  • Make CapsLock useful (again) on Linux and Windows

    Once upon a time a post by Nikitonsky has inspired me to organize the hand movement on a keyboard by utilizing a CapsLock key. The idea is to use arrow keys without moving your hands from a default position, remapping the arrows to CapsLock + j/l/i/k. It’s been more than a year since I’ve tried that, and while I didn’t completely internalize this new layout (it’s hard to break habits!), it definitely has improved my typing experience.

    Nikita provides an excellent motivation for this endeavor in his blog post, so I won’t repeat it here. I’ll just describe a few additional changes made to this layout since I started using it: [...]

  • How To Build A Jekyll Site Using Simple.css

    As Bugs Bunny once said - that’s all, folks! We have come to the end of this rather long guide on how to build a Jekyll site using Simple.css and Netlify. This is by far the longest post I have ever written - at nearly 7,000 words, but I wanted to be as verbose as possible so that the barrier for entry is low. Some technical knowledge is always required when working with static site generators, like Jekyll. So please bear that in mind if you decide to give this a go.

  • usbkill the OpenBSD way

    So what is hotplugd, and how can it be useful? The man page does a good job of explaining it. Simply put: when any device is attached to or detached from your machine hotplugd will execute a script.

    To see how simple it is to write a hotplug script we can start by simply logging device attach events. First, start by enabling and starting hotplugd (as root): [...]

  • Decrypting TLS Streams With Wireshark: Part 3

    To make life easier for the recipients of your capture file with secrets file, you can also merge both files together: embedding the secrets into the pcapng file. This way, they don’t have to configure secrets files in Wireshark, just opening the pcapng file is sufficient for the TLS traffic to be decrypted.

  • Moving from Lubuntu 18.04 to 20.10 | Fitzcarraldo's Blog

    The Lubuntu developers will no longer be supporting Lubuntu 18.04, the final release of Lubuntu to use LXDE, after April this year. I therefore decided to replace it with Lubuntu 20.10 on the family desktop machine (a single-seat, multi-user installation).

  • How to Install NGINX on Ubuntu 20.04 and Host Website

    NGINX is an open-source web server software. You can deploy NGINX as a standalone web server, or as a proxy in front of other web servers (in essence, reverse proxy). Nginx is one of the best web servers to host a high traffic website.

    In this tutorial, we will focus on installing NGINX as a standalone web server on Ubuntu 20.04.

  • Automating responses to scripts on Linux using expect and autoexpect

    The Linux expect command takes script writing to an entirely new level. Instead of automating processes, it automates running and responding to other scripts. In other words, you can write a script that asks how you are and then create an expect script that both runs it and tells it that you're ok.

  • 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.
