digiKam 6.2.0 is released

digiKam try to be the most powerful with all files provided by digital camera. Raw files support is a big challenge. Some applications have been especially created only to support RAW files from camera, as this kind of support is complex, long and hard to maintain in time.

Raw files are not like JPEG. Nothing is standardized, and camera makers are free to change everything inside these digital container without documentation. Raw files permit to re-invent the existing, to implement hidden features, to cache metadata, to require a powerful computer to process data. When you buy an expensive camera, you must expect that the image provided are seriously pre-processed by the camera firmware and ready to use immediately.

This is true for JPEG, not RAW files. Even if JPEG is not perfect, it’s well standardized and well documented. For Raw, for each new camera release, the formats can change as it depends in-depth on camera sensor data not processed by camera firmware. This require an intensive reverse-engineering that digiKam team cannot support as well. This is why we use the powerful libraw library to post-process the Raw files on the computer. This library include complex algorithms to support all different Raw file formats.

  • 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.
