Programming: Masters and slaves, backing the wrong horse, and Julia

  • Redis does a Python, crushes 'offensive' master, slave code terms

    The open-source Redis database, like the Python programming language, is moving away from using the technical terms "master" and "slave" in its documentation and API – to the extent that's possible without breaking things.

    For Python, the decision this week to replace the words "master" and "slave", prompted by undisclosed complaints that they're offensive, led to a backlash.

    Meanwhile, those overseeing Python's CPython repo on Github today locked a pull request purging the words, and deleted several comments. But not before one developer highlighted the irony of executing the word change using the Git version-control software, which still relies heavily on "master" – for example, merging commits in the master branch. (Barely any instances of "slave" appear in Git code, though.)

    The Register asked Python developer Victor Stinner, author of the pull requests and Python bug report at the heart of the issue, whether he would like to discuss the controversy, but he declined. In previous comments, he justified his proposals to strip "master" and "slave" from the widely used programming language by saying some people object to the terms.

  • Backing the wrong horse?

    I started using the Ruby programming in around 2003 or 2004, but stopped at some point later, perhaps around 2008. At the time I was frustrated with the approach the Ruby community took for managing packages of Ruby software: Ruby Gems. They interact really badly with distribution packaging and made the jobs of organisations like Debian more difficult. This was around the time that Ruby on Rails was making a big splash for web application development (I think version 2.0 had just come out). I did fork out for the predominant Ruby on Rails book to try it out. Unfortunately the software was evolving so quickly that the very first examples in the book no longer worked with the latest versions of Rails. I wasn't doing a lot of web development that at the time anyway, so I put the book, Rails and Ruby itself on the shelf and moved on to looking at the Python programming language instead.

    Since then I've written lots of Python, both professionally and personally. Whenever it looked like a job was best solved with scripting, I'd pick up Python. I hadn't stopped to reflect on the experience much at all, beyond being glad I wasn't writing Perl any more (the first language I had any real traction with, 20 years ago).

  • Google's Dataset Search, Julia programming language, and more news

    TechRepublic described this programming language, originating from 2012 and just released as version 1.0, as follows: "designed to combine the speed of C with the usability of Python, the dynamism of Ruby, the mathematical prowess of MatLab, and the statistical chops of R."

    Liked by data scientists and mathematicians, Julia is also used in industries, such as the automotive industry for self-driving cars, and for 3-D printing.

    Julia is open source, counts 700 active contributors, 1,900 registered packages and two-million downloads. Details, download, and documentation can be found on julialang.org.

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.
