SAN FRANCISCO,CA – December 15,2025 – A novel operating system,dubbed CapROS,is emerging from progress,aiming to redefine system security and real-time capabilities. Built on the foundations of capability-based systems and modern resource management techniques, CapROS offers a unique blend of established principles and cutting-edge design. The system is designed to be small, secure, and provide what developers call “orthogonal persistence,” meaning data remains consistent and accessible even during system failures.
The Core of Capability-Based Security
At the heart of CapROS lies the concept of capabilities. Unlike traditional operating systems that rely on complex permission systems, capability-based systems grant access to resources based on possessing a unique, unforgeable “capability” token. this fundamentally alters the security landscape, limiting the potential damage from compromised software. Each program only has access to the resources it needs to function,drastically reducing the attack surface. Cloudflare details how capability-based security minimizes privilege escalation risks.
real-Time Performance and Orthogonal Persistence
Beyond security, CapROS is engineered for real-time performance. This makes it suitable for applications demanding predictable and immediate responses, such as industrial control systems, robotics, and embedded devices. The orthogonal persistence feature ensures data integrity and availability, even in the event of unexpected power loss or system crashes. This is achieved through a design where data storage is integrated directly into the core operating system, rather than relying on separate, potentially vulnerable layers.
A Legacy of innovation: From EROS to CapROS
CapROS isn’t appearing in a vacuum. It builds directly upon the earlier EROS project, inheriting its core principles and refining its implementation. EROS, developed in the early 2000s, pioneered many of the concepts now being realized in CapROS. The transition represents a continuation of decades of research into secure and reliable operating system design. The project is currently hosted on GitHub, leveraging the platform’s collaborative development tools.
Key Features and Specifications
Okay, here’s a breakdown of the provided text about CapROS, summarizing its key features and history.
Wikipedia‑Style Context
CapROS (Capability‑Based Runtime Operating System) is a research‑oriented, open‑source operating system that continues the legacy of the EROS (Extremely Reliable Operating System) project. EROS originated in the mid‑1990s at the University of Utah under DARPA‘s Secure Trusted Real‑Time Embedded Systems (STRESS) program, pioneering a capability‑based security model and orthogonal persistence. After a decade of academic refinement, the core concepts were commercialised by the university of Texas at Austin and later transplanted to the University of New South Wales, where the CapROS project was launched in 2007.
CapROS inherits EROS’s microkernel architecture, where the kernel provides onyl the minimal mechanisms needed for process isolation, capability management, and low‑level scheduling. All higher‑level services-file systems, networking, and device drivers-are implemented as user‑space servers that communicate via unforgeable capability tokens. This design dramatically reduces the trusted computing base (TCB) to roughly 100 KB of verified code, making formal verification practical.
The moast striking technical advance in CapROS is its implementation of orthogonal persistence. Unlike traditional OSes that treat storage as an after‑thought, CapROS treats persistent objects as first‑class citizens. When a program creates an object, it automatically becomes part of a persistent heap that survives crashes or power loss without requiring explicit checkpointing or journalling. The persistence mechanism is tightly coupled to the capability system,ensuring that only holders of the appropriate capabilities can resurrect or destroy persisted state.
Real‑time responsiveness is achieved through a priority‑based,preemptive scheduler that guarantees bounded latency for critical tasks. The scheduler integrates directly with the capability manager, allowing deterministic resource allocation while maintaining the security guarantees of the underlying model. CapROS is released under a BSD‑style license, freely available on GitHub, and has been used as a teaching platform for operating‑system courses at several universities.

