  • Symbolic mathematics on Linux

    This article is an introduction to the world of free and open-source applications for symbolic mathematics. These are programs that assist the researcher or student through their ability to manipulate mathematical expressions, rather than just make numerical calculations. I'll give an overview of two large computer algebra packages available for Linux, and a briefer sampling of some of the more specialized tools aimed at particular branches of mathematics.

    This category of software is traditionally called a "computer algebra system", but that description can be misleading. These systems can find analytic solutions to algebraic and differential equations; solve integrals; sum infinite series; and generally carry out nearly any kind of mathematical manipulation that can be imagined. At the least, symbolic mathematics software can replace the bulky handbooks of mathematical information that have been lugged by generations of graduate students.

    Over decades, mathematicians have honed these programs, encoding within them the accumulated mathematical knowledge of centuries: information about special functions, for example, that's so difficult (for some of us) to remember. They have learned to reduce such things as algebraic simplification and calculating derivatives to patterns of symbol manipulation ripe for automation. The earliest of these systems, developed in the 1960s, were based on Lisp, the obvious choice at the time, but development of later systems used a variety of languages.

    Fortunately, most of the best of this software is free and open source, which allows us to look under the hood and examine or alter the algorithms employed.

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.
