The author aims to leverage Go's concurrency and parallelism for projects requiring significant number crunching but seeks even greater performance through SIMD (Single Instruction Multiple Data) capabilities at the hardware level. While many programming languages support SIMD through compiler optimizations or libraries, the author notes that Go's compiler does not utilize SIMD and could not find a suitable general-purpose SIMD package. Thus, they decided to create their own package that provides a thin abstraction layer for arithmetic and bitwise SIMD operations. During their research, they

The article discusses the Rack protocol, which defines how Rack servers, applications, and middleware interact. It clarifies that while the rack gem provides helpful development tools, using it is not mandatory for creating Rack components; as long as they comply with the Rack protocol, they are considered Rack servers, applications, or middleware. The article focuses on understanding these components through practical examples, including building a dummy Rack server. A Rack server's main role is to act as an HTTP server, handling requests and responses,

Ruby is recognized for its flexibility and metaprogramming features, particularly the `instance_exec` method. This method allows developers to execute a block of code in the context of an object's instance, which is especially useful in Ruby on Rails applications. By utilizing `instance_exec`, developers can access instance variables and methods that would normally be inaccessible outside the class. The method belongs to the Object class, so it is available to all Ruby objects. It accepts a block and optional arguments, enabling dynamic code execution

When developing or porting a PC game, handling user input from the mouse, keyboard, and gamepads is crucial, yet it can be quite complex, particularly concerning mouse and keyboard in Windows. Many popular AAA games experience significant mouse input issues, especially with high-end mice, and some game engines have ongoing problems in this area. The article examines the challenges related to mouse input, notes the complexities of integrating other accessories like steering wheels and flight sticks (though these are not covered), and suggests that those

For the past seven years, the author has been advocating for public access to 3D scans of collections from French national museums, beginning with the Rodin Museum in Paris. This campaign has escalated to involvement with France's highest administrative court, as the museum and Ministry of Culture allegedly attempt to obstruct access and violate freedom of information laws. In contrast to this, many global museums share their high-quality 3D scans, enabling public interaction, adaptation, and use of cultural heritage. Examples include the

The article discusses the rise in popularity of PDFs as data sources in the context of large language models (LLMs) and the challenges of querying them. It introduces pgPDF, a PostgreSQL extension designed to facilitate querying PDFs directly in SQL. The author explains that PDFs are typically parsed into text using tools like `pdftotext`, but pgPDF offers an alternative approach, allowing users to perform queries on the filesystem. To use pgPDF, several packages (poppler, glib, and cairo

In a disturbing incident at Baptist Health hospital in Richmond, KY, organ preservationist Natasha Miller observed a donor who had been declared dead exhibiting signs of life, including thrashing and visible tears. This situation alarmed the medical staff, including the surgeons, who refused to proceed with the organ retrieval. Amid the chaotic environment, the case coordinator sought guidance from her supervisor on how to proceed but faced pushback and was upset due to the circumstances. Ultimately, the organ retrieval was canceled. Following this incident in

The content discusses the concept of creating a new village 90 minutes north of San Francisco, designed to foster a community similar to a college campus, where families and children can learn, explore, and engage in various activities together. The idea emphasizes a more connected and enriching environment for families, allowing children to roam freely while parents can enjoy less stressful roles. The vision is inspired by Chautauqua, New York—a historical village that combines aspects of a college campus and a family summer camp, encouraging walking

Joeri Sebrechts discusses the rising popularity of signals in various web frameworks like Angular, Solid, and Preact, with proposals to include them in the core language. Signals allow developers to wrap values and computations, enabling efficient responses to changes without necessitating full application rerenders, unlike traditional approaches in React. Sebrechts encourages vanilla web developers to utilize signals, explaining that they can be implemented using the EventTarget class. He initially presents a basic implementation of signals before suggesting enhancements for cleaner and more user-friendly

On February 14, 2016, Ryan Petersen discussed the origins of DHL, which began in 1969 as a courier service that utilized travelers' spare luggage capacity to transport high-value documents. To address delays in delivering necessary shipping documents due to containerization—introduced in the mid-1960s, which enhanced shipping efficiency but complicated document delivery—DHL offered free plane tickets to individuals willing to carry these documents in their luggage. This innovative approach allowed DHL to facilitate faster document transfer, resolving
