  • 10 Years’ Perspective on Python in Gentoo

    I’m a Gentoo developer for over 10 years already. I’ve been doing a lot of different things throughout that period. However, Python was pretty much always somewhere within my area of interest. I don’t really recall how it all started. Maybe it had something to do with Portage being written in Python. Maybe it was the natural next step after programming in Perl.

    I feel like the upcoming switch to Python 3.9 is the last step in the prolonged effort of catching up with Python. Over the last years, we’ve been working real hard to move Python support forward, to bump neglected packages, to enable testing where tests are available, to test packages on new targets and unmask new targets as soon as possible. We have improved the processes a lot. Back when we were switching to Python 3.4, it took almost a year from the first false start attempt to the actual change. We started using Python 3.5 by default after upstream dropped bugfix support for it. In a month from now, we are going to start using Python 3.9 even before 3.10 final is released.

    I think this is a great opportunity to look back and see what changed in the Gentoo Python ecosystem, in the last 10 years.

  • Perl Monthly Report - April

    I had many ups and downs in the month of April. In all these, I have recieved plenty of supporting voices.

  • Paws anyone?

    Gee almost a year since my lat post. I better start posting again or Mohammad will catch up with me Wink.

    Been quite a year for every one on this big blue marble. I hope you are all good.

    Ok here is the very short post for today.

  • Config::BINDish Module First Release - LFlat, The Home of Vrurg

    Soon after Test::Async time has came for the first release of Config::BINDish. At first, I didn’t plan the module whatsoever. Then I considered it as a little distraction project to get some rest from an in-house one I was working on lately. But it turned into a kind of a monster which swallowed quite an amount of my time. Now I hope it’s been worth the efforts.

    Basically, the last straw which convinced me to eventually put everything else aside and have this one done was an attempt to develop a model for scalable file hosting. I was stuck, no approach I was considering was good enough. And I decided to change the point of view and try to express the thing in terms of a configuration file. I went on a hunt onto Raku modules site and came back with a couple of already familiar options. Of those I decided that Config::TOML would be the best one for my needs. Unfortunately, very soon I realized that a feature it misses makes my life somewhat harder than I’d like it to be: there was no way to expand a string with an option value.

  • RStudio and APIs

    Data Scientists and analysts work to constantly deliver valuable insights from data. In many cases, these individuals practice a Code First approach, using a programming language like R or Python to explore and understand data. Once an analysis reaches conclusion, it is important to carefully consider what happens next. Perhaps the analysis resulted in a complex machine learning model that can generate valuable predictions on new data. Or perhaps it resulted in some new business logic that can be implemented to improve efficiency. In any case, ensuring the longevity of analysis outcomes increases business value long after the original analysis concludes.

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.
