  • Perl Weekly Challenge: Week #079: Count Set Bits & Trapped Rain Water

    I really enjoyed this week task. I had lots of fun working with the Trapped Rain Water task.

    This week, I was too busy with my $work, so couldn’t do either Swift coding or live video session. However I promise, I will catch up next week.

  • Add sound to your Python game

    Pygame provides an easy way to integrate sounds into your Python video game. Pygame's mixer module can play one or more sounds on command, and by mixing those sounds together, you can have, for instance, background music playing at the same time you hear the sounds of your hero collecting loot or jumping over enemies.

    It is easy to integrate the mixer module into an existing game, so—rather than giving you code samples showing you exactly where to put them—this article explains the four steps required to get sound in your application.

  • PyDev of the Week: William Cox

    This week we welcome William Cox as our PyDev of the Week. William is a data scientist who has spoken at a few Python conferences. He maintains a blog where you can catch up on what’s new with him

    [...]

    When I was 12 my dad dropped “Teach Yourself Perl in 21 Days” on my desk and said, “you should learn this.” It took me much longer than 21 days, but I’m glad he did that. I dabbled in several languages (PHP, Java, C) but spent many years in graduate school honing my MATLAB skills, due to its powerful plotting and data analysis capabilities. My first job was at a military contractor and they all used MATLAB. This was the early 10’s and Python was really taking off as the language of scientific computing so I was able to convince my boss that it was something I should be learning – he was especially attracted to how much money they could save over thir massive MATLAB bills. I got my 2nd job with my impressive iPython Notebook skills! It was, however, till I started my 2nd job that I finally started learning what it means to write software with a team. It’s a lot different than dabbling on your own.

  • pkgKitten 0.2.0: Now with tinytest and new docs

    A new release 0.2.0 of pkgKitten just hit on CRAN today, or about eleven months after the previous release.

    This release brings support for tinytest by having pkgKitten::kitten() automagically call tinytest::puppy() if the latter package is installed (and the user did not opt out of calling it). So your newly created minimal package now also uses a wonderful yet tiny testing framework. We also added a new documentation site using the previously tweeted-about wrapper for Material for MkDocs I really dig. And last but not least we switched to BSPM-based Continued Integration (which I wrote about yesterday in R4 #30) and fixed one bug regarding the default NAMESPACE file.

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.
