  • An introduction to the Julia language, part 2

    Part 1 of this series introduced the Julia project's goals and development process, along with the language syntax, including the basics of control flow, data types, and, in more detail, how to work with arrays. In this part, user-defined functions and the central concept of multiple dispatch are described. It will also survey Julia's module and package system, cover some syntax features, show how to make plots, and briefly dip into macros and distributed computing.

  • Learning about Go internals at GopherCon

    GopherCon is the major conference for the Go language, attended by 1600 dedicated "gophers", as the members of its community like to call themselves. Held for the last five years in Denver, it attracts programmers, open-source contributors, and technical managers from all over North America and the world. GopherCon's highly-technical program is an intense mix of Go internals and programming tutorials, a few of which we will explore in this article.

    Internals talks included one on the scheduler and one on memory allocation; programming talks included why not to base your authorization strategy on hash-based message authentication codes (HMACs). But first, here's a little about upcoming changes to Go itself.

  • How subroutine signatures work in Perl 6

    In the first article in this series comparing Perl 5 to Perl 6, we looked into some of the issues you might encounter when migrating code into Perl 6. In the second article, we examined how garbage collection works in Perl 6, and in the third article, we looked at how containers replaced references in Perl 6. Here in the fourth article, we will focus on (subroutine) signatures in Perl 6 and how they differ from those in Perl 5.

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.
