  • Quick Rust Comparison

    I've been wanting to try out Rust with something very simple as a first pass through the language.

    [...]

    I decided to write a simple unoptimized version of the fibonacci sequence. My goal was to take enough time to be noticable...

  • Test and Code: 110: Testing Django - from unittest to pytest - Adam Parkin

    Django supports testing out of the box with some cool extensions to unittest. However, many people are using pytest for their Django testing, mostly using the pytest-django plugin.

    Adam Parkin, who is known online as CodependentCodr, joins us to talk about migrating an existing Django project from unittest to pytest. Adam tells us just how easy this is.

  • Object-Oriented Programming (OOP) concepts in Python

    In this article I will review the main concepts a beginner Python programmer should learn about OOP in Python. The content is explored in detail in other posts on the blog that are linked at the end of each section.

  • PWC 057: Task #1, Invert Tree & Task #2, Shortest Unique Prefix

    The flipping part is pretty easy, but since I'm a huge fan of Higher Order Perl I thought I should at least try to make it sort of like the tree walking code I remembered reading, where you give the tree-walker the function you want to operate on each node. (That word, "remembered" should be a hint that I haven't read the book in years and you should really go read the master.) I wrote both a depth-first and a breadth-first binary tree walker. For the purposes of flipping the whole tree, either one would have sufficed, but it is handy to have the option when you are experimenting.

    The second (and optional) part of the problem was pretty-printing the binary tree. I think the restriction of the input binary tree to be a full one was for the benefit of the fools attempting the bonus, but me being a fool, I ignored the helpful restriction and tried writing a generic binary tree pretty-printer. I wound up with a binary tree pretty-ish-printer.

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.
