  • Joachim Breitner: A Candid explainer: Language integration

    Now for something completely different: How does Candid interact with the various host languages, i.e. the actual programming languages that you write your services and clients in?

  • Introduction to the QML CMake API

    When Qt 6 migrated to CMake, we also wanted to provide a nicer experience for setting up QML projects. With the initial Qt 6.0 release, we did however only provide some tech preview API, which did not do much more than what was available in qmake since Qt 5.15.

  • Translation Sadness

    Qt comes with translations for many things; applications can organize their translations into catalogs. To display a text, Qt applications will typically use the tr() function to look up a source-text and return a translation in the current language. For instance, tr("OK") will return the translation of “OK”.

    Translations have a context, which in the case of a naive call to tr() is generally the class name performing the call. This gives the translations at least the opportunity to change the way “OK” is translated in the context of classes MyFancyWidget or MyAwkwardDialog.

    So a catalog will basically be a table, helping to look up string in context to produce a translation.

    [...]

    My remaining sadness is that Qt is almost there, and documentation says that it should all work, and that in the end I need to pull off some stupid hack to provide the right display of a 2-character string (2 glyphs in Simplified Chinese, 5 in Turkish). At least it’s documented, and the next time someone files an issue that there’s a missing translation I have a handle on what kind of code to add.

  • opensource.com: What was your first programming language?

    My first ever programming language was BASIC in the early eighties. One of my relatives bought a C64 for their kids to get started with learning computers. They only used it for gaming, and I was also invited. But they also had a book about BASIC, and I was curious and gave it a try. I wrote some short code, I did not even know how to save it, but it was exciting to see that the computer does what I say to it. This means that I was not paid to learn it, and it was not my choice. It was the language available to me. Obviously, when I got my first computer a few years later, an XT compatible box, I first wrote some code in GW-BASIC, the dialect of BASIC available with DOS.

  • Programming languages: Python is on the verge of another big step forward

    Tiobe, a software testing company, bases its rankings on searches for programming languages on popular websites and search engines. The Tiobe index is updated monthly, and it doesn't align with other language popularity rankings. For example, the electrical engineering magazine IEEE Spectrum has ranked Python as the most popular language since at least 2020, followed by Java, C, and JavaScript, while developer analyst RedMonk has JavaScript in top place, followed by Python and Java, and places C at tenth.

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.
