  • Computer science education for what purpose? Some perspectives
  • Coding an MSP430 From the Linux Command Line

    The MSP430 is a 16bit microcontroller made by Texas Instruments. As with many other embedded platforms I’ve been doing some work with it recently. In particular I started with the MSP-EXP430F5529LP development board which is what this blog post will be about.

  • KIMdle: Sorta-Wordle for the KIM-1

    Wordle mania (trademark, probably, of the New York Times) continues. My wife and I, who bonded over word games and later got married because that's how you pick a good life partner, play daily on a private instance, except that she's 19 hours ahead so she has to be careful not to give out spoilers. Retro has gotten into the action. There are Wordle ports for Windows 3.1, Palm Pilots, Game Boys and at least three versions for the Commodore 64, such as this, this and this poop themed one called Turdle, ha ha ha.

    Still, however, while these ports ditch dependence on JavaScript and HTML, they still rely on other modern conveniences such as, you know, a screen, a keyboard, and multiple kilobytes of RAM.

    You see where I'm going with this.

  • Live Streaming a Macintosh Plus (or Any Compact Mac)

    Since recording a handful of C Programming on System 6 videos, I’ve occasionally wanted to live-stream the more casual daily programming being done on my Macintosh Plus. After getting all of the pieces together, I now have a working self-hosted broadcasting setup.

    If I happen to be programming on my Mac right now, you can watch here at my website.

  • 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.
