  • Qt Creator 6 Beta Released With Updated C++ Code Model, Binaries Built Against Qt 6.2 - Phoronix

    With Qt 6.2 LTS having shipped at the end of September, The Qt Company is now turning their attention to Qt Creator 6 as the next version of their Qt/C++ focused integrated development environment.

    Qt Creator 6.0 Beta is out this morning as the first public test release of this Qt/C++ IDE. Qt Creator 6 Beta has moved launching of external processes to a separate server process for better handling on Linux and the C++ code model is re-based to that from LLVM 13.

  • 5 common bugs in C programming and how to fix them | Opensource.com

    Even the best programmers can create programming bugs. Depending on what your program does, these bugs could introduce security vulnerabilities, cause the program to crash, or create unexpected behavior.

    The C programming language sometimes gets a bad reputation because it is not memory safe like more recent programming languages, including Rust. But with a little extra code, you can avoid the most common and most serious C programming bugs.

  • Steinar H. Gunderson: Apache bug with mpm-itk

    It seems there's a bug in Apache 2.4.49 (or newer) and mpm-itk; any forked child will segfault instead of exiting cleanly. This is, well, aesthetically not nice, and also causes problems with exit hooks for certain modules not being run.

  • [Older] Creating a Python Makefile - Earthly Blog

    Even though Python is regarded as an interpreted language and the files need not be compiled separately, many developers are unaware that you can still use make to automate different parts of developing a Python project, like running tests, cleaning builds, and installing dependencies. It’s honestly an underutilized function, and by integrating it into your routine, you can save time and avoid errors.

    make is a commonplace tool in the world of software development, especially compiled languages like C or C++. It is a tool which controls the generation of executable and other non-source files from a program’s source file. It can automate the process of building software by tracking its dependencies and compiling the program only when the dependencies change.

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.
