In the past, awnings were a common feature on buildings, including homes and significant structures like The White House, prior to the 1950s. They served an important purpose by blocking solar heat gain and facilitating passive heating and cooling, allowing for comfortable indoor temperatures without the need for modern technology. Awnings effectively shielded windows from high summer sun while permitting winter sunlight to warm rooms. Their design utilized solid construction and clever design principles of earlier builders. However, the prevalence of awnings has

Since the 1930s, archaeologists have explored the acropolis at Copan, creating nearly 4 kilometers of tunnels to study its construction phases. These investigations have revealed significant findings, including early stelae, plaster facades, and tombs, enhancing our understanding of the acropolis's history. A conservation plan led by Harvard, in collaboration with the Instituto Hondureño de Antropología e Historia, includes a digital 3D model of the tunnel system and focuses on preserving the

Engineer’s Codex is a publication focused on real-world software engineering practices. A notable quote from Linus Torvalds emphasizes the importance of data structures over code in programming: “Bad programmers worry about the code. Good programmers worry about data structures and their relationships.” Torvalds argues that well-designed data structures lead to easier design, maintenance, reliability, understandability, and readability of software. A strong data model not only simplifies application logic but also eases future migrations and system enhancements. The author

The article discusses the evolution of web application development and the various methods for storing data in users' browsers. Initially, web applications served static HTML, then evolved to dynamically rendered HTML and single-page applications that execute most of their logic on the client side. Currently, there's a trend towards building "local first" applications, which process complex data operations client-side and function offline, providing instant user interactions. Historically, cookies were the primary means of storing small key-value pairs, but modern JavaScript APIs have

The author is a full-stack Software Engineer skilled in React, JavaScript, and Rails, and has been working remotely for the past two years after founding a hyperlocal delivery startup in remote villages. They explain the use of the `attr_readonly` method in Rails, which marks model attributes as readonly, preventing changes after record creation. In Rails 7.1, attempting to modify a readonly attribute now raises an `ActiveRecord::ReadonlyAttributeError`, helping to avoid silent failures from previous versions.

In a discussion following a talk at PyGotham 2017, the author addresses a common misconception regarding Python's `range` object and iterators. They emphasize that while `range` (in Python 3) and `xrange` (in Python 2) are indeed lazy, they are not the same as iterators. This distinction is often misunderstood by both beginners and experienced programmers, leading to confusion about how these concepts function in Python. The author aims to clarify the difference

A recent study by scientists from the National Museum of Natural History and CNRS, published in the Journal of the Royal Society Interface, explores how birds can sleep while standing without losing balance. Unlike horses and cattle, which have four legs for stability, birds achieve this through a principle called tensegrity, where stability is maintained through a balance of tension and compression in their structure. Anick Abourachid, an evolutionary biology specialist, explains that the research focuses on the functional morphology of bird feet,
