  • A New KiCAD Tutorial Hits The Scene

    KiCAD has a rightfully earned image problem regarding beginners. The shiny new version 5 has improved things (and we’re very excited for v6!) but the tool is a bit obtuse even when coming from a electronics design background, so we’re always excited to see new learning material. [Mike Watts] is the latest to join the esteemed group of people willing to export their knowledge with his KiCAD tutorial series on GitHub that takes the aspiring user from schematic through fab and assembly.

  • Alibaba’s open source processor targets complex cloud workloads like 5G

    If demanding telecoms workloads like virtualized RAN and 5G core are to move to the public cloud, the cloud providers will need to ensure their infrastructure is based on processors capable of supporting these functions. Suppliers like Intel are already investing in accelerators to surround their processors, for cloud hardware that can cope with artificial intelligence (AI), vRAN and other very high performance tasks. But in some cases, the webscalers themselves are also designing or commissioning their own processors to meet the demands of the new generation of cloud-based services and make sure their clouds are a match for specialized private cloud platforms. Google, Amazon AWS and others have periodically announced such developments, raising new challenges for Intel and other…

  • A digital tally list for hackerspaces

    Overall our plan is to write a digital tally list in two weeks, going from idea to running prototype. This tally list should support donations with a variable amount, drinks with set price, as well as assorted items like the workshop fee. It also needs to support rudimentary user management and some kind of admin interface. All users will be verified by RFID.

    Currently consumption is logged into a monthly log-file, so we can easily handle the payments. Users are managed by the UI itself, we just have to put the initial UID into a json file. Drink prices are read from JSON and a price update requires a restart of the app. The app itself will run on a Raspberry PI with an attached 7" display and an RFID reader attached via the serial port.

    The entire app is written in Python with a QML frontend.

    I'm ordering the RFID hardware and the display this week, so we have a full weekend of hacking ahead of us.

  • Snapdragon 410-based module offers 96Boards and touch-panel eval kits

    Keith & Koep’s tiny, Linux-ready “Myon I” module features the quad -A53 Snapdragon 410 with up to 8GB eMMC, extended temp support, and an optional WiFi/BT/GPS module. The Myon I powers a “ConXM” carrier and “i-PAN M7 CoverLens Touchpanel PC.”

    Keith & Koep, which offers a line of SODIMM-style “Trizeps” computer-on-modules such as the recent i.MX8M-based Trizeps VIII and i.MX8M Mini-driven Trizeps VIII Mini, is introducing a Myon I module with a smaller 48 x 32 x 4.2mm footprint and no edge connector. While the Trizeps line started out with Marvell XScale processors before moving on to Freescale/NXP i.MX SoCs, the Myon I taps Qualcomm’s Snapdragon 410.

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.
