The content explores the relationship between understanding and appreciating mathematics through the lens of a number line, emphasizing that while mathematics can appear intimidating, it should be approachable and comprehensible. The author quotes John von Neumann, highlighting that familiarity in math can sometimes replace true understanding, which challenges the notion that math is merely procedural. They discuss the complexity of numbers, particularly those that exist between integers—termed "disintegers"—and suggest that these numbers hold deeper secrets than one might expect. The piece

The text critiques programming rules established for embedded software in expensive spacecraft, arguing these guidelines are overly restrictive and do not consider better alternatives like the SPARK subset of Ada, designed for verification. The author emphasizes the importance of critical thinking in programming, pointing out issues with C's exception handling methods (setjmp() and longjmp()), which are banned by existing rules. Although these rules ensure program termination, they can lead to impractical scenarios where completion takes an astronomically long time. The author highlights that transforming

In the late 2000s, a contributor to the Wii homebrew scene, part of Team Twiizers (later fail0verflow), developed software that allowed users to run unofficial apps on the Nintendo Wii. While passionate about their work, they burned out due to the high number of entitled users primarily seeking to use the software for piracy, which the team did not support. As newer consoles emerged, they shifted focus to Linux ports for fun, avoiding the community-building-heavy jailbreaks associated with

The article from *Scientific Reports* discusses how mitochondrial decline with age reduces ATP production, impacting cellular energy levels. Previous studies indicated that prolonged exposure to long wavelengths of light (650–900 nm) can partially restore ATP and improve cellular function. The study reports that short, single exposures (3 minutes) to 670 nm light can significantly enhance cone-mediated color contrast thresholds in aging adults (ages 37-70) for up to one week, achieving levels comparable to younger individuals. This effect appears to

In this post, the author reflects on their coding journey over a decade, focusing on increasing work speed and efficiency. They contrast two libraries they wrote: "strucjure" in 2012, which saw no usage, and "rematch" in 2018, which is still in production. Despite both libraries having similar functionalities, "rematch" was developed much faster, taking only a couple of months compared to over a year for "strucjure". The author estimates a

On February 14, 2025, Matt Carroll and Ricky Hanlon announced the deprecation of Create React App (CRA) for new projects and encouraged existing users to migrate to established frameworks. When CRA was released in 2016, it simplified the creation of React apps by integrating necessary tools and configurations into one package, which helped to streamline updates and feature deployments. However, the limitations of CRA for building high-performance production applications, coupled with the lack of active maintainers, led to this decision

The article discusses the Breadth-First Search (BFS) algorithm, a crucial concept in Data Structures and Algorithms (DSA), particularly relevant for technical interviews. BFS is used for traversing graphs or trees, exploring all neighboring nodes at the present depth prior to moving on to nodes at the next depth level. This approach is especially effective for finding the shortest paths in unweighted graphs. BFS begins at a designated vertex and utilizes a queue to track the vertices that have been visited but still have

The author acknowledges a long delay in continuing a blog series but expresses excitement about resuming it due to newfound interest from readers. The article will focus on applying previously learned concepts to the topic of convolution, specifically in image processing. It highlights image convolution as a simple yet effective area for exploration, noting its ease of implementation and the ability to create interesting visual effects, such as blurring images. The discussion will center around 3x3 convolutions, where an output pixel is calculated by combining its own

The author experienced an annoying faint white noise from their notebook's speakers, which was only noticeable in quiet environments when no audio was actively playing. After some investigation using the command related to PulseAudio on Linux, they found that the audio sink state could affect the noise: it was silent in the SUSPENDED state but could emit white noise in IDLE or RUNNING states. Despite having a setting to auto-suspend after inactivity, the sink often remained in IDLE without suspending. The author discovered

Gina has created a visual representation of her life, where each box on a map represents a week of her existence. Users can click on the boxes to see what she was doing during that week. The project is inspired by the "Life in Weeks" concept from Wait But Why, and she adapted the code from Buster Benson. Gina intends to continually update the map as her life progresses and includes a quote from Winnie the Pooh about moving forward in life.

In the past three weeks, the author, a contractor with over 20 years of experience, resolved several performance issues in a system that likely saved the company hundreds of thousands of dollars. He discovered these inefficiencies through intuition and experience, rather than traditional testing methods like unit or integration tests, which didn't show any issues. Using tools like VisualVM, he created test scenarios to accurately measure system throughput, identifying two problematic lines of code and achieving a tenfold increase in performance. His colleagues have benefited from
