The content serves as a web technology reference for developers, covering essential topics such as structuring web content with HTML, styling with CSS, scripting, building web applications, developing browser extensions, and ensuring accessibility. It emphasizes the need for developers to stay updated with changes in default user agent (UA) styles for nested section headings, as recent browser updates could lead to unexpected results. The HTML specification's outline algorithm assigns implicit semantic heading levels based on the nesting of sectioning elements, which has caused confusion among

The author has been experimenting with running large language models (LLMs) in their homelab without the need for a dedicated GPU or slow CPU processing. They chose to run NixOS with WSL on their gaming PC for its long-term convenience, including automated updates and quick rebuilding of the OS if needed. After facing challenges during setup, the author found solutions, particularly for automating the startup of WSL. They used a GitHub post for guidance, which works for Ubuntu but required adjustments

The KATRIN experiment has significantly revised the upper limit for the mass of neutrinos, revealing that they have a mass of less than 0.45 electron volts, effectively halving the previous estimate. Neutrinos are exceptionally light, initially thought to be massless, which poses a major question in particle physics regarding their mass and why they are so light compared to other particles. Conducted in Karlsruhe, Germany, the KATRIN experiment measures the energy of electrons produced in tritium radioactive

The post introduces "Inner Brew," a new section for personal reflections, alongside the author's experience writing the book "100 Go Mistakes and How to Avoid Them," published in August 2022. The journey began in 2018 while the author was working in Switzerland, where they and a colleague explored Scala and Akka for a project. Struggling with the complexities of Scala and Akka, they later turned to Go, which proved easier and allowed them to achieve their goals rapidly. After moving to

This PEP introduces "template strings" (t-strings) as a new way of handling string processing in Python, expanding on the existing f-strings with a 't' prefix. Unlike f-strings, which evaluate directly to strings, t-strings evaluate to a new type called Template, allowing developers to access and process the string and its interpolated values separately before they are combined. This feature promotes safer string handling, facilitating safety checks, web templating, and the creation of domain-specific

The author recounts their experience of compressing ELF executable files, motivated by the frustration that even minimal programs exceeded 4 KB in size. After research, they successfully reduced an executable to 45 bytes, claiming it was the smallest functional ELF executable on x86 Linux. Despite positive feedback, some commenters noted that shell scripts could achieve smaller sizes, to which the author emphasized that such scripts are not true executables when excluding interpreter size. Additionally, someone suggested that using the older aout binary format could

Vigilant is a website monitoring application that helps users track their DNS changes, lighthouse scores, broken links, and site downtime with customizable notifications. The current version, 2025.4, uses Calendar Versioning (CalVer) rather than traditional Semantic Versioning (SemVer) for several reasons. CalVer eliminates the arbitrary major version changes associated with breaking updates, reduces pressure for significant releases, provides a clear time context for updates, and promotes regular, incremental improvements. Unlike libraries that benefit from

The Y combinator is a key concept in lambda calculus that allows for the definition of recursive functions without self-referential definitions. This article proposes a different approach to explaining the Y combinator by first outlining its essence—enabling recursion without using direct recursive definitions—before deriving the traditional Y combinator itself. The author plans to describe a variation known as the Z combinator, as Y combinator requires non-strict evaluation found in languages like Haskell. The discussion is grounded in a lecture on

The content introduces a series aimed at demystifying async Rust, focusing on how it works rather than just how to use it. The series is intended for readers who have some experience with Rust, particularly with async functions and traits, but it promises to explain concepts like polling, pinning, and wakers in an accessible way. The author emphasizes the importance of understanding the `Future` trait, which defines entities that can be awaited, and highlights its complexity and significance in async programming. The series aims
