  • Jussi Pakkanen: "Should we break the ABI" is the wrong question

    The ongoing battle on breaking C++'s ABI seems to be gathering steam again. In a nutshell there are two sets of people in this debate. The first set wants to break ABI to gain performance and get rid of bugs, whereas the second set of people want to preserve the ABI to keep old programs working. Both sides have dug their heels in the ground and refuse to budge.

    However debating whether the ABI should be broken or not is not really the issue. A more productive question would be "if we do the break, how do we keep both the old and new systems working at the same time during a transition period". That is the real issue. If you can create a good solution to this problem, then the original problem goes away because both sides get what they want. In other words, what you want to achieve is to be able to run a command like this:

    prog_using_old_abi | prog_using_new_abi

    and have it work transparently and reliably. It turns out that this is already possible. In fact many (most?) people are reading this blog post on a computer that already does exactly that.

  • Qt Developer Conference

    We at KDAB are pleased to announce an event we’re planning to host in Berlin this fall, September 28-30. Save the dates for KDAB’s Qt Developer Conference — a conference from Qt developers for Qt developers!

    Qt Desktop Days, May 2021 — Cancelled

    Before we tell you more about Qt Dev Con, we’d like to let you all know, or confirm what you may have already heard, that the Qt Desktop Days conference that we were planning for this month has been cancelled. This was due to the dates of the event coinciding with those of a couple of other big events. We’d like to try to give you all a better chance to attend more conferences, rather than having to miss out on one or two of them. Therefore, the desktop aspect of Qt development will be integrated into our Qt Developer Conference in the fall, instead.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
