  • Report of June 16th Cubicweb Meeting

    Here is the weekly report of last week meeting with some delay...

  • Python 101 – Working with Files

    Application developers are always working with files. You create them whenever you write a new script or application. You write reports in Microsoft Word, you save emails or download books or music. Files are everywhere. Your web browser downloads lots of little files to make your browsing experience faster.

    When you write programs, you have to interact with pre-existing files or write out files yourself. Python provides a nice, built-in function called open() that can help you with these tasks.

  • PSF GSoC students blogs: Weekly Blog Post #2

    Hi every one, So after 3 weeks my PR finally got merged now tern have html feature up and running. I had some quizzes at the start of week so it was a very busy start of the week.

  • Rust for Data-Intensive Computation

    I have some thoughts on the use of Rust for data-intensive computations. Specifically, I’ve found several of Rust’s key idioms line up very well with the performance and correctness needs of data-intensive computing.

  • Diving into Rust with a CLI

    A blog post titled, "Diving into Go by Building a CLI Application" has been making it's rounds of the internet. It uses a small XKCD downloader as the subject. I thought was small and self contained enough, that it'd be interesting to see the same example in Rust!

  • Writing Non-Trivial Macros in Rust

    Macros in Rust tend to have a reputation for being complex and magical, the likes which only seasoned wizards like @dtolnay can hope to understand, let alone master.

    Rust’s declarative macros provide a mechanism for pattern matching on arbitrary syntax to generate valid Rust code at compile time. I use them all the time for simple search/replace style operations like generating tests that have a lot of boilerplate, or straightforward trait implementations for a large number of types.

  • This Week In Rust: This Week in Rust 344
  • Cross building Rust GStreamer plugins for the Raspberry Pi

    In our previous post we discussed about how Rust can be a great language for embedded programming. In this article, we'll explain an easy way to setup to cross build Rust code depending on system libraries, a common requirement when working on embedded systems.

  • A surprising way to do data science with Node.js

    JavaScript (also known as JS) is the lingua franca of the web, as it is supported by all the major web browsers—the other languages that run in browsers are transpiled (or translated) to JavaScript. Sometimes JS can be confusing, but I find it pleasant to use because I try to stick to the good parts. JavaScript was created to run in a browser, but it can also be used in other contexts, such as an embedded language or for server-side applications.

    In this tutorial, I will explain how to write a program that will run in Node.js, which is a runtime environment that can execute JavaScript applications. What I like the most about Node.js is its event-driven architecture for asynchronous programming. With this approach, functions (aka callbacks) can be attached to certain events; when the attached event occurs, the callback executes. This way, the developer does not have to write a main loop because the runtime takes care of that.

  • How to install the Strapi Node.js headless CMS

    Strapi is a cross between a content management system (CMS) and a Node.js framework. With this headless tool running in your data center, you'll save weeks of API development time. Strapi offers only the basic functionalities for managing content and users, while allowing you to manage and share that content via REST or GraphQL.

  • Character equivalence classes 2: the nature of equivalence

    In part 1 of this 2-part series I showed how to use POSIX equivalence classes in searching and replacing. But what does "equivalence" actually mean?

    It's complicated, but equivalence classes based on Unicode are derived mainly from the script in which the characters appear, not by the appearance of the characters.

  • Regarding Git and Branch Naming

    Existing versions of Git are capable of working with any branch name; there's nothing special about ‘master’ except that it has historically been the name used for the first branch when creating a new repository from scratch (with the git init command). Thus many projects use it to represent the primary line of development. We support and encourage projects to switch to branch names that are meaningful and inclusive, and we'll be adding features to Git to make it even easier to use a different default for new projects.

  • 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.
