  • CSS: Avoid horizontal scrolling

    If you had told me last year that I’d write not one, but two blog posts about web design, I would not have believed you. Alas here we are, and I’m going to tell you about another pet peeve of mine and how to fix it.

    I view at least half the written content I consume via my mobile phone, which belongs to the class of phones with a slightly smaller than average screen. In fact, it’s width as reported by the Firefox and Chrome viewport simulators is 375 pixels wide, small but not tiny. And yet many websites I visit hinder my mobile viewing experience because of a rather simple issue: horizontal scrolling.

    There I am, happily reading a blog post or article from the front page of $NEWSAGGREGATOR. But suddenly I’m not scrolling down, but down-right and constantly have to scroll back to the left edge in order to read full sentences. My experience is even worse if the site for some reason has a minimum width larger than my screen is wide.

    Reading articles on those sites really cumbersome and more often than not I decide that it’s not worth the hassle to continue reading and move on to the next article. I find that quite sad, since the author invested time and effort to produce it, and the only reason I’m not reading is because of its subpar layouting.

  • OpenSSH ssh-agent Shielded Private Key Extraction (x86_64 Linux)

    While most of you guys were furiously grep-ing TermService memory for clear-text passwords I found myself searching for plain-text private keys in a ssh-agent process memory on a Linux box. Last time I did something similar was definitely before June 2019, when Shielded Private Keys were introduced in OpenSSH, therefore the tools I have available don’t work anymore.

  • 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.
