  • Carson Black (jan Pontaoski): Go and Parsing

    Go is one of the best languages to write a parser and tools that need some form of parsing in.

    [...]

    Participle is a Go library that makes writing and parsing data into ASTs extremely easy. I'll demonstrate a simple usage of it for authoring a better Wayland protocol syntax that can transpile to XML.

  • Seaborn Line Plots: A Detailed Guide with Examples (Multiple Lines)

    In this Python data visualization tutorial, we will learn how to create line plots with Seaborn. First, we’ll start with the simplest example (with one line) and then we’ll look at how to change the look of the graphs, and how to plot multiple lines, among other things.

  • Core Workflow updates - Python Language Summit 202

    The PyCon 2015 sprint was the first time this blogger contributed to Python—or rather, I tried to. The three patches I submitted that year are awaiting a review to this day. In recent years, however, the core team has made bold changes to their development workflow to make their tasks easier, to spread responsibility more widely, and to improve the experience of contributors. When I submitted a patch in the 2018 sprints it was reviewed and merged in a few weeks. Mariatta Wijaya has led many of these changes. She presented the latest updates to the core workflow.

  • Sharing our research and licenses for going online with Python events

    In March 2020, we had to make a tough decision on whether to cancel EuroPython 2020 or run it online. Since we did not want to lose continuity and all the work we had already put into the in-person event, we decided to go for an online version.

    Now, just as many other in-person events, running the online version required a lot of research, experimentation, gaining knowledge in using online conference tools and finding a concept which would allow us to carry over as much of the in-person conference experience to the online version as possible.

  • The Rust Programming Language Blog: Announcing Rust 1.43.1

  • 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.
