  • Say Goodbye to Both the iPod and Pixel Headphone Jack

    For more than 20 years, the typical image of personal music included an Apple iPod and wired headphones. But that picture has slowly been changing. Now you’re more likely to see a smartphone and wireless earbuds. Apple and Google closed the coffin on two items this week to permanently change that picture. Apple announced it is discontinuing the iPod, and Google announced its new Pixel 6A smartphone will not have a headphone jack.

  • Flutter development framework now stable across platforms • The Register

    Google's Flutter development framework finally achieved its cross-platform aspirations with a stable release of Linux and macOS support.

    Flutter 3.0, announced at Google's I/O developer conference, provides developers with a way to write apps for the six major consumer-facing platform targets using the Dart programming language. And that's not to mention embedded devices.

    "With Flutter 2.0, we shipped web support, and just recently we shipped support for Windows," said Tim Sneath, director of product and user experience for Flutter and Dart, in an interview with The Register.

    "And now with Flutter 3.0, we finally reached the point where we have completed that journey. We have all of the six major platforms – iOS, Android, web, Windows, macOS, Linux – all supported as stable parts of the Flutter framework."

    For macOS, that means Intel and Apple Silicon support, via Universal Binary builds, as well as Apple Silicon support in development. Thanks to Dart's support for Apple Silicon, compilation is faster.

  • 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.
