  • The Baldcorder is James Lewis’ tricorder-like device for measuring light levels and temperature

    As part of element14’s Build Inside the Box Challenge, James Lewis (AKA Bald Engineer) decided to make his own DIY tricoder from Star Trek. In the series, a tricoder is a ubiquitous scanning tool that can perform various scans of the environment through its onboard sensors, as well as record and analyze them later — all in a handheld format. Lewis’ design incorporates a MKR Zero as the microcontroller, a phototransistor to detect light levels, and an analog temperature sensor to sense ambient temperatures.

    The enclosure itself was based on a tricorder toy and recreated in Fusion 360. It features a hinge mechanism for easy opening and closing, as well as handling the wiring harness that connects both halves of the device. Once it was 3D-printed, Lewis moved onto the electronics.

  • Power Your Raspberry Pi With These Low-Cost Battery Add-ons

    PiSugar Kitchen has released two new low-cost battery add-ons, the PiSugar S and PiSugar S Pro, that promise to power a Raspberry Pi for several hours on a charge.

  • Ethernet was slower only in one direction on one device

    A few months ago, when I was testing 10 Gigabit networking on the Raspberry Pi, I noticed something funny when I was doing iperf3 speed tests between devices connected through my MikroTik CRS305 10G switch.

  • 25 Gigabit Linux internet router PC build

    An alternative to many specialized devices, including routers, is to use a PC with an expansion card. An internet router’s job is to configure a network connection and forward network packets. So, in our case, we’ll build a PC and install some network expansion cards!

  • Apple co-founder Steve Wozniak: 'It's time to recognize the right to repair'

    Wozniak, who co-founded Apple 45 years ago with Steve Jobs, said that enabling others to retool their devices also has commercial value. He pointed to the success of the Apple II computer, which he said was "modifiable and extendable to the maximum" and the "only source" of profit for Apple during its first years.

    "It was not ... successful on pure luck," he added. "There were a lot of good things about that being so open that everyone could join the party."

  • President Joe Biden’s latest executive order is a huge win for right to repair

    The order is a significant win for the right to repair advocates who have long championed a consumer’s choice to have their technology fixed either by third parties or on their own, rather than solely by the manufacturer. Right to repair argues that anyone should have access to the OEM parts, manuals, and software needed to perform those repairs. Major gadget makers have lobbied to prevent this kind of repair accessibility, but the right to repair movement has been picking up momentum in recent years.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
