In the summary by Jacob Sheehy dated May 16, 2024, the author discusses using large language models (LLMs) like GPT-4o for effective code modifications. The post emphasizes how LLMs, particularly in chat formats, can degrade in performance when asked to modify existing code, often mixing new code with placeholders for old code. This makes it difficult for developers to identify changes and integrate them into their projects. The author suggests utilizing the API version of LLMs to

"Works on My Machine" is a newsletter focused on sharing insights about AI, relevant demo videos, and open-source code. In a recent video, the author demonstrates how to refactor a file by breaking the process into manageable tasks using Asana, which can then be transformed into pull requests (PRs) in a GitHub repository with the help of Gemini 2.0 Flash. The workflow involves analyzing the file to identify refactorable areas, generating a list of tasks, allowing for human

The importance of the join operator in SQL and relational algebra is emphasized as it establishes relationships between data sets, making it essential for most SQL-based applications. Epsio, a company developing a fast streaming SQL engine, seeks to optimize the implementation of joins for real-time query processing. The post focuses on the Symmetric hash join algorithm, commonly used in stream processing, particularly for inner joins. An example involving a bookstore's sales data illustrates how to connect customer and store sales tables through customer IDs. A

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 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
