    We continued to ship Librem 5s throughout March all according to plan and also continue to hunt down CPUs. As we get more hardware confirmed we will contact the next group of Librem 5 backers with their shipping estimate and at the moment our pipeline is full well into May.

  • LilyGo sells Open-Smartwatch open-source hardware ESP32 watch by "Paul's 3D Things"

    We’ve previously covered three variants of LilyGo T-Watch-2020 smartwatch based on ESP32 WiFi & Bluetooth SoC with TTGO T-Watch-2020 (V1) launched about a year ago, following by T-Watch-2020 V3 with a microphone for voice control, and T-Watch-2020 V2 with GPS.

    The company has recently launched a new rounded smartwatch based on ESP32-PICO-D4 SiP with a twist as they did not design it themselves and instead partnered with “Paul’s 3D Things” for the Open-Smartwatch, and just handle manufacturing and production.

  • DehneEVSE is a custom, Nano 33 IoT-controlled EV charging station | Arduino Blog

    Sebastian Dehne decided to build a custom electric vehicle (EV) charging station for his Nissan Leaf from scratch, as what he calls “a real full stack project.” He notes that creating your own gives you total control over the system, and it’s both fun and cheaper than purchasing a ready-made device.

    The aptly named DehneEVSE is based on an Arduino Nano 33 IoT for control and current/voltage sensing, and connects via WiFi to a server that handles charging logic. UI consists of a web app that uses WebSockets to listen for real-time updates and display power consumption for all three phases. Aside from the stats, the app enables Dehne to turn charging on/off or to a low-cost setting, which regulates charge depending on the price of energy at a particular time.

  • 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.
