  • Get started with clang-tidy in Red Hat Enterprise Linux

    Clang-tidy is a standalone linter tool for checking C and C++ source code files. It provides an additional set of compiler warnings—called checks—that go above and beyond what is typically included in a C or C++ compiler. Clang-tidy comes with a large set of built-in checks and a framework for writing your own checks, as well.

    Clang-tidy uses the same front-end libraries as the Clang C language compiler. However, because it only takes source files as input, you can use clang-tidy for any C or C++ codebase no matter what compiler you are using.

  • Excellent Free Tutorials to Learn Elm

    Elm is a functional language that compiles to JavaScript. It helps you make websites and web apps. It has a strong emphasis on simplicity and quality tooling.

    Elm is purely functional, and is developed with emphasis on usability, performance, and robustness. It advertises “no runtime exceptions in practice,” made possible by the Elm compiler’s static type checking.

    Elm is open source, licensed under a Revised BSD license.

  • Elixir and Phoenix after two years

    Thoughts on the Elixir language and its Phoenix framework after two years of professional work.

    I am a seasoned web developer (working primarily with Ruby on Rails before) and someone who got an opportunity to work on a commercial Elixir project. During the past 2 years, I wrote a lot of Elixir, which I had to learn from scratch. I always found this kind of personal post interesting, so I figured I would write one for you.

  • Perl Weekly Challenge 107: Self-Descripting Numbers and List Methods

    These are some answers to the Week 107 of the Perl Weekly Challenge organized by Mohammad S. Anwar.

    Spoiler Alert: This weekly challenge deadline is due in a couple of days (April 11, 2021). This blog post offers some solutions to this challenge, please don’t read on if you intend to complete the challenge on your own.

  • Rakudo Weekly News: 2021.14 Floating Rats

    Steve Roe has published an interesting blog post about how the Raku Programming Language is holding up under the Muller Extreme Challenge, an algorithm designed to break computational accuracy: raku:34 python:19 extreme math. This in turn caused a discussion on /r/rakulang and in the end a Pull Request for a new feature!

  • A Tour of Safe Tracing GC Designs in Rust

    I’ve been thinking about garbage collection in Rust for a long time, ever since I started working on Servo’s JS layer. I’ve designed a GC library, worked on GC integration ideas for Rust itself, worked on Servo’s JS GC integration, and helped out with a couple other GC projects in Rust.

    As a result, I tend to get pulled into GC discussions fairly often. I enjoy talking about GCs – don’t get me wrong – but I often end up going over the same stuff. Being lazy I’d much prefer to be able to refer people to a single place where they can get up to speed on the general space of GC design, after which it’s possible to have more in depth discussions about the specific tradeoffs necessary.

    I’ll note that some of the GCs in this post are experiments or unmaintained. The goal of this post is to showcase these as examples of design, not necessarily general-purpose crates you may wish to use, though some of them are usable crates as well.

  • 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.
