  • Over:Board turns a Raspberry Pi Compute Module 4 into a mini-ITX motherboard (crowdfunding)

    The Over:Board is a mini-ITX motherboard designed to make it easy to use the CM4 in any mini ITX computer case. The developer is running a crowdfunding campaign for the project and says it should be ready to ship by September (although folks who want something sooner can reserve a prototype or pre-production unit).

  • C++ Standard Conversions

    There are two entity types in C++, the fundamental types and the compound types. The fundamental types are the scalar types. The compound types are the rest of the entity types. Conversion can take place from one entity type to another appropriate type.

    [...]

    The output is 2, 2, meaning that the program has returned the square root of 5 as 2 and the square root of 8 also as 2. So, the first two statements in the main() function have floored the answers of the square root of 5 and the square root of 8. This article does not discuss flooring or ceiling in C++. Rather, this article discusses the conversion of one C++ type to another appropriate C++ type; indicating any approximation in value made, loss of precision, or constraint added or removed. Basic knowledge of C++ is a prerequisite to understand this article.

  • Project Tour: Hashistack (Terraform, Consul, Nomad on AWS)

    I've always wanted to be able to set up a full consul, nomad, vault, etc. environment (along with hosted applications) with a single "terraform apply." I've spent a few weekends on this now and wanted to give a small tour, although it's still a work in progress.

  • Introspective labeling

    IRC is a good place to find answers. Often I find the questions found there to be even more enlightening.

  • 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.
