  • Looking for a new owner for my modules | Damien "dams" Krotkine [blogs.perl.org]

    I'm looking for someone to take over as maintainer of these distributions. Some of these distributions contain relatively important modules, like Redis and IO-Socket-Timeout.

  • Entering the Charts | lichtkind [blogs.perl.org]

    As part of HalleLeipzig.pm I had my duties to co-organize the recent German Perl Workshop but also the opportunity to give some talks. (Recordings are online soon at the CCC video platform). My main talk was about plotting data with Perl (english slides).

    I covered the data preparation phase and which Perl modules can handle the necessary math (Stats::Basic, Statistics::PCA, Statistics::KernelEstimation, Math::Spline and so on ). I also taught some color and design theory and how to use the proper visualization properties depending on importance and data type (and modules like Color::Library, Convert::Color, colorbrewer). The third part was a review of all the big and small plot libs on CPAN. And there was a lot to roast because especially the pure Perl ones are often half baked with lots of shortcomings, but also most of the big libraries (wrappers) had serious issues (may post for another day). This process led me also to investigate the module Chart, which was kinda feature complete, well documented, had some 90'ies charm, but also some minor technical issues like can't install from CPAN. So I took the adventure and overtook maintainership, wich went surprisingly smoothly.

  • Reconsidering the licensing of Perl code [Ed: GPL is not a "burden", this is about people trying to make Perl more proprietary-friendly]

    The current state: The Perl interpreter and most of CPAN are provided under the Artistic 1.0 license and the GPL1.0 license. The Artistic 1.0 license was written by Larry Wall and due to its problems Perl is simultaneously licensed under the GPL 1.0 License.

    It is the de-facto standard to license software published to CPAN under the same terms as the Perl interpreter.

    The Artistic 2.0 license supersedes the Artistic 1.0 license and is designed to overcome it's problems. Raku uses this license as it was specifically created for Perl 6. Mojolicious also uses this license.

    The Artistic licenses are not widely used outside the Perl & Raku sphere.

  • Memory Leak in Perl

    I always find the topic Memory Management very fascinating. Perl being the Perl, there is nothing you need to worry about. All memory management is done for us for FREE.

    Still, there was something, I always wanted to find out about memory management in Perl.

  • 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.
