  • A Hare code generator for finding ioctl numbers

    Modern Unix derivatives have this really bad idea called ioctl. It’s a function which performs arbitrary operations on a file descriptor. It is essentially the kitchen sink of modern Unix derivatives, particularly Linux, in which they act almost like a second set of extra syscalls.

  • Open-source-as-a-service data tech startup scores $210m • The Register

    Finnish open-source-as-a-service provider Aiven received $210 million in funding this week, adding $1 billion to its nominal valuation in just nine months.

    The Series D cash injection – led by Eurazeo, and joined by funds and accounts managed by BlackRock as well as existing investors IVP, Atomico, Earlybird, World Innovation Lab, and Salesforce Ventures – follows $60 million Series C funding which valued the firm at $2 billion.

    The latest investment round values the company at $3 billion. It's remarkable considering it only supports open-source software and was worth $800 million when it got its first $100 million tranche of Series C funding in March last year.

  • ZUBoard 1CG - A low-cost AMD Xilinx Zynq UltraScale+ ZU1CG MPSoC FPGA development board - CNX Software

    Avnet ZUBoard 1CG is a development board featuring the new entry-level AMD Xilinx Zynq UltraScale+ ZU1CG dual-core Cortex-A53 MPSoC with 81K FPGA system logic cells, equipped with 1GB LPDDR4 RAM, as well as SYZYGY connectors and mikroBus expansion for Click boards.

    Priced at $159, the board may offer a good opportunity to get started with Zynq UltraScale+ MPSoC, as it’s quite cheaper than boards based on ZU3 devices such as Ultra96-V2 or MYD-CZU3EG. Avnet says the board is suitable for artificial intelligence, machine learning, embedded vision, embedded processing, and robotics applications.

  • The KDE Qt5 Patch Collection has been rebased on top of Qt 5.15.4

    I want to personally extend my gratitude to the Commercial users of Qt for beta testing Qt 5.15.4 for the rest of us.

    The Commercial Qt 5.15.4 release introduced some bugs that have later been fixed. Thanks to that, our Patchset Collection has been able to incorporate the reverts for those two bugs that affected Android and Windows and the Free Software users will never be affected by those!

  • Ubuntu Linux the number one Linux distro for gaming? Every time less - itsfoss.net

    The information on which this entry is based is a couple of weeks old, but it is worth not giving it up for lost because of the implications it has. It is about the advance in the imposition of Snap as an application format in Ubuntu, although just in this aspect it does not have the usual negative bias; but above all it is about how after many years of hegemony, we are beginning to see signs of the fall of Ubuntu as the flagship of the Linux desktop. Starting with the games.

    As they advanced on the Ubuntu blog, Canonical is packaging Steam for Ubuntu in Snap format, with “all the advantages that this entails”: a single package for all versions of the distro, dependencies included; and by dependencies they mention those of the Steam package, mainly the 32-bit libraries that caused so much controversy a few years ago, pitting the developers of Wine or Steam against those of Ubuntu, although as is known, everything ended well on the one hand and on the other. That and more.

    The Steam Snap will include, in addition to the 32-bit dependencies, some drivers for Mesa (OpenGL, Vulkan, and OpenCL, among others), make it easier to update the package, and provide other benefits, such as better security thanks to the confinement model of Snap. This, at least, is how Canonical sells it, all with the intention of positioning Steam Snap as the only option as of Ubuntu 22.10, in the absence of seeing if Valve withdraws the Deb package that they distribute officially. Meanwhile, a beta testing period is being promoted.

  • 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.
