Banish WFH Eye Strain: Optimizing Your Home Office Lighting

Working from home causing eye strain? Blogger Russell Baylis shares his journey to optimal lighting, emphasizing even, diffused light as key to reducing eye fatigue. He transformed his workspace with floor lamps and dimmable lights, eliminating harsh shadows and high contrast. Natural light is softened with diffusing curtains, and high-quality, flicker-free lighting is prioritized. The 20-20-20 rule and regular breaks are also stressed for eye health.

Unit Testing Reimagined: Beyond the Dogma

2025-02-15

Traditional unit testing often falls into dogma, leading to wasted time and ineffective tests. This article challenges the very definition of a 'unit', advocating for user-centric integration and end-to-end tests instead of rigidly testing every class or method. The author suggests reducing reliance on code isolation and mocks, leveraging real databases and tools like Docker for increased efficiency and meaningful tests. TDD is presented as not a silver bullet, with software architecture design prioritizing non-functional requirements. Ultimately, the key decision in choosing a testing strategy is balancing quality assurance, refactoring resilience, and speed of feedback; often, modern tools make fast e2e or integration tests feasible.

AI Agent Learns to Use Computers Like a Human

The r1-computer-use project aims to train an AI agent to interact with a computer like a human, encompassing file systems, web browsers, and command lines. Inspired by DeepSeek-R1's reinforcement learning techniques, it eschews traditional hard-coded verifiers in favor of a neural reward model to evaluate the correctness and helpfulness of the agent's actions. The training pipeline involves multiple stages, from expert demonstrations to reward-model-guided policy optimization and fine-tuning, ultimately aiming for a safe and reliable AI agent capable of complex tasks.

SpaceX Falcon 9 Launch Scrubbed 11 Seconds Before Liftoff Due to Delta Air Jet

A SpaceX Falcon 9 rocket launch was scrubbed with just 11 seconds to go on Sunday morning after a Delta Air Lines plane reportedly flew into restricted airspace near the launch site. The live broadcast of the launch showed the control room urgently calling "Hold, hold, hold!" as the launch was aborted at the 11-second mark. Investigations revealed the Delta Air Lines Boeing 767, en route from Los Angeles to Honolulu, flew over Vandenberg Space Force Base, the Falcon 9 launch site. The Federal Aviation Administration (FAA) will investigate how air traffic controllers allowed the Delta flight to enter the restricted airspace. This near-miss comes days after SpaceX's Starship rocket exploded, causing flight diversions.

Microsoft's Breakthrough: The World's First Topological Qubit

Microsoft announced a major breakthrough in quantum computing, unveiling Majorana 1, the world's first Quantum Processing Unit (QPU) powered by a topological core. Built using a novel topoconductor material, it's designed to scale to a million qubits on a single chip. This breakthrough leverages Majorana Zero Modes (MZMs) as qubit building blocks, employing measurement-based computation instead of traditional rotation, significantly simplifying quantum error correction. Partnering with DARPA, Microsoft aims to build a fault-tolerant prototype based on topological qubits within years, not decades, paving the way for a practical quantum computer capable of tackling real-world problems.

The Secret Spy Satellite That Helped Win the Cold War

The Secret Spy Satellite That Helped Win the Cold War

In the 1970s, the rise of the Soviet Navy posed a significant threat to the US. To counter the emergence of powerful new Soviet warships, the top-secret Parcae satellite program was launched. Developed by the US Naval Research Laboratory, Parcae provided real-time location data on Soviet vessels, drastically reducing the time between signal interception and intelligence reporting to mere minutes. This near-instantaneous intelligence was crucial for military decision-making. Employing multiple satellites working in concert and advanced computer systems to process massive amounts of data, Parcae helped maintain the strategic balance during the Cold War. Its technology continues to influence modern satellite signals intelligence systems.

Calculating Reciprocal Throughput in LLVM's Scheduling Model

2025-03-30

This post delves into the calculation of reciprocal throughput within LLVM's instruction scheduling model. LLVM's scheduling model describes an instruction with three key properties: latency, hardware resources used, and the number of cycles it holds each resource. While the traditional approach uses the maximum release cycle to calculate reciprocal throughput, this breaks down when non-zero acquire cycles are present. By analyzing resource segments and the instruction scheduling process, the author derives a new method: using the length of the longest segment across all hardware resources as the reciprocal throughput. This addresses the shortcomings of the traditional method when dealing with resource segments, providing a more accurate basis for performance optimization in the LLVM compiler.
