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 However, it highlights the complexities surrounding cache invalidation, which can lead to serving outdated data if not managed properly, resulting in bugs and user experience issues.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 content discusses the polystate library, which facilitates the creation of Composable Finite State Machines (FSMs). It emphasizes the importance of user feedback and encourages communication for any clarifications. The library aims to enhance programming through composability and type safety, making FSMs more effective. It provides instructions for downloading and adding polystate as a dependency in projects, along with examples to illustrate its usage. The author acknowledges the effort in explaining the library clearly and offers support for any questions. A basic example

This week's newsletter, sponsored by Cerbos, focuses on securing non-human identities (NHIs) in the context of AI agents and microservices. An accompanying ebook outlines a roadmap based on Zero Trust principles, detailing real-world NHI security threats, governance principles, and a vendor evaluation checklist to enhance NHI security. The newsletter also discusses a recent article analyzing the state of engineering leadership, highlighting a troubling trend where 51% of engineering leaders now perceive AI negatively, an increase from 42%

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

The article discusses lesser-known features of POSIX shells, highlighting the importance of writing portable shell scripts rather than relying on Bash-specific features. The author shares useful tricks for common tasks, such as removing prefixes and suffixes from filenames, which are applicable in any POSIX shell. They emphasize that these methods do not involve external commands like `basename` or `dirname`, making them faster and more efficient, especially on platforms like Windows where forking is costly. The author encourages the use of these POSIX

The author expresses frustration with the internet, listing its distractions, ads, and negative content, yet acknowledges its importance as a software developer and a means of communication. Despite a neutral view towards the internet, the author aims to mitigate its negative aspects, especially the addictive nature of social media. Attempts to block social media have failed, partly because of the author’s wife needing it for work and their shared struggle with moderation. A proposed solution involves adapting a clever idea from Neil Chen on Hacker News, which uses

The document discusses the addition of captureless lookbehinds to the RE2 regex engine, which operates in linear time. Modern regular expressions have become intricate, featuring elements like backreferences and lookarounds, which traditionally required backtracking engines with worst-case exponential complexity. Recent advancements, however, demonstrated that lookarounds can be executed in linear time without backtracking. The original research provided two implementations, one in OCaml and another on the V8 JavaScript engine. The current document presents a third

The author describes their experience creating and updating a simple analog clock project initially built with JavaScript for functionality. They aim to convert it into a purely HTML and CSS-based clock while addressing the issue of the clock resetting to 00:00:00 upon page load. To keep the clock in sync with the current time, they suggest using a negative value for the `animation-delay` property in CSS, which allows the clock to start at the current time without JavaScript. For the server-side implementation
