  • Listen to Larry Wall's State of the Onion 2000 on YouTube

    It’s a typical Larry talk filled with quirky, humorous observations about life and programming, and notably he announces the Perl 6 project.

    Unfortunately the audio is low quality (hey it was 20 years ago at a low-budget conference); you can read a transcript of the talk here (with mp3 download links at the bottom). We also have collection of attendees’ reports from the conference.

  • Chicago.pm Virtual Meeting: July 23

    In case you are not familiar with gather.town, after you join the conversation, you will have a small avatar on a 2d map and can walk around. When you are close to somebody or a group of people, you can video chat with them over video. Perlmongers is supposed to be a social gathering, and we are experimenting with this venue to see if it'll make that possible!

  • The Magit Git Client Is The "Killer Feature" In Emacs

    Users of other text editors often ask "why should I switch to Emacs?" or, more specifically, "what is the killer feature that Emacs offers?" Depending on your workflow, the killer feature for Emacs could be a number of things, one them being Magit!

  • Alder Lake-S Compiler Update Points to big.LITTLE Desktop Chips

    This design builds upon the big.LITTLE (Big.BIGGER in Intel parlance) design that debuted in the company's 3D Lakefield chips. These designs incorporate one large Sunny Cove core combined with four Atom Tremont smaller cores in an ARM-like design. With the architecture proven and already working its way through the ecosystem, it's rational to expect Intel to scale it up to tackle desktop PCs, too.

    The GNU compiler updates include a list of compatible instructions for both Intel's upcoming data center Sapphire Ridge chips and Alder Lake desktop chips, with the latter noticeably missing support for AVX-512, a SIMD instruction that Intel recently introduced to its desktop chips. These instructions are disabled in Intel's hybrid Lakefield chips to keep the instruction set consistent between cores (Atom doesn't support AVX instructions), therefore easing operating system scheduling routines that target different workloads at the cores best suited for the task. Therefore, the lack of AVX-512 support for Alder Lake could serve as further evidence that Intel will bring its hybrid architecture to desktop PCs.

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.
