  • WordPress Site Health - cURL error 28 (REST API, loopback)

    It is obvious that the problems in Site Health are internal - after all, they only started cropping up with the move to WordPress 5.4. Of course, some piece of code somewhere has changed, but then, essentially, if a core product behavior is suddenly radically different than it was just before the update, and there are no huge problems in the other elements of the site's functionality, then it's quite likely the issue stems from said core product update.

    I do like the idea of this site-issues-at-a-glance kind of thing, but I am not happy with the false positives, or the goose chase that the errors have created for me, even if only briefly. Errors need to be meaningful. If I have no insight what might be wrong from the way the error manifests, then there's really no point showing the technical details. The cURL error 28 and .htaccess seem so far apart. Anyway, here we are. If you're affected by a similar problem, have a look at your site configuration, see if you're using basic auth, and perhaps suffering from the same would-be bug. We're done here.

GNOME Adds Bit To Launcher Files For Indicating Apps

  • GNOME Adds Bit To Launcher Files For Indicating Apps That Should Run On Discrete GPUs

    The GNOME Shell has long provided the ability for easily launching applications on alternative GPUs namely for multi-GPU/Optimus-type setups especially with the increasing number of laptops having both integrated and discrete graphics. GNOME is now introducing an addition to .desktop files so applications can specify if they should run on the dedicated GPU if available.

    GNOME developers have introduced a new PrefersNonDefaultGPU entry key to the .desktop file specification for launching programs. This allows for automatically launching the application on discrete GPUs for PRIME-enabled setups. This is basically a hint for the shell to activate running the GPU on the dGPU rather than the user having to right click on the application and opt for launching on the alternative GPU. For those with single GPU systems, this new option will have no impact on you.

The Linux 'Desktop Entry Specification' gets a way...

  • 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.
