  • Nicolai Hähnle: Can memcpy be implemented in LLVM IR?

    This question probably seems absurd. An unoptimized memcpy is a simple loop that copies bytes. How hard can that be? Well...

    There's a fascinating thread on llvm-dev started by George Mitenkov proposing a new family of "byte" types. I found the proposal and discussion difficult to follow. In my humble opinion, this is because the proposal touches some rather subtle and underspecified aspects of LLVM IR semantics, and rather than address those fundamentals systematically, it jumps right into the minutiae of the instruction set. I look forward to seeing how the proposal evolves. In the meantime, this article is a byproduct of me attempting to digest the problem space.

  • Netherlands: Participation app remains closed to the public

    The Dutch House of Representatives (Tweede Kammer) debates in public, as it should. But as not everyone has the opportunity to go to Den Hague and sit in the gallery, the Tweede Kamer released an app to follow the debates via livestream. Unfortunately, this app not is released under a Free Software licence. Our Dutch volunteer Jos van den Oever wanted to participate but was not able to run the app on his device and got active.

    In principle, it is a good idea to create and use technical solutions to increase the transparency of parliaments. However, the implementation in the Netherlands with the Debat Direct app is the opposite, as the app is not accessible to everyone. With the Debat Direct app, citizens can follow parliamentary debates easily from everywhere – but not with every device. The app is only available in the Apple, Google, and Microsoft app stores and is not available under a Free Software licence. A similar functionality is offered in an online webapp, Our Dutch volunteer Jos van den Oever wanted to participate and use the app on his Firefox OS phone - a Free Software operating system for mobile phones - unfortunately without success. Therefore Jos tried to get the app's source code in January 2018 in order to make it also accessible on other devices. It turned out to be a long fight.

    [...]

    Jos appealed with the newly discovered source maps, which resulted in a hearing on 17 March 2021. Jos was the plaintiff at the hearing at the highest general administrative court in the Netherlands, the Administrative Jurisdiction Division at the Council of State (CoS). In the hearing, the Parliament argued that the source maps do not contain the source code, even though Jos submitted the source code that he extracted to the hearing. On 31 March 2021, the CoS ruled that Parliament does not have to publish the source code since, in their judgement, the source code is not public. So even though it is factually public, via source maps, it is not legally public according to the CoS judgment. In other words: it is not public because Parliament says it is not public.

  • WordPress News – Gutenberg Highlights – WordPress.org

    During WordCamp Europe this past Wednesday Matt and I gathered to discuss the latest developments of Gutenberg and to share a video with some of the current and upcoming highlights. The video is wonderfully narrated by @beafialho and it was a great opportunity to celebrate all the incredible work that contributors are doing around the globe to improve the editing and customization experience of WordPress. For those that weren’t able to attend live it’s now available for watching online.

  • Best method for dark-mode friendly SVG in HTML

    In this article, you’ll learn about the different methods for embedding Scalable Vector Graphic (SVG) images onto webpages. I’ll discuss which methods support the various security and processing modes in SVG, which methods support dark mode using @media queries, and which are the most caching friendly. I’ll also touch on why the most backward-compatible embedding method is the worst for perceived performance and has the most accessibility bugs.

    SVG images have many benefits over other image formats. The file sizes can be tiny, they can be dynamic and interactive, and they can scale and adapt to fit any canvas size or application. However, web browser support for the format is incomplete, which further complicates SVG on the web.

    Let’s start with a quick refresher on the two SVG processing modes relevant to the web. Secure animated processing mode (SAPM) is the most-used and also the least feature-rich. As the name suggests, SAPM is a security-tightened subset of the SVG standard. It supports both native SVG- and CSS keyframe animations. It doesn’t support script execution, responding to interactions like clicks, nor remote loading of assets like fonts or other images. If you need any of these features, you need the dynamic interactive processing mode (DIPM).

  • 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.
