  • Customize your Raspberry Pi operating system for everyday use

    If you have a Raspberry Pi running Raspberry Pi OS (previously known as Raspbian) operating system, you know it's an awesome little computer with a great operating system for beginners that includes just about everything you could possibly want. However, once you become familiar with the Pi and want to start using it for other things, you might want an operating system (OS) that doesn't include everything in the default build.

    When that happens, you have two choices: You can pull your hair out trying to uninstall all the cruft you don't want, or you can use Raspberry Pi OS Lite to build your own custom, lightweight operating system tailored to your exact specs. I suggest saving yourself some time and aggravation and going with the latter option.

  • New product Monday: pi3hat

    This board breaks out 4x 5Mbps CAN-FD ports, 1 low speed CAN port, a 1kHz IMU and a port for a nrf24l01. Despite its name, it works just fine with the Rasbperry Pi 4 in addition to the 3b+ I have tested with mostly to date. I also have a new user-space library for interfacing with it that I will document in some upcoming posts. That library makes it pretty easy to use in a variety of applications.

  • Trace Together Token: Teardown and Design Overview

    On 19 June, GovTech Singapore invited four members of the community to come and inspect their new TraceTogether Token. This token removes the need to carry a phone at all times, and is designed to help both those who do not have a smart device capable of running TraceTogether well, including those using older Android devices, non-smartphones, and iOS users. I was among the group, which also consisted of Roland Turner, Harish Pillay, and Andrew "bunnie" Huang, who were given the opportunity to see the first public revision of hardware. In this post I will discuss the goal of the token, give some overview of the hardware, compare it with the app version of TraceTogether, and comment on the protocol changes.

  • 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.
