  • How-to: Writing a C shared library in rust

    All this information is great, but what I was looking for was a simple step-by-step example which also discussed memory handling and didn’t delve into the use of GObjects. I also included an opaque data type, but I’m not 100% sure if my approach is the most correct.

    I’m not going to discuss the entire subject of why you would want to do this. I’m thinking that if you’re reading this, then you already know why.

  • Patrick Griffis: Future of libsoup

    The libsoup library implements HTTP for the GNOME platform and is used by a wide range of projects including any web browser using WebKitGTK. This past year we at Igalia have been working on a new release to modernize the project and I’d like to share some details and get some feedback from the community.

    [...]

    Making the library smaller meant deleting a lot of duplicated and deprecated APIs, removing rarely used features, leveraging additions to GLib in the past decades, and general code cleanup. As of today the current codebase is roughly at 45,000 lines of C code compared to 57,000 lines in the last release with over 20% of the project deleted.

    Along with reducing the size of the library I wanted to improve the quality of the codebase. We now have improved CI which deploys documentation that has 100% coverage, reports code coverage for tests, tests against Clang’s sanitizers, and the beginnings of automated code fuzzing.

    Lastly there is ongoing work to finally add HTTP/2 support improving responsiveness for the whole platform.

  • memcpy.io | Upstream camera support for Qualcomm platforms

    CAMSS is a V4L2 (Video for Linux 2) Linux driver which focuses on supporting the basic use cases of the ISP, such as receiving the MIPI CSI-2 signals from the sensors, decoding them, and then writing them to memory. This leaves a lot of functionality typically provided by an ISP unimplemented, but that is intentional as the development priority has been to enable the data path from camera sensor to userspace.

  • bwidawsk.net 2.0

    I used plugins for my tables (multiple plugins). I used plugins for code highlighting. Plugins for LaTeX. Plugins for table of contents, social media integration, post tagging, image captioning and formatting, spelling. You get the idea. The result of all this was I ended up with a blog post that was entirely useless in its text only form. Plugins storing the data in non-standard places so it can be processed and look fancy.

    The WYSIWYG editor interface was a huge plus for me. I spent all day in front of a terminal breaking graphics and display (meaning I really was in front of an 80x24 terminal at times). I didn't want to have to deal with fanciful layout engines or styles. Those plugins ended up destroying the WYSIWYG editor experience and I ended up doing everything in quasi markdown anyway.

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.
