Stephen Brennan • 09 May 2026 To my fellow Linux users who grew up using Windows XP: did you know, you can have Space Cadet Pinball on your Linux machine? This is not breaking news, but it’s exciting to me, and I’m the one who decides what I write about. So here’s your PSA! Space Cadet Pinball was bundled with Windows XP, and growing up I played it a lot. As a result it holds a special place ...
Emerich Juettner, a frail old immigrant, successfully printed nearly 10 years of crude one-dollar bills, evading authorities until 1948. He was sentenced to a year in prison and paroled after 4 months due to his lack of greed, and his story became a folk hero.

The linear theory of innovation is flawed as it assumes understanding precedes progress, whereas in reality, progress often comes from trial and error. This is evident in research and development where incomplete understanding is common and breakthroughs often result from observing and trying new things.
Gemini API's File Search tool now supports retrieval-augmented generation with multimodal data and custom metadata. It processes images and text together, improving search accuracy and transparency with page citations.
Internet Archive Switzerland launched as a non-profit foundation in St. Gallen to preserve endangered archives and AI models. It joins a global network of mission-aligned organizations to build a distributed digital library.

FreeBSD - a lesson in poor defaults This page lists some of the changes I make to a vanilla install of FreeBSD for security hardening. Some changes to increase network performance or make things a bit more sane are also included. It only covers basic changes that a sysadmin can make to a running system. It could also be considered a commentary piece on the state of security in FreeBSD's ...

A mathematician used ChatGPT 5.5 Pro to improve the upper bound on a problem in additive number theory from exponential to polynomial in time, with the AI producing a result that was almost certainly correct according to a human expert. The mathematician suggests that the era of human mathematicians solving problems independently may be coming to an end, and that the future of mathematics ...
The author argues that LLMorphism, the belief humans think like LLMs, may spread due to biased inferences and cultural influence. This bias could lead to undervaluing human cognition and overvaluing machine capabilities.
The author is creating a Go utility to manage Claude Code profiles but is frustrated with Apple's developer program requirements, including a yearly subscription and ID verification process that doesn't work well with their MacBook's webcam.
let-go is a Clojure-family language compiler and VM for Go that produces a single ~10MB binary with ~7ms cold start. It supports standalone executables, WASM web apps, and embeds cleanly as a scripting layer for Go programs.
BSA's decline is due to its national culture, which prioritizes career advancement over youth program quality and accountability. The organization's outdated programs and failure to adapt to developmental stages have led to a loss of relevance and market share.
Large Language Models (LLMs) degrade documents during long workflows, corrupting 25% of content on average. Current LLMs are unreliable delegates, introducing severe errors that silently corrupt documents over time.
The author is writing a history of Visual Basic on EvilGeniusLabs.ca, focusing on the people and lineage behind the language, rather than just its technical aspects or Microsoft management. The series will cover the development of Visual Basic from its roots in Dartmouth BASIC to its release in 1991, with a focus on lesser-known individuals who contributed to the project.
The user is creating a custom programming language called pslang for modding their game, aiming for a low-level, imperative language with a static type system and seamless C interop. The language has a unique syntax, including indentation-based scoping, built-in arrays, and a focus on simplicity and ergonomics, with the goal of making it easy to use for modders.
rlisp is a LISP frontend for Rust that compiles directly to Rust code. It uses s-expressions for syntax and compiles to native Rust with no runtime or GC.
Drop a needle of length $L$ onto a hardwood floor with floorboards of width $W$. On average, the needle crosses $2L / \pi W$ lines between floorboards, a classic result of Buffon. But that $\pi$ in the formula means there’s a circle hiding somewhere. The trick to finding it? Bend the needle into a noodle. The usual approach to Buffon’s problem involves a double integral. Respectable, but this ...
The user reflects on the early days of the internet and how the ideology of cyberlibertarianism, which emphasized individual freedom and deregulation, led to the creation of a platform that prioritizes profit over people and has devastating consequences. The user argues that it's time to face the facts that this ideology has failed and that we need to evolve and find a new ethical code to ...
The author rewrote a Finnish-English dictionary in Rust to reduce memory usage from 3 GB to 10 MB. They used a finite state machine to compactly represent the dictionary data.

Thirty-six US physicians signed a Congressional Record document stating President Donald Trump is mentally unfit for office. They invoked the Declaration of Geneva, citing concerns about his grandiose and delusional behavior.
The author explores the concept of surfels, a technique for rendering global illumination in real-time, and its application in a WebGPU-based pipeline, including surfelization, grid acceleration, and ray tracing. The pipeline is optimized with techniques such as guided sampling, multi-scale mean estimator, and temporal filtering to achieve a stable and noiseless image, but still faces ...
