The article discusses the evolution of image capture from cave drawings to modern digital photography, emphasizing the significance of pictures in human experience. It explains the workings of digital cameras, starting from the basics of light detection. Unlike traditional film photography, which used light-sensitive silver halide crystals, digital cameras employ image sensors consisting of grids of photodetectors that convert photons into electric signals. The piece illustrates how varying the time for photon collection impacts the brightness of the image pixels and sets the stage for a deeper exploration

The discussed sorting algorithm has a worst-case runtime of \(O(n^{4/3})\) and utilizes the Fibonacci sequence to sort elements. This algorithm is a variant of Shellsort, which organizes the elements of an array through a process called \(k\)-sorting, where subsequences are sorted independently at defined intervals (gaps). For example, in \(3\)-sorting, elements are grouped based on every third element, leading to a \(k\)-ordered array, meaning that elements

In 2025, C++ and Rust emerged as the fastest-growing major programming languages, driven by the ongoing demand for efficient software that consistently outpaces hardware capacity. This trend stems from the historical pattern where software demands grow faster than hardware enhancements can keep up, as evidenced by significant tech milestones like the launch of iOS and ChatGPT. The primary constraints on computing growth in 2025 are power supply and chip availability, with power being the most critical factor. Major tech executives have highlighted that

Former Pixar CFO Lawrence Levy highlighted the company's enduring trustworthiness in an era of technological cynicism during a talk at CHM Live on November 20, 2025. Despite its success with 29 films over 30 years, Pixar faced significant challenges in the early days, including financial difficulties and a tough relationship with founder Steve Jobs. In spring 1995, just prior to Pixar's initial public offering (IPO), Levy recognized the dire situation: Pixar was struggling without profits, Jobs was in a

On December 31, 2025, a summary of developments in the LLM (Large Language Model) landscape over the past year was presented as part of an annual series. The year was marked by significant advancements, notably initiated by OpenAI's introduction of the reasoning technique, also referred to as inference-scaling or Reinforcement Learning from Verifiable Rewards (RLVR), beginning in September 2024 with models like o1 and o1-mini. This approach emphasizes training LLMs to achieve

The author discusses the concept of memory safety, criticizing attempts to define it as elusive and ineffective. Rather than providing a concrete definition, they aim to highlight flaws in existing definitions. The main argument posits that memory safety is an implementation property. Many definitions fail, such as one that equates memory safety with the absence of memory-access errors, which the author deems nonsensical (e.g., Java programs can dereference null pointers). Another definition proposed by Luca Cardelli mentions that a program

The author discusses the evolution of error management in modern programming languages, highlighting a shift toward a more structured approach as described in Joe Duffy's "The Error Model." Many languages, including C++, JavaScript, Python, Java, and C#, now utilize similar error handling constructs like throw, catch, and finally. Functional languages such as Haskell and Scala also incorporate exceptions, despite mixed feelings within their communities. In contrast, newer languages like Go, Rust, Swift, and Zig adopt a different error

An Associate Teaching Professor at Carnegie Mellon University reflects on their decision-making process regarding writing a book while gaining attention for their blog from 2020-2022. Although initially approached by major tech book publishers, they felt self-publishing would be a better route. However, after a conversation with an acquisitions editor who shared insights from his own successful publishing experience, the professor decided to pursue a traditional publishing deal. They collaborated with the publisher to craft a book proposal centered on classic programming projects, which not only
