  • Embedded Linux for Teams | Ubuntu

    Developer-friendly embedded Linux should just deliver apps to devices. Satellite companies don’t build their own rockets. They focus on building satellites and lease a rocket to deliver it as a payload. Many developer teams also have to “build the rocket” to deliver embedded applications.

    Developers would be more successful, if Linux vendors made it their job to provide and maintain the scaffold that teams need to deliver embedded apps. In such a world, teams would focus on creating apps.

    The resulting app-centric development cycle could boil down to booting, building and deploying. Building on top of vendor-provided scaffolds, developers would create a bootable image for their target boards. Teams would then develop apps. After testing, they will build a system image that delivers all these apps. Then burn, deploy, done.

  • Run Pi-hole as a container with Podman on openSUSE - SUSE Communities

    There is arguably no better way to protect devices on your local network from unwanted content than Pi-hole. Add a machine running Pi-hole to your network, and it will quietly scrub all incoming traffic from pesky stuff like ads and trackers in the background. As the name suggests, Pi-hole was initially designed to run on a Raspberry Pi. But if you already have a machine running openSUSE on your network, you can deploy a Pi-hole container on it instead. And to make things a bit more interesting, you can use Podman instead of Docker for that.

    Installing Podman on openSUSE 15.2 is a matter of running the sudo zypper install podman command. A Pi-hole container needs the 80 and 53 ports, so make sure that these ports are available on your machine.

  • MorphESP 240 ESP32-S2 board integrates a 1.3-inch color display (Crowdfunding)

    We’ve already seen ESP32 platforms with a color display such as M5Stack, but MorphESP 240 is kind of cute with a 1.3-inch color display, features the more recent ESP32-S2 WiFi processor, and supports battery power & charging.

  • Rockchip RK3588 specifications revealed – 8K video, 6 TOPS NPU, PCIe 3.0, up to 32GB RAM

    Rockchip RK3588 is one of the most anticipated processors for the year on this side of the Internet with the octa-core processor features four Cortex-A76 cores, four Cortex-A55 cores, an NPU, and 8K video decoding support.

    The roadmap shows an expected launch date in Q3/Q4 2020, but sadly the release date will be pushed back in the future. Having said that, the Rockchip Developer Conference (RKDC) is now taking place, and the company has put up a poster that reveals a bit more about the processor.

  • Arduino Blog » Arduino psychic ‘magically’ guesses random numbers

    Standard Arduino Nanos can be used for many purposes, but they do not feature wireless capabilities. Somehow, though, Hari Wiguna’s Arduino psychic system is apparently able to pass data between two of them. No external communication hardware is implemented, yet one Nano is able to recognize when a random number chosen on the other Nano setup is input via an attached keypad.

    As noted by Wiguna, it’s easier shown than explained, and you can see this techno-magic trick in action in the first clip. How things work is revealed in the second video, but can you guess how it’s done?

  • 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.
