  • Why Django Is The Popular Python Framework Among Web Developers?

    Nowadays, a lot of backend web development programs are developed and run with Python. Python has been one of the most popular programming languages for web development and its agility and versatility are strong reasons for its growing success. From developing simple codes to data analytics and machine learning, Python has become the go-to language for many developers.

    There are a lot of frameworks that work with Python and these frameworks basically allow the developers to choose a platform on which they can customize their website and test it freely according to their preferences. Among all the frameworks of Python, Django seems to be the most popular option. In fact, in the Stack Overflow Survey of 2018, Django was included as one of the most loved frameworks with 58% of the developers voting for it.

  • Not all OpenJDK 12 builds include Shenandoah: Here’s why

    A little history: Shenandoah, a high-performance low-pause-time garbage collector, is a Red Hat-led project. When we first proposed to contribute Shenandoah to OpenJDK, Oracle made it clear that they didn’t want to support it. That’s fair enough: OpenJDK is free software, so you don’t have to support anything you don’t want. We told Oracle that we’d work with them to design a really clean pluggable garbage-collector interface that allows anyone easily to select the garbage collectors to include in their builds. We did that together, and Shenandoah went in to JDK 12.

    Evidently Oracle has chosen not to build Shenandoah. They aren’t doing anything strictly wrong by excluding it, but something doesn’t feel right to me. These builds aren’t supported by Oracle—you need their commercial binaries to get support—so why exclude Shenandoah? It might simply be that they used their standard build scripts to build their open source binaries. However, in a rather feature-light OpenJDK release, I find it odd for open source builds to exclude one of the most significant contributions. I really appreciate Oracle providing GPL-licensed OpenJDK builds, but I wish they’d build all of it.

  • Announcing OpenJDK 11 packages in Ubuntu 18.04 LTS

    OpenJDK 11 is now the default Java package in Ubuntu 18.04 LTS, replacing OpenJDK 10, the previously supported rapid release version and original package default for Ubuntu 18.04. This OpenJDK package is covered by the standard, LTS upstream security support and will also be the default package for the upcoming Ubuntu 19.04 release.

    Version 11 is the latest Long Term Support (LTS) version of the open-source implementation of the Java Platform, Standard Edition (Java SE). It incorporates key security improvements, including an update to the latest Transport Layer Security (TLS) version, TLS 1.3, and the implementation of ChaCha20-Poly1305 cryptographic algorithms, a new stream cipher that can replace the less secure RC4.

  • Learn Ansible By Doing With These Courses And Hands-On Labs

    Infrastructure as code has changed the way that we plan, deploy, and maintain infrastructure. One of the technologies that made this transformation possible is Ansible. Ansible is a popular orchestration tool used by many individuals and small to large scale organizations, so knowing how to use it can provide a lot of opportunities.

    Even if you end up needing to learn other tools in the future such as Puppet, Chef, Salt, or Terraform (read: Ansible vs. Terraform), understanding Ansible and how it works will make it much easier to then learn how to use these other technologies. So don’t worry about the “which tool should I learn first?!” question. Just pick one, learn it, and you’ll be setup for the future.

  • 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.
