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
