  • SDL2 Sees Support For A Number Of Additional Controllers, Gamepads

    A number of additional game controllers / gamepads / input devices have been added to the SDL2 code-base in recent days.

    Sam Lantinga of Valve has been adding a number of new devices to SDL2 for proper mapping.

  • The 20 Best PHP Books To Master Your Skills in 2020

    PHP is well known as a general-purpose scripting language or open source scripting language that is used for the development of websites, either static or dynamic. Being easy to learn and use, fast performance, availability of online support, stability, security, and the open source advantages of the language, it has become a fascinating language for new and expert programmers. However, learning this language needs a good starting, continuation, and guidelines. So, we are here to provide a handful list of PHP books to serve the purpose of learning PHP.

    [...]

    For SDL2 on Windows, there is also now a Windows Gaming Input joystick driver for initially supporting the Razer Atrox Arcade Stick.

    The changes are currently staged in their development repository ahead of the next SDL2 update, likely later this year.

  • Marvell ThunderX3 Machine Model Pending For The GCC Compiler

    Last month Marvell announced the ThunderX3 server processors with up to 96 ARM cores per SoC and with 4-way SMT means up to 384 threads per socket. This 7nm Arm server processor also supports eight DDR4-3200 memory channels, 64 lanes of PCIe 4.0, and other advancements to provide more competitiveness in the Arm server space. Marvell is now working on getting the ThunderX3 software support ironed out, including for the GCC compiler.

  • It’s almost a day job…

    No, I really don’t care about C++. I’ve never been a C++ developer, I started using Qt 25 years ago through PyQt, and only started using Qt and C++ after a couple of years of Java.

    Back then, there was no standard library for C++, and from what I saw back then, there was an idea that to be successful a library needed to look like what seemed the biggest thing in software development back then: Java. I guess that’s where the original developers of Qt got their inspiration from, what with the Java-like iterators, QObject and QMetaObject so you could have an object hierarchy like in Java…

    An in the years since I started maintaining Krita, most people who came to the project, came without any knowledge of the C++ standard library. They tended to have used C# or Java at university, maybe Python or Ruby. Java-like Qt was easy to grasp, learn and use, even for people who really had never coded before.

    But of course, over the times, C++ evolved, to a point where I, since I’m just a linguist who has programmed for about forty years, cannot read “modern” C++ code anymore, not really. I mean, Ivan Čukić’ Functional Programming in C++ is wonderfully clearly written, but I’d be lying if I said I understood it, and it doesn’t seem to contain much that’s relevant for my day to day work on Krita.

  • Golang bindings for both libnbd and nbdkit

    I have to say for full transparency up front that Golang is not my favourite programming language, even less after using it for a while. Nevertheless with a lot of help from Dan Berrangé we now have Golang bindings for libnbd and nbdkit which are respectively client and server software for the Linux Network Block Device protocol.

    The Golang bindings for libnbd let you connect to a server and read and write from it. This is all pretty straightforward so read the manual page if you want to find out more.

    The Golang bindings for nbdkit are considerably more interesting because you can use them to write pretty natural and high performance NBD servers to expose “interesting things”.

  • Ramp up on Quarkus: A Kubernetes-native Java framework

    Java has been in a bit of an awkward spot since containers took off a few years ago. In the world of Kubernetes, microservices, and serverless, it has been getting harder and harder to ignore that Java applications are, by today’s standards, bloated. Well, until now. In this article, I explore the basics of Quarkus, a Kubernetes-native Java framework built to specifically address Java’s bloatedness problem.

    [...]

    Not to mention, as a language, Java gave organizations pretty much everything they needed to maintain software for a long time using a large team of professionals with varying levels of skills.

  • 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.
