  • Is Freedom Phone the Trump University of Mobile Devices?

    Forget about building a better mousetrap. Wave a big enough U.S. flag, yell “freedom” loud enough, and the MAGA crowd will beat a path to your door.

    That’s the theory, anyway.

  • REVIEW: Tiny 2040

    To achieve a smaller footprint, a few compromises have been made. Most notably, the Tiny 2040 only has a total of 16 pins versus Pico’s 40, plus a debug header. Of these, there are 12 GPIO pins, compared to 26 on Pico. So it won’t be compatible with most Pico add-on modules. As with Pico, there’s no wireless connectivity.

    On the plus side, the Tiny 2040 does break out a fourth ADC input – which is connected to an on-board temperature sensor on Pico.

  • Raspberry Pi Wacky Inflatable Tube Guys Keep Students in Line

    As exciting as this Pi-powered dance party is, the project serves an even greater purpose in the world of education. Thecaptnjim is a high school graphics teacher and wanted to find a way to stop students from logging out of their machines before class is over. So instead of using something simple like an alarm clock or notification prompt, Thecaptnjim opted for a more entertaining solution.

    The idea was to create a visual-based warning system accompanied by sound. The result is a timer that plays a “hurry up” soundbite from one of the Super Mario Brothers games, followed up 30 seconds later with the activation of a pair of wacky waving inflatable tube men that dance to a random song—signaling to the students that class is over. After that, it’s okay to start packing up.

  • 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.
