  • tCam-Mini IR thermal camera board ships with ESP32 module

    While there are plenty of ESP32 camera boards, it’s much harder to find off-the-shelf solutions with ESP32 wireless SoC and an IR thermal camera.

    That’s likely why Dan Julio decided to design tCam-Mini board combining an ESP32 module with a Flir Lepton 3.5 sensor with 160×120 resolution to capture radiometric data for thermographic analysis.

    [...]

    It’s possible to connect to the ESP32 thermal camera board in access point or station mode to control it with “tCam console” desktop application compatible with Linux...

  • Cartesi (CTSI) Opens Linux Environment Gates for Avalanche

    Cartesi, the layer-2 decentralized Linux infrastructure announced its integration with Avalanche, the open-source platform for highly decentralized apps. With this integration, Cartesi’s Layer-2 infrastructure will expand within DeFi for the first time. Additionally, it will enable a Linux environment on Avalanche for smart contracts and higher computational scalability. Once the integration completes, the developers building on Avalanche will first time have access to develop smart contracts using Linux and uncountable mainstream software stack.

  • Official Evernote Application For Linux Available For Download (Beta)

    Let me start by telling you a bit about Evernote, in case you've never heard of it (which is weird, because this is a quite popular application). Evernote is an application for note-taking, organizing, task management, and archiving. Using it you can create notes using text, drawings, add photographs, audio, or web content. Each note can be tagged, annotated, edited, searched, given attachments, and exported. The application is free to use (but not free, open source software) with monthly usage limits, or you can use a paid plan. Up until recently, Evernote was available for Microsoft Windows, macOS, Android and iOS.

  • MySQL from Below

    When you insert data into a database and run COMMIT you expect things to be there: Atomically, Consistent, Isolated and Durable, like Codd commanded us 40 years ago, but also quickly. There is a surprising amount of sophistication being poured into this, but since I do not want to shame MongoDB and Redis developers in this post, I am not going to talk about that much in this place.

    We are instead trying to understand what our databases are doing all day, from the point of view of the storage stack.

  • 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.
