In recent days, the author completed work on the UringMachine fiber scheduler, ensuring it is feature complete with all necessary hooks and behaviors implemented. They dedicated time to writing test cases for both the fiber scheduler and UringMachine's low-level API, as well as benchmarks to compare UringMachine's performance with other concurrency solutions. The results suggest that using the Fiber Scheduler can significantly enhance concurrent Ruby applications with minimal code modifications, such as replacing `Thread.new` with `Fiber.schedule`. The scheduler's

The text references previous articles about the challenges of email encryption, highlighting the little progress made since 1998. Encrypting email in both 1998 and 2025 involves similar steps with tools like GnuPG, but the situation has arguably deteriorated, particularly as web-based email has grown in popularity, which often lacks native PGP support. S/MIME, standardized around the same time as PGP, is more widely used in enterprises due to its hierarchical PKI trust model and better client

On December 12, 2025, it was noted that OpenAI has implemented a new Skills mechanism similar to Anthropic's, allowing various platforms to easily integrate skills, which consist of a folder with a Markdown file and additional resources. This functionality is available in OpenAI’s Codex CLI tool and ChatGPT, accessible via the "/home/oai/skills" directory. Users can create zip files of the skills folder, which includes tools for handling spreadsheets, documents, and PDFs. Notably

The content introduces uvm32, a minimalist, dependency-free virtual machine sandbox designed for microcontrollers and resource-constrained devices, implemented in a single C file without dynamic memory allocations. It runs on systems like STM32L0 with a low footprint (under 4KB flash and 1KB RAM) and serves as a RISC-V emulator. Uvm32 is aimed at executing custom script-like logic rather than simulating hardware. It provides tools for building efficient code and a simple VM host example

A team developed a comprehensive virtual reality (VR) setup for rats to play DOOM, featuring a motion-tracked treadmill ball, a panoramic headset, an input trigger, and a reward circuit. All components, including designs and software, are open-sourced for others to replicate. The project originated in New York with initial training of rats by Viktor, and after a pause, interest led to a more advanced version (v2) developed with engineers and collaborators to enhance documentation and accessibility. The hardware enables

The content critiques the idea that scientific progress has stagnated over the last 50 years, pointing out that this view is held by various individuals, including billionaire Peter Thiel and YouTube influencers, who acknowledge advances in computing but wrongly attribute them solely to industrial research. The writer emphasizes the crucial contributions of academia and government funding to advancements in computing technologies, particularly highlighting the historic roles of institutions like Bell Labs and Xerox PARC. The discussion then shifts to the evolution of LCF (Logic for Computable

The content describes the design principles behind the fish shell, which aim to balance user-friendliness with expressiveness, while adhering to POSIX standards where feasible. The fish design has three main goals: to enable all functionalities available in other shell languages, to be user-friendly without sacrificing power, and to follow POSIX guidelines as much as possible. Several specific design principles are highlighted to support these goals: 1. **Limited Orthogonal Features:** The shell should have a minimal set of distinct features to

The content provides a personal account of the author's experience with durable execution and its connection to task queues and orchestration systems, particularly in the context of managing Kubernetes deployments at Porter, a company where the author was CTO. Initially skeptical and unsure about the relevance of Temporal—an orchestration tool—the author struggled to understand its principles despite recognizing its potential benefits. Over time, after leaving Porter, the author conducted more in-depth research into durable execution platforms, even creating an open-source project with Temporal. The post

In May, OpenAI attempted to acquire Windsurf (formerly Codeium) for $3 billion, but the deal ultimately fell through. Recently, Anthropic acquired Bun, an open-source JavaScript runtime, although they could have built on it for free. This move suggests that companies in the AI sector are seeking to acquire engineering talent rather than replace them, contradicting the narrative that programming jobs are dying due to AI. The author argues that while AI has the potential to automate many programming tasks, the
