  • Emacs for Python

    Python is all the rage for data scientists and web developers alike but how do you start? The best way to learn to program is to try out functions and ideas yourself. With Python, you have a great tool available by default: the interpreter. You can actually use it as a shell for everyday tasks. In the interpreter you can try the mathematics, create your ‘Hello World!’ and even define some functions. This is an excellent way to create a specific function before you start using your editor or IDE. If you want the full REPL, use Ipython or even better a Jupyter notebook. In a Jupyter Notebook, you can mix code with comment sections and even the results from your code. There are many examples of this online.
    When you are ready to start a full project, you have a few things to consider. First, you need to know what software you need. For each project, you will probably use different libraries and levels. In Python, this has been a special point of attention after the 3.x series was introduced. Some functions from 2.x are not supported by 3.x, because of this situation virtual environments was invented. Virtual environments are useful for making sure you use the particular libraries you expect and nothing else.

    When you choose IDE, or editor, you want to support these virtual environments to make your work simpler. You also need to have an easy way to test your latest patches. Other things you want at your fingertips are documentation, code completion and a testing environment.

    In Emacs, you have support for Python code highlighting from a vanilla install. When you want more, there are packages available for these functions and a few more. The philosophy of Emacs is that you will not need to leave the editor to keep doing your work. To achieve this, there are shells, a REPL and even support to have your Jupyter notebook inside the editor. You can also start a web server and use your browser to see what your latest code has done for your web page.

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.
