A scholar named Carissa Chen, a Harvard University student, was conducting research to trace descendants of enslaved individuals linked to the university when she discovered Jordan Lloyd, a 35-year-old screenwriter. Chen had used historical records and genealogy to identify Lloyd as a descendant of Tony and Cuba Vassall, enslaved people connected to Isaac Royall Jr., a figure associated with the founding of Harvard Law School. In June 2020, while quarantined and reflecting on the novel "Roots," Lloyd

Emojis enhance the visual appeal of script outputs, especially when used sparingly. The VT100 terminal, introduced in 1978, allows for bigger text through DECDHL (DEC Double-Height Line) escape codes, enabling users to create larger, dual-line character displays. Users can test their terminal's support for DECDHL with specific keystrokes. When combined with full Unicode support, this feature allows for creative emoji combinations, such as merging different emojis to create new expressions. Although not

In a recent podcast episode, Vladimir Dementyev discussed his efforts to integrate Ruby on Rails into the browser, making it more accessible for users without requiring complex setup processes. Inspired by this, the author decided to try a similar approach with the Hanami framework, despite having little experience with WebAssembly (WASM). Initially, they managed to create a basic working version in about half an hour, but the process became challenging, leading to six more hours of troubleshooting and research. After overcoming various obstacles, they

Recent advancements in generative image models include two main categories: diffusion models (like Stable Diffusion) and autoregressive models (like OpenAI’s GPT-4o). Apple has introduced a potential third category with their work on Normalizing Flows (NFs), which have been somewhat overlooked recently. NFs transform real-world data into structured noise and can accurately calculate the likelihood of generated images, a feature that diffusion models lack. However, earlier NFs produced images that were often blurry and lacked detail

Git notes are a powerful yet underutilized feature within the Git version control system. They allow users to append metadata to commits, which can be particularly useful for tracking additional information without altering the original commit. This capability is beneficial for adding context to commits, as once a commit is made, its message cannot be changed in the history. Git notes can be applied to various Git objects, including commits, blobs, and trees. While they are often overlooked due to usability issues, engineers rediscover git notes

Daniel Lemire is a software performance expert recognized as one of the top scientists globally and a highly followed developer on GitHub. He notes that the upcoming C++26 will introduce compile-time reflection, which allows access to a program's own structure—enabling functionalities such as enumerating a class's methods or converting data structures to JSON strings efficiently. Lemire highlights that through his collaboration with Francisco Geiman Thiesen, the JSON library simdjson will leverage this feature, allowing seamless and performant conversions between

The message highlights the importance of feedback and its serious consideration. It discusses the Whitesmiths C compiler, first released in 1978, which was among the earliest commercial C compilers and adapted to the ANSI C standard by 1985. The compiler supported various architectures, including DEC PDP-11 and Intel 8086, and was often used as a cross compiler. P. J. Plauger, the company's president from 1978 to 1988, expressed his willingness to allow

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

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
