  • Monitoring my home's air quality (CO2, PM2.5, Temp/Humidity) with AirGradient's DIY sensor

    The sensor package and board layout aren't perfect; the temperature and humidity sensor, in particular, is always a few degrees (F) higher than other known-working thermometers display. And the SenseAir S8 takes a couple weeks before its self-calibration routine finishes—until that's done, CO2 levels will likely show as being at least 200 ppm higher than they actually are.

    But after a few weeks, and after adding in a manual temperature adjustment to compensate for that sensor's inaccuracy, the AirGradient has been a very stable and helpful addition to my home environment monitoring.

  • The Postgres REPL

    R0ml Lefkowitz’s The Image of Postgres evokes the Smalltalk experience: reach deeply into a running system, make small changes, see immediate results. There isn’t yet a fullblown IDE for the style of Postgres-based development I describe in this series, though I can envision a VSCode extension that would provide one. But there is certainly a REPL (read-eval-print loop), it’s called psql, and it delivers the kind of immediacy that all REPLs do. In our case there’s also Metabase; it offers a complementary REPL that enhances its power as a lightweight app server.

  • 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.
