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,

The article discusses the four deployment modes of Redis, a high-performance in-memory database widely used in distributed architecture systems. To enhance fault tolerance, deploying multiple Redis instances is essential, albeit more complex than using a single instance. 1. **Standalone Mode**: This involves installing and running a single Redis instance. It's suitable for scenarios where high availability is not crucial. - **Advantages**: Simplicity and ease of use. - **Disadvantages**: Lack of fault tolerance and high availability

The World Conker Championships is looking into cheating allegations after David Jakins, an 82-year-old competitor known as "King Conker," won the men's title for the first time since starting in 1977. During a post-victory search, Jakins was found with a metal replica conker in his pocket, which he claims he carries for humor and did not use in the competition. Competitors raised suspicions, particularly Alastair Johnson-Ferguson, who lost to Jakins

The author describes the creation of a unique acrylic square that, when illuminated, produces a 2D image and a 3D hologram. This phenomenon is based on "caustics," which are bright light patterns resulting from the interaction of light with transparent objects. The acrylic square achieves this effect through carefully engineered concavity and convexity on its surface, allowing refracted light to form distinct caustic images. The concept of caustics can be illustrated by a traditional convex lens, which

The article highlights the importance of precise interpretation of OAuth specifications, emphasizing that misunderstandings can lead to frustrating debugging issues. A common problem arises with the bearer token scheme in OAuth 2.0, where a simple case sensitivity error—using "bearer" instead of "Bearer"—can lead to confusing error messages, such as 500 - Internal Server Error or 401 - Unauthorized, when calling a third-party API. Many developers encounter this issue despite their code seeming correct. The article notes that

In 1963, philosopher Edmund Gettier challenged the longstanding philosophical definition of knowledge as justified true belief (JTB) in his influential paper "Is Justified True Belief Knowledge?" He presented cases, known as Gettier cases, demonstrating instances where a person could have a JTB that does not constitute knowledge. One example involves someone believing there is a cow in a field based on seeing a lifelike model, only to discover a real cow is coincidentally behind it. This situation highlights the
