  • Raspberry Pi: After launching five devices in less than a year, here's what they're doing next

    For Raspberry Pi, the passage of time over the past year has been marked by the launches of a series of new products (four devices in 2020, to be precise, plus another device in January this year), a feat the British computer maker managed to pull off despite the country being plunged into a series of COVID-19 lockdowns.

    Demand for its tiny computers soared due to the overnight switch to home working. On top of that, after the launch of Raspberry Pi's High Quality Camera in April 2020, the company went on to launch the 8GB Raspberry Pi 4 one month later. This would be followed by the Compute Module 4, the Raspberry Pi 400, and most recently, the $4 Raspberry Pi Pico in January this year.

    "We went into the pandemic with this enormous pipeline of stuff to do," Raspberry Pi creator and co-founder, Eben Upton, tells TechRepublic. "Every single one of those [launches] moves us forward quite a long way."

  • Banana Pi BPI-M2 Pro compact Amlogic S905X3 SBC launched for $61

    Banana Pi has already designed an Amlogic S905X3 SBC with Banana Pi BPI-M5 that closely follows Raspberry Pi 3 Model B form factor, but they’ve now launched a more compact model with Banana Pi BPI-M2 Pro that follow the design of the company’ earlier BPI-M2+ SBC powered by the good old Allwinner H3 processor.

  • Yet Another Rigol DS1054Z Viewer

    This is coded in Pascal (FPC Lazarus), but we weren’t able to browse the program because [Alfred] hasn’t posted the source code yet. It is written only for Linux, and he has tested it on Ubuntu, Debian, Fedora, and Manjaro. The project relies on Python, PyVisa, and gtk2, and talks to your DS1054Z over USB or LAN. The installation instructions are well documented, but as [Alfred] himself warns, if you encounter trouble arising from subtle dependency version conflicts, you may need to be a nerd and/or a pensioner with unlimited time on your hands to solve them. There is no users guide nor extensive help according to [Alfred]. However, simple hints might be found in hover text or by pressing F1. Disclaimers aside, this looks like an interesting project to try out.

    As [Alfred] notes, there are many other tools available to fetch data and images from your Rigol oscilloscope. [Jenny List] wrote a two-part series on using Python to control your test instruments, and here’s an example of a simple Python script that does a screen grab. Do you have a favorite way to remotely operate your oscilloscope? Let us know in the comments below.

  • 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.
