A distributed actor is defined as a single-threaded state unit available to applications within a distributed system. Despite their utility, many developers are unfamiliar with this concept, including the author, who took time to appreciate the actor model while working on Dapr, an open-source project featuring distributed actors. Notable implementations of distributed actors include Microsoft Orleans, which introduced virtual actors for .NET, Akka for the JVM ecosystem, and Cloudflare Durable Objects, although they don't explicitly use the term "actor."

The author, a professor and researcher in operating systems, discusses his hobby of developing MINIX and shares insights on the future of operating systems. He outlines two fundamental designs: monolithic systems and microkernel systems. - **Monolithic Systems**: These older systems consist of a single executable running in kernel mode, incorporating all components like process and memory management (examples include UNIX and MS-DOS). - **Microkernel Systems**: In contrast, microkernel systems operate with most components running as separate

The European Union is easing its regulatory stance on Big Tech due to intense pressure from the industry and the U.S. government, compromising key aspects of its General Data Protection Regulation (GDPR) and delaying important artificial intelligence (AI) regulations. The proposed changes would simplify cookie permissions within GDPR, making it easier for companies to share anonymized data and enabling AI firms to use personal data for training while adhering to other GDPR requirements. Additionally, the implementation of stringent rules from the upcoming AI Act will be postponed

The content discusses the tools UV and Ruff, both of which are built using Rust and designed to enhance code quality and dependency management in Python projects. UV serves as a faster, simpler alternative to traditional Python package managers like pip, virtualenv, Poetry, and pipenv. It handles project creation, dependency resolution, and script execution with remarkable speed, thanks to its use of a parallel SAT solver for dependency management and global package caching. This means it can complete operations in milliseconds, significantly reducing setup times compared

The content discusses the challenges faced by a client with a diverse portfolio of digital products, particularly in developing new features and scaling their engineering team due to poor architecture and accumulated technical debt from a Two-Tier Architecture. This architecture, which connects the front-end directly to the database, hindered growth. The author shares insights on migrating to a Three-Tier Architecture, which includes a middle layer for business logic, enhancing scalability and functionality. The distinction between the two architectures lies in the separation of concerns, with

On November 18, 2025, Cloudflare experienced significant failures in delivering network traffic at 11:20 UTC, resulting in error pages for users trying to access customer sites. The issue was not due to a cyber attack but rather a permissions change in a database system, which led to an unexpectedly large "feature file" used by their Bot Management system. This oversized file exceeded the software's size limit, causing it to fail. Initially suspected to be a DDoS attack, the problem

The content discusses the complexities of the three-body problem in classical physics and celestial mechanics, which involves predicting the motion of three bodies in space under mutual gravitational attraction. Unlike the two-body problem, which has a known analytical solution, the three-body problem lacks a general closed-form solution, necessitating numerical simulation as the primary method of study. A recent study by Li and Liao (2025) identified 10,059 new 3D periodic orbits. The simulation described utilizes Newton's law
