The content discusses the Capability Hardware Enhanced RISC Instructions (CHERI) project, which aims to improve system security by rethinking computer architecture. Carl Shaw presented at the Linux Security Summit Europe about CHERI and its efforts to run Linux using this technology. He introduced the concept of capabilities, a mechanism for access control that has historical roots dating back several decades. The project extends instruction-set architectures (ISAs) to incorporate capabilities, which are unforgeable tokens that authorize use of resources. Originally proposed in

The author expresses concern about the decline of traditional blog posts discussing random topics, sharing insights on marathon running instead. They highlight the incredible achievement of completing a marathon in just over 2 hours, averaging speeds of 21.1 km/h (13.1 mph). This feat is likened to running a mile in 4:35 repeatedly or sprinting 100 meters in 17.06 seconds, which is well beyond the capability of most people. The author attributes this remarkable speed partly to human

A master carpenter holds on to worn wooden jigs in his workshop, which embody decades of craft and understanding. When a talented apprentice introduces a programmable machine that can create any shape, the master challenges her by asking for a chair. Although the machine produces a technically perfect chair, it lacks a certain essence or soul. The master demonstrates the value of his jigs, which convey experiences and memories of craftsmanship rather than mere possibilities. Similarly, communication can sometimes suffer from the barriers of language. In the

The author discusses their experiences working with clients who prefer not to use third-party libraries like ViewComponent, leading them to rely on Rails partials. While partials can be helpful initially, they often lead to challenges in maintainability and clean code due to excessive logic in views. The author expresses concern about the global scope of helpers and prefers using them only when applicable across the app. To address the limitations of vanilla Rails partials, the author introduces a custom helper designed to simplify the rendering of reusable UI

The article explores the extensive global journey and intricate processes involved in the production of smartphone processors, tracing their origins from quartz mines in Spain to advanced manufacturing facilities. It details that the quartz, primarily composed of silicon dioxide, is mined at Mina Serrabal, then transported to a factory in Sabón, where it undergoes rigorous heating in electric-arc furnaces to produce silicon metal. This silicon undergoes further purification processes, as it needs to reach a purity of 99.9999999% to

The author reflects on their 15-year journey with Bundler, a tool primarily associated with Ruby. They joined the team in February 2010 during the development of Bundler's 0.9 prototype, which eventually led to the release of version 1.0 in August 2010, alongside co-creators Yehuda Katz and Carl Lerche. The author's involvement grew as Carl and Yehuda moved on to other projects, and they began co-maintaining Bundler with Terence Lee,

Software development grapples with complexity, and developers strive to simplify challenging problems, leading to a concept called “self-trivialisation.” This involves creating solutions that abstract complexities, allowing tasks to become as simple as a single function call or library import. Essentially, developers aim to solve problems once, reducing the need for future efforts in that area. There are two approaches to software design: one focuses on simplicity to eliminate deficiencies, while the other complicates design to mask flaws. Self-trivialisation embraces the

A 67-year-old man named Tim Andrews is thriving more than six months after receiving a genetically modified pig kidney, marking a significant achievement in xenotransplantation—the transplant of animal organs to humans. The surgery, performed in January, has allowed him to remain dialysis-free after suffering from end-stage kidney disease. Andrews was one of three patients to receive these pig kidneys from the biotechnology firm eGenesis. Experts view the six-month survival as a pivotal moment, as this period is fraught with complications such

The provided content discusses the relationship between mathematics and programming, specifically focusing on type theory and equality. It explains how mathematical structures like natural numbers can be represented in programming languages like Haskell, but highlights the challenge of encoding laws that govern these structures due to different types of equality: definitional equality and propositional equality. Definitional equality is straightforward and part of the definition, while propositional equality requires formal proof, which can be more complex. In traditional mathematics, equality is treated as a binary
