The author created a website, https://lowbackgroundsteel.ai/, in March 2023 as a resource hub for online content that hasn't been tainted by AI-generated material. The concept, termed "Low-background Steel," refers to uncontaminated metal, specifically steel and lead that is free from radioactive isotopes, typically sourced from ships sunk before 1945. The site aims to catalog text, images, and videos produced before the proliferation of AI content in 2022. Currently, it includes

The content discusses a scenario related to copy construction in C++ involving inheritance. It explains that the compiler determines whether a class (such as `Derived<int>`) is copy-constructible by checking for the presence of a non-deleted copy constructor. Although `Derived<T>` has a declared copy constructor, it relies on the copy constructor of a non-copyable base class (`Base<int>`), leading to an error when instantiation is attempted. The text highlights a discrepancy where the compiler considers `Derived

Mistral AI has announced its first reasoning model, Magistral, designed for enhanced domain-specific, transparent, and multilingual reasoning. Acknowledging the limitations of existing reasoning models, which often lack depth, transparency, and consistent performance in various languages, Mistral aims to improve complex problem-solving abilities through this dual-release model. Magistral is available in two versions: the open-source Magistral Small (24 billion parameters) and the more powerful enterprise-level Magistral Medium. Both versions exhibit

The author reflects on the rise of Docker and container technology since 2018, noting that it has become the standard for application deployment with backend apps incorporating Dockerfiles and Kubernetes YAMLs. Despite acknowledging the utility of containers for environment setup and safe execution, the author believes they are an overly complex solution that could be addressed by operating systems. The article explores alternatives to containerization, highlighting that containers are primarily used for cloud app deployment. Docker solves the issues of setting up stable environments with a consistent dependency tree

In this weekly newsletter, Stephane discusses the evolution of engineering management. Initially, small engineering teams had no formal leadership structure, often reporting to various stakeholders like PMs or founders. As teams grew, companies realized the need for dedicated management roles, leading to the promotion of senior engineers to dual roles of tech lead and manager, which worked for small teams but failed at scale. As teams expanded, the complexity of balancing coding with management tasks became apparent, prompting a separation of roles between individual contributors (IC

Liquid Glass is a new design paradigm introduced by Apple that enhances the user experience across its product ecosystem. It merges dynamic and expressive visual elements to create a flexible, organic interface that interacts intuitively with users. This design builds on historical elements from previous Apple interfaces, such as Aqua from Mac OS X and the fluid features introduced in iOS and other technologies. Liquid Glass is characterized as a digital meta-material that manipulates light in a way that mimics the behavior of liquid, responding fluidly to touch

Hexagonal Architecture and Clean Architecture are often regarded as distinct concepts, but they fundamentally represent the same principle: applying the Dependency Inversion Principle to separate business logic from infrastructure elements like databases and UI components. The core idea is to ensure that business logic, which drives profitability, does not directly rely on infrastructure. Two key frameworks illustrate this: Alistair Cockburn's hexagon model, where the application logic is inside the hexagon and everything else is outside, and Uncle Bob's concentric circles

The author has been exploring post-processing techniques to enhance their 3D work functionally, moving beyond mere stylization. They discovered that post-processing can significantly improve atmospheric and lighting effects in 3D scenes, offering a blend of efficiency and visual quality as these effects operate in screen space, independent of scene complexity. One specific effect that intrigued them was Volumetric Lighting, which creates beautiful beams of light, reminiscent of scenes in the game "Clair Obscur: Expedition 33." They

The text discusses the phenomenon where groundbreaking research papers, despite their potential to inspire new avenues of inquiry, often lead only to derivative work that fails to advance the core ideas. It cites two notable examples: the McCulloch-Pitts paper from 1943 on neural networks, which could have bridged connectionism and symbolic AI, and George Miller's 1956 paper, which revealed the limits of human memory. While both papers had significant implications for their fields, subsequent research mostly focused on minor

A recent report indicated a 47% decline in the number of applications on the Google Play Store. As a hobbyist Android developer working on MusicSync, a Google Play Music and Podcast replacement, the author shares their experiences in maintaining an Android app and explains why this drop in app numbers doesn’t surprise them. The author finds that maintaining Android apps is more complex compared to managing other side-projects with a limited web UI.

The content discusses a programmer who humorously named his weblog "The Boston Diaries" despite not living in or liking Boston. It then delves into the Forth programming language, focusing on the commands CREATE and DOES>. CREATE is used to establish new entries within the Forth dictionary, assigning them default actions related to their location in memory. For instance, when the word "MAN" is executed, it pushes the address of its body onto the stack. The example explores how the command SHAPE

Sophie Hardach explores the lingering radioactive traces left by Marie Curie in Paris, over a century after Curie's groundbreaking work with radioactive materials. Visiting the museum that houses Curie's historical lab and office, Hardach uses a Geiger counter to detect radioactivity on various objects, including a door handle and a chair, revealing Curie's direct interaction with radioactive elements like radium. The readings indicate low, non-threatening levels of radioactivity, well within safety limits. Curie worked in this lab from
