The website GPS Satellites Tracker provides real-time tracking of GPS satellites orbiting Earth, displaying their positions, orbits, and status. It offers live data and visualizations for monitoring the Global Positioning System satellite constellation.
Background
GPS (Global Positioning System) is a U.S.-owned satellite network originally developed by the Department of Defense for military use, opened to civilians in the 1980s. The system relies on at least 31 active satellites in medium Earth orbit (~20,200 km altitude), each broadcasting precise timing signals. A GPS receiver locks onto signals from four or more satellites to calculate its position via trilateration. The network is maintained by the U.S. Space Force; its nominal constellation exceeds the minimum of 24 satellites needed for global coverage. The article appears to be a real-time tracker showing current positions, orbital paths, and status of each GPS satellite — useful for understanding coverage, satellite health, and the constellation's geometry at any given moment.
Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.
Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.
Roman Storm warns that the legal theory in his case could set a precedent making open-source developers liable for how others use their code, potentially criminalizing the mere publication of privacy, messaging, or crypto tools. He notes that developer Michael Lewellen cannot publish lawful code due to prosecution fears, and argues this chilling effect extends beyond any single case.
Meta's engineering culture is deteriorating under Mark Zuckerberg and Scale AI CEO Alexandr Wang, who have introduced keyboard tracking, reassignments to data labeling, and AI-centric performance metrics. Critics argue this incentivizes performative AI use, drives away experienced engineers, and contributed to a major Instagram hijacking incident caused by AI-written and AI-reviewed code.
