  • Pico-ITX board spins triple 4K displays with Elkhart Lake

    Congatec announced a Linux-ready “Conga-PA7” Pico-ITX SBC with Intel’s new Atom x6000E SoCs with up to 16GB LPDDR4-4267 and 512GB UFS 2.0 flash, triple 4K display support, 2x GbE with TSN and OOB, and 2x USB 3.1.

    Congatec has announced an SBC and four SMARC, Qseven, COM Express compute modules based on Intel’s new Elkhart Lake Atom x6000E, Pentium, and Celeron system-on-chips. The German embedded vendor also unveiled a dozen Tiger Lake boards, joining its previously announced Conga-TC570 and Conga-HPC/cTLU Tiger Lake modules. We will cover these in separate reports and will focus here on the Pico-ITX form-factor Conga-PA7 SBC.

  • Congatec Unveils Atom x6000E Elkhart Lake Powered Pico-ITX SBC, Qseven, SMARC, COM Express Modules
  • Intel Tiger Lake UP3 COM Express Module Offers High AI Performance, PCIe Gen4 Interface

    Earlier today, Intel announces the Elkhart Lake IoT edge processor family, and quite discreetly more 15W Tiger Lake Core i3/i5/i7 UP3 processors designed for IoT & embedded applications, and with a configurable TDP from 12W to 28W.

  • Automate 35mm film scanning with Arduino and Python

    While taking photos today is normally a digital affair, there is a wealth of visual information stored on film negatives. Digitization is possible, but it tends to be rather time-intensive, so photographer/hacker Seckin Sinan Isik decided to automate the process.

    His setup uses a film carrier augmented with a stepper motor and belt drive to advance the 35mm film under a tripod-mounted digital camera. This is controlled by an Arduino Nano, with the camera’s view shown via a video capture device on a nearby computer.

  • Learning Greek with an arcade-style vocabulary reviewer

    Learning a new language is always a challenge, but can also be extremely rewarding. To help with this task — specifically learning Greek — Angeliki Beyko created an arcade-style review machine. Her device cleverly uses a sheet of pegboard to hold the electronics, including seven LCD screens to indicate category, level, and the actual Greek word being reviewed.

    Possible answers are shown as pictures on four TFT displays, driven by four separate Arduino Uno boards that pull up pictures stored on SD cards. An Arduino Mega provides overall control for the interactive panel.

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.