The Looming Turbulence for US Travel: Beyond Summer Delays, a Crisis of ConfidenceA 9.2% projected drop in international visits to California this year isn’t just a blip on the radar; it’s a warning flare. The US travel industry, bracing for the 2026 World Cup and the 2028 Olympics in Los Angeles, is facing a confluence of challenges that extend far beyond typical seasonal fluctuations. From unsettling border encounters to slashed funding for critical infrastructure, a growing sense of uncertainty is threatening to derail a multi-trillion dollar sector and reshape the future of American tourism. The Border Effect: More Than Just HeadlinesThe anecdotes are piling up: international travelers facing lengthy detentions, denied entry with little explanation, and a general feeling of unwelcome. While the administration downplays these incidents, the narrative is taking hold overseas. This isn’t simply a matter of isolated cases; it’s a perception problem that directly impacts discretionary spending. As one industry executive anonymously told the Times, it feels like “stop helping us.” The chilling effect is real, particularly for high-value travelers who can easily choose alternative destinations. This erosion of trust in the US as a reliable and welcoming destination is a significant threat to long-term growth. Beyond Borders: A Cascade of DisruptionsThe issues extend beyond border security. Erratic tariff policies create economic instability, impacting consumer confidence and travel budgets. Perhaps more critically, cuts to essential services are undermining the very foundations of a smooth travel experience. The National Park Service, a cornerstone of American tourism, is facing staffing shortages, leading to closures and reduced services. Yosemite National Park, a prime example, saw bookings down as much as 50% leading into Memorial Day weekend. These aren’t just inconveniences; they’re tangible disruptions that damage the US’s reputation for quality and reliability. The Hidden Costs of Underfunding National ParksThe administration insists parks remain “open and accessible,” but the reality on the ground is far more nuanced. Park rangers are being stretched thin, forced to take on roles outside their expertise – biologists cleaning toilets, superintendents staffing visitor centers. Visitors are advised to “plan ahead,” bringing their own supplies and bracing for potential closures. This isn’t the welcoming experience tourists expect, and it’s a direct consequence of budgetary constraints. The National Parks Conservation Association highlights the tangible impact of these cuts, warning of fewer open entrance gates and limited facilities. The Weather Paradox: Cutting Forecasts While Climate Risks RiseThe situation is equally concerning in aviation. Decades of progress in weather forecasting, which significantly reduced flight delays, are now being reversed due to cuts at the National Oceanic and Atmospheric Administration (NOAA). Hundreds of positions have been eliminated, and further budget cuts are proposed. Rick Spinrad, former NOAA administrator, warns of increased flight delays and a broader erosion of the agency’s capabilities, impacting everything from emergency management to public safety. This is particularly alarming given the increasing frequency and intensity of extreme weather events, like atmospheric rivers in California, which require accurate forecasting for effective mitigation. NOAA Cuts: A Threat to More Than Just FlightsThe impact of NOAA cuts extends far beyond air travel. Reliable weather predictions are crucial for agriculture, water management, and disaster preparedness. The ability to accurately forecast phenomena like Santa Ana winds, which fuel devastating wildfires, is now at risk. The loss of skilled meteorologists and technicians is a long-term threat to the nation’s resilience and economic stability. As Mark Spalding of the Ocean Foundation points out, the situation is akin to the personnel shortages plaguing air traffic control – a recipe for potential disaster. Domestic Travel: A Partial Shield, But Not a SolutionCalifornia, while particularly vulnerable to shifts in Asian tourism, benefits from a strong domestic travel market, which accounts for 80% of tourism dollars. However, even this buffer isn’t immune to the broader climate of uncertainty. Widespread misperceptions about travel disruptions, fueled by negative media coverage, can deter even domestic travelers. Addressing these misperceptions through proactive communication and a commitment to improving the visitor experience is crucial. Looking Ahead: Rebuilding Confidence and Investing in ResilienceThe challenges facing the US travel industry are significant, but not insurmountable. Restoring consumer confidence requires a multi-pronged approach: clear and consistent messaging, a commitment to welcoming international visitors, and a renewed investment in the infrastructure and services that underpin a thriving tourism sector. The US must demonstrate a commitment to reliability and safety, not just for the 2026 World Cup and the 2028 Olympics, but for the long-term health of its tourism industry. Ignoring these warning signs risks not only a slower summer season but a lasting damage to America’s reputation as a premier global destination. What steps will the administration take to address these critical issues and ensure a welcoming and reliable travel experience for all?
