  • celery-batches 0.5 released!

    A new version (v0.5) of celery-batches is available which adds support for Celery 5.1 and fixes storing of results when using the RPC result backend.

    As explored previously, the RPC result backend works by having a results queue per client, unfortunately celery-batches was attempting to store the results in a queue named after the task ID instead of the client ID (Celery internally calls this the “correlation ID”) [1].

  • The Best Free Photography Editing Applications in 2021

    We are all likely familiar with Adobe Lightroom or Photoshop as far as editing applications go and a lot of people love these apps for their versatility and powerful suite of features. But they do come with a price, and paying a fee isn’t always what every photographer is looking for.

    There are plenty of people who would like to find something equally capable of getting the job done that doesn’t run a monthly charge on their credit card bill or require a hefty up front payment. Thankfully, there are plenty of alternatives out there that run the gamut from beginner-friendly to as feature-packed as the name-brand products.

    [...]

    GIMP (GNU Image Manipulation Software) is flat-out one of the best editing applications available anywhere — for any price. Its suite of features is impressively full, and more are being added all the time.

    From layers, masks, and curves to brushes, clone stamps, and perspective changes, there is not a whole lot that GIMP can’t do compared to Adobe’s counterpart. Better yet, it is an open-source editor, meaning the huge community of users has created an extensive array of plugins that expand the functionality and abilities of GIMP. Some of these plugins come preinstalled, but there are tons more in its glossary that you can install in addition.

  • Screenshot And Annotation Tool Ksnip 1.9.0 Adds User-Defined Actions, Dockable Widgets And Other Improvements

    Ksnip, a feature-packed cross-platform screenshot tool that works with both X11 and Wayland, has been updated to version 1.9.0, getting the ability to add user-defined actions for taking screenshots and post-processing, dockable widgets, along with many other smaller, but useful new features and changes.

    Ksnip is a free and open source Qt5 screenshot tool that runs on Linux (X11, Plasma Wayland, GNOME Wayland and with this release, xdg-desktop-portal Wayland), Windows and macOS.
    The tool allows taking a rectangular area, full-screen, current screen and active window screenshots, with support for annotations. It comes with tools such as line, rectangle, ellipse, arrow, pen, marker (rectangle, ellipse, pen), text, text with arrow, auto numbers, and stickers, as well as the ability to scale or crop the screenshot after it has been taken. Optionally, the screenshots can then be uploaded to Imgur or a different image upload website with the help of the Ksnip built-in script uploader support.

  • 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.
