  • Digging deep for responsible aluminum

    You probably don’t think about aluminum a lot. We do – it’s one of our 14 focus materials. But we really dug deep when we decided the Fairphone 4 was going to have an aluminum case rather than plastic. And it turns out, aluminum is really interesting.

    Start with this: It’s the most common mineral in the Earth’s crust. It’s forged in stars when magnesium picks up an extra electron. So when it comes to supply, there’s a lot of it. But it’s hard to make usable. In 1825, Danish chemist Hans Christian Oersted managed to produce the first malleable aluminum, but it was an outrageously expensive process. For decades, aluminum was as expensive as gold. Napoleon III’s state dinners were proudly served on aluminum plates, and his son waved an aluminum rattle.

    In 1886, two inventors simultaneously came up with a process in which aluminum oxide is melted in cryolite (sodium aluminum fluoride) and subjected to an electric current. And to this day, that’s how aluminum is made.

  • Open frame panel PCs offer a choice of V1000, Whiskey Lake, and Apollo Lake

    Ibase’s IP65-protected, 27-inch “OFP-W2700” panel PC runs Linux or Win 10 on a choice of Ryzen V1000, Whiskey Lake, or Apollo Lake along with SATA, 2x GbE, 4x USB 3.0, and up to 3x M.2.

    Ibase announced a 27-inch, open frame panel PC series that comes in three x86 flavors that support Linux Kernel 4+ or Windows 10. The OFP-W2700 series provides both portrait and landscape display modes. The semi-rugged, IP65-protected systems support both indoor and semi-outdoor environments for infotainment terminal and self-service kiosk applications. One image suggests the product is just the thing for a gym treadmill display.

  • ECS LIVA Z3 & Z3E mini PCs to ship with up to Pentium Silver N6000 Jasper Lake SoC - CNX Software

    ECS offers support for Windows 10 and Linux operating systems, and both models are most of the same specifications, except the thicker LIVA Z3E adds a 2.5-inch SATA bay and two RS232 DB9 ports. The new Jasper Lake lake model should be up to 35% faster than the “previous generation” which should be the LIVA Z2 based on Gemini Lake processors.

  • One board to rule them all: History of the Arduino UNO | Arduino Blog

  • 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.
