  • Clazy Framework Employed To Help Port Qt 5 Code To Qt 6 - Phoronix

    The Qt Company is now offering some checks for the Clazy framework to help in porting Qt 5 code to Qt 6 compatibility.

    Clazy is KDE's Qt-focused static code analyzer built atop LLVM's Clang. Clazy has been very useful for years in helping KDE/Qt developers discover bugs in their code and also help in some areas with automatic refactoring.

  • Porting from Qt 5 to Qt 6 using Clazy checks [Ed: Moving to proprietary software releases of Qt, which is no longer suitable for freedom-respecting developers]

    If you are looking for some help to port from Qt 5 to Qt 6, look no further. Within the Clazy framework, we've implemented some checks and fixits dedicated to help porting your Qt-based project.

    Those checks can be run using Clazy as a compiler plugin, using clazy-standalone on a .json file or from within Qt Creator.

    [..]

    First, you need to get Clazy or make sure your version is up to date. Version 1.10 will contain a corrected check for the deprecated API fixes, in the mean time please use the master branch.

  • Using Increment (++) and Decrement (–) Operators in Bash

    Similar to other programming language bash also supports increment and decrement operators. The increment operator ++ increases the value of a variable by one. Similarly, the decrement operator -- decreases the value of a variable by one.

  • Rakudo Weekly News: 2021.09 Best of Raku?

    Daniel Sockwell has started a discussion on what to do with the contents provided by the CCR Project with an idea to publish a “Best Of Raku” book. Modelled after books such as Coders at Work and Introduction to Best Software Writing, it would ask the Raku community to select 15-30 blog posts that do a good job of telling the story of the Raku Programming Language, thereby providing a good overview of what Raku is all about. Further suggestions, and other ideas, are very much welcome! And on a related note, 328 blog posts have been remastered so far!

  • Henri Sivonen: Rust Target Names Aren’t Passed to LLVM

    TL;DR: Rust’s i686-unknown-linux-gnu target requires SSE2 and, therefore, does not mean the same as GCC’s -march=i686. It is the responsibility of Linux distributions to use a target configuration that matches what they intend to support.

    From time to time, claims that Rust is “not portable” flare up. “Not portable” is generally means “LLVM does not support my retrocomputing hobby target.” This is mostly about dead ISAs like DEC Alpha. There is a side track about x86, though: the complaint that Rust’s default 32-bit x86 (glibc) Linux target does not support all x86 CPUs that are still supported by a given Linux distribution.

    Upstream Rust ships with two preconfigured 32-bit x86 glibc Linux targets: The primary one has the kind of floating-point math that other ISAs have and requires SSE2. “Primary” here means that the Rust project considers this “guaranteed to work”. The secondary does not require SSE2 and, therefore, works on even older CPUs but has floating-point math that differs from other ISAs. “Secondary” here means that the Rust project considers this only “guaranteed to build”. Conceptually, this is simple: x86 with SSE2 and x86 without SSE2. Pick the former if you can and the latter if you must.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
