  • AgVa Phone Ventilator Connects to a Smartphone to Fight COVID-19

    One major highlight during this COVID-19 crisis is the lack of enough ventilators for patients, a piece of critical equipment that greatly affects the breathing of critically ill patients. There are not enough ventilators available in hospitals right now for all of the potential patients who will be struck by the virus, so it is clear we need more ventilators. Makers are joining the call to service with their existing maker tools, and an example is the attempt to make a low-cost, open-source Arduino ventilator device.

  • Raspberry Pi Dev Server Manages Triple-Boot System With Help From Ubuntu

    This Raspberry Pi project covers all of your on-the-go developer needs. Designed by a developer known as CodeF.red, it uses a Raspberry Pi 4 running Ubuntu to help manage his triple boot laptop rig. With the portable dev server, he can easily swap between the Windows, macOS and Linux.

    The server is running Ubuntu off an NVME drive connected via USB (we have also detailed how to install Ubuntu on Raspberry Pi). The unit is controllable with a Bluetooth keyboard and also features a touchscreen. The maker also upgraded the Pi's cooling capabilities with a 5V Noctua fan with a super-low noise profile.

    The dev server uses Docker and can be controlled via SSH. Since it uses Ubuntu, you can add plenty of additional tools, like Glances for cross-platform monitoring features.

    Like many other Pi projects, the creator crafted this one using hardware already had on hand. CodeF.red said via Reddit that he considers the NVMe drive "overkill," especially since the performance is limited by the USB connection. But after removing the drive from an old Mac, it was gathering dust and needed to be put to use.

  • 3.5″ SubCompact SBC Leverages Intel Whiskey Lake Processor for Embedded & AI Applications

    The company provides Windows drivers for graphics, audio, I2C, touch controller, Ethernet, etc… Linux will certainly boot in the board, and I’d expect most features to work, but it’s still possible that some specific hardware features, like the touch controller, may not work properly or at all.

  • 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.
