  • Using the Linux set command

    The Linux set command allows you to change the value of shell options or to display the names and values of shell variables. Rarely used, it is a bash builtin, but is quite a bit more complicated than most builtins.

    If you use the command without any arguments, you will get a list of all the settings—the names and values of all shell variables and functions. Watch out though! You’ll end up with a torrent of output flowing down your screen.

  • Rambling around foo: Stretch to Buster upgrade issues: "Grub error: symbol ‘grub_is_lockdown’ not found", missing RTL8111/8168/8411 Ethernet driver and RTL8821CE Wireless adapter on Linux Kernel 5.10 (and 4.19)

    I have been Debian Stretch running on my HP Pavilion 14-ce0000nq laptop since buying it back in April 2019, just before my presence at Oxidizeconf where I presented "How to Rust When Standards Are Defined in C".

    Debian Buster (aka Debian 10) was released about 4 months later and I've been postponing the upgrade as my free time isn't what it used to be. I also tend to wait for the first or even second update of the release to avoid any sharp edges.

    As this laptop has a Realtek 8821CE wireless card that wasn't officially supported in the Linux kernel, I had to use an out-of-tree hacked driver to have the wireless work on Stretch kernels such as 4.19, it didn't even got along with DKMS, so all compilations and installations of it, I did them manually. More reason to wait for a newer release that would contain a driver inside the official kernel.

    I was waiting for the inevitable and dreading the wireless issues, but since mid-august Bullseye became stable, turning Stretch into oldoldstable, I decided that I had to do the upgrade, at least to buster.

  • How to Clean the Package Cache in Arch Linux

    If you're wondering where your disk space went, the likely culprit is Arch's package cache. Arch Linux stores a copy of each package you download in the /var/cache/pacman/pkg/ directory. This includes every package you download, even upgrades. You can roll back to previous versions in case an update breaks a package, which comes in handy on a rolling-release distro like Arch.

    While having multiple copies of a package is useful for recovery, it does take up space. You might forget to remove older versions of packages. The developers of Arch Linux decided it would be better for the user to manage this cache rather than building some automatic utility to get rid of outdated versions. So how do you get your space back?

  • 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.
