  • John Goerzen: Distributed, Asynchronous Git Syncing with NNCP

    I have a directory that I use with org-mode and org-roam. I want it to be synced across multiple machines. I also want to keep the history with git. And, I want to use end-to-end encryption (no storing a plain git repo on a remote server), have a serverless setup, not require any two machines to be up simultaneously, and be resilient in the face of races and conflicts.

  • Making Taint support optional in Perl

    One of the changes to Perl that we're considering on p5p (the perl5-porters mailing list) is the removal of taint support. The first step towards that is to add a Configure option that lets you build a Perl without taint support.

    In this post I'll explain what we're considering, and why. The purpose of this post is to let everyone beyond p5p know about this, and give you a chance to comment.

  • A dream realized

    Have you heard that they are finally putting together a proposal to add a clean modern OO system into the core of Perl?

    If you haven’t, I strongly encourage you to look over the RFC for Corrina, or at least watch Ovid’s excellent presentation on the project.

    It’s reassuring that the list of contributors to the proposed design includes some of the most highly respected names in the Perl community, many of whom have previously taken one (or more!) tilts at this particular object-oriented windmill.

    Indeed, over the past two decades I too have repeatedly attempted to design and prototype richer and more robust OO systems for Perl, starting way back in the previous millennium with a brief stint as the maintainer of Class::Struct, and continuing on though the release of modules such as Class::Std, Class::Delegation, and most recently: Dios.

  • Python Iterators And Generators

    In this notebook, we would explore the difference between iterators and generators, how to use them and also the best use cases for each of them.

  • How to Graph in Python

    This article was contributed by Juni Learning, a learning platform for students ages 7-18 that offers 1:1 classes in computer science, math, and English. The article originally appeared on the Juni Learning website and is reposted here with permission.

    Hi, my name is Ritika and I’m a senior instructor at Juni Learning! Welcome to this basic Python data science tutorial.

    Today we’ll talk about how we can gather data and graph it in Python. Specifically, today we'll be working with survey data that we get beforehand from friends or family by asking what their favorite food is.

    We’ll learn how to create bar graphs specifically using dataframes and the Seaborn package.

  • Build a JAR file with fastjar and gjar | Opensource.com

    One of the many advantages of Java, in my experience, is its ability to deliver applications in a neat and tidy package (called a JAR, or Java archive.) JAR files make it easy for users to download and launch an application they want to try, easy to transfer that application from one computer to another (and Java is cross-platform, so sharing liberally can be encouraged), and easy to understand for new programmers to look inside a JAR to find out what makes a Java app run.

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.
