    Qt Creator 5.0 is offering experimental use of Clangd as the back-end for Qt Creator's C/C++ code model. Clangd will ultimately be used for its code model rather than their existing libclang-based solution. Clangd can be used for providing code completion and other features with the Language Server Protocol. Qt Creator 5.0 is also bringing experimental support for building and running applications within Docker containers. The initial Docker integration is limited to Linux and with code-bases built using CMake.

  • The meaning of "hysteresis" and how it relates to alerts

    There's a lot of things in system administration where we want to prevent 'unwanted rapid switching', or unwanted rapid triggering of something, or the like. One way to do this is to not switch (or trigger or etc) if we've already done this recently. This means that the current state of the system depends partly on its history (whether there's been a recent switch), which is hysteresis.

  • Fixing an Interoperability Bug in LibreOffice: Missing Lines from DOCX (part 3/3)

    In LibreOffice, interoperability is considered a very important aspect of the software. Today, LibreOffice can load and save various file formats from many different office applications from different companies across the world. But, bugs are inevitable parts of every software: there are situations where the application does not behave as it should, and a developer should take action and fix it, so that it will behave as it is expected by the user.

    What if you encounter a bug in LibreOffice, and how does a developer fix the problem? In these series of articles, we discuss the steps needed to fix a bug. In the end, we will provide a test and make sure that the same problem does not happen in the future, again.

  • Roll your own Slack alternative

    Having an effective communication strategy is vital for every business, especially in the post-pandemic hybrid work environment.

    As IT teams scurried to draw up a list of collaboration tools to mobilize the remote workforce, Slack emerged as the favorite medium for communication due to its ease of use and cross-platform availability.

    But Slack isn’t the only game in town. Rocket.Chat is a viable alternative that is chock full of features. While Slack is a Software-as-a-Service (SaaS) app, you can host Rocket.Chat on your own IT infrastructure, without much effort.

  • Redis Labs Rebrands as Simply "Redis" - Database Trends and Applications

    Redis Labs has announced the company is now registered as Redis, dropping “Labs” from its name. According to the company, the change signals the maturation of the company and the Redis open source project, which it has contributed to since 2011 and sponsored since 2015.

    In addition, the company says, the name change also reflects the company’s mission to continue the growth of Redis as a real-time data platform. The company is focused on leading and steering alignment across the community, including individual contributors, customers, and partners, to deliver solutions to technical challenges and maintain its enduring popularity.

    The company adds that the renaming will not affect the licensing of open source Redis, which has always been and will continue to be BSD licensed, nor the governance model, which was introduced last year.

  • 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.
