The blog post discusses the author's frustrations with lagging in VSCode, particularly when using the Vim plugin, and issues with keybinding conflicts. After trying Zed, which also faced similar problems, the author opted for Neovim (nvim) in the terminal but was annoyed by the need to copy and paste file paths frequently. To effectively manage file navigation, especially with features analogous to VSCode's ctrl-click, the author developed a solution using tmux for enhanced terminal capabilities. The post highlights

Greer Jarrett, an archaeologist at Lund University, has identified four potential Viking havens along the Norwegian coast after sailing over 5,000 kilometers along Viking trade routes in replica boats. This research is part of a broader field known as experimental archaeology, which seeks to understand ancient technologies through practical experimentation. Jarrett's findings suggest that these havens were situated farther out to sea than previously known major ports, indicating a decentralized network significant for trade and travel during the Viking era. Other researchers in

In a blog post by Sam Estep dated June 23, 2025, the author discusses the importance of locality in programming to enhance performance. The focus is on how memory operations interact with different cache levels (L1, L2, L3) and how programs should be structured to optimize this interaction. Using an example of summing floating-point numbers based on indices from a second array, the author examines the performance differences between accessing the array in a sequential (first-to-last) order versus

The author explores the vibrant and unique small business culture in Japan, specifically highlighting tiny bars, izakayas, and specialized shops located in residential areas. They describe visiting quaint coffee shops in Kyoto, where coffee culture is more leisurely rather than grab-and-go. One particular spot caught their attention—a small coffee shop that doubles as a bar in the evening, located in a driveway between homes. The author appreciates the craft of coffee-making and notes the ease of starting small businesses in Japan, expressing plans to write

To make a Ruby class comparable (e.g., allowing expressions like `a > b`), you need to implement the spaceship operator `<=>` and include the Comparable module. For simple classes, like a six-faced Die, you can compare based on a single attribute such as the Die's value. However, for more complex cases, like a Die with varying numbers of faces, you want to prioritize higher values and more faces. A common method to implement the spaceship operator is using `Array#<

Undo/redo systems in creative software are essential yet often overlooked until they malfunction. Designing an effective system for Alkemion Studio, a visual brainstorming and writing tool for tabletop role-playing games (TTRPGs), presented numerous challenges but proved rewarding. The complexity stems from the multiple contexts users navigate, such as moving tokens, editing text, and adjusting metadata, which require a context-aware system to prevent confusion and potential bugs. Additionally, each undoable action serves as a structured autosave, emphasizing the

The article explores the history of Java, detailing its development by Sun Microsystems and key figures like James Gosling, Mike Sheridan, and Patrick Naughton. The aim was to create a universal programming language that could operate across various devices, but differing hardware architectures posed a challenge. To address this, they developed Java to compile code into an intermediate format called bytecode, which runs on the Java Virtual Machine (JVM), allowing for platform independence. The article also hints at interesting connections with oak trees,

The content discusses the importance of caching in system design for enhancing performance and scalability. However, it highlights the complexities surrounding cache invalidation, which can lead to serving outdated data if not managed properly, resulting in bugs and user experience issues. The author introduces the upcoming article's focus on cache invalidation fundamentals, including necessary strategies like write-through, write-behind, and time-to-live (TTL) approaches, especially in modern distributed systems. Additionally, the post mentions various resources and courses for those preparing for

The author recently submitted their PhD thesis and explored using Typst, a modern typesetting language, instead of LaTeX. They describe Typst as a blend of markdown and Rust, offering a comfortable writing experience without cumbersome syntax. One of the main advantages of Typst is its fast compile times, essential for maintaining focus while writing—compared to their friend's LaTeX setup, which took 90 seconds to compile. Typst allows for near-instant previews during document changes, making the
