  • GL.inet GL-S10 - A compact BLE to MQTT IoT Gateway - CNX Software
  • Portwell COM Express Tiger Lake-H module supports 2.5GbE, PCIe Gen 4, 8K, up to 64GB DDR4 - CNX Software

    Portwell PCOM-B657VGL joins other COM Express and COM HPC modules based on Intel Tiger Lake-H Xeon, Core, and Celeron embeddded processors such as ADLINK Express-TL and Congatec conga-HPC/cTLH.

    Just like its competitors, the Portwell COM Express Type 6 Basic module offers 8K video output, PCIe x16 Gen 4, up to 64GB DDR4, USB 3.2 Gen 2, and 2.5GbE networking for a wide range of higher-end embedded applications such as industrial automation, medical equipment, graphics-intensive applications, and artificial intelligence.

  • M5Paper Gets Open Source Weather Display Firmware | Hackaday

    We know you like soldering irons, we’re quite fond of them ourselves. But the reality is, modular components and highly capable development boards allow the modern hardware hacker to get things done with far less solder smoke then ever before. In fact, sometimes all you need to finish your project is the right code.

    Case in point, check out the slick electronic paper weather display that [Danko Bertović] shows off in the video below. While it certainly fits the description of a DIY project, he didn’t have to put any of the hardware together himself. The M5Paper is an ESP32 development kit designed around a crisp 4.7″, 960 x 540 e-paper panel that includes everything from environmental sensors to an internal 1150 mAh battery. To make your handheld e-paper dreams come true, the only thing you need to provide is the software.

  • Palm OS: Reincarnate | Hackaday

    [pmig96] loves PalmOS and has set about on the arduous task of reimplementing PalmOS from scratch, dubbing it Pumpkin OS. Pumpkin OS can run on x86 and ARM at native speed as it is not an emulator. System calls are trapped and intercepted by Pumpkin OS. Because it doesn’t emulate, Palm apps currently need to be recompiled for x86, though it’s hoped to support apps that use ARMlets soon. Since there are over 800 different system traps in PalmOS, he hasn’t implemented them all yet.

    Generally speaking, his saving grace is that 80% of the apps only use 20% of the API. His starting point was a script that took the headers from the PalmOS SDK and converted them into functions with just a debug message letting him know that it isn’t implemented yet and a default return value. Additionally, [pmig96] is taking away some of the restrictions on the old PalmOS, such as being limited to only one running app at a time.

  • Issue #376 - Bullseye!

    My regular greeting is *finally* appropriate, as we announce the latest version of Raspberry Pi OS, named Bullseye. (Get it? Bullseye is the horse owned by Woody in Toy Story, who is a cowboy and says “howdy” all the time? Never mind.)

    We also gave Japan the good news that a Raspberry Pi 400 variant with a Japanese keyboard layout is now available to buy.

  • Arduino Certification Explained

    It’s aimed at educators who use (or want to use) Arduino kits in their middle school or high school classrooms. Arduino Certification is an online exam that tests your knowledge of electronics and programming. Students, makers, professionals and everyone in between can take the exam, too.

  • Video: Raspberry Pi OS Update

    Here's a new video from the Raspberry Pi Foundation regarding the upgraded Raspberry Pi OS that is now based on Debian 11. See also the blog post on the update.

  • 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.
