  • Shift4Me is an automatic bicycle shifter

    These days many of us are turning to bicycling for fun and exercise. While some may enjoy being able to change up the resistance and pedal speed by shifting, if you would instead prefer to be in the ideal gear automatically, then Jan Oelbrandt’s Shift4Me could be just the thing you need.

    The add-on device works by determining the rider’s cadence via a magnetic sensor attached next to one of the pedals. If it’s significantly slower than a set range — 60 RPM in the video below — it shifts down to decrease resistance. If higher, it upshifts.

  • Linux-driven i.MX6ULL IoT gateway offers mini-PCIe and CANBus too

    Artila’s DIN-rail mountable “Matrix-752” IoT gateway runs Linux on an i.MX6 ULL with 16GB eMMC, 2x LAN, 2x serial, USB OTG, isolated CAN and DIO, and mini-PCIe with micro-SIM.

    Artila Electronics has launched a variation on the Matrix-750 introduced earlier this year. Like that model, the Matrix-752 runs Linux 4.19x on NXP’s 800MHz, Cortex-A7 based i.MX6 ULL, which is faster than the 536MHz, Cortex-A5 Microchip ATSAMA5D35 that powers many of Artila’s gateways such as the similar Matrix-710 and Matrix-713.

  • IBASE Outs Fanless Embedded Systems with AMD Ryzen V1605B, V1202B, R1606G, or R1505G SoC

    The company lists Windows 10, Windows 10 IoT Enterprise, Windows Embedded Standard 8, and Ubuntu 16.04 as supported operating systems.

  • USBImager – A Lightweight Alternative to balenaEtcher

    The common way to flash OS images to SD cards used to be “dd”. But you could potentially damage your system with a wrong command, it will not do verification after writing the firmware image, and it was not available in Windows, so people had to use Win32DiskImager, and last time I check it did not do verification either.

    So Etcher, now called balenaEtcher, became a popular cross-operating systems tool to flash images for Raspberry Pi and other SBCs. It’s easy to use and does verification after flashing. However, the binary is rather large at around 130 MB, and the company started to show sponsors to fund the development of the program, and this was not to the liking of everyone.

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.
