tutorials Keep You Motivated | Hackaday

    Programming languages are one of those topics that we geeks have some very strong and often rather polarised opinions about. As new concepts in computing are dreamt up, older languages may grow new features, if viable, or get left behind when new upstarts come along and shake things up a bit. This scribe can remember his early days programming embedded systems, and the arguments that ensued when someone came along with a project that required embedded C++ or worse, Java, when we were mostly diehard C programmers. Fast forward a decade or two, and things are way more complicated. So much choice, so much opinion.

  • 8 reasons why I learned Core Java | Opensource.com

    Computer programming, also known as coding for short, is not about which language you use. It's about developing programming logic and learning to think like a programmer. The language you start with should be the one that helps you the most in this endeavor. So you have to ask yourself the question: "What do you want to do as a programmer?"

    For example, if you want to work on Android app development, video game development, desktop GUI applications, or just general software development, I think learning Java is an excellent option. It's the language I chose, and it has made a whole world of programming available to me. In India, where I live, the average salary of a Java programmer is around 5.9 Lakhs per Annum (LPA) (it can be as high as 10 LPA, depending on your experience.)

    Java is a vast language, though, with lots of frameworks and variants to choose from. Core Java is the term the tech industry has developed to refer to the central components of the Java language—the thing that people use to write the frameworks and has developed the cottage industry around Java. I believe that Core Java is one of the most powerful skills you can acquire because understanding the basics of Java gives you a significant advantage when learning all of the related tools built on top of it.

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.
